“First, we find that Becton, Dickinson factor (c)––the extent to which the asserted art was evaluated during examination––does not favor denying the petition under Section 325(d) because the Examiner did not cite Behbahani or Tan in any rejection and did not specifically address either reference in any correspondence, other than initialing them in an IDS. For factors (e) and (f), we find that Petitioner has explained sufficiently how the Examiner allegedly erred in evaluating Behbahani and Tan, by pointing to the Proposed Grounds, which detail how the challenged claims read on these references. See Pet. 17–67. We find this sufficient to identify the “specific teachings” that were overlooked, as contemplated in Advanced Bionics, and we agree with Petitioner that the facts and discussion of Behbahani or Tan presented in the Petition warrant reconsideration of the challenged claims in view of those references. We thus find that Petitioner has satisfied step 2 of the Advanced Bionics framework by demonstrating that the Examiner may have erred by not appreciating that Behbahani and Tan teach or suggest the features of the claimed invention. For these reasons, we decline to exercise our discretion to deny institution under 35 U.S.C. § 325(d).” slip op. at 12

“Based on the present record, we find Petitioner’s rationale sufficient for institution. Petitioner points to Krantz’s alleged goals of security and automation. Pet. 19. Petitioner (id.) and Dr. Houh (Ex. 1503 ¶ 64) both cite paragraph 19 of Krantz, which states that “[i]f credentials do not authorize full access . . . the server can respond by sending a notification . . . includ[ing] conditions (e.g., signup, renewal etc.) a user must satisfy to become authorized for []full access to resources.” Ex. 1505 ¶ 19.

See, e.g., Ex. 1503 ¶ 64; Ex. 1506 ¶ 68. Krantz’s express teaching of conditions for a client to fully access a network (Ex. 1505 ¶ 19) also undermines Patent Owner’s argument about impermissible hindsight and Patent Owner’s suggestion that Krantz is limited to user authentication. Finally, we are persuaded that Petitioner has shown sufficiently, for purposes of instituting review, that an ordinarily skilled artisan would have expected success in making the combination because it would only require software modifications to Krantz’s system.

Petitioner disagrees that the present record sufficiently shows that the inventors of the ’450 patent conceived of the invention before the effective date of Krantz or Herrmann and that the inventors exercised reasonably continuous diligence in reducing that invention to practice. See Prelim. Reply 1–7. In particular, Petitioner raises questions with respect to the independence of Patent Owner’s evidence from the inventor testimony that evidence is intended to corroborate, as well as with respect to whether the evidence offered by Patent Owner sufficiently shows conception, reduction to practice, and reasonably continuous diligence. Id. We do not think the information of record is sufficient to antedate Krantz and Herrmann such that we should deny institution of inter partes review on that basis. First, Patent Owner’s arguments rely on the testimony of inventor Stacey C. Lum, who has not yet been subject to cross-examination. See Prelim. Resp. 35–45 (citing Ex. 2003). Second, Petitioner identifies several issues where further development of the record may be helpful. For example, Patent Owner’s asserted date of conception is associated with the date of an engineering specification included in the record as Exhibit 2011. See Prelim. Resp. 35–36 (citing Ex. 2003 ¶ 12; Ex. 2011; Ex. 2012). We agree with Petitioner (see Prelim.

The specification supports this understanding. “When a receiver is actively receiving a desired signal, each block in the signal path has at its input the desired signal as well as noise and possibly interfering signals.” Ex. 1001, 5:20–22; see also id. at 5:31–33 (“FIGS. 2A and 2B illustrate examples of desired signals, interferers, and noise that may be received by one of the various circuits in a” slip op. at 21

“We agree with Patent Owner that Rauhala does not state that the signal strengths are measured simultaneously or at the same time. Indeed, as discussed above, Rauhala indicates unequivocally in the same paragraph the opposite—that detector DET provides to control unit 42 “an indication about either the receive channel signal strength RSS or the strength of any signal on the reception band.” Ex. 1004 ¶ 17. Rauhala describes that “control unit 42 provides two one-bit control signals cA and cM” based on indications received from detector DET. Id. Importantly, Rauhala indicates that “at the same time as” describes how the control unit 42 uses the received inputs RSS and RSSn shown in Figure 4, which are described earlier in paragraph 17 as indications of either RSS or RSSn from detector DET.

The burden remains on Petitioner to demonstrate by a preponderance of the evidence that Rauhala discloses the disputed limitations as arranged or combined in the claim. Petitioner does not persuasively reconcile these “either/or” statements regarding the functioning of detector DET with the “at the same time as” statements regarding control signals output by control unit 42 in paragraph 17. We do not find persuasive Petitioner counsel’s position expressed at the hearing that Rauhala’s “either/or” statements are “simply an imprecise description” (Tr. 16:22–24).

“Petitioner argues that “a [person of ordinary skill in the art] would find the challenged claims unpatentable under any interpretation consistent with their plain and ordinary meaning in the context of the [’645 patent],” so we “need not expressly construe the claim terms.” Pet. 8. Patent Owner also argues that we should apply the plain and ordinary meaning of all claim terms. Prelim. Resp. 6. Nonetheless, Patent Owner argues that Petitioner deviates from the plain and ordinary meaning of certain limitations. Id. at 6– 7. Thus, Patent Owner puts forth its understanding of the plain and ordinary meaning for the following recitations: “configure an access point in response to approval of the device by the gatekeeper” and “device information received from the device in response to the audit request.” Id. at 7–13.

- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner
“Based on the present record, we find Petitioner’s rationale sufficient for institution. Petitioner points to Krantz’s alleged goals of security and automation. Pet. 19. Petitioner (id.) and Dr. Houh (Ex. 1203 ¶ 64) both cite paragraph 19 of Krantz, which states that “[i]f credentials do not authorize full access . . . the server can respond by sending a notification . . . includ[ing] conditions (e.g., signup, renewal etc.) a user must satisfy to become authorized for []full access to resources.” Ex. 1205 ¶ 19. We are persuaded preliminarily that an ordinarily skilled artisan considering Krantz’s teachings of such conditions for full access would have had reason to apply Herrmann’s technique for checking a client’s antivirus security policy in the manner suggested by Petitioner. See, e.g., Ex. 1203 ¶ 64; Ex. 1206 ¶ 68. Krantz’s express teaching of conditions for a client to fully access a network (Ex. 1205 ¶ 19) also undermines Patent Owner’s argument about impermissible hindsight and Patent Owner’s suggestion that Krantz is limited to user authentication. Finally, we are persuaded that an ordinarily skilled artisan would have expected success in making the combination because it would only require software modifications to Krantz’s system. See, e.g., Ex. 1203 ¶¶ 65, 93.” slip op. at 26

“Petitioner argues that “a [person of ordinary skill in the art] would find the challenged claims unpatentable under any interpretation consistent with their plain and ordinary meaning in the context of the [’350 patent],” so we “need not expressly construe the claim terms.” Pet. 7.

Resp. 7–9. Patent Owner also argues that we should construe the phrases “audit data pertaining to a device” and “auditing the device in accordance with a security policy” as “requir[ing] that the ‘audit data’ and ‘auditing’ . . . be expressly about the device” rather that “the user.” Id. at 9–12.

“We agree with Patent Owner. The ’350 patent distinguishes between user authentication using a username and password and application of a security policy. Ex. 1101, 1:35–39 (“A first level of access control is achieved by requiring authentication of a user. This may be accomplished by requiring the user to enter a username and a password.”), 1:45–48 (“Reliance on mere user authentication includes several disadvantages. For example, there are no provisions to assure that an access device used by the authenticated user meets network security policies.”). Although the ’350 patent describes both user authentication and application of a security policy as being carried out by a gatekeeper, this is accomplished in separate process steps. Id. at 10:38–41 (“GateKeeper 225 authenticates a user, obtains audit data, and applies a security policy in an Authenticate User Step 440, an Obtain Audit Data Step 450 and an Apply Security Policy Step 460, respectively.”). Thus, we are not persuaded that, as Petitioner argues, user authentication in the ’350 patent constitutes the application of a security policy.” slip op. at 12

“Petitioner, supported by Dr. Staniford’s testimony, proposes that a person of ordinary skill in the art at the time of the invention “would have had a bachelor’s degree in computer science, computer engineering, or an equivalent, and four years of industry experience,” and “would have had a working knowledge of packet-switched networking, firewalls, security policies, communication protocols and layers, and the use of customized rules to address cyber-attacks.” Pet. 16 (citing Ex. 1003 ¶¶ 23, 25). Patent Owner does not challenge the qualifications proposed by Petitioner for a person of ordinary skill in the art. See generally PO Resp.

“We largely agree with Patent Owner that there is no explicit claim- construction dispute. We address Patent Owner’s issues of what ordinarily skilled artisans would have considered in creating and implementing packetfiltering rules in the discussion below. The preservation of the flow of normal legitimate network traffic without disruption is one aspect that those with a working knowledge of packet-switched networking, firewalls, security policies, communication protocols and layers, and the use of customized rules to address cyber-attacks would have considered. Nonetheless, overall, we determine that the plain and ordinary meaning of “configured to prevent an exfiltration operation,” does not require preventing all exfiltrations from occurring, nor allowing all non-exfiltration traffic, and that we need not consider the preservation of the flow of normal legitimate network traffic without disruption in the context of that claim construction.
