“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

“proposed combination based on the argument that a POSITA would have been motivated to switch the layout responsive to a parameter value changing. Pet. 11–15 (citing Ex. 1003 ¶¶ 35–40, 47–52). For example, we agree with Petitioner that a motivation exists to change the layouts to “best suit the condition of [the] patient” because Naghavi expressly describes an “interactive and dynamic” GUI that “may automatically detect changes in health status . . . and automatically react and rearrange the available options to best suit the condition” of the patient. Ex. 1005 ¶ 63. The supporting expert testimony persuasively relies on this aspect of Naghavi when concluding that “such a change in the severity of a parameter can indicate a change in the patient’s health that may require close monitoring” and a POSITA “would have been motivated to implement this approach of the combination in order to achieve” Naghavi’s objectives. Ex. 1003 ¶ 48 (citing Ex. 1005 ¶ 63); see also Pet. Reply 23 (“[T]he rearrangement of parameters, as already suggested by Naghavi and implemented according to Hochstedler, advantageously ensures an easy-to-use user interface, e.g., by highlighting information that has changed to warrant user attention.” (citing Pet. 13–14; Ex. 1003 ¶¶ 42–43)); Ex. 1003 ¶¶ 42–43.” slip op. at 51

“preponderance of the evidence that the combination of Naghavi, Hochstedler, and Burnes discloses all of the limitations in claim 1. b. Motivation to Combine After summarizing its proposed combination, Petitioner provides a number of reasons for combining the references. Pet. 9–17. Petitioner breaks its motivation to combine arguments into three separate categories that we address below. See id. at 13–17. Patent Owner raises a number of arguments in support of its contention that “a POSITA would not have been motivated to combine the references to replace a measured value of one parameter with the measured value of another parameter,” which we address in the context of Petitioner’s arguments below. See PO Resp. 44–57. Many of Patent Owner’s arguments rely on Patent Owner’s proposed claim constructions for “replaced” and “measured value,” which we do not adopt for the reasons discussed above. For example, the first sentence in Patent Owner’s argument contends that “Naghavi, Hochstedler and Burnes do not disclose using the same screen area to display two currently measured parameters,” but we do not read the claims as requiring the display of “two currently measured parameters” consistent with Patent Owner’s construction for “measured values.” See id. at 44 (citing Ex. 2042 ¶ 125). Such arguments lack weight given that we have rejected their premise, and although Patent Owner’s arguments are suffused with references to its claim constructions, we attempt to identify where Patent Owner does not rely on those constructions in our analysis below.” slip op. at 47

“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

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.

“PO Resp. 9. Patent Owner asserts “a POSA would have understood the plain and ordinary meaning of the term ‘acoustic signal’ [is] a signal that is transmitted as a sound wave through the ambient environment.” Id.; Ex. 2003 ¶ 25. Patent Owner therefore asserts a POSA would have understood the claimed “frequency modulated ECG acoustic signal” is a signal that is transmitted as a sound wave through the ambient environment, [and excludes] signals transmitted by electronic or wireless radio means, because claim 1 requires the acoustic signal to be “received from a built-in microphone of the smartphone.” PO Resp. 9; Ex. 2003 ¶ 26.

“that Vyshedskiy’s disclosure of a list of preferred carrier frequencies represents a permissible “obvious to try” situation. In KSR, the Supreme Court stated that a person of ordinary skill has good reason to pursue the known options within his or her technical grasp. If this leads to the anticipated success, it is likely the product not of innovation but of ordinary skill and common sense. In that instance the fact that a combination was obvious to try might show that it was obvious under § 103. KSR, 550 U.S. at 421. And simply because the prior art “discloses a multitude of effective combinations does not render any particular formulation less obvious.” Merck & Co. v. Biocraft Labs., Inc., 874 F.2d 804, 807 (Fed. Cir. 1989). The instant facts represent a situation where, at the time of invention in 2010, it would have been obvious to try the known carrier frequencies of Vyshedskiy for modulation of the acoustic ECG signal of Albert in the claimed frequency range of 6 kHz to 20 kHz because these carrier frequencies would have been obvious alternatives to try to address Vyshedskiy’s disclosed design need for simultaneous measurement of heart sound auscultation and ECG heart cycle.
