Claims 1–19 are unpatentable as obvious over the Lesniak- and Native-based grounds; the Squatch and Sturgis ground fails because Squatch was not shown to be a printed publication.
RulingsFinal written decision- BurdenDecided for patent owner
“We agree with Patent Owner that Petitioner has not shown sufficiently that Squatch is a printed publication. As described above, Petitioner relies on Squatch as a “website excerpt” placed on its site at the relevant time, but has not produced a screen shot of the website to show that it ever existed. See Ex. 1059. Petitioner provides internal documents that purport to describe what would have been on Dr. Squatch’s website at the relevant time, but falls short of establishing what was on the website for the interested consumer to view. Thus, we determine that this ground fails.” slip op. at 55

“However, we prefer Patent Owner’s definition of the required 2–3 years of experience in “the development and syntheses of nucleosides, nucleotides, and nucleic acids, including, but not limited to, the syntheses of oligonucleotides through solid phase oligonucleotide synthesis (‘SPOS’)” to Petitioner’s more generalized requirement of having experience in “medicinal chemistry, synthetic organic chemistry, and nucleic acid chemistry, including the development of oligonucleotide therapeutics, diagnostics, or building blocks.” Both parties acknowledge that the level of skill in the art is very high. See, e.g., Resp. 17; Reply 2. We find that, to achieve a level of ordinary skill in the art, a person with the requisite educational background would require 2–3 years of experience for one possessing a doctorate in the relevant field, or 3–5 years for one with a lesser degree (to compensate for the additional educational experience gained by achieving a doctorate) in the specific techniques recited by Patent Owner. We reject the terminal clause “pursuant to P(III) chemistry” proposed by Patent Owner as redundant in that a person engaged for a number of years in “the development and syntheses of nucleosides, nucleotides, and nucleic acids” including SPOS, would likely have an operant knowledge of P(III) chemistry. Consequently we adopt the following definition of a person of ordinary skill in the art: “A person of ordinary skill in the art having a Ph.D. (or equivalent degree) in organic or medicinal chemistry, and 2 to 3 years of post-graduate work experience in the development and syntheses of nucleosides, nucleotides, and nucleic acids, including, but not limited to, the syntheses of oligonucleotides through solid phase oligonucleotide synthesis (‘SPOS’)” and, alternatively, “a person of ordinary skill in the art would have a Bachelor’s or Master’s degree in organic or medicinal chemistry who had at least 5 years of extensive work experience in these fields.”” slip op. at 12

Patent Owner’s argument that Dr. Baran is principally experienced in P(V) techniques presupposes that experience in that technique indicates an ignorance of P(III) methodologies. We do not find this position consistent with the breadth of Dr. Baran’s C.V.

“We adopt the same reasoning here, and conclude that the evidence of record and the Specification of the ’681 patent support construing the preamble’s recitation of a “method for treating a patient with an angiogenic eye disorder” as meaning administering a compound, i.e., the recited VEGF antagonist, to a patient for the purpose of improving or providing a beneficial effect in their angiogenic eye disorder. We find that, as in Eli Lilly & Co. v. Teva Pharms. Int’l GmbH, although the claims “encompass a clinical result, they do not require such a result.” (emphasis added). 8 F.4th 1331, 1343 (Fed.

“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. 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. PO Resp. 13 (citing Ex. 2056 ¶ 66; Ex. 2349, 6–11. Patent Owner contends that the purpose (and expected effect) of loading doses was to achieve visual acuity gains and retina drying, and the goal of less frequent maintenance doses was to maintain the efficacy achieved with loading doses. Id. at 14 (citing Ex. 2056 ¶ 66). As we have explained above, we do not find persuasive Patent Owner’s argument that the definition of these terms requires a high, or otherwise defined, degree of efficacy. As we stated in the -00881 and -01225 Decisions: Based on those express definitions in the Specification, we do not find cause to construe the terms differently. In particular, we do not find that the Specification requires the “tertiary doses” to maintain any efficacy gain achieved after the initial and secondary doses, or that the term suggests any specific level of efficacy. The Specification unequivocally states that “[t]he terms ‘initial dose,’ ‘secondary doses,’ and ‘tertiary doses,’ refer to the temporal sequence of administration of the VEGF antagonist.”” slip op. at 18

“If a claim limitation is directed to printed matter, the second step of 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).

“Decision. See Ex. 3001, 12–23. As an initial matter, we are not persuaded by Patent Owner’s reliance on Sanofi and Eli Lilly. See PO Resp. 9. In Sanofi, a non-precedential decision, the Federal Circuit held that the preamble to the claims at issue, reciting “[a] method of increasing survival comprising administering to a patient in need thereof” was limiting upon the claims, in conformance with the court’s prior decisions in Jansen v. Rexall Sundown, Inc., 342 F.3d 1329, 1333 (Fed. Cir. 2003) and Rapoport v. Dement, 254 F.3d 1053 (Fed. Cir. 2001). Sanofi, 757 F. App’x at 992–93. Furthermore, the court held that, because the preamble was limiting, and recited a “method of increasing survival” the proposed claims would now clearly require “increasing survival.” Id. at 994. The preamble to claim 1 of the ’681 patent, however, recites no such “increase” with respect to efficacy, but merely recites “A method for treating an angiogenic eye disorder in a patient,” and the remainder of the claim requires no specific efficacy requirement. Nor does Eli Lilly support Patent Owner’s position. In Eli Lilly, the court upheld the Board’s conclusion that the preamble reciting “a method for treating headache in an individual” was limiting upon the claims. Eli Lilly, 8 F.4th at 1343. However, it noted, in upholding the Board’s conclusion, the Board also “found that while the claims encompass a clinical result, they do not require such a result.” Id. (emphasis added). We also find that the similar language of the preamble to challenged claim 1 of the ’681 patent, although encompassing clinical efficacy, does not require it, let alone a “high degree of efficacy.”” slip op. at 33

“the preamble’s recitation of a “method for treating” requires a high level of efficacy. In the -00881 Decision, the Board rejected Patent Owner’s similar argument because it required improperly importing limitations into the claims. See Ex. 3001, 22. Specifically, the Board found that: [W]hen the Specification explains that “[t]he amount of VEGF antagonist administered to the patient in each dose is, in most cases, a therapeutically effective amount,” and discloses that “a therapeutically effective amount can be from about 0.05 mg to about 5 mg,” we find that a POSA would have understood that any dosage amount within that range administered according to the invention may, in some cases, result in a detectable improvement in “one or more symptoms or indicia of an angiogenic eye disorder,” or be one that “inhibits, prevents, lessens or delays the progression of an angiogenic eye disorder,” or it may not. In either event, the VEGF antagonist would have been administered for the purpose of treating the eye disorder. In other words, the method of treating the patient with the eye disorder is performed upon administration of the VEGF antagonist to the patient for the purpose of achieving an improvement or beneficial effect in the eye disorder, regardless whether the dosage amount administered actually achieves that intended result. Id. at 21–22 (citation omitted). Furthermore, the Board found that: Patent Owner proposes that the claims require not only achieving a therapeutically effective result, but more specifically, achieving a “high level of efficacy that was noninferior to the standard of care by the time the patent was filed in 2011.” In the Sur-reply, Patent Owner describes a “highly effective treatment for angiogenic eye disorders” as “one that is on par to Lucentis or off-label Avastin and can produce visual acuity gains, not just slow vision losses.” The Specification refers to “a high level of efficacy” in one instance, i.e., in the “Background” section. The Specification does not describe there, or elsewhere that “treating,” in the context of the claims or in the art, requires achieving a “high level of efficacy” or providing results “on par to Lucentis or off-label Avastin.” Id. at 22 (citations omitted). We adopt the same reasoning here, and find that, for the purposes of this Decision, the evidence of record and the Specification support construing the preamble’s recitation of a “method for treating a patient with an angiogenic eye disorder” as meaning administering a compound, i.e., the recited VEGF antagonist, to such patient for the purpose of improving or providing a beneficial effect in their angiogenic eye disorder.

“The terms “initial dose,” “secondary doses,” and “tertiary doses,” refer to the temporal sequence of administration of the VEGF antagonist Thus, the “initial dose” is the dose which is administered at the beginning of the treatment regimen (also referred to as the “baseline dose”) ; the “secondary doses” are the doses which are administered after the initial dose; and the “tertiary doses” are the doses which are administered after the secondary doses. The initial, secondary, and tertiary doses may all contain the same amount of dosing regimens, but will generally differ from one another in terms of frequency of administration.

“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

“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.

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.

“We are not persuaded that a person of ordinary skill in the art could be thought of as a “team of individuals.” We find no support in Sankyo for Patent Owner’s contention that “a person of ordinary skill in the art can have the knowledge and experience of multiple individuals working across different arts.” See PO Resp. 8. Rather, in Sankyo, the Federal Circuit looked to the qualifications of the inventors of the patent at issue, all of whom were specialists in drug and ear treatments and noted that others working in the same field as the inventors were of the same skill level. Sankyo, 501 F.3d at 1257. Finding that such specialty training was a 9 requisite for ordinary skill in the art, the court defined the level of ordinary skill in the art in that case as “a person engaged in developing pharmaceutical formulations and treatment methods for the ear or a specialist in ear treatments such as an otologist, otolaryngologist, or otorhinolaryngologist who also has training in pharmaceutical formulations.” Id. We conclude that there is, as Petitioner acknowledges, little substantial difference between the qualifications of the “team” proposed by the parties, and those of the individual skilled artisan defined in our Decision to Institute. Such an individual would have had not only several years of experience researching treatments for autoimmune disorders, including rheumatoid arthritis, but would additionally have access to individuals skilled in clinical medicine, pharmacokinetics and formulation. Indeed, Petitioner’s expert, Dr. Shah, acknowledges that an individual person of skill in the art “would have had access to individuals skilled in clinical medicine, pharmacokinetics and formulation.” Ex. 1032 ¶ 27. This is consistent with our prior definition. We consequently adopt, for this Final Written Decision, the definition of a person of ordinary skill in the art as defined in our Decision to Institute and quoted above because it appears consistent with the problems addressed in the ’677 Patent and the prior art of record. See Dec. 6. Furthermore, the prior art itself can reflect the appropriate level of ordinary skill in the art. Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). Regardless of the level of skill adopted, our analysis and findings would remain the same.” slip op. at 9

“Fixed dose” Petitioner asserts that the claim term “fixed dose” is defined in the Specification as “a dosage of a drug, such as an anti-IL-6R antibody which is administered without regard to the patient’s weight or body surface area (BSE), i.e., it is not administered as either a mg/kg or mg/m2 dose.” Pet. 27 (quoting Ex. 1001, col. 15, ll. 15–18). Patent Owner does not dispute this definition. PO Resp. 9 n.9. Because the term “fixed dose” is defined by the 11 Specification and is not disputed by the parties, we determine, based on the current record, that this term requires no further construction. slip op. at 11

“natural reading of this claim language shows a functional limitation that simply requires that the claimed subcutaneous administration device be capable of containing and delivering to a patient a fixed dose of the drug. As such, we conclude that this functional language is limiting upon the claim. See, e.g., K-2 Corp. v. Salomon S.A., 191 F.3d 1356, 1363 (1999) (holding that functional language is limiting upon an apparatus claim). We decline to adopt, however, Patent Owner’s construction of a patient as being a person “with an IL-6-mediated disorder” or requiring the claimed device to “safely and effectively deliver that amount of drug subcutaneously to a patient” and to accommodate the risk of serious immunogenic reactions due to aggregation and viscosity[,] … as well as the obstacles of aggregation instability, injection difficulties, and patient discomfort.” See PO Resp. 12. To adopt these definitions is to impermissibly extend the scope of the claims through claim construction beyond the language of the claims, which do not recite this language. To require that the patient be in need of treatment for an IL-6 mediated disease, as suggested by Patent Owner, is to place an additional limitation on the device that is not functional, but rather relates to the nature of the individual receiving the subcutaneous administration. To the contrary, we interpret this functional language as requiring the claimed device to be capable of delivering the contained dosage to any “patient” whether or not they have a specific medical condition or without respect to ancillary conditions or concerns that may apply. If the device is capable of delivering the dosage subcutaneously to any patient, that is 15 sufficient for this functional limitation, and we decline to import additional limitations into the claim, as Patent Owner urges us to do. We therefore construe the claim phrase “delivers to a patient” as a functional limitation of the claims that requires that the claimed device be capable of subcutaneously delivering the dose contained within it to a person.” slip op. at 15

“device, which contains and delivers to a patient a 162 mg fixed dose” of tocilizumab within the four corners of NCT ’653, we next inquire whether NCT ’653 inherently discloses the claimed device. A reference may anticipate inherently if a claim limitation that is not expressly disclosed “is necessarily present, or inherent, in the single anticipating reference.” Verizon Servs. Corp. v. Cox Fibernet Va., Inc., 602 F.3d 1325, 1337 (Fed. Cir. 2010); see also Agilent Techs., Inc. v. Affymetrix, Inc., 567 F.3d 1366, 1383 (Fed. Cir. 2009) (holding that the “very essence of inherency is that one of ordinary skill in the art would recognize that a reference unavoidably teaches the property in question”). There can be little logical doubt that NCT ’653 necessarily teaches “a subcutaneous administration device” for the simple reason that the reference teaches that randomized subjects receive “tocilizumab 162 mg [subcutaneously]” and a person of ordinary skill in the art would have understood that a suitable device is required to do this. But the claims also 27 require that the subcutaneous administration device also “contains and delivers to a patient a 162 mg fixed dose of tocilizumab.” Petitioner contends that a person of ordinary skill in the art would have understood that the “subcutaneous administration device” used in the study contained and delivered a 162 mg fixed dose of tocilizumab to the patient. Pet. 31. We are not persuaded, however, that an ordinarily skilled artisan would understand that NCT ’653 necessarily discloses that the subcutaneous administration device was one capable of containing and delivering 162 mg of tocilizumab. Certainly, it would be logical for a person of ordinary skill in the art to assume that a device used to administer the dose was capable of delivering the whole dose in a single administered injection. But the reference does not rule out the possibility that another method could be used, e.g., two injections, each from a device capable of containing and delivering a dose only of 81 mg. Such an administration, though perhaps unlikely, is not categorically excluded by the disclosures of NCT ’653. As such, we conclude that NCT ’653 does not inherently disclose “a subcutaneous administration device, which contains and delivers to a patient a 162 mg fixed dose” of tocilizumab because it does not disclose that the subcutaneous administration device[s] necessarily “contains and delivers” the 162 mg fixed dose. Because we find that NCT ’653 neither expressly not inherently discloses all of the limitations of claims 1 and 5, we conclude that the reference does not anticipate independent claims 1 and 5. Consequently, 28 Petitioner has failed to meet its burden of showing, by a preponderance of the evidence, that claims 1 and 5 are unpatentable under 35 U.S.C. § 102.” slip op. at 27

“of individuals” is not conventional. Dec. Inst. 8.

“Here, the Specification reveals that “per dose” does not mean “per injection.” Indeed, the Specification treats those terms differently. For example, in describing “the invention,” the Specification repeatedly follows “per dose” with an exemplary parenthetical or clause specifying the frequency of administration. For example, the Specification states that “the invention concerns a method of treating an IL-6-mediated disorder . . . wherein the anti-IL-6R antibody is administered as a fixed dose of 162 mg per dose (e.g. administered every week or every two weeks).” See Ex. 1001, 4:33–38 (emphasis added); see also id. at 5:4–8 (stating “[t]he invention also concerns a method of treating an IL-6-mediated disorder . . . wherein the anti-IL-6R antibody is administered as a fixed dose of 324 mg per dose or 648 mg per dose (e.g. every four weeks or once every month)”) (emphasis added); 24:54–59 (stating “the invention provides a method of treating an IL-6 mediated disorder . . . wherein the anti-IL-6R antibody is administered as a fixed dose of 162 mg per dose (e.g. every week, every two weeks, or every ten days)”) (emphasis added). Thus, the Specification repeatedly interprets the term “per dose” to describe the frequency of the dose, and not the number of injections to administer the dose. In contrast, when specifying a single injection, the Specification uses the terms “per injection” or a “single dose.” For example, the Specification states, “[a]vailable subcutaneous formulation is in a 1 mL prefilled syringe delivering 0.9 mL 162 mg TCZ per injection.” Id. at 49:55–56 (emphasis dose of 0.9 mL corresponding to a dose of TCZ 162 mg TCZ”) (emphasis added). Thus, although the Specification makes clear when a single injection is used by stating “per injection” or “single dose,” the ’264 Patent does not use either of those terms in the claims.” slip op. at 14

“Whether to treat a preamble as a claim limitation is determined on the facts of each case in light of the claim as a whole and the invention described in Cir. 2003). The Federal Circuit “has not hesitated to hold preambles limiting when they state an intended purpose for methods of using a compound.” Eli Lilly & Co. v. Teva Pharms. Int’l GmbH, 8 F.4th 1331, 1342 (Fed. Cir. 2021). Where, as here, the claims are directed to methods of using a composition for a specific purpose (i.e., treating rheumatoid arthritis), and the method comprises a single step of administering that composition, the Federal Circuit “has generally construed statements of intended purpose in such method claims as limiting.” Id. at 1340. Moreover, as Patent Owner notes, the preamble provides antecedent basis for terms in the body of the claims. That is, the preamble recites “treating rheumatoid arthritis (RA) in a patient” and the claims recite “administering to the patient” (claims 1 and 10), “the RA patient” (claims 3– 5), and “administering to the RA patient one or more additional drug which treats the RA” (claim 6). Thus, considering the claims as a whole and the invention described in the patent, we determine the preamble of the claims to be limiting. See Eli Lilly, 8 F.4th at 1343 (finding preamble limiting where it provides antecedent basis for terms in the body of the claims). slip op. at 17

“benefit.” Ex. 2009 ¶ 54. Patent Owner and Dr. Silverman, however, ignore the other half of the Specification’s definition of “treatment,” which states: “‘Treatment’ of a subject herein refers to both therapeutic treatment and prophylactic or preventative measures.” See Ex. 1001, 15:1–2 (emphasis added). Thus, limiting the definition of “treatment” to mean only “therapeutic treatment,” as Patent Owner asserts, is inconsistent with the express definition in the Specification and, therefore, incorrect on its face. See Phillips, 415 F.3d at 1316 (stating “the specification may reveal a special definition given to a claim term by the patentee that differs from the meaning it would otherwise possess. In such cases, the inventor’s lexicography governs.”). Moreover, the Specification defines the term “effective amount” as “an amount of the antibody that is effective for treating the IL-6 disorder.” Id. at 15:3–4. If “treatment” of the IL-6 disorder required efficacy, it would not be necessary for the Specification to define an “effective amount” for treating the disorder separately, as efficacy would be implicit in the term “treatment.” Consistent with this, the Specification defines certain subjects as “inadequate responder[s]” to various medications because they have experienced “an inadequate response to previous or current treatment . . . because of toxicity or inadequate efficacy.” Id. at 14:46–61 (emphasis added). Thus, the Specification uses the term “treatment” to encompass treating a patient with a certain medication, regardless of safety or efficacy.” slip op. at 19
