Resp. 10. 1 In addition to other changes to Title 35, the AIA introduced amendments to 35 U.S.C. § 102. Because Patent Owner concedes that the ’725 application “contains, or contained at any time, a claim to a claimed invention that has an effective filing date on or after March 16, 2013” (Ex. 1022), the AIA version of § 102 applies to the ’109 patent.

Petitioner did not. Pet. 23– 24. Nor does Petitioner’s declarant offer testimony that could support such a showing. See Ex. 1003 ¶50 (“I have been asked to provide my opinions as to the state of the art in this field for purposes of determining what the inventors disclosed as their invention as of December 10, 2013.”), ¶51 (“Whenever I offer an opinion in this declaration about the knowledge of a POSA, the manner in which a POSA would have understood the claims of the ’109 patent or its description, the manner in which a POSA would have understood the prior art, or what a POSA would have been led to do based on the prior art, I am referencing the December 10, 2013 timeframe.”). Although the ’420 application is essentially identical to the ’767 application, the person of ordinary skill in 2013 is not the same as in 2023.

“Nevertheless, we determine that the contrary evidence Petitioner has cited suffices to establish a reasonable likelihood of success at this preliminary stage of the proceeding.

We likewise note Dr. Jain’s testimony that such artisan would have recognized Tokunaga’s conclusion, regarding “immunological and biochemical properties” of Factor C proteins of the two different horseshoe crab species, to be “based on only gross biophysical-biochemical properties” that are not “granular enough” to predict functional properties such as residual activity in presence of specific ions.

Evid. 801(c) (defining hearsay as a statement, not made at the current trial or hearing, “offer[ed] in evidence to prove the truth of the matter asserted”), with Fed. R. Evid. 801(d)(2) (excluding from hearsay statement offered against an opposing party where statement was made by “a person whom the party authorized to make a statement on the subject” or by a “party’s agent or employee on a matter within the scope of that relationship and while it existed”). Nevertheless, as discussed above, Petitioner has provided contrary evidence, including statements from Patent Owner’s patent application, suggesting that, “due to the various differences and diversity of biomolecules depending on the genus and species of the horseshoe crab,” it had not been possible “to accurately determine the full-length sequence structure, expression, and function of [Limulus] proteins and genes using conventional methods” more than 20 years after complete gene and amino sequences from two Tachypleus horseshoe crab species had been reported. Pet. 35 (citing, e.g., Ex. 1005 ¶¶ 12–17). Thus, even if we were to take the Frohman Declaration into account, we find that Petitioner has established a reasonable likelihood 28 of success that the ’767 application disclosures did not enable an ordinarily skilled artisan to make and use the invention of the challenged claim without undue experimentation. Furthermore, assuming that the disclosures in ’767 application would have enabled an ordinarily skilled artisan to express recombinant Limulus polyphemus Factor C protein in HEK293, we find Petitioner has established, sufficient for purposes of institution, that the disclosures do not enable an ordinarily skilled artisan to make such a protein exhibiting the “full scope” of the claimed residual activity, without undue experimentation. Patent Owner cites to disclosures in the ’767 application that (1) describe how to produce recombinant Factor C in HEK293 cells and measure residual activity, (2) suggest “Factor C expressed in mammalian cells can have low susceptibility to activity inhibition by ions,” and (3) provide examples where residual activity met the required minimum. Prelim. Resp. 26–27, 32–34. Nevertheless, whether an ordinarily skilled artisan would have been able to make, based on these disclosures and without undue experimentation, a recombinant Factor C protein having residual activity encompassed by claim 21 but higher — even significantly higher — than that achieved in the example, is a fact intensive issue that would benefit from further development during trial.15 See, e.g., In re” slip op. at 28

“At this stage of the proceedings, neither Petitioner’s nor Patent Owner’s proffered definitions of the level of skill appear appropriate. Petitioner’s proposal requires as little as a bachelor’s degree in organic chemistry and two years of experience as a laboratory technician working on development of molecules with targeted biological activity, and an ambiguous “understanding” of certain processes. Patent Owner’s proposal, other the other hand, requires multiple years of both formal training and actual, practical experience in highly specialized fields that involve detection of optical or radiolabeled compounds and use of molecular imaging techniques such as PET and SPECT. For the purposes of this decision, on the record at this time, we find that a POSA would have had a Ph.D. in chemistry, biochemistry, or a comparable field or an M.D., and at least four years of experience in chemical synthesis of compounds that may be used to target biologically-significant tissues. This definition appears consistent with the level of skill shown in the prior art references of record. See Daiichi Sankyo Co. v. Apotex, Inc., 501 F.3d 1254, 1256 (Fed. Cir. 2007). The parties will have the opportunity to cross-examine Dr. Martin and Dr. VanBrocklin in this proceeding to develop a full record for us to determine the weight that each expert’s testimony should be given.

“c) Analysis On the present record, we find that “low molecular weight” is not limited to Patent Owner’s proposed “from about 50 Daltons to about 1,500 Daltons.” The cited evidence relied on in the Pomper Declaration all concerns metabolomics and metabolites, and we find no reason that even a vague definition of metabolites applies to the claimed compounds. See Ex. 1002, ¶ 102. Moreover, the uncontested fact that several of the B moieties alone—without the A moiety or L linker—specifically identified in the ’201 patent fall outside of Patent Owner’s proposed definition is persuasive (see id., ¶ 103), as we normally do not interpret claim terms in a way that excludes examples disclosed in the specification. See, e.g., Verizon Servs. Corp. v. Vonage Holdings Corp., 503 F.3d 1295, 1305 (Fed. Cir. 2007) (rejecting proposed claim interpretation that would exclude disclosed examples in the specification). In addition, the opinion stated in the Pomper Declaration that “the term of ‘low molecular weight’ is well accepted in the chemical arts’” and the declarant “recognize[s] that low molecular weight compounds would have a molecular weight of typically form about 50 Daltons to about 1,500 Daltons” is offered by a co-inventor. We, as factfinder, have discretion to weigh the credibility of expert witnesses and to give each item of evidence such weight as appropriate. See In re Am. Acad. of Sci. Tech Ctr., 367 F.3d 1359, 1368 (Fed. Cir. 2004) (“[T]he Board is entitled to weigh the declarations and conclude that the lack of factual corroboration warrants discounting the opinions expressed in the declarations.”). In this case, we find that the published references on metabolites do not support the opinion. In re Am. Acad. of Sci. Tech Ctr., 367 F.3d at 1368 (Fed. Cir. 2004) (“[T]he Board is entitled to weigh the declarations and conclude that the lack of factual corroboration warrants discounting the opinions expressed in the declarations.”) The Pomper reference (Ex. 1006) also uses the term “low molecular weight”—without further characterization of the term—and is uninformative as to the meaning of the term. See Ex. 2002, ¶ 60; Ex. 1006, ¶ 12. The table giving the molecular weight of a “selection of compounds disclosed by Pomper” (see Ex. 2002, ¶ 62) is not persuasive in defining “low molecular weight,” as it does not explain how those included were “selected” and does not include molecular weights for all of the examples.7 In addition, Patent Owner’s definition does not appear to apply to all claimed compounds.8 7 At least one of the examples (SRV73) not included in the table appears to have a molecular weight well over “about 1,500 Daltons.” 8 See, e.g., claim 113 of Ex. 1006.

Patent Owner’s representation that “Jansen I provides ‘the following definitions’ stating that ‘alkyls groups of this invention comprise from 1 to 6 carbon atoms’” is inaccurate. See Prelim.

Generally, alkyl groups of this invention comprise from 1 to 6 carbon atoms. Alkyl groups may be linear or branched and may be substituted as indicated herein. When a subscript is used herein following a carbon atom, the subscript refers to the number of carbon atoms that the named group may contain. Ex. 1007, 22:16–23 (emphasis added).

“Based on our review of the record, we find that Petitioner has not shown persuasively that the Examiner did not consider the same or substantially the same art that Petitioner relies upon for its obviousness challenges. Petitioner’s grounds primarily rely on three different “May” references, only one of which the Examiner considered during prosecution, i.e., the May Article. The additional primary references relied upon by Petitioner are the May Thesis, which provides a more detailed disclosure than the May Article, and the May Abstract, which provides less detail than the May Article, in terms of the HS2, HS3, and HS4 fragments used to generate the disclosed TNS9 vector. Those differences are only material with respect to whether each reference discloses the fragments as recited in independent claim 1, or renders those fragments obvious. As discussed in Section II.D.2., however, we determine that the May Thesis is not prior art. 11 The ’221 application claims priority to provisional application no. 60/301,861 (Ex. 1034) (“the ’861 provisional application”), filed June 29, 2001, and provisional application no. 60/302,852 (Ex. 1035) (“the ’852 provisional application”), filed on July 2, 2001, referred to, collectively, as “the provisional applications,” “the provisionals” and “the Provisionals.” Article, but in less detail, the May Abstract may be considered cumulative to the May Article. Because the May Thesis provides more explicit details regarding the fragments disclosed in the May Article, it may not be considered to be cumulative to the May Article. However, as discussed in Section II.D.2., we determine that the May Thesis is not prior art. When considering the extent of the overlap between the arguments made during examination and the manner in which Petitioner relies on the May Article or Patent Owner distinguishes the May Article, we note that Patent Owner alleged during prosecution and here that the May Article is not prior art for a number of reasons, including that it is the work of the inventors and that it was published one year or less before the priority date asserted by Patent Owner for the challenged claims. We note also that Petitioner contends that the challenged claims are not entitled to the priority date asserted by Patent Owner, and recognized by the Examiner. Based on the foregoing, we conclude that substantially the same prior art that Petitioner relies upon was previously presented to the Examiner during prosecution.

Eli Lilly & Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010). Based on our consideration of the arguments and evidence presented at this stage of the proceeding, we determine, for purposes of this Decision, that claims 1, 2, 5–7, and 11 of the ’061 patent are not entitled to receive benefit of the filing date for either the ’861 provisional application or the ’852 provisional application. In particular, we find persuasive Petitioner’s arguments that the provisional applications do not satisfy the written description requirements of 35 U.S.C. § 112 for those claims. Independent claim 1 recites, in part, “a recombinant lentiviral vector which comprises a nucleic acid encoding a functional globin operably linked to a 3.2-kb nucleotide fragment . . . said vector providing expression of the globin in a mammal in vivo.” Ex. 1001, 11:57–67. Independent claim 11 recites, in part, “a recombinant lentiviral vector comprising a nucleic acid encoding a functional globin operably linked to a 3.2-kb nucleotide fragment . . . said vector providing expression of the globin in a mammal in vivo.” Ex. 1001, 12:64–13:7. Based upon our review, we agree with Petitioner that these limitations are not adequately described in the provisional applications. The ’061 patent Specification (and the ’221 Application) describe the term “functional globin gene” as: that does not produce a hemoglobinopathy phenotype, and which is effective to provide therapeutic benefits to an individual with a defective globin gene. The functional globin gene may encode a wild-type globin appropriate for a mammalian individual to be treated, or it may be a mutant form of globin, preferably one which provides for superior properties, for example superior oxygen transport properties. . . . Suitably, the globin may encode α-globin, β-globin, or γ-globin. Ex. 1001, 2:44–55 (emphasis added); see also Ex. 1032, 3:24–4:3 (same). Based on this description, we agree with Petitioner that the ’061 patent claims cover a recombinant vector comprising a nucleic acid encoding a “functional globin” genus that includes wild-type globin and mutant forms of globin, wherein the globin may encode different globin types, i.e., α-, β-, or γ-globin. Patent Owner does not identify, nor do we see, any portion of the provisional applications describing the genus of functional globin. Rather, as Petitioner demonstrates, the provisional applications describe one species of that genus, i.e., the wild-type human β-globin. Pet. 14–18. The provisionals do not describe the “functional globin” genus. Indeed, as Petitioner correctly asserts, during the ’061 patent prosecution, Applicants/Patent Owner, relied on a description of “functional globin,” quoted above, that does not appear and has not counterpart in the provisional applications. Compare Ex. 1001, 2:44–55 and Ex. 1032, 3:24–4:3 with Ex. 1034 and Ex. 1035.” slip op. at 21

“Petitioner asserts that a person of ordinary skill in the art (“POSA”) “at the time of the alleged invention would have had: (1) at least an advanced degree (e.g., a Master’s or Ph.D.) in biochemistry, biotechnology, protein chemistry, genetics, molecular and structural biology, bioengineering, or similar disciplines.” Pet. 17 (citing Ex. 1002 ¶¶ 14–15). Petitioner further asserts that a POSA would have had “(2) several years of post-graduate training or related experience in one or more of these areas” and “(3) an understanding of vector design and the effect of LCR fragments on gene expression, including experience with how the LCR regulates gene expression.” Id.

RulingsFinal written decision- Obviousness (§103) › Analogous artAnalogous artDecided for petitioner
“Patent Owner disagrees for three reasons. First, Patent Owner implies that Burke is not analogous art because Burke does not disclose a door. See PO Resp. 6. Art is analogous when it is: (1) from the same field of endeavor as the claimed invention; or (2) reasonably pertinent to the particular problem faced by the inventor, if the art is not from the same field of endeavor. See In re Bigio, 381 F.3d 1320, 1325–26 (Fed. Cir. 2004). In this case, as observed by Petitioner’s Declarant, Burke expressly describes an application “as in cases where an electrical braking action is required.” Ex. 1004 ¶ 25 (quoting Ex. 1003, 1:18–22). Thus, even under Patent Owner’s argument that Burke is not specific to the field of doors, we agree with Petitioner’s Declarant that Burke is relevant to the problem of braking in electrified devices. Burke discloses an approach to that problem by absorbing energy from a motor, operated as a generator, for the purpose of braking. Ex. 1003, 1:16–25, 3:11–12.” slip op. at 13

“brake shoes based on the application of centrifugal force. Ex. 1009, 5:59– 63. Petitioner’s assertion is that a person of ordinary skill would have found it obvious to use a different braking mechanism as a substitute for a governor to achieve the same function. In particular, Petitioner proposes substitution of the frictional braking mechanism of Shea (i.e., a braking mechanism that is purely mechanical), with the dissipative braking mechanism of Burke (i.e., a braking mechanism that also converts mechanical energy to electrical energy). In this case, the fire door of Shea, with the motor/generator of Burke substituted for the motor/governor of Shea, would operate to blunt or slow the movement of the door on descent while allowing the door to close. See Ex. 1004 (Haas Decl.) ¶ 26. We determine that the asserted combination of Shea and Burke would operate in the same manner as the fire door of Shea—to slow the movement of the door, while allowing the door to close under the force of gravity. Id. ¶ 24. We agree with Petitioner’s Declarant that this would have been an obvious substitution as the use of a known technique to improve functionality. See id. ¶ 26. Petitioner’s proposed combination is thus the substitution of an electrical component for an analog component, which does not destroy the principle of operation because it does not destroy the overall principle of operation of the device. See Mouttet, 686 F.3d at 1332. We conclude that this type of fitting together of teachings would have been obvious to a person of ordinary skill in the art. KSR, 550 U.S. at 420 (“a person of ordinary skill will be able to fit the teachings of multiple patents together like pieces of a puzzle”). Viewing the evidence as a whole, we conclude that a person of ordinary skill in the art would have applied the teachings of Burke regarding regenerative braking to the fire door of Shea in order to improve operation of the door and to make use of excess energy from rotation. We are further persuaded by Petitioner’s arguments that Burke teaches that the braking can have the additional advantage of powering another device and that a person of ordinary skill would have sought a substitution of components in order to achieve the advantages of Burke’s motor/generator. See Pet. Reply 11–12 (quoting Randall Mfg., 733 F.3d at 1363 (“doing so would allow the designer to achieve the other advantages of the Aquino assembly while using a stowage strategy that was very familiar in the industry”)).” slip op. at 15

“However, the additional limitations would not avoid unpatentability because Burke and O’Brien both use a motor/generator system, O’Brien’s motor/generator uses DC power (Ex. 1008, 5:15), Burke and O’Brien both use regenerative braking, and Burke recites the charging of a storage battery by the motor/generator which is capable of braking (Ex. 1003, 3:4–16). Therefore, the asserted combination of Shea, Burke, and O’Brien already contains the features recited as additional limitations in proposed substitute claim 40 (and the similar recitations in proposed substitute claims 41 and 42). We have already concluded supra, that the combination of Shea, Burke, and O’Brien would have been obvious to a person of ordinary skill in the art. Patent Owner does not explain why the additional recitations of its proposed substitute claims would have been nonobvious over this combination. Mot. Amend 4–14. Patent Owner argues that the combination of Shea and Burke would not make use of a DC battery by itself to open or close a door. Id. at 11–12. However, nothing in the additional limitations of proposed substitute claims 40–42 requires that a DC battery provide power to open or close a door without an additional power supply (as discussed above with respect to claim 16). More importantly, the combination of Shea, Burke, and O’Brien would make use of the DC-powered components—the DC motor/generator of O’Brien. Ex. 1008, 5:4–15. Burke discloses using the motor/generator to charge a battery with the regenerated energy. Ex. 1003, 3:12–13. Therefore, the combination of Shea, Burke, and O’Brien already contains the elements of the additional limitations. We conclude that Patent Owner has not met its burden of proving that the additional recitations of proposed substitute claims 40–42 would have been nonobvious over this combination. See Paper 15, 4–16.9” slip op. at 23
- Disclosure Requirements (§112) › Definiteness (Nautilus)DefiniteDecided for patent owner
“As to Petitioner’s argument that proposed substitute claim 43 is indefinite, we determine that the term “substantially uniform speed” is reasonably clear to a person of ordinary skill when read in context of the entire claim limitation and disclosure, which requires the application of “more and more braking” to compensate for the dynamics of the door during closing, e.g., to offset the potential for acceleration due to gravity.
