“review of claims 1–17, 20, 21, 24–26, and 29–34 of the ’682 patent. Paper 2 (“Pet.”), 1, 3. Patent Owner, Hangzhou DAC Biotech Co., Ltd., filed a Preliminary Response (Paper 9, “Prelim. Resp.”). We initially determined that the information presented in the Petition did not establish a reasonable likelihood that Petitioner would prevail with respect to at least one of the challenged claims, and did not institute inter partes review. Paper 17. Petitioner requested Director review of our decision denying institution (Paper 18 (“Request”)). The Director delegated review of the decision to a Delegated Rehearing Panel (“DRP”). Paper 19. Patent Owner was granted the option to file a response to Petitioner’s Request (Paper 22 (“Request Resp.”)). The Delegated Review Panel vacated our decision and remanded the case to this panel with a revised claim construction for claim 1. Paper 23 (“DRP Dec.”). On August 30, 2024, we instituted an inter partes review after remand from the Director. Paper 25 (“Inst. Dec.”). Patent Owner subsequently filed a Patent Owner Response (Paper 31, “Resp.”), Petitioner filed a Reply (Paper 36, “Reply”), Patent Owner filed a Sur-reply (Paper 44, “Sur-reply”), and Petitioner filed a Sur-sur-reply (Paper 48, “Sur-sur-reply”).” slip op. at 2

“The only significant difference between the positions of Petitioner and Patent Owner is that Patent Owner would require that a skilled artisan have coursework or training or work experience in multimedia systems in addition to the other requirements. Otherwise, the positions of the parties are similar. Based upon this record and the qualifications on which the parties and their experts agree, we determine that a person of ordinary skill in the art to which the ’669 patent relates would have at least a Master of Science Degree (or higher degree) in an academic area emphasizing electrical engineering, computer engineering, or a similar technical Master’s Degree; or alternatively, a Bachelor’s Degree (or higher degree) in an academic area emphasizing electrical engineering, computer engineering, or an equivalent field with two or more years of work experience in a relevant field or relevant industry experience.

“However, we do agree with Patent Owner that Petitioner’s contention that the cited combination of teachings is supported “because of the structural similarity between Swafford’s and Masumoto’s devices” (Pet. 54– 55) does not provide a motivation to combine. PO Resp, 47–48. The only structural similarity relied on by Petitioner in support of this argument is that Swafford and Masumoto both disclose use of LCDs. See Pet. 54–55. Petitioner provides an inadequate explanation as to how or why the use of LCDs which are a common form of video displays would motivate the combination of the relied-upon teachings. But, this deficiency does not undermine the persuasiveness of Petitioner’s overall showing of motivation to combine. After considering all the arguments and evidence offered by the parties, we determine that Petitioner shows that a person of ordinary skill in the art would have been motivated to combine the relied-upon teachings of Swafford and Masumoto with a reasonable expectation of success.” slip op. at 48

We find that many of the paragraphs within the cited range (i.e., Hatch Declaration paragraphs 49–66) appear to have a tenuous connection to the proposition for which Petitioner cites these paragraphs. See Pet. Reply 17. That said, we find that paragraphs 53–55 directly relate to Petitioner’s proposition in the Reply, i.e., that “Petitioner’s experts explain why a [person of ordinary skill in the art] would rely on a cross-sectional view over a perspective view for making the determination in question, because only the cross-sections provide the needed side view directly orthogonal to the positions of the yellow expansion portion and the end of the dovetail.” Id.

Axonics, 75 F.4th at 1383 (“[W]hen the Board adopts a new claim construction following institution, an IPR petitioner must have adequate notice and an opportunity to respond under the new construction.”). Like in Axonics, in its new arguments on Reply, Petitioner here relies on the same embodiment from the same prior art reference that it relies on in the Petition to support the same legal argument, i.e., that Olmos’s Figure 16 embodiment discloses the “complementary with one another” limitation of challenged claims 10– 14. See Axonics, 75 F.4th at 1384; see also Apple Inc. v. Andrea Elecs. Corp., 949 F.3d 697, 706 (Fed. Cir. 2020) (permitting petitioner to elaborate in reply on an unpatentability theory presented in the petition). Moreover, we permitted Patent Owner to file (and it indeed did file) a sur-reply brief and expert declaration that addressed Petitioner’s new obviousness theories. Accordingly, both parties had adequate notice of our preliminary construction and an opportunity to respond under that new construction. For these reasons, we deny Patent Owner’s motion to strike.” slip op. at 124

“would have been motivated to add an extension to the Figure 16 embodiment because “an integrally-formed extension advantageously requires fewer parts, which facilitates both manufacturing and use.” Pet. 118. We agree with Patent Owner that this argument is unavailing. PO Resp. 50. Petitioner’s combination entails adding an extension (from Figure 8) to an embodiment lacking one (Figure 16). We agree with Patent Owner that adding a new component (whether separately or integrally) can in some instances complicate manufacturing/assembly and increase costs. See id. (citing Ex. 2013 (Culbert Decl.) ¶ 115). Petitioner has not sufficiently demonstrated that the proposed combination in this instance would reduce complexity or facilitate the manufacturing process.

“We construe “cluster of individual sensors” as “a group of individual sensors or components of individual sensors positioned close together.” Pet. 6–7; Prelim. Resp. 11–12. This interpretation is consistent with an ordinary meaning of “cluster” which includes “a group of things or people that are close together” (Pet. 6) and the claims, which recite “a cluster of individual sensors resides on or near said in-cabin surface of said windshield.” This interpretation is consistent with the ’590 patent specification, which discloses that housing 10 is divided by wall 16 into adjacent first and second compartments 18, 20. Ex. 1002, 3:29–31, Fig. 2. One embodiment contains rain sensor 26 in first compartment 18 and printed circuit board 30 bearing a compass sensor 30 in second compartment 20. Id. at 5:62–6:12, 7:52–55, Figs. 2, 8. The ’590 patent specification discloses that the housing may accommodate a plurality of electrical accessories. Id. at 6:42–44. The ’590 patent further discloses that component 30 “can be any of a number of sensors or circuits which can be made small enough to fit in the compartment 20.” Id. at 7:64–67 (emphasis added). Preferably, component 30 is provided as a unitary module received in compartment 20. Id. at 7:67– 8:1. An ordinary meaning of “any” is one or more.
