“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

“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

“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

“For these reasons, we do not find persuasive the testimony of Patent Owner’s expert, Dr. Dobs, that: By describing adjustments of dosing protocols to achieve at least a 10% reduction from baseline, and describing this use of tildacerfont as just one embodiment of the claimed use of the entire well-known, well-characterized, and discrete class, the specification reasonably conveyed to a POSA that the invention extended to the particularly claimed use of the entire recited class. Ex. 2014 ¶ 87. 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. Moreover, the challenged claims recite only “a CRF1 receptor antagonist or a pharmaceutically acceptable salt thereof,” the scope of which also encompasses the much larger (and, according to Williams) much more effective large-molecule (peptide) CRF1 receptor antagonists, about which the Specification is entirely silent.

“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).

Printed matter that is functionally related to its substrate is given patentable weight. Id. (citing DiStefano, 808 F.3d at 850).

“arguments and the evidence, we find that the Specification expressly defines the terms “initial dose,” “secondary doses,” and “tertiary doses.” The Specification states, 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. Ex. 1001, 3:31–38 (emphasis added). 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,” and that “the ‘tertiary doses’ are the doses which are administered after the secondary doses.” Ex. 1001, 3:31–38 (emphasis added).

The angiogenic eye disorders in patients. See, e.g., id. at 1:18–20, 63–66, 2:23– 27; 3:19–20; 5:11–13. 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. As the Federal Circuit explained in Boehringer Ingelheim Vetmedica, Inc. v. Schering-Plough Corp., 320 F.3d 1339 (Fed. Cir. 2003), “preamble language will limit the claim if it recites not merely a context in which the invention may be used, but the essence of the invention without which performance of the recited steps is nothing but an academic exercise,” and that this principle frequently holds true for method claims. Id. at 1345 (citing Griffin v. Bertina, 285 F.3d 1029, 1033 (Fed. Cir. 2002)). We find that such is the case here. 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 Federal Circuit case law regarding statements of intended purpose in claims directed to method of using compositions, and 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.”” slip op. at 17

“We begin by noting that the claims do not recite any dosage amounts or that the administered doses are “therapeutically effective” separately or cumulatively. Instead, the claimed method focuses on treating an angiogenic eye disorder with a specific compound, i.e., a VEGF antagonist, based on a specific temporal regimen, i.e., sequentially administering an initial dose, followed by a prescribed time frame for secondary and tertiary dose(s). As discussed above, we determined that the preamble limits the claims in terms of requiring the doses of VEGF antagonist administered to be for the purpose of treating an angiogenic eye disorder in a patient. We find that the intrinsic evidence supports finding that it is the administration of the VEGF antagonist to such patient for the purpose of providing an improvement of or beneficial effect on their angiogenic eye disorder that satisfies the “treating” portion of the preamble. regarding the “Amount of VEGF Antagonist Administered.” See Ex. 1001, 6:29–7:14. In that discussion, the Specification explains, The amount of VEGF antagonist administered to the patient in each dose is, in most cases, a therapeutically effective amount. As used herein, the phrase “therapeutically effective amount” means a dose of VEGF antagonist that results in a detectable improvement in one or more symptoms or indicia of an angiogenic eye disorder, or a dose of VEGF antagonist that inhibits, prevents, lessens or delays the progression of an angiogenic eye disorder. Id. at 6:48–55 (emphasis added). That description, along with the absence of the phrase “therapeutically effective” in the claims,11 signals for us the inventors’ intention to not limit the claims to the administration of doses that ultimately prove to be therapeutically effective in a given patient. Instead, the Specification describes administration of VEGF antagonist doses for treating angiogenic eye disorder in a manner that encompasses doses that result in disclosed improvements and benefits, referred to as “therapeutically effective amounts,” and doses that do not. Indeed, as guidance, the Specification discloses that “a therapeutically effective amount can be from about 0.05 mg to about 5 mg,” without any guarantee that any particular dosage regimen administered within that range of dosage amounts will necessarily be “therapeutically effective,” and without limiting the treatment methods based upon such results. Ex. 1001, 6:55–58 (emphasis added).” slip op. at 19
- Claim Construction › Intrinsic evidence (Phillips canons) › Lexicography (patentee as own lexicographer)Term construed petitioner constructionDecided for petitioner
“arguments and the evidence, we find that the Specification expressly defines the terms “initial dose,” “secondary doses,” and “tertiary doses.” The Specification states, 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. Ex. 1001, 3:31–38 (emphasis added). 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,” and that “the ‘tertiary doses’ are the doses which are administered after the secondary doses.” Ex. 1001, 3:31–38 (emphasis added). Patent Owner has not directed us to any portion of the Specification or other persuasive evidence that supports adding an efficacy requirement to that definition.” slip op. at 24

“We are not persuaded by Petitioner’s argument that the challenged Exhibits are not authenticated. Federal Rule of Evidence 901 sets a relatively low bar for authentication. See Comcast, 2020 WL 4687062, at *28. Rule 901(a) states: “To satisfy the requirement of authenticating or identifying an item of evidence, the proponent must produce evidence sufficient to support a finding that the item is what the proponent claims it is.” Fed. R. Evid. 901(a). By way of example, Rule 901(b)(1) states that a witness with knowledge can provide authenticating testimony that an item is what it is claimed to be. Fed.

“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
