“In our Institution Decision, we adopted Petitioner’s definition of a person of ordinary skill in the art (“POSITA”) as it was undisputed at the time and consistent with the evidence of record. Inst. Dec. 7–8. Based on our consideration of the full record, we maintain our determination that a POSITA at the time the application for the ’802 patent was filed “would have had at least an undergraduate degree in pharmacy, chemistry, biochemistry, biomedical engineering or a closely related field, such that the POSITA generally understand[s] pharmaceutical formulation.” Pet. 12. Additionally, we agree with Petitioner that “[a] POSITA would be familiar with the chemical ingredients in the [’802] Patent, biocidic agents, and cationic agents, have knowledge of airborne particles including viruses and bacteria, and understand electrostatic fields, electrostatic attraction and repulsion, adhesion and cohesion.” Id.

After consideration of the full trial record, we maintain our construction of the preamble of claims 1, 2, and 8 as limiting for the reasons set forth in our Institution Decision. Id. Briefly, the preamble of independent claims 1, 2, and 8 limits the challenged claims as both the preamble and the body are used to define the subject matter claimed. See Allen Engineering Corp., v. Bartell Industries, Inc., 299 F.3d 1336, 1346 (Fed. Cir. 2002). In particular, the preamble is “necessary to give life, meaning and vitality” to the claim, see id., because it provides the only description in the claim for the application site of the formulation, i.e., “to skin or tissue of nasal passages,” and how the formulation is applied, i.e., “in a thin film.”” slip op. at 8
- Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Term construed board ownDecided for petitioner
“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
- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for petitioner
“We adopt the parties’ construction of “adequate impermeability” that has been accepted in the related district court litigation: “Adequate impermeability” refers to the “thin film holding harmful particles in place and inhibiting them from penetrating the thin film and contacting the skin or tissue of an individual’s nasal passages. 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

“We deny the motion to exclude the referenced argument in Petitioners’ Reply, as well as the invitation to consider the motion as one to strike the argument. As Patent Owner notes in the motion, Patent Owner raised this issue previously in this proceeding. PO Mot. Exclude 5. At that time, we denied Patent Owner’s request for authorization to file a motion to strike the referenced argument in the Reply. It is improper for Patent Owner to now seek to strike the argument in a motion to exclude. A motion to exclude is not the proper vehicle to address arguments or evidence that a party believes exceeds the proper scope of a reply. See USPTO, Consolidated Trial Practice Guide (2019) at 79, available at: https://www.uspto.gov/sites/default/files/documents/tpgnov.pdf?MURL= (last visited October 27, 2022) (“CTPG”). Moreover, as Petitioners correctly assert, Patent Owner has failed to satisfy the prerequisite for filing a motion to exclude by failing to timely file an objection. See 37 C.F.R. 42.64(b)(1); CTPG 78–79. Patent Owner has not been left without an opportunity to address the Reply argument. When we denied authorization to file a motion to strike, we authorized Patent Owner to file, with its Sur-Reply, a table identifying any portion of the Reply that Patent Owner considers to have exceeded the scope of the Reply. Further, we explained that Patent Owner, alternatively, may address that contention, or the merits of any newly-raised arguments or evidence in its Sur-Reply. Indeed, Patent Owner addressed the issue in its 26 Sur-Reply for our consideration. Thus, Patent Owner had sufficient opportunity to identify in its Sur-Reply its contentions regarding Petitioners’ allegedly inappropriate Reply argument and took advantage of that opportunity. That is sufficient for us to consider the issue and determine whether such argument should be disregarded. See CTPG 80.” slip op. at 26
- Skill levelSkill level petitioner adoptedDecided for petitioner
“We find that Petitioner’s definition is the better definition for purposes of this proceeding. We acknowledge that the claims of the ’069 patent are directed to a “method for treating an angiogenic eye disorder in a patient” 29 and that the actual practice of the method would therefore seem to be limited to those who have the ability to treat patients, i.e., physicians, etc. However, we find Patent Owner’s definition to be unduly limiting. Individuals who are involved in drug development or sub-clinical level testing of drugs for treating eye disorders may be extremely knowledgeable about the development of the treatment of eye disorders and drug development, and able to comprehend and evaluate the teachings of the prior art. See, e.g., Pet. 25. Such individuals might not possess an M.D. degree, but instead possess a Ph.D. in a “biotechnological, or pharmaceutical field,” or a lesser degree with a corresponding increased depth of experience, as suggested by Petitioner. We agree that such individuals should be considered persons of ordinary skill in the art. We also find that Petitioner’s definition is commensurate with the level of skill reflected in the prior art. See, e.g., Exs. 1006, 1010, 1030, 1033; see also Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (explaining that specific findings regarding ordinary skill level are not required “where the prior art itself reflects an appropriate level and a need for testimony is not shown” (quoting Litton Indus. Prods., Inc. v. Solid State Sys. Corp., 755 F.2d 158, 163 (Fed. Cir. 1985))). We consequently adopt Petitioner’s definition of a person of ordinary skill in the art has having an M.D. or Ph.D. or equivalent, or less education but considerable professional experience in the medical, biotechnological, or pharmaceutical field, and having practical academic or medical experience in developing treatments 30 for angiogenic eye disorders or treating angiogenic eye disorders including through the use of VEGF antagonists.” slip op. at 29

“On this record, we find Petitioner’s proposed constructions are supported by intrinsic and extrinsic evidence. See Pet. 18–23. We agree with Petitioner here that “a patient” or “the patient” should have its ordinary and customary meaning of “one or more patients,” as opposed to a “patient population” as Patent Owner has previously argued in a district court litigation involving another party. See id. at 19–20. Indeed, Patent Owner agrees. See Reply 19 (“There is no dispute that ‘a patient,’ as recited in the ’827 claims, refers to ‘one or more patients.’”). We also agree with Petitioner that the dependent claims requiring treating patients with schizophrenia and manic depressive psychosis supports the conclusion that “treating a patient with an antipsychotic” in independent claims 25, 40, and 56 includes treatment of a patient with these particular diseases. See Pet. 20–21. 10 On this record, we further agree with Petitioner that “manic depressive psychosis” would be interpreted by a person or ordinary skill in the art as “bipolar disorder,” which includes Bipolar I Disorder, Bipolar II Disorder, Cyclothymia, and Bipolar Disorder Not Otherwise Specified.

“Based on Saji’s preferred dose range of 5 to 100 mg/day, which overlaps with the “from 20 to 120 mg/day” range required by each challenged independent claim, Petitioner argues that an ordinarily skilled artisan would have been “motivated to conduct dose ranging studies and would find the claimed dosing regimens.” Pet. 62; see also id. at 55 (contending that “dose ranging was a routine part of drug development” (citing Ex. 1030)). Dr. Stahl’s testimony supports Petitioner’s argument. Indeed, Dr. Stahl testifies that, although with some drugs, it can be difficult to find a safe and effective dose, or to get an effective dose into the patient, neither is the case with lurasidone. Ex. 1054, 141:3–14; see also id. at 142:2–6 (“Q.

“We conclude from a review of Fang and Taylor that they are not substantially the same art nor is Petitioner making substantially the same argument as was presented the Office during prosecution of the ’061 Patent based on Fang. We find that the way in which Fang and Taylor work appear to be materially different. Fang appears to apply only suction to the skin whereas Taylor, with the sealingly connected suction cup, appears to apply a cyclical vacuum that Dr. Prisco testifies meets the claim limitations requiring generation of a pattern of negative and positive pressures, modulated with respect to a reference pressure. Ex. 1002 ¶¶ 62–64, 75. Thus Taylor appears to teach the claim element Patent Owner argued during prosecution was missing from Fang. Also, in applying factors (b) and (d) of Becton, Dickinson, because of such differences noted above, we find that Taylor is not cumulative of Fang, which was considered and applied by the Office during prosecution of the ’061 Patent. 4. Conclusion Thus, we find that Taylor and Fang are not substantially the same art, nor were substantially the same arguments based on these references presented in the Petition and during prosecution of the ’061 Patent, respectively. As discussed above, because Petitioner primarily relies on Taylor in all four grounds for teaching the modulation of positive and negative pressures with respect to a reference pressure as required by all of the challenged claims, we also find that, overall, the same or substantially the same art was not previously presented to the Office nor were the same or substantially the same arguments previously presented to the Office. Therefore, we do not need to reach the application of the remaining Becton, Dickenson factors relating to whether the Petitioner has demonstrated a material error by the Office.

Pet. 22 (citing Ex. 1003 ¶ 49). We find that Patent Owner’s definition of the ordinarily skilled artisan, i.e., a person having “a Ph.D. degree, or equivalent education, in polymer chemistry, or a bachelor of science degree in chemistry or a closely related field and several years of experience in the development and manufacture of polymer materials for use as tissue sealants,” PO Resp. 15–16 (citing Ex. 2006 ¶ 27), does not differ materially from Petitioner’s definition. Furthermore, our analysis would be the same under either parties’ definition.” slip op. at 9

- Claim Construction › Intrinsic evidence (Phillips canons) › Preamble limiting or notPreamble limitingDecided for patent owner
“In general, a preamble limits the invention if it recites essential structure or steps, or if it is necessary to give life, meaning, and vitality to the claim.” Catalina Mktg. Int’l, Inc. v. Coolsavings.com, Inc., 289 F.3d 801, 808 (Fed. Cir. 2002) (quotation omitted). “Conversely, a preamble is not limiting where a patentee defines a structurally complete invention in the claim body and uses the preamble only to state a purpose or intended use for the invention.” Id. Here, we determine that the preamble phrase “suitable to coat a tissue of a patient” is not merely a statement of purpose, but instead represents the “essence or a fundamental characteristic of the claimed invention.” Vizio, Inc. v. Int’l Trade Com’n, 605 F.3d 1330, 1340 (Fed. Cir. 2010). In Vizio, the Federal Circuit held that a preamble reciting “for decoding” certain data “is properly construed as a claim limitation” because the apparatus and method claims reciting that preamble “would have little meaning without the intended objective of decoding.” Id. at 1341. Similarly here, we determine that the method step of claim 1—namely, mixing reactive nucleophilic precursor species, electrophilic precursor species, and a visualization agent—would have little meaning without the intended objective of forming a hydrogel coating on the tissue of a patient. Put differently, there would be no reason to perform the method step of claim 1 but for forming a hydrogel coating on the patient’s tissue. See Ex. 1001, 39:56–40:2 (claim 1) (providing that the reactive precursors crosslink after contact with the tissue to form a hydrogel in the form of a coating). Thus, we determine that “suitable to coat a tissue of a patient” is limiting in this case because it gives “life and meaning” to method claim 1. We further find that the arguments and evidence in this case show that skilled artisans would reasonably interpret “suitable to coat a tissue of a patient” as encompassing a biocompatibility requirement. Although Petitioner correctly notes that “[n]one of challenged claims recite the term ‘biocompatible,” Petitioner acknowledges that skilled artisans understand “that hydrogels are, by their nature as water-swelled materials, known to be biocompatible.” Pet. Suppl. Br. 4–5. Petitioner’s expert, Dr. Lowman, declared that “biocompatibility is presumed as a fundamental aspect of the claimed and disclosed inventions.” Ex. 2018 ¶ 40. And in his deposition, Dr. Lowman testified that skilled artisans would understand “biocompatible” to mean that the hydrogel composition is “suitable for use and tolerated by a patient.” Ex. 2019, 13:2–11 (emphasis added). Thus, we agree with Patent Owner that “suitable to coat a tissue of a patient” reasonably encompasses a biocompatibility requirement for the hydrogel composition. slip op. at 12

RulingsFinal written decision- Skill levelSkill level patent owner adoptedDecided for patent owner
“Patent Owner asks that we adopt the definition of the level of ordinary skill in the art utilized by both the Petitioner and Patent Owner in the 172 IPR that includes “the skill sets of both a physician treating RA patients and a pharmacokineticist with experience in monoclonal antibodies.” Resp. 17–18; Coherus, Case IPR2016-00172, slip op. at 5–6. Petitioner notes that “[t]o the extent that the level of ordinary skill would have included the skills of a pharmacokineticist, this Petition provides that perspective through the Declaration of Dr. Jusko (Ex. 1004), a world-renowned expert in this field.” Pet. 17–18. As both parties have applied a definition of the level of ordinary skill that includes a pharmacokineticist, and such a level of ordinary skill in the art is reflected in the sophistication of the technology and the educational level of those working in the field of the invention, we adopt the level of ordinary skill in the art for the ’135 patent set forth in the 172 IPR. See In re GPAC, 57 F.2d 1573, 1579 (Fed. Cir. 1995) (setting forth factors to be considered in determining the level of ordinary skill in the art); Coherus, Case IPR2016-00172, slip op. at 5–6.” slip op. at 6

“the 172 IPR, we discussed the meaning of the term “for a time period sufficient to treat the rheumatoid arthritis” citing extensively to the Specification of the ’135 patent. See Coherus, Case IPR2016-00172, slip op. at 6–9 (Paper 60). We adopt here the discussion and the findings set forth in that inter partes proceeding construing the claim term “for a time period sufficient to treat the rheumatoid arthritis.” The construction of this term, as set forth in the companion proceeding, i.e., “for a time period sufficient to reduce the signs, symptoms, and/or progression of RA,” is consistent with our Decision on Institution, where we stated that the claims do not require a particular level of efficacy and with the description in the Specification of the ’135 patent of administering the antibody for therapeutic purposes to alleviate the symptoms and/or progression of RA. See Ex. 1001, 24:25–60. Nothing in Patent Owner’s discussion set forth above concerning its proffered construction alters our view that the claim term does not require a particular level of efficacy. As we found in the 172 IPR, Patent Owner’s proposed construction introduces ambiguity in the claims. Patent Owner discusses “meaningful reduction” in or reducing “significantly” a patient’s signs, symptoms, and disease progression without providing any specific measure for achieving such a goal. See Resp. 64–65. We agree with the 172 IPR finding that such ambiguity arises because “Patent Owner’s construction does not indicate whether reducing ‘significantly’ the signs and symptoms of RA means that patients self-report better overall health status on a health survey, or that patients must achieve an ACR20 response, or even an ACR70 response, or a combination of all of the reported outcome measures.” Coherus, Case IPR2016-00172, slip op. at 9 (Paper 60). Therefore, consistent with our decision in the 172 IPR and with our Decision on Institution, we determine that the phrase “for a time period sufficient to treat the rheumatoid arthritis” does not require any particular level of efficacy and, under the broadest reasonable construction, means “for a time period sufficient to reduce the signs, symptoms, and/or progression of RA.”” slip op. at 10

“One question before us then, is whether a person of ordinary skill in the art would have had a reason to modify van de Putte 1999’s 20 mg weekly dose to a 40 mg biweekly dose based on the express teaching of Kempeni 1999 of a two-week interval for dosing. As with other factual questions, Petitioner bears the burden of proving that the skilled artisan would have been motivated to modify the dosing regimen of van de Putte 1999 to arrive at the claimed invention. In re Magnum Oil Tools Int’l, 829 F.3d 1364, 1375 (Fed. Cir. 2016) (burden-shifting “does not apply in the adjudicatory context of an IPR”).

“A reference teaches away from the claimed invention if it criticizes, discredits, or would have discouraged a person of ordinary skill in the art from “following the path set out in the reference,” or if a person of ordinary skill “would [have been] led in a direction divergent from the path that was taken by the applicant.” In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994); see In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004). The mere disclosure of alternative designs, however, does not teach away. In re Mouttet, 686 F.3d 1322, 1333–34 (Fed. Cir. 2012). Patent Owner fails to view what the references as a whole teach one of skill in the art. First, van de Putte 1999 teaches subcutaneous administration of fixed doses, 20/40/80 mg doses, of D2E7. Ex. 1008, 7; Ex. 1037, 159:10–160:20. Patent Owner attempts to make efficacy comparisons between these doses as explained above, see Resp. 32–33, but as Dr. Weisman testifies and Dr. Gibofsky and Patent Owner agree, these studies were “not powered to provide statistically meaningful comparisons between doses.” Resp. 11–12; Ex. 2071 ¶ 79 (stating a “POSA would have known that the study was not designed to provide statistically meaningful comparisons between doses, a point Dr. Weisman does not appear to dispute”); Ex. 1037, 155:11–160:20; Ex. 1003 ¶ 35 (stating “the data in van de Putte 1999 suggests that each dose was superior to placebo, but not that any dose was better or worse than another dose”). Kempeni 1999 discloses several clinical studies that utilized different dosing protocols. DE003 was one of those clinical studies. In the DE003 study, patients received 0.5 to 10 mg/kg of D2E7 intravenously “every two weeks” until DAS (Disease Activity Score) responses could be rated as “good.” Ex. 1011, 4 (emphasis added). Thus, far from criticizing, discrediting, or discouraging the person of ordinary skill from pursuing a biweekly regimen, Rau 2000 and Kempeni 1999 expressly disclose such dosing frequency. By the same token, Rau 2000’s conclusion that “D2E7, with a half-life of 12 days, can be administered every two weeks as an intravenous injection over 3-5 minutes or subcutaneously” does not specify any particular dosage level, much less exclude any dosage level described in Rau 2000 to provide a teaching away. See Ex. 2040, 8. Also, Kempeni 1999 does not criticize or disparage the effectiveness of the 0.5 mg/kg biweekly dose. Rather Kempeni 1999 expressly concludes that the biweekly treatment of D2E7 “in the dose range from 0.5 to 10 mg/kg was well tolerated.” Ex. 1011, 4; see Ex. 1037, 167:9–168:2; 170:8–19.” slip op. at 31

“The first step in construing a means-plus-function claim element is to identify the recited function in the claim element. Med. Instrumentation & Diagnostics Corp. v. Elekta AB, 344 F.3d 1205, 1210 (Fed. Cir. 2003). The second step is to look to the specification and identify the corresponding structure for that recited function. Id. A structure disclosed in the specification qualifies as “corresponding” structure only if the specification or prosecution history clearly links or associates that structure to the function recited in the claim. B. Braun Med., Inc. v. Abbott Labs., 124 F.3d 1419, 1424 (Fed.

“As we stated in our Decision on Institution, see Dec. 9–10, the recitation of “feed gas” in claim 35 does not imply necessarily the flow of gas. Dec. 11. We previously noted that the Specification of the ’652 patent describes the use of in-line gas valves 242, 244 that can control the flow of gas to the chamber (Ex. 1201, 8:3–5), and also describes pulsing feed gases 234, 236 to help generate excited atoms, including metastable atoms, in gap 212 (Ex. 1201, 8:3–5, 8:23–25). See Dec. 10–11. Therefore, we concluded that such control of the feed gas supports the notion that “feed gas” does not necessitate a “gas that is a flowing gas.” Id. Although we agree with Zond that this pulsed gas pressure embodiment can cause the gas to flow, it does not necessitate that the gas flow. We also previously stated that the Specification of the ’652 patent further states that feed gases may be introduced from multiple locations into the chamber. Id. (citing Ex. 1201, 8:1–3). We also stated that having multiple sources for feed gases does not support a construction that “a volume of feed gas” requires that the initial plasma and excited ions are generated from the same volume of feed gas, assuming that a particular volume of feed gas may be identified in such a process. Id. We discern no reason to modify our conclusions that the claim limitation does not imply necessarily the flow of gas nor does it require that the initial plasma and excited ions are generated from the same volume of feed gas.” slip op. at 14

“We agree with GlobalFoundries that Mozgrin does indeed disclose “means for super-ionizing the initial plasma proximate to the cathode assembly, thereby generating a high-density plasma.” In addition to the detailed explanation of how Mozgrin teaches creating a high density plasma by super-ionizing the initial plasma, see Pet. 4–17, 20–22; Ex. 1202 ¶¶ 84– 97, Dr. Kortshagen further explains in his Supplemental Declaration, in response to Zond’s arguments, that Mozgrin discloses power levels and pulse characteristics that fall within the ranges disclosed in the ’652 patent for first generating an initial plasma and then applying a high-power pulse to increase the plasma density. Reply 9 (citing Ex. 1216 ¶¶ 24–28). Dr. Kortshagen summarized his comparison of the ’652 patent and Mozgrin in the table below. Ex. 1216 ¶ 29. From this comparison of the applied power and resulting plasma density for the generation of an initial plasma and the comparison of the high-power pulse, including the pulse rise time and duration, and the resulting plasma density for the generation of the high-density plasma as shown in the table above, Dr. Kortshagen concludes that “Mozgrin expressly teaches generating a high-density plasma from an initial plasma under the conditions and parameters that the ’652 patent discloses will super-ionize the initial plasma to generate a high-density plasma.” Ex. 1216 ¶ 30; see also Ex. 1202 ¶ 87 (explaining that Mozgrin discloses embodiments and parameters that result in at least 75% of the neutral atoms in the plasma being converted to ions as required by claim 35). We also agree with GlobalFoundries, as Dr. Kortshagen explains, that Mozgrin expressly confirms super-ionizing the initial plasma to create a high density plasma. See Ex. 1216 ¶¶ 31–34. Dr. Kortshagen explains that Mozgrin discloses an ionization degree that approaches 100 percent for the transition between regime 2 and 3, an assessment with which Dr. Hartsough agrees. Id.; Ex. 1217, 112:12–124:23. At a level of ionization approaching 100 percent, Mozgrin discloses super-ionization of an initial plasma.8 See Ex. 1202 ¶ 88 (concluding “if Mozgrin’s neutral gas density were about 2.0 x 1015 atoms cm-3, then at least 75% of the neutral argon gas would have been ionized”).” slip op. at 34
