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 response, we conclude that the most natural reading of limitation [l] results from examination of the entire limitation: “locating encryption information that identifies encrypted portions of frames of video within the requested portions of the selected stream of protected video.” Ex. 1001, 27:54–57. The “within” most naturally connotes where the encrypted portions of frames of video occur, as opposed to determining where the encryption information may be located. Patent Owner’s interpretation is not wrong, i.e., the limitation could be read as Patent Owner suggests, leading to a narrower construction, but we are not persuaded that the construction of limitation [l] must be so limited, on the basis of the words themselves. We continue to reject Patent Owner’s interpretation that limitation [l] requires locating encryption information within the requested portions of the selected stream of protected video. See Inst. Dec. 27–30; 1st Final Dec. 8. Although it is apparent that encryption information can be found within the requested portions, we are not persuaded that the claim language or ’588 Patent implicitly or explicitly requires such a relationship. Likewise, although embodiments disclosed in the Specification of the ’588 Patent are consistent with Patent Owner’s more restrictive construction, the Specification also is consistent with the more grammatically correct construction as well. Thus, we construe limitation [l] as requiring that the encrypted portions of frames of video be within the requested portions of the selected stream of protected video, but we do not construe limitation [l] as requiring that the encryption information be within the requested portions of the selected stream of protected video.” slip op. at 15

    “The District Court did not provide an element-by-element analysis of how the claims of the ‘856 Patent cover this description. See Ex. 1027, 41. However, from the description, we understand the Court to have concluded that the system receives rules, identifies a set of packets as part of a flow using the NetFlow logs, “determines” that encrypted packets in the flow match known malicious signatures based on unencrypted data in other packets (e.g., data in the SNI), and then filters the flow based in a URI (e.g., that from the SNI), routing it to the null interface. The Court does not describe how the system “determines” that encrypted packets match known malicious signatures based on information in unencrypted packets, but we assume that is done as in the ‘856 Patent, by correlation, i.e., an encrypted packet is “determined” to match a threat indicator if it is in the same flow as a packet with unencrypted information that matches the threat indicator.10 With that understanding, we conclude that the allegedly infringing system operates, as least at the level described in the court’s decision, in the same way Buruganahalli’s system operates, filtering encrypted packets due to their presence in a flow that includes packets with unencrypted data, such as in a handshaking packet. It follows that Patent Owner is unable to establish a nexus, because “[w]here the offered secondary consideration actually results from something other than what is both claimed and novel in the claim, there is no nexus to the merits of the claimed invention.” Novartis AG v.

    “This argument is unpersuasive because Buruganahalli uses rules/policies to filter encrypted packets by correlating them with handshaking packets that have unencrypted data, in the same way that is done in the ‘856 Patent. The only “filtering step” in the patent that “use[s] rules to filter encrypted packets without decryption” (PO Resp. 20) is the hello message approach used, for example, at steps 19 and 23 (see id.), which is clearly disclosed in Buruganahalli.7 As explained above, the ‘856 Patent does not describe applying rules to encrypted packets. Instead, it describes (a) filtering encrypted packets by correlating them with unencrypted data in other packets and (b) by decrypting the packets and applying the rules that are recited in the claims to unencrypted data. As also explained above, the amendment added the rules of step 22, which are applied to decrypted data, to a claim that was drafted to cover filtering of encrypted packets. However, among the criteria used in the filtering performed at step 22 is a “uniform resource identifier (URI),” which, we conclude, covers Buruganahalli’s “domain name.” Thus, despite the error made during prosecution, the claims that issued cover Buruganahalli’s method of determining that a session should be filtered based on a domain name in unencrypted handshake data.” slip op. at 28

The Court does not describe how the system “determines” that encrypted packets match known malicious signatures based on information in unencrypted packets, but we assume that is done as in the ‘856 Patent, by correlation, i.e., an encrypted packet is “determined” to match a threat indicator if it is in the same flow as a packet with unencrypted information that matches the threat indicator.10 With that understanding, we conclude that the allegedly infringing system operates, as least at the level described in the court’s decision, in the same way Buruganahalli’s system operates, filtering encrypted packets due to their presence in a flow that includes packets with unencrypted data, such as in a handshaking packet. It follows that Patent Owner is unable to establish a nexus, because “[w]here the offered secondary consideration actually results from something other than what is both claimed and novel in the claim, there is no nexus to the merits of the claimed invention.” Novartis AG v.

    “need and industry recognition for the technology claimed in the ‘856 Patent because it describes the problem of detecting threats in encrypted traffic as ‘unsolvable.’” PO Resp. 68 (citing Ex. 1027, 64). Given that this is a press release by a company announcing that company’s new commercial product, however, we 8 The concurrence reevaluates Patent Owner’s evidence of industry praise and nexus, but we deem such considerations outside the remit of the Federal Circuit’s remand. are reluctant to give the “unsolvable” characterization much weight, as it may amount to puffery. But beyond that, it appears that the problem identified as “unsolvable” in the press release––“detect[ing] known attack signatures even in encrypted traffic”––had, in fact, already been solved in Buruganahalli, using the very same hello message, flow correlation, and man-in-the-middle techniques described in the ‘856 Patent. We thus cannot say that the press release identifies a long-felt need that was actually unsolved. See ZUP, 896 F.3d at 1374 (explaining that “[w]here the differences between the prior art and the claimed invention are . . . minimal . . . it cannot be said that any long-felt need was unsolved”) (quoting Geo.

    “challenge fails even if Petitioner’s summary of the references were correct because Petitioner did not present a sufficient reason to modify Feldman to include a current zoom level in its search request. FWD 56. The Federal Circuit vacated this finding specifically and contemplated that there would be a “consideration of obviousness” on remand. CAFC Dec. 10–11. That consideration requires more than determining whether any one reference teaches a current zoom level and a search, generally. See FWD 56 (quoting MTA Reply 10). Here, Petitioner’s challenge is based on modifying the Feldman-Jackson combination. So the Board must determine on remand whether the Feldman-Jackson combination in view of knowledge of a POSA meets the claim limitations at issue. We also disagree to the extent that Petitioner argues that the Board is precluded from considering additional arguments on the relevant issues on remand. The Board’s preliminary guidance on the Motion to Amend stated that Petitioner’s obviousness rationale was based on convenience and this reason was not sufficiently supported: reference lacks a sufficient explanation of why one of ordinary skill in the art would have added the zoom levels in the prior art to Feldman. See id. At most, Petitioner argues that it would be convenient to “specify the area the user desires to search for content” in this way. Id. at 14. But, on this record, Petitioner has not sufficiently explained why it would be convenient to do so in Feldman. See id. Nor has Petitioner sufficiently explained how or why the prior-art features confer this convenience. See id. MTA PG, 13.

Petitioner additionally states that “[a]dditional graduate education could substitute for professional experience, or significant experience in the field could substitute for formal education.” Pet. 3. Patent Owner does not in its Response address the level of ordinary skill. Patent Owner’s expert witness, Dr. Cooklev, testifies that he “will apply the same definition of the level of skill of a POSITA [as Petitioner].” Ex. 2004 ¶ 19. Based on the evidence of record, we determine a person of ordinary skill would have had a bachelor’s degree in electrical engineering, computer engineering, computer science, or a related field, and two years of experience related to the design or development of wireless communication systems. This is consistent with Petitioner’s articulation of the level of ordinary skill, with the exception of Petitioner’s open-ended reference to “at least” two years of experience, because that would improperly encompass a level of experience only possessed by an expert.

    “Patent Owner contends: “The plain meaning of the claims requires that the same ‘plurality of antennas’ be used for transmitting and receiving the plurality of signal streams.” PO Resp. 5, 9–12. Citing Dr. Cooklev’s testimony, Patent Owner contends that the ’083 patent’s Specification describes embodiments that use the same antennas for both transmitting and receiving data streams.

In the Final Written Decision, we determined: Although we do not understand the claims to require both transmission and reception “via all antennas” all of the time, we determine the claims require a set of antennas in which at least some of the antennas are for both transmitting and receiving. We disagree with Petitioner that two separate sets of antennas— one set of transmitting antennas and a separate, nonoverlapping set of receiving antennas—fall within the scope of the challenged claims.

    “legally sufficient motivation for modifying Paulraj, but only attempted to show that the modification “could” have been made by one of ordinary skill in the art which is not enough for a showing of obviousness. Sur-reply 8–9. We disagree with Patent Owner. Establishing that certain technique was well-known to one of ordinary skill in the art at the effective filing date of the challenged patent constitutes sufficient motivation to make a modification in accordance with what was well-known in the art to one of ordinary skill, absent factors not present here. Indeed, “if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.” KSR, 550 U.S. at 417. That would be the situation where a technique was well-known to one of ordinary skill in the art, unless there is actual difficulty in making the application. The “improvement” here, although not articulated by Petitioner, is inherent with the technique, not requiring use of separate antennas for transmitting and receiving, i.e., eliminating the need for additional parts. Further, it is not necessary to show that a modification is the “best option,” because any “suitable option” would suffice. See Intel Corporation v. Qualcomm Incorporated, 21 F.4th 784, 800 (Fed. Cir. 2021). Here, Patent Owner does not assert that one of ordinary skill in the art would have had difficulty modifying Paulraj to use some of the same antennas both for transmitting and for receiving. Nor does Patent Owner dispute that it was well known to one of ordinary skill in the art to use the same antenna(s) for both transmitting and for receiving. We further note the following description in the Specification of the ’083 patent: “The typical CT/MD [cellular telephone/mobile device] has one transmitter and one receiver (T/R), with one antenna.” Ex. 1001, 1:47–48. That statement is fully consistent with Petitioner’s assertion that it was well-known to use the same antenna for transmitting and for receiving. For the foregoing reasons, notwithstanding Patent Owner’s arguments to the contrary, we determine that Petitioner sufficiently has shown that it would have been obvious to one of ordinary skill in the art to modify Paulraj such that some of the same antennas would be used both for transmitting and for receiving, according to limitations 1[b], 1[d], and 1[e].” slip op. at 36

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.
