    “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.

    “a contact surface of said thermo-roller is heated to an elevated temperature of at least 250°F.” Petitioner shows persuasively that the temperature limitation is taught by the combination of Fugitt and Papermaking. Pet. 32–34. Fugitt discloses that “[t]he rolls of the calender may be steam heated.” Ex. 1004 ¶ 26. In a section titled “Heated Rolls,” Papermaking discloses that “Steam can be used up to 170°C [338°F] surface temperature.” Ex. 1010, 95, 98. Petitioner is thus correct that, “[w]hile Fugitt teaches that a hot calender may be steam heated, Papermaking clarifies that one of ordinary skill in the art would understand that steam heated thermo-rollers may reach up to 338°F.” Pet. 36. Based on these disclosures, we are persuaded by Mr. Zotterman’s testimony that it would have been “obvious to heat the thermo-roller of Fugitt to at least 250°F.” Ex. 1003 ¶ 159. combine Fugitt and Papermaking because of Papermaking’s status as a “trusted handbook[],” because both references disclose a method of manufacturing a paperboard structure with hot calendering,” and “because of the known advantages of heated rollers.” Pet. 36–37; Ex. 1003 ¶¶ 157, 159, 162. Petitioner’s contention is supported by Papermaking’s disclosures that, for cartonboard, “[p]recalendering is used before the coater to reduce roughness and porosity” and “[h]igh thermo roll temperatures (in some cases over 200°C) result in bulk savings because of the temperature gradient.” Ex. 1005, 80–82; see also Pet. 38; Ex. 1003 ¶ 164 (citing these disclosures). Papermaking’s disclosed range of “up to 170°C [338°F]” for steam- heated rolls (Ex. 1010, 98), overlaps the claimed range of “at least 250°F.” Patent Owner agrees.

    “Patent Owner’s argument is unpersuasive because the Krames declaration addresses the Patent Owner Response and is relevant to the issues at hand. We start with an important observation: claim 21 (the only independent claim at issue) is an apparatus claim; the claim is directed to a “semiconductor light source.” Ex. 1001, 9:52. One requirement of this apparatus is that it comprise “at least one semiconductor chip” (id. at 10:1) where the “at least one semiconductor chip is a light emitting diode (LED) chip configured to output light at greater than about 40 milliwatts.” Id. at EPRC, 1:34–36. As we explain when addressing claim construction, infra, we adopt Patent Owner’s proposed construction of “a light emitting diode (LED) chip configured to output light at greater than about 40 milliwatts” as meaning “at least one LED chip is capable of emitting light greater than about 40 milliwatts.” See Section III.D, infra (emphasis added). Because of these recitations, Petitioner bears the burden of establishing that the prior art teaches or suggests a semiconductor chip “capable of emitting light greater than about 40 milliwatts.” As explained herein, we determine that in the Petition, Petitioner met this burden by establishing by a preponderance of the evidence that the Krames reference teaches an LED chip that has this capability. Pet. 54 (quoting Ex. 1008, 10). Notably, claim 21 does not require actual operation of anything at greater than 40 milliwatts because claim 21 is not a method claim. Petitioner never had a burden of establishing a method of running the Krames reference’s LED at this power output within a semiconductor light source.” slip op. at 12

    “We agree with Patent Owner that the challenged claims relate to light fixtures, LED packaging, and LED chip layer structure and that the ’961 patent claims reflect “a hybrid of the light bulb art and semiconductor art.” Resp. 19. The prior art of record, for example, Begemann, likewise reflects “a hybrid of the light bulb art and semiconductor art.” Id. (quoting Pet. 28).

While Petitioner’s proposed description of a person having ordinary skill in the art could, in some instances, be sufficient to qualify a person as having ordinary skill, Patent Owner’s proposal is a more complete and accurate description of the level of skill commensurate with the scope of the challenged ’961 patent claims.

    “Based on our review of the record before us, particularly the ’459 patent’s description and Dr. Adnan’s testimony, we agree with Petitioner that the ordinary level of skill in the art does not require the high level of specialized knowledge of control systems suggested by Patent Owner. Moreover, we find that Petitioner’s stated level of ordinary skill in the art is reasonable because it is consistent with the evidence of record, including the asserted prior art.

However, even if Petitioner is correct that the “maximum power output value” is near or equivalent to a pump unit’s output power in intermittent duty, we are still not persuaded that the term “maximum intermittent power” should be tied to the “maximum power output value,” in conflict with the definition provided in the Specification. Petitioner also argues that Patent Owner’s proposed construction is indefinite. Pet. Reply 3. For the reasons discussed below (see supra § II.I.1), we determine that Petitioner has not shown by a preponderance of the evidence that the term “maximum intermittent power,” as defined in the Specification, is indefinite.

    “We agree with Petitioner. Although Figures 4 and 5 of the ’960 patent show keys that are partially surrounded by shadowing or shading, there is no suggestion in the Specification that the “blended shadow” recited in the claims should be limited to only this shadowing. The claim language itself, referring to a blended shadow of the representation of at least one key and the main image (see claim 24), indicates explicitly that the blended shadow incorporates both the key image and the main image and, thus, should not be limited to the shadowing surrounding the keys. Accordingly, based on the full record, we adopt Petitioner’s proposed construction of “blended shadow” as “a portion of a composite image in which the main image is visible through the overlaid image as a result of combining the data from corresponding pixels from the main and overlaid images” for the purpose of this Final Written Decision.

    “We agree with Patent Owner.

At best, Petitioner’s arguments suggest how Gough could be envisioned as using logical operators, but do not explain adequately where or how Gough expressly discloses using logical operators to carry out the blending process. For these reasons, we are not persuaded that Petitioner has shown, by a preponderance of the evidence, that independent claim 1, and claims 2, 3, 5, 7–10, and 12–14 depending therefrom, are anticipated by Gough.” slip op. at 15

See id. at 48 (“[t]o the extent that these features may not be fully disclosed in Buxton, they are clearly disclosed in Harrison”). For purposes of this Final Written Decision, we determine the teachings of Harrison are cumulative to the teachings of Buxton, and therefore, do not address Harrison further.7 4. Claims 1–3, 5, 7–10, and 12–14 Petitioner argues that “Buxton discloses nearly all of the elements and limitations” of the challenged claims. Pet. 42. With respect to claim 1, Petitioner argues that Buxton discloses using alpha blending in accordance with the equation I = αI1 + (1-α)I2, where I is the resulting color intensity, I1 is the color intensity of the foreground image pixel, I2 is the color intensity of the background image pixel, and α is the specified transparency level between 0 and 1. Id. at 43–44 (citing Ex. 1009, 17:17–28). Petitioner argues that Buxton’s alpha blending “permits pixels to be ‘dedicated simultaneously’ to both images in order to produce a composite image” and is an “example of an operation using logical operators to provide different blending effects.” Id. at 44 (citing Ex. 1009, 16:63–17:4). Petitioner contends that although “Buxton may lack explicit disclosure of . . . a touchactivated device (required in claims 1 and 26),” Bier discloses that a touch screen is interchangeable with a mouse.

    “After considering all evidence and arguments, we agree with Patent Owner. In particular, we determine that Petitioner’s arguments do not persuade us that Buxton’s alpha blending equation uses operators that manipulate binary values at the bit level, consistent with our construction of “logical operators.” The alpha blending equation unquestionably involves arithmetic operations, which we find differ from logical operations. Furthermore, Petitioner has not shown persuasively whether any logical operations overlap with any arithmetic operations.

    “To remove Boehm as a prior art reference, the record must establish either: (1) a conception and reduction to practice before the filing date of Boehm; or (2) a conception before the filing date of the Boehm patent combined with diligence and reduction to practice after that date. See Taurus IP, LLC v. DaimlerChrysler Corp., 726 F.3d 1306, 1323 (Fed. Cir. 2013). Under either approach, however, it must be proven that conception occurred prior to November 4, 2002. See id. “Conception exists when a definite and permanent idea of an operative invention, including every feature of the subject matter sought to be patented, is known.” Sewall v. Walters, 21 F.3d 411, 415 (Fed. Cir. 1994). Furthermore, “[t]he conception analysis necessarily turns on the inventor’s ability to describe his invention with particularity. Until he can do so, he cannot prove possession of the complete mental picture of the invention.” Burroughs Wellcome Co. v. Barr Labs., Inc., 40 F.3d 1223, 1228 (Fed. Cir. 1994). Objective evidence that corroborates an inventor’s testimony regarding the conception of the invention is required “because of the danger in post-hoc rationales by an inventor claiming priority.” Invitrogen Corp. v.

    “We agree with Patent Owner that Petitioner’s proposed construction does not take into account properly the “managing the data path” claim language, even given that Petitioner construes only the limitation “a Local Area Network (LAN) routing system” rather than the entire phrase. In any event, we decline to adopt Petitioner’s proposed construction because it erroneously equates a LAN routing system to “a local area network or equivalent circuitry.” We do not view a LAN routing system as being equivalent to a LAN itself or circuitry “equivalent” to a LAN, which Petitioner has not described. We also decline to adopt Patent Owner’s proposed construction, which is not supported adequately. Specifically, Patent Owner does not explain sufficiently why managing the data path necessarily is accomplished “by controlling client devices’ access to the Internet and by controlling access to the client devices from the Internet.” Patent Owner asserts that the Specification of the ’771 patent describes managing the data path “by controlling the client devices’ access to the Internet, such as by requiring authentication before permitting access” and preventing “unauthorized access in the opposite direction by ‘allow[ing] all client devices 30 to share a single external Internet address.’” PO Resp. 5–6 (citing Ex. 1001, 4:1–14); see also Tr. 43:10–14 (stating the Specification “talks about managing as controlling the client devices’ access to the Internet, things like authentication, and controlling access to client devices from the Internet, like sharing a single Internet address”). The Specification, however, does not describe “managing the data path” explicitly, and we are not persuaded that the “managing the data path” claim language necessarily includes the authentication and sharing functions described in the cited passages. As such, Patent Owner’s reliance on the cited passages in its construction seeks to improperly read limitations from the Specification into the claim. See In re Am. Acad. of Sci. Tech. Ctr., 367 F.3d 1359, 1369 (Fed. Cir. 2004) (“We have cautioned against reading limitations into a claim from the preferred embodiment described in the specification, even if it is the only embodiment described, absent clear disclaimer in the specification.”). Dr. Tewfik testifies that “[i]n computer networking, routing systems allow data to be exchanged between networks by forwarding data to a recipient device in one network from a sending device in another network.” Ex. 2004 ¶ 10. Dr. Tewfik further testifies that, “[i]n the ’771 patent, the LAN routing system is the LAN [R]outer 16,” and the LAN routing system allows data to be exchanged between the short-range local network and the Internet. Id. ¶ 11. This testimony is not dissimilar to Dr. Roy’s testimony that a LAN routing system “routes (i.e. communicates) data between a client device that is accessible via a short-range wireless interface and the Internet that is accessible [via] a long range Internet access interface.” Ex. 1012 ¶ 18. Thus, Dr. Tewfik and Dr. Roy essentially are in agreement that a routing system directs (i.e., exchanges, routes, or communicates) data between networks. This meaning is consistent with the Specification of the ’771 patent, which describes LAN Router 16 as “direct[ing] traffic from the access point 12 to the Internet 20 via the fixed WAN interface 18.” Ex. 1001, 3:33–34. Therefore, applying the broadest reasonable interpretation of the claims in light of the Specification, we interpret the phrase “a Local Area Network (LAN) routing system managing the data path between said wireless access point and said Internet access interface” to mean “a system that directs data between a local area network and the Internet by managing the data path between a wireless access point and an Internet access interface.”” slip op. at 8
