“We construe each claim “in accordance with the ordinary and customary meaning of such claim as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent.” 37 C.F.R. § 42.100(b) (2019). Under this standard, claim terms are generally given their plain and ordinary meaning as would have been understood by a person of ordinary skill in the art at the time of the invention and in the context of the entire patent disclosure. Phillips v. AWH Corp., 415 F.3d 1303, 1313 (Fed. Cir. 2005) (en banc). Only those terms in controversy need to be construed, and only to the extent necessary to resolve the controversy.

“these drawbacks in a petition directed to a related patent, where Petitioner argued that “a significant portion of the available space within [Kobayashi’s] cell is reduced by the process of crimping the cell closed.” Id. at 46 (quoting Ex. 2008, 2–3). Patent Owner argues that “Petitioner fails to explain why the beaded-over Kobayashi housing Petitioner and its same expert disparaged in another petition would be used in the present combination of references proposed in this Petition.” Id. at 48. Patent Owner’s argument raises an issue about a tradeoff that a person of ordinary skill in the art might or might not have made: under Petitioner’s proposed combination of teachings, it may be that a person of ordinary skill in the art would have had to accept reduced internal volume, and the consequent reduction in energy capacity, as the price of avoiding short circuits. The question of whether this tradeoff existed and, if so, whether a person of ordinary skill in the art would have made the tradeoff is a factual issue best resolved on the full record to be developed at trial. Patent Owner also argues that a person of ordinary skill in the art would not have replaced Higuchi’s housing with Kobayashi’s to reduce the risk of short circuits. Prelim. Resp. 48–49. Patent Owner points to Petitioner’s arguments in a related case regarding claims 27 and 28 of U.S. Patent No. 11,024,905, where Petitioner argues that it would have been obvious to add Kubota’s insulation tape to Higuchi’s leads 11 and 12, and Patent Owner argues that a similar modification here “could reduce such risk Kobayashi’s housing.” Id. at 48–49 (citing Ex. 2042, 2–4). According to Patent Owner, if “Petitioner and its expert are correct that a [POSITA] would have been motivated to adhere an insulation strip to both sides of Higuchi’s lead, it would not be necessary to change Higuchi’s housing for Kobayashi’s beaded-over housing to reduce the risk of short circuits.” Id. at 49. The fact that the prior art may suggest that some combination of techniques is more desirable than, or otherwise preferred over, the combination on which Petitioner relies does not preclude a finding that the challenged claims would have been obvious over Petitioner’s proposed combination. See Bayer Healthcare Pharms., Inc. v. Watson Pharms., Inc., 713 F.3d 1369, 1376 (Fed. Cir. 2013) (quoting In re Fulton, 391 F.3d 1195, 1200 (Fed. Cir. 2004)). Thus, we have considered Patent Owner’s arguments, and although they cast doubt on Petitioner’s contentions and create a genuine issue of material fact, we are persuaded, on this record, that Petitioner provides sufficient reasoning with rational underpinning to support a motivation to combine the teachings of Higuchi and Kobayashi as proposed. Pet. 21–33. Specifically, Petitioner sufficiently establishes, for purposes of institution, that a POSITA would have had reason to modify Higuchi’s cell to use Kobayashi’s housing in order to reduce the risk that the cell would short circuit. Id. at 23–27. Whether Petitioner sufficiently establishes this issue to prove unpatentability is an issue we need not, and do not, resolve on this preliminary record. We invite the parties to develop these arguments further at trial, to the extent permitted under our rules.” slip op. at 20

A reference is considered publicly accessible if it was “disseminated or otherwise made available to the extent that persons interested and ordinarily skilled in the subject matter or art, exercising reasonable diligence, can locate it.” Id. at 1355–56 (citing In re Wyer, 655 F.2d 221, 226 (CCPA 1981)). Under at least some circumstances, a reference may be a printed publication under § 102(b) if it was “displayed to the public,” even if it “was not later indexed in any database, catalog, or library.” In re Klopfenstein, 380 F.3d 1345, 1350 (Fed. Cir. 2004). There are several factors relating to whether such a display is sufficient to constitute a printed publication, including “the length of time the display was exhibited, the expertise of the target audience, the existence (or lack thereof) of reasonable expectations that the material displayed would not be copied, and the simplicity or ease with which the material displayed could have been copied.” Id. In addition, distribution of a reference at a professional conference may, under at least some circumstances, constitute sufficient dissemination to show public accessibility.

As discussed above, we find that both references were distributed sufficiently at professional conferences to be publicly accessible at the time of those conferences. By virtue of this public accessibility, both Voswinckel JESC and Voswinckel JAHA were printed publications early enough to qualify as prior art under 35 U.S.C. § 102(b). G.

“The express language of claim 1 requires no solubility threshold, and dependent claim 10 of related U.S. Patent No. 10,288,620 B2 demonstrates that, where a solubility threshold was intended by the inventors of these patents, they knew how to expressly set forth that threshold in the claims. Compare Ex. 1004, 222:47–49 (“capable of imparting solubility in water”), with Ex. 1005, 218:12–14 (“The method according to claim 1, wherein each R is a non-ionic side group capable of imparting solubility in water in excess of 10 mg/mL.”). Thus, the claim language does not support applying a particular solubility threshold in claim 1. As noted by Patent Owner, the written description of the ’648 patent explains that “each R is independently a non-ionic side group capable of imparting solubility in water in excess of 10 mg/mL.” Ex. 1004, 2:21–22; Prelim.

“Here, Patent Owner filed a statutory disclaimer of claims 11–17 of the ’417 patent. Prelim. Resp. 1–2; Ex. 2019. Based on our review of Exhibit 2019, we determine that a disclaimer of claims 11–17 of the ’417 patent under 35 U.S.C. § 253(a) has been filed with the Office as of October 5, 2022. Based on the information in the public record, we find that the disclaimer complies with the above-listed requirements of 37 C.F.R. § 1.321(a). Because claims 11–17 have been disclaimed under 35 U.S.C. § 253(a), in compliance with 37 C.F.R. § 1.321(a), we do not reach challenges to claims 11–17.

“be lifted for each patent for which the petition is denied. As noted above, there are six related petitions at the Board involving the patents before the court. The district court stayed the litigation “pending resolution of the IPR proceedings that have been instituted on the patents at issue in this case.” Ex. 2006, 2. Regarding the length of the stay, the district court explicitly ordered the parties not to use continuance of the fact discovery to October 28, 2022 “as grounds for . . . opposing institution of any post-grant proceeding.” Ex. 2007, 2. Regarding when the stay will be lifted, the order merely gives Patent Owner the opportunity to “seek to lift the stay as to any patents that are not instituted for review.” Ex. 2006, 2 (emphasis added). But we decline to speculate whether the district court would grant such a motion directed only to one of the six patents. Among the reasons warranting a stay of the litigation, the district court found “IPR has the potential to streamline issues for trial” and “the resources the parties will need to expend for experts could be significantly impacted by the outcome of any instituted IPR proceedings.” Id. Thus, the litigation is stayed pending the outcome of the six related proceedings, not merely the outcome of this institution decision, and the district court stayed the litigation for the explicit purpose of gaining efficiency and avoiding duplication of efforts by letting this inter partes review proceed to its conclusion first.14 See Prelim. Reply. 4–5. While Patent Owner may seek to lift the stay as to any patent for which institution is denied, the grant of any such request is uncertain. Accordingly, this factor strongly weighs against discretionary denial of institution.” slip op. at 15

- Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Decided for patent owner
“The express language of claim 1 requires no solubility threshold, and dependent claim 10 demonstrates that where a solubility threshold was intended by the inventors of the ’620 patent they knew how to expressly set forth that threshold in the claims. Compare Ex. 1005, 213:26–27 (“capable of imparting solubility in water”), with id. at 218:12–14 (“The method according to claim 1, wherein each R is a non-ionic side group capable of imparting solubility in water in excess of 10 mg/mL.”). Thus, the claim language does not support applying a particular solubility threshold in claim 1. As noted by Patent Owner, the written description of the ’620 patent explains that “[i]n some embodiments, each R is independently a non-ionic side group capable of imparting solubility in water in excess of 10 mg/mL.” Id. at 54:2–10; Prelim. Resp. 12–13. This solubility threshold, however, is not in claim 1, and we decline to import such a limitation from the written description into claim 1 absent compelling reasons for doing so. See SciMed Life Systems, Inc. v. Advanced Cardiovascular Systems, Inc., 242 F.3d 1337, 1340 (Fed. Cir. 2001) (explaining that “reading a limitation from the written description into the claims” is “one of the cardinal sins of patent law”); see also Thorner v. Sony Comp. Entm’t Am., LLC, 669 F.3d 1362, 1366 (Fed. Cir. 2012) (“It is likewise not enough that the only embodiments, or all of the embodiments, contain a particular limitation. We do not read limitations from the specification into claims; we do not redefine words.”). In view of the foregoing, we construe the term “non-ionic side group capable of imparting solubility in water” to not include any particular numeric solubility threshold.13” slip op. at 12

“Petitioner’s position is persuasive. We agree that documents from the Japanese Patent Office are self-authenticating official government documents. The technical issues regarding missing pages in the originally filed version of the document do not cause us to question authenticity. We also agree that Petitioner uses the documents to establish what the documents teach rather than establishing the truth of what the documents teach. In Reply, Patent Owner argues that Petitioner relies on the date printed on the document to prove up the truth of when the document was published. Mot. Excl. Reply 1–2. To the extent this is the case, an exception to hearsay applies because the document is a record of a public office. Fed. R. Evid. 803(8)(B) (a record of public office is an exception to the hearsay rule if the opponent does not show that the source of information or other circumstances “indicate a lack of trustworthiness”). Here, Patent Owner does not persuasively demonstrate a lack of trustworthiness; Patent Owner does not identify any substantively meaningful distinction in the missing pages of the originally filed document and does not identify any evidence to suggest that the missing pages were anything more than a harmless clerical error.

“Petitioner’s proposal is too broad. PO Resp. 8. For example, a person who merely installs solar panels for three years (satisfying “professional experience in solar energy”) while having some familiarity with module manufacturing would not be of ordinary skill in the design aspects of the ’060 patent as, for example, reflected by the claims at issue and the ’060 patent’s text and figures. See, e.g., Ex. 1101, Figs. 2a, 2b, 3a, 3b, 4a, 4b, 3:22–7:44. On the other hand, we also determine that Patent Owner’s proposal is too narrow. A person could, for example, have ordinary skill in the art of the ’060 patent by virtue of non-professional experience (for example, academic experience). When assessing relevant experience, research work done for a university (beyond mere classroom study) would have been just as valuable as research work done for a corporation. Also, ordinary skill in the art could be demonstrated by work that requires understanding of the ’060 patent’s field even if not “designing, developing, and/or researching” in the field itself We, thus, determine that a person of ordinary skill in the art of the ’060 patent would have been someone with a bachelor’s degree in electrical engineering, applied physics, or the like, and at least two years of (a) experience designing, developing, and/or researching in the field or (b) experience in solar energy that required an understanding of the ’060 patent’s field.
