“See Section II.C.3.a.ii supra. Although Dr. Rubin calls Hayhurst’s security benefits “ancillary” (Ex. 2033 ¶¶ 108–109, quoted in PO Resp. 40), this does not align with Hayhurst (see Ex. 1007 ¶¶ 2, 7, 8, 21). For example, Hayhurst describes the security measures in the Technical Field section (id. ¶ 2) and the Summary of the Invention section (id. ¶¶ 7, 8). Hayhurst also discusses piracy deterrence in both the Summary of the Invention section (id. ¶ 8) and the invention’s detailed description (id. ¶ 21). Because Dr. Rubin does not give sufficient weight to Hayhurst’s discussion of piracy deterrence and security, we do not credit Dr. Rubin’s testimony on this issue. See Ex. 2033 ¶¶ 108–109. Thus, we agree with Petitioner that Hayhurst is reasonably pertinent to the network-security problem that the inventors were trying to solve. See Reply 5–6.” slip op. at 15

“Figure 6 of Rauhala has been annotated by Patent Owner to show that the parallel connection (outlined in red) including resistors R1, R2. R3 and switches ka, kb is outside the signal path (highlighted in yellow) through differential amplifier 61. Prelim. Resp. 38. Petitioner identifies R1, R2, R3 and switches ka and kb as the claimed variable impedance. See, e.g., Pet. 39–41. The Petition (and the supporting Baker Declaration) do not explain adequately how, under this interpretation by Petitioner and its expert, Rauhala meets the adjusting an impedance “in the signal path” limitation. See Prelim. Resp. 39–41. For the reasons given, therefore, even if we were to disagree with Patent Owner’s construction of “impedance,” we agree with Patent Owner that Petitioner fails to demonstrate sufficiently that Rauhala meets the limitation in claims 7 and 19 requiring “dynamically adjusting one or more of an impedance . . . in the [receiver] signal path.” For the reasons given, we determine that Petitioner has demonstrated a reasonable likelihood of prevailing on its challenge to claims 11 and 13 as anticipated by Rauhala.

“We disagree. Noting in the language of the claims requires that these method steps be performed by separate components, or that these method steps “provide two different channel indications at once” (Prelim. Resp. 38), only that they be performed as stated in the claim. In that respect, this case is distinguished from In re Robertson, where the Federal Circuit determined that the “third fastening means” required by the claims was not inherently disclosed by the prior art. Robertson, 169 F.3d at 745 (“The [prior art] patent does not expressly include a third fastening means for disposal of the diaper, as claim 76 requires.”). In further contrast to this case, Robertson addressed mechanical elements of a product (fasteners for disposable diaper), not steps in a process. More pertinent to our facts is the Federal Circuit’s decision in Microsoft Corporation v. Uniloc, 2017 LLC, No. 2021- 2039, 2022 WL 11531235 (Fed. Cir.

“Petitioner’s proposed level of ordinary skill does not differ materially from that presented by Mr. Welch. Both require a bachelor’s degree in many of the same fields and roughly one to two years of experience with USB protocols or USB product development. The arguments presented by Petitioner and Patent Owner do not indicate that the outcome of this case would change depending on the level of ordinary skill in the art. We, therefore, adopt Petitioner’s description, which we determine to be consistent with the level of skill reflected in the asserted prior art references. See Okajima v.

“Proof of conception must be by “corroborating evidence which shows that the inventor disclosed to others his ‘completed thought expressed in such clear terms as to enable those skilled in the art’ to make the invention.” Coleman v. Dines, 754 F.2d 353, 359 (Fed. Cir. 1985) (citing Field v. Knowles, 183 F.2d 593, 601 (CCPA 1950)); see also Mahurkar v. C.R. Bard, Inc., 79 F.3d 1572, 1577 (Fed. Cir. 1996) (corroboration requirement “arose out of a concern that inventors testifying in patent infringement cases would be tempted to remember facts favorable to their case by the lure of protecting their patent or defeating another’s patent”). Similarly, an inventor’s testimony alone is insufficient to establish an earlier reduction to practice. Medichem, S.A. v. Rolabo, S.L., 437 F.3d 1157, 1169–71 (Fed. Cir. 2006). Instead, a party seeking to prove an actual reduction to practice must proffer evidence corroborating that testimony. Id. at 1170. The sufficiency of corroboration is determined according to a “rule of reason.” Price v. Symsek, 988 F.2d 1187, 1195 (Fed. Cir. 1993). This, however, does not dispense with the requirement that some independent evidence provide corroboration. Coleman, 754 F.2d at 360. The requirement of “independent” corroboration requires evidence other than the inventor’s testimony. In re NTP, Inc., 654 F.3d 1279, 1291–92 (Fed. Cir. 2011). 3. Discussion We find that Patent Owner has not met its burden of establishing that Mr. Kuster conceived and reduced to practice his invention prior to the filing dates of Hsiao or He. By itself, Mr. Kuster’s testimony is insufficient to establish that he reduced his invention to practice prior to the November 23, 2010, filing date or Hsiao or the June 2, 2010, filing date of He. “Throughout the history of the determination of patent rights, oral testimony by an alleged inventor asserting priority over a patentee’s rights is regarded with skepticism, and as a result, such inventor testimony must be supported by some type of corroborating evidence.” Woodland Tr. v. Flowertree Nursery, Inc., 148 F.3d 1368, 1371 (Fed. Cir. 1998) (quoting Price, 988 F.2d at 1194).

“We do not agree with this argument. “The test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference; nor is it that the claimed invention must be expressly suggested in any one or all of the references. Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art.” MCM Portfolio LLC v. Hewlett-Packard Co., 812 F.3d 1284, 1294 (Fed. Cir. 2015) (quoting In re Keller, 642 F.2d 413, 425 (CCPA 1981)). Moreover, “[a] person of ordinary skill is also a person of ordinary creativity, not an automaton,” so the fact that it would take some creativity to carry out the combination does not defeat a finding of obviousness. KSR, 550 U.S. at 421; see also ClassCo, Inc. v. Apple, Inc., 838 F.3d 1214, 1219 (Fed. Cir. 2016) (“The rationale of KSR does not support [the] theory that a person of ordinary skill can only perform combinations of a puzzle element A with a perfectly fitting puzzle element B.”). We find there is support for making this combination of He and Cheng in the testimony of Dr. Baker that addition of a controller is “conventional” in USB flash drives. Baker Decl. ¶ 167. We find that for the reasons given by Dr. Baker, a person of ordinary skill would have added a controller to He. We determine that the combination of He and Cheng teaches each limitation of claim 11. We address Patent Owner’s argument that there are objective indicia of obviousness, infra.

- Obviousness (§103) › Objective indicia / secondary considerations › Long-felt need / failure of othersDecided for patent owner
“attorney argument, not evidence.” Pet. Reply 26. We agree. Patent Owner does not back up its argument with testimony or other credible evidence. To demonstrate long-felt need, a patentee must point to an “articulated identified problem and evidence of efforts to solve that problem” which were, before the invention, unsuccessful. Tex. Instruments v. Int’l Trade Comm’n, 988 F.2d 1165, 1178 (Fed. Cir. 1993). All Patent Owner proves, if anything, is that after the USB 3.0 specification issued, a number of companies rushed in to provide contacts that met the new standard. Patent Owner does not demonstrate that they failed where Mr. Kuster succeeded. In fact, there is no evidence that Mr. Kuster ever commercialized his invention.8 8 Victorinox never paid for the work Mr. Kuster did on the USB 3.0 memory device, and to Mr. Kuster’s knowledge, never marketed the product. Kuster Dep. 22:21–24:13. Patent Owner contends “Mr. Kuster’s invention filled the existing need for a durable yet slim USB flash drive compatible with USB 3.0 that was easy to manufacture.” PO Resp. 77. But instead of presenting independent evidence of failure of the others to solve known technical or manufacturing problems, Patent Owner relies on generalized statements concerning the need for USB 3.0 connectors and solutions by others that Patent Owner contends have not been successful. PO Resp. 74–77. We are not persuaded by Patent Owner’s argument that Mr. Kuster’s alleged invention filled a long-felt need where others failed.” slip op. at 29

“In the Decision on Institution, we adopted Petitioner’s proposed skill level, that is, that one of ordinary skill in the art would have a Bachelor’s degree or equivalent in electrical engineering, computer engineering, or similar field, and at least two years of experience in a relevant field such as telecommunications or multimedia communications. Inst. Dec. 20. We also agreed with Petitioner that one of ordinary skill would have some familiarity with the design and implementation of VoIP and multimedia networks. Id.

“As discussed above, we agree with Petitioner that Kirchhoff discloses the use of SSL, a protocol that uses data encryption (Ex. 1005, 8:47–49). We also agree with Petitioner that Krtolica discloses the use of HTTP protocols on port 80 (Ex. 1004, 6:23–24), and does so with a goal of maintaining high network security (id. at 1:7–10, 2:33–36). As Kirchhoff discloses, and Dr. Lavian’s testimony supports, one of ordinary skill in the art would have been aware that port 443, rather than port 80, would be used for secure web connections using SSL, which includes the use of encryption, and this would have resulted in enhanced network security. See Ex. 1005, 3:38–41; Ex. 1002 ¶¶ 52, 69, 108. As Dr. Lavian testifies, SSL/TLS was the most widely deployed security protocol in the world and the well-known use of SSL in HTTPS protocol enables secure web-based e-commerce. Ex. 1002 ¶¶ 69, 108; Ex. 1035 ¶ 8; Ex. 1006, 5. And, Krtolica has a stated goal to maintain network security. Ex. 1004, 1:7–10, 2:33–37. We find this evidence provides a sufficient rational underpinning in support of obviousness for combining the teachings of Krtolica and Kirchhoff. See KSR, 550 U.S. at 418. Owner’s arguments that use of encryption in SSL was optional and adding encryption would allegedly undermine network security. Nor do we find persuasive the argument that the Petitioner’s motivation to combine based on efficiency is insufficient, because Petitioner relies on another rationale for the combination of Krtolica and Kirchhoff, that is, enhanced network security, also discussed above. We additionally do not find persuasive Patent Owner’s arguments that combining Krtolica and Kirchhoff would render the system of Krtolica unsatisfactory for its intended purpose because, as Petitioner argues, this assertion is contradicted by the state of the art at the time. See Pet. Reply 9. As discussed above, Dr. Lavian explains that there were known systems having firewalls with SSL traversal at the time of the invention. Ex. 1002 ¶¶ 53, 59–65; Ex. 1035 ¶ 20; Ex. 1014. Moreover, the ’978 patent uses encryption with firewalls using a single-port protocol, and Patent Owner does not direct us to any disclosure in that patent that indicates that the use of encryption with a single-port protocol was inventive in that the system, or that encryption had to be done in a special manner. See Pet. Reply 3 (citing Ex. 1001, Fig. 3 (at 311, 341), Fig. 5 (503, 508)); see also Ex. 1001, 6:4–8. In a similar vein, Patent Owner argues that due to incompatibilities the combination of SSL with Krtolica would be unsuccessful, and we address this issue below.” slip op. at 30

“Where the prior art contains “apparently conflicting” teachings (i.e., where some references teach the combination and others teach away from it) each reference must be considered “for its power to suggest solutions to an artisan of ordinary skill . . . consider[ing] the degree to which one reference might accurately discredit another.” In re Young, 927 F.2d 588, 591 (Fed. Cir. 1991). In Hosner, AES encryption appears to have one of the higher processing speeds of the algorithms tested. See Ex. 1006, 23. Further, the ’978 patent itself supports the acceptable performance of AES encryption in single-port protocol, stating that “[a]ny method or algorithm of encryption may be used” with its invention “including, but not limited to 128-bit find Patent Owner’s argument on the use of AES to be persuasive. We have reviewed Petitioner’s explanations and supporting evidence as to how the combination of Kirchhoff and Krtolica teach the limitations of claims 4, 16, and 24, and we agree with and adopt Petitioner’s analysis.

“Appeals for the Federal Circuit, which vacated our Decision and remanded the matter to us. Samsung Elecs. Co. v. UUSI, LLC, 775 F. App’x 692 (Fed. Cir. 2019). As to the earlier instituted claims, the Court instructed that we should consider “whether Samsung has shown that there would have been a reasonable expectation of success in combining the teaching of Gerpheide with the teachings of Ingraham [I]/Caldwell to arrive at the claimed invention.” Id. at 697. The Court further instructed us to “consider the patentability of claims 37, 38, and 39” (id.) because, on April 24, 2018, the Supreme Court of the United States held that a decision to institute under 35 U.S.C. § 314 may not institute on fewer than all claims challenged in the petition.

- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for petitioner
“transition term[s]” should be considered in determining the meaning of a claim term, but asserts without further support that the presence of a semicolon after “supply voltage” and the use of the transition term “wherein” do not compel the preliminary construction. Id. As we addressed in denying Petitioner’s Request for Rehearing, claim 37 employs the open-ended transition term “comprising” followed by a colon to indicate that a list elements follows, and employs semicolons to separate the elements of that list. Paper 17, 5. The first element of the list, element 37a, describes an oscillator and includes the supply voltage limitation preceded by a comma and the transition term “wherein.” Id. Element 37a then ends with a semicolon and the claim proceeds to element 37b, which recites a microcontroller. Id. Petitioner thus nominally acknowledges consideration of punctuation, but advances a construction that asks us to disregard punctuation affirmatively recited in the claim. To do so would be “inconsistent with the punctuation [patentee] chose for this claim.” In re Pelz, 379 F. App’x 975, 978 (Fed. Cir. 2010). Likewise, as to Petitioner’s assertion that we read an additional limitation into the claim (Pet. Br. 10), we observe that, if the claim is limited to a particular exemplary embodiment, such a limitation results from the claim being drafted to cover only that embodiment. While we confirmed in the Decision on Institution that the use of the term supply voltage is consistent with its use in the Specification (Dec. on Inst. 9), the limitation of the claim to the oscillator is based on the language of the claim, not on definition or disavowal. Therefore, even accepting, for the sake of argument, that there is no disavowal or definition in the Specification of “supply voltage,” the term refers in independent claim 37 to supply voltage of the oscillator.” slip op. at 18

“We disagree with Patent Owner’s arguments because they are not responsive to the combination of teachings at issue in the references before us. Patent Owner focuses on particular features of Gerpheide that it alleges either “would not work . . . in the proposed Caldwell-Ingraham system” or “can only work” in the presence of a component Patent Owner argues that “neither Ingraham nor Caldwell uses.” PO Br. 1–2, 12–13. These arguments are based on a mistaken premise that one or more components or physical configurations of Gerpheide must be incorporated into the combination of Ingraham I and Caldwell in order to show a reasonable likelihood of success. Under the Federal Circuit’s construction of the “selectively providing” limitation, the combination of Ingraham I, Caldwell, and Gerpheide need not incorporate the specific features of Gerpheide identified by Patent Owner. Petitioner asserts, supported by evidence from Dr. Subramanian, that the Ingraham I-Caldwell combination would have been modified based on Gerpheide “to provide features that adjust[] the oscillator signal frequency provided to the input portions 13 to negate the effect of interference on the input portions 13 and touch sensing circuits.” Pet. 26–27. This modification would not require any of the particular components or configurations of Gerpheide highlighted by Patent Owner. Thus, even if one or more of Patent Owner’s arguments as to the infeasibility of incorporating particular aspects of Gerpheide were correct, Patent Owner’s arguments do not address Gerpheide’s particular teaching of adjusting oscillator signal frequency to negate the effect of interference, and therefore, Patent Owner’s arguments are not responsive to the proposed combination and evidence relied upon by Petitioner. In view of the above, we find that Petitioner has shown that the skilled artisan would have combined Gerpheide with Ingraham/Caldwell as proposed with a reasonable expectation of success in achieving the claimed subject matter.” slip op. at 26
