We adopt Petitioner’s definition as it appears to be consistent with the prior art’s demonstration of the level of ordinary skill in the art at the time of the invention. See Okajima v.

      “At this stage of the proceeding—and without a substantive response from Patent Owner—we determine Petitioner’s construction is consistent with the plain ordinary meaning of “about” and the intrinsic evidence. The claim recites that the carbon chain length of the bio-alkene is “about 5 to about 20 carbons atoms.” Ex. 1001, claim 1 (emphasis added). We agree with respect to the claimed range. See Cohesive Techs., Inc. v. Waters. Corp., 543 F.3d 1351, 1368 (Fed. Cir. 2008) (“When ‘about’ is used as part of a numeric range, the use of the word ‘about,’ avoids a strict numeric boundary to the specified parameter.”) (internal quotations omitted). In other words, the claim term “about 5 to about 20 carbon atoms” does not require precisely 5 to 20 carbon atoms. Moreover, we agree that a carbon atom in a compound is not divisible. Keeping these principles in mind, we find “about 5” at the lower end of the range encompasses a carbon chain length of 4 carbon atoms, and “about 20” at the upper end of the range encompasses a carbon chain length of 21. We also agree with Petitioner that the prosecution history of the related ’902 Application—which also claims the benefit of the ’985 Provisional and shares a virtually identical specification as the ’803 Patent— supports construing “about” to encompass one additional carbon atom, as evidenced by the amendment after allowance amending the term “carbon chain length of about 8 to about 20” to “carbon chain length of 7 to 20.” See Ex. 1006, 335 see also id. at 16, 23–63. Thus, the intrinsic evidence supports Petitioner’s construction and the plain ordinary meaning of “about.”” slip op. at 7

      “concerning the ’834 patent, the intrinsic evidence is minimally helpful in revealing an affirmative meaning for the claims’ “spacing(s)” terms. IPR2023-01151, Paper 12, 39–41. The Specification does not use the term “spacings” 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. And, portions of the prosecution record are arguably confounding. For example, the applicant distinguished claimed “spacings” from “tightly knitted fibers.” Ex. 2140, 1001 (suggesting a more “loosely defined fiber structure” may be covered); see also Ex. 1002, 29–30 (asserting the claimed design has “a lesser [fiber] density construction” compared to Walther). This begs the question, at what point does a cloth of “tightly knitted fibers” convert to a cloth having a “loosely defined” fiber structure that would come within the scope of the claimed “spacings?” The record does not answer. Applicant’s suggestion during prosecution that the claimed spacings between fibers are “intentionally placed” about the frame and not simply “the spacing that may be inherent” in fibrous cloths is also unavailing on this record in clearly defining the metes and bounds of the term. Ex. 1002, 28–29. Whether the alleged absence of “objective boundaries” for the term “spacings” supports a conclusion that the claims are invalid as indefinite would be a question for the court. Paper 11, 5 (arguing There is insufficient technical detail available to determine whether the SAPIEN 3 Ultra does or does not include “spacings” as claimed and we take no position on whether such device infringes any claim of the ’033 patent. that a conclusion that the claims are indefinite is “outside the Board’s [IPR] jurisdiction”).12 Notwithstanding the lack of any express claim construction for the “spacings” term from either party, claim 1 of the ’033 patent requires something more than just “spacings.” Claim 1 requires “spacings extending through a thickness of the sealing assembly that allow fluid to pass therethrough when the prosthetic heart valve assembly is in an undeployed state.” Ex. 1001, 22:11–15 (emphasis added). In other words, the spacings must allow fluid to pass through the sealing assembly’s thickness when the valve is undeployed. For reasons discussed below, we are not persuaded on this record that Petitioner is reasonably likely to prevail in showing that this limitation is met—particularly the fluid-passing element—in the proposed combinations of Spenser or Levi with Spenser II.” slip op. at 31

      “We, thus, find Dr. Brecker’s testimony more credible that “[i]t would, accordingly, be counterintuitive for a [POSA] to look to a device designed to occlude a blood vessel when designing a TAVR.” Id. ¶¶ 119–120 (testifying “[n]o [POSA] would look to this [occluder] design when considering a TAVR valve and . . . would further have concerns about the pro-thrombotic potential of the arrangement of fibers in Chuter”).

    • Obviousness (§103) › Motivation to combine / reasonable expectation of success › HindsightDecided for patent owner

      “Grounds 1 and 2 is based on the combination of either Levi and Spenser II, or Spenser and Spenser II. Yet Petitioner purports to modify Spenser II’s compressible material, or supplant it with something else, based on “porous” fabrics allegedly known elsewhere in the art, which art is not identified in the Petition itself as part of any asserted combination. Pet. 49. To see what specific modifications or combinations Petitioner might be suggesting, requires we look to three paragraphs of Dr. Buller’s Declaration, cited but not discussed by Petitioner, where eight additional references are mentioned. Ex. 1003 ¶¶ 157–159 (identifying Exs. 1106–1112, and 1129). This format is an improper incorporation-by-reference of argument and evidence that, had Petitioner wanted to pursue some other combination of asserted art beyond Levi, Spenser, and Spenser II, needed to be set forth explicitly in the Petition. 37 C.F.R. § 42.6(a)(3). Moreover, it leaves the record unclear and forces Patent Owner, the Board, and the public to guess at what combination(s) are, in fact, being urged. We also find that Petitioner’s position reveals a hindsight bias insofar as it suggests, with the aim of arriving at the claimed subject matter, removing Spenser II’s “sufficiently dense” and fluid impermeable compressible material (Ex. 2128 ¶ 222) in favor of some other sufficiently “porous” and fluid permeable material. Hindsight is further evidenced because Spenser II’s cited material is already described as being compressible and adapted to allow coagulation and tissue ingrowth—factors cited by Patent Owner as allegedly motivating a change to some other material. Ex. 1011 ¶ 145. Altogether, we find unpersuasive Petitioner’s position based on unspecified combinations of unasserted prior art to achieve benefits that Spenser II’s existing compressible material already provides.” slip op. at 36

This [POSA] would, where necessary, work with a medical device engineer to experiment with or manufacture a prosthetic heart valve.” Pet. 21 (citing Ex. 1003 ¶ 50). Patent Owner does not expressly contest Petitioner’s proposed definition or offer an alternative. See generally Prelim. Resp. For this Decision, we apply Petitioner’s proposed POSA level, which appears to be consistent with the level of skill shown in the prior art of record. See Daiichi Sankyo Co. v.

We need only construe terms that are in controversy and only as needed to resolve the matters in dispute. Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019). Petitioner contends that “[n]o terms of the ’310 patent require construction to resolve the patentability issues herein.” Pet. 19. Also, Petitioner contends, its “grounds are based on [Patent Owner’s] allegations that the ’310 patent covers Petitioner’s SAPIEN 3 Ultra valve and the scope of the claims asserted by [Patent Owner] in litigation.” Id. (citing Ex. 1122 (Complaint); Ex. 1123 (Infringement Contentions), 2, 262–476).11 Patent Owner does not propose any express claim construction. Instead, Patent Owner contends that the claims should be interpreted according to their ordinary and customary meaning. See, e.g., Prelim. Resp. 18–19, 35–36 (asserting that Petitioner’s mapping of the claims is, in respects, contrary to the “plain language” of the claims). 11 Petitioner identifies a claim construction order in related litigation where the district court construed an “outer frame” as a “self-expanding frame.” Pet. 19 (citing Ex. 1140, 17). We need not further construe the “outer frame” term here because Petitioner contends, without dispute, that the prior art discloses self-expanding frames. Id. at 19–20, 26. Moreover, Patent Owner states that it has disclaimed those claims reciting the term “outer frame” to reduce the number of issues before the Board. Prelim.

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for patent owner

      “We are unpersuaded. The language of claim 11 states the “sealing material is attached to the frame,” but also that it is the plurality of outwardly-extending “fibers” that maintain “contact with the frame along the height of the sealing material” whether the valve assembly is compressed or expanded. Supra Section II(D). Thus, according to this plain language, Petitioner must demonstrate that Spenser II’s identified fibers contact with the frame in its modification of Spenser or Levi—not just that some portion of Spenser II’s compressible material be attached to and contact the frame. On this record, we agree with Patent Owner that Petitioner’s contrary interpretation is “at-odds with the plain language of the claims.” Prelim. Resp. 18, 35. The cited excerpt from the prosecution history does not support Petitioner’s position that the “in contact” limitation is met if the sealing material—but not necessarily the fibers—contacts the frame. Petitioner cites an assertion by applicant during prosecution that modifying Levi’s valve so that the “sealing material” is in contact with the frame would not show that the claimed subject matter is obvious. Pet. 44 (citing Ex. 1002, 147–148). In its more complete context, however, applicant’s prosecution argument was made in furtherance of applicant’s repeated assertion that replacing Levi’s loosely-fit, “billowing” skirt with a tightly-held and bulky sleeve would change Levi’s principle of operation and make it too large and Resp. 35–36 (arguing applicant’s position is also “consistent” with claims’ plain language because, if Levi’s billowing skirt included outwardly-extending fibers, such fibers could not contact the frame along the skirt’s height when it billows out from the frame).15 Applicant’s argument does not rise to a concession that the “fibers in contact with the frame” limitation can be met so long as the sealing material contacts the frame. At best for Petitioner, the relevant prosecution history could be characterized as ambiguous; it does not justify rewriting claim 11’s plain language. See, e.g., Ex. 1002, 127–128 (earlier version of proposed amendment to application claim 31, reciting “the sealing material is in contact with the outer frame”), 138–139 (later version of the proposed and as-entered amendment, expressly changing the language to require “the plurality of fibers is in contact with the outer frame”).” slip op. at 28

      “We determine that Petitioner’s proffered reason to combine is sufficient for purposes of institution. Petitioner does not merely rely on the fact that Patel-2008, Mastrototaro, Shahmirian, and Causey are from same field of study or address the same problem. Instead, Petitioner points to Patel-2008’s express discussion of the utility of Mastrototaro, Shahmirian, and Causey’s teachings, together with the fact that all of the references apparently discuss different components of the same system (i.e., the Medtronic MiniMed continuous glucose monitoring system). See, e.g., Pet. 83–84; Ex. 1008 (Gross Decl.) ¶¶ 55, 70–71. On this record, we find for purposes of institution that Dr. Gross sufficiently establishes that “POSITAs would have been motivated to combine the sensor and transmitter of Mastrototaro, the communications of Shahmirian, and the monitor control programs of Causey to effectuate a diabetes management system with the monitoring, communication, and display functionalities disclosed in Patel-2008,” and “to convey as much accurate glucose information to a user as possible without providing inaccurate information.” Ex. 1008 (Gross Decl.) ¶¶ 190–93. Patent Owner’s argument that “nothing in Patel-2008 teaches or suggests incorporating these disparate teachings into a single system” (Prelim. Resp. 47–48) is unavailing. First, as noted above, Patel-2008 expressly teaches using in its system components described in Mastrototaro, Shahmirian, and Causey. Second, even if Patent Owner were correct that Patel-2008 lacks a teaching or suggestion to incorporate Mastrototaro, Shahmirian, and Causey’s teachings into Patel-2008’s system, Patel-2008 itself need not express a reason to combine. Rather, “[a]ny motivation to combine references, whether articulated in the references themselves or supported by evidence of the knowledge of a skilled artisan, is sufficient to combine those references to arrive at the claimed [invention].” Outdry Techs. Corp. v. Geox S.p.A., 859 F.3d 1364, 1370–71 (Fed. Cir. 2017).

      “CLAIM CONSTRUCTION Petitioner asserts that the claim language “angled capsule retaining elements” is a means-plus-function limitation under 35 U.S.C. § 112(6), where the function is “retaining an oral care capsule in a capsule receiving zone,” and the Specification’s corresponding structure is “angled bristles.” Pet. 8–11 (citing Ex. 1001, Abstract, 2:59–61, 2:65–67, 3:20–22, 4:64–5:13, 6:23–24, 6:26–30, 6:34–37, 7:19–23, 7:33–42, 9:61–10:1, 10:5–8, Figs. 1, 4, 5, 6; Ex. 1002, 224; Ex. 1008 ¶¶ 96–97). Petitioner argues that “angled capsule retaining elements” is non- structural and includes the generic placeholder nonce word “elements,” modified by functional language, and the claim does not further recite sufficiently definite structure for the elements. Id. at 8–9. Thus, it is Petitioner’s position that this limitation, although not using the presumptive word “means,” should be interpreted to be a means-plus-function limitation. Further, Petitioner argues that the only structure disclosed in the ’332 patent’s Specification that performs the claimed function is “angled bristles,” and that the Specification’s express mentioning of the term “retaining element” relates to a non-claimed feature having a different function, i.e., a movable back cover on the toothbrush to contain rear-loaded capsules in the head. Id. at 11 (discussing Ex. 1001, 5:10–19, 6:8–25; Ex. 1002, 228, 353–355). Patent Owner does not directly address Petitioner’s claim construction position. See generally Prelim. Resp. However, even if not addressing whether the claim language is a means-plus-function limitation, Patent Owner appears to agree with Petitioner that the claims’ scope includes angled bristles as the recited retaining elements, as disclosed in the Specification, although not expressly conceding at this point that the claims are limited to the disclosed angled bristles structure and equivalents under 35 U.S.C. § 112(6). See id. at 3–4 (citing paragraph 36 and Figure 1 of the application that issued as the ’332 patent). For the purposes of this institution decision, we find it unnecessary to construe any claim language because there is no dispute that the “angled capsule retaining elements” limitation recited by the claims includes angled bristles, even if it may not be limited to only such a structure (and its equivalents), and we find that angled bristles appear to be taught in the prior art, as discussed below. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)).

      “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. Ex. 2128 ¶ 222; see also Ex. 2002 (Brecker testimony) ¶¶ 42–45 (testifying, inter alia, that the description of a “tight fitted outer seal is . . . consistent with Spenser II’s Figure 22” and “knitted” is consistent with Buller’s testimony describing Spenser II’s compressible material as “velour-like woven or knitted” PET (citing Ex. 1003 ¶ 162; Ex. 2134 ¶ 56).

      “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.

      “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).

The residual lines of magnetic force of the magnet in the MRI apparatus pass through the access opening 14 generally normal to the scan of the Hall effect sensors. The passive sensors in the series 11 and 13 are sensitive to the magnetic force lines along one axis and produce a signal related to magnetic field strength. As a ferrous object (not shown) approaches the access doorway 12, the residual magnetic field is disrupted.

Based on these disclosures in the ’128 patent, we determine that the term “residual magnetic field” refers to the magnetic field that radiates outwardly from the MRI apparatus. This is substantially similar to Petitioner’s construction which acknowledges a “non-uniform magnetic field of the MRI apparatus passing through the open doorway.” Pet. 11.
