9 v. ORDER GRANTING IN PART AND DENYING IN PART MOTION TO 10 PALO ALTO NETWORKS, INC., STRIKE INFRINGEMENT CONTENTIONS AND DENYING 11 Defendant. MOTIONS TO SEAL 12 Re: Dkt. No. 127, 128, 133, 138

13 14 Defendant Palo Alto Networks, Inc. has filed a motion to strike the infringement 15 contentions of plaintiff Finjan LLC. See Dkt. 128. The parties have also filed a total of 16 three motions to seal. See Dkt. 127, 133, 138. Having read the parties’ papers and 17 carefully considered their arguments and the relevant legal authority, and good cause 18 appearing, the court hereby rules as follows. 19 Motion to strike infringement contentions 20 Palo Alto Networks’ motion makes three arguments with respect to Finjan’s 21 infringement contentions: (1) the contentions do not contain sufficient detail to provide 22 notice of Finjan’s infringement theories, (2) the contentions do not contain pinpoint 23 citations to source code, and (3) the contentions make conclusory allegations with 24 respect to the doctrine of equivalents. Palo Alto Networks argues that the contentions 25 violate Patent Local Rule 3-1, which requires, among other things, a “chart identifying 26 specifically where and how each limitation of each asserted claim is found within each 27 accused instrumentality.” 1 an exemplar. The claim language discloses “a content processor (i) for processing 2 content received over a network, the content including a call to a first function, and the 3 call including an input, and (ii) for invoking a second function within the input, only if a 4 security computer indicates that such invocation is safe.” See Dkt. 128 at 6. 5 Palo Alto Networks argues that “Finjan offers no explanation of what a ‘first 6 function’ is” and “never identifies where a ‘second function’ is allegedly found in the 7 accused products.” Dkt. 128 at 6, 7. 8 In its opposition, Finjan effectively concedes that its contentions do not identify 9 these functions. Finjan instead blames the contentions’ lack of specificity on Palo Alto 10 Networks’ alleged failure to produce certain documents, arguing that “the information 11 PAN claims is missing is exactly the information PAN failed to make available to Finjan, 12 and Finjan made that clear in the contentions.” Dkt. 133-4 at 13. Finjan then cites the 13 contentions themselves, which state that the first function “varies in each instance 14 depending on the nature of the requested content, and is implemented by at least the 15 source code cited below and the SML files, which to date, PAN has not produced despite 16 repeated requests by Finjan.” Id. 17 In a footnote, Finjan explains that “PAN produced these [SML] files for inspection 18 only after Finjan served its contentions,” and that “they provide key information about the 19 identity of the ‘first functions’ and ‘second functions’ that PAN complains are missing in 20 the contentions.” Dkt. 133-4 at 13, n.3. Finjan then represents that “[o]nce Finjan has 21 had a chance to fully analyze the remaining unproduced source code and any 22 corresponding documentary descriptions (should PAN produce them), it fully intends to 23 supplement its contentions.” Id. 24 Another court in this district faced the same issue with respect to the same “first 25 function” and “second function” terms of the ’154 patent. See Finjan, Inc. v. Proofpoint, 26 Inc., 2015 WL 1517920 (N.D. Cal. Apr. 2, 2015). The Proofpoint court first explained that 27 “to satisfy Patent Local Rule 3-1(c) as to claim 1a, Finjan was required to identify what 1 In other words, what constitutes the ‘first function’ [and] ‘second function’ [] in the 2 allegedly infringing” products? Id. at *7. The Proofpoint court then concluded that 3 “[t]hese are questions that Finjan’s infringement contentions do not answer.” Id. 4 While the contentions in this case – unlike in Proofpoint – do use the terms “first 5 function” and “second function,” even Finjan acknowledges that the contentions are not 6 clear identifying those functions in the accused products. Dkt. 133-4 at 13. As 7 mentioned above, Finjan itself states in its brief that, after it served its contentions, it 8 received discovery containing “key information about the identity of” the “first function” 9 and “second function.” Id. at 13, n.3. Finjan further states that it received SML files 10 which are “relevant” and that it “plans to move to amend its contentions to incorporate 11 this additional evidence.” Id. at 10. 12 Finjan’s complaints about Palo Alto Networks’ discovery production appear similar 13 to its arguments in Finjan, Inc. v. Sophos, Inc., in which the court observed that:

14 The bulk of Finjan’s opposition brief is dedicated not to defending the 15 sufficiency of its infringement contentions but to explaining why various alleged deficiencies in [defendant’s] source code production have 16 prevented it from making its contentions better. Finjan does not go so far as to concede that its contentions are inadequate, but its focus in its briefing 17 is on blaming [defendant] for whatever inadequacies exist. 18 2015 WL 5012679 at *1 (N.D. Cal. Aug. 24, 2015)). 19 In Sophos, the court ultimately concluded that “[i]t is not clear which party (if either) 20 is at fault for the current state of Finjan’s infringement contentions,” “[b]ut it is clear that 21 Finjan is willing to amend them.” 2015 WL 5012679 at *1. The court reaches a similar 22 conclusion in this case. Though it is not entirely clear whether Finjan or Palo Alto 23 Networks (or both) are to blame for the current dispute, Finjan has implicitly 24 acknowledged that its contentions are not entirely clear regarding at least the “first 25 function” and “second function” claim limitations. And as discussed above, Finjan has 26 indicated its intention to “move to amend its contentions to incorporate [] additional 27 evidence.” Dkt. 133-4 at 10. 1 infringement contentions on the grounds that they do not adequately identify where and 2 how each of the claim limitations, including the “first function” and “second function,” can 3 be found in the accused products, the motion is GRANTED in part. Palo Alto Networks’ 4 motion appears to seek that the contentions be stricken with prejudice, but as in Sophos, 5 the court gives Finjan 30 days to serve amended infringement contentions in accordance 6 with this order. See also Proofpoint, 2015 WL 1517920 at *12 (“Where appropriate, the 7 court will treat a motion to strike as a motion to compel amendment.”). The amended 8 contentions shall not add any products, technologies, or claims, or expand the scope of 9 its infringement theories. 10 As a separate matter, the court notes that Finjan repeatedly cites to the sheer 11 number of pages in its contentions as evidence that the contentions provide sufficient 12 detail. See, e.g., Dkt. 133-4 at 1 (“serving infringement contentions that total over 2,100 13 pages”), 2 (“The contentions comprise ten claim charts, total 2,141 pages”). The court is 14 not persuaded by Finjan’s argument that, because the infringement contentions are over 15 2,000 pages, they must be sufficiently detailed. If anything, any focus on the length of 16 the contentions is a distraction from the real issue – the substantive content of the 17 contentions. Moreover, rather than file over 2,000 pages of exhibits, which the court 18 neither has the time nor the inclination to read, the parties are directed to streamline their 19 future filings for the purpose of judicial economy. 20 Argument (2) in Palo Alto Networks’ motion is that Finjan’s contentions are 21 deficient because they do not contain pinpoint citations to source code. The Proofpoint 22 court also addressed this issue.
