“Patent Owner does not address the level of skill. See Prelim. Resp. Because Petitioner’s proposed level of ordinary skill in the art is consistent with the field of the invention of the ’275 patent and not disputed by Patent Owner, for purposes of this Decision, we adopt Petitioner’s formulation of the person having ordinary skill in the art.7 7 If Patent Owner disagrees with this formulation of the level of skill in the art, it must raise that disagreement in its Response. If a different level of skill would affect the outcome in this case, the parties must brief that issue as well. The failure of Patent Owner to describe how a different level of skill in the art is determinative will be a forfeiture of that argument. If there is a dispute regarding the level of ordinary skill in the art, then the parties are also encouraged to submit evidence, other than conclusory expert testimony, that supports their position.

On remand, the Board held claim 9 unpatentable as obvious over Agin and Chen, finding Agin teaches the initial power adjustment and the combination teaches the offset determination.
RulingsRemand decision- RemandOther
“Reviewing Patent Owner’s arguments and Petitioner’s assertions, we remain persuaded that one of ordinary skill in the art would have applied the previous power level, i.e., the power level prior to the interruption, and also an offset according to the process illustrated in Agin’s Figure 2. Agin makes clear that its processes in Figure 2 are run “[i]f transmission is not resumed after a transmission interruption” and “[i]f transmission is resumed after a transmission interruption.” Ex. 1004 5:44–50. Figure 2 of Agin is used to make a determination of what the power level would be after an interruption, and that process should be followed, for the first transmission, as well as subsequent transmissions. Agin does not address a separate procedure for the initial transmission after an interruption because the process in Agin’s Figure 2 is generally applicable to all interruptions. This understanding comports with Dr. Ding’s testimony, discussed above, that we credit. See Ex. 2002, 115:13–16, 113:16–22, 110:13–16.” slip op. at 23

Petitioner cites multiple rationales for the combination of Agin and Chen, including the benefits of Chen’s techniques, the predictability of such a combination, improvements in performance and transmission quality, reducing uncertainty, smoothing power levels, and argues that these approaches would have had a reasonable expectation of success. Pet. 17–19.

We also acknowledge that Dr. Jackson’s testimony is clear and he testifies that Chen is sufficiently different and that the processes of Chen would not be readily adaptable to Agin. Weighing the testimonies of Drs. Ding and Jackson, we determine Dr. Ding’s testimony to be more persuasive as to the combination. For example, we concur with Dr. Ding that handover is directly related to communication interruptions in that the handover mechanism exists in order to try to avoid interruptions.

“to combine Johnson and Moss is inadequate. See Prelim. Resp. 20–24. We tend to agree. In the “Motivation to Combine Johnson and Moss” section, the Petition first asserts that “Johnson and Moss are in the same field of endeavor,” which is insufficient without more to provide a motivation. See, e.g., Sisvel Int’l S.A. v. Sierra Wireless, Inc., 82 F.4th 1355, 1364 (Fed. Cir. 2023). The Petition then asserts that “[t]o provide enhanced flexibility, [one of ordinary skill in the art] in possession of Johnson would look to Moss to incorporate a plurality of delay elements to the data strobe signal.” Pet. 22. This is not persuasive because (a) Petitioner argues that Johnson already provides a plurality of delay elements, (b) Petitioner fails to explain where or how additional delay elements from Moss would be added to Johnson, and (c) Petitioner fails to explain how or why the modification would “provide enhanced flexibility,” or even what “enhanced flexibility” might mean in 9 “a first sampling circuit to sample the first delayed data signal based on the strobe signal” 10 “a second sampling circuit to sample the second delayed data signal based on the received strobe signal” this context. Petitioner also argues that “Moss further discloses that the size of the data path – i.e. the number of data pins in each data path – is a design choice well within the knowledge and ability of a POSITA, and expressly recites examples of 4, 8, and 16-bit wide data paths.” Pet. 23. We agree that varying the width of the data path would have been within level of ordinary skill and would have depended on the particular application, but the Petition fails to explain how or why that would have made it obvious to incorporate various elements of Moss into Johnson.” slip op. at 19

“We do not agree with Patent Owner’s argument because it advocates for the importation of functional limitations from the ’794 Patent Specification into the claims––namely the disclosure that the bypass circuit continues to conduct electricity, and keeps the remaining lights lit, even when one or more individual lighting elements in the series are burned out, missing, or defective. See PO Resp. 8–9. 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. Moreover, the language that Patent Owner wishes to import into the claim from the Specification is functional language that describes the function of the resistor bypass circuit. As explained below in the section addressing the subsequent claim recitation, functional language is evaluated in view of the applied prior art to determine whether it imparts additional structure to distinguish the claimed invention over the prior art.

Petitioner also points out that the term inherent is not used in the ’794 Patent Specification. See id. Patent Owner does not explicitly address “inherent resistance” in terms of a claim construction. See Prelim. Resp. 6–9. In any event, when addressing an alleged lack of motivation to combine the teachings of the references, Patent Owner compares and contrasts incandescent bulbs, which according to Patent Owner, have an inherent resistance, and LEDs, which according to Patent Owner, do not exhibit self-regulating resistance. See Prelim. Resp. 20 (citing Ex. 2002 ¶ 67); see also id. at 23 (similar argument, citing Ex. 2002 ¶ 73). Indeed, Patent Owner asserts that “the word resistance is not useful when describing LEDs as opposed to incandescent bulbs. . . .

“We do not agree with Patent Owner’s argument because it advocates for the importation of functional limitations from the ’252 Patent Specification into the claims––namely the disclosure that the bypass circuit continues to conduct electricity, and keeps the remaining lights lit, even when one or more individual lighting elements in the series are burned out, missing, or defective. See PO Resp. 7–8. 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. Moreover, the language that Patent Owner wishes to import into the claim from the Specification is functional language that describes the function of the resistor bypass circuit. As explained below in the section addressing the subsequent claim recitation, functional language is evaluated in view of the applied prior art to determine whether it imparts additional structure to distinguish the claimed invention over the prior art. Accordingly, for the purpose of institution and to the extent the preamble recitation is limiting, we need not provide an express construction for “[a] resistor bypass circuit for a series lighting circuit.”” slip op. at 7

“least in part on a second message including at least one command in a second format.’” Pet. 4 (citing Ex. 1104, 168–173). The cited portion of the prosecution history shows that the applicant distinguished its claims from the prior art based on different first and second formats. The applicant argued in particular, Applicant submits that [the prior art] is completely silent with regard to “receiving, from the remote server device, a first message that includes at least one command in a first format, wherein the first message is received based at least in part on a second message including at least one command in a second format having been sent from the associated remote computing device.” In fact, [the prior art] never describes commands in different formats. . . . Ex. 1104, 170. Based on the applicant’s argument in this regard, we find that the prosecution history limits the scope of claim 1 to different first and second formats. In other words, the applicant’s argument during prosecution distinguishing its claims from the prior art based on different first and second formats overcomes the presumption based on claim differentiation that claim 1 encompasses first and second formats that are the same. See Fenner Invs., Ltd. v. Cellco P’Ship, 778 F.3d 1320, 1327 (Fed. Cir. 2015) (“Although claim differentiation is a useful analytic tool, it cannot . . . relieve any claim of limitations imposed by the prosecution history.”). Accordingly, claim 1 is limited to different first and second formats.” slip op. at 10

“argument and evidence. As discussed above in the claim construction section, the recited first and second formats are limited to different formats. See supra Part IV.A. To satisfy this aspect of limitation 1D under its theory, Petitioner needs to show that in Danciu the format of the control information sent from the remote control to the server is different from the format of the control information sent from the server to the controlled device. The cited disclosures in Danciu, however, do not teach or suggest that these formats are different. Nor does Petitioner explain adequately how Danciu’s disclosures teach or suggest the two formats are different. We recognize that the control information in Danciu may be “processed” or “repackaged,” as Petitioner asserts, but it is not clear that the control information is processed or repackaged such that the format of the control information sent from the remote control to the server and the format of the control information sent from the server to the controlled device are different. Petitioner does not rely on Mahajan to teach or suggest the recited first and second formats but relies on Mahajan instead as providing “implementation details for transmission of commands for controlling a client.” Pet. 27. Petitioner contends that its proposed combination of Danciu and Mahajan would have provided a system where “Danciu’s remote control would translate commands associated with a first type of media playing application to a generic format, transmit them to the controlled device, which would translate them to a command associated with a second type of media playing application for execution.” Id. at 31. In other words, the controlled device would receive the generic commands sent from the remote control and then translate the generic commands. It is not clear how the proposed combination in this way teaches or suggests the format of a command sent from the remote control to a server is different from the format of a command sent from the server to the controlled device.” slip op. at 17

“Aldrey and Mahajan meets limitation 1D under Petitioner’s second theory. Petitioner only alleges that it would have been obvious to an ordinarily skilled artisan that Mahajan’s RTS Media Abstraction Module could operate at a server like Aldrey’s service provider network 103. Pet. 65. The Federal Circuit has explained that “obviousness concerns whether a skilled artisan not only could have made but would have been motivated to make the combinations or modifications of prior art to arrive at the claimed invention.” Belden Inc. v. Berk-Tek LLC, 805 F.3d 1064, 1073 (Fed. Cir. 2015). Petitioner does not adequately explain why an ordinarily skilled artisan would have considered locating Mahajan’s abstraction module at a server, even if the abstraction module could operate at the server. See In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006) (“[T]here must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.”). We note Petitioner further argues that combining Mahajan and Aldrey would have provided a system where “Aldrey’s end terminal would translate commands associated with a first type of media playing application to a command associated with a second type of media playing application on a STB.” Pet. 66–67; see also id. at 66 (“Mahajan’s server-command teachings could be implemented on Aldrey’s end terminal remote control.”). Arguing that Aldrey’s end terminal would translate commands seems inconsistent with Petitioner’s earlier argument for locating Mahajan’s abstraction module (which translates commands) at Aldrey’s network service provider. See id. at 65–67. Moreover, it is not readily apparent how command translation by Aldrey’s end terminal––rather than Aldrey’s network service provider–– teaches or suggests the format of a command sent from the end terminal to the network service provider is different from the format of a command sent from the network service provider to the STB. Petitioner does not close these logical gaps.” slip op. at 23

“Contrary to Petitioner’s position, Patent Owner met its burden of showing that our Institution Decision should be modified. In our Institution Decision, we relied on claim differentiation when we determined that claim 1 is not limited to different first and second formats. Inst. Dec. 31.

As we noted in our Rehearing Decision, however, the Federal Circuit has explained that “[t]he prosecution history modifies the scope of a claim term if ‘the patentee distinguished that term from prior art on the basis of a particular embodiment, expressly disclaimed subject matter, or described a particular embodiment as important to the invention.” Reh’g Dec. 8 (quoting Sentry Protection Prods., Inc. v.
