`
`Patent Owner, Finjan, Inc. (“Finjan” or “Patent Owner”), respectfully
`
`requests rehearing of the Board’s Decision on Institution (IPR2015-02001, Paper
`
`No. 7; IPR2016-00157, Paper No. 10) (the “Consolidated Institution Decision”)
`
`under 37 C.F.R. § 42.71(d). In particular, Finjan respectfully requests
`
`reconsideration of the decision to institute trial on the four grounds identified in the
`
`Consolidated Institution Decision.
`
`I.
`
`INTRODUCTION
`
`The Board applies an abuse of discretion standard when rehearing a decision
`
`on institution. “An abuse of discretion occurs where the decision is based on an
`
`erroneous interpretation of the law, on factual findings that are not supported by
`
`substantial evidence, or represents an unreasonable judgment in weighing relevant
`
`factors.” Star Fruits S.N.C. v. U.S., 393 F.3d 1277, 1281 (Fed. Cir. 2005) (citation
`
`omitted). Here, the Board should grant Patent Owner’s Request for Rehearing of
`
`the Institution Decision because the Board’s decision to institute trial with respect
`
`to Chandnani and Kolawa (and Chandnani and Kolawa further in view of Walls
`
`and/or Huang) rely on factual findings that are not supported by substantial
`
`evidence.

`
`II. THE BOARD OVERLOOKED PATENT OWNER’S SUBSTANTIVE ARGUMENTS
`REGARDING CHANDNANI’S FAILURE TO DISCLOSE “DYNAMICALLY
`DETECTING…”
`
`The Institution Decision should be modified because it relies “on factual
`
`findings that are not supported by substantial evidence.” Star Fruits, 393 F.3d at
`
`1281. In particular, the Board overlooked Patent Owner’s argument that
`
`Chandnani does not disclose the “dynamically detecting…” feature of the
`
`challenged claims at least because Chandnani “discloses a sequential, disjointed
`
`process for tokenizing a data stream and processing the tokens.” See IPR2016-
`
`00157, Paper No. 9 (“‘157 POPR”) at 29; see also IPR2015-02001, Paper No. 6
`
`(“‘2001 POPR”) at 19–20 and 30 n.6. In its Consolidated Institution Decision, the
`
`Board indicated that it adopted Petitioner’s fatally flawed argument because
`
`“Patent Owner’s counterargument relies on its position that Chandnani fails to
`
`disclose receipt of an incoming stream that is scanned.” See Institution Decision at
`
`18. However, this analysis does not address Patent Owner’s substantive arguments
`
`regarding the clear deficiencies of Chandnani presented in the ‘157 and ‘2001
`
`POPRs:
`
`In fact, Chandnani’s lexical analyzer (notably, tokenizer is not
`mentioned anywhere in the reference) does not operate ‘continuously
`and simultaneously,’ but rather discloses a sequential, disjointed
`process for tokenizing a data stream and processing the tokens. Once
`the data stream is generated on the computer, Chandnani discloses
`
`2
`
`
`
`Patent Owner’s Partial Request for Rehearing
`IPR2015-02001 & IPR2016-00157 (U.S. Patent No. 8,225,408)
`
`performing a two stage process for detecting viruses that first
`‘tokenize[s] the data stream’ and then ‘process[es] the tokens
`using the detection data.’ Id. at 7:56–59. Notably, as a result of
`this two-stage process, the processing of the tokens does not occur
`until after the data stream is fully tokenized. Id; see also id. at
`8:50–53 (‘If the check [to be performed] is a pattern match, the token
`stream is analyzed lexically using the pattern match detection
`data….’).
`
`‘157 POPR at 29; see also ‘2001 POPR at 19–20 and 30 n.6 (emphasis added).
`
`These arguments, which were explicitly presented in the POPRs, and which were
`
`not addressed by the Petition or the Board, fully rebut the unsupported argument
`
`presented in the Petitions upon which the Board relied in its decisions to institute
`
`trial in the instant cases—namely, that Chandnani’s tokenizer and analyzer
`
`“continuously and simultaneously operate on the incoming data stream.” ‘2001
`
`Petition at 33–34; see also Consolidated Institution Decision at 18.
`
`Accordingly, Patent Owner respectfully submits that the Board overlooked
`
`the argument the Chandnani in view of Kolawa fails to disclose “dynamically
`
`detecting, by the computer while said dynamically building builds the parse tree,
`
`combinations of nodes in the parse tree which are indicators of potential exploits,
`
`based on the analyzer rules.” As argued in the ‘2001 and ‘157 POPRs, rather than
`
`teaching an analyzer that “continuously and simultaneously operates on the
`
`incoming data stream” as Petitioner misleadingly argues, Chandnani discloses a
`
`3
`
`
`
`Patent Owner’s Partial Request for Rehearing
`IPR2015-02001 & IPR2016-00157 (U.S. Patent No. 8,225,408)
`
`two-stage process in which “the processing of the tokens does not occur until after
`
`the data stream is fully tokenized.” ‘157 POPR at 29; see also ‘2001 POPR at 19–
`
`20.
`
`Accordingly, Patent Owner respectfully requests that the Board modify its
`
`Consolidated Institution Decision to institute trial on the ‘408 Patent at least
`
`because Chandnani does not teach the “dynamically detecting” limitations of the
`
`challenged claims, as affirmatively demonstrated in Patent Owner’s POPRs.
`
`III. THE BOARD OVERLOOKED PATENT OWNER’S ARGUMENTS REGARDING
`WALLS’ FAILURE TO DISCLOSE “DYNAMICALLY DETECTING…”
`
`In addition, the Board failed to provide any analysis of Walls, leaving Patent
`
`Owner to guess at the reasons that trial was instituted. Specifically, Grounds 2 and
`
`4 of the Board’s Consolidated Institution Decisions rely on a proposed
`
`combination of Walls with Chandnani and Kolawa. As the Board acknowledges,
`
`Petitioner proposed the addition of Walls to the combination of Chandnani and
`
`Kolawa as “an alternative ground for finding that two limitations—the
`
`‘dynamically building’ and ‘dynamically detecting’ elements common to every
`
`Petitioned Claim—would have been obvious.” Consolidated Institution Decision
`
`at 21. However, the Board overlooked Patent Owner’s arguments regarding this
`
`“alternative” invalidity theory, which demonstrate that Walls does not teach the
`
`two features for which it was explicitly cited. See ‘157 POPR at 35–39; see also
`
`‘2001 POPR at 32–35.

`
`
`
`Patent Owner’s Partial Request for Rehearing
`IPR2015-02001 & IPR2016-00157 (U.S. Patent No. 8,225,408)
`
`Rather than providing any analysis, the Board only states that “[i]n view of
`
`our determination that Petitioner demonstrates a reasonable likelihood of
`
`prevailing on the basis of the Chandnani-Kolawa combination, it follows that we
`
`find Patent Owner’s arguments as to asserted deficiencies in that combination
`
`unpersuasive.” Consolidated Institution Decision at 22. Given this reasoning,
`
`Patent Owner is at a loss to understand the grounds of unpatentability that are at
`
`issue in this inter partes review proceeding. If the Board intends to rely solely on
`
`Chandnani and Kolawa, the grounds that add Walls are redundant because Walls
`
`adds nothing to the underlying combination. If the Board intends to give full
`
`consideration to the combination of Chandnani, Kolawa, and Walls proposed in the
`
`Petition, Patent Owner is entitled to have its pre-institution arguments regarding
`
`the deficiencies of Walls addressed by the Board, especially given that the
`
`arguments should significantly narrow the questions of patentability at issue in the
`
`current proceedings.
`
`In either case, in light of the Board’s decision to overlook Patent Owner’s
`
`dispositive arguments regarding Walls’ failure to disclose the claim limitations for
`
`which it was specifically cited, Patent Owner respectfully requests that the Board
`
`modify its Consolidated Institution Decision to remove Grounds 2 and 4 from trial.

`
`IV. CONCLUSION
`
`For at least the foregoing reasons, Finjan respectfully submits that the Board
`
`overlooked or misapprehended the arguments presented in the POPR that
`
`demonstrate that Petitioner failed to meet its burden to show a reasonable
`
`likelihood of success on the sole instituted ground. Finjan requests, therefore, that
`
`the Board modify its Institution Decision and decline to subject claims 1, 3–5, 9,
`
`12–16, 18, 19, 22, 23, 29, and 35 of the ‘408 Patent to inter partes review under
`
`35 U.S.C. § 103(a) in view of Chandnani, Kolawa, Walls, and Huang.
