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.

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

“The question before us, therefore, is whether the Petitioner’s proffered explanation that it has proposed a different claim interpretation before the Board because the District Court may decline to adopt the narrower claim interpretations it advocates there is sufficient. We find that Petitioner’s explanation is sufficient because it follows the Director’s exemplary logic. 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. The Director and Patent Owner both recognize that, to resolve the dispute over claim interpretation that exists here, a decision-maker must determine “a single claim construction that best captures the true meaning of the patent claim.” Remand 4; PO Remand Br. 3.

“limited to Patent Owner’s proposed “from about 50 Daltons to about 1,500 Daltons.” The cited evidence relied on in the Pomper Declaration to define “low molecular weight” as a term well accepted in the chemical arts relates to metabolomics and metabolites. See Ex. 1002, 169, (specifically, ¶ 17 of Dr. Pomper’s declaration). Patent Owner admits that Dr. Pomper’s testimony is about molecules that differ from the claimed imaging and radiotherapeutic agents targeting FAP-α, but argues that the testimony is still relevant for purposes of explanation. Prelim Resp. 21. While it may be relevant, the testimony is not persuasive in light of the Specification. We find the uncontested fact that several of the B moieties alone—without the A moiety or L linker—specifically identified in the ’233 patent fall outside of Patent Owner’s proposed definition persuasive, as we normally do not interpret claim terms in a way that excludes examples disclosed in the specification. See, e.g., Verizon Servs. Corp. v. Vonage Holdings Corp., 503 F.3d 1295, 1305 (Fed. Cir. 2007) (rejecting proposed claim interpretation that would exclude disclosed examples in the specification). The cases cited by Patent Owner supporting that a claim term may be construed to exclude embodiments where the prosecution history supports such construction are factually distinguishable from the instant case as they regard instances of specific prosecution history disclaimer, clear prosecution disavowal, or relate to a specific definition of the terms in the Specification for the term being construed. Here, “low molecular weight” is not defined in the Specification, but, as Petitioner argues (see Pet. 21–25) is characterized as “demonstrat[ing] faster pharmacokinetics and a higher specific signal within clinically convenient times after administration” and that it “can be synthesized in radiolabeled form more easily.” Ex.1001, 13:33–50, 14:56– 16:14, 17:9–20. We are persuaded by the testimony of Dr. Zeglis, Petitioner’s declarant, that compounds weighing over 1500 Da may share those same behaviors, along with certain identified B moieties disclosed as embodiments.

“Thomason are in the same field of endeavor. Thomason describes a camera and method for correctly orientating pictures from the camera. See, e.g., Ex. 1004 ¶¶ 1, 2 29–40, Figs. 3a–3b. In particular, Thomason is interested in rotating and cropping images to reduce the effect of poor orientation. Pet. 9 (citing Ex. 1004 ¶¶ 2, 34, 36). Pacurariu likewise describes aligning and resizing/cropping of a captured image to correct poor orientation. See, e.g., Ex. 1005 ¶¶ 1, 3, 45–56, Figs. 5A–5C. The preponderance of the evidence also supports that a person having ordinary skill in the art would have had reason to combine the Pacurariu’s teachings with Thomason to predictably improve Thomason. Thomason teaches correct rotation of video data and makes use of rotation sensor to correct rotated images. Pet. 19–21 (citing, e.g., Ex. 1004 ¶¶ 4, 27, 29, 35; Ex. 1002 ¶¶ 76–77). Pacurariu similarly uses sensors and measures tilt angle of the camera. Id at 21–22 (citing, e.g., Ex. 1005 ¶¶ 51–52, Fig. 6; Ex. 1002 ¶ 78). Pacurariu further teaches that its tilt data angle can be stored for each “video frame.” Id. at 22 (citing Ex. 1005 ¶ 52). Petitioner, with support from credible testimony of Dr. Katsaggelos, explains how the teachings of Thomason and Pacurariu could be successfully combined. Id. at 23 (citing, for example, Ex. 1002 ¶ 81). A person of ordinary skill in the art could have known that Thomason’s system could be improved by saving rotation data for each video frame and correcting images on a frame-by-frame basis. Id. at 23–24. The testimony of Dr. Katsaggelos is credible in this regard. Ex. 1002 ¶¶ 80–81. Petitioner and Dr. Katsaggelos explain the references’ teachings and, based on these teachings, assert that a person having skill in the art would have had reason to combine with reasonable expectation of success based on those teachings. Reason to combine may properly come from the references themselves. KSR Int’l Co., 550 U.S. at 418 (explaining reason to combine may come from “interrelated teachings of multiple patents”). Based on the evidence presented, Petitioner establishes by a preponderance of the evidence that a person having ordinary skill in the art would have had reason to combine the teachings of Thomason and Pacurariu with a reasonable expectation of success.

“Petitioner asserts that “[a]ll claim terms should be construed according to the Phillips standard,” and that “no formal claim constructions are necessary for purposes of resolving controversies in this proceeding. Pet. 3. We agree. Given the lack of dispute on this record, we do not perceive the need to construe any claim limitation. Claims must be construed “only to the extent necessary to resolve the controversy.” AstraZeneca AB v. Mylan Pharms. Inc., 19 F.4th 1325, 1345 (Fed. Cir. 2021) (quoting Vivid Techs., Inc. v.

“Mr. Bauer further testifies: For electric-powered breast pumps, the only two options for providing electricity to the pump was either via a wire plugged into an outlet or via a battery, as would have been well-known to a POSITA. It would have been obvious for a POSITA to utilize a battery as the power source for Furrer’s pump as it was one of the two available options and would have provided known benefits. Ex. 1003 ¶ 93. As to why this a person of ordinary skill would have chosen the option of a battery powered breast pump, Mr. Bauer testifies that: Selection of battery power for Furrer’s pump would have beneficially provided a portable system that was usable during travel. Additionally, such a configuration would have allowed the user to move freely about a room, or be positioned in a location within a room without being tethered to a wall plug, allowing the user to, for example, sit or lay in the most convenient location while using the system without having to worry about being close to an outlet. Such mobility provided by selecting battery power for Furrer’s pump would have particularly aligned with Furrer’s suggestion for a ‘hands-free’ and discrete solution. Id. (internal citations omitted); see also Ex. 1003 ¶¶ 138, 143, 145 (further discussing the motivation to combine Furrer and Alvarez in the context of Ground 1B). Based on the record before us, without any evidence or argument to the contrary, we determine that Petitioner shows sufficiently for purposes of trial institution that Furrer, alone or in combination with Alvarez, discloses the claimed control unit comprising a battery, and a pump.” slip op. at 23

“Here, Patentee Sciencons AS filed a statutory disclaimer of claim 7 of the ’603 patent. Ex. 2001. Based on our review of Exhibit 2001 and U.S. Patent and Trademark Office public records, we find that the disclaimer of claim 7 complies with the above-listed requirements of 37 C.F.R. § 1.321(a). Accordingly, we treat claim 7 as having never been part of the ’603 patent. See Vectra Fitness, Inc. v. TNWK Corp., 162 F.3d 1379, 1383 (Fed. Cir. 1998) (“This court has interpreted the term ‘considered as part of the original patent’ in [35 U.S.C.] § 253 to mean that the patent is treated as though the disclaimed claims never existed.”). Because post-grant review cannot be instituted based on disclaimed claims, claim 7 is outside the scope of this proceeding. 37 C.F.R. § 42.207(e) (“No post-grant review will be instituted based on disclaimed claims.”); General Elec. Co. v. United Techs. Corp., IPR2017-00491, Paper 9 (PTAB July 6, 2017) (precedential) (denying institution in view of a statutory disclaimer of all the challenged claims).

“Sciencons AS also states that ARTBIO, Inc. is responsible for defending the ’603 patent in this proceeding and requests that ARTBIO, Inc. be included in the caption for this proceeding.2 Paper 4, 1; Paper 7, 1. ARTBIO, Inc. has signed powers of attorney appointing the same practitioners that were appointed by Sciencons AS to transact all business associated with the instant post-grant review proceeding of the ’603 patent. See Papers 3, 4, 7, 8. To date, no objection has been raised to Patent Owner’s request. Given Sciencons AS’s representation that ARTBIO, Inc. is currently the exclusive licensee of the ’603 patent and is responsible for defending the ’603 patent, we grant Sciencons AS’s unopposed request that ARTBIO, Inc. be included in the caption. For convenience we refer to Sciencons AS and the purported exclusive licensee ARTBIO, Inc. collectively as “Patent Owner.” As stated supra, to the extent any party disputes ARTBIO, Inc.’s right to participate in this proceeding or to be included in the caption, the party shall request authorization to brief the issue within 10 business days of this Decision.” slip op. at 3

Patent Owner does not dispute Petitioner’s assertions or offer any claim constructions. See generally Prelim. Resp. Because resolution of Petitioner’s proposed construction is unnecessary to our analyses for purposes of this decision, we do not address the proposal here. See Realtime Data, LLC v.
