LEBOVITZ, JEFFREY B. ROBERTSON and DANIEL S. SONG, Administrative Patent Judges. SONG, Administrative Patent Judge. DECISION ON APPEAL 1 These reexamination proceedings were merged by Decision, Sua Sponte, to Merge Reexamination Proceedings, mailed July, 14, 2009. 2 Issued October 31, 2006 to Weaver et al. (hereinafter "'744 patent"). Appeal 2011-010701 Reexamination Control 95/000,465 and 90/009,377 Patent US 7,128,744 B2 2 The Patent Owner (hereinafter "Appellant") appeals under 35 U.S.C. §§ 134, 306 and 315 (2002) from a Final Rejection of claims 1-55. We have jurisdiction under 35 U.S.C. §§ 134, 306 and 315 (2002). In addition to the Appeal Brief (hereinafter "App. Br."), the Appellant also relies on Declarations of Drs. Turen and Parsons and Mr. Haag, and Exhibits therein, in support of patentability including secondary consideration evidence. The Appellant further relies on a Rebuttal Brief (hereinafter "Reb. Br.") filed in response to the Examiner's Answer, the latter which merely incorporates the Right to Appeal Notice (hereinafter "RAN"). The Requester (hereinafter "Respondent") has filed a Respondent Brief (hereinafter "Resp. Br."), and relies on the Declarations of Mr. Donoghue and Dr. Marsh in support of the Examiner's rejections. The Respondent does not cross-appeal the Examiner's refusal to adopt various proposed rejections (RAN 21), or the Examiner's withdrawal of other previously adopted rejections (RAN 24). An oral hearing with the Appellant's representative and the Respondent's representative was held before the Board of Patent Appeals and Interferences on December 7, 2011, a transcript of which will be made of record in due course. The '744 patent is presently involved in the following infringement litigation proceedings, both of which have been stayed pending the conclusion of the present reexamination proceeding (App. Br. 1): 1. Synthes (U.S.A.) v. Smith & Nephew, Inc., Civil Action No. 03- 0084 (E.D. Pa); and Appeal 2011-010701 Reexamination Control 95/000,465 and 90/009,377 Patent US 7,128,744 B2 3 2. Synthes (U.S.A.) v. G.M. Dos Reiss JR Ind. Com De Equip Medico, Civil Action No. 3:07 cv 309 (S.D. Cal.). The citations in this decision are to the record of inter partes Reexamination Control 95/000,465, including the Request for Inter partes Reexamination (hereinafter "Request"), unless otherwise indicated. We AFFIRM-IN-PART. THE INVENTION Claims 1-55 on appeal are directed to a bone plating system which is used to repair a bone fracture. Claims 1, 24 and 53 are independent claims, claim 53 being similar to claim 24. Representative independent claims 1 and 24 read as follows (App. Br., Claims App'x., emphasis added): 1. (Original) A bone plating system for improving the stability of a bone fracture in a long bone comprising: a bone plate having: an upper surface; a lower surface; a shaft portion having a width and a central longitudinal axis, the shaft portion configured and dimensioned to extend along at least a portion of a diaphysis of the bone and the lower surface of the shaft portion having a plurality of arched cut-outs extending transverse to the longitudinal axis; and a head portion that flares outward from the shaft portion so as to have a width that is greater than the width of the shaft portion, the head portion curving upward from the shaft portion and having at least three bone anchor holes, the bone anchor holes being conically tapered from the upper surface to the lower surface, the at least three bone anchor holes having at least a portion Appeal 2011-010701 Reexamination Control 95/000,465 and 90/009,377 Patent US 7,128,744 B2 4 that has a thread to engage a thread on a head of a bone anchor, wherein the head portion has only bone anchor holes having the threaded portion, the shaft portion, having a plurality of holes having at least a portion that has a thread to contact the thread on the head of a bone anchor. 24. (Original) A bone plating system for improving the stability of a bone fracture in a long bone comprising: a bone plate having: an upper surface; a lower surface; a shaft portion having a width and a central longitudinal axis, the shaft portion configured and dimensioned to extend along at least a length of a diaphysis of the bone and the lower surface of the shaft portion having a plurality of arched cut-outs extending transverse to the longitudinal axis; and a head portion having a width that is greater than the width of the shaft portion and which curves upward from the shaft portion, the head portion having a plurality of conically tapered holes having at least a portion that has a thread to contact a bone anchor, wherein the shaft portion has a plurality of conically tapered holes having at least a portion that has a thread to contact a thread on the head of a bone anchor, and the shaft portion of the bone plate has a thinner cross section in regions between the plate holes. In addition, dependent claim 32 reads as follows (App. Br., Claims App'x.): 32. (Original) The bone plating system of claim 24, wherein all of the holes located in the head portion for Appeal 2011-010701 Reexamination Control 95/000,465 and 90/009,377 Patent US 7,128,744 B2 5 receiving bone anchors have at least a portion that is threaded. THE REJECTIONS In the present appeal, there are 52 different grounds of rejection identified as Grounds 1-8, 12-31, 35-55 and 86-88 (RAN 29). The remaining Grounds 9-11, 32-34 and 56-85 proposed by the Respondent were not adopted by the Examiner (RAN 29). In the 52 different grounds of rejection, various claims are rejected under 35 U.S.C. §103(a) as obvious over various combinations of 15 prior art documents of record. In view of the high number of rejections, we do not reproduce the rejections herein. However, the 52 obviousness rejections can be categorized as follows: 1. Rejections of all claims principally based on K982222 (Grounds 1-8, 12-23) (RAN 4-7, 27); 2. Rejections of all claims principally based on Koval (Grounds 24-31, 35-55) (RAN 7-12, 28); and 3. Rejections of all claims principally based on Synthes Catalog (Grounds 86-88) (RAN 16-17)3. In addition, not all of the prior art references relied upon by the Examiner in rejecting the various claims are pertinent to the disposition of the present appeal. Instead, the dispositive issues center on the following five references: 3 These grounds of rejection were proposed in the ex parte Reexamination Control 90/009,377. Appeal 2011-010701 Reexamination Control 95/000,465 and 90/009,377 Patent US 7,128,744 B2 6 1. Collin, Surgical Instruments (1935) (catalog) (hereinafter "Collin"); 2. Koval et al., Distal Femoral Fixation, Journal of Orthopaedic Trauma (Oct. 1997) (hereinafter "Koval"); 3. Haas et al., LISS-Less Invasive Stabilization System, OP- JOURNAL, Issue 3, Volume 13, pp. 340-344 (Dec. 1997) (citations to translation) (hereinafter "Haas"); 4. Synthes, 1997 Edition (1997) (catalog) (hereinafter "Synthes Catalog"); and 5. Synthes, Synthes Condylar Buttress Plates (July 1998) (hereinafter "K98222"). ISSUES While there are 52 different grounds of rejection on appeal, the dispositive issues are few and are as follows: 1. Whether the Examiner erred in concluding that it would have been obvious to one of ordinary skill in the art to modify a condylar buttress plate having a head portion that includes unthreaded bone anchor holes as described in K982222, Koval or Synthes Catalog so as to only provide holes having a threaded portion in the head portion of the buttress plate. 2. Whether the Examiner erred in concluding that it would have been obvious to one of ordinary skill in the art to modify a condylar buttress plate as described in K982222, Koval or Synthes Catalog to provide holes in the shaft portion of the buttress plate having a threaded portion as well as non-threaded holes. Appeal 2011-010701 Reexamination Control 95/000,465 and 90/009,377 Patent US 7,128,744 B2 7 3. Whether the Examiner properly construed the claim limitation "a plurality of conically tapered holes having at least a portion that has a thread" recited in independent claims 24 and 53 to encompass a hole disclosed in Collin that includes a conically tapered portion and a partially threaded cylindrical hole portion. 4. Whether the Appellant has sufficiently established non- obviousness through evidence of commercial success. PRINCIPLES OF LAW "The combination of familiar elements according to known methods is likely to be obvious when it does no more than yield predictable results." KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398, 415-16 (2007). "[W]hen a patent claims a structure already known in the prior art that is altered by the mere substitution of one element for another known in the field, the combination must do more than yield a predictable result." Id. at 416. "If a person of ordinary skill can implement a predictable variation, §103 likely bars its patentability." Id. at 417. The Court also affirmed that "when a patent claims a structure already known in the prior art that is altered by the mere substitution of one element for another known in the field, the combination must do more than yield a predictable result." Id. at 416. In addition, "the analysis need not seek out precise teachings directed to the specific subject matter of the challenged claim, for a court can take account of the inferences and creative steps that a person of ordinary skill in the art would employ." KSR, 550 U.S. at 418. In this regard, "[a] person of Appeal 2011-010701 Reexamination Control 95/000,465 and 90/009,377 Patent US 7,128,744 B2 8 ordinary skill is also a person of ordinary creativity, not an automaton." Id. at 421. However, a "patent composed of several elements is not proved obvious merely by demonstrating that each of its elements was, independently, known in the prior art[,]" and "it can be important to identify a reason that would have prompted a person of ordinary skill in the relevant field to combine the elements in the way the claimed new invention does." Id. at 418. The Court also noted that "[t]o facilitate review, this analysis should be made explicit." KSR, 550 U.S. at 418, (citing In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006) ("[R]ejections on obviousness grounds cannot be sustained by mere conclusory statements; instead, there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness")). Further, if proposed modification would render the prior art invention being modified "inoperable for its intended purpose", then there is no suggestion or motivation to make the proposed modification. In re Gordon, 733 F.2d 900, 902 (Fed. Cir. 1984); In re Ratti, 270 F.2d 810, 813 (CCPA 1959). Any initial obviousness determination is reconsidered anew in view of the proffered evidence of nonobviousness. See In re Rinehart, 531 F.2d 1048, 1052 (CCPA 1976); In re Eli Lilly & Co., 902 F.2d 943, 945, (Fed. Cir. 1990). The scope of the "objective evidence of non-obviousness must be commensurate in scope with the claims which the evidence is offered to support." In re Tiffin, 448 F.2d 791, 792 (CCPA 1971). The objective evidence is not commensurate in scope with the claimed subject matter if the claims are unreasonably broader in scope than the scope of the objective Appeal 2011-010701 Reexamination Control 95/000,465 and 90/009,377 Patent US 7,128,744 B2 9 evidence or if the product included elements or features not recited in the claims which may be responsible for the commercial success or praise. See Joy Tech., Inc. v. Manbeck, 751 F. Supp. 225, 229-30 (D.D.C. 1990) (and cases cited therein), aff'd, 959 F.2d 226 (Fed. Cir. 1992). A "nexus" must also be established between the merits of the claimed invention and the evidence of secondary considerations in order for the evidence to be given substantial weight. See In re GPAC, Inc., 57 F.3d 1573, 1580 (Fed. Cir. 1995). If evidence of commercial success is relied upon, the Appellant must offer proof "that the sales were a direct result of the unique characteristics of the claimed invention-as opposed to other economic and commercial factors unrelated to the quality of the patented subject matter." In re Huang, 100 F.3d 135, 140 (Fed. Cir. 1996); see also Asyst Techs., Inc. v. Emtrak, Inc., 544 F.3d 1310, 1316 (Fed. Cir. 2008) ("While the evidence shows that the overall system drew praise as a solution to a felt need, there was no evidence that the success of the commercial embodiment . . . was attributable to the . . . only material difference between [the prior art] and the patented invention.") (citation omitted, emphasis added); In re Kao, 639 F.3d 1057, 1068 (Fed. Cir. 2011) ("Where the offered secondary consideration actually results from something other than what is both claimed and novel in the claim, there is no nexus to the merits of the claimed invention"). ANALYSIS Much of the relevant facts as to what the pertinent prior art discloses are not in dispute. K982222 and Koval each disclose a condylar buttress Appeal 2011-010701 Reexamination Control 95/000,465 and 90/009,377 Patent US 7,128,744 B2 10 plate that includes a head portion with holes having a threaded portion, but also includes two holes that are not threaded (K98222 Description; Koval Abstract, Discussion, Fig. 1; see also App. Br. 17-20; Resp. Br. 4-5). Synthes Catalog discloses a condylar buttress plate for Distal Femur Operations with only non-threaded holes (Synthes Catalog pg. 2a-24; see also App. Br. 11; Resp. Br. 4-5). Haas discloses a "Less Invasive Stabilization System" (hereinafter "LISS") bone plate in which all of the holes are conical and threaded to receive screws with threaded heads (Haas, pgs. 340-341, Diags. 3 and 4; see also App. Br. 20-22; Resp. Br. 6). Any factual dispute as to the scope of disclosure in the prior art is addressed in the context of addressing the above noted issues. Issue 1 The Examiner's rejections of claim 1 are based on the conclusion that it would have been obvious to one of ordinary skill in the art to modify a condylar buttress plate having a head portion with unthreaded bone anchor holes as described in K982222, Koval or Synthes Catalog so as to only include conically tapered holes having a threaded portion (see, e.g., RAN 17). The Examiner adopted the rejections as proposed and articulated by the Respondent in its requests for ex parte reexamination and inter partes reexamination with its numerous claim charts (RAN 17). For example, with respect to the rejection of claim 1 based on K982222, the Request stated: To the extent that K982222 does not disclose a head portion having at least three threaded bone anchor holes which are conically tapered, it would be obvious to one of ordinary skill in the art to modify K982222 to include a head portion that includes only threaded, conically tapered holes since such a Appeal 2011-010701 Reexamination Control 95/000,465 and 90/009,377 Patent US 7,128,744 B2 11 configuration is nothing more than one of numerous configurations one of ordinary skill would find obvious for the intended use given the known advantages of using threaded holes in the head portion of a plate. Haas, for example, discloses a bone plate that has a head portion that includes all threaded holes. "[S]crew/plate connection which is achieved by means of the outer thread of the screw head and an internal threading of the plate hole." (Figs. 3 and 4; p. 341). The plate holes of Haas are all threaded and conically tapered, therefore, the head has only threaded, conically tapered holes. It would be obvious to modify K982222 with Haas based on the advantages of locked screws as discussed in Haas (e.g., "the angularly stabile, screw/plate connection which is achieved by means of the outer thread of the screw head and an internal threading of the plate hole, thus prohibiting a varying direction the [sic] screw" (p. 341)). (Request, Exhibit E, 4; see also Request 41-42). The above reproduced rationale is representative of the adopted rejections of claim 1 based on Koval and Synthes Catalog as well (see, e.g., Request 53-54, Exhibit M, 7-8; Ex parte Reexamination Request 13-14). With respect to claim 1, the Appellant argues that there is no motivation for one of ordinary skill in the art to combine the disclosure in Haas with any of the condylar buttress plates described in K982222, Koval or Synthes Catalog because the resultant modified plate "would not have worked for its intended purpose." (App. Br. 6; see also Rebuttal Br. 3, 7). The Appellant points out that condylar buttress plates include at least two unthreaded holes in the head portion for use as "a reduction aid in reducing and setting" the bone fracture with standard bone screws so as to "allow surgeons to compress the head portion to the underlying condylar bone surface and thereby properly secure the head portion to the condylar surface." (App. Br. 6; see also Rebuttal Br. 5). The Appellant argues that if Appeal 2011-010701 Reexamination Control 95/000,465 and 90/009,377 Patent US 7,128,744 B2 12 all of the holes in the head of the condylar buttress plates are threaded and locking screws with threaded heads are used, the "capacity of the plate to function as a reduction aid" is eliminated and compression of the head portion against the condylar portion of the bone cannot be attained (App. Br. 6-7; see also Rebuttal Br. 10). The Examiner responds that the Specification of the '744 patent "expressly admits that non-locking screws (i.e. screws with unthreaded heads) can be used in threaded holes." (RAN 22, citing col. 6, ll. 49-51). However, as noted by the Appellant (App. Br. 43), the portion of the '744 patent cited by the Examiner pertains to the disclosed invention, and is not an admission. Thus, the Examiner's reliance upon it in rejecting claim 1 is misplaced. We agree with the Appellant and in our view, the modification to conventional condylar buttress plates suggested by the Examiner appears to be based on impermissible hindsight. The preponderance of the evidence of record indicates that an important function of conventional condylar buttress plates is to allow generation of compression between the plate and the bone, such compression being attained by conventional bone screws with non- threaded heads which are received through non-threaded holes (see, e.g., Decl. of Mssrs. Parsons, ¶¶ 12-18; Turen, ¶¶ 12-15; and Marsh ¶¶ 11-12). This compression function of the condylar buttress plates disclosed in K982222, Koval or Synthes Catalog undermines the articulated reason for providing only at least partially threaded, conically tapered holes in the head portion thereof. KSR, 550 U.S. at 418; In re Gordon, 733 F.2d at 902; In re Ratti, 270 F.2d at 813. Further, as discussed infra, the evidence of record is Appeal 2011-010701 Reexamination Control 95/000,465 and 90/009,377 Patent US 7,128,744 B2 13 insufficient to establish that the tapered holes disclosed in Haas are usable to impart compression between the head portion of the buttress plates. To be clear, we do not disagree with the Examiner or the Requester that the provision of threaded holes in the head portion of a bone plating system would have been desirable (see, e.g., Decl. of Marsh, ¶ 55). Indeed, the record indicates that such desirability was recognized by Bolhofner,4 as well as K98222 and Koval. However, the question with respect to claim 1 is whether it would have been obvious to then eliminate non-threaded holes in their entirety from the head portion of condylar plates to only provide at least partially threaded, conically tapered holes thereon. The evidence of development in the art in view of Bolhofner indicates that it was obvious to those of ordinary skill in the art to only thread some of the screw holes (see K98222 and Koval) supporting the Patent Owner's argument of non- obviousness. The Requester also asserts that compression may be attained using other methods and devices so that the use of non-threaded holes is not necessary and that such modified plates may still be used to treat different types of fractures (Resp. Br. 14-18; Decl. of Marsh, ¶¶ 55). The Requester further argues that the prior art does not teach away from the suggested 4 Bolhofner et al., The Results of Open Reduction and Internal Fixation of Distal Femur Fractures Using a Biologic (Indirect) Reduction Technique, Journal of Orthopaedic Trauma, Vol. 10, No. 6, pp. 372-377, 376 (1996) (hereinafter "Bolhofner"). Bolhofner is not relied upon by the Examiner in any ground of rejection. However, both the Appellant and the Requester reference Bolhofner as evidence of the art immediately prior to Koval and K982222. Appeal 2011-010701 Reexamination Control 95/000,465 and 90/009,377 Patent US 7,128,744 B2 14 modification and that there would be a reasonable expectation of success for combing the prior art as suggested (Resp. Br. 12-13). However, the Requester's arguments do not satisfactorily address why one of ordinary skill in the art would modify condylar buttress plates that already have provisions for attaining compression via the non-threaded holes so as to remove this significant functionality (see, e.g., Decl. of Turen, ¶¶ 42-45), and to further require different devices and techniques to be used for attaining the compression. In this regard, whereas providing threaded holes in the head portion would expand the application and utility of the bone plates when non-threaded holes are maintained (see, e.g., Bolhofner, pg. 376), removing the non-threaded holes altogether would not allow the modified condylar buttress plates to be used in the manner and for the purpose intended in K98222 and Koval. In this regard, the evidence of record is insufficient to establish that the tapered holes recited in claim 1 are usable to impart compression between the head portion of the buttress plates and the bone as discussed in further detail infra. In our view, the position of the Examiner and the Respondent does not appear to be based on adequate rational underpinnings. KSR, 550 U.S. at 418. In further arguing obviousness, the Respondent pointed out during the Oral Hearing that the Examiner cited to the wrong portion of the '744 patent and directed our attention (Hearing Transcript; See also Requester's Comments Sept. 17, 2010) to the discussion of the prior art therein which states: U.S. Patent No. 5,709,686 discloses a bone plate with partially threaded plate holes. The partially threaded holes allow either non-locking or locking screws to be used. Because the plate Appeal 2011-010701 Reexamination Control 95/000,465 and 90/009,377 Patent US 7,128,744 B2 15 holes are only partially threaded, the locking screws used may not be able to maintain the fixed angular relationship between the screws and the plate under physiological loads. (Col. 2, ll. 17-21). While this portion of the Specification of the '744 patent acknowledges a bone plate with partially threaded plate holes for use with non-locking or locking screws in U.S. Patent No. 5,709,686 (hereinafter "'686 patent"), we observe that claim 1 is structurally distinguished from the partially threaded plate holes of the '686 patent in that claim 1 specifically requires the bone anchor holes on the head portion to be "conically tapered from the upper surface to the lower surface." The partially threaded holes of the '686 patent that include an unthreaded conically flaring area 5 and a separate threaded straight portion 3 as disclosed therein ('686 patent, col. 2, ll. 27-29, 51-64; Figs. 1, 6-7) cannot be reasonably said to satisfy this limitation. A hole that is "conically tapered from the upper surface to the lower surface" as recited in claim 1 is only shown in the record by the threaded hole of Haas. Thus, the question remains as to whether it would have been obvious to one of ordinary skill in the art to utilize the threaded holes as disclosed in Haas when such holes are not disclosed as being used with corresponding non-locking screws that would allow for compression between the bone plate and the bone. The Respondent asserts that use of threaded, conically tapered holes is merely one of numerous configurations and that compression can still be attained with known threaded holes (Resp. Br. 19). However, we are not provided with persuasive, objective evidence establishing that partially threaded plate holes that are "conically tapered from the upper surface to the Appeal 2011-010701 Reexamination Control 95/000,465 and 90/009,377 Patent US 7,128,744 B2 16 lower surface" were one of the known hole configurations that were suitable for use with both non-locking and locking screws. The Respondent's arguments based on the fact that the use of a partially threaded plate holes for use with non-locking or locking screws was also known in both the Locking Reconstruction Plate (hereinafter "LRP") and Distal Radius Plate (hereinafter "DRP") technologies (Resp. Br. 7, 9, 19) are not persuasive. Firstly, the Examiner's adopted rejections are not predicated on either LRP or DRP technologies. In addition, both of these technologies utilize holes that are not "conically tapered from the upper surface to the lower surface" as specifically recited by claim 1 (see also, RAN 24 with respect to LRP). Thus, like the disclosure of the '686 patent, LRP and DRP technologies are structurally deficient and do not meet the claim limitation. Whereas the Requester further argues that a standard bone screw can simply be used (Resp. Br. 20), there lacks persuasive, objective evidence of such use of standard bone screws in a conical tapered hole having a threaded portion such as that disclosed in Haas. The Requester's assertion that Haas discloses a countersunk upper portion which allows for the use of standard bone screws (Resp. Br. 20) ignores the fact that the chamfering provided on the holes of Haas is very small and shallow. Hence, Haas's disclosure calls into question the Requester's assertion. In this regard, we also find persuasive the Appellant's argument based on expert testimony that a person of ordinary skill would not use conventional bone screws in the conical tapered holes of Haas due to the lack of a countersunk upper portion in the tapered holes, which would result in the head sitting high atop the plate (App. Br. 39, 42; Decl. of Turen ¶¶ 63). Appeal 2011-010701 Reexamination Control 95/000,465 and 90/009,377 Patent US 7,128,744 B2 17 In view of the above, we conclude that the rejection of claim 1 appears to be based on hindsight. Neither the Examiner nor the Respondent has sufficiently shown that it would have been obvious to one of ordinary skill in the art to eliminate non-threaded holes from the head portion of condylar plates and only provide at least partially threaded, conically tapered holes thereon. Hence, the Examiner's rejections of independent claim 1 are not sustained. Claims 2-23 ultimately depend from independent claim 1, and thus, the rejections of these claims are also reversed. The Appellant's arguments directed to patentability of claim 1 based on the limitation "the shaft portion having a plurality of holes having at least a portion that has a thread" are moot with respect to claim 1, but unpersuasive for the reasons discussed infra relative to independent claims 24 and 53. Issue 2 Independent claims 24 and 53 differ from claim 1 in that, inter alia, they merely recite a "head portion having a plurality of conically tapered holes having at least a portion that has a thread to contact a bone anchor." Thus, these claims do not require all of the holes in the head portion to be conically tapered holes with a threaded portion. The Appellant relies on the limitation requiring the shaft of the bone plate to include a plurality of threaded holes for patentability and argues that "there was no motivation in the art to replace a plurality of the DCU [non-threaded] holes in the shaft portion of the condylar buttress plates of these three primary references [K982222, Koval, Synthes Catalog] with the LISS-style locking holes of Haas." (App. Br. 7, 46). Appeal 2011-010701 Reexamination Control 95/000,465 and 90/009,377 Patent US 7,128,744 B2 18 The Examiner adopted the rejections as proposed by the Respondent (RAN 17). For example, with respect to the rejection of claim 24 based on K982222, the Request stated: To the extent that K982222 does not disclose a shaft portion having at least partially threaded holes, it would be obvious to one of ordinary skill in the art to modify K982222 to include threaded holes in the shaft since these type of holes are nothing more than one of numerous configurations one of ordinary skill would find obvious for the intended use given the known advantages of using threaded holes. Haas, for example, discloses a shaft portion with threaded holes. As discussed above, all the plate holes of Haas are threaded. It would be obvious to one of ordinary skill in the art to combine the disclosure from K982222 and the Haas Article to arrive at a plate having threaded holes in the shaft. The advantages of the threaded holes disclosed in the Hass Article, would have been well known to a person of ordinary skill in the art. Accordingly, there existed ample motivation for a person of ordinary skill in the art to improve K982222 to include threaded holes in the shaft. Thus it would have been obvious to combine the unthreaded second holes disclosed in K982222, with the threaded first holes disclosed in the Hass Article to arrive at the claimed shaft portion having threaded plate holes. (Request, Exhibit E, 32; see also Request 41-42). The Appellant refers to the arguments submitted with respect to independent claim 1 and the Appellant argues that the primary references are "designed with only unthreaded, dynamic compression unit (DCU) holes in the shaft portion. Haas does not override the explicit teachings in the primary references in this regard to use only unthreaded DCU holes, and does not suggest that the function provided by the DCU holes should be Appeal 2011-010701 Reexamination Control 95/000,465 and 90/009,377 Patent US 7,128,744 B2 19 removed or altered in any way." (App. Br. 43; see, e.g., Decl. of Parsons, ¶¶ 68, 71). We disagree with the Appellant. Firstly, the primary references do not explicitly teach the use of only unthreaded DCU holes so as to expressly teach away from use of threaded holes. Mere description of an implementation in the prior art that differs from the Appellants' claimed invention, without more, does not show that the prior art is "teaching away" from the invention claimed. 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 because such disclosure does not criticize, discredit, or otherwise discourage the solution claimed"). The mere fact that the devices of the prior art such as K982222 "features dynamic compression unit (DCU) screw holes," (App. Br. 45) does not mean that the reference is teaching that no other embodiments would be useful. While there is no explicit teaching to provide both threaded and unthreaded holes in the shaft of the bone plate, such an explicit teaching is not required to show obviousness. KSR, 550 U.S. at 418. As discussed above, the prior art of record sufficiently establishes the desirability of providing threaded holes in the head portion of a bone plating system together with unthreaded holes for compression purposes (see K98222, Koval). Whereas the Appellant argues that a person of ordinary skill would not look to the LISS technology which stabilizes a bone fracture differently and without contact between the plate and the bone (App. Br. 44- 45), the use of threaded holes with locking screws is established in the art as Appeal 2011-010701 Reexamination Control 95/000,465 and 90/009,377 Patent US 7,128,744 B2 20 being desirable to achieve an angular stabile connection, whether it is for condylar buttress plates (K98222, Koval) or for LISS type of plates (Haas). In our view, it would have been obvious to one of ordinary skill in the art that the benefit of angular stabilization offered by providing threaded holes in the head portion of the bone plate would be similarly applicable to the shaft portion of the bone plate for reasons and benefit of being angular stabile as articulated in Haas (See Haas, 340-341; see also Decl. of Marsh, ¶¶ 77, 79-80, 83). Further, we observe that the proposed modification is not to only provide threaded holes in the shaft of the prior art condylar buttress plates. Rather, the suggested modification is to provide both non-threaded and threaded holes in the shaft. Hence, the compression between the condylar buttress plate and the bone can be attained using the non-threaded holes. Accordingly, our concerns discussed supra relative to the rejection of claim 1 are not raised with respect to claims 24 and 53. The Appellant's argument with respect to the impropriety of using conventional bone screws in the conically tapered holes of Haas would not be applicable since the screws as disclosed Haas can be used in the correspondingly shaped conically tapered holes. Therefore, based on the evidence before us, it would have been obvious to one of ordinary skill in the art that by providing both unthreaded as well as at least partially threaded holes in the shaft portion of the prior art condylar buttress plates, the angular stabile connection of the screw/plate connection as taught in Haas can be attained. Similar reasoning applies to provision of a plurality of conically tapered holes with a thread portion in the head portion of the bone plate as required by these claims. With respect to the Synthes Catalog, it would have Appeal 2011-010701 Reexamination Control 95/000,465 and 90/009,377 Patent US 7,128,744 B2 21 been obvious to provide threaded holes for use with locking screws, especially in view of K982222 and Koval that already include threaded holes on the head portion. It would have also been obvious to one of ordinary skill in the art that the types of holes disclosed in Haas are entirely suitable for attaining the angular stabile connection. While the threaded holes in the head portion of K982222 and Koval may differ from the claims in that they are not conically tapered, we agree with the Examiner that the threaded holes of K992222, Koval and Haas, are all different type of threaded holes for receiving corresponding locking screws, use of any of these threaded holes would have been obvious to one of ordinary skill. In this regard, the use of the threaded holes disclosed in Haas in the head portion of K982222 or Koval is "the mere substitution of one element for another known in the field" which merely yields a predictable result. KSR, 550 U.S. at 416. Thus, for the reasons discussed, the invention of claims 24 and 53 is merely combination of elements found in the prior art which yields predictable results which would have been obvious to a person of ordinary skill who is also a person of ordinary creativity. KSR, 550 U.S. at 415-16, 421. Claim 32 which depends from claim 24 specifically recites that "all of the holes located in the head portion" have a threaded portion. The Appellant relies on the same arguments made with respect to claim 1 to contend patentability (App. Br. 8, 47-48). We reverse the Examiner's rejection of claim 32 for the reasons discussed supra with respect to claim 1. Issue 3 Appeal 2011-010701 Reexamination Control 95/000,465 and 90/009,377 Patent US 7,128,744 B2 22 The Appellant also argues that the Examiner's rejection of independent claims 24 and 53 based on K982222, Koval or Synthes Catalog in view of Collin (Grounds 12-15, 35-38; RAN 6, 9, 27) is improper because the Examiner misconstrued the limitation "a plurality of conically tapered holes having at least a portion that has a thread" to encompass holes disclosed in Collin (App. Br. 46). The Appellant argues that the claim limitation "means that in the head portion there are a plurality of holes that have a section that is conically tapered and at least a portion of that conically-tapered section is threaded." (App. Br. 46-47, emphasis added). The Examiner asserts that under the broadest reasonable interpretation, these claims "do not require the plurality of holes in the head portion of the plate be conically tapered along the entire depth of the holes." (RAN 27, emphasis in original). We do not agree with either the Appellant's construction or the Examiner's construction. The plain language of these claims requires the holes to be "conically tapered," not that the holes have a section that is conically tapered as asserted by the Appellant. In other words, the claim language with respect to the conically tapering is with respect to the hole, not a portion or section of the hole. In this regard, these claims further recite "at least a portion" of the conically tapered holes having a thread, thereby indicating that the recited tapering refers to the entirety of the hole and not just a section thereof as asserted. Thus, these claims, when properly interpreted, require the plurality of holes in the head portion of the plate be conically tapered along the entire depth of the holes and to have a portion of the conically tapered hole to be threaded. Appeal 2011-010701 Reexamination Control 95/000,465 and 90/009,377 Patent US 7,128,744 B2 23 Our construction is consistent with the Specification of the '744 patent, which in the context of threaded holes including a conical taper with threads thereon, are conically tapered along the entire depth of the holes (see, e.g., Fig. 12-18). In contrast, the Appellant does not direct us to where the Specification of the '744 patent discloses a hole that merely includes a conically tapered section having a portion that is threaded. Our construction is also is contrary to the Examiner's construction which is satisfied by a hole that merely includes a conically tapered portion such as that shown in Collin. We view such construction to be unreasonably broad in view of the claim language. Thus, as the Examiner's rejection was premised on an improper interpretation of the claims, we do not sustain the Examiner's rejections based on K98222, Koval or Synthes Catalog in view of Collin (Grounds 12-15, 35-38). Commercial Success The Appellant alleges that it has sufficiently established non- obviousness through evidence of commercial success which is set forth in the Declaration of René Haag (App. Br. 48-52). The Examiner argues that sufficient nexus has not been shown between the merits of the invention and the evidence of commercial success (RAN 30, incorporating by reference, Respondent's Comments filed September 17, 2010, pages 17-21). The Respondent further asserts that "Appellant's commercial success arguments are also deficient because the Relevant Patents include features that are not disclosed or claimed in the '744 Patent." (Resp. Br. 23). Appeal 2011-010701 Reexamination Control 95/000,465 and 90/009,377 Patent US 7,128,744 B2 24 We initially observe that the rejections of claims 1-23 and 32 that specifically recite that the head portion has only holes having a threaded portion have been reversed supra. Thus, we evaluate the evidence of commercial success in the context of independent claims 24 and 55 that are broader than claims 1-23 in that they merely require the head portion and the shaft portion to have "a plurality of conically tapered holes having at least a portion that has a thread." We reconsider the initial obviousness determination anew in view of the proffered evidence of nonobviousness. See In re Rinehart, 531 F.2d at 1052; In re Eli Lilly & Co., 902 F.2d at 945. In having so considered the evidence, we find that the Appellant has not sufficiently shown non- obviousness of claims 24 and 53 based on the evidence of commercial success. The evidence does show commercial success of the kits in which the bone plates referred to as Locking Compression Plate (hereinafter "LCP bone plates") are sold together with corresponding locking and non-locking screws, the LCP bone plates being a major component thereof (Decl. of ¶¶ 9, 10, 18, 19). However, the scope of the "objective evidence of non- obviousness must be commensurate in scope with the claims which the evidence is offered to support." In re Tiffin, 448 at 792; see also Asyst Tech., Inc., 544 F.3d at 1316. While the LCP bone plates relied upon by the Appellant may be encompassed by independent claims 24 and 53, the submitted evidence of commercial success is not commensurate with the scope of these claims for the reasons discussed infra. Firstly, we observe that the LCP bone plates relied upon by the Appellant to establish commercial success all have only threaded holes in Appeal 2011-010701 Reexamination Control 95/000,465 and 90/009,377 Patent US 7,128,744 B2 25 the head portion for receiving screws (Decl. of Haag, ¶¶ 13-16 and Exhibits A-C). However, independent claims 24 and 53 do not require all of the holes in the head portion to be conically tapered holes with a threaded portion. The evidence of commercial success does not have to be commensurate with each and every possible embodiment of an invention, however the disparity between the scope of these broader claims and the proffered evidence cannot be overlooked because this feature of providing only threaded holes on the head portion of the LCP bone plates, in conjunction with corresponding threaded and non-threaded screws of the kit, may have contributed to the commercial success. In addition, K982222 and Koval establish that providing both threaded and non-threaded holes in the head portion of a bone plate was known in the prior art and appreciated therein to be desirable. The only material difference between the prior art K982222 or Koval and the invention of independent claims 24 and 53 is the provision of both threaded and non-threaded holes on the shaft portion of the claimed invention. The evidence of record is not persuasive in establishing that the commercial success is attributable to this material difference. See Asyst Techs., Inc., 544 F.3d at 1316; In re Kao, 639 F.3d at 1068. In particular, all of the LCP bone plates upon which commercial success is based include unconventional, figure-eight shaped "Combi holes" (Decl. of Haag, Exhibit A, 3; Exhibit B, 3; Exhibit C, 3) which are not disclosed in the Specification of the '744 patent. The "Combi holes" are clearly identified in extrinsic evidence as being a "feature" that "combine a dynamic compression unit (DCU) hole with a locking screw hole. The Combi hole provides the flexibility of axial Appeal 2011-010701 Reexamination Control 95/000,465 and 90/009,377 Patent US 7,128,744 B2 26 compression and locking capability throughout the length of the plate shaft." (Decl. of Haag, Exhibit A, 2; Exhibit B, 2; Exhibit C, 2). The unique features of the "Combi holes" may have contributed to commercial success, especially considering their asserted advantageous function. Such features are not recited in claims 24 and 53, and thus would not establish a nexus between the commercial success and the merits of the claimed invention. The Appellant does not provide persuasive evidence to establish that the above noted features of the LCP bone plates relied upon as evidence did not form the basis of the commercial success in evidence. Thus, because the evidence is not commensurate with the scope of the claims, and sufficient nexus has not been established between the evidence and the claimed invention, we find no error in the Examiner's conclusion that the Appellant failed to establish non-obviousness with respect to the invention recited in claims 24 and 53. CONCLUSIONS 1. The Examiner erred in concluding that it would have been obvious to one of ordinary skill in the art to modify a condylar buttress plate having a head portion that includes unthreaded bone anchor holes as described in K982222, Koval or Synthes Catalog so as to only provide holes having a threaded portion. 2. The Examiner did not err in concluding that it would have been obvious to one of ordinary skill in the art to modify a condylar buttress plate as described in K982222, Koval or Synthes Catalog to provide holes in the shaft portion having a threaded portion as well as non-threaded holes.
