“recent reading of the indicator stored in the memory during a period of a transmission interval in response to detecting a change in the sensed condition outside a predetermined range.” Ex. 1001, 14:63–67. This limitation also requires that “during the period of the transmission interval” the transmission “is suspended in response to detecting a change in the sensed condition within the predetermined range.” Id. at 14:67–15:4. Petitioner, therefore, must show that Kates-711 discloses a transceiver configured to transmit information or suspend transmission of the information during a “period” within a “transmission interval.” For the recited “transmission interval,” Petitioner contends that Kates’s “periodic intervals of ‘periodic monitoring’ is a [1.e] ‘transmission interval,’ during which there is a [1.e] ‘transmission period’ that includes a ‘report block.’” Pet. Reply 9. We agree with Petitioner for the following reasons. Kates describes the process shown in Figure 7 as follows: FIG. 7 is a flowchart showing one embodiment of operation of the sensor unit 102 wherein periodic monitoring is provided. In FIG. 7, a power up block 701 is followed by an initialization block 702, After initialization, the sensor unit 102 enters a low-power sleep mode. If a fault occurs during the sleep mode (e.g., the tamper sensor is activated), then the process enters a wake-up block 704 followed by a transmit fault block 705. If no fault occurs during the sleep period, then when the specified sleep period has expired, the process enters a block 706 where the sensor unit 102 takes a sensor reading from the sensor(s) 201. The sensor data is subsequently sent to the monitoring computer 13 in a report block 707. After reporting, the sensor unit 102 enters a listen block 708 where the sensor unit 102 listens for a relatively short period of time for instructions from monitoring computer 708. If an instruction is received, then the sensor unit 102 performs the instructions, otherwise, the process returns to the sleep block 703. Ex. 1004, 15:50–65. Based on this description of Figure 7, we find that Kates’s report block 707 corresponds to the recited “a period of the transmission interval” because it is a period of time when “sensor data is . . . sent to the monitoring computer.” Ex. 1004, 15:61. Further, block 707 is within an interval of “periodic monitoring” i.e., the process loop shown in Figure 7 beginning at block 703 and comprising steps 703, 706, 707, 708, 709, 710 and back to block 703. See also Ex. 1052 ¶ 22 (Dr. Neikirk testifying “each of [Kates’s] periodic intervals during which the ‘periodic monitoring’ process occurs is a ‘transmission interval’ . . . and the report block’ that occurs within this process is a transmission period.” (citations omitted)).” slip op. at 27

“We are persuaded that the combination of Drell and Knappe teaches limitation [1.1]. As described above, Petitioner provides extensive reasoning, supported by testimony from Dr. Houh, explaining how the combination of Drell and Knappe teaches limitation [1.1], and provides reasoning for why a person of ordinary skill in the art would combine the references. Patent Owner’s arguments largely do not address Petitioner’s contentions and fail to address Petitioner’s arguments in support of the combination. In addition, Petitioner supports its arguments with citations to the references and credible declarant testimony from the vantage of a person of ordinary skill in the art, while Patent Owner’s arguments as to the interpretation of the references and motivations (or lack thereof) of a person of ordinary skill in the art are insufficiently supported by testimony from the viewpoint of a person of ordinary skill in the art or citation to the references.10 See PO Resp. 16–18. We find Petitioner’s interpretation of the references and motivation to combine more persuasive than Patent Owner’s insufficiently supported attorney argument on these issues. Patent Owner also fails to explain how the alleged “fundamental” differences in Knappe and Drell have any bearing on how they are used in the proposed combination. See PO Resp. 16–18; Sur-reply 3–4. Rather, Patent Owner’s argument merely points out alleged differences between the references, while essentially ignoring their commonalities. To the extent Patent Owner is arguing that it would not have been obvious to physically combine Drell and Knappe or bodily incorporate them into each other,11 Petitioner states, with supporting testimony from Dr. Houh, that the 10 Although Patent Owner cites to paragraphs 21 and 22 of Mr. Dye’s Declaration (PO Resp. 17), this testimony does not support the arguments for which it is cited. In the Sur-reply, Patent Owner clarifies that the citation should have been to paragraph 20 of Mr. Dye’s Declaration (Sur-reply n. 1), but, as discussed below, this testimony merely repeats arguments made in the Sur-reply. See Sur-reply 4–5. 11 “The test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference . . . . Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art.” MCM Portfolio LLC v. Hewlett-Packard Co., 812 F.3d 1284, 1294 (Fed. Cir. 2015) (quoting In re Keller, 642 F.2d 413, 425 (CCPA 1981)). proposed combination “permits, but does not require, physical incorporation of elements from Drell and Knappe.” Pet. 22 (citing Ex. 1003 ¶ 168) (emphasis added). In the Sur-reply, Patent Owner further argues that “Drell and Knappe deal with traditional video conferencing and conferencing systems– dedicated circuit architecture using traditional hardware,” whereas “the ’525 patent is directed to ‘computer system architecture and more particularly to audio and video telecommunications for collaboration over hybrid networks.’” Sur-reply 4 (citing Ex. 1001, 1:17–20). To the extent that Patent Owner is arguing that Drell and Knappe are not analogous art to the ’525 patent, we do not find this persuasive. As Petitioner argues, both references pertain “to the field of multiparty conferencing, including mixing data from Internet and PSTN conference endpoints.” Pet. 17 (citing Ex. 1008, code (54), 3:33–37; Ex. 1006, 3:41–51, 6:59–62; Ex. 1003 ¶¶ 148–149). Patent Owner also argues12 that “[n]either Drell nor Knappe reflect or disclose an understanding of the requirements of the different mixers or would teach or suggest this to a person of skill in the art” (Sur-reply 4) but, aside from this conclusory statement, does not further address or explain why Petitioner’s contentions as to Drell or Knappe are incorrect. Although Patent Owner cites to paragraph 20 of Mr. Dye’s Declaration, this testimony merely repeats what is stated in the Sur-reply. In this instance, “the cited declaration testimony is conclusory and unsupported, adds little to the conclusory assertion for which it is offered to support, and is entitled to little weight.” Xerox Corp. v. Bytemark, Inc., IPR2022-00624, Paper 9 at 15 12 This is a new argument raised in the Sur-reply. However, even if we consider this argument, we do not find it persuasive for the reasons stated.

“In the Sur-reply, Patent Owner further argues that “Drell and Knappe deal with traditional video conferencing and conferencing systems– dedicated circuit architecture using traditional hardware,” whereas “the ’525 patent is directed to ‘computer system architecture and more particularly to audio and video telecommunications for collaboration over hybrid networks.’” Sur-reply 4 (citing Ex. 1001, 1:17–20). To the extent that Patent Owner is arguing that Drell and Knappe are not analogous art to the ’525 patent, we do not find this persuasive. As Petitioner argues, both references pertain “to the field of multiparty conferencing, including mixing data from Internet and PSTN conference endpoints.” Pet. 17 (citing Ex. 1008, code (54), 3:33–37; Ex. 1006, 3:41–51, 6:59–62; Ex. 1003 ¶¶ 148–149). Patent Owner also argues12 that “[n]either Drell nor Knappe reflect or disclose an understanding of the requirements of the different mixers or would teach or suggest this to a person of skill in the art” (Sur-reply 4) but, aside from this conclusory statement, does not further address or explain why Petitioner’s contentions as to Drell or Knappe are incorrect. Although Patent Owner cites to paragraph 20 of Mr. Dye’s Declaration, this testimony merely repeats what is stated in the Sur-reply.

As Petitioner’s description of a person of ordinary skill requires some level of education and experience with the subject matter of the ’997 patent and the references, Petitioner’s description appears more applicable to the issues before us.

As alluded to earlier on page 16 of the demonstratives, Sourcefire tells you what the intrusion rule is. It is a specified set of key words and arguments. It is not the rule header.

Graham v. John Deere Co., 383 U.S. 1, 17–18 (1966).

“Second, Patent Owner argues that the challenged claims require “the caching of entire packets, not just the relevant portion of every incoming packet.” PO Resp. 11 (citing Ex. 2005 ¶ 43). Patent Owner’s declarant states that “[a] POSITA would understand that because the term packet is used to describe both the unit of data received at the network device and the unit of data that is cached, the Challenged Claims require caching the entirety of the packet received at the network device, which generally includes both header and payload data.” Ex. 2005 ¶ 43 (citing Ex. 2008, 385). We generally agree with Patent Owner’s position, that one of ordinary skill in the art would consider that caching of a packet would include caching the entire packet. We also presume that the caching of only relevant portions of a packet could be construed as caching a packet in the context of monitoring packets passing through a network device, for example, but we are persuaded that the intent of the independent claims is to cache the packets that have yet to be processed when a swapping of rule sets has been instigated, such that those packets, i.e., entire packets, can be processed under the new rule set. As such, we agree with Patent Owner that persons of ordinary skill in the art would have understood “caching the one or more packets” to mean “caching the one or more entire packets.” the claim limitation of “caching the one or more packets” to mean “caching one or more entire packets,” in the context of the ’572 Patent.

“to its temporal aspect of when caching of packets occurs, i.e., its claim construction that such caching occurs during a swapping of rule sets. As discussed above in Section II.B, we are not persuaded that the limitation “caching the one or more packets” requires that the caching must occur only while the rule sets are swapped. We are persuaded, however, that Roese, Huima and Hayter teach, as proposed by Petitioner, the caching of at least some portion of a packet while rule sets are being swapped. As discussed above, we are persuaded that Roese teaches that when the rapid response identifier signal is received, the response system initiates the process of configuring the forwarding engine with the one or more policies and/or PERs, and Huima teaches that in response to receiving a signal to change the rule set, packet processing pauses. Ex. 1005 ¶¶ 47, 52; Ex. 1006 ¶ 31. We agree with Petitioner’s assertion that persons of ordinary skill in the art would have understood that a network device should pause the processing of any pending packets and any incoming packets that arrive after the instruction to change the rule set but before the change is completed, in view of Roese and Huima. Pet. 47 (citing Ex. 1003 ¶ 171). Further, we continue to be persuaded that Hayter teaches using a packet processor with an integrated cache to store at least portions of packets in the L2 cache, and we are persuaded that such storage would occur while awaiting processing to begin again.
