      “B. LEVEL OF ORDINARY SKILL IN THE ART In determining the level of ordinary skill in the art, various non- exhaustive factors may be considered, including: “(1) the educational level of the inventor; (2) type of problems encountered in the art; (3) prior art solutions to those problems; (4) rapidity with which innovations are made; (5) sophistication of the technology; and (6) educational level of active workers in the field.” Daiichi Sankyo Co. v. Apotex, Inc., 501 F.3d 1254, F.2d 693, 696 (Fed. Cir. 1983). Petitioner contends that a person of ordinary skill in the art at the time of the invention (“POSITA,” “PHOSITA,” or “skilled artisan”) “would have the equivalent of an undergraduate degree in computer science, engineering, operations research, or similar discipline, along with one year of experience in computer programming” and that “[t]he more education one has, the less experience needed to attain an ordinary level of skill[, and] . . ., more experience in the field may serve as a substitute for formal education.” Pet. 9 (citing Ex. 1003 ¶ 32).

      “We generally agree with Petitioner that the assumptions and approximations made in the calculations described in the ’397 patent to determine the external surface area of the components of the litter render the computations only a general approximation of the respective surface areas. See Pet. Reply 9–12. We need not, however, reach the issue of whether the 47% surface area limitation requires the use of the multi-step method disclosed in the ’397 patent because Petitioner followed that methodology in its arguments and evidence in its Reply. See Pet. Reply 13. Importantly, Patent Owner agrees that Petitioner followed the approach set forth in the ’397 patent, and argues that we need not construe “external surface area” to resolve any dispute between the parties.

      “review of the record, we find that Petitioner fails to articulate an adequate rationale for the combination of Goss and House. The Petition contains only a single sentence addressing the issue, without any citation to record evidence or declaration support. See Pet. 46. In addition, the assertion merely states the conclusion that a “PHOSITA would understand that there is a rational underpinning to combine the teachings of Goss and House as required under patent law because both are related to cat litter having similar characteristics.” Id. This assertion, at most, addresses the fact that Goss and House are in the same field or that they are analogous art, but does not explain why a PHOSITA would have been motivated to combine Goss and House. See id. In addition, the Petition lacks sufficient explanation of how Petitioner proposes to combine Goss and House. See Pet. 46–53. Instead, when Petitioner relies on House in this challenge, it appears to be a back-up argument in the event that we find Goss fails to disclose the limitation. Merely stating that Goss and House both disclose a limitation does not explain which aspects of House Petitioner proposes adding to Goss or what the resulting litter composition would look like. See id. The details of the resulting litter based on the combination of Goss and House matter here because it could impact whether all limitations of a given claim are satisfied by the combination. For example, Petitioner relies exclusively on specific examples from Goss for the 47% surface area limitation, but adding some aspects of House’s litter components to meet other limitations could undermine Petitioner’s reliance on Goss’s specific examples. The failure of the Petition to set forth a specific combination elides these issues. See Pet. 46–51. Petitioner’s Reply arguably addresses some of these concerns by providing a more fulsome motivation section, backed by new expert testimony, and specific litter examples based on Goss and various cellulose filler materials allegedly disclosed by House. See Pet. Reply 24–25 (citing Ex. 1013 ¶ 7); see also PO Sur-reply 18–22 (arguing that Petitioner’s Reply still fails to articulate an adequate motivation to combine). This analysis goes far beyond the limited analysis in the Petition, and Petitioner provides no reason why it could not have been included in the Petition. See Pet. Reply 24–25.

      “Patent Owner makes a number of arguments, but we do not find them persuasive enough to undermine Petitioner’s showing based on Ms. Borgese’s analysis. Patent Owner’s primary argument stems from its assertion that the bulk densities vary depending on a number of variables and that Ms. Borgese bases her ranges on documents, the technical data sheets for FS-40 and the ’397 patent for BL(2), that have bulk densities that are not the “same” as the bulk densities for FS-40 and BL(2) in Goss due to the passage of time, differences in where the clay was mined, how the clay was processed, and how the bulk density was measured. See PO Resp. 18– 19, 21–33; PO Sur-reply 2, 5–9. We do not view Petitioner’s challenge as based on the premise that the FS-40 clay referenced in the technical data sheets and Blue Mountain clay in the ’397 patent are the exact same as the FS-40 and BL(2) clays in Goss, but instead the clays and their bulk densities are similar enough that they will fall within the bulk density ranges Petitioner uses in its calculations. See Pet. 21–23, 68; Pet. Reply 6–7, 10. As a result, Patent Owner’s repeated assertions that the clays or their properties are not the “same” or processed “exactly the same” fail to engage 5 Patent Owner suggests that Petitioner fails to meet the inherency standard because Ms. Borgese uses the term “potential” when describing the bulk density range of BL(2). See PO Resp. 32 (citing Ex. 1003 ¶ 117). We do not read Ms. Borgese’s opinion in the same manner. Instead, we read the reference to “the potential bulk density range of BL(2), 35–47 lbs/ft3” as referring to any bulk density within that range, not that there is only the mere potential that the bulk density may fall within that range. See Ex. 1003 ¶ 117. Petitioner’s argument that the bulk densities were at least similar, such that that they fall within the ranges Petitioner uses. See, e.g., PO Resp. 4, 21–24, 30–31; Ex. 2009 ¶¶ 97–98 (Dr. Johnston limiting opinion to whether the clays are the “same”). As an example, when asked about the potential differences in bulk density between Goss’s filing date in 1997 and the 1999 technical data sheet, Ms. Borgese states that “[b]entonite clays have not changed significantly in a period of two years.” Ex. 2008, 24:7–15; see also Ex. 1003 ¶¶ 202–203 (opining that “modest difference in particle-size distribution between FS-40 disclosed in Goss [and] . . . the FS-40 Information Sheet ’99 only minimally impacts the bulk density”). Given Ms. Borgese’s personal experience making animal litters and using bentonites, we view her testimony as credible absent some evidence that any differences in bulk density would fall outside the ranges she uses. Patent Owner provides no such evidence. Nearly all of Patent Owner’s evidence goes to whether the clays and bulk densities would be the exactly the “same” in Goss as in the sources that Ms. Borgese relies on, and do not address how similar the bulk densities would be and do not attempt to establish that there are bulk densities for Goss’s FS- 40 and BL(2) clays that would fall outside the ranges Ms. Borgese uses. In the rare instances where Patent Owner does argue that the bulk densities would not be similar, or would not fall within Dr. Borgese’s ranges, Patent Owner fails to cite any evidence to support the assertion.

Pet. 4–5; PO Resp. 14. That definition presumes “experience in animal litter process development” and “familiarity with the composition and chemistry of various clays used in animal litter (including sodium bentonite).” Pet. 4–5. We find Ms. Borgese’s education and first-hand experience in animal litter process development, including experience with bentonite, sufficient to testify credibly as to the known bulk densities of the bentonite clays at issue in the case. As to Goss’s FS-40 sodium bentonite clay made by Wyo-Ben, Ms. Borgese opines that the range of bulk density for the material in Goss is between 58–64 lb/ft3 based on Wyo-Ben’s own technical data sheets from 1999 and 2002, which “describe the same (or similar) FS-40 (‘sodium bentonite’) composition.” Ex. 1003 ¶¶ 82–83, 106, 117; Pet. 21–22, 35. Then, in an effort “to be conservative in [her] analysis,” Ms. Borgese uses a broader range of 55–65 lb/ft3 for Goss’s FS-40 in her calculations. Ex. 1003 ¶ 117. Even when pushing her assumptions in directions that would result in the lowest possible external surface area percent for sodium bentonite, all of the calculations across the full range of potential bulk densities still meet the 47% surface area limitation. Id. ¶¶ 117–122; Pet. 43–46. Based on our review of the arguments and evidence, we find Ms. Borgese’s testimony as to the range of Goss’s FS-40 bulk density credible and persuasive.” slip op. at 25

In addition, Patent Owner fails to cite any authority that permits what amounts to a motion to exclude within the confines of the merits briefing, which forced Petitioner to devote space in its merits brief to opposing the motion to exclude. See id.; Pet. Reply 19–23. Under these circumstances, we deny the motion as procedurally improper. In addition, even if we reached the merits, we would not exclude the documents or Ms. Borgese’s opinions based on them given that she reasonably relied on the technical data sheets as reliable sources of bulk density data provided by Wyo-Ben, the manufacturer of the clays in question.

Petitioner further asserts that, although the Specification of the ’840 patent does not expressly define EFL, “its meaning is well known in the art, as exemplified in Li ([Ex.] 1007), which states that ‘[t]he focal length of a lens assembly [is] also referred to as the effective focal length[.]’” Pet. 8–9 (quoting Ex. 1007, 2:59–61) (alterations in the original). Patent Owner “does not believe that any terms require construction to resolve the disputes addressed in this response.” PO Resp. 3.

      “(2) Discussion of Rationale for Combining We have reviewed the record developed at trial including the cited portions of Parulski, Huang, and Tang. We determine that Petitioner has supported its seven reasons for combining Parulski, Huang, and Tang with sufficient rational underpinning evidenced by the exhibits cited above. Patent Owner does not dispute Petitioner’s rationale for combining. See generally PO Resp. We determine that Petitioner has shown that an ordinarily skilled artisan would have been motivated to combine Parulski, Huang, and Tang, and that such motivation is supported by sufficient rational underpinning.

      “As discussed above, we agree with Petitioner that Kirchhoff discloses the use of SSL, a protocol that uses data encryption (Ex. 1005, 8:47–49). We also agree with Petitioner that Krtolica discloses the use of HTTP protocols on port 80 (Ex. 1004, 6:23–24), and does so with a goal of maintaining high network security (id. at 1:7–10, 2:33–36). As Kirchhoff discloses, and Dr. Lavian’s testimony supports, one of ordinary skill in the art would have been aware that port 443, rather than port 80, would be used for secure web connections using SSL, which includes the use of encryption, and this would have resulted in enhanced network security. See Ex. 1005, 3:38–41; Ex. 1002 ¶¶ 52, 69, 108. As Dr. Lavian testifies, SSL/TLS was the most widely deployed security protocol in the world and the well-known use of SSL in HTTPS protocol enables secure web-based e-commerce. Ex. 1002 ¶¶ 69, 108; Ex. 1035 ¶ 8; Ex. 1006, 5. And, Krtolica has a stated goal to maintain network security. Ex. 1004, 1:7–10, 2:33–37. We find this evidence provides a sufficient rational underpinning in support of obviousness for combining the teachings of Krtolica and Kirchhoff. See KSR, 550 U.S. at 418. Owner’s arguments that use of encryption in SSL was optional and adding encryption would allegedly undermine network security. Nor do we find persuasive the argument that the Petitioner’s motivation to combine based on efficiency is insufficient, because Petitioner relies on another rationale for the combination of Krtolica and Kirchhoff, that is, enhanced network security, also discussed above. We additionally do not find persuasive Patent Owner’s arguments that combining Krtolica and Kirchhoff would render the system of Krtolica unsatisfactory for its intended purpose because, as Petitioner argues, this assertion is contradicted by the state of the art at the time. See Pet. Reply 9. As discussed above, Dr. Lavian explains that there were known systems having firewalls with SSL traversal at the time of the invention. Ex. 1002 ¶¶ 53, 59–65; Ex. 1035 ¶ 20; Ex. 1014. Moreover, the ’978 patent uses encryption with firewalls using a single-port protocol, and Patent Owner does not direct us to any disclosure in that patent that indicates that the use of encryption with a single-port protocol was inventive in that the system, or that encryption had to be done in a special manner. See Pet. Reply 3 (citing Ex. 1001, Fig. 3 (at 311, 341), Fig. 5 (503, 508)); see also Ex. 1001, 6:4–8. In a similar vein, Patent Owner argues that due to incompatibilities the combination of SSL with Krtolica would be unsuccessful, and we address this issue below.” slip op. at 30

      “Where the prior art contains “apparently conflicting” teachings (i.e., where some references teach the combination and others teach away from it) each reference must be considered “for its power to suggest solutions to an artisan of ordinary skill . . . consider[ing] the degree to which one reference might accurately discredit another.” In re Young, 927 F.2d 588, 591 (Fed. Cir. 1991). In Hosner, AES encryption appears to have one of the higher processing speeds of the algorithms tested. See Ex. 1006, 23. Further, the ’978 patent itself supports the acceptable performance of AES encryption in single-port protocol, stating that “[a]ny method or algorithm of encryption may be used” with its invention “including, but not limited to 128-bit find Patent Owner’s argument on the use of AES to be persuasive. We have reviewed Petitioner’s explanations and supporting evidence as to how the combination of Kirchhoff and Krtolica teach the limitations of claims 4, 16, and 24, and we agree with and adopt Petitioner’s analysis.
