“C. Level of Ordinary Skill in the Art Factors pertinent to determining the level of ordinary skill in the art include (1) the educational level of the inventor; (2) the type of problems encountered in the art; (3) prior-art solutions to those problems; (4) the rapidity with which innovations are made; (5) the sophistication of the technology; and (6) the educational level of workers active in the field. Envtl. Designs, Ltd. v. Union Oil Co., 713 F.2d 693, 696–97 (Fed. Cir. 1983). Not all factors may exist in every case, and one or more of these or other factors may predominate in a particular case. Id. These factors are not exhaustive, but merely a guide to determining the level of ordinary skill in the art. Daiichi Sankyo Co. v. Apotex, Inc., 501 F.3d 1254, 1256 (Fed. Cir. 2007). Moreover, the prior art itself may reflect an appropriate skill level. Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). Petitioner asserts that a person of ordinary skill in the art at the ’336 patent’s effective filing date would have had “a bachelor’s degree in mechanical engineering, electrical engineering, optics, or physics with at least three years of experience working in the design of LED lights or lighting fixtures; a master’s degree in one of the above disciplines with at least two years of experience; or equivalent experience.” Pet. 14 (citing Ex. 1004 ¶¶ 26–29). Dr. Eden’s testimony supports Petitioner’s assertion. See Ex. 1004 ¶¶ 27–28. Patent Owner “adopts for purposes of this proceeding only” Petitioner’s description of an ordinarily skilled artisan.

“Alleged Objective Indicia of Nonobviousness (i) General Principles Before reaching a conclusion about obviousness, we consider evidence concerning objective indicia of nonobviousness. See Apple, 839 F.3d at 1048. For such evidence to have substantial weight, “its proponent must establish a nexus between the evidence and the merits of the claimed invention.” ClassCo, Inc. v. Apple, Inc., 838 F.3d 1214, 1220 (Fed. Cir. 2016); see Ancora Techs., Inc. v. Roku, Inc., 140 F.4th 1351, 1361 (Fed. Cir. 2025) (noting that the Board did not err by requiring “a nexus to the challenged claims as opposed to the patent as a whole”). “[T]here is no nexus unless the evidence presented is ‘reasonably commensurate with the scope of the claims.’” ClassCo, 838 F.3d at 1220 (quoting Rambus Inc. v. Rea, 731 F.3d 1248, 1257 (Fed. Cir. 2013)). The patentee “bears the burden of showing that a nexus exists.” WMS Gaming, Inc. v. Int’l Game Tech., 184 F.3d 1339, 1359 (Fed. Cir. 1999). A rebuttable presumption of nexus arises “when the patentee shows that the asserted objective evidence is tied to a specific product and that product ‘embodies the claimed features, and is coextensive with them.’” Fox Factory, Inc. v. SRAM, LLC, 944 F.3d 1366, 1373 (Fed. Cir. 2019) (quoting Polaris Indus., Inc. v. Arctic Cat, Inc., 882 F.3d 1056, 1072 (Fed. Cir. 2018)). Whether a rebuttable presumption of nexus arises “turns on the nature of the claims and the specific facts.” Teva Pharms. Int’l GmbH v. Eli Lilly & Co., 8 F.4th 1349, 1362 (Fed. Cir. 2021). The presumption analysis should consider the unclaimed features in the product tied to the objective evidence to assess their significance and impact on the correspondence between the patented invention and the product. Quanergy Sys., Inc. v. Velodyne Lidar USA, Inc., 24 F.4th 1406, 1418 (Fed. Cir. 2022). When, “for example, the patented invention is only a small component of the product tied to the objective evidence, there is no presumption of nexus.” Henny Penny Corp. v.

“We find Patent Owner’s argument that a link is a physical connection (PO Resp. 19; PO Sur-reply 2) unavailing. In particular, claims 1 and 6 do not recite any requirement that a “link” is “physical.” Further, as Petitioner points out, there is no support in the ’775 patent for “defining ‘link’ as only a physical connection,” and Patent Owner does not point to any disclosure in the ’775 patent for such support. Pet. Reply 5. Although we agree with Patent Owner that a link can connect the interfaces of routers wherein routers are “physical devices” (PO Sur-reply 2), claims 1 and 6 do not require that the link physically connects the routers. That is, the claims merely require a pseudo-wire to comprise a link set up between routers to connect the routers. We agree with Petitioner that pseudo-wires comprising the connection links “can connect to any interface, ‘whether it is a physical, logical, or virtual interface.’” Pet. Reply 5 (citing Ex. 1043, 10; Ex. 1010, 3; Ex. 1042 ¶ 7). In fact, during oral argument, Patent Owner acknowledges that “[a] link, . . . , is not limited to a physical connection.” See Tr. 30:6–7.” slip op. at 10
- Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Term construed board ownDecided for patent owner
“We find unavailing Patent Owner’s arguments that a pseudo-wire (“a type of emulated connection”) cannot be the same as a link (“a type of physical connection between router interface”). PO Resp. 20. In particular, claim 1 does not recite any requirement that a link be a physical connection, and thus, does not require that a link differs from the emulated connection of a pseudo-wire. As discussed above, during oral argument, Patent Owner acknowledges that a link is not limited to a physical connection. See Tr. 30:6–7. The ’775 patent itself provides no definition for “pseudo-wire” to support Patent’s Owner’s construction, and Patent Owner does not point to any disclosure in the ’775 patent for such support. As Petitioner points out, the ’775 patent instead supports a construction of “pseudo-wire” as comprising multiple links, wherein “[t]he first and second links constitute a first pseudo-wire pw1” and the second “pseudo-wire ps2 consists of the first link L1 and a second link L3.” Pet. Reply 7 (emphasis omitted) (citing Ex. 1001, 6:29–43). We find availing Petitioner’s argument that, even if links were “physical connections” as Patent Owner asserts, “then the pseudo-wire consists of . . . two physical connections,” no different from a link, contrary to Patent Owner’s assertion. Id. (citing Ex. 1042 ¶ 10). Although Patent Owner argues that the POSITA has always considered a pseudo-wire as a point-to-point link set up between input and output routers (PO Resp. 5–6), claims 1 and 6 do not recite that a pseudo-wire comprises a point-to-point link set up, and there is no support in the ’775 patent for specifically defining “pseudo-wire” as and limiting the term to a point-to-point link set up.” slip op. at 12
- Expert testimonyPetitioner expert creditedDecided for petitioner
“Dr. Bhattacharjee testified in support of Petitioner’s position that “[a] POSITA would have understood that the ordinary meaning of ‘link,’ . . . includes both physical and virtual connections, particularly in the context of pseudo-wires.” Ex. 1042 ¶ 7. We find availing Dr. Bhattacharjee’s testimony, which is supported by evidence. See id. (citing Ex. 1043, 10; Ex. 1010, 3 (disclosing that pseudo-wires encapsulate “data arriving at the PE-bound port (logical or physical)”), 4 (disclosing that the attachment circuit over which the pseudo-wire is established can be a “physical or virtual circuit”)). For the reasons discussed above, we conclude that a “link” is not required to be a physical connection. Instead, we determine that a “link” connects the interfaces of first and second routers, whether they are physical, logical, or virtual interfaces.” slip op. at 11

“Here, as Petitioner points out, “the Challenged Claims . . . do not recite ‘means for’ or ‘step for.’” Pet. Reply 1. As the Federal Circuit stated, when a disputed claim limitation does not employ “means for” language, the presumption is that each of the terms conveys sufficiently definite structure or act and, thus, is not subject to § 112(f). See Dyfan, 28 F.4th at 1367. Based on the record before us, this presumption that each of the terms is not subject to § 112(f) is not overcome. Although Patent Owner argues that “to claim a means for performing a specific computer-implemented function and then to disclose only a general purpose computer as the structure designed to perform that function, amounts to pure functional claiming” (PO Sur-reply 5), the question here is whether “means for” analysis under § 112(f) applies at all. That is, as Patent Owner acknowledges, we must determine first whether the claim is even claiming a “means for” performing a function, “and then” determine whether the structure designed to perform that function is a general purpose computer. Id. As set forth in MPEP § 2181, the three-step analysis in determining whether § 112(f) applies begins with determining whether a claim limitation uses 1) the term “means” or “step” or 2) a nonce term used as a substitute for “means” that is a generic placeholder. See MPEP § 2181(I). We agree with Petitioner’s contentions during oral argument that Patent Owner’s arguments appear to be “based on adding a third general purpose computer structure category that triggers MPF treatment not supported by any case law.” Tr. 32:10–12. Accordingly, although Patent Owner argues that “claim 1 invokes § 112[(f)]” (PO Resp. 8, 18), and then provides extensive arguments with supporting testimony from Dr. Jakobsson as to the algorithm defining “local, secured information” (id. at 10–20 (citing Ex. 2016 ¶¶ 18, 38–51, 53–55)) and “algorithm of control logic 250” (id. at 21–25 (citing Ex. 2016 ¶¶ 37, 58)), the presumption that each of the terms is not subject to § 112(f) is not overcome; thus, we decline Patent Owner’s invitation to proceed to determining the corresponding algorithm.” slip op. at 18

In particular, Petitioner contends that a POSITA would have been motivated to integrate a PDK and RDC into a hybrid device by recognizing that Giobbi-157 and Giobbi-139 are “directed to similar operations,” “describe similar structures for performing those operations,” and have techniques that “are compatible with each other,” wherein combining the techniques “would have worked in the same manner already described in the references.” Id. at 21–22. Petitioner then contends that “Dua further corroborates the teachings of the Giobbi references and provides implementation details for integrating an RDC and PDK into the same device,” wherein “a POSITA would have been motivated to combine the teachings of the Giobbi references and Dua” because, at least “these references are all in the same field of endeavor.” Id. at 23–24.

“Owner’s arguments that claim 1 invokes 35 U.S.C. § 112(f), with which, as discussed above, we do not agree. In particular, although Patent Owner argues that Giobbi ’157 does not teach or describe unlocking information from a service block in exchange for an access key “as required in the challenged claims” (PO Resp. 30), and thus fails to disclose the “enabling” function as required by the claim, claim 1 merely requires that one or more of the integrated RDC and integrated PDK enables one or more of an application, a function, and a service. In Giobbi ’157, when the PDK enters a proximity zone of the RDC, the RDC requests profile data stored within the PDK for authentication, and if the profile data received from the PDK is valid, the RDC “completes the transaction.” See Ex. 1005 ¶¶ 59–63. We find availing Petitioner’s reliance of Giobbi ’157’s completion of a transaction by the PDK and the RDC to gain access as teaching “enabling access to secure physical or digital assets,” i.e., “enabling one or more of an application, a function, and service” by at least one of a PDK and RDC.

Based on the complete record presented, we determine that Petitioner has persuasively shown that the proposed combination of Giobbi ’157, Giobbi ’139, and Dua teaches “one or more of the integrated RDC and integrated PDK enabling one or more of an application, a function, and a service on one or more of the hybrid device and a device associated with the external RDC,” as recited in claim 1.” slip op. at 45

“Owner’s arguments that claim 1 invokes 35 U.S.C. § 112(f), with which, as discussed above, we do not agree. In particular, although Patent Owner argues that Giobbi ’157 does not teach or describe unlocking information from a service block in exchange for an access key “as required in the challenged claims” (PO Resp. 30), and thus fails to disclose the “enabling” function as required by the claim, claim 1 merely requires that one or more of the integrated RDC and integrated PDK enables one or more of an application, a function, and a service. In Giobbi ’157, when the PDK enters a proximity zone of the RDC, the RDC requests profile data stored within the PDK for authentication, and if the profile data received from the PDK is valid, the RDC “completes the transaction.” See Ex. 1005 ¶¶ 59–63. We find availing Petitioner’s reliance of Giobbi ’157’s completion of a transaction by the PDK and the RDC to gain access as teaching “enabling access to secure physical or digital assets,” i.e., “enabling one or more of an application, a function, and service” by at least one of a PDK and RDC. See Pet. 37. Based on the complete record presented, we determine that Petitioner has persuasively shown that the proposed combination of Giobbi ’157, Giobbi ’139, and Dua teaches “one or more of the integrated RDC and integrated PDK enabling one or more of an application, a function, and a service on one or more of the hybrid device and a device associated with the external RDC,” as recited in claim 1.” slip op. at 45

“recite ‘means for’ or ‘step for.’” Pet. Reply 1. As the Federal Circuit stated, when a disputed claim limitation does not employ “means for” language, the presumption is that each of the terms conveys sufficiently definite structure or act and, thus, is not subject to § 112(f). See Dyfan, 28 F.4th at 1367. Based on the record before us, this presumption that each of the terms is not subject to § 112(f) is not overcome. Although Patent Owner argues that “to claim a means for performing a specific computer-implemented function[] and then to disclose only a general purpose computer as the structure designed to perform that function amounts to pure functional claiming” (PO Sur-reply 3), the question here is whether “means for” analysis under 112(f) applies at all. As Petitioner explained during oral arguments, the parties agree that “the law has been consistent and clear” that “the proper framework for an MPF [means-plus-function] construction analysis consists of two steps,” with the first being “determin[ing] whether the limitation is or is not an MPF limitation,” and “[o]nly if the limitation is determined or deemed to be an MPF limitation . . . do you then proceed to step 2 . . . where you analyze the specification of the patent to identify structure corresponding to the MPF limitation.” Tr. 17:22– 18:5. That is, as Petitioner pointed out, “all of the case law identified by [Patent Owner] limits this general purpose computer analysis to the second step of the MPF analysis.” Id. at 19:5–7. Thus, although Patent Owner argues that “[s]ince claim 1 invokes § 112[(f)]” (PO Resp. 9, 22), and then provides extensive arguments with supporting testimony from Dr. Jakobsson as to the “algorithm defining ‘local, secured information’” (id. at 9–19 (citing Ex. 2014 ¶¶ 18, 36–37, 40–54)) and “algorithm of control logic 250” (id. at 19–22 (citing Ex. 2014 ¶¶ 55–57)), the presumption that each of the terms is not subject to § 112(f) is not overcome; thus, we decline Patent Owner’s invitation to proceed to determining the corresponding algorithm.” slip op. at 16

“would have found it obvious to combine the teachings of Giobbi ’157 and Giobbi ’139 (Pet. 12–22), and furthermore combine the teachings of Dua to the teachings of Giobbi ’157 and Giobbi ’139 (id. at 23–25), citing Dr. Traynor’s testimony for support. In particular, Petitioner contends that a POSITA would have been motivated to integrate a PDK and RDC into a hybrid device by recognizing that Giobbi-157 and Giobbi-139 are “directed to similar operations,” “describe similar structures for performing those operations,” and have techniques that “are compatible with each other,” wherein combining the techniques “would have worked in the same manner already described in the references.” Id. at 20–21. Petitioner then contends that “Dua further corroborates the teachings of the Giobbi references and provides implementation details for integrating an RDC and PDK into the same device,” wherein “a POSITA would have been motivated to combine the teachings of the Giobbi references and Dua” because, at least “these references are all in the same field of endeavor.” Id. at 23. Patent Owner does not address separately Petitioner’s explanations and supporting evidence regarding the remaining limitations in claim 1, or regarding the proffered reasoning to combine the references. See generally PO Resp. We have reviewed Petitioner’s explanations and supporting evidence regarding these limitations, as well as Petitioner’s proffered reasoning to combine the references, and we agree with and adopt them as our own. Pet. 29–33. Because Patent Owner does not separately address these limitations or Petitioner’s proffered reasoning for combining the references, the Petitioner’s positions regarding these limitations of independent claim 1 and the combination of references stand unopposed as a part of this trial. Based on the complete record presented, we determine that Petitioner has persuasively shown that the proposed combination of Giobbi ’157, Giobbi ’139, and Dua teaches the remaining limitations of claim 1, and that a person of ordinary skill in the art would have combined these references.” slip op. at 39

“Giobbi ’157 teaches, for example, an RDC requesting profile data stored within the external PDK for authentication, wherein if the profile data received from the external PDK is valid, the RDC completes the transaction, which includes enabling access to secure physical or digital assets.

For example, Petitioner contends that Giobbi ’139 “discloses that RDCs operate on battery power (such that the device including an RDC contains ‘a battery’.)” Id. at 26 (citing Ex. 1006 ¶ 89). In addition, Petitioner contends that “Dua discloses that its devices include an ‘internal battery 103.’” Id. at 27 (citing Ex. 1007 12:36–45, 13:49–60, Figs. 1, 5–6; Ex. 1003 ¶ 58).

“Because the determination of whether the claims invoke § 112(f) comes down to “whether the words of the claim are understood by persons of ordinary skill in the art to have a sufficiently definite meaning as the name for structure” (Williamson, 792 F.3d at 1348), we find Dr. Traynor’s testimony that claim 1 recites sufficiently definite structure persuasive. Ex. 1032. As the Federal Circuit advised in Williamson, declarations and/or testimony of expert witnesses can play a large role in this determination. Williamson, 792 F.3d at 1348. Similarly, in Dyfan, the Federal Circuit found the district court ignored key evidence – unrebutted deposition testimony regarding how a POSITA would have understood claim terms at issue. Dyfan, 28 F.4th at 1367. In particular, the Federal Circuit in Dyfan found to be “key evidence” the expert’s explanation that the terms, themselves, connote structure, wherein, in combination with the recitation of the code or application’s operation would have connoted structure to a POSITA. Id. In this proceeding, we find persuasive Dr. Traynor’s testimony that a POSITA would have understood the terms “local, secured information stored by the integrated, secure memory,” and “wireless communication interface communicating wirelessly with the at least one external device within the proximity zone,” to have “sufficient definite structure, such that a § 112, ¶ 6 interpretation is improper.” Ex. 1032 ¶ 4. In particular, we find persuasive Dr. Traynor’s testimony that the term “memory” alone has definite structure, and, for example, “is defined as the ‘capacity of a computer or integrated computer system for short and medium-term retention of digital data’ and speaks to a broad class of structures used to retain data for various purposes.” Id. at 5 (citing Ex. 1020, 5). According to Dr. Traynor, “not only does memory connote structure, but a POSITA would have recognized that memory can participate in ‘enabl[ing] one or more of an application, a function, and a service’ by simply storing information . . . necessary to access or otherwise invoke that application.” Id. at 6 (first alteration in original). Dr. Traynor’s testimony is consistent with the Specification of the ’960 patent, which describes a microchip that stores information in memory and responds through an antenna when probed. See Ex. 1001, 2:3–29. Similarly, we also find persuasive Dr. Traynor’s testimony that a “wireless communication interface communicating wirelessly with the at least one external device within the proximity zone” also has sufficiently definite structure for performing the function of “enabling one or more of an application, a function and a service.” Ex. 1032, 8. In particular, we find persuasive Dr. Traynor’s testimony that “a POSITA would have understood that an ‘integrated wireless communication interface’ speaks to a class of structures used to connect to wireless networks.” Id. According to Dr. Traynor, “[a] POSITA also would have readily recognized that a ‘wireless communication interface’ is often used to ‘enable one or more of an application, a function, and a service’ by enabling wireless communication of information . . . necessary to access or otherwise invoke that application, function, or service.” Id. at 10. Dr. Traynor cites to various technical dictionaries to persuasively support his testimony. See Ex. 1021 (WILEY ELECTRICAL AND ELECTRONICS ENGINEERING DICTIONARY), 11–12; Ex. 1023 (NEWTON’S TELECOM DICTIONARY), 5; Ex. 1024 (THE AUTHORITATIVE DICTIONARY OF IEEE STANDARDS TERMS), 5–7; Ex. 1025 (MICROSOFT COMPUTER DICTIONARY), 3–4.
