PTOL-90A (Rev. 04/07) UNITED STATES PATENT AND TRADEMARK OFFICE ____________ BEFORE THE BOARD OF PATENT APPEALS AND INTERFERENCES ____________ Ex parte HOGUE INDUSTRIES LLC Appellant ____________ Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 Technology Center 3900 ____________ Before SALLY C. MEDLEY, DANIEL S. SONG and KEN B. BARRETT, Administrative Patent Judges. MEDLEY, Administrative Patent Judge. DECISION ON APPEAL1 1 The two-month time period for filing an appeal or commencing a civil action, as recited in 37 C.F.R. § 1.304, or for filing a request for rehearing, as recited in 37 C.F.R. § 41.52, begins to run from the “MAIL DATE” shown on the PTOL-90A cover letter attached to this decision. Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 2 Hogue Industries LLC (“Hogue”), the owner of the patent under reexamination, appeals under 35 U.S.C. §§ 134(b) and 306 from a final Rejection of claims 1-19. We have jurisdiction under 35 U.S.C. §§ 134(b) and 306. We AFFIRM. STATEMENT OF THE CASE This reexamination proceeding arose from a third-party request for ex parte re-examination, filed by Gavin N. Manning (Request for Ex Parte Reexamination, filed 24 Jul. 2006). The current appeal is related to Appeal No. 2010-005881, Reexamination Control 90/008,968, Patent No. 7,201,554 which is decided concurrently with the present appeal. The ‘423 patent issued with 19 claims. Hogue amended claim 1. The Disclosed Invention Hogue’s patented invention is related to a machine and method for stacking lumber into packages. Col. 1, ll. 10-16. The subject matter of the appealed claims is illustrated by claim 1 (underlining removed), which defines the invention as: A material stacker, comprising: a frame; a plurality of stacking arms arranged along the frame in complementary pairs; a plurality of independent, electrically-controlled horizontal positioners configured to position the stacking arms in a horizontal relationship with respect to the frame; an electrically-controlled vertical positioner, separate from the horizontal positioners, said vertical positioner configured to position one or more of the stacking arms in a vertical relationship with respect to the frame; an electronic control system configured to control the operation of the stacker using the electrically-controlled positioners, wherein the electronic control system is configured Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 3 to control the speed, position, and acceleration of the stacking arms to stack a pre-staged layer of material at high speed by controlling the horizontal positioners. The Examiner relies on the following prior art references: Mason 3,169,646 Feb. 16, 1965 Larson 3,606,310 Sep. 20, 1970 Rysti (“Rysti”) 4,201,506 May 06, 1980 Rysti (“Rysti ‘781”) 4,274,781 Jun. 23, 1981 Johansson 4,290,723 Sep. 22, 1981 Vande Linde 5,613,827 Mar. 25, 1997 Dimion et al.

Claims 14-19 under 35 U.S.C. § 103(a) as unpatentable over any of Rysti, Rysti ‘781 or Johansson in view of DLS. ANTICIPATION ISSUE Has the Examiner erred in finding that Johansson describes an electronic control system configured to control the acceleration of the stacking arms to stack a pre-staged layer of material? FINDINGS OF FACT - ANTICIPATION 1. Zero acceleration corresponds to zero rate of change in speed and occurs when an object is stationary or moving at a constant speed. 2. Non-zero acceleration corresponds to any rate of change in the speed. Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 5 Johansson 3. Johansson describes, referring to Johansson’s figure 3 reproduced below [numbers from figure 3 inserted], a timber package arranger that includes two individually movable carrier planes [5], [6] and a feed conveyor [1] comprising a plurality of chains [2] having pushers [2a]. Col. 1, l. 59-col. 2, l. 3. Johansson’s figure 3 is below: Figure 3 depicts a timber package arranger. 4. The advancing movement of the carrier planes [5], [6] during assembly of a timber package layer directly from the feed conveyor [1] can take place continuously or in steps. Col. 3, ll. 26-28. 5. The movement of the carrier planes [5], [6] is controlled by the control unit in agreement with the speed of the feed conveyor [1] which can be adjusted as desired by a variator. Col. 1, l. 61-col. 2, l.3; col. 3, ll. 29-31; claims 4-5. 6. During the phase of cyclic movement in which a timber layer is assembled directly on a carrier plane from the conveyor [1], the carrier plane is advanced one step according to at least the width of the next timber piece to be advanced by the conveyor [1]. Col. 2, ll. 56-65; col. 3, ll. 5-8. Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 6 PRINCIPLES OF LAW – ANTICIPATION The recitation of a newly discovered function inherently possessed by the prior art structure does not cause a claim drawn to the newly discovered function to distinguish over the prior art. In re Swinehart, 439 F.2d 210, 212-213 (CCPA 1971). When the structural limitations are accounted for in the prior art, the absence of a disclosure related to function does not defeat a finding of anticipation. In re Schreiber, 128 F.3d 1473, 1477 (Fed. Cir. 1997) (“[A] structure [that] will be used to dispense popcorn does not have patentable weight if the structure is already known, regardless of whether it has ever been used in any way in connection with popcorn.”). When the functional limitations are found to be inherent in the prior art, the burden shifts to the applicant to show that the prior art structure does not inherently possess the functionally defined limitations of the claimed invention. Id. at 1478. ANALYSIS – ANTICIPATION Independent claim 1 recites: “the electronic control system is configured to control the . . . acceleration of the stacking arms to stack a pre- staged layer of material . . . .” Hogue argues that the meaning of control of the acceleration is too broadly construed. Reply Br. 2-3. Hogue argues that control of the acceleration refers to control of the amount, rate or ramping of acceleration and in support of its arguments directs us to portions of its Specification describing control of the ramping of the acceleration. Reply Br. 2-3, citing col. 5, l. 67-col. 6, l. 2; col. 6, ll. 14-16. To the extent that Hogue urges us to interpret the control of acceleration as control of the amount, rate or ramping of acceleration based Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 7 on one embodiment in its Specification, to the exclusion of another of its embodiments (i.e., general control of acceleration), we decline to do so. Claim terms should not be narrowly interpreted to exclude one of the preferred embodiments. Primos, Inc. v. Hunter’s Specialties, Inc., 451 F.3d 841, 847 (Fed. Cir. 2006). Rather, the broadest reasonable meaning is applied to claim terms according to their ordinary usage as they would be understood by persons of ordinary skill in the art while accounting for definitions found in the written description. In re Morris, 127 F.3d 1048, 1054 (Fed. Cir. 1997). Hogue does not direct us to an explicit definition in its specification necessitating a narrow meaning for control of acceleration. We are further unpersuaded by Hogue’s arguments that control of acceleration is more than simply incidental starts and stops. Reply Br. 3. The broadest reasonable meaning for control of acceleration includes not only the control of the amount, rate or ramping of acceleration, as argued by Hogue, but also includes control of zero acceleration and control of non-zero acceleration. Zero acceleration corresponds to zero rate of change in speed which occurs when an object is either stationary or moving at a constant speed. Non-zero acceleration corresponds to any rate of change in the speed. When an object is stopped it has zero acceleration, and when the object starts to move after being stopped it has non-zero acceleration. Since control of acceleration includes the control of zero acceleration and non-zero acceleration, the broadest reasonable meaning for control of acceleration also includes control of starting and stopping. The broadest reasonable interpretation rule recognizes that before a patent is granted claims are Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 8 readily amended as part of the examination process and that the applicant has the opportunity and responsibility to remove any ambiguity in the claim terms by amending as necessary. In re Bigio, 381 F.3d 1320, 1324 (Fed. Cir. 2004). This is also the standard for claim interpretation in reexamination proceedings. See In re Yamamoto, 740 F.2d 1569, 1571 (Fed. Cir. 1984); see also In re ICON Health and Fitness, Inc., 496 F.3d 1374, 1379 (Fed. Cir. 2007) ("During reexamination, as with original examination, the PTO must give claims their broadest reasonable construction consistent with the specification. Therefore, we look to the specification to see if it provides a definition for claim terms, but otherwise apply a broad interpretation."). If Hogue intended for control of acceleration to mean control of the amount, rate or ramping of acceleration, Hogue could have amended its claims accordingly. Johansson describes a timber package arranger including two individually movable carrier planes [5], [6] and feed conveyor [1] comprising a plurality of chains [2] having pushers [2a]. Col. 1, l. 59-col. 2, l. 3. The advancing movement of the carrier planes [5], [6] during assembly of a timber package layer directly from the feed conveyor [1] can take place continuously or in steps and is controlled by the control unit in agreement with the speed of the conveyor [1]. Col. 3, ll. 26-31; claims 4-5. More specifically, Johansson describes that during the phase of cyclic movement in which a timber layer is assembled directly on a carrier plane from the conveyor [1], the carrier plane is advanced one step according to at least the width of the next timber piece to be advanced by the conveyor [1]. Col. 2, ll. 56-65; col. 3, ll. 5-8. Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 9 Hogue argues that Johansson does not teach controlling or varying the acceleration of the carrier planes [5], [6] (i.e., stacking arms) because the electronic control unit is limited to coordinating the speed of the carrier planes [5], [6] in a direct relationship to the speed of the conveyor belt. App. Br. 11-12; Reply Br. 3-4. We are unpersuaded by Hogue’s arguments because Johansson describes moving the carrier planes in steps corresponding to the width of the timber pieces which demonstrates that the carrier plane movement (i.e., speed) is stopped and started. When Johansson’s carrier plane movement is stopped and started, the acceleration is controlled or varied from zero acceleration when the carrier plane movement is stopped to non-zero acceleration when the carrier plane movement is started. Hogue also argues that Johansson does not describe a material stacker that stacks a pre-staged layer of material, but instead the lugged chains [2], [2a] on the conveyor [1] that push individual pieces of timbers one at a time onto a layer assembling carrier plane would prevent the apparatus from stacking a pre-staged layer of material. App. Br. 10-11; Reply Br. 4-5. Hogue also argues that Johansson does not describe a control unit programmed in a manner to enable it to stack pre-staged layers of material since Johansson’s control unit is limited to coordinating the stacker arm and conveyor belt speed to formulate the layer of lumber. App. Br. 10-11; Reply Br. 4-5. The claim recitation of “to stack a pre-staged layer of material . . . .” is considered intended use, functional language. When the structural limitations are accounted for in the prior art, the absence of a disclosure Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 10 related to the intended use or function does not defeat the finding of anticipation. Schreiber, 128 F.3d at 1477. Johansson accounts for all of the structural limitations, but does not include a disclosure relating to the function or intended use of stacking a pre-staged layer of material. When the functional limitations are found to be inherent in the prior art, the burden shifts to the applicant to show that the prior art structure does not inherently possess the functionally defined limitations of the apparatus. Id. at 1478. Johansson’s apparatus would be capable of stacking a pre- staged layer of material if a set of several timber pieces (i.e., a pre-staged layer) was conveyed between each of the pushers [2a] instead of the single timber piece. If pre-staged layers of material were substituted for Johansson’s single timber pieces, the carrier plane located at the end of the conveyor [1] would assemble several pre-staged layers and then stack the pre-staged layers on the package. Since Johansson’s apparatus is capable of stacking pre-staged layers of material, the functional limitations do not distinguish from Johansson’s apparatus. Hogue does not sufficiently demonstrate that the prior art structure is incapable of stacking a pre-staged layer of material. Specifically, Hogue does not cogently explain: 1) how Johansson’s lugged chains [2], [2a] (i.e., chains with pushers) would prevent stacking of a pre-staged layer of material; and 2) how the programming or configuration of Johansson’s control unit would render the apparatus incapable of stacking a pre-staged layer of material. Lastly, Hogue’s arguments that Johansson teaches away from a pre- staged layer of material (App. Br. 10-11; Reply Br. 4-5) are misplaced Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 11 because whether a reference teaches away is inapplicable to anticipation. Celeritas Techs, Ltd. v. Rockwell Int’l. Corp., 150 F.3d 1354, 1361 (1998). For all these reasons, we sustain the Examiner’s rejection of claims 1- 2 and 9 as anticipated by Johansson. OBVIOUSNESS ISSUE Has the Examiner erred in determining that the claims are prima facie obvious over the applied prior art and did the Examiner not accord appropriate weight to Hogue’s evidence of secondary considerations? ADDITIONAL FINDINGS OF FACT - OBVIOUSNESS DLS 7. DLS describes, referring to DLS’ figure reproduced below, a lumber stacker with a single set of forks that are lifted and extended out over a stack of lumber at high speed, and then lowered onto the top of the stack and retracted. P. 1, ¶ 3. DLS’ figure is below: DLS’ figure depicts a lumber stacker 8. The forks are mounted on a carriage that is moved back and forth by a hydraulic cylinder and the forks are raised and lowered by a hydraulic cylinder mounted on the carriage. P. 2, ¶ 7. 9. All of the hydraulic cylinder positions are controlled by a motion controller CPU (central processing unit). P. 2, ¶ 8. Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 12 10. The motion controller CPU provides high speed coordinated movement necessary for maximum stacker feed rates. P. 1, ¶ 2. 11. The fork extention and retraction are done with S curves to smooth the motion profile. P. 1, ¶ 2, p. 3, ¶ 4. 12. DLS describes an Event Control Table used to coordinate the fork lift and fork extention axes, including control of velocity and acceleration parameters. P. 3-4. Rysti 13. Rysti describes a lumber stacker that transports a layer of lumber from a lifting location to the top of a stack of lumber being formed. Abs.; col. 3, ll. 46-62; figs. 1-3. 14. Rysti describes, referring to Rysti’s figures 8 and 9 reproduced below [numbers from figures 8 and 9 inserted], a lumber stacker including a central pair of lifting arms [36] and an outer pair of lifting arms [36a], [36b]. Col. 3, l. 33-col. 4, l. 14; col. 8, l. 56-col. 9, l. 12. Rysti’s figure 8 is below: Figure 8 depicts a transverse elevation view of the lumber stacker. Rysti’s figure 9 is below: Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 13 Figure 9 depicts a plan view of the lumber stacker. 15. Central pair of lifting arms [36] are supported on a central carriage [68] and moved between extended and retracted positions by the endless chains [102] and vertically raised and lowered by hydraulic cylinders [78], [80] that are actuated by mechanical switches. Col. 4, ll. 34-38; col. 5, ll. 6-15; col. 7, l. 13-col. 8, l. 8; col. 8, ll. 45-55; col. 10, ll. 13-16; fig. 11. 16. Outer lifting arms [36a], [36b] are supported by carriages [122], [124] and moved between extended and retracted positions by endless chains [158] and vertically raised and lowered by hydraulic cylinders [142], [144] that are actuated by mechanical switches. Col. 8, l. 56- col. 9, l. 48; col. 10, ll. 4-22; fig. 10. 17. Utilizing two pairs of stacking arms makes it possible to form a stack in approximately half the time required if only one pair of arms were utilized, and at the same time, the conveyor means can be utilized to its full potential. Col. 9, l. 49-col. 10, l. 4; col. 10, ll. 23-39. PRINCIPLES OF LAW – OBVIOUSNESS The question of obviousness is resolved on the basis of underlying factual inquiries including: 1) the scope and content of the prior art; 2) any differences between the claimed subject matter and the prior art; 3) the level Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 14 of skill in the art; and 4) any evidence of secondary considerations, if present. Graham v. John Deer Co., 383 U.S. 1, 17-18 (1966). The Examiner bears the initial burden of presenting a prima facie case of obviousness, and if that burden is met, the burden shifts to the patent owner to come forward with evidence or argument in rebuttal. In re Oetiker, 977 F.2d 1443, 1445 (Fed. Cir. 1992). Prima facie obviousness can be rebutted by presenting evidence of secondary considerations and when such evidence is submitted, all of the evidence must be considered anew. In re Piasecki, 745 F2d 1468, 1472-1473 (Fed. Cir. 1984). Secondary considerations include: long-felt but unsolved needs, failure of others, unexpected results, commercial success, copying, licensing, and praise. In re Rouffet, 149 F.3d 1350, 1335 (Fed. Cir. 1998); U.S. Surgical Corp. v. Ethicon, Inc., 103 F.3d 1554, 1565 (Fed. Cir. 1997). Evidence of secondary considerations, when present, must always be considered en route to the determination of obviousness. Stratoflex, Inc. v. Aeroquip Corp., 713 F.2d 1530, 1538 (Fed. Cir. 1983). Secondary considerations are only a part of the “totality of the evidence”; its mere existence does not control the conclusion of obviousness. Richardson-Vicks Inc. v. Upjohn Co., 122 F.3d 1476, 1483 (Fed. Cir. 1997) (citations omitted). In order to be accorded substantial weight, there must be a nexus between the merits of the claimed invention and the evidence of secondary considerations. Stratoflex, 713 F.2d at 1539; In re Huang, 100 F.3d 135, 140 (Fed. Cir. 1996); Cable Elec. Products, Inc. v. Genmark, Inc., 770 F.2d 1015, 1027 (Fed. Cir. 1985); In re GPAC Inc., 57 F.3d 1573, 1580 (Fed. Cir, 1995). A “nexus” is a legally and factually sufficient connection between Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 15 the objective evidence and the claimed invention such that the objective evidence should be considered in the determination of obviousness. In re Paulsen, 30 F.3d 1475, 1482 (Fed. Cir. 1994). The burden of showing that there is a nexus lies with the patent owner. Id. It is also well settled that evidence of secondary considerations must be commensurate in scope with the claims in which the evidence is offered to support. In re Grasselli, 713 F.2d 731, 743 (Fed. Cir. 1983). “[L]ong-felt need is analyzed as of the date of an articulated identified problem and evidence of efforts to solve that problem.” Texas Instruments Inc. v. U.S. Int’l Trade Comm’n, 988 F.2d 1165, 1178 (Fed. Cir. 1993). To establish a long-felt but unmet need for the claimed invention, the objective evidence must show that the need was a persistent one that was recognized by those of ordinary skill in the art. In re Gershon, 372 F.2d 535, 538 (CCPA 1967). The objective evidence must further show that the claimed invention satisfied the long-felt need that was not previously satisfied by another. In re Cavanaugh, 436 F.2d 491, 496 (CCPA 1971); Newell Companies, Inc. v. Kenney Mfg. Co., 864 F.2d 757, 768 (Fed. Cir. 1988). ANALYSIS – OBVIOUSNESS Rejection of claims 1-2 and 5-8 over DLS in view of Rysti or Johansson Scope and Content of the Prior Art DLS describes a lumber stacker with a set of forks that are lifted and extended out over a stack of lumber at high speed, then lowered onto the top of the stack and then retracted. P. 1, ¶ 3. The forks are mounted on a carriage that is moved back and forth by a hydraulic cylinder (i.e., a horizontal positioner) and raised and lowered by a hydraulic cylinder (i.e., a Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 16 vertical positioner) mounted on the carriage. P. 2, ¶ 7. All of the hydraulic cylinder positions are controlled by a motion controller CPU which provides high speed coordinated movement necessary for maximum stacker feed rates. P. 1, ¶ 2; p. 2, ¶ 8. The fork extension and retraction are done with S curves to smooth the motion profile. P. 1, ¶ 2; p. 3, ¶ 4. The acceleration and deceleration is controlled during the fork movement. P. 3-4; DLS’ Event Control Table. Rysti describes a lumber stacking apparatus including a pair of central lifting arms [36] and an outer pair of lifting arms [36a], [36b]. Col. 3, l. 33- col. 4, l. 14; col. 8, l. 56-col. 9, l. 12; figs. 8-9. Johansson also describes a timber package arranger with two individually movable carrier planes [5], [6]. Col. 1, l. 59-col. 2, l. 3. The Examiner finds that the use of two stacking arms would provide the advantage of moving more material or moving lumber at a faster rate than with only one arm. Ans. 5, 6. Differences Between the Prior Art and the Claimed Invention The Examiner finds that DLS does not describe using two stacking arms (i.e., forks). Ans. 4. Level of Ordinary Skill in the Art Neither Hogue nor the Examiner has addressed the level of ordinary skill in the art. A “person of ordinary skill in the art is a hypothetical person who is presumed to know the relevant prior art.” In re GPAC, 57 F.3d 1573, 1579 (Fed. Cir. 1995) (quoting Custom Accessories, Inc. v. Jeffrey-Allan Indus. Inc., 807 F.2d 955, 962 (Fed. Cir. 1986)). Accordingly, we consider the cited prior representative of the level of ordinary skill in the art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 17 Prima Facie Case In view of the underlying factual inquiries discussed before, we review the prima facie case of obviousness. The Examiner determined that it would have been obvious to one with ordinary skill in the art at the time the invention was made to modify DLS’ invention to include two stacking arms as suggested by either Rysti or Johansson for the advantage of moving more material or moving lumber at a faster rate than with only one arm. Ans. 5, 8. Hogue argues that DLS teaches away from using dual-carriage stackers (i.e., two stacking arms) because DLS teaches a single carriage stacking arm, despite the fact that dual carriage stacking arms were known and used. App. Br. 15. Hogue also argues that Rysti teaches away from using a plurality of independent, electrically controlled horizontal positioners because Rysti’s common drive system greatly reduces the power required for carrying out the operations and provides a simple apparatus that requires only a small space. App. Br. 15. Neither DLS’ teaching of using a single carriage stacking arm nor Rysti’s teaching of using a common drive system constitute a teaching away because neither reference suggests that any developments based on its disclosure would be unlikely to produce the objective of Hogue’s invention (a faster material stacker). See Syntex (U.S.A.) v. Apotex, Inc., 407 F.3d 1371, 1380 (Fed. Cir. 2005). DLS’ and Rysti’s teachings of something different do not constitute a teaching away. See In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004) ("the prior art's mere disclosure of more than one alternative does not constitute a teaching away from any of these alternatives Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 18 because such disclosure does not criticize, discredit, or otherwise discourage the solution claimed"). Hogue also argues that the references do not provide a teaching, suggestion or motivation to combine the references, but instead the obviousness determination was based on hindsight reconstruction. App. Br. 26-27. It is not necessary to find precise teachings in the prior art directed to the specific subject matter claimed. KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 418 (2007). Rather, inferences and creative steps that a person of ordinary skill in the art would employ can be taken into account. Id. Nonetheless, the reasoning used for combining the references is supported by Rysti’s teaching that an arrangement using two pairs of arms makes it possible to form a lumber stack in approximately half the time which would be required if only one pair of arms were utilized, while at the same time utilizing the full potential of the conveyor. Col. 10, ll. 23-39. We also recognize that any judgment on obviousness is in a sense necessarily a reconstruction based upon hindsight reasoning, but is proper so long as it takes into account only knowledge which was within the level of ordinary skill at the time the claimed invention was made and does not include knowledge gleaned only from applicant’s disclosure. In re McLaughlin, 443 F.2d 1392, 1395 (CCPA 1971). In this case, the determination of obviousness is based on the knowledge of one with ordinary skill in the art, who would have recognized that it would have been desirable to move more lumber or move lumber at a faster rate. Hogue does not otherwise argue that the determination of obviousness was based on knowledge gained only from its disclosure. Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 19 For all of these reasons, the Examiner did not error in determining that claims 1-2 and 5-8 are prima facie obvious over DLS in view of Rysti or Johansson. Rejection of claims 1-2 over Rysti in view of Johansson and DLS Scope and Content of the Prior Art Rysti’s central pair of lifting arms [36] and outer pair of lifting arms [36a], [36b] are vertically raised and lowered by hydraulic cylinders [78], [80] and [142], [144] that are actuated by several mechanical switches. Col. 3, l. 33-col. 4, l. 14; col. 4, ll. 34-38; col. 5, ll. 6-15; col. 7, ll. 13-54; col. 8, l. 45-col. 9, l. 12; col. 10, ll. 4-22; figs. 10-11. The central pair of lifting arms [36] and outer lifting arms [36a], [36b] are moved forward and backward (i.e., horizontally) between extended and retracted positions by way of endless chains [102] and [158]. Col. 7, l. 55-col. 8, l. 8; col. 8, l. 56-col. 9, l. 48. Johansson describes controlling the movement of the carrier planes [5], [6] (i.e., stacking arms) with a control unit. Col. 2, ll. 7-10; col. 3, ll. 27- 32. DLS’ lumber stacker utilizes a motion controller CPU to control the hydraulic cylinders that move the set of forks. P. 2, ¶¶ 7-8. The Examiner finds that Johansson and DLS suggest using an electronic control system which provides the advantage of automating Rysti’s process with precise control. Ans. 4. Differences Between the Prior Art and the Claimed Invention The Examiner finds that Rysti does not describe an electronic control system. Ans. 4. Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 20 Level of Ordinary Skill in the Art The cited prior art is representative of the level of ordinary skill in the art. See Okajima, 261 F.3d at 1355. Prima Facie Case The Examiner determined that it would have been obvious to one with ordinary skill in the art at the time the invention was made to modify Rysti’s system to include an electronic control system as suggested by Johansson and DLS for the advantage of automating the process with precise control. Ans. 5. Hogue argues that Johansson teaches away from the claimed invention which requires a pre-staged material layer and a different type of electronic control since Johansson is directed toward eliminating pre-staged layers and the electronic control is limited to matching the carrier plane [5], [6] (i.e., stacker arm) speed to the conveyor speed. App. Br. 15, 27, 29; Reply Br. 13. Hogue’s arguments are misplaced. As explained before, the recitation “to stack a pre-staged layer of material . . .” is considered intended use, functional language. Moreover, Rysti, the primary reference relied upon in the Examiner’s rejection, describes stacking pre-staged layers of material. Abs.; col. 3, ll. 46-62; figs. 1-3. Additionally, Hogue’s arguments that Johansson’s electronic control is limited to matching the stacking arm speed to the conveyor speed focuses on the specific teachings of the Johansson reference while entirely ignoring the electronic control of horizontal positioners described in DLS by its operation of the carriage. Ans. 6. Hence, Hogue's argument fails in that, in essence, Hogue argues the references individually and do not take into Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 21 account what the collective teachings of the prior art would have suggested to one of ordinary skill in the art. See In re Keller, 642 F.2d 413, 425 (CCPA 1981) ("The test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference; nor is it that the claimed invention must be expressly suggested in any one or all of the references. Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art"); see also In re Merck, 800 F.2d 1091, 1097 (Fed. Cir. 1986). Moreover, the use of patents as references is not limited to what the patentees describe as their own inventions or to the problems with which they are concerned, as they are a part of the literature and relevant for all they contain. In re Heck, 699 F.2d 1331, 1333 (Fed. Cir. 1983) (citations omitted). Hogue’s arguments that utilizing DLS’ S curves in Johansson or Rysti would not work and is not suggested by the references (App. Br. 27, 29) are misplaced since the Examiner does not propose utilizing DLS’ S curves for controlling stacking arm speed and motion in Johansson or Rysti. Rather, the Examiner determined that it would have been obvious to modify Rysti’s mechanically controlled system to include an electronic control system as suggested by Johansson and DLS. Ans. 6. Hogue’s arguments that the references do not suggest the complex control needed to provide the claimed interaction between the two electronically-operated complementary sets of stacking arms (App. Br. 27) are not commensurate in scope with the claim limitations. Claim 1 does not Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 22 require a controller configured to control the interaction between two electronically-operated complementary sets of stacking arms. Hogue’s additional arguments that the references do not provide a teaching, suggestion or motivation to combine (App. Br. 26-27) are unpersuasive because it is not necessary to find precise teachings in the prior art directed to the specific subject matter claimed. KSR, 550 U.S. at 418. Instead, inferences and creative steps that a person of ordinary skill in the art would employ can be taken into account. Id. As explained by the Examiner, at the time the invention was made, one with ordinary skill in the art would have recognized that utilizing electronic motion control would offer the advantage of automating the process with precise control. A person of ordinary skill in the art would have further recognized that utilizing electronic motion control would improve similar lumber stacking machines by offering the same advantage of automating the process with precise control. If a technique has been used to improve one process, and a person of ordinary skill in the art would recognize that it would improve similar processes in the same way, using the technique is obvious unless its actual application is beyond his or her skill. KSR, 550 U.S. at 417. Hogue does not direct us to objective evidence to demonstrate that applying an electronic motion controller to Rysti’s mechanically controlled lumber stacker would have been beyond the skill level of one with ordinary skill in the art. Hogue’s related argument that hindsight construction was utilized in the determination of obviousness (App. Br. 26-27) is unpersuasive because Hogue does not cogently explain how obviousness was based on knowledge gained only from Hogue’s disclosure. Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 23 Lastly, Hogue’s arguments that the proposed combination would require extensive structural and control modifications not contemplated by the references (App. Br. 27) are conclusory and do not offer a meaningful explanation of the necessity for structural and control modifications. Argument of counsel cannot take the place of evidence lacking in the record. Meitzner v. Mindick, 549 F.2d 775, 782 (CCPA 1977); see also In re Pearson, 494 F.2d 1399, 1405 (CCPA 1974). For all of these reasons, we conclude that the Examiner has not erred in determining that claims 1-2 are prima facie obvious over Rysti in view of Johansson and DLS. Additional Rejections of Claims 3-19 as Obvious over the Applied Prior Art Claims 5-8 were rejected as obvious over Rysti or Johansson in view of DLS or Dimion. Hogue does not specifically address the limitations of claims 5-8. Instead, Hogue argues that: 1) Dimion does not teach complimentary-operating stacking arms; and 2) providing an additional set of horizontally complimentary moving stacking arms to Dimion would greatly increase the complexity of Dimion’s device. App. Br. 16. Hogue’s arguments are not commensurate in scope with the claim language since claim 5 does not recite complimentary-operating or moving stacking arms. Claim 5 merely requires that the stacking arms are arranged along the frame in complimentary pairs. Hogue’s arguments also attack the Dimion reference separately rather than addressing the combination of references. One cannot show non-obviousness by attacking references individually where the rejections are based on combinations of references. In re Merck, 800 F.2d at 1097. Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 24 For all these reasons, in addition to those explained supra with respect to the rejections of claims 1-2, the Examiner did not err in determining that claims 5-8 are prima facie obvious over Rysti or Johansson in view of DLS or Dimion. Claims 3-4 were rejected as obvious over Rysti in view of DLS and Larson. Hogue does not specifically address the limitations of claims 3-4, but instead argues that the addition of Larson does not remedy the deficiencies of the combination of Rysti and DLS. App. Br. 28. For the same reasons as those explained before addressing the rejections of claims 1- 2, we find no error in the Examiner's determination that claims 3-4 are prima facie obvious over Rysti in view of DLS and Larson. Claims 9-12 were rejected as obvious over Johansson in view of DLS; Dimion in view of Johansson or DLS; and Mason in view of DLS and further in view of Larson, Rysti, Van Linde or Johansson. Hogue argues that the rejection of claims 9-12 over Dimion in view of Johansson or DLS is improper, because Johansson is directed to a different purpose than either Dimion or DLS (App. Br. 29). The argument is unpersuasive because the intended purpose of Johansson need not be preserved. See Heck, 699 F.2d at 1333. Hogue’s argument specifically addressing the rejection of claims 9-12 over Johansson in view of DLS are similar to the arguments addressed before with respect to claims 1-2. Compare App. Br. 29 with App. Br. 27. For the same reasons as those explained before with respect to claims 1-2 and 5-8, we find no error in the Examiner's determination that claims 9-12 are prima facie obvious over the applied prior art. Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 25 Claims 13-19 were rejected as obvious over various combinations of the applied prior art. Hogue does not present arguments directed to limitations of claims 13-19, the deficiencies of the applied prior art, or the determinations of obviousness. App. Br. 29-30. For the same reasons as those explained before with respect to claims 1-12, we find no error in the Examiner's determination that claims 13-19 are prima facie obvious over the applied prior art. In conclusion, we find no error in the Examiner's determination that the subject matter of Hogue’s claims 1-19 is prima facie obvious over the applied prior art. Since Hogue directs us to arguments and evidence of secondary considerations to rebut the prima facie case for obviousness, we now turn to consider the arguments and evidence. Secondary Considerations Secondary considerations may include any of the following: long-felt but unsolved needs, failure of others, unexpected results, commercial success, copying, licensing, and praise. Hogue argues all of these. In support of Hogue’s arguments that the claimed invention would not have been obvious based on secondary considerations, Hogue relies on a declaration made by inventor G.W. Hogue and “exhibits” A-E attached thereto. App. Br. 37. At the outset, Hogue argues that the Examiner improperly ignored, discounted or dismissed G.W. Hogue’s testimony and the attached exhibits A-E. App. Br. 16-17, 25; Reply Br. 6-11, 13-16. We disagree that the Examiner ignored, discounted or dismissed the submitted evidence. The Examiner did consider the evidence. Final Rejection 19-21; Ans. 16-18. To Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 26 the extent that the Examiner questions the credibility of G.W. Hogue’s testimony because he is an inventor, there is nothing inherently wrong with the Examiner doing so. A witness’ interest is important in determining the weight to be given declaration evidence submitted during ex parte patent examination. Accord, Pargon Podiatry Lab., Inc. v. KLM Lab., Inc., 984 F.2d 1182, 1191 (Fed. Cir. 1993) (Holding inequitable conduct resulted from the failure to disclose to the examiner that the declarants who testified supporting patentability had a significant financial stake in the assignee of the invention.); Refac Int’l, Ltd. v. Lotus Development Corp., 81 F.3d 1576, 1582 (Fed. Cir. 1996) (holding that applicant committed inequitable conduct in withholding information on the inventor’s significant prior connections with the affiants - the prior connection was considered material in deciding the weight to be given affidavits supporting the patentability of the claims). Apparent from the Examiner’s actions is that Hogue’s interest in the outcome of the proceeding was only one of several reasons for not according substantial weight to the submitted evidence. Final Rejection 19-21; Ans. 16-18. It was not the sole reason. Accordingly, we are not persuaded that the Examiner ignored G.W. Hogue’s testimony and the exhibits A-E. We recognize that evidence of secondary considerations must always be considered en route to the determination of obviousness, but its existence alone does not control the conclusion of obviousness. Richardson-Vicks, 122 F.3d at 1483. The weight given to evidence of secondary considerations is dependent upon whether there is a nexus between the merits of the claimed invention and the evidence offered. Stratoflex, 713 F.2d at 1539. The claimed invention, as illustrated by claim 1, is a stacker including a Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 27 plurality of stacking arms, a plurality of horizontal positioners, and an electronic control system configured to control the speed, position, and acceleration of the stacking arms by controlling the horizontal positioners. For the reasons that follow, the evidence of nonobviousness that Hogue directs us to is not entitled to substantial weight because the evidence factually is not commensurate in scope with the invention claimed by Hogue. Long-Felt but Unsolved Need and Failure of Others Hogue argues that there was a long-felt but unmet need in the industry for faster stacking rates and a more reliable stacker design and that their invention solves the long-felt need. App. Br. 17-19; Reply Br. 9-10. In support of its arguments, Hogue directs our attention to paragraphs 11-17 of the Declaration of G.W. Hogue who testifies that there was a long-felt but unmet need for: 1) higher speed lumber stacking equipment, particularly with a production rate ideally in the range of 24 to 30 cycles per minute (CPM); and 2) a more reliable stacking system with fewer maintenance issues and less down-time capable of high rates of production. App. Br. 17- 21, Reply Br. 8-10; Hogue Dec. ¶¶ 11-17. Hogue also directs our attention to the cited prior art in support of the argument that there was a long felt need for higher stacking rates. App. Br. 14, 17-18, citing Mason col. 1, ll. 40-47; Larson, col. 1, ll. 60-68; Rysti col. 1, ll. 44-57, col. 2, ll. 13-23; Van Linde col. 1, ll. 49-54 and Dimion col. 1, ll. 22-23. Although the cited prior art may demonstrate that there was a general need for faster lumber stackers as early as 1965, Hogue does not explain, nor direct us to where in the cited prior art there is support for G.W. Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 28 Hogue’s testimony that there was a long-felt need for production rates in the range of 24 to 30 CPM (cycles per minute) or a long-felt need for a more reliable stacking system with fewer maintenance issues and less down-time. See Hogue Dec. ¶¶ 15-17. In addition, Hogue’s arguments and evidence do not demonstrate that a person of ordinary skill in the art trying to solve the problem for faster lumber stackers was aware of the prior art cited by the Examiner. Satisfaction of a long-felt but unresolved need is not evidence of nonobviousness unless it is shown that widespread efforts of skilled workers having knowledge of the prior art had failed to find a solution to the problem. In re Allen, 324 F.2d 993, 997 (CCPA 1963). See also Toledo Pressed Steel Co. v. Standard Parts, Inc., 307 U.S. 350, 356 (1939). Hogue further argues that others have failed to solve the long felt need. Specifically, Hogue argues that operating a single arm stacking device at faster rates and Dube’s dual carriage stacker (Patent No. 6,655,902) failed to solve the long-felt needs. App. Br. 19-21; Reply Br. 9-10. In support of its arguments, Hogue directs us to evidence to show that: 1) the speed of single fork machines could only be increased a limited amount and resulted in additional maintenance issues and increased down time; and 2) Dube’s invention failed to perform consistently, had extensive upkeep requirements and incurred substantial costs in terms of production interruption, equipment maintenance, parts replacement and down-time. Hogue Dec. ¶¶ 18-30; Ex E. The evidence to which Hogue’s directs us is insufficient to show that the long-felt need for higher speed lumber stacking equipment and a more reliable stacking system was not previously satisfied by Dube. Objective Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 29 evidence must show that the long-felt need was not previously satisfied by another. Newell, 864 F.2d at 768. Contrary to Hogue’s arguments, Hogue’s evidence shows that Dube’s dual carriage stacker invention satisfied the need for higher speed lumber stackers since G.W. Hogue testifies that Dube’s “dual stacking arm design helped . . . to increase the speed of lumber production . . . .” Hogue Dec. ¶ 25. Hogue’s evidence also does not sufficiently show that Dube failed to satisfy the need for a more reliable stacking system with fewer maintenance issues and less down-time. G.W. Hogue’s testimony that Dube’s “dual stacking arm design . . . failed over time due to its intensive upkeep requirements” and “was found to be both cost and labor intensive in terms of up-front expense, adjustment, maintenance, and down time” is not supported by a sufficient factual basis. Hogue’s evidence does not provide an objective measurement of Dube’s upkeep requirements, costs and labor. Nor does Hogue’s evidence demonstrate the levels of upkeep, costs and labor that would be unacceptable and indicative of a failure to satisfy the need for a more reliable stacker. It would appear that whether a lumber stacker is deemed to have intensive upkeep requirements or to be cost and labor intensive will depend on many situation specific factors such as, for example, the machine operating hours per day/week/month and the hourly rates of skilled labor providers. Therefore, Hogue’s evidence is not sufficiently supported by a factual basis. In addition, the evidence to which Hogue directs us is insufficient to show that the claimed invention satisfies the long-felt need because it is not commensurate in scope with the claim limitations. Hogue Dec. ¶¶ 11-31; Ex’s D, E. For example, in many instances the invention is characterized in Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 30 broad and general terms in the Declarations of G.W. Hogue, and William P. Bowlin and in the letter from Leo Campbell. Hogue Dec.; Ex’s D- E. The broad and general characterization of the invention does not enable us to determine whether it is the claimed invention or an unclaimed embodiment which is described in the evidence. Although Hogue’s solution to the long- felt need is more specifically characterized in a few instances, these characterizations also do not enable us to determine whether it is the claimed invention that satisfies the long-felt need. For example, Hogue’s solution is described as “an electronically controlled dual carriage stacker that offers independent, synchronized positioning and sequencing of opposing sets of stacking arms.” Hogue Dec. ¶ 31. None of the claims on appeal recite “independent, synchronized positioning and sequencing of opposing sets of stacking arms”. The objective evidence must show that the claimed invention satisfies the long-felt need. Cavanaugh, 436 F.2d at 496 (emphasis added). Hogue does not otherwise direct us to evidence connecting the merits of the claimed invention (i.e., a stacker including an electronic control system configured to control the speed, position, and acceleration of the stacking arms by controlling the horizontal positioners) to a long-felt but unmet need. Accordingly, Hogue does not meet its burden of showing a nexus. Related to the previous arguments, Hogue also argues that the claimed invention would not have been obvious because the applied prior art references co-existed for a number of years before Hogue’s invention, yet no one thought to use its teachings, either alone or in combination, to create the claimed invention. App. Br. 14, 28-30; Reply Br. 11-12. Without a Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 31 showing of long-felt need or failure of others, the mere passage of time without the claimed invention cannot substitute for objective evidence of non-obviousness. In re Khan, 441 F.3d 977, 990-991 (Fed. Cir. 2006) (citations omitted). Moreover, Hogue’s evidence does not demonstrate that those skilled in the art were aware of the cited prior art references and the problems disclosed therein. See Allen, 324 F.2d at 997 (CCPA 1963). See also Toledo Pressed Steel Co., 307 U.S. at 356. Unexpected Results Hogue argues that the invention produced unexpected results. In support of its arguments, Hogue directs our attention to G.W. Hogue’s Declaration in which he testifies that unexpected results were produced from an embodiment of the invention in which the positioning and tracking of each horizontal and vertical drive system can be determined and controlled independent from one another, while providing synchronized sequencing within each set of arms and between one set of arms to the other set of arms App. Br. 21-22; Reply Br. 13-14, citing Hogue Dec. ¶¶ 42-45. Hogue’s evidence is not commensurate in scope with the claims because the claimed invention is not limited to an embodiment in which the positioning and tracking of each horizontal and vertical drive system can be determined and controlled independent from one another, while providing synchronized sequencing. Hogue also argues that it was unexpected for its invention to exhibit significant improvements over the prior art and for many mills to use its invention. App. Br. 22-23. In support of its arguments, Hogue directs our attention to evidence that describes the invention in broad and general terms, Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 32 e.g. “using this invention . . .” (Hogue Dec. ¶¶ 46-47), which does not establish a correlation between the alleged significant improvements and the invention set forth in the claims. We are not provided with evidence as to what “this invention” refers to, but are essentially asked to rely on the assertion that a nexus between the improvements and the claims exists. Hogue does not otherwise direct us to evidence linking the merits of the claimed invention to evidence of unexpected results. Accordingly, Hogue does not meet its burden of showing a nexus. Commercial Success Hogue argues that its invention has enjoyed commercial success and in support of its arguments directs our attention to G.W. Hogue’s Declaration in which he testifies that six machines have been sold by Hogue, and numerous dual fork stackers using Hogue’s design have been built and/or sold by other companies. App. Br. 23-24; Reply Br. 14-16; citing Hogue Dec. ¶¶ 50-61. The evidence that Hogue directs us to at best provides a general connection between the alleged commercial success and a broad characterization of Hogue’s invention; e.g., “our invention”, “our innovative design”, “dual fork stacker using our technology”, “dual fork stacker using the technology disclosed and claimed in our ‘423 Patent”. Hogue Dec. ¶¶ 50-60. Such broad brush statements are insufficient to link any commercial success to the claimed invention. To this end, Hogue’s testimony is conclusory and unsupported by a sufficient factual basis. Although G.W. Hogue does assert, in one instance that commercial success is due to a “dual fork stacker having independent, electronically- Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 33 controlled drives for each set of stacker arms” (Hogue Dec. ¶ 61), that assertion is also not commensurate in scope with the claims. The claims on appeal do not recite a “dual fork stacker having independent, electronically- controlled drives for each set of stacker arms.” Even if Hogue’s evidence does demonstrate a sufficient nexus between the evidence of sales and the merits of the claimed invention, which we find that it does not, Hogue’s showing is also deficient because the evidence Hogue directs us to does not provide an indication of Hogue’s market share so as to put Hogue’s sales numbers into perspective in the context of the lumber stacker market and clearly establish commercial success. “[E]vidence related solely to the number of units sold provides a very weak showing of commercial success, if any.” Huang, 100 F.3d at 140. Licensing and Copying Licensing Hogue argues that others have licensed its invention. In support of the argument, Hogue directs our attention to G.W. Hogue’s Declaration in which he testifies that a business named Carbotech acquired a license from Hogue and built one embodiment of the dual fork stacker disclosed in Hogue’s Patent App. Br. 24-25; Reply Br. 10-11; Hogue Dec. ¶¶ 35-36. In support of G.W. Hogue’s testimony, Hogue directs our attention to a letter purportedly from Leo Campbell attached as exhibit E to G.W. Hogue’s Declaration. In the letter, reference is made to an invention built by Carbotech that is characterized as the “Hogue Dual Fork Stackers . . . with the positioning and electrical/electronic controls”. Hogue Dec. Ex. E. Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 34 Again, the evidence to which Hogue directs us to is not commensurate in scope with the claims. The claims on appeal do not recite a dual fork stacker with positioning and electrical/electronic controls. It is not clear, based on the record, what Carbotech built and whether the built device is directed to the claimed invention. Lastly, the evidence to which Hogue directs us to does not provide the terms of the license agreement or describe the specific subject matter encompassed by the license agreement. Copying Hogue also argues that others have copied its invention. In support of the argument, Hogue again directs our attention to G.W. Hogue’s Declaration. He testifies that a business named Mill Tech copied Hogue’s “innovative design”, built three or four stackers using the technology disclosed in the ‘423 patent, and advertise a dual fork stacker implementing Hogue’s invention. App. Br. 24-25; Reply Br. 10-11; Hogue Dec. ¶¶ 52-55; Ex. A. G. W. Hogue also testifies that a business named Comact (1) built dual carriage lumber stackers incorporating Hogue’s “innovative design” and (2) has displayed a copy of Hogue’s “dual fork stacker having independent electronically- controlled drives for each set of stacker arms” at a trade show. Hogue Dec. ¶¶ 60-61, Ex’s B-C. The evidence which Hogue directs our attention to is vague and not commensurate in scope with the claims. The claims on appeal do not recite a dual fork stacker having independent electronically-controlled drives for each set of stacker arms. Moreover, the characterizations such as (1) an innovative design, (2) a dual fork stacker implementing Hogue’s invention and (3) a dual carriage lumber stacker incorporating Hogue’s design are all Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 35 broad general assertions which fail to persuasively establish that the machines built by Mill Tech and Comact incorporate the features of the Hogue machines which is alleged to correspond to the claimed invention. Based on the record before us it is unclear whether Mill Tech and Comact copied Hogue’s invention due to the claimed features of the invention, e.g., a stacker with an electronic control system configured to control the speed, position, and acceleration of the stacking arms by controlling the horizontal positioners. Accordingly, Hogue does not meet its burden of showing a nexus between the evidence of licensing and copying and the merits of the claimed invention. Industry Praise Hogue argues that its invention has received praise and recognition in the industry, directing our attention to paragraphs 62-64 of G.W. Hogue’s Declaration and exhibits D and E attached thereto. App. Br. 25; Hogue Dec. ¶¶ 62-64, Ex’s. D and E. Exhibit D is a declaration made by William Bowlin (“Bowlin”). Bowlin characterizes Hogue’s invention as a Dual Fork Stacker including Dual Fork Stacking Arms, with independent electronic positioning and controls for each set of arms and independent electronic control of the speed and acceleration of each set of stacking arms based on the position of the arms during the course of travel. Hogue Dec. ¶ 63; Ex. D. Exhibit E is a letter allegedly made in February 2007 by Leo Campbell (“Campbell”), President of Carbotech. Campbell offers praise but characterizes Hogue’s invention as a Dual Fork Stacker with positioning and electrical/electronic controls. Hogue Dec. ¶ 64; Ex. E. Appeal 2009-006020 Reexamination Control 90/008,119 Patent 6,991,423 36 Hogue’s evidence of industry praise is not commensurate in scope with the claims since the claims on appeal do not require independent electronic positioning and controls for each set of arms or independent electronic control based on the position of the arms during the course of travel. Campbell’s characterization of Hogue’s invention is also broader than the claimed invention so as to make uncertain that the device being referred to by Campbell corresponds to the invention claimed. Based on the record before us, it has not been established that the industry praise is due to the merits of the claimed invention. Therefore, Hogue does not meet its burden of showing a nexus. Conclusion of Obviousness/Non-Obviousness We have carefully weighed and evaluated the evidence supporting obviousness and the objective evidence of non-obviousness provided by Hogue. Upon careful consideration of the evidence as a whole, and weighing it anew, the evidence supporting the conclusion of obviousness outweighs the evidence of non-obviousness. For these reasons, we sustain all of the rejections of claims 1-19 as obvious over the applied prior art. DECISION We AFFIRM the rejection of claims 1-2 and 9 under 35 U.S.C. § 102(b) as anticipated by Johansson. We AFFIRM the rejections of the following claims under 35 U.S.C. § 103(a) as unpatentable: Claims 1-2 over Rysti, in view of Johansson and DLS. Claims 1-2 and 5-8 over DLS in view of Rysti or Johansson. Claims 3-4 over Rysti in view of DLS and Larson.
