“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)).

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.

“Patent Owner has applied Petitioner’s definition of the level of skill of a person of ordinary skill in the art. PO Resp. 13. We apply Petitioner’s undisputed level of skill in the art with the exception of the phrase “at least” which injects potential ambiguity into the level of skill, because Petitioner’s proposed level of skill appears consistent with the problems addressed in the ’512 patent and the prior art.” slip op. at 11

- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner
“For the following reasons, based on the evidence and arguments presented by Petitioner, we are persuaded that Petitioner establishes that an ordinarily skilled artisan would have been motivated to combine Kesanupalli and Challener with a reasonable expectation of success. Pet. 23–24; Ex. 1003 ¶¶ 48–51, 83. First, Patent Owner’s reliance on what Mr. Ramesh Kesanupalli, the individual, allegedly chose not to include in the disclosure of the Kesanupalli patent reference is unavailing. The question of obviousness is determined from the perspective of a hypothetical person of ordinary skill in the art not an actual person who may or may not have been a person of ordinary skill in the art. Ramesh Kesanupalli is one of five named co-inventors on Kesanupalli. Ex. 1006, code (75). 7 Patent Owner’s argument, in essence, is an improper request to limit the Kesanupalli reference to just the explicit problems addressed, solutions proposed, and goals achieved by the Kesanupalli reference. However, “[t]he use of patents as references is not limited to what the patentees describe as their own inventions or to the problems with which they are concerned. They are part of the literature of the art, relevant for all they contain.” In re Heck, 699 F.2d 1331, 1333 (Fed. Cir. 1983) (citing In re Lemelson, 397 F.2d 1006, 1009 (CCPA 1968)). We have reviewed all of the cases cited by Patent Owner regarding the determination of obviousness. None of them is at odds with the principle stated in Heck.” slip op. at 28

“Ex. 1001, 4:46–50. This passage indicates that the interconnect can be a network on a chip and the network on a chip can include wires and buses. That does not necessarily mean that the interconnect can be just wires or buses; rather, it discloses that the interconnect can include wires and buses. In context, the disclosure regarding wires and buses does not support construing the corresponding structure broadly enough to encompass just wires and buses. The networks that constitute the corresponding structure, however, could include networks with wires and buses. Therefore, we agree with Patent Owner that the corresponding structure for the interconnect means should not include a mere bus, switch, and point-to-point wire and instead find that the corresponding structure under 35 U.S.C. § 112 ¶ 6 is a network, which the ’052 patent describes as a multi-hop interconnection between modules separated by one or more network nodes. See Ex. 1001, 2:33–37. Because this structure corresponds to the construction of “interconnect means” proposed by Patent Owner and adopted by the district courts in the TI and Qualcomm litigations (see supra Section III.C.3.b), and we do not rely in our analysis below on a recourse to “equivalents thereto” as permitted by § 112 ¶ 6, we note that our ultimate conclusions on the unpatentability of the challenged claims would be the same if § 112 ¶ 6 did not apply. iii. Conclusion For the reasons stated above, we construe “interconnect means” to cover the structure described in the Specification corresponding to the specified functions of “coupling said plurality of processing modules (M, S)” in the context of claim 6 and “coupling said plurality of processing modules (M, S)” and “enabling a connection-based communication having a set of connection properties” in the context of claims 1 and 7—i.e., a “multi-hop interconnection between modules separated by one or more network nodes”—and equivalents thereof.” slip op. at 28
