      “Petitioner, relying on the testimony of Mr. Brown, contends that a person of ordinary skill in the art (“POSA” or “POSITA”) as of the relevant date would be either: (1) a person with a B.S. in engineering or an equivalent field, with two-four years of academic or industry experience in aspiration embolectomy and thrombectomy or comparable industry experience who would, where appropriate, work or consult with others, including a physician, to develop embolectomy or thrombectomy devices; or (2) an interventional neurosurgeon with at least three years of experience developing and/or using medical devices in embolectomy or thrombectomy procedures, and who would, where appropriate, work or consult with others, including an engineer, to develop such a medical device. Pet. 11 (citing Ex. 1005 ¶ 48). Petitioner also contends that, “[a] person with less education but more relevant practical experience, or more relevant education but less practical experience, may also meet this standard.” Id. Patent Owner states that for purposes of its Preliminary Response, it accepts Petitioner’s proposed definition of POSA, but “reserves the right to propose its own description of a POSA if the Board institutes review.” Prelim. Resp. 8 n.3. For purposes of this Decision, we adopt Petitioner’s characterization because it is consistent with the level of skill in the art at the time of the invention as reflected by the ’402 patent and the cited prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

      “Petitioner provides a proposed construction for the term “[limited/limiting] to a positive amount of exit flow” recited in claims 3, 4, 13, and 15, as “the maximum permitted amount of positive exit flow in the distal direction, including no exit flow.” Pet. 15–16. Patent Owner asserts that “Petitioner’s proposed construction of ‘a positive amount of exit flow’ as ‘including no exit flow’ is plainly wrong.” Prelim. Resp. 9 (citing Pet. 15–16). Patent Owner also asserts that to the extent Petitioner “view[s] the claim term ‘flow in and out’ as encompassing only flow in or no flow at all, that would be plainly wrong too.” Id. Having evaluated the arguments and evidence before us on this record, we determine that construction of “[limited/limiting] to a positive amount of exit flow” is not necessary for purposes of this Decision. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (citing Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999) (“[O]nly those terms need be construed that are in controversy, and only to the extent necessary to resolve the controversy.”)). Turning to a different claim term, we note that neither party provided an explicit construction for the limitation in claim 1 of “control[ling] fluid address the proper claim construction for this term and to specifically discuss what is encompassed by “flow . . . out from the distal end.” We note that in the related cases (IPR2021-01466 and IPR2022-00608), we construed the term, “forward flow” to mean “an amount of liquid in the lumen that exits the distal end in the distal direction that is greater than 6 microliters of fluid.” Ex. 2007, 15; Ex. 2011, 13–14. Upon review of the parties’ arguments and the evidence of record, we determine that no terms require express construction for purposes of this Decision.

    • Obviousness (§103) › Graham factors (scope of art, differences, level of skill)Instituted

      “c) Analysis On the current record, we are persuaded that Petitioner has demonstrated a reasonable likelihood that the subject matter of claim 1 would have been obvious over the combined disclosures of Yang and Mullins. First, Patent Owner asserts that Yang does not disclose the limitation of “a controller . . . to control fluid flow in and out from the distal end.” Prelim. Resp. 21– 32. On the current record, we agree with Patent Owner that introducing a positive pressure pulse such as through the water hammer effect does not necessarily mean that there will be an overall distal end. See Ex. 2001 ¶¶ 53–54; Ex. 2005 ¶ 60; Ex. 2007, 51 n.12. This is especially true if an overall vacuum state is maintained in the catheter. See Ex. 2001 ¶ 56; Ex. 2007, 43; Ex. 2010, 125:11–18. Further, on the current record, we credit the testimony of Patent Owner’s declarant, Mr. Culbert, that to have flow out of the catheter’s distal end when it is in a patient, the pressure in the catheter needs to exceed mean arterial pressure. See Ex. 2001 ¶ 59; Ex. 2010, 126:15–21. Therefore, on the current record, we agree with Patent Owner that Yang may not explicitly disclose flow out from the distal end of the catheter. Whether Yang alone renders this limitation obvious may be explored further on a full trial record; however, because this limitation appears to be taught by Mullins and Petitioner has shown on this record that a POSA would have been motivated to combine the disclosures of Yang and Mullins, we are sufficiently persuaded that Petitioner has met its burden to show a reasonable likelihood that this limitation is rendered obvious by the combined disclosures of Yang and Mullins.” slip op. at 18

Petitioner argues that such a person of ordinary skill would also have at least three years of experience conducting research concerning endocrine disorders, including CAH or other adrenal disorders. Id. Patent Owner does not expressly contest this definition of a person of ordinary skill in the art in its Response.

      “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.

    • Claim Construction › Intrinsic evidence (Phillips canons) › Preamble limiting or notPreamble limitingDecided for petitioner

      “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. Cir. 2021). We consequently reject Patent Owner’s proposed construction that the language of the preamble reciting a “method for treating an angiogenic eye disorder” requires not only an intent to treat, but, additionally, a high degree of efficacy on par with monthly Lucentis.

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed petitioner constructionDecided for petitioner

      “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). 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.

      “Level of Ordinary Skill in the Art In determining the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC, Inc., 57 F.3d 1573, 1579 (Fed.

Here, Petitioner asserts that an ordinarily skilled artisan “would typically have an advanced degree, such as a Ph.D., with research experience in genomics, molecular biology, bioinformatics, or a related field, or could have less education but significant professional experience in one or more of these fields.” Pet. 8–9 (citing Ex. 1002 ¶ 38).

      “1. “Sequence Reads” Petitioner argues that, for purposes of this Decision, no claim term needs specific construction beyond its plain and ordinary meaning. Pet. 10–11. Petitioner, however, seeks to provide context for understanding the scope of the term “sequence reads.” Specifically, Petitioner contends that “sequence reads” are produced by sequencing at least some of the tagged strands, whereas “consensus sequences” are generated by collapsing sequence reads.

      “We disagree with Patent Owner’s proposed construction of the terms “paired sequence reads” and “unpaired sequence reads.” Even though the ’951 patent Specification discloses grouping sequence reads “sharing a unique set of SMI tags” into paired families,4 “[t]he written description part of the specification itself does not delimit the right to exclude. That is the function and purpose of claims.” Phillips, 415 F.3d at 1312 (“[T]he claims of a patent define the invention to which the patentee is entitled the right to exclude.”). Here, claim 1 explicitly defines the terms “paired sequence reads” and “unpaired sequence reads.” Indeed, in the context of paired versus unpaired sequence reads, claim 1 specifies that the complementarity is related to the “original parent polynucleotide molecule,” and not the duplex tags. For example, claim 1 recites that “each unpaired read represents a first tagged strand having no second differently tagged complementary strand derived from an original parent polynucleotide molecule represented among said sequence reads in said set of sequence reads.” Ex. 1001, 37:50–55 (emphasis added).

      “Claim 1 defines the terms “paired sequence reads” and “unpaired sequence reads” based on the complementarity of the target sequence strands derived from the “original parent polynucleotide molecule.” Ex. 1001, 37:46–55. As explained above, we reject Patent Owner’s contention that a sequence read is considered unpaired solely based on the complementarity of the SMI tags. See supra Section II.C.2. Due to the “errors introduced during sample preparation and sequencing” (Ex. 1029 ¶ 5), there are four outcomes when determining the complementarity of the sequence reads of two strands of SMI-linked target sequence: (1) the first SMI tag and the first strand target sequence are complementary to the second SMI tag and the second strand target sequence, respectively; (2) the first SMI tag is complementary to the second SMI tag but the first strand target sequence is not complementary to the second strand target sequence; (3) the first SMI tag is not complementary to the second SMI tag but the first strand target sequence is complementary to the second strand target sequence; and (4) the first SMI tag is not complementary to the second SMI tag, and the first strand target sequence is not complementary to the second strand target sequence. It is undisputed that Schmitt groups sequence reads into paired families based on the SMI tags, and Schmitt only considers sequences in which “information from both DNA strands was in perfect agreement.” Ex. 1029 ¶¶ 14, 96; PO Resp. 18. Thus, among the four outcomes, only scenario (1), in which both the SMI tags and the target sequences are complementary, represents a “paired sequence read,” which claim 1 defines as corresponding to “sequence reads generated from a first tagged strand and a second differently tagged complementary strand derived from an original parent polynucleotide molecule.” Ex. 1001, 37:46–50.

      “during prosecution. Pet. 18, 99. According to Petitioner, Spenser II never describes its compressible material as including “tightly knitted fibers” and a POSA would, instead, have understood Spenser II’s compressible material as comprising “loose, porous materials.” Pet. 18, 99. We agree with Petitioner that the phrases “tightly knitted” and “tightly knitted fibers” do not appear in Spenser II. At the same time, neither does Spenser II describe its compressible material as being “loose” and “porous.” Notably, in prior proceedings before the Board, Petitioner’s declarant Dr. Buller testified that Spenser II’s compressible material “includes a plurality of PET fibers on the inward-facing surface of the compressible material” (i.e., the “base layer” and alleged “second plurality” of fibers here; Paper 9, 5), that is “sufficiently dense to prevent blood from leaking through the cloth/fabric.” Ex. 2128 ¶ 222; see also Ex. 2122, 20:2–22:18 (testifying that “nonporous” as used in the Specification means “that fluid would not pass through it” and such fluid includes “all components of blood”). We find that Dr. Buller’s description of Spenser II as having a dense, blood impermeable base layer is, on balance, more consistent with applicant’s characterization of Spenser II as having an arrangement of “tightly-knitted fibers”—even if some imagined or microscopic spaces between fibers might still exist in a base layer.

      “Altogether, the parties’ alleged “plain meaning” yet otherwise undefined interpretation of the “spacing” limitations leaves the Board with insufficient clarity about what the claimed “spacing” means in the affirmative. Paper 9, 3 (arguing “plain meaning”); Paper 11, 3 (arguing applicant’s arguments are in “full harmony with the plain meaning”). The intrinsic evidence is minimally helpful: the Specification does not use the term “spacing” in relation to the positioning of adjacent fibers; the drawings might be helpful but neither party proposes a specific construction that is reliant on them.15 The prosecution history provides clues, but portions of the prosecution record are arguably confounding. The applicant distinguished 15 For example, Dr. Brecker, in support of Patent Owner’s argument, identifies several of the patent drawings and testifies that, “as is particularly clear in Figure 13 (but also present elsewhere), there are gaps and spaces between the fibers that extend to the frame” and then proceeds to testify that prior art, like Spenser II’s compressible material, “bears no resemblance” to the “exemplary” spacings identified in prosecution. See, e.g., Ex. 2002 ¶¶ 42–43. Dr. Brecker’s articulation of a “spacing” does not seem to add anything meaningful beyond the language of the claim as written. And, simply comparing the patent drawings to the prior art drawings presumes a sort of “know-it when you see it” interpretation—it is not an affirmative construction for a “spacing” as claimed. the claimed “spacings” from “tightly knitted fibers.” Ex. 1002, 1001. At what point, however, does a cloth of “tightly knitted fibers” qualify as more “loosely defined” and come within the scope of the claimed “spacing?”16 Id. The applicant also described the “spacing” in semi-functional terms based on “advantages” provided by the claim feature. See, e.g., id. (asserting, e.g., that the spacing permits “expansion and contraction” with “lesser rigidity”); see also id. at 1133, 1140 (asserting, e.g., “reduce[d] restrictions” and avoidance of “restrained valve foreshortening” with the then-claimed “openings”). It is not, however, evident where the Specification supports such “advantages”—no citations were given in prosecution. And, in prosecution of related applications, applicant argued, for example, that “[w]hile all fibers have some degree of being spaced-apart, the construction from Applicant’s claimed invention clearly requires some level more spacing.” Ex. 1149, 13–14 (assertion differences over “Dehdashtian” (alias to Spenser II)) (emphasis added).

      “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. We find that, as in Eli Lilly, although the claims “encompass a clinical result, they do not require such a result.” Eli Lilly, 8 F.4th at 1343. We consequently reject” slip op. at 35

      “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. Ex. 1001, col. 3 ll. 34–44. Petitioner also notes that the Specification further explains that “the immediately preceding dose” means “in a sequence of multiple administrations, the dose of VEGF antagonist which is administered to a patient prior to the administration of the very next dose in the sequence with no intervening doses.” Pet. 24 (citing Ex. 1001, col. 3, ll. 54–59; Ex. 1002 ¶¶ 44–45). 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

      “As Petitioner states, Patent Owner relies upon these Exhibits as objective secondary evidence of non-obviousness. See, e.g., PO Resp. 65– 69. However, and as we explain below, because we find that the challenged claims are anticipated by Dixon, we do not reach Patent Owner’s arguments that the claims are non-obvious (Grounds 4–6) or its contentions regarding secondary considerations of non-obviousness. See Cohesive Techs., Inc. v. Waters Corp., 543 F.3d 1351, 1364 (Fed. Cir. 2008) (holding that “secondary considerations are not an element of a claim of anticipation”). Consequently, we dismiss Petitioner’s motion to dismiss the Financial Documents as moot.” slip op. at 10

      “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. 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. Id. at 28–29 (citing Ex. 1002 ¶¶ 27–29; Ex. 1003 ¶¶ 21–25). Patent Owner does not expressly contest this definition of a person of ordinary skill in the art in its Response. Because we find Petitioner’s definition to be consistent with the level of skill in the art (see, e.g., Exs. 1006, 1020), we adopt Petitioner’s definition.” slip op. at 52
