Before LOURIE, SCHALL, and TARANTO, Circuit Judges. TARANTO, Circuit Judge. Lectrosonics, Inc. petitioned the Patent and Trade- mark Office to institute an inter partes review, under 35 U.S.C. §§ 311–19, of all claims of U.S. Patent No. 9,336,307, which is owned by Zaxcom, Inc. After institu- tion of the requested review, Zaxcom filed a motion to re- place the original claims 1–14 with fourteen corresponding claims—substitute claims 15–28—if the Patent Trial and Appeal Board held the original claims unpatentable. The Board issued a final written decision holding all original claims unpatentable, and it therefore addressed Zaxcom’s proposed substitute claims, which it allowed to be added to the patent because Lectrosonics had not proved them un- patentable. Lectrosonics, Inc. v. Zaxcom, Inc., No. IPR2018-00972, 2019 WL 5849856, at *29 (P.T.A.B. Nov. 7, 2019). Zaxcom appeals the Board’s rejection of the orig- inal claims, and Lectrosonics appeals the Board’s approval of the substitute claims. We affirm both determinations.

ZAXCOM, INC. v. LECTROSONICS, INC. 3

I The ’307 patent describes and claims a system and method for recording and processing audio received from wireless devices. The specification describes at least the following arrangement: Each of a plurality of wireless de- vices, upon picking up audio, both self-records the audio and sends it wirelessly to a remote recorder. ’307 patent, col. 2, line 54, through col. 3, line 14. The recordings are time-synchronized so that “multiple individually recorded audio tracks” can be “combined into one or more multi- track audio files.” Id., col. 4, lines 3–14. One reason for the local recording is that wireless transmission to the remote recorder may be imperfect due to dropout or noise, id., col. 4, lines 15–25, and the locally maintained data can be used for repair—specifically, to replace corrupted data received wirelessly at the remote recorder, id., col. 12, lines 59–63. The patent had two independent original claims: an ap- paratus claim (claim 1) and a method claim (claim 12). Both claims require wearable local audio devices that wire- lessly transmit local audio to a remote recorder and also locally record audio in the memory of the device. And both claims required that local audio data be “combined” with remotely recorded audio data. See id., col. 23, lines 22–42 (claim 1); id., col. 24, lines 15–32 (claim 12). We agree with the Board’s construction of the claims to encompass both embodiments described in the specifica- tion, i.e., both the repair of dropouts and the creation of a multitrack file. Lectrosonics, 2019 WL 5849856, at *4. Un- der the claims’ broadest reasonable interpretation (BRI), local and remote audio data may be “combined” either to repair corrupted audio data received by the remote re- corder or to create a multitrack audio file. In adopting that construction under the BRI standard, the Board correctly rejected Zaxcom’s argument for a requirement that the claimed “local audio data” and “remote audio data” derive from the same source (i.e., the same local audio event). Id. Case: 20-1350 Document: 71 Page: 4 Filed: 02/18/2022

Given the claim construction, the Board had substan- tial evidence to support its findings underlying the conclu- sion that claims 1–11 were unpatentable for obviousness over Strub (U.S. Patent No. 6,825,875) when combined with either Nagai (U.S. Publication No. 2002/0159179 A1) or Gleissner (U.S. Publication No. 2004/0028241 A1), as well as its finding that claims 12–14 were anticipated by Strub. The Strub patent discloses a “small, lightweight, wearable recording unit,” Strub, col. 4, lines 29–31, that records and transmits audio data that can be used by other units, id., col. 12, lines 4–39, and “blend[s]” audio record- ings from different devices, id., col. 86, lines 1–9. The Board had substantial evidence for its determination that Strub alone anticipated claims 12–14. Lectrosonics, 2019 WL 5849856, at *11. And it also had substantial evidence that a relevant artisan would have been motivated to com- bine Strub with either Nagai or Gleissner, both of which undisputedly disclose the “audio input port” of claims 1–11. Id. at *7–10. Zaxcom argues, as to claims 1–11, that no obviousness conclusion should be drawn because its evidence of indus- try praise and long-felt need should have outweighed the above-recited determinations based on the prior art. But given the adopted claim construction, the Board deter- mined that Zaxcom’s evidence of such objective indicia lacked the nexus to the claimed invention required to alter a conclusion of obviousness that would be justified based on the prior-art analysis. Id. at *10–11. Zaxcom specifi- cally focused on a Technical Achievement Academy Award, J.A. 4272, an Engineering Emmy Award, J.A. 4304, and declarations from sound mixers, J.A. 4273–78; J.A. 4281– 84, praising Zaxcom’s wireless recording systems. The Board reasonably found that the praise was primarily di- rected to the systems’ critical feature of dropout repair, while the claims of the ’307 patent, under the BRI construc- tion properly adopted, are broadly directed to wirelessly transmitting audio data and combining local and remote Case: 20-1350 Document: 71 Page: 5 Filed: 02/18/2022

ZAXCOM, INC. v. LECTROSONICS, INC. 5

audio data from a plurality of devices—a technique already known in the prior art. The evidence, in short, says noth- ing to suggest non-obviousness of one of the two types of systems and methods within the claims’ coverage. We therefore agree with the Board that, based on that finding, the objective indicia evidence is insufficient to overcome the prior-art evidence of obviousness. See Intercontinental Great Brands LLC v. Kellogg North America Co., 869 F.3d 1336, 1343–44, 1347 (Fed. Cir. 2017) (overall obviousness determination is a legal one based on weighing of prior-art and objective-indicia facts). Thus, the Board properly held claims 1–11 unpatentable for obviousness. II On Lectrosonics’s cross appeal, we affirm the Board’s determination that the substitute claims are not unpatent- able.
