Patent Owner does not dispute and applies Petitioner’s proposed level of skill. PO Resp. 6. We find that Petitioner’s proposal is reasonable and consistent with the ’832 patent specification and the prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

      “Thomason are in the same field of endeavor. Thomason describes a camera and method for correctly orientating pictures from the camera. See, e.g., Ex. 1004 ¶¶ 1, 2 29–40, Figs. 3a–3b. In particular, Thomason is interested in rotating and cropping images to reduce the effect of poor orientation. Pet. 9 (citing Ex. 1004 ¶¶ 2, 34, 36). Pacurariu likewise describes aligning and resizing/cropping of a captured image to correct poor orientation. See, e.g., Ex. 1005 ¶¶ 1, 3, 45–56, Figs. 5A–5C. The preponderance of the evidence also supports that a person having ordinary skill in the art would have had reason to combine the Pacurariu’s teachings with Thomason to predictably improve Thomason. Thomason teaches correct rotation of video data and makes use of rotation sensor to correct rotated images. Pet. 19–21 (citing, e.g., Ex. 1004 ¶¶ 4, 27, 29, 35; Ex. 1002 ¶¶ 76–77). Pacurariu similarly uses sensors and measures tilt angle of the camera. Id at 21–22 (citing, e.g., Ex. 1005 ¶¶ 51–52, Fig. 6; Ex. 1002 ¶ 78). Pacurariu further teaches that its tilt data angle can be stored for each “video frame.” Id. at 22 (citing Ex. 1005 ¶ 52). Petitioner, with support from credible testimony of Dr. Katsaggelos, explains how the teachings of Thomason and Pacurariu could be successfully combined. Id. at 23 (citing, for example, Ex. 1002 ¶ 81). A person of ordinary skill in the art could have known that Thomason’s system could be improved by saving rotation data for each video frame and correcting images on a frame-by-frame basis. Id. at 23–24. The testimony of Dr. Katsaggelos is credible in this regard. Ex. 1002 ¶¶ 80–81. Petitioner and Dr. Katsaggelos explain the references’ teachings and, based on these teachings, assert that a person having skill in the art would have had reason to combine with reasonable expectation of success based on those teachings. Reason to combine may properly come from the references themselves. KSR Int’l Co., 550 U.S. at 418 (explaining reason to combine may come from “interrelated teachings of multiple patents”). Based on the evidence presented, Petitioner establishes by a preponderance of the evidence that a person having ordinary skill in the art would have had reason to combine the teachings of Thomason and Pacurariu with a reasonable expectation of success. Ex. 1002 ¶¶ 76–81, 89–92; Ex. 1004 ¶¶ 4, 8–9, 27, 29, 35; Ex. 1005 ¶¶ 26, 41, 46, 51–52, 55–57, Figs. 6, 7.” slip op. at 27

    • Skill levelOther

      “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. Frymaster LLC, 938 F.3d 1324, 1333 (Fed. Cir. 2019). Absent a presumption of nexus, the patentee may prove nexus by” slip op. at 76

      “This disclosure is inconsistent with any suggestion that the Fangman system, when routing a telephone call to its destination, identifies the private IP address of the destination telephone by determining the port range to which the port number of the destination telephone belongs. When Fangman describes the NAPPT process, it does not indicate that port ranges are used, but rather repeatedly states that port numbers are used: The [service gateway] receives a data packet from the IP device, including a public destination IP address . . . a destination port number . . . and source information, NAPPTs the data packet, using the [public destination IP address] and the [destination port number] to identify the [IP telephone] . . . . Ex. 1024, code (57). Performing NAPPT on the data packet received from the destination may include using the public destination IP address and the destination port number to uniquely identify the IP telephone, and changing the public destination IP address to a private source IP address of the IP telephone while leaving the destination port number unchanged.

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for petitioner

      “require “selecting an entity pair from” all of the entity pairs of “said plurality of transport entities.” Contrary to Patent Owner’s arguments addressing the claim language, the plain language of claim 1 does not require the selection to be from all of the entity pairs of the plurality of transport entities for which an overall cost has been determined. The plain language of claim 1 also does not preclude the selection to be from a subset of the entity pairs of the plurality of transport entities for which an overall cost has been determined. Rather, dependent claim 9, through its dependence on claims 1 and 4, explicitly allows for the selection to be from a subset of the entity pairs of the plurality of transport entities. Patent Owner’s arguments advocate for the importation of limitations from the ’821 Patent Specification into the claim––namely the disclosure that all entity pairs of transport entities examined in step 220 of Figure 2 are input to the entity pair selection step 230. See PO Sur-reply 4. It is well settled that it is improper to read an extraneous limitation into a claim from the specification. See e.g., Commark Comm’s Inc. v. Harris Corp., 156 F.2d 1182, 1186 (Fed. Cir. 1998); E.I. du Pont de Nemours & Co. v. Phillips Petroleum Co., 849 F.2d 1430, 1433 (Fed. Cir. 1988). An extraneous limitation is “a limitation read into a claim from the specification wholly apart from any need to interpret what the patentee meant by particular words or phrases in the claim.” E.I. du Pont de Nemours, 849 F.2d at 1433. Accordingly, we construe “selecting an entity pair from said plurality of transport entities based at least upon said overall cost” according to its plain meaning, the scope of which includes selecting an entity pair from all or a subset of the entity pairs of the plurality of transport entities for which an overall cost has been determined.” slip op. at 11

      “Based on the entire record and after having considered Petitioner’s citations to Doshi, Guichard, and Dr. Houh’s testimony (Ex. 1003) as well as Patent Owner’s citations to Doshi, Guichard and Mr. Gomez’s testimony, we are persuaded Petitioner sets forth sufficient articulated reasoning with rational underpinning to support the conclusion that it would have been obvious to one of ordinary skill in the art to combine the teachings of Doshi with Guichard’s teachings of reoptimization of a LSP path triggered by an network change. See Pet. 20–22, 40–45; KSR, 550 U.S. at 418. Petitioner asserts that “[t]he results of the combination would have been predictable and there would have been a reasonable expectation of success since Doshi and Guichard both address the same technology.” Pet. 22 (citing Ex. 1003 ¶¶ 63–65). According to Petitioner, “a POSITA would have had a reasonable expectation of success in reoptimizing Doshi’s LSP pair selection because Guichard provides significant implementation details, including when to trigger reoptimization evaluations and how to ‘avoid network instabilities.’” Pet. 22–23 (citing Ex. 1003 ¶¶ 63–65; Ex. 1006, 5). Petitioner asserts that a reasonable expectation of success is evidenced by other skilled artisans that reoptimized similar systems.

According to Petitioner, “since Doshi is already ‘monitoring and updating . . . network topology’ . . . event-based reoptimization evaluation per Guichard, would be directly applicable.” Id.

      “The parties’ articulations of the level of ordinary skill in the art are similar, and we adopt parts of each party’s description of a POSITA’s education and experience. We agree with Patent Owner that computer engineering is a relevant field of study. PO Resp. 3. Our finding is supported by the ’700 Patent, which describes systems, devices, methods, and software for forward error correction for a flash memory system, which may be integrated with a computer, server, or other computing device. Ex. 1001, 3:23–30. We adopt Patent Owner’s proposal regarding the length of a POSITA’s practical experience—two years—rather than four years, as proposed by Petitioner. Neither Petitioner nor Dr. Dolecek assert that two years of practical experience would have been insufficient to acquire POSITA’s experience would have been limited to “hardware implementation.” PO Resp. 3. Our finding is supported by the ’700 Patent, which states that “embodiments may be implemented by hardware, software, firmware, middleware, microcode, hardware description languages, or any combination thereof.” Ex. 1001, 10:26–28. Petitioner’s assertion that a POSITA needs to have experience in “error correction coding (‘ECC’) systems (which include forward error correction or ‘FEC’systems)” (Pet. 19; Ex. 1003 ¶ 25) is consistent with the ’700 Patent, which discloses methods, systems, and devices for forward error correction for flash memory. Ex. 1001, code (57); see also Ex. 1003 ¶¶ 57, 66 (explaining that error correction coding (“ECC”) includes forward error correction (“FEC”)). For these reasons, we find that a POSITA would have had a bachelor of science degree in electrical engineering, computer engineering, or computer science or a related field, and two years of experience designing, developing, or researching error correction coding systems, which include forward error correction systems.” slip op. at 9

As between Petitioner’s position that the multiple arrows in Wu’s Figure 8 represent multiple data streams (Pet. 36–37; Pet.

      “We find that Dr. Dolecek’s testimony about Wu’s Figure 8 and a “plurality of data streams” is more credible than Dr. Bagherzadeh’s testimony on this topic. Dr. Bagherzadeh testifies that Wu’s scrambler “does not split, copy, or otherwise ‘generate a plurality of partially decoded data streams.’” Id. ¶¶ 100, 108. But that testimony fails to take into account what the depiction of multiple double-sided arrows in Wu’s Figure 8 would have meant to a POSITA, as Dr. Dolecek testifies. Ex. 1003 ¶ 86 (reproducing Wu’s Figure 8 with double-headed arrows between ECC engines 822-0 to 822-M and scrambler 103 shaded yellow to identify a “plurality of partially decoded data streams”). The evidence does not support Dr. Bagherzadeh’s opinion that Wu’s Figure 8 is “incompatible” with Wu’s description and “there’s no way to generate a plurality of data streams from the Scrambler to the ECC Engines.” Ex. 2023 ¶ 109. As Dr. Dolecek explained below, when viewed through the eyes of a POSITA, Wu discloses that the scrambler can generate a plurality of data streams. After quoting from Dr. Dolecek’s deposition testimony (Ex. 2023 ¶ 107 (quoting Ex. 2024, 32:15–22)), Dr. Bagherzadeh asserts that “Dr. Dolecek does not explain how she believes the intra-channel operation of the Scrambler on the ‘one long data stream’ it receives could generate a account Dr. Dolecek’s testimony in response to follow-up questions from Patent Owner. Q So you have found the plurality of data streams in the three arrows of Figure 8 going from the scrambler to the ECC engines? A Yes. . . . Q And how exactly, in your understanding as a person of skill, does the scrambler generate that plurality? . . . THE WITNESS: . . . So the person of ordinary skill in the art would understand that these are multiple arrows here indicated explicitly to suggest parallel operations of the ECC engines. And for them to have parallel operations, a person of ordinary skill in the art would assume that they are receiving inputs at the same time, and the scrambler would, for example, do that by sending descrambled data to different engines at a time, one at a time. . . . Q So how does the scrambler’s function of intrachannel rearrangement generate multiple data streams? . . . THE WITNESS: Once it’s descrambled on a per-block basis, it simply sends that block to a given engine, ECC engine. . . . Q Can the scrambler send out multiple data streams in parallel at the same time? A If it’s designed like that, yes. Ex. 2024, 32:24–34:7 (objections and witness’s false start omitted). Q So describe for me how in Figure 8 that would work for your analysis where the scrambler receiving the data from the multiplexer would then generate the plurality of partially decoded data streams. A Right. Figure 8. So if it receives a long string of data that has already been processed by the 104 unit, it would perform intra- -- intrachannel, if you will, intrablock disarrangement of data.

Accordingly, Petitioner submits that a POSITA would be apprised that “the amount of light emitted from the light-emitting element 310 reaching the cup-shaped sidewall of the package…can be reduced, so that deterioration of the package can be prevented.” Id. (citing Ex. 1007 ¶ 42; Ex. 1026, 14:13–20). Thus, Petitioner argues, removing the silicone sealing layer and replacing it with an air gap would increase the light extraction from the package, thus performing the same function of the sealing layer disclosed in Nichia-825. Id. (citing Ex. 1014 ¶¶ 35, 36). Additionally, Petitioner argues that Omata’s air hole is designed to allow air to flow out of the LED package to help balance the pressure inside the package with the external air pressure during the reflow process. Id. at 6–7 (Ex. 1021 ¶ 39; Ex. 1026, 22:10–19, 32:2–4).

      “We disagree with Patent Owner’s argument because it mischaracterizes Petitioner’s reliance on Torii. Petitioner does not rely on a single structure as disclosing both the claimed source electrode and conductive portions. Rather, as explained above, Petitioner relies on the top portion of Torii’s electrode 13 as the claimed source electrode, and the bottom portions as the claimed conductive portions. That is, even if Patent Owner is correct that the claimed source electrode and conductive portions must be distinct structures, that does not undermine Torii’s disclosure because Petitioner relies on distinct portions of Torii’s larger, single-hashed element labeled electrode 13. Because Petitioner does not rely on the same structure, i.e., the entire electrode 13 of Torii, for each of two distinct claim elements, our conclusion does not conflict with the Federal Circuit’s holding in Becton. See Becton, 616 F.3d at 1254 (holding that a single hinge structure could not be both the claimed spring means and the claimed separate hinged arm); id. at 1255 (noting that “[i]f the hinged arm and the spring means are one and the same, then the hinged arm must be ‘connected to’ itself,” which is “a physical impossibility”) (emphasis added).

For example, we disagree with Patent Owner that Torii and Hebinuma are not analogous art because a skilled artisan “would not have looked to Hebinuma to improve on Torii.” PO Resp. 72–76. The ’867 patent, Torii, and Hebinuma are all in the same field of “power semiconductor device[s] having a trench gate structure.” Ex. 1001, 1:5–8; Ex. 1027 ¶¶ 1–3; Ex. 1030 ¶¶ 1–4.

We also disagree with Patent Owner’s argument that one skilled in the art would not have had a reasonable expectation of success because Hebinuma’s oval-shaped trenches were “substantially more challenging” than Torii’s “well-known and well-studied” rectangular-trench solution. PO Resp. 77 (citing Ex. 2013 ¶¶ 128–130). Instead, we agree with Petitioner that one skilled in the art could reasonably expect success because the change “requires only minor changes to the photolithography mask” (Pet. 72; see Ex. 1002 ¶ 364), and because both Torii and Hebinuma expressly teach different trench shapes (see Ex. 1030 ¶ 116 (teaching that “the corner portion of the aperture . . . may be rounded”); Ex. 1027 ¶ 49 (teaching that “the contact trench Tc can be formed under similar conditions . . . with the exception of changing the patterning shape”)).” slip op. at 18
