    “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.

Patent Owner also challenges motivation to combine Suzuki because it “is not directed to a pay-by-time, pay-per-view, or subscription distribution model, in which a content key grants access to content that different clients must individually decide to purchase in discrete units or increments.” Id. at 36–37.

    “We agree with Petitioner that the substitute claims are broadening. Because the amended wording only requires the key request to be made “in response to detecting” the boundary, rather than “ahead of” the boundary, the request can occur before or after the boundary. This is not a fanciful or unlikely possibility — such delayed requests are specifically contemplated by the ’178 patent: [I]f the packager 104 is unable to obtain a new content encryption key from the WFM 102 prior to the expiration of the current content encryption key, the packager 104 will continue to use the current content encryption key until such time as it is able to obtain a new key from the WFM 102.

    “Petitioner argues that Limitations 8B and 12B are directed to the configuration or structure of the bowl fill valve outlet port. Pet. Reply 2–4. According to Petitioner, because Limitations 8B and 12B do recite an overflow tube, the overflow tube is not separately claimed and is recited solely to define the function of the outlet port on the bowl fill valve. Id. at 3. Petitioner, thus, argues that an overflow tube is not separately claimed as a structural element, and that, to meet Limitations 8B and 12B, it is sufficient to show that the prior art discloses a bowl fill valve with an outlet port that is configured to attach directly to a tube that provides water from the outlet port to an overflow tube. Id. at 4. In contrast, Patent Owner argues that Limitations 8B and 12B separately claim the overflow tube, and that Petitioner must show that the prior art discloses a tube that transfers water from the bowl fill valve outlet port to the toilet tank overflow tube. PO Resp. 10–11; PO Sur-reply 2–3. We disagree with Patent Owner, because claims 8 and 12, on their face, require “bowl fill valve outlet port,” but do not require or recite an “overflow tube” as an element of the claimed “bowl fill valve.” When a structure is claimed as “configured to” perform a particular function, it generally requires a structure that is designed to perform the particular function claimed, i.e., it requires more than the mere capability of performing that function. See Aspex Eyewear, Inc. v. Marchon Eyewear, Inc., 672 F.3d 1335, 1349 (Fed. Cir. 2012) (claim language including the phrase “adapted to” is to be construed consistent with “configured to” language and requires that the structure must be “designed or configured to accomplish the specified objective, not simply that [it] can be made to serve that purpose.”); see also In re Giannelli, 739 F.3d 1375, 1379 (Fed. Cir. 2014). The plain language of Limitations 8B and 12B is clearly directed to the configuration of the bowl fill valve outlet port, in that these limitations recite “a bowl fill valve outlet port configured to.”8 The recited function is “attach directly to a tube that provides water from the bowl fill valve outlet port to an overflow tube.” The overflow tube is recited as part of the function in a clause identifying the tube to which the bowl fill valve outlet port is configured to attached — “that provides water from the bowl fill valve outlet port to an overflow tube.” The overflow tube, thus, is recited as part of the function defining the required structure of the bowl fill outlet port and is not separately claimed.” slip op. at 16

By virtue of the manual setting of handle 119 of the bowl fill valve 109, the flow of water through the bowl fill valve 109 is regulated. In this manner, the flow of water is regulated so that enough water flows out of the bowl fill valve 109 to fill a toilet bowl without wasting any water down a drain. seen from the passage above, the ’606 Application discloses regulating an amount of water supplied to a toilet bowl using a valve (i.e., a water flow regulator).

Patent Owner’s witness, Dr. Papanikolopoulos, does not provide an explanation for his opinion or support his definition of the level of ordinary skill with citations to evidence. See Ex. 2023 ¶ 57 (“In my opinion, [Petitioner’s definition] is an excessive level of ordinary skill in the art, and I believe instead [an ordinarily skilled artisan] would more likely have two years of experience rather than four years.”). On the other hand, Petitioner’s witness, Dr. Thorpe, does provide an explanation for his opinion, explaining that his assertion that four years of experience is required is based on the state of the art, typical undergraduate curricula, and his supervision of doctoral students. Ex. 1030 ¶ 21. Based on the arguments presented and the cited references, we find Petitioner’s definition of the level of ordinary skill reasonable and for purposes of this Decision, adopt it as our own.

    “As a general rule, unless the steps of a method claim actually recite an order, the steps are not ordinarily construed to require one.” Mformation Techs., Inc. v. Rsch. in Motion Ltd., 764 F.3d 1392, 1398 (Fed. Cir. 2014) (citation modified). “However, a claim requires an ordering of steps when the claim language, as a matter of logic or grammar, requires that the steps be performed in the order written, or the specification directly or implicitly requires an order of steps.” Id. (cleaned up). “[O]rdinarily in process claims steps taken concurrently are the equivalent of steps taken successively.” In re White, 39 F.2d 974, 975 (CCPA 1930); see also Cybersettle, 243 F. App’x. at 609 (finding “the step of calculating the differences between demands and offers can occur concurrently with the [next enumerated step of] receipt of multiple demands and offers” and “the testing step of ‘determining whether any of the differences fall within the predetermined settlement range’ may occur concurrently with the receipt and comparison of the bids” (citation modified)). This is especially true here, given that the recitations at issue are functional language in an apparatus (system) claim. We further agree with Petitioner that the ’328 patent discloses such concurrent performance of these steps: Either concurrent with or subsequent to the identification of road signs 30 and generation of asset management database 24, the computer processor 22 evaluates that portion 32 of each video frame or image that depicts a road sign 30 to determine a set of color values 40, 42 for each of a plurality of colors on the road sign 32. A retroreflectivity value is generated for each color portion 34, 36 on each frame of the tagged videostream 20 containing the road sign 30 that represents a different color value 40, 42. slip op. at 13

    “Petitioner is correct to the extent that it need not show that “the features of [Schofield] may be bodily incorporated into the structure of [Gallagher],” but Petitioner must prove that “a skilled artisan would have been motivated to combine the teachings of the prior art references to achieve the claimed invention.” Allied Erecting, 825 F.3d at 1381. For claim 9, Petitioner proposes to modify Gallagher’s system to use “Schofield’s determination of a light source’s location within a field of view” in Gallagher’s system. Pet. 23. Thus, Petitioner’s combination does not require the combination of Gallagher’s and Schofield’s sensors into a single system, and Patent Owner’s “sensor fusion” argument is inapposite. See Tr. 48:8–49:6 (Patent Owner’s counsel confirming that the problem of “sensor fusion” stems from combining disparate sensors in a single system). As noted above, Schofield teaches considering the relative location of the light source in determining whether the light source is from headlights or taillights (that is, an object of interest). See Ex. 1006, 9:26–35. We are persuaded that an ordinarily skilled artisan would be motivated to use this teaching in Gallagher’s device to help distinguish between road markers that are arranged side-by-side and have a reasonable expectation of success in doing so. See Ex. 1005 ¶ 40; Ex. 1003 ¶¶ 77 (“[An ordinarily skilled artisan] would have seen Schofield’s determination of a light source’s location within the field of view as advantageous because it would have allowed Gallagher’s computer to associate the measured reflectance level with the appropriate road marker.”), 79 (“[I]mplementing this determination would have required [an ordinarily skilled artisan] to implement only conventional techniques of image processing (identifying a location of a particular pixel within an array), which was well known by [an ordinarily skilled artisan], to predictably yield the result of the location within a field of view indicating an intensity value associated with a road marker. Given that Schofield and Gallagher disclose similar types of arrays, this combination would have merely required the use of Schofield’s known technique to improve Gallagher’s similar device in the same way.”).” slip op. at 30

    “A reference qualifies as prior art for a determination under § 103 when it is analogous to the claimed invention. In re Clay, 966 F.2d 656, 658 (Fed. Cir. 1992). Two separate tests define the scope of analogous prior art: (1) whether the art is from the same field of endeavor, regardless of the problem addressed, and (2) if the reference is not within the field of the inventor’s endeavor, whether the reference still is reasonably pertinent to the particular problem with which the inventor is involved. In re Bigio, 381 F.3d 1320, 1325 (Fed. Cir. 2004) (citing In re Deminski, 796 F.2d 436, 442 (Fed. Cir. 1986)).” slip op. at 49
