      “evidence does not establish WD4 was indexed in a manner that one ordinarily skilled in the art, exercising reasonable diligence, could locate it. See Response 45. There is no evidence that the JCT-VC site provided users sufficient guidance on finding documents of interest. Importantly, there is no evidence that one could search for or locate WD4 based on its subject matter. Although the Torino document register contains the number, title, and source (i.e, authors’ names) of each document, the subject of the document is not listed or identified. See In re Cronyn, 890 F.2d 1158, 1160– 61 (Fed. Cir. 1989) (finding references were not publicly accessible, despite the use of indexing, because the references were indexed only by title and author’s name, rather than by subject). Furthermore, identifying a meeting location was key to navigating the JCT-VC site; however, there is no evidence showing that persons of skill in the art outside of JCT-VC would have had any knowledge or familiarity with the cities in which the JCT-VC meetings were conducted or that the names of the cities were helpful in any respect in locating a document on the site. For these reasons, the evidence does not support the conclusion by a preponderance of the evidence that persons interested and ordinarily skilled in the art at the time of the invention would have been aware of the JCT-VC document repository site, or that, if they were aware of the site, would have been able to locate the WD4 document relied upon by Samsung.” slip op. at 19

      “Mr. Bross’s testimony is conclusory and insufficiently factually supported. We understand Mr. Bross to be testifying in this regard as a fact witness pursuant to Federal Rule of Evidence 602, rather than as an expert witness pursuant to Federal Rule of Evidence 702. Under Rule 602, a fact witness may testify as to a matter only if “evidence is introduced sufficient to support a finding that the witness has personal knowledge of the matter.” Fed. R. Evid. 602. Here, Mr. Bross’s testimony is based on his “knowledge and recollection” and “the prominence of the JCT-VC” in the video coding industry. However, the particular factual knowledge on which the testimony is based is not described. Similarly, the “prominence” of the JCT-VC is nothing more than an unsupported assumption. We also find Mr. Bross has not been shown to have the requisite personal knowledge to testify about persons “who would regularly visit the JCT-VC site.” Even if we accepted Mr. Bross’s premise of the “prominence of the JCT-VC,” we would not find that to be a sufficient basis for Mr. Bross to reliably testify about persons “regularly visit[ing]” the JCT-VC site.” slip op. at 16

      “Although the Federal Circuit has endorsed application of the broadest reasonable interpretation in construing claims during postgrant proceedings before the Board, it has cautioned that such endorsement “is not to say, however, that the Board may construe claims during IPR so broadly that its constructions are unreasonable under general claim construction principles.” Microsoft Corp. v. Proxyconn, Inc., 789 F.3d 1292, 1298 (Fed. Cir. 2015). “Rather, ‘claims should always be read in light of the specification and teachings in the underlying patent.’” Id. (quoting Suitco Surface, Inc., 603 F.3d 1255, 1260 (Fed. Cir. 2010)). In addition, “[t]he PTO should also consult the patent’s prosecution history in proceedings in which the patent has been brought back to the agency for a second review.” Id. (citing Tempo Lighting Inc. v. Tivoli LLC, 742 F.3d 973, 978 (Fed. Cir. 2014)). The Federal Circuit has emphasized that, even under the broadest reasonable interpretation, “the Board’s construction ‘cannot be divorced from the specification and record evidence,’” id. (quoting In re NTP, Inc., 654 F.3d 1279, 1288 (Fed. Cir. 2011)), and “‘must be consistent with the one that those skilled in the art would reach,’” Id. (quoting In re Cortright, 165 F.3d 1353, 1358 (Fed. Cir. 1999)). With these principles in mind, we determine that Patent Owner’s proposed construction conforms with the broadest reasonable interpretation of “header field,” which excludes the “routing parameters” that are saved in the “routing table.” At the oral hearing, Patent Owner conceded that “if you look at the term header field in a vacuum without any context, it could mean” slip op. at 14

    • Obviousness (§103) › Graham factors (scope of art, differences, level of skill)Not shown unpatentableNot shown unpatentable

      “unpatentability, we determine that there are multiple deficiencies with Petitioner’s showing with respect to the proposed combination as related to specifically recited claim limitations. See 35 U.S.C. § 316(e); 35 U.S.C. § 312(a) (requiring the petition to identify “in writing and with particularity . . . the grounds on which the challenge to each claim is based”); see also 37 C.F.R. § 42.104(b) (requiring “a statement of the precise relief request”). Because we find that even the combination, if effected in the manner proposed by Petitioner, does not meet all limitations recited in the challenged claims, we do not reach the issue of whether Petitioner articulates sufficient reasoning with rational underpinning to effect the combination. See Pet. 21–28; PO Resp. 21–47. First, we agree with Patent Owner that Petitioner insufficiently shows that the combination it proposes teaches or suggests “using the routing channel number as an index to select the destination point to which the 7 Although we rely on illustrations of Petitioner’s proposed combination as set forth in the Reply because they are more clear, we find those illustrations consistent with the position taken by Petitioner in the Petition. See Pet. 24– 27. controller subsequently sends the data.” PO Resp. 59–61. This limitation is recited in both independent claims 1 and 12 in the context of searching for a destination point of the data in the routing table. Ex. 1001, col. 19, ll. 6–9, col. 20, ll. 40–43. In articulating how it draws a correspondence between elements recited in the claims and entries of its proposed routing table, Petitioner makes the following identifications: (1) the recited “routing channel number” corresponds to the channel identifier in the inbound VCI allocated to a first data path defined by the card access module and router; (2) the recited “source point” corresponds to “an identifier of the SAP associated with a smart card application on the contact smart card . . . in the inbound ‘VPI’; and (3) the recited “destination point” corresponds to “an identifier of an SAP associated with software . . . in the outbound VPI.” Pet. 36. With these correspondences, we agree with Patent Owner that the channel identifier in the inbound VCI cannot function as an “index to select the destination point” as the claims require because there is no unique association of the outbound VPI with the inbound VCI.8 PO Resp. 59. This is evident from the table provided in the Reply, and reproduced above, in 8 Although we agree with Petitioner, as explained above in Section II.C.3, that a construction of “routing table” does not require a “one-to-one correspondence between the routing channel number and each corresponding routing parameter,” see PO Resp. 57 (emphasis added), the nature of an “index” nevertheless requires a unique association of the index with what it indexes. That is, an “index to select the destination point” must uniquely identify the selected destination point, even if the same destination point can be selected by multiple indexes. A “one-to-one” correspondence would additionally require that each destination point be selected only by a single index. which the same VCIin value of “Chin 1” is associated with different values of VPIout, namely “CPU SAP 1” in the first row and “RF SAP 1” in the third row.” slip op. at 29

      “Petitioner also contends that “even under [Patent Owner’s] improper interpretation, it would have been an obvious implementation choice to use unique channel numbers as discussed in §V.B [of the Reply], such that the destination point is selected only with the channel number.” Reply 27–28 (citing Ex. 1024 ¶ 123). We do not consider this argument because it goes beyond the scope of argument made in the Petition. Intelligent Bio-Systems, Inc. v. Illumina Cambridge Ltd., 821 F.3d 1359, 1369 (Fed.

      “Although a claim term that does not include the word “means” is presumed not to invoke a means-plus-function analysis, that presumption may be overcome if the limitation does not “recite sufficiently definite structure” or recites a “function without reciting sufficient structure for performing that function.” Williamson v.

Because the ’703 patent has a filing date before September 16, 2012 (effective date of § 4(c)), we refer to the pre-AIA version of § 112. 1339, 1349 (Fed. Cir. 2015). Petitioner’s expert, Russell J. Hamilton, Ph.D., testifies that “the term ‘logic’ would not be recognized by one of ordinary skill in the art as providing sufficiently definite structure for performing the claimed functions,” and that “[l]ogic can be implemented in software, in hardware, and in combinations of hardware and software.” Ex. 1021 ¶ 122.

      “untenable because its broad identification only of “computer software and/or computer hardware” as structure for performing the recited function is too generic. The law regarding construction of means-plus-function limitations as applied to computer-implemented elements is well-established: For computer-implemented means-plus-function claims where the disclosed structure is a computer programmed to implement an algorithm, “the disclosed structure is not the general purpose computer, but rather the special purpose computer programmed to perform the disclosed algorithm.” . . .

Finisar Corp. v. DirecTV Group, Inc., 523 F.3d 1323, 1340 (Fed. Cir. 2008) (citations omitted). Patent Owner’s proposed construction is superior because it identifies the algorithm through explicit reference to the flow chart of Figure 4 and related disclosure in the Specification. Patent Owner’s position is supported by testimony of its expert, Sasa Mutic, Ph.D., who refers to those disclosures in opining that “the [’703] patent describes a process of steps for obtaining the result of properly positioning a patient to begin a treatment” and that “Fig. 4 of the [’703] patent provides a flowchart of a process for use of an embodiment of the invention.” Ex. 2012 ¶ 69. Petitioner takes the position that the ultimate scope of the corresponding algorithm “does not matter” because Petitioner contends that the challenged claims are unpatentable even under Patent Owner’s proposed construction. Pet. Reply 315, 3. Nevertheless, Petitioner attacks Patent Owner’s proposed construction as “implicitly adopt[ing]” two “additional but unreasonable limitations.” Id. First, Petitioner contends that “the claims do not require the performance of the function of the second logic to be fully automated and instead permit human interaction with the second logic.” Id. Second, Petitioner contends that blocks 520 (“Position Patient”), 525 (“Register Treatment Image Data with Simulator/Reference Image Data and Reposition Patient”), and 530 (“Position Clinical Treatment Machine”) of Figure 4 “need not be performed in their entirety by logic so long as the second logic is used for some step in each block.” Id. at 4. We find no inconsistency in these positions with Patent Owner’s proposed construction. In light of the foregoing considerations, we adopt Patent Owner’s proposed construction.” slip op. at 14

The script language virus detection methodologies may be performed periodically (e.g., once/twice per day) or at selected times (e.g., each time the computer is powered up or restarted) by the computer on all relevant electronic files.

      “The dispositive issue is whether Petitioner demonstrates, by a preponderance of the evidence, that the combination of Chandnani and Kolawa teaches or suggests “dynamically building” a parse tree “while” receiving an incoming stream of program code. Although the specific language differs in immaterial respects by reciting or omitting the structural elements of a “computer” or a “receiver,” such a limitation appears in each of independent claims 1, 9, 22, 23, 29, and 35 through a combination of recitations that include receipt of the incoming stream of programming code and “dynamically building” the parse tree “while” receiving the incoming stream. Petitioner contends that all limitations of independent claims 1, 9, 22, 23, 29, and 35 are taught by Chandnani “except for the use of a parse tree to store and analyze programming code,” and that “[i]t would have been obvious to combine Chandnani’s scanner with the parse-tree teachings of Kolawa” to meet the full set of limitations of each independent claim. Pet. 2001, 19–20. Although the parties agree that Chandnani describes lexical analysis of a “data stream” to generate a stream of tokens, they disagree whether Chandnani discloses that such lexical analysis occurs while receiving the incoming data stream, as recited in each of the independent claims.

      “At the oral hearing, we expressed surprise that a party would seek to exclude the cross-examination testimony of its own expert witness. See Tr. 49:19–52:8. Patent Owner’s counsel explained that it “provided a motion to exclude based on the way that the evidence was used in the reply.” Tr. 50:1–6. But the Board has previously explained that “neither a motion to strike nor a motion to exclude is a proper mechanism to present argument that a reply contains new arguments.” Ultratec, Inc. v. Sorenson Communications, Inc., Case IPR2013-00288, Paper 38 at 2 (PTAB May 23, 2014).

See 37 C.F.R. §§ 42.23, 42.65. We, therefore, consider Patent Owner’s arguments as going to the weight that should be given to the cross-examination testimony and related deposition exhibit, not to the admissibility of that evidence.

Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
