In its opinion, the Federal Circuit reversed our “determination of no motivation to combine Doo and Amira” and remanded for further proceedings to evaluate whether claims 1–6 and 11–20 (“the Remanded Claims”) of U.S. Patent No. 11,004,271 B2 (“the ’271 patent,” Ex. 1001) are unpatentable in view of Petitioner’s obviousness challenge over Doo and Amira. Medivis, slip op. at 9–10. We have jurisdiction under 35 U.S.C. § 6(b). We issue this Final Written Decision on Remand pursuant to 35 U.S.C. §§ 144, 318 and 37 C.F.R. § 42.73 in an inter partes review involving Medivis, Inc. (“Petitioner”) and Novarad Corp.

For the reasons discussed below, after considering the entirety of the record in light of the Federal Circuit’s directives in Medivis, we hold that Petitioner has demonstrated, by a preponderance of the evidence, that claims 1–6, 11, and 20 are unpatentable; however, Petitioner has not demonstrated, by a preponderance of the evidence, that claims 12–19 are unpatentable.” slip op. at 2

“We agree with Petitioner that the term “3D slices” has no apparent connection to the phrase “direct volume rendering.” Patent Owner’s argument appears to be that DVR “requires an image of the entire anatomical volume that is neither feature-specific nor segmented, [which] would seemingly require that all inner layers be displayed.” Reply 4; see Sur-reply 6–10 (not disputing Petitioner’s characterization). But, as Petitioner notes, the specification directly undermines this by teaching “display [of] a slice of the 3D data instead of a volume of the 3D data.” See Reply 4 n.2 (quoting Ex. 1001, 5:34–35). In other words, to the extent DVR would depict an image of the entire anatomical volume, displaying 3D slices “instead of a volume of the 3D data” implies the opposite of DVR. Even if “3D slices” somehow implied DVR, Patent Owner’s position is still untenable. Claim 1 does not recite “3D slices.” Instead, claim 1 recites “3D data” and “inner layers.” Ex. 1001, 18:54–65. Patent Owner fails to clarify the relationship between “slices,” “3D data,” and “layers,” and its expert even admits that slices and layers are two different things. See PO Resp. 13; Ex. 1022, 32:7–16 (agreeing that the words “slice” and “layer” are not “synonyms”), cited in Reply 4. We also agree with Petitioner that dependent claim 3 distinguishes slices and layers by reciting “slices of the projected inner layer.” Reply 4 (quoting Ex. 1001, 19:3–10). Thus, even if 3D slices somehow implied DVR, the language of claim 1 does not support limiting the claim this way.” slip op. at 12
- Novelty / Anticipation (§102) › Prior-art status of a reference › Printed publication / public accessibilityPrinted publication establishedDecided for petitioner
“The determination of whether a document was publicly accessible “involves a case-by-case inquiry into the facts and circumstances surrounding the reference’s disclosure to members of the public.” Medtronic, Inc. v. Barry, 891 F.3d 1368, 1380 (Fed. Cir. 2018). For instance, courts routinely rely on the Wayback Machine to determine when a reference was first made available to the public. Valve Corp. v. Ironburg Inventions Ltd., 8 F.4th 1364, 1374 (Fed. Cir. 2021) (“District courts have taken judicial notice of the contents of webpages available through the Wayback Machine ‘as facts that can be accurately and readily determined from sources whose accuracy cannot reasonably be questioned.’”). We disagree with Patent Owner’s argument that “Medivis cannot rely on additional prior art”—Exhibits 1023 and 1024—“that was submitted after its Petition to carry its burden without leave from the Board.” Sur-reply 4. As Patent Owner did not file a motion to exclude these exhibits, we decline Patent Owner’s invitation to disregard them. We also find Petitioner’s Reply argument proper because it directly responds to Patent Owner’s contention that Petitioner did not prove the public accessibility of Amira. See Chamberlain Grp., Inc. v. One World Techs., Inc., 944 F.3d, 919, 925 on issues previously raised.”). Petitioner’s Reply argument appropriately elaborates on the Petition’s contention that Amira was publicly accessible. Patent Owner also does not dispute the substance of Petitioner’s evidence. For example, Patent Owner does not address the substance of Mr. Frank-White’s declaration. We find that this evidence, including Mr. Frank- White’s declaration testimony, persuasively supports the public availability of Amira as of the date shown in the Wayback Machine URL.

“Ex. 1163 ¶ 37 (citing Ex. 1003 ¶ 71; Ex. 1005, 1–3). We credit Dr. Bajaj’s testimony which is unrebutted and supported by the record.

Menon’s description of building on and enhancing the teachings of Trefethen—the earlier work of the same research group at Cornell—by adding MEX routines to achieve high-performance parallel computing and extensibility for MATLAB, demonstrates a classic motivation for a POSITA to combine. RS6000 is specifically referenced in Menon-Trefethen and adds operational details of the parallel operating platform that teach a POSITA how to implement the MultiMATLAB system with a reasonable expectation of success.

We find that Osterhout teaches the dynamic eye tracking mechanism is in optical communication with the lens, consistent with its ordinary and customary meaning, because in Osterhout the user’s eye receives optical communication in the form of light transmitted from the translucent lens, and the camera of the dynamic tracking mechanism, in turn, receives optical communication in the form of light from the user’s eye.

“Pharms. Inc. v. Amino Chemicals Ltd., 715 F.3d 1363, 1374 (Fed. Cir. 2013)). Accordingly, Patent Owner applies a different definition of “side,” in claim 1’s recitation of “an illumination area on at least two sides of the fan at top of the body,” to that definition used to understand “side[s] of the body,” discussed above. Specifically, Patent Owner argues that Petitioner’s dictionary definition of “side,” including “an area next to something” applies to “an illumination area on at least two sides of the fan at the top of the body.” See id. at 8–9.” slip op. at 17

“When rehearing a decision on petition, the Board will review the decision for an abuse of discretion. See 37 C.F.R. § 42.71(c). An abuse of discretion may be determined if a decision is based on an erroneous interpretation of law, if a factual finding is not supported by substantial evidence, or if the decision represents an unreasonable judgment in weighing relevant factors. See Arnold P’ship v. Dudas, 362 F.3d 1338, 1340 (Fed. Cir. 2004). The party challenging the decision has the burden of showing the decision should be modified, and the request for rehearing “must specifically identify all matters the party believes the Board misapprehended or overlooked, and the place where each matter was previously addressed” in its papers. 37 C.F.R. § 42.71(d).” slip op. at 2

“II. ANALYSIS In our Decision, we concluded that Petitioner had failed to carry its burden of demonstrating a reasonable likelihood of prevailing that either Shen or Soldano anticipated claims 1–7.

“Owner’s interpretation of “carrier” as meaning “one or more components for supporting ROSA components such as an AWG.” Dec. 9 (quoting Pet. 11). For our analysis of Petitioner’s challenges, we referred to this interpretation of “carrier” as Petitioner’s second alternative construction. Id. We also noted that Petitioner appeared to dispute Patent Owner’s interpretation when it argued that “carrier” should mean “a ceramic or silicon substrate.” Id. (quoting Pet. 10). We referred to this interpretation of “carrier” as the first alternative construction. Id. Rather than resolve this apparent dispute about the meaning of “carrier,” we found that both of Petitioner’s anticipation challenges failed under both interpretations of “carrier.” Id. at 10–26. Because we found that Petitioner had failed to carry its burden regardless of which interpretation of “carrier” applied, we found it unnecessary to resolve the dispute over that interpretation. Id. at 9–10. For the reasons expressed in Parts II.B–C below, we maintain our conclusion that Petitioner has failed to demonstrate a reasonable likelihood of proving that either Shen or Soldano anticipates any claim under either interpretation of “carrier.” Accordingly, Petitioner fails to demonstrate an abuse of discretion in our alleged “refusal” to interpret “carrier.”” slip op. at 3

“Reh’g Req. 14. We cannot weigh Petitioner’s arguments based on its assertions about “caselaw” because Petitioner cited no cases to support its arguments. See id. Nevertheless, we infer that Petitioner intends its statements of “caselaw” to refer to the requirements to make out a case for anticipation. If so, Petitioner demonstrably miscasts what appear to be the legal principles for proving anticipation. As stated in our Decision: “A claim is anticipated only if each and every element as set forth in the claim is found, either expressly or inherently described, in a single prior art reference.” Verdegaal Bros., Inc. v. Union Oil Co. of California, 814 F.2d 628, 631 (Fed. Cir. 1987).” Dec. 7.

“invention of the ’527 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,” and that “[a]dditional education might substitute for some of the experience, and additional substantial experience might substitute for some of the educational background.” Pet. 12 (citing Ex. 1003 ¶¶ 40–43). Patent Owner at this stage of the proceeding does not provide an alternative definition for a level of skill in the art that one would have had at the time of the invention of the ’527 patent or identify any shortcoming in Petitioner’s formulation. See Prelim. Resp. 3–4. For purposes of this Decision on Institution, we adopt Petitioner’s definition of the level of skill for one of ordinary skill in the art. Pet. 12. We view the definition for the level of ordinary skill is consistent with the ’527 patent and the asserted prior art, and we apply it in our analysis below.” slip op. at 6

“discloses the preamble and the remaining limitations of claim 1. Pet. 38–64. Petitioner identifies where the combination of Kim, Dahlman, and Kim966 teaches these limitations, supported with testimony from Dr. Mandayam, which Patent Owner does not specifically rebut at this stage. We determine, on this record, that the combination of Kim, Dahlman, and Kim966 teaches the preamble (whether or not limiting) and the remaining undisputed limitations of claim 1. See LG Elecs., Inc. v. Conversant Wireless Licensing S.A.R.L., 759 F. App’x 917, 925 (Fed. Cir. 2019) (nonprecedential) (“The Board is ‘not required to address undisputed matters’ or arguments about limitations with which it was never presented.”) (quoting In re NuVasive, Inc., 841 F.3d 966, 974 (Fed. Cir. 2016)). We also find that Petitioner has provided sufficiently articulated reasoning, which Patent Owner does not specifically address at this stage, to support combining Kim, Dahlman, and Kim966’s teachings in the manner Petitioner does. Pet. 21–38. 3. Summary In summary, based on the current record, we determine that Petitioner shows a reasonable likelihood that the combination of Kim, Dahlman, and Kim966 renders claim 1 obvious.” slip op. at 16
