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 2010-005881 Reexamination Control 90/008,968 Patent 7,201,554 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 2010-005881 Reexamination Control 90/008,968 Patent 7,201,554 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 7-24. We have jurisdiction under 35 U.S.C. §§ 134(b) and 306. We AFFIRM-IN-PART. 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 20 Dec. 2007). The current appeal is related to Appeal No. 2009-006020, Reexamination Control 90/008,119, Patent No. 6,991,423 which is decided concurrently with the present appeal. The ‘554 patent issued with 20 claims. Hogue added claims 21-24 and amended claims 1, 4, 6-9, 12-15 and 18-19. Claims 1-6 have been allowed. The Disclosed Invention Hogue’s patented invention is related to a machine and method for stacking lumber into packages. Col. 1, ll. 13-19. The subject matter of the appealed claims is illustrated by claim 21 (underlining removed, italics added for emphasis), which defines the invention as: A material stacker, comprising: a frame; a first plurality of stacking arms arranged along the frame; a second plurality of stacking arms arranged along the frame; one or more first electrically-controlled positioners configured to position the first plurality of stacking arms in a horizontal relationship with respect to the frame; Appeal 2010-005881 Reexamination Control 90/008,968 Patent 7,201,554 3 one or more second electrically-controlled positioners configured to position the second plurality of stacking arms in a horizontal relationship with respect to the frame; and an electronic control system configured to independently control the operation of the first and second electrically- controlled positioners to operate the stacker, wherein the electronic control system is configured to control the speed, position, and acceleration of the stacking arms through the positioners based on a horizontal position of the stacking arms by sending separate signals to the first and second electrically- controlled positioners. The Examiner relies on the following prior art references: Rysti 4,201,506 May 06, 1980 Johansson 4,290,723 Sep. 22, 1981 Delta Lumber Stacker Application Note (“DLS”) Apr. 07, 1998 Hogue appeals the following rejections: Claims 7-9 and 15-20 under 35 U.S.C. § 103(a) as unpatentable over Rysti in view of DLS; Claims 10-14 and 21-24 under 35 U.S.C. § 103(a) as unpatentable over Rysti in view of Johansson and DLS; and Claims 15-20 under 35 U.S.C. § 305 as unpatentable for violating the prohibition against enlargement of the scope of a patent claim under reexamination proceeding. ISSUES Has the Examiner erred in determining that claims 15-20 enlarge the scope of an original issued claim of the ‘554 patent under reexamination? Has the Examiner erred in finding that the applied prior art describes an electronic control system configured to independently control the first and second electrically-controlled horizontal positioners? Appeal 2010-005881 Reexamination Control 90/008,968 Patent 7,201,554 4 FINDINGS OF FACT 1. Hogue amended claim 15 of Patent 7,201,554 as follows (insertions underlined, subtractions [bracketed]): A method of stacking material in a stacking device, comprising: electronically controlling the speed and positioning of one or more first linear positioning devices to control the horizontal movement of a first set of stacking arms; electronically controlling the speed and positioning of one or more second linear positioning devices to control the horizontal movement of a second set of stacking arms; electronically controlling the speed and positioning of one or more linear positioning devices to control the vertical movement of the stacking arms; determining the horizontal position of the stacking arms by using one or more position monitoring devices; and controlling the vertical movement of [each of] the stacking arms based on [a] the horizontal position of [that stacking arm] the stacking arms. Rysti 2. 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. Appeal 2010-005881 Reexamination Control 90/008,968 Patent 7,201,554 5 Rysti’s figure 9 is below: Figure 9 depicts a plan view of the lumber stacker. 3. Central pair of lifting arms [36] are supported on a central carriage [68] and moved between extended and retracted positions by endless chains [102] and vertically raised and lowered by hydraulic cylinders [78], [80]. 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. 4. 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]. Col. 8, l. 56-col. 9, l. 48; col. 10, ll. 4-22; fig. 10. Johansson 1. Johansson describes, referring to Johansson’s figure 1 reproduced below [numbers from figure 1 inserted], a timber package arranger including a feed conveyor [1] and two individually movable carrier planes [5], [6]. Col. 1, l. 59-col. 2, l. 7. Appeal 2010-005881 Reexamination Control 90/008,968 Patent 7,201,554 6 Johansson’s figure 1 is below: Figure 1 depicts a timber package arranger. 2. The carrier planes [5], [6] act consecutively one after another with each acting as both a layer assembler and transfer device and move cyclically by control of the programmed control unit. Col. 2, ll. 4-10. 3. One of the carrier planes constitutes a continuation of the conveyor feed path for assembling the layer of lumber while the other carrier plane transfers the layer of lumber to the lumber package [7] on the stacking table [8]. Col. 1, l. 59-col. 2, l. 20; claim 1. 4. One of the carrier planes is always in a phase of its cyclic movement that constitutes a continuation of the feed conveyor [1] for receiving the timber pieces from the conveyor [1]. Abs.; claim 1. 5. Johansson describes, referring to Johansson’s figure 2 reproduced below [numbers from figure 2 inserted], that carrier plane [5] includes a plurality of fingers [9] each movable along a guide [11] with each of the plurality of fingers [9] and supported on its respective guide [11], by a carriage [12]. Col. 2, ll. 21-28. Appeal 2010-005881 Reexamination Control 90/008,968 Patent 7,201,554 7 Johansson’s figure 2 is below: Figure 2 depicts a top view of a portion of the timber package arranger. 6. In order to cause the carriages [12], and thereby the fingers [9] of carrier plane [5] to move along the guides [11], the carriages [12] are each connected by a link [15] with a drive mechanism [16] comprising an endless chain [17] provided about sprockets [18], one of which is stationary on a drive shaft [19]. Col. 2, ll. 27-33. 7. The drive shaft [19], is common to all drive mechanisms [16] for the carrier plane [5], thereby the fingers [9] of carrier plane [5] are moved synchronously. Col. 2, ll. 33-36. 8. For lifting and lowering the carrier plane [5], the guides [11] are pivotal about a common support point [10] by piston-cylinder means [20], one for each guide [11] that are driven synchronously to maintain the fingers [9] of the carrier plane [5] on the same level. Col. 2, ll. 36-39, 43-47. 9. The carrier plane [6] is similar to the carrier plane [5] and is driven in the same manner. Col. 2, ll. 47-55. 10. The advancing movement of the carrier planes [5], [6] during assembly of a timber package layer [21] from the feed conveyor [1] Appeal 2010-005881 Reexamination Control 90/008,968 Patent 7,201,554 8 can take place continuously or in steps and is controlled by the programmed control unit in agreement with the speed of the feed conveyor. Col. 3, ll. 26-48; claims 4-5. DLS 11. 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 12. The forks are mounted on a carriage that is moved back and forth by a hydraulic cylinder and raised and lowered by a hydraulic cylinder mounted on the carriage. P. 2, ¶ 7. PRINCIPLES OF LAW In accordance with 35 USC § 305, a proposed amended claim enlarging the scope of a patent claim will not be permitted in a reexamination proceeding. A claim of a reexamination application will be broader in scope than the patent claims if it contains within its scope any conceivable apparatus or process which would not have infringed the original patent. In re Freeman, 30 F.3d 1459, 1464 (Fed. Cir. 1994). An amended claim that is broader than the patent claims in any respect is considered to be broader than the patent claims even if it may be narrower in Appeal 2010-005881 Reexamination Control 90/008,968 Patent 7,201,554 9 other respects. Id. The issue of whether an amendment enlarges the scope of a claim is a matter of claim construction. Id. The initial burden is on the examiner to establish a prima facie case of unpatentability. In re Oetiker, 977 F.2d 1443, 1445 (Fed. Cir. 1992). There must be a factual basis to support a conclusion of obviousness. In re Warner, 379 F.2d 1011, 1017 (CCPA 1967) (Deficiencies in the factual basis can not be supplied by resorting to speculation, assumptions and hindsight reconstruction). A conclusion of obviousness requires an accounting for all of the limitations in a claim. CFMT, Inc. v. Yieldup Int’l. Corp., 349 F.3d 1333, 1342 (Fed. Cir. 2003). ANALYSIS Claim Scope Enlargement under 35 USC § 305 Hogue amended the last clause of independent claim 15 of Patent 7,201,554 from “controlling the vertical movement of each of the stacking arms based on a horizontal position of that stacking arm” to “controlling the vertical movement of the stacking arms based on the horizontal position of the stacking arms.” In rejecting claims 15-20 under 35 U.S.C. § 305, the Examiner determined that amended claim 15 is broader than original claim 15 because amended claim 15 includes controlling the stacking arms together instead of controlling the stacking arms individually as required by original claim 15. Ans. 7, 16. The Examiner further determined that the amended claim 15 contains a process, i.e., common control, which would not have infringed the original patent. Ans. 16. Appeal 2010-005881 Reexamination Control 90/008,968 Patent 7,201,554 10 We agree with the Examiner. We understand the Examiner as having determined that amended claim 15 is broader in scope since it permits both commonly controlling the movement of the stacking arms and individually controlling the movement of the stacking arms, while patent claim 15 requires individually controlling the movement of each one of the stacking arms. Hogue’s argument that requiring common movement is more restrictive than permitting individual movement (Br. 38) is misplaced. The Examiner determined the opposite - that amended claim 15 permits common control while patent claim 15 requires individual control. Hogue does not otherwise challenge the examiner’s findings and determination regarding the scope of the original patent claim 15 and the amended patent claim 15. The Examiner’s findings and determinations in that regard are reasonable and Hogue has failed to sufficiently demonstrate otherwise. Next, Hogue argues that, even assuming amended claim 15 is broader than original claim 15, amended claim 15 is not broader than other original claims; namely claims 3, 13 and 22. Br. 38-39. Specifically, Hogue argues that “controlling the vertical movement of the stacking arms based on the horizontal position of the stacking arms” of amended claim 15 is nearly identical to the limitation found in original claim 3 and similar to the limitations found in claims 13 and 22. Br. 38-39. Hogue’s arguments directed to claim 22 are not persuasive since claim 22 is not an original patent claim. Moreover, Hogue’s arguments with respect to original claims 3 and 13 are misplaced since they are based on an incorrect comparison of claims. Original patent claim 3 ultimately depends Appeal 2010-005881 Reexamination Control 90/008,968 Patent 7,201,554 11 from original independent claim 1 and original patent claim 13 ultimately depends from original patent independent claim 10. Both original claim 3 and original claim 13 are apparatus claims and narrower in scope than original patent claim 15 and amended claim 15, which are both method claims. It would be of no consequence to compare amended method claim 15 to original apparatus claims 3 and 13 of the patent, since the scope of amended claim 15, like original patent claim 15, is necessarily different in scope than original patent claims 3 and 13. The comparison must be made between an original patent claim that is closest to the amended claim 15. Claim 15 of the patent is the appropriate basis of comparison with amended claim 15. Hogue also argues that the scope of amended claim 15 is narrower than the original claims since some of the original claims did not require control of the vertical movement. Br. 39. Hogue’s arguments are misplaced because an amended claim that is broader than the patent claims in any respect is considered to be broader than the patent claims even if it may be narrower in other respects. Freeman, 30 F.3d at 1464. For all these reasons, we sustain the Examiner’s rejection of claims 15-20 as unpatentable for enlarging the scope of a patent claim under reexamination proceeding. Appeal 2010-005881 Reexamination Control 90/008,968 Patent 7,201,554 12 Obviousness of claims 10-14 and 21-24 over Rysti, Johansson and DLS2 Independent claim 21 is representative of the group and recites (disputed limitations in italics): “one or more first electrically-controlled positioners configured to position the first plurality of stacking arms in a horizontal relationship . . . one or more second electrically-controlled positioners configured to position the second plurality of stacking arms in a horizontal relationship . . . ; and an electronic control system configured to independently control the operation of the first and second electrically- controlled positioners . . . .” The Examiner finds that Rysti describes a lumber stacker including first and second sets of stacking arms [36], [36a], [36b], horizontal positioners [68], [122], [124] and vertical positioners [78], [80], [142], [144]. Ans. 5, 8; see col. 6, l. 62-col. 10, l. 48; figs. 8-11. The Examiner does not rely on Rysti for describing an electronic control system. Instead, the Examiner finds that Johansson and DLS suggest using an electronic control system which provides the advantage of automating the process with independent, precise control of the speed, acceleration, and position of the arms. Ans. 5, 8. Johansson describes a timber package arranger that includes a feed conveyor and independently movable carrier planes [5], [6] that are moved cyclically by control of a programmed control unit. Col. 1, l. 59-col. 2, l. 7. The carrier planes [5], [6] act consecutively after one another with each 2 Hogue and the Examiner disagree about whether DLS qualifies as prior art. App. Br. 7, 9-11; Ans. 8-9. We need not resolve the issue, since even assuming DLS is prior art, we do not sustain the Examiner’s rejection of claims 10-14 and 21-24 based on Rysti, Johansson and DLS. Appeal 2010-005881 Reexamination Control 90/008,968 Patent 7,201,554 13 carrier plane acting as both a layer assembler and a transfer device. Col. 2, ll. 4-10. One of the carrier planes [5], [6] is always in a phase of its cyclic movement to constitute a continuation of the feed conveyor [1] for receiving timber pieces. Abs.; col. 1, l. 59-col. 2, l. 20; claim 1. Carrier plane [5] includes a plurality of fingers [9] each movable along a guide [11] with each of the plurality of fingers [9] supported on its respective guide [11] by a carriage [12]. Col. 2, ll. 21-27. The carriages [12] are each connected with a drive mechanism [16] comprising a common drive shaft [19] to move the carriages [12] and fingers [9] of carrier plane [5] synchronously. Col. 2, ll. 27-37. Similar to carrier plane [5], carrier plane [6] includes a plurality of fingers [9’] guides [11’] and carriages [12’] connected with a drive mechanism [16’] (not shown in figure 1) comprising a common drive shaft [19’] that moves the carriages [12’] and fingers [9’] of carrier plane [6] synchronously. Col. 2, ll. 21-37, 47-55. DLS describes a lumber stacker with a single set of forks mounted on a carriage that is moved back and forth (i.e., horizontally) by a hydraulic cylinder and raised and lowered by a hydraulic cylinder mounted on the carriage. P. 2, ¶ 7; DLS’ figure. The Examiner finds that Johansson describes separate horizontal positioners (i.e., drive shafts [19], [19’]) and controllers (i.e., drive mechanisms [16], [16’]) that are independent controllers of the positioners since they are separate. Ans. 6, 8, 10. The Examiner also finds that DLS teaches that different positioners are controlled independently since each hydraulic cylinder can be independently controlled. Ans. 10, citing DLS pp. 3-4. The Examiner concluded that it would have been obvious to one with Appeal 2010-005881 Reexamination Control 90/008,968 Patent 7,201,554 14 ordinary skill in the art at the time the invention was made to modify Rysti’s invention to include an electronic control system as suggested by Johansson and DLS for the advantage of automating the process with independent, precise control of the speed, acceleration and position of the arms. Ans. 5, 8. Hogue argues that neither Johansson nor DLS teach an electronic control system configured to independently control the first and second horizontal positioners. Br. 14-15. We agree. There is an insufficient factual basis for concluding that the claimed invention would have been obvious. Neither Johansson nor DLS account for the claim limitations left unaddressed by Rysti; specifically, an electronic control system configured to independently control the first and second horizontal positioners. Although it may be possible for Johansson’s drive mechanisms [16], [16’] to independently control the drive shafts [19], [19'] (i.e., horizontal positioners) due to the physical separation of the respective drive mechanisms [16] and drive shafts [19], Johansson’s description does not suggest an electronic control system configured to independently control the horizontal postioners (i.e., drive shafts [19], [19]). Each of Johansson’s drive mechanisms [16], [16’] are a mechanical device comprising an endless chain [17] provided about sprockets [18]. Col. 2, ll. 27-33. Mechanical devices which are physically separate from one another do not necessarily suggest an electronic control system configured to independently control multiple horizontal postioners. Johansson also describes a programmed control unit, but the Examiner does not direct us to, and we can not find, where Johansson describes, or suggests, that the programmed control unit is Appeal 2010-005881 Reexamination Control 90/008,968 Patent 7,201,554 15 configured to independently control the drive shafts [19], [19'] (i.e., horizontal positioners). DLS also does not describe an electronic control system configured to independently control the first and second horizontal positioners. The Examiner does not direct us to, and we can not find, where DLS describes or suggests an electronic control unit configured to independently control the first and second horizontal positioners. The Examiner acknowledges that DLS does not describe multiple horizontal positioners. Ans. 10. In light of this, the significance of DLS is unclear. DLS’ description of controlling the horizontal and vertical movement of the forks each with a corresponding hydraulic cylinder does not suggest an electronic control system configured to independently control first and second horizontal positioners when DLS does not describe more than one horizontal positioner. As applied by the Examiner, Rysti, DLS and Johansson, alone or in combination, do not account for all the claim limitations and provide a sufficient factual basis to conclude that the claimed invention would have been obvious. For all these reasons we do not sustain the Examiner’s rejection of claims 10-14 and 21-24 as obvious over Rysti in view of Johansson and DLS. Obviousness of claims 7-9 over Rysti in view of DLS Independent claim 7 is similar to independent claim 21 and recites: “an electronic control system configured to independently control each of the plurality of electrically-controlled horizontal positioners . . . .” Since claim 7 includes limitations that are nearly identical to the disputed limitations of claim 21, for the same reasons as those addressing claims 10- Appeal 2010-005881 Reexamination Control 90/008,968 Patent 7,201,554 16 14 and 21-24, we do not sustain the Examiner’s rejection of claims 7-9 as obvious over Rysti in view of DLS. Obviousness of claims 15-20 over Rysti in view of DLS Affirmance of the Examiner’s rejection of claims 15-20 under 35 U.S.C. § 305 makes it unnecessary to reach the obviousness rejection of claims 15-20 over Rysti in view of DLS. Cf. In re Gleave, 560 F.3d 1331, 1338 (Fed. Cir. 2009)(not reaching obviousness after finding of anticipation). DECISION We AFFIRM the rejection of claims 15-20 under 35 U.S.C. § 305 as unpatentable. We REVERSE the rejection of claims 7-9 under 35 U.S.C. § 103(a) as unpatentable over Rysti in view of DLS. We REVERSE the rejection of claims 10-14 and 21-24 under 35 U.S.C. § 103(a) as unpatentable over Rysti in view of Johansson and DLS. TIME PERIOD Requests for extensions of time in this ex parte reexamination proceeding are governed by 37 C.F.R. § 1.550(c). See 37 C.F.R. § 41.50(f).
