      “Federal Circuit. The court issued its decision in Medivis, Inc. v. Novarad Corp., No. 2024-1794, 2026 WL 587294 (Fed. Cir. Mar. 3, 2026) (“Medivis”) (Paper 40),1 affirming-in-part, reversing-in-part, and remanding our Final Written Decision (Paper 35) for further proceedings. 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.

      “in these respects. The preambles of claims 17 and 59 recite the “audio device wearable by a user for storing locally generated audio.” There is neither mention of “multi-track” audio in the claim, nor is the audio device limited to capturing a single source of sound, such as a single performer. Accordingly, we are not persuaded that the ’443 and ’207 patent claims support the limited scope that Patent Owner urges for the term “locally generated audio.” None of Patent Owner’s citations to the specification define or require that the “locally generated audio” correspond to audio generated only by a single performer. See, e.g., 230 IPR, Ex. 1001, 8:59−62 (stating that the local audio input device “may be worn by the performer and connects to local audio device 102 at local audio input device port 314”). Patent Owner’s argument that the specification “teaches a single creator/performer per local audio device” is well-taken, but the teachings do not indicate the intent to exclude other sounds from being captured at the local audio device (or indicate how the device would prevent the capture of other sounds, such that the audio would be “isolated” as Patent Owner contends). See 230 Sur-Reply 10 (citing 230 IPR, Ex. 1001, 4:28−32, 10:29−34, and Insituform Techs., Inc. v. Cat Contr., Inc., 99 F.3d 1098, 1105 (Fed. Cir. 1996) (“[C]laim 1 refers to ‘a cup’ and ‘the cup’ repeatedly, suggesting that only one cup is involved . . . . [N]either the specification nor the drawings disclose the use of more than one cup.”)). For instance, the specification describes that the “independent track of audio is received from one of the performer’s local audio device 102.” 230 IPR, Ex. 1001, 10:33−34. Thus, in this description the audio track corresponds to the audio captured by a particular audio device—which was worn by the performer— but does not limit that captured audio to only sounds made by the performer. As to the “local audio data” term, Patent Owner argues that “audio data” means “mono or stereo audio files created from independent, isolated locally generated audio files, such files suitable for creation of a multi-track audio file.” 230 PO Resp. 9−10 (citing Ex. 2140 ¶¶ 131, 134). This argument is unsupported by the claim language or specification. The claim does not require the creation of audio files, much less a “multi-track audio file.” The specification describes storing audio files in memory without the specificity that Patent Owner urges we adopt. See 230 IPR, Ex. 1001, 13:1−14. Accordingly, we are not persuaded by Patent Owner’s proposed construction of “local audio data.” Rather, we understand “audio data” to have a plain and ordinary meaning, such as the one given to the term by the District Court in the underlying litigation. 230 IPR, Ex. 1037, 10. We adopt the District Court’s construction of “audio data” to mean “data comprising audio signals in digital form.” Id. This finds support in the specification as the audio is described as being converted into digital audio and stored in a file. See 230 IPR, Ex. 1001, 13:1−14. Our conclusion is consistent with the plain and ordinary meaning of the term as that would be understood by a person of ordinary skill in the art, and we see no reason to deviate from the conclusions of the District Court on this point.” slip op. at 20

    • Expert testimonySkill level petitioner adoptedOther

      “E. Level of Ordinary Skill in the Art Based on the argument and evidence presented in the Petition and Patent Owner’s preliminary response, we determined, as stated in our Decision on Institution, that “a person of ordinary skill in the art would have had a Bachelor’s degree in electrical engineering and two or more years of experience working with audio and wireless communications systems.” 230 Dec. on Inst. 16; 232 Dec. on Inst. 22−23. Patent Owner reiterates its position that a person of ordinary skill the art would have had “a bachelor’s degree in electrical engineering or a related subject and two to five years’ experience working with multi-track audio and wireless communications systems in the professional performance industry.” 230 IPR, PO Resp. 6−7 (emphasis added) (identical passage in 232 PO Resp. 8). Thus, the dispute centers on whether the level or ordinary skill includes specific work experience with multi-track audio in the professional performance industry. We do not agree that this specific work experience is necessary to the level of ordinary skill in the instant proceedings. In determining whether an invention would have been obvious at the time it was made, we consider the level of ordinary skill in the pertinent art at the time of the invention. Graham v. John Deere, 383 U.S. 1, 17−18 (1966). “The importance of resolving the level of ordinary skill in the art lies in the necessity of maintaining objectivity in the obviousness inquiry.” Ryko Mfg. Co. v. Nu‑Star, Inc., 950 F.2d 714, 718 (Fed. Cir. 1991). The “person of ordinary skill in the art” is a hypothetical construct, from whose vantage point obviousness is assessed. In re Rouffet, 149 F.3d 1350, 1357 (Fed. Cir. 1998). In determining the level or ordinary skill, we may consider various factors including “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC, 57 F.3d 1573, 1579, (Fed. Cir. 1995) (quoting Custom Accessories, Inc. v. Jeffrey-Allan Indus., Inc., 807 F.2d 955, 962 (Fed. Cir. 1986)). Patent Owner’s proposed specificity of work with multi-track audio in a professional performance industry is not supported by the record. First, Patent Owner submits conclusory declaration testimony of James DeFilippis—repeating verbatim, and without any supported reasoning, Patent Owner’s proposed level of ordinary skill.

This sentence does not cure the deficiency noted above regarding Petitioner’s reliance on Ahn’s graphic shadow moving with a gesture. Chaudhri is relied on for the proposition that, Ahn’s graphic shadow is “[i]ndeed” a movable image known to give a user a visual cue. Id. But no such “cue” is provided in Ahn by the graphical shadow alone, because there is no movement of that object.

      “the theory that Ahn’s graphic shadow moves. Reply 3−4. Petitioner interprets the sentences in Ahn we have analyzed above in conjunction with testimony of Dr. Terveen to argue that temporal descriptions in Ahn make it obvious for a person of ordinary skill in the art to drag in the right direction while continuing to press the graphic 1800. Id. (citing Exs. 1004 ¶¶ 117−119, Ex. 1023 ¶ 10). The Petition, however, relies on an Ahn disclosing a moving graphic shadow according to the embodiment of Figure 18(a), as described in paragraph 118. Petitioner now changes its theory of how Ahn’s graphic shadow would move according to paragraph 119, i.e., that although the graphic shadow is merely pressed (in the embodiment shown in Figure 18(b)) it would also be dragged while pressed. Reply 3. Not only is this a shift from the theory Petitioner presents in the Petition, it is not persuasive. As Patent Owner argues, and we agree, there is no cogent explanation for modifying the graphic shadow embodiment of Figure 18(b), especially in light of Ahn’s disclosure that the graphic shadow disappears when pressed and the menu list is displayed as emerging. Sur-reply 2−3. In other words, Petitioner’s new argument does not account for Ahn’s teaching that the objective of the graphic shadow is merely to notify the user of the start of the gesture, and once that start of the gesture is detected (the press on the graphic shadow), paragraph 119 informs us that there is no longer a need for the graphic shadow—it disappears from the display. Ex. 1004 ¶ 119. The Petition does not offer any argument for a theory in which the gesture of paragraph 119 (the press, not a touch and drag operation) results in graphic 1800 disappearing, while also moving during the disappearance. We are mindful that “[i]t is impermissible within the framework of section 103 to pick and choose from any one reference only so much of it as will support a given position to the exclusion of other parts necessary to the full appreciation of what such reference fairly suggests to one skilled in the art.” Bausch & Lomb, Inc. v. Barnes-Hind / Hydrocurve, Inc., 796 F.2d 443, 448 (Fed. Cir. 1986)). Consequently, we determine that Petitioner’s argument in Reply belatedly relying on the different embodiment of paragraph 119 is improper new argument, and that even if considered it is not persuasive.” slip op. at 20

We adopt Petitioner’s characterization because it is consistent with the level of skill in the art at the time of the invention as reflected by the ’402 patent and the cited prior art. See Okajima v.

      “specification explicitly includes sensors similar to those in the prior art in support of their argument that the claimed “predetermined cycle” must not exclude the use of such sensors. Pet. Reply 15 (citing Ex. 1001, 32:55–33:7, 40:66–41:5, 44:9–29). We reviewed the portions of the specification cited by Petitioner. We agree with Patent Owner that one excerpt discussing sensor use appears to be directed to triggering the predetermined cycle rather than causing timing changes during the cycle itself (Ex. 1001, 32:55–66) (describing use of a pressure sensor to “determine when the vacuum channel 3 is clogged by a thrombus and automatically perform the unclogging procedures described herein”), while another excerpt discusses a sensor that Petitioner that the ’402 patent discusses the use of sensors to “tune” the system and that such “tuning” can be done statically (setting the cycle timing in advance) or dynamically (adjusting the timing during the cycle itself). See Ex. 1001, 48:19–49:50. Overall, we find that these disclosures involving sensors demonstrate that sensors may be used in various ways in different embodiments. However, none of these disclosures explicitly discuss the use of sensors in conjunction with a “pre-determined cycle.” Therefore, we find that the ’402 patent specification’s discussion of “sensors” are not particularly informative as to the appropriate construction of a “predetermined cycle” and do not outweigh the other explicit disclosures of “predetermined cycle” in the patent. We next turn to the other intrinsic evidence discussed by the parties — the prosecution history. As discussed by Patent Owner, in the Notice of Allowance, the Examiner found that Garrison did not teach or suggest a “predetermined cycle” because Garrison’s controller “changed the cycle of opening and closing the valves based on feedback from sensors.” Ex. 1004, 86. We acknowledge that the patent applicant filed subsequent comments during prosecution in which they stated that they “do[] not concede that the Examiner’s characterizations of the terms of the claims and the prior art are correct.” Id. at 29. However, we agree with Patent Owner that the importance of the Examiner’s statement in the Notice of Allowance does not rely on it being an express disclaimer (a standard which it does not meet). PO Sur-reply 8. We also considered Petitioner’s contention that the Examiner’s interpretation of Garrison may have been in error (PO Resp. 16); however, even if this were true, the Examiner’s statement still provides helpful insight into how the Examiner was interpreting the term sensors to change the opening and closing of valves during a cycle was not a “predetermined cycle.” Id. at 86. In sum, we find that Patent Owner’s proposed construction is consistent with the usage of the term “predetermined cycle” in the ’402 patent specification and prosecution history. Thus, after considering all of the cited evidence, we construe “predetermined cycle” to mean that “the timing of the sequence of valve operations in the cycle is determined beforehand, i.e., fixed, rather than varying based on feedback after operation begins.”” slip op. at 14

      “2. Other Terms The parties also provided proposed constructions for the limitations of “[limited/limiting] to a positive amount of exit flow” and “control[ling] fluid flow in and out from the distal end of the catheter.” See Pet. 15–16; Pet. Reply 1–8; PO Resp. 22–24; PO Sur-Reply 2–6. However, having evaluated the arguments and evidence before us, we determine that construction of these terms is not necessary for purposes of this Decision. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (citing Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed.

      “We agree with Patent Owner that neither Petitioner nor Mr. Brown propose any combination of Yang and Mullins that does not include Mullins’s pressure sensor in order “to control fluid flow in and out from the distal end of the catheter.” Indeed, in addressing the “predetermined cycle” limitation, Mr. Brown contends that Mullins discloses a “cycling controller that ‘varies aspiration pressure according to sensed pressure within the catheter lumen.’” Ex.1005 ¶¶ 131–32 (citing, e.g., Ex.1008, 27:40–28:20 (“[a] novel aspect of this pump system is the incorporation of feedback into the pump algorithm in order to produce more effective pressure cycling”)). This use of a sensor to change pressure during a cycle, is not a “predetermined cycle” under our construction. combinations is its discussion of distal end flow control, not for its sensors.” Pet. Reply 17 (citing Ex. 1035 ¶ 83). However, Petitioner’s obviousness grounds rely on the combination of Yang and Mullins, especially with regard to Mullins’s disclosure of “a controller” in order “to control fluid flow in and out.” As discussed above, Mullins relies on the sensor-feedback approach in order to control flow and we find that Petitioner has not presented persuasive evidence of how the combined disclosures of Yang and Mullins would control flow without using Mullins’s sensor feedback approach. See W.L. Gore & Assocs., Inc. v. Garlock, Inc., 721 F.2d 1540, 1550 (Fed. Cir. 1983) (error to “consider[] … references in less than their entireties, i.e., in disregarding disclosures in [them] … that diverge from and teach away from the invention”). Therefore, we determine that Petitioner has not sufficiently shown that the combination of Yang and Mullins discloses or renders obvious “a controller configured to open and close the vacuum valve and the vent valve in a predetermined cycle to change a level of vacuum at the distal end of the catheter and to control fluid flow in and out from the distal end of the catheter.” Accordingly, having considered the parties’ respective evidence and arguments, we find that Petitioner has not shown by a preponderance of the evidence that claim 1 of the ’402 patent would have been unpatentable as obvious over the combination of Yang and Mullins.” slip op. at 27

      “rather than the combination of Ingle’s capacitor and Hasei’s droplet discharge application that Petitioner asserts. See In re Keller, 642 F.2d 413, 426 (CCPA 1981). Even if Ingle falls short of teaching structured application for its capacitor’s cathode, as Patent Owner argues, that does not undermine Petitioner’s challenge because Petitioner proposes using Hasei’s structured application (i.e., a droplet discharge device) to form the cathode of Ingle’s capacitor. See Pet. 24–25. Patent Owner’s additional argument that “Hasei contains no discussion of forming capacitors” (PO Resp. 36; see PO Sur-reply 17–18) is similarly flawed—it attacks Hasei individually, while ignoring Ingle’s capacitor teaching. We agree with Petitioner—the combination of Ingle and Hasei teaches structured application of the capacitor’s cathode. In addition, we disagree with Patent Owner that “Petitioner provides no reason why a POSITA would have extended Hasei’s method for producing its OLED to a capacitor.” PO Resp. 36; see PO Sur-reply 17 (asserting “pure conjecture”). To the contrary, as noted above, Petitioner explains, with relevant support from Hasei, that its structured application method reduced electrode-material waste and shortened manufacturing times as compared to photolithography. Pet. 25 (citing Ex. 1007 ¶¶ 5, 7). Given those benefits, Petitioner has articulated sufficient reasoning with rational underpinning to support that its proffered combination would have been obvious.

      “obviousness of the menus in the Ahn-Chaudhri combination following a user’s finger as the user performs the dragging gesture to open the menu.” Pet. Reply 2 (citing 01119-Petition, 26–33, substantially identical to Pet. 32– 40). However, again, the Petition does not explain an alternative theory in which Chaudhri supplements Ahn’s menu functionality to move that menu onto the screen, as opposed to teaching visual cues provided by gradual changes of the display during a gesture or the visual cue that an unlock image may provide during the unlock gesture. See Pet. 14–18 (describing Chaudhri teaching “visual differentiation” or “transitioning an optical intensity” between a user-interface object and the background, based on, e.g., transparency), 35–40 (same). In Reply, Petitioner adds evidence to attempt to support its contention that the combination teaches a menu following a user’s finger during a dragging gesture, involving references to Chaudhri’s discussion of a visual cue, further discussing Chaudhri’s unlock image. Ex. 1005 ¶¶ 54, 62, 74–79, Figs. 5A-5C (cited at Pet. Reply 4–5). With respect to these citations and arguments, even if they had been timely presented in the Petition, we agree with Patent Owner that they do not articulate a modification of Ahn with Chaudhri or a motivation to combine. PO Sur-reply 6. Additionally, we agree that these embodiments of Chaudhri are distinct from the cited portions of Chaudhri discussed with respect to this theory in the Petition, which relate not to the movement of displayed graphics, but to variations of optical intensity and visual cues. Id. at 6–7. We evaluate the Petition’s arguments in light of Petitioner’s statement in Reply that they require a teaching regarding “menus . . . following a user’s finger as the user performs the dragging gesture.” Pet. Reply 2. To the extent that the Petition shows that the combination of Ahn and Chaudhri would show visual changes as the user performs a dragging gesture, these do not relate to the movement of a menu, but rather to other optical effects. Thus, as we do not find that the Petition supports an Ahn-Chaudhri combination in which a menu follows a user’s finger as the user performs the dragging gesture to open the menu, as Petitioner argues, we determine that Petitioner has not shown limitation 2.d of claim 2 taught or suggested by the combination of Ahn and Chaudhri according to this theory.” slip op. at 31

      “Petitioner argues that “even under [this] interpretation of Ahn, the only difference between Ahn and the claims is whether the animation occurs in direct correspondence with a user’s dragging gesture or after the dragging gesture is complete – a straightforward design choice if ever there was one.” Pet. Reply 3–4 (citing Ex. 1024, 99:16–108:20; Ex. 1023 ¶ 12). However, as Patent Owner argues (PO Sur-reply 7–8) this argument is presented in Reply and is an improper shift of theory from the Petition. Nevertheless, were we to consider it, we would not find it compelling; Dr. Terveen’s cited testimony repeats this bare statement and is not supported by any evidence or additional explanation.
