PTOL-90A (Rev. 04/07) UNITED STATES PATENT AND TRADEMARK OFFICE __________ BEFORE THE BOARD OF PATENT APPEALS AND INTERFERENCES __________ Ex parte ROBIN ASHLEY JOHN NICHOLAS __________ Appeal 2010-000806 Application 10/476,508 Technology Center 1600 __________ Decided: June 28, 2010 __________ Before CAROL A. SPIEGEL, MELANIE L. MCCOLLUM, and STEPHEN WALSH, Administrative Patent Judges. WALSH, Administrative Patent Judge. DECISION ON APPEAL This is an appeal under 35 U.S.C. § 134(a) involving claims to a protective immunogenic composition comprising an inactivated Mycoplasma bovis and a method of preventing respiratory disease in cattle. The Patent Examiner rejected the claims as anticipated and obvious. We have jurisdiction under 35 U.S.C. § 6(b). We affirm-in-part. Appeal 2010-000806 Application 10/476,508 2 STATEMENT OF THE CASE The invention concerns an immunogenic composition comprising saponin inactivated Mycoplasma bovis. Mycoplasma bovis is a primary cause of calf pneumonia, arthritis, mastitis, and eye disease. (Spec. 1, l. 19). The Specification states that “[r]ecent strains of Mycoplasma bovis are showing increased resistance to a range of antibiotics….” (Id. at 1, ll. 25- 26). According to the Specification, inactivating Mycoplasma bovis with saponin is believed to partially disrupt its cell membrane resulting in a particularly effective vaccine. (Id. at 3, l. 24 - 4, l. 1). Claims 19, 21, 22, and 24-29, which are all the pending claims, are on appeal. Claims 19 and 26 are representative and read as follows: 19. A protective immunogenic composition comprising an inactivated Mycoplasma bovis, wherein said Mycoplasma bovis is inactivated with saponin. 26. A method of preparing the immunogenic composition of Claim 19 comprising contacting Mycoplasma bovis with saponin. The Examiner rejected the claims as follows: • claims 19, 21, 22, 24, and 25 under 35 U.S.C. § 102(e) as anticipated by Hymas;1 and • claims 19, 21, 22, 24, and 25 under 35 U.S.C. § 103(a) as unpatentable over an abstract by Rosenbusch2 in view of Tola3. 1 US Patent No. 6,548,069 B2, issued to Hymas et al., Apr. 15, 2003. 2 R. Rosenbusch, “Test of an Inactivated Vaccine Against Mycoplasma bovis Respiratory Disease by Transthoracic Challenge with an Abscessing Strain,” Abstracts of the 12th Int’l Org. of Mycoplasmology Conf., Sydney, Australia 185 (July 22-28 1998). Appeal 2010-000806 Application 10/476,508 3 • claims 26-29 under 35 U.S.C. § 103(a) as unpatentable over Hymas in view of Rurangirwa.4 Claims 21, 22, and 24-29 have not been argued separately and, therefore, stand or fall with claim 19. 37 C.F.R. § 41.37(c)(1)(vii). ANTICIPATION The Issue The Examiner’s position is that Hymas disclosed a composition comprising inactivated Mycoplasma bovis, an adjuvant and a pharmaceutically acceptable carrier. (Ans. 3). The Examiner also found that Hymas disclosed that the composition can further include carriers such as wetting agents and adjuvants such as oil and water emulsions, dextran sulfate, saponin, and aluminum hydroxide. (Id.). According to the Examiner, the composition of the prior art is the same as the claimed invention given the open language of the instant claim. (Id.). Appellant contends that Hymas is not prior art under 35 U.S.C. § 102(e). (App. Br. 3). According to Appellant, the Rule 131 Declaration of Dr. Robin Ashley John Nicholas dated June 6, 2006 demonstrated an actual reduction to practice of the claimed invention prior to Hymas’ February 3, 2001 filing date. (Id.). Further, Appellant asserts that Hymas did not expressly or inherently disclose inactivating Mycoplasma bovis with saponin. (Id. at 5). 3 S. Tola et al., “Experimental vaccination against Mycoplasma agalactiae using different inactivated vaccines,” 17 Vaccine 2764-2768 (1999). 4 F. R. Rurangirwa et al., “An inactivated vaccine for contagious caprine pleuropneumonia,” 121 The Veterinary Record 397-402 (1987). Appeal 2010-000806 Application 10/476,508 4 The dispositive issue with respect to this rejection is whether the Examiner erred in concluding that the Declaration of Dr. Nicholas failed to establish that Hymas does not qualify as prior art under 35 U.S.C. § 102(e). Findings of Fact 1. Hymas filed its application on February 3, 2001. (Hymas, (22)). 2. Robin Ashley John Nicholas filed a Rule 131 Declaration signed June 6, 2006. (Decl.) 3. The Nicholas Declaration includes a copy of an agreement, Exhibit A, between Veterinary Laboratories Agency (VLA) and Akadimpex Foreign Trade Co., Ltd. (AKADIMPEX), said to represent Professor Laszlo Stipkovits at the Veterinary Medicine Research Institute of the Hungarian Academy of Sciences. (Decl. ¶ 4.) 4. The Nicholas Declaration includes a copy of a report, Exhibit B, signed by Dr. Stipkovits. (Decl. ¶ 6.) 5. The Nicholas Declaration states that “on or before February 3, 2001, the saponin-inactivated Mycoplasma bovis vaccine mentioned in the protocol attached to the agreement and described in the above referenced patent application was prepared by me, or someone under my direction and control… and sent to Dr. Stipkovits” (Decl. ¶ 5), and “Dr. Stipkovits injected calves with the saponin-inactivated Mycoplasma bovis vaccine … according to the protocol … marked Exhibit A” (id. ¶ 6). 6. Exhibit A includes “Protocol For Mycoplasma Bovis Vaccine Trial,” which bears the name Robin Nicholas VLA and date December 2000. (Decl. Exh. A.) 7. The Protocol attached to Exhibit A references “calves vaccinated Appeal 2010-000806 Application 10/476,508 5 with 2ml of 108 of saponin vaccine subcut” and “calves each inoculated with 2ml of 108 CFU of killed saponin vaccine,” among other things. (Decl. Exh. A.) 8. Dr. Nicholas declared that “the invention claimed in the present application was conceived and reduced to practice in the United Kingdom prior to February 3, 2001.” (Id. ¶ 7). 9. Declaration Exhibit A, entitled “Agreement,” states: “[s]ubject of the Agreement is to carry out certain exploratory studies (Studies) with Mycoplasma bovis strain in order to develop vaccine against this disease in calves as fully set out in the Protocol no. 1 (the protocol).” (Decl. Ex. A). 10. Declaration Exhibit A appears to bear the signatures of Dr. Nicholas and Dr. Stipkovits, both dated Jan. 25, 2001. (Id.) 11. Declaration Exhibit B is entitled “Report On study of efficacy of experimental Mycoplasma bovis vaccines for prevention of respiratory disease induce by artificial challenge of eight week old calves. (Protocol No.:Ni-MBo2).” (Decl. Ex. B). 12. Declaration Exhibit B appears to bear the signature of Dr. Stipkovits, dated Mar. 15, 2001. (Id.) 13. Exhibit B references the use of an experimental Mycoplasma bovis vaccine, but does not explain that the vaccine was saponin-inactivated. (Id.) at 3. Principles of Law A declaration may supply a missing feature from an evidentiary exhibit. See Ex Parte Ovshinsky, 10 U.S.P.Q.2d, 1075, 1076 (Bd. Pat. App. Interf. Feb. 3, 1989). Appeal 2010-000806 Application 10/476,508 6 Analysis The filing date of Hymas was February 3, 2001. (FF-1). Dr. Nicholas, the inventor, declared that the saponin-inactivated Mycoplasma bovis of the present invention was prepared by himself, or someone under his direction and control on or before February 3, 2001. (FF-5). Dr. Nicholas further declared that “the invention claimed in the present application was conceived and reduced to practice in the United Kingdom prior to February 3, 2001.” (FF-8). Dr. Nicholas referenced two exhibits in his declaration which evidenced an agreement and a protocol for developing a vaccine against the Mycoplasma bovis disease in calves. (FF-3 and 4). The Examiner found this evidence to be insufficient because the exhibits did not expressly state that the vaccine was saponin-inactivated. (Ans. 7, FF- 13). However, as Appellant has argued (App. Br. 4) a declaration may supply such a missing feature from an accompanying exhibit. See Ovshinsky, 10 U.S.P.Q.2d. at 1076. Thus, we find that Appellant has established with declaratory evidence that the Mycoplasma bovis vaccine referenced in the protocol exhibit B was saponin-inactivated Mycoplasma bovis (FF-5 and 8) and that the composition of claim 19 was, therefore, reduced to practice prior to the filing date of Hymas. Consequently, we agree with Appellant that the Examiner has not provided adequate basis for finding the declaratory evidence insufficient to antedate Hymas. Accordingly, we reverse the anticipation rejection of claims 19, 21, 22, 24, and 25. Appeal 2010-000806 Application 10/476,508 7 OBVIOUSNESS The Issues A. Rejection over Hymas and Rurangirwa The Examiner relied on the Hymas patent, as in the anticipation rejection. (Ans. 4). Appellant contends that Hymas is not valid prior art. (App. Br. 11). For the reasons explained above, we agree with Appellant that the Examiner has not provided adequate basis for finding the declaratory evidence insufficient to antedate Hymas. We will therefore reverse this rejection. B. Rejection over Rosenbusch and Tola The Examiner’s position is that Rosenbusch taught a formalin- inactivated Mycoplasma bovis vaccine. (Ans. 4). The Examiner found that Tola disclosed a study in which goats were immunized using five sets of vaccines inactivated with phenol, formalin, heat-treatment, sodium hypochlorite or saponin. (Id.). The Examiner found that Tola concluded that the saponin-inactivated vaccine was one of the preparations that provided complete protection from infection. (Id.). According to the Examiner, it would have been obvious to a person of ordinary skill in the art at the time the invention was made to prepare the vaccine disclosed in Rosenbusch by inactivating Mycoplasma bovis with saponin because Tola taught that its saponin-inactivated vaccine protected against disease. (Id.). The Examiner further reasoned that characteristics such as dosage of the inactivated Mycoplasma bovis would have been an obvious matter of optimization. (Id.). Appellant contends that the Examiner has not provided a rational underpinning or suggestion based upon the references or knowledge of those Appeal 2010-000806 Application 10/476,508 8 of ordinary skill in the art for combining Rosenbusch and Tola. (App. Br. 11). According to Appellant, Tola provides “evidence of a structural difference between inactivation with saponin as compared with inactivation with formalin.” (Id. at 9). Additionally, Appellant asserts that Mycoplasma species vary in response to inactivation, so that Tola’s inactivation of a Mycoplasma agalactiae with saponin does not suggest using saponin to inactivate the Mycoplasma bovis of Rosenbusch. (Id.). Appellant further asserts that “it is highly unpredictable whether using saponin to inactivate mycoplasma species will generate a protective immunogenic composition [because] saponin-inactivation yields unpredictable results within species of mycoplasma.” (Id. at 10). Therefore, Appellant asserts that it would not have been obvious to try using saponin as the inactivation agent for the Mycoplasma bovis disclosed by Rosenbusch. (Id.). The issue with respect to this rejection is whether it would have been obvious to a person of ordinary skill in the art at the time of the invention to inactivate the Mycoplasma bovis disclosed in Rosenbusch with saponin, a mycoplasma inactivation agent disclosed in Tola, to provide an effective Mycoplasma bovis vaccine. Additional Findings of Fact 14. Rosenbusch is a journal article describing the preparation and test of an inactivated vaccine against Mycoplasma bovis respiratory infection. (Rosenbusch, Abstract). 15. Rosenbusch disclosed that the Mycoplasma bovis was inactivated with formalin. (Id.). 16. Tola is a journal article describing experimental vaccination against Appeal 2010-000806 Application 10/476,508 9 Mycoplasma agalactiae using different inactivated vaccines. (Tola, title). 17. Tola described preparing five sets of vaccines using Mycoplasma agalactiae inactivated with phenol (1), formalin (2), heat-treatment (3), sodium hypochlorite (4) and saponin (5). (Id. at Abstract). 18. Tola disclosed inoculating five groups of ewes (sheep) with the inactivated Mycoplasma agalactiae. (Id.). 19. Tola concluded that the ewes vaccinated with Mycoplasma agalactiae inactivated with either phenol or saponin resisted experimental challenge suggesting that these two vaccines “guarantee complete protection from M. agalactiae infection.” (Id. at 2768). 20. Tola taught that the suitability of saponin as adjuvant was known in the art and that “in mycoplasmas, its adjuvant effect combines with inactivation. This eliminates the problems of mixing the inoculation dose and the toxicity caused by separate adjuvants.” (Id.). Principles of Law When a claim is to a combination that “simply arranges old elements with each performing the same function it had been know to perform’ and yields not more than one would expect from such an arrangement, the combination is obvious.” KSR Int’l Co. v. Teleflex, Inc., 550 U.S. 398, 417 (2007), quoting Sakraida v. AG Pro, Inc., 425 U.S. 273, 282 (1976). Obvious variants of prior art teachings are themselves part of the public domain. In re Translogic Tech., Inc., 504 F.3d 1249, 1259 (Fed. Cir. 2007). Discovery of an optimum formulation by selecting one of a number of known compounds in a limited class of compounds is usually obvious. See Pfizer, Inc. v. Apotex, Inc., 480 F.3d 1348, 1368 (Fed. Cir. 2007). Appeal 2010-000806 Application 10/476,508 10 Analysis of the Rejection over Rosenbusch and Tola We are not persuaded by Appellants’ arguments that it would not have been obvious to a person of ordinary skill in the art at the time the invention was made to use saponin to inactivate the Mycoplasma bovis disclosed in Rosenbusch to provide an effective Mycoplasma bovis vaccine. Tola disclosed that it was known in the art to inactivate mycoplasmas with saponin. Tola further disclosed that the suitability of using saponin as an adjuvant was also known in the art. To this end, Tola explained that in mycoplasmas, the adjuvant effect of saponin combines with its inactivation and therefore eliminates the problems of mixing the inoculation dose and the toxicity caused by separate adjuvants. (FF-20). Thus, Tola described an advantage of using saponin as an inactivation agent in “mycoplasmas,” and did not limit this teaching to M. agalactiae. (Id.). For these reasons, we find that Tola’s disclosure would have suggested to a person of ordinary skill in the art at the time of the invention selecting saponin to inactivate a mycoplasma, including Mycoplasma bovis, to provide an effective Mycoplasma vaccine. See KSR, 550 U.S. at 417; Translogic Tech., 504 F.3d at 1259. The obviousness of this combination is not negated by the fact that structural differences may exist between inactivation with saponin as compared with inactivation with formalin. Nor is obviousness negated by the fact that mycoplasma species vary in response to inactivation. “[T]he question is whether there is something in the prior art as a whole to suggest the desirability, and thus the obviousness, of making the combination,” not whether there is something in the prior art as a whole to suggest that the Appeal 2010-000806 Application 10/476,508 11 combination is the most desirable combination available.” In re Fulton, 391 F.3d 1195, 1200 (Fed. Cir. 2004). Moreover, Tola disclosed only four chemical inactivation agents (FF- 17), only one of which was used in Rosenbusch (FF-15). Selecting any of the remaining three disclosed agents known to be used to inactivate mycoplasmas would have been nothing more than routine optimization. See Pfizer, 480 F.3d at 1368. Consequently, we find that the evidence as a whole supports the Examiner’s position that it would have been obvious to a person of ordinary skill in the art at the time the invention was made to inactivate the Mycoplasma bovis of Rosenbusch with saponin, as taught by Tola, to provide an effective Mycoplasma bovis vaccine. Accordingly, we affirm the obviousness rejections of claims 19, 21, 22, 24, and 25 over Rosenbusch in view of Tola. CONCLUSIONS OF LAW The Examiner erred in concluding that the Appellants’ declaratory evidence failed to establish that Hymas is not prior art for the 102(e) and 103(a) rejections. It would have been obvious to a person of ordinary skill in the art at the time of the invention to inactivate the Mycoplasma bovis disclosed in Rosenbusch with saponin, a mycoplasma inactivation agent disclosed in Tola, to provide an effective Mycoplasma bovis vaccine.
