“Patent Owner argues that the ’105 patent claims were “fully supported as of the filing date of at least the ’606 Application . . .

PO Resp. 63–65; PO Sur-reply 26–29. Patent Owner’s argument is persuasive. The ’606 Application discloses: [W]hen the toilet fill valve 100 is open and water flows from the water inlet 103 to the water outlets 106 and into a toilet tank, an amount of water is also supplied to the bowl fill valve inlet 113 that flows through the bowl fill valve 109 and out the bowl fill valve outlet 116. By virtue of the manual setting of handle 119 of the bowl fill valve 109, the flow of water through the bowl fill valve 109 is regulated. In this manner, the flow of water is regulated so that enough water flows out of the bowl fill valve 109 to fill a toilet bowl without wasting any water down a drain. seen from the passage above, the ’606 Application discloses regulating an amount of water supplied to a toilet bowl using a valve (i.e., a water flow regulator). Ex. 2013 ¶ 288. Further, the ’606 Application states: The bowl fill valve 109 may be, for example, a ball valve, a gate valve, a globe valve, a plug valve, a diaphragm valve, a butterfly valve, a needle valve, a sliding gate, a quick turn valve, a knife valve or any other appropriate type of valve as can be appreciated by those with ordinary skill in the art.” slip op. at 42

“limited to Patent Owner’s proposed “from about 50 Daltons to about 1,500 Daltons.” The cited evidence relied on in the Pomper Declaration to define “low molecular weight” as a term well accepted in the chemical arts relates to metabolomics and metabolites. See Ex. 1002, 169, (specifically, ¶ 17 of Dr. Pomper’s declaration). Patent Owner admits that Dr. Pomper’s testimony is about molecules that differ from the claimed imaging and radiotherapeutic agents targeting FAP-α, but argues that the testimony is still relevant for purposes of explanation. Prelim Resp. 21. While it may be relevant, the testimony is not persuasive in light of the Specification. We find the uncontested fact that several of the B moieties alone—without the A moiety or L linker—specifically identified in the ’233 patent fall outside of Patent Owner’s proposed definition persuasive, as we normally do not interpret claim terms in a way that excludes examples disclosed in the specification. See, e.g., Verizon Servs. Corp. v. Vonage Holdings Corp., 503 F.3d 1295, 1305 (Fed. Cir. 2007) (rejecting proposed claim interpretation that would exclude disclosed examples in the specification). The cases cited by Patent Owner supporting that a claim term may be construed to exclude embodiments where the prosecution history supports such construction are factually distinguishable from the instant case as they regard instances of specific prosecution history disclaimer, clear prosecution disavowal, or relate to a specific definition of the terms in the Specification for the term being construed. Here, “low molecular weight” is not defined in the Specification, but, as Petitioner argues (see Pet. 21–25) is characterized as “demonstrat[ing] faster pharmacokinetics and a higher specific signal within clinically convenient times after administration” and that it “can be synthesized in radiolabeled form more easily.” Ex.1001, 13:33–50, 14:56– 16:14, 17:9–20.

The disclosure need only reasonably convey to a POSA that the inventor had possession of the subject matter in question, even if every nuance of the claims is not explicitly described in the specification.

“1. Analysis of Claims 1–18 Schuster is available as prior art if the ’993 patent is only entitled to its January 27, 2014, filing date and not entitled to claim priority to earlier filing dates of the parent applications. On its face, the ’993 patent claims priority to a number of earlier parent applications, including Application No. 12/786,904 (the ’904 Application) filed May 25, 2010, and the Application code 63. Petitioner contends that the ’993 patent is not entitled to claim priority to the filing date of the earlier parent applications, and, thus, Schuster, a parent application of the ’993 patent, is available as prior art.15 Pet. 91–92. Petitioner alleges that the earlier parent applications, specifically Application No. 12/786,904 (the ’904 Application), do not provide written description support for the ’993 patent’s claim term “water flow regulator.” According to Petitioner, “water flow regulator” encompasses both adjustable devices for restricting the flow of water (i.e., valves) and fixed devices for restricting the flow of water (i.e., restrictors). Pet. 15. Petitioner contends that the ’904 Application does not provide support for water flow restrictors and, thus, does not provide support for the broader claim term water flow regulators. Id. at 14–15, 91–92. Petitioner argues that only adjustable water flow devices (i.e., valves) are supported by the ’904 Application. Id. Petitioner, thus, asserts that earliest effective filing date of the ’993 patent’s claims is the filing date of its application, January 27, 2014. Id. at 92. To be entitled to claim the benefit of an earlier filing date under 35 U.S.C. § 120 each application in the priority chain must comply with the written description requirement of 35 U.S.C. § 112(a). See Hollmer v. 14 The parties do not dispute that the ’993 patent and the earlier parent applications, including the ’904 Application and the ’606 Application, have the same pertinent portions of their specifications.

“Here, although the ’286 patent distinguishes “account data” from “transaction data” in the embodiment of Figure 11, the “transaction data” is submitted by the user to perform a series of banking transactions after manually entering a PIN code, whereas the “account data” is stored on the server, and the token information is accepted from the smart card’s 1001, 10:12–18, 10:30–35, 10:40–42, 11:21–22, 11:65–12:4, 12:22–36. Thus, the claimed “transaction data” that is “accepted . . . from an output interface of a transaction card” and “accepted . . . from a transaction card at an input interface of the card reader,” as recited in independent claims 1 and 3, comprises data stored on and read from a card, such as an ID number, password, authentication information, or session information, that can be used to facilitate a transaction.

“As discussed above in Section II.C, we construe the term “transaction data” as encompassing any data involved in a transaction, including account data. Again, we emphasize that claim 1 requires that the transaction data is accepted by the card reader from an output interface of the transaction card. Cho provides that card reader 230 reads a digital signal that includes account information of card 130 whereby the account information “may include at least one of an account number, a card expiration data, etc.” Ex. 1005, 5:54–58. We further agree with Petitioner that to the extent “transaction data” is for the purpose of conducting banking transactions, Cho’s account data of a credit card number and expiration date can perform that purpose. Patent Owner’s arguments that the transaction data cannot be “static” and that claim 1 requires “processing actual transaction-specific data” are not commensurate with the scope of the claim 1. The claim does not recite any limitations that the transaction data be dynamic or “not static,” nor does it recite any processing of the transaction data outside of using it to “facilitate transactions.” Petitioner has shown that Cho teaches the claimed transaction data.” slip op. at 55

“In contrast, Patent Owner’s declarant, Mr. Williams, testifies based on his “experience[,] that tenons are generally included in the larger portion of two table top portions.” Ex. 2006 ¶ 55. However, Mr. Williams’ experience does not explain why an ordinary observer would understand such functional and ornamental characteristics of tenon and hole arrangements. Id. Nor does this testimony proclaim that tenons must be in the larger of two table top potions. Indeed, even considering an ordinary observer imbued with Mr. Williams’ level of expertise and experience, and understanding for instance that it may be more likely that the wider portion includes tenons, this does not resolve the glaring inconsistency that Figure 1 illustrates holes and Figure 8 illustrates tenons. In other words, Mr. Williams’ “experience” does not resolve the visible tension that, on one hand, Figure 1 illustrates holes as part of the claimed ornamental design in the wider portion of the table top, and on the other hand, Figure 8 illustrates tenons as part of the same wider portion of the table top. The problem here may be more eloquently explained as “Two roads diverged in a yellow wood[,] And sorry I could not travel both.” Robert Frost, The Road Not Taken, The Poetry of Robert Frost—The Collected Poems, 105, Henry Holt and Co. (1969). Considering the entire record before us in this case we credit Mr. Hatch’s testimony. The issue is not, as Patent Owner has framed it, whether “[o]ne of ordinary skill in the art would understand how the tenons and holes should be positioned on each of the table top portions.” Reply Opp. 7. The question is whether a person of ordinary skill in the art viewing the design for a table top in the proposed substitute claim as would an ordinary observer, understand whether or not the wider portion of the table top as Figures 1 and 6, holes. As Mr. Hatch persuasively explains, in the proposed substitute claim a majority of the drawings for the wider portion, i.e., Figures 1–6, omit the tenons added in Figure 8. Ex. 1011 ¶ 37 (Mr. Hatch testifying that “Figure 8 is the only amended figure that adds tenons/dowels.”) Indeed, Figures 1 and 6 not only fail to illustrate tenons, but actually are amended to include holes rather than tenons, as described in the Motion to Amend. See, e.g., Motion to Amend 6 (Patent Owner describing, “Figure 1: Removal of disclaimer of a total of four holes by amending the outline of the four holes from broken lines to solid lines.”).

“On the complete record in this proceeding, we determine that a designer of skill in the art considering the claim from either their own, or the perspective of an ordinary observer, would be uncertain whether the wider portion of the claimed table top depicted in Figures 1–8 includes tenons, or holes. It is reasonable that anyone observing two distinct ornamental designs for the same wider portion of the table top would be unclear as to the claimed ornamental design where holes are shown in one figure but tenons are shown in another figure illustrating the same wider portion of the table top. Observing as a whole, the figures illustrating the table top in the proposed substitute claim, the question remains, does the wider portion of the table top include tenons, or holes? See Maatita, 900 F.3d at 1376 (“Ultimately, a patent is indefinite for § 112 purposes whenever its claim, read in light of the visual disclosure (whether it be a single drawing or multiple drawings), ‘fail[s] to inform, with reasonable certainty, those skilled in the art about the scope of the invention.’”) (quoting Nautilus, Inc. v. Biosig Instruments, Inc., 572 U.S. 898 (2014)). proposed substitute claim fails to “inform those skilled in the art about the scope of the invention with reasonable certainty.” See Nautilus, 572 U.S. at 910. Thus, Petitioner has shown, by a preponderance of the evidence, that the proposed substitute claim is indefinite and we accordingly deny Patent Owner’s Noncontingent Motion to Amend.” slip op. at 29

“Federal Circuit recently explained that “a design patent is indefinite under § 112 if one skilled in the art, viewing the design as would an ordinary observer, would not understand the scope of the design with reasonable certainty based on the claim and visual disclosure.” In re Maatita, 900 F.3d 1369, 1377 (Fed. Cir. 2018). In Maatita, the Federal Circuit reversed the Board’s finding of indefiniteness of a design for a shoe bottom, i.e., a shoe sole, finding that Maatita’s two-dimensional drawing clearly demonstrates the perspective from which the shoe bottom should be viewed. A potential infringer is not left in doubt as to how to determine infringement. In this case, Maatita’s decision not to disclose all possible depth choices would not preclude an ordinary observer from understanding the claimed design, since the design is capable of being understood from the two-dimensional, plan- or planar-view perspective [] shown in the drawing. Id. at F.3d 1378–79. Different from Maatita, the issue in this proceeding is not whether an ordinary observer would sufficiently understand a three-dimensional ornamental design from a two-dimensional figure, but whether inconsistencies between figures of the proposed substitute claim render the scope of the claimed table top uncertain. See Maatita, 900 F.3d at 1376 (The Federal Circuit specifically distinguishing Maatita’s single two-dimensional drawing from indefiniteness issues raised by inconsistent drawings: “[h]ere, we are not dealing with inconsistencies in the drawings, or inconsistencies between the drawings and the verbal description, but” slip op. at 24

“Although the ’286 patent distinguishes “account data” from “transaction data” in the embodiment of Figure 11, the “transaction data” is submitted by the user to perform a series of banking transactions after manually entering a PIN code, whereas the “account data” is stored on the server, and the token information is accepted from the smart card’s embedded token, i.e., the output interface of the transaction card. See Ex. 1001, 10:12–18, 10:30–35, 10:40–42, 11:21–22, 11:65–12:4, 12:22–36. Thus, the claimed “transaction data” that is “accepted . . . from an output interface of a transaction card” and “accepted . . . from a transaction card at an input interface of the card reader,” as recited in independent claims 1 and 3, comprises data stored on and read from a card, such as an ID number, password, authentication information, or session information, that can be used to facilitate a transaction. Such claimed “transaction data” is distinct from the “transaction data” described in connection with the Figure 11 embodiment. We therefore do not limit the claimed “transaction data” and instead preliminarily construe that term as encompassing any data involved in a transaction, including account data. As described above, the claimed transaction data must come from the output interface of a transaction card.

“earlier applications, in particular Application No. 11/534,653 (“the ’653 application”), which issued as U.S. Patent No. 8,118,218 B2 (“the ’218 patent”). “‘It is elementary patent law that a patent application is entitled to the benefit of the filing date of an earlier filed application only if the disclosure of the earlier application provides support for the claims of the later application, as required by 35 U.S.C. § 112.’” PowerOasis, Inc. v. T- Mobile USA, Inc., 522 F.3d 1299, 1306 (Fed. Cir. 2008). The test for determining compliance with the written description requirement under § 112(a) is whether the original disclosure of the earlier-filed application reasonably would have conveyed to one with ordinary skill in the art that the inventor had possession of the claimed subject matter at the time of the earlier-filed application. Ariad Pharm., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc). It is well settled that “[e]ntitlement to a filing date does not extend to subject matter which is not disclosed but would be obvious over what is expressly disclosed.” Lockwood v. Am. Airlines, Inc., 107 F.3d 1565, 1571−72 (Fed. Cir. 1997). “It is not sufficient for purposes of the written description requirement of § 112 that the disclosure, when combined with the knowledge in the art, would lead one to speculate as to modifications that the inventor might have envisioned, but failed to disclose.” Id. We agree with Petitioner there does not appear to be support for limitation [1(j)] in the ’653 application. We find that the disclosure of the ’653 application—limited to general teachings of a smart card, an operating system, and a smart card manager—is insufficient to show possession of limitation [1(j)]. See Ex. 2001 (’218 patent), 4:47–56. As we explained above, “[e]ntitlement to a filing date does not extend to subject matter which is not disclosed but would be obvious over what is expressly disclosed.” Lockwood, 107 F.3d at 1571−72. The ’653 Application contains no disclosure of replacing applications, even if the disclosure might render such replacing obvious, it is not sufficient to show the possession required to establish entitlement to a priority date.

- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner
“We agree with Petitioner that, even if the applications were stored in “generic memory” as Patent Owner contends, Zhu provides adequate security and would not undermine Petitioner’s motivation to combine. See Intel, 61 F.4th at 1380 (“It’s not necessary to show that a combination is the best option, only that it be a suitable option.”). Indeed, Zhu addresses the problem Patent Owner contends it would cause in the combination.3 As Zhu 3 Patent Owner argues that Petitioner should be precluded from discussing Zhu’s encryption embodiment because it was not raised in the Petition. See Sur-Reply 6–7. We disagree. The claims do not recite anything about how the data should be stored. Thus, it is not surprising that the Petition did not address it. Patent Owner raised the teaching away argument regarding the security of the data. See PO Resp. 12–16. Petitioner relies on the exact same mapping, same motivation, and same arguments why Zhu accounted for certain limitations. See Reply 4–11. Petitioner’s Reply merely explained that Zhu did address the problem Patent Owner contended would “teach away” from the combination. Indeed, Patent Owner was aware of Zhu’s teachings and addressed them in their Patent Owner Response. The Federal recognizes, “[l]oading one of the smart card applications already resident on the smart card to another memory location on the mobile device can provide sufficient memory for the selected smart card application, but can also create a security problem.” Ex. 1006 (Zhu), 3:25–34. To address this problem, Zhu proposes encrypting these applications in generic memory which “reduces the possibility of unauthorized access to the information.” Id. at 3:59–61, 8:30–55, 9:28–33; Ex. 1033 (Smith Supp. Decl.) ¶¶ 5–6. Although acknowledging this disclosure, Patent Owner’s expert, Dr. Weaver, testifies that Zhu’s encryption is inadequate and that encryption would have certain drawbacks. See Ex. 2002 (Weaver Decl.) ¶ 69. We find this testimony, which directly contradicts the teachings of Zhu that encryption is an adequate solution, lacks sufficient support to be entitled to much weight. Dr. Weaver provides no citations to support his contention that a person of ordinary skill at the time of the invention would find encryption so inadequate or problematic as he now contends. Moreover, we find that Dr. Weaver’s testimony on cross examination provides an additional, independent basis to give this testimony little weight. On cross examination, Dr. Weaver contended that there was nothing uniquely inadequate about the particular encryption scheme disclosed in Zhu, but rather that his “opinion was more general, that encryption schemes known in the 2012 time frame were all breakable with computing power and time,” and thus, inadequate Circuit has explained that “the petitioner in an inter partes review proceeding may introduce new evidence after the petition stage if the evidence is a legitimate reply to evidence introduced by the patent owner.” Anacor Pharm., Inc. v. Iancu, 889 F.3d 1372, 1380–81 (Fed. Cir. 2018). That is the case here, so we find that Petitioner’s arguments and evidence regarding Zhu’s encryption are proper. for storing payment applications in a mobile device’s general memory. Ex. 1027 (Weaver Tr.), 26:11–23; see also id. at 23:3–8 (“[D]oes encryption ever provide a sufficiently high security to permit storing payment application on a mobile device’s general memory? A. No”); 24:15–25:23 (testifying all publicly known encryption schemes in 2012 were breakable). However, when confronted with the fact that the ’724 patent discloses storing payment application on general baseband memory using an encryption method that was breakable, id. at 26:24–29:7, Dr. Weaver testified that this encryption method was sufficient to allow storing payment applications in general baseband memory even though it was “not perfectly secure,” id. at 29:8–14. Dr. Weaver provides no explanation or rationale why the encryption method in the ’724 patent, which he admits suffers from the same drawbacks he identified with respect to Zhu, is sufficient, but other encryption methods would not be sufficient. In its Sur-reply, Patent Owner attempts to rehabilitate Dr. Weaver’s testimony with justifications and qualifications not found in his original testimony. Sur-Reply 7–8. Yet, Dr. Weaver’s testimony discussed above was clear and unequivocal. See Ex. 1027 (Weaver Tr.), 24:15–29:14. Patent Owner made no effort to redirect his testimony at his deposition, so it cannot now do so through mere attorney argument. We find the inconsistency between Dr. Weaver’s treatment of Zhu and his treatment of similar disclosure in the ’724 patent exposes the insufficient reasoning supporting his opinions regarding the adequacy of Zhu’s use of encryption in the combination. Accordingly, we give no weight to his testimony that a skilled artisan would not have combined Zhu with a Buhot/GPC system due to security concerns. In contrast, we find the testimony of Mr. Smith regarding the use of encryption and the tradeoffs with the benefits of adopting Zhu’s memory management technique, which he offers in his Supplemental Declaration, to be well-reasoned, consistent with the disclosure of Zhu and the ’724 patent4, and entitled to substantial weight. See Ex. 1033 (Smith Supp. Decl.) ¶¶ 4–15. As Petitioner recognizes, “‘[a] given course of action often has simultaneous advantages and disadvantages, and this does not necessarily obviate motivation to combine.’” Allied Erecting & Dismantling Co. v. Genesis Attachments, LLC, 825 F.3d 1373, 1381 (Fed. Cir. 2016). As Mr. Smith and Dr. Weaver testified, decryption without access to the security keys is an extremely computationally intensive and time-consuming process. Ex. 1033 (Smith Supp. Decl.) ¶¶ 6–8; Ex. 1027 (Weaver Tr.), 23:17–25:2; see also Ex. 10175, 132. Mr. Smith testifies that the benefits of using encryption would be sufficient to resolve the security concerns Patent Owner raises, and that any burden of generating a certificate would be outweighed by the benefits of using encryption and the memory advantages Zhu’s technique would offer.
