Petitioner asserts the proposed combination of elements suggest a breast pump device that would have used a diaphragm pump including first and second diaphragm housing components and an elastic diaphragm, “in accordance with Fang’s suggestions.” Id. at 25.

Id. at 26 (citing Ex. 1009 ¶ 19 (“The elastic diaphragm 7 is used to prevent milk from flowing into the air pump main unit 8.”). Mr. Bauer testifies: The flexible diaphragm [diaphragm 7 in Fang] forms a watertight and airtight seal around its outer edge. In doing so, the diaphragm prevents the passage of milk from reaching the air pump and facilitates generation of negative pressure during operation. Fang also explains that the elastic diaphragm 7 deforms away from the nipple tunnel when a vacuum is created on a pumping chamber, which then creates negative air pressure in the nipple tunnel when a vacuum is created on a pumping chamber.” slip op. at 28

Whether a district court has already or might in the future decline to adopt constructions that a petitioner proposes in related district court litigation merely reflects the timing of when a dispute over claim interpretation will be resolved.

      “Relying on the declaration testimony of Dr. Mandayam, Petitioner contends that an ordinarily skilled artisan for the ’110 patent “would have a bachelor’s degree in electrical engineering, computer engineering, computer science, or a similar field, along with two years of experience designing or developing wireless networks, including long-term evolution LTE/4G or 5G new radio (NR) cellular technology.” Pet. 12. Petitioner additionally contends “[a]dditional education might substitute for some of the experience, and additional substantial experience might substitute for some of the educational background.” Id. Patent Owner “utilizes Petitioner’s proposed level of skill in the art.” Prelim. Resp. 2. Based on this record, we adopt Petitioner’s articulation of the level of ordinary skill in the art, which is consistent with the ’110 patent and the asserted prior art, and we apply it in our obviousness evaluations below. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (the prior art, itself, can reflect appropriate level of ordinary skill in art).

      “institute an inter partes review. The standard for instituting an inter partes review is set forth in 35 U.S.C. § 314(a), which provides that an inter partes review may not be instituted unless “there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” The Supreme Court has held that the Board, in a decision to institute under 35 U.S.C. § 314(b), may not institute review on less than all claims challenged in the petition. SAS Inst. Inc. v. Iancu, 138 S. Ct. 1348, 1355–56 (2018). Moreover, in accordance with our rules, “[w]hen instituting inter partes review, the Board will authorize the review to proceed on all of the challenged claims and on all grounds of unpatentability asserted for each claim.” 37 C.F.R. § 42.108(a) (2024); see also PGS Geophysical AS v. Iancu, 891 F.3d 1354, 1360 (Fed. Cir. 2018) (interpreting the statute to require “a simple yes-or-no institution choice respecting a petition, embracing all challenges included in the petition”). Applying those standards, and upon considering the Petition, the Preliminary Response, and the evidence of record, we determine the information presented a reasonable likelihood that Petitioner would prevail in establishing the unpatentability of at least one of the challenged claims of the ’639 patent. Accordingly, we institute an inter partes review.” slip op. at 2

Patent Owner agrees “that claim construction is not required to resolve any issues.” Prelim. Resp. 3.

      “We find that Petitioner has shown sufficiently on this record that the combination of Fakoorian-1 and Takahashi teaches limitations [1d] and [1e]. See Pet. 21–28. As Petitioner argues, Fakoorian-1 includes multiple SPS configurations and teaches that configuration parameters, related to a first and a second SPS configuration, may be sent to the UE in one or more RRC messages. See Pet. 21, 23–24. These parameters include a “periodicity,” “CS-RNTI,” “HARQ process number,” and “service type.” Id. at 21, 24. Petitioner has also shown sufficiently, based on the testimony of Dr. Mandayam, which at this stage stands unrebutted, that a person of ordinary skill in the art would have understood that a “HARQ process number” is “used to indicate which [SPS] configuration(s) are to be” released, and Fakoorian-1’s UE acknowledges the “release by transmitting the acknowledgement in a codebook through a physical uplink control channel (PUCCH) resource.” Id. at 23. As Dr. Mandayam testifies, a person of ordinary skill in the art would have understood, based on Fakoorian-1, that a HARQ process number indicates an identifier for the HARQ codebook to be used by the UE to transmit the acknowledgment. Id. (citing Ex. 1003 ¶ 84). Dr. Mandayam provides sufficient reasoning, at this stage, to support his opinion, so we do not agree with Patent Owner that this testimony is conclusory. See Ex. 1003 ¶¶ 80–84. Thus, on this record, we find that this testimony is sufficient.” slip op. at 15

Patent Owner does not contest Petitioner’s arguments as to these remaining limitations. Also, Dr. Ding’s testimony is currently unrebutted.
