“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

Claims 1–9 and 15 are unpatentable over Chung and Olmos-based obviousness grounds; claims 10–14 were not shown unpatentable because the asserted references did not teach the claimed complementary relationship.

“improperly incorporates-by-reference 12 pages of expert testimony via a single sentence.” PO Sur-reply 16 n.2 (citing Pet. Reply 17, which in turn cites Ex. 1026 (Hatch Decl.) ¶¶ 49–66). 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. Accordingly, we find that paragraphs 53–55—the only paragraphs we cite from Petitioner’s range in reaching our conclusion—are not improperly incorporated by reference into Petitioner’s Reply.” slip op. at 66

“provide Petitioner an opportunity to respond under the new construction, and decline to strike Petitioner’s relevant argument and evidence. Cf. 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

“from the expansion portion. We agree with Patent Owner that the wording of this limitation as a whole requires that the “extension necessarily must protrude beyond a longitudinal end of the expansion portion.” Id. at 11. We also agree with Patent Owner that “[u]nder Petitioner’s tenuous theory, an extension in any direction except 90 or 180 degrees would satisfy the claim language since any such direction has a so-called ‘longitudinal component.’” Id. at 13. For these reasons, we disagree with Petitioner’s argument that the purported “longitudinal component” of Chung’s extension satisfies limitation 1[h].” slip op. at 55

“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. Accordingly, we do not rely on this argument offered by Petitioner.” slip op. at 106

“Second, Dr. Wolfe testified that Matsumiya discloses “a shaft” that protrudes from each side of the case. Ex. 1016 ¶ 97. On cross-examination, however, Dr. Wolfe admitted that while Matsumiya could disclose a “split axle,” “normally, you’d presume that it’s a through axle.” Ex. 2012, 85:9– 18. Dr. Wolfe did not explain in his direct testimony how either an axle or split axle would be integrated with or attached to at least one side of the case. Third, Petitioner relied on the express disclosure of Matsumiya, not a modification of Matsumiya, as teaching this element of the claims. See Pet. 16 (relying only on Matsumiya’s disclosure). In its Reply, Petitioner asserts, for the first time, that Matsumiya “could also use a snap hinge,” pointing to Professor Visser’s cross-examination testimony. Reply 13 (citing Ex. 1050, 127:9–11). Professor Visser’s testimony, however, does not support Petitioner’s argument. Professor Visser testified that Matsumiya does not show a snap-on hinge, and that a snap-on hinge would not have the same functionality as an axle. Ex. 1050, 127:18–21. He also testified that the two concentric rings on the arms of Matsumiya are inconsistent with a snap-on hinge. Id. at 128:17–20. Thus, the issue before us is not whether it would have been obvious to modify Matsumiya to include a snap-on hinge or hinge protuberance on the side of the case because that was not the basis set forth in the Petition and upon which we instituted review; rather, the issue is whether Petitioner has shown that Matsumiya discloses a hinge element or hinge protuberance integrated with or attached to at least one side of the case. In light of the record before us, and as detailed in the discussion above, we conclude that Petitioner has not shown that Matsumiya discloses a hinge element or a hinge protuberance “formed on at least one side of the case.” We find that Petitioner has failed to present sufficient evidence to show that Matsumiya discloses this element of the claims, and we find Patent Owner’s evidence in the form of Dr. Wolfe’s cross-examination testimony and Professor Visser’s testimony more persuasive.” slip op. at 22

“Id. at 1:14–23. Accordingly, we find that Kindig’s field of endeavor is hinged enclosures to house appliances that make noise when operated. The ’544 patent states that “[t]he present invention relates to a flash memory apparatus, and more particularly to a flash memory apparatus, wherein a cover is not completely separated from the main body upon being in use so that lost [sic] of the cover is prevented.” Ex. 1001, 1:8–11. The ’544 patent is largely directed to a cover that rotates with respect to a case (as is evident from the parties’, and consequently our, extensive discussion of the hinged connection (i.e., hinge protuberances and hinge holes)), but is not readily disconnected. In fact, the ’544 patent discloses the recited “hooking groove” and “hooking threshold” specifically to prevent the hinge hole from being easily detached from the hinge protuberance. Id. at 3:36–43 (“Furthermore, a hooking groove 34 is preferably formed on the lower periphery of the hinge protuberance 33. A hooking threshold 45 is hooked on the hooking groove 34 and is preferably formed on a rim confining the hinge hole 41 in order to prevent the hinge hole 41 from being easily detached from the hinge protuberance 33 after joining of the hinge hole 41 and the hinge protuberance 33.”). Thus, we find that the ’544 patent’s field of endeavor is hinge assemblies for a flash memory apparatus.” slip op. at 32

“Second, Petitioner asserts that Kindig’s hinge connection “would advantageously help to retain connection between the cover of Matsumiya and the memory card,” id. at 25, but Petitioner has not shown that Matsumiya fails to retain the connection between case and cover or has difficulty doing so. Rather, from our review the record supports that Matsumiya’s cover is securely attached to the case. Additionally, we are unaware of any teaching in Matsumiya of disconnecting the cover from the case. Similarly, the ’544 patent aims to avoid disconnecting the cover from the case, as discussed above. Kindig, however, is directed to an easily detachable cover. Accordingly, Petitioner’s reason—as to why one of ordinary skill in the art would have been prompted to modify Matsumiya by adding the elements of claim 13 from Kindig—lacks a rational underpinning. 3.
