“overlap to a significant degree, i.e., a person with a Ph.D. in a discipline related to biological sciences and having had at least two years of work experience. However, the parties’ proposals differ slightly in the specific subjects in which a POSA would have had a doctoral degree, and whether the person’s work experience must have been directly related to horseshoe crab Factor C. As an initial matter, we find that a rigid requirement as to the subject of a POSA’s doctoral degree (e.g., biochemical engineering, enzymology), or experience working specifically with horseshoe crab proteins, is not consistent with the evidence of record. See, e.g., Ex. 1067, 20:23–21:2 (Dr. Schaefer testifying that the fact the “name of [his] Ph.D. is immunology . . . does not change the fact that the core of [his] thesis training was really in molecular biology”), 22:3–15 (explaining “the fact that the production of proteins recombinantly is mostly species agnostic”); Ex. 1069, 45:20–47:17 (Dr. Morris testifying that whether a person is a POSA depends on the person’s “experience, [ ] publications,” and work done for the Ph.D. rather than the name of the Ph.D. program). We also find that evidence of record supports Petitioner’s assertion that, for purposes of defining a POSA, “[m]ore education could substitute for experience, and vice versa.” See, e.g., Pet. 19; Ex. 1065, 99:14–100:3. with respect to the claims of the ’318 patent would have had a Ph.D. in molecular biology, biochemistry, or a related discipline, and about two years of experience with cloning genes, expressing cloned genes as proteins, and/or characterizing such cloned genes and proteins, with more education being able to substitute for experience, and vice versa. A POSA may also have collaborated with others, including those with specific experience in utilizing or assessing horseshoe crab Factor C for endotoxin detection and quantitation.” slip op. at 13

“Carrying Out the Invention section, that “[t]he Factor C of the present invention is a Factor C derived from a horseshoe crab,” and states later in the same section that “[e]xamples of the horseshoe crab include . . . Limulus polyphemus.” Ex. 1006, 40. However, none of the remaining portions of ’767 application cited by Patent Owner relate directly to L. polyphemus; instead, the remaining portions of ’767 application cited by Patent Owner are directed to other species, in particular the Japanese horseshoe crab T. tridentatus. Further, Patent Owner’s witness, Dr. Schaefer, conceded that the ’767 application does not contain Factor C sequence information for L. polyphemus. See, e.g., Ex. 1067, 44:25–45:23. Although “[n]o length requirement exists for a disclosure to adequately describe an invention,” Falko-Gunter, 448 F.3d at 1365–1366, we are persuaded that a POSA would not, based on the totality of the above disclosures, reasonably understand that the inventors were in possession of the claimed HEK-293 recombinant L. polyphemus Factor C protein, in view of the state of the art as of December 10, 2013. In this regard, we note that adequate written description of a biological molecule, such as a HEK293 recombinant L. polyphemus Factor C protein, requires “more than a mere statement that it is part of the invention and reference to a potential method for isolating it”; instead, what is required is “‘a precise definition, such as by structure, formula, chemical name, or physical properties,’ not a mere wish or plan for obtaining the claimed chemical invention.” The Regents of the” slip op. at 21

“Pfizer, Inc. v. Apotex, Inc., 480 F.3d 1348, 1364 (Fed. Cir. 2007). Neither do we see Petitioner’s arguments regarding the December 10, 2013 priority date to be “mutually opposed” as Dr. Schaefer testified. Ex. 1067, 216:4– 24. Instead, we credit evidence of record, including Dr. Jain’s testimony and the February 22, 2018 Mizumura Declaration, that existence of the full sequence would permit a more complete analysis and that such an analysis would provide a POSA with a reasonable expectation that the claimed L. polyphemus recombinant protein would have a residual activity within the claimed range. See, e.g., Ex. 1029, 2–5; Ex. 1010, 48; Ex. 1065, 117:14– 130:24 (explaining that comparison of partial sequences in the Tokunaga 1991 publication showed “difference around the cleavage site” between T. tridentatus and L. polyphemus but comparison of the full sequence revealed that “the catalytic triad of histidine, serine, aspartate . . . to be more similar between Tachypleus and Limulus”). Patent Owner asserts that “Petitioner’s reliance on a statement made by Dr. Mizumura in a declaration submitted during prosecution of the ’767 Application fails to fill the gap in the analysis” regarding reasonable expectation of success, because the declaration “offers no evidence of the percentage of conserved amino acid substitutions that exist to support the conclusion that a POSA would have expected residual activity to be maintained between Tachypleus tridentatus and Limulus polyphemus” PO Resp. 47. However, as noted above, Dr. Mizumura provides an alignment of Factor C proteins from the two different species of horseshoe crab, determines that the similarity between the amino acid sequence is 99.5%, states that the amino acid residues that can undergo N-type sugar chain that L. polyphemus, like T. tridentatus, would also be less susceptible to inhibition by ions. Ex. 1029, 4–5. For the reasons discussed above, we also disagree with Patent Owner’s assertion that Petitioner’s reasonable expectation of success argument is “nothing more than conclusory assertions with no support.” PO Resp. 46. Rather, we find Petitioner has shown, by a preponderance of the evidence, that a POSA would have had reason to combine the teachings of Mizumura and the ’498 PCT, with a reasonable expectation of success in arriving at the Factor C protein recited in claim 21.” slip op. at 38

“After consideration of the full trial record, we maintain our construction. From our perspective, the claims themselves support this construction as the claims expand upon the term “electrostatically inhibiting” with specific means for achieving such inhibition. Specifically, claims 1 and 2 recite electrostatically attracting the particulate matter, holding the matter in place, and inactivating the matter. Additionally, the Specification supports our construction as it describes the use of “an electrostatic field such that oppositely charged airborne particulates (including microorganisms) in the vicinity of the surface are electrostatically trapped, held thereto and one or more of the microorganisms so captured is neutralized, killed, inactivated, and rendered harmless.” Ex. 1001, 3:36–40; PO Resp. 10 n.6.” slip op. at 9

This is done by varying the concentration of ingredients . . .[,] thereby adjusting the adhesion and cohesion of the thin film.” Pet. Reply 3 (quoting Ex. 1010, 17). Furthermore, as stated in our Institution Decision, along with that term, the claim language explains that the thin film is meant to stick to the skin or tissue and to hold the particulate matter in place. Inst. Dec. 9–10. The claim language also explains that the cohesion of the formulation is adjusted to provide adequate impermeability to the thin film. Thus, it is reasonable to consider the recited impermeability is a function of the cohesive properties of the thin film, and that such impermeability refers to a property of the thin film, i.e., inhibiting the penetration or passage of matter through it onto the skin or tissue at the application site.” slip op. at 10

On the contrary, far from being a “well-known, well-characterized, and discrete class” the prior art teaches a heterogeneous assembly of different classes of small molecule CRF1 receptor antagonists (Type I, Type II, and “atypical”) displaying a very considerable variety of structures, both in terms of the core pharmacophore (e.g., monocyclic, bicyclic, tricyclic, phenolic, cyclohexyl amide, etc.) as well as in the various side groups.

Patent Owner does not expressly dispute Petitioner’s construction, other than to argue that, by 2011, a person of ordinary skill in the art would have understood “initial” and “secondary” doses to correspond to loading doses and “tertiary” doses to correspond to maintenance doses.

“Here, the claims are directed to methods of administering, i.e., using, a VEGF antagonist for an intended purpose of “treating an angiogenic eye disorder in a patient.” The Specification repeatedly characterizes the method as one for treating angiogenic eye disorders in patients. Apart from the preamble, the independent claims do not elsewhere recite or indicate any other use for the method steps comprising the administration of a VEGF antagonist. Thus, we determine that the preamble sets forth the essence of the invention—treating an angiogenic eye disorder in a patient. Additionally, we find that the preamble provides antecedent basis for claim terms “the patient” recited in the body of each independent claim, and “angiogenic eye disorders” recited in dependent claims 6, 7, 18, and 20. Indeed, without the preamble, it would be unclear to whom the doses of VEGF are administered. Thus, …in view of the evidence of record, namely, the claim language and the written description of the ’338 patent, we find that the preambles of method claims 1 and 14 are limiting insofar as they require “treating an angiogenic eye disorder in a patient.” Id. at 17–18 (citations omitted). We adopt this same reasoning here and find that the preamble of claim 1 reciting “[a] method for treating an angiogenic eye disorder in a patient” is limiting.” slip op. at 34

“We adopt Petitioner’s proposed construction of the claim terms “initial dose,” “secondary dose,” and “tertiary dose.” Petitioner proposes adoption of the definitions expressly set forth in the Specification of the ’681 patent, viz., that the initial dose is the dose “administered at the beginning of the treatment regimen,” and is followed by the secondary doses that are “administered after the initial dose,” and the tertiary doses are “administered after the secondary doses” and may be distinguished from the secondary doses “in terms of frequency of administration.” Ex. 1001, col. 3, ll. 36–44.” slip op. at 37

“If a claim limitation is directed to printed matter, the next step in the Praxair analysis is to determine whether the printed matter is functionally related to its “substrate.” Praxair, 890 F.3d at 1032. Printed matter that is functionally related to its substrate is given patentable weight. Id. (citing DiStefano, 808 F.3d at 850). However, “[w]here the printed matter is not functionally related to the substrate, the printed matter will not distinguish the invention from the prior art in terms of patentability.” Id. (quoting In re Ngai, 367 F.3d 1336, 1339 (Fed. Cir. 2004)). More specifically, printed matter is functionally related to its substrate when the language changes not mere thoughts or outcomes, but provides action steps that the method requires. See C R Bard Inc. v. AngioDynamics, Inc., 979 F.3d 1372, 1381 (Fed. Cir. 2020) (holding that the test for printed matter is whether it “merely informs people of the claimed information, or whether it instead interacts with the other elements of the claim to … cause a specific action in a claimed process.”); see also Bristol-Myers Squibb Co. v. Ben Venue Laboratories, Inc., 246 F.3d 1368, 1376 (Fed.

“A Person of Ordinary Skill in the Art Petitioner contends that a person of ordinary skill in the art would have: (1) knowledge regarding the diagnosis and treatment of angiogenic eye disorders, including the administration of therapies to treat said disorders; and (2) the ability to understand results and findings presented or published by others in the field. Pet. 28. Petitioner asserts that such a person would typically have an advanced degree, such as an M.D. or Ph.D. (or equivalent, or less education but considerable professional experience in the medical, biotechnological, or pharmaceutical field), with practical academic or medical experience in (i) developing treatments for angiogenic eye disorders, including through the use of VEGF antagonists, or (ii) treating of same, including through the use of VEGF antagonists.

“According to the Specification, “the present invention . . . relates to a multimeric chromatography ligand (also denoted a ‘multimer’) comprised of at least two Domain C units, or a functional fragments or variants thereof.” Ex. 1001, 7:27–30. The Specification additionally recites that a multimer containing only domain C units can, however, include linkers. Id. 7:39–41. In addition, the Specification describes that “the multimer comprises one or more additional units, which are different from Domain C.” Id. 7: 44–45. Based on these disclosures in the Specification, a multimer is composed of at least two or more monomers.

“knowledge that any one of the five SPA IgG binding domains are known to bind IgG and can function as a ligand for the purification of antibodies. Linhult and Abrahmsén both expressly suggest that the glycine codon at position 29 can be mutated for an alanine codon in any one of the SPA IgG binding domains E, D, A, B, or C. Ex. 1004, 2; Ex. 1005, 2:32–37. Here, the SPA IgG binding domains comprise a short list of 5 members: E, D, A, B, or C. Of these 5 members, the glycine at position 29 in domain B has already been mutated to an alanine to create a domain Z which has been shown to retain IgG binding activity. Ex. 1004, 6 (Fig. 3). Figure 1A of Linhult is reproduced below. Linhult’s Figure 1A, reproduced above, shows the amino acid alignments of the Z, Z(F30A) and the five homologous domains (E, D, A, B, and C). The three boxes show the α-helices. Ex. 1004, 2; Ex. 1005, Fig. 2. Here, Linhult and Abrahmsén show that the IgG binding domains of SPA – E, D, A, B, and C share many structural similarities. See Ex. 1004, 2 (Fig. 1(a) (reproduced above)); Ex. 1005, 3:25–35. As discussed in our Institution Decision (Dec. 30–31), there are a finite number—five (5)—SPA IgG binding domains and each possesses the dipeptide sequence Asp-Gly known to a be a target for alkaline protein degradation. Therefore, the solution of mutating the glycine at position 29 for an alanine to remove the alkaline sensitive sequence is not a product of innovation, but of ordinary skill and common sense. See Wm. Wrigley Jr. Co. v. Cadbury Adams USA LLC, 683 F.3d 1356, 1364-65 (Fed. Cir. 2012) (quoting KSR, 550 U.S. at 421). It is well established that” slip op. at 37

“Here, the teachings of Linhult, Abrahmsén, and Hober suggest mutating the glycine at position 29 for an alanine in any one of the IgG binding domains of E, D, A, B, or C of SPA in order to avoid protein degradation. Ex. 1004, 2; Ex. 1005, 5:4–9. We, therefore, agree with Petitioner that the art expressly suggests that the glycine codon can be mutated for an alanine codon in any one of the SPA IgG binding domains E, D, A, B, or C. Pet. 23 (citing Ex. 1002 ¶¶ 99–111). Attaching any one of SPA mutated IgG binding domains E D A B or C to a matrix using “known ligand-construction methods to yield a predictable result[] (e.g., the claimed affinity chromatography matrix)” would have been obvious. Pet. 25 (citing Ex. 1002 ¶ 130). As the Federal Circuit has explained, “[w]here a skilled artisan merely pursues ‘known options’ from ‘a finite number of identified, predictable solutions,’ the resulting invention is obvious under Section 103.” In re Cyclobenzaprine Hydrochloride Extended-Release Capsule Patent Litig., 676 F.3d 1063, 1070 (Fed. Cir. 2012) (quoting KSR, 550 U.S. at 421). Accordingly, we agree with Petitioner that the combination of Linhult Abrahmsén, and Hober expressly suggests mutating the glycine codon for an alanine codon in any one of the SPA IgG binding domains E, D, A, B, or C. Pet. 23 (citing Ex. 1002 ¶¶ 99–111). We also agree that the cited art teaches using these mutant SPA domains in column chromatography for the isolation of antibodies.” slip op. at 36

As a Senior Litigation Support Specialist, working in consultation with a Regeneron custodian of records, and with access to the restricted Regeneron server where the 16 Exhibits at issue are kept, Ms. Weber qualifies as a person with knowledge, under Rule 901(b)(1), that the Exhibits were true and correct copies of the records in Regeneron’s possession.
