“Following institution, Patent Owner maintained the same level of ordinary skill proposed in its preliminary response and did not address our discussion of the level of ordinary skill in the art in the Institution Decision.

For the reasons discussed in the Institution Decision, we adopt and apply for this Decision the level of ordinary skill articulated by Petitioner and used previously in our Institution Decision. See Dec. 8–10. In light of our review of the complete record, we find that this formulation is consistent with the ’825 patent, the prior art of record, and is supported by the testimony of Dr. Baker.

“We agree with Patent Owner that the desired signal and interferer signal must be received at the same time. The plain language of the claim requires the wireless transceiver to “receiv[e] a wireless signal having a desired signal and an interferer signal,” the determining of a signal strength of the interferer signal and the determining of a signal strength of the desired signal must be performed at the same time; otherwise, the determinations of signal strengths would not be of the same wireless signal. 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. Id. (“Signal cA is 0 when signal RSS is greater than S4 and signal RSSn is at the 11 Dr. Baker’s reply declaration correctly quotes Rauhala paragraph 17 but cites to paragraph 18. We deem this harmless error. same time smaller than Sn. . . . Signal cM is 1 when signal RSS is not greater than S4 and signal RSSn is at the same time at least Sn. Otherwise, signal cM is 0.”). 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). We do not see a lack of precision in Rauhala’s “either/or” statements.” slip op. at 30

“When asked at his deposition to explain Rauhala’s use of the word “or” regarding the functioning of detector DET, Dr. Baker asserted that “[detectors] can be designed to determine RSS or RSSn.” Ex. 2016, 85:5– 12. We find Dr. Baker’s testimony that “it’s reasonable that if you can design . . . the detector to detect one or the other, you can also design it to detect both” to be without factual support. Id. at 85:13–16. He points to no textbook or other independent evidence to support that would have led one of ordinary skill to design such a detector or to support that one of ordinary skill would have understood Rauhala’s detector to be so designed. Furthermore, Dr. Baker recognizes that “Rauhala doesn’t teach the details of what’s in the detector.” Id. at 91:6–7. We give little weight to Dr. Baker’s unsupported testimony that one could design a detector to detect both RSS and RSSn from the same wireless signal.

We find that the language of the claims supports Patent Owner’s argument that the desired signal and the interferer signal are received together. As discussed infra, claim limitations 7.7 and 7.8 recite determining a signal strength of the interferer signal and determining a signal strength of the desired signal. These determinations must be performed at the same time; otherwise, the determinations of signal strengths would not be of the same wireless signal. See Larson II Decl. ¶ 70; Baker II Decl. ¶¶ 48–49 (explaining that consideration of signal strengths detected at the same time would be “essential”).

“Further, we find the testimony of Patent Owner’s declarant more persuasive based at least on his consideration of Swenson as a whole and his more detailed analysis and explanations. For example, Patent Owner’s declarant explains in detail why, “[i]n the context of a HTTP GET request and response, as disclosed in Swenson, the message does not constitute a single packet but a flow of packets:” Furthermore, Swenson discloses that the steering device 130 “sends an ICAP request message 516 comprising [a] HTTP GET request header and a portion of the [HTTP] response payload to the network controller 140, which inspects the message to determine whether to monitor the flow or optimize the video.” Ex. 1007 [0065]. In the context of a HTTP GET request and response, as disclosed in Swenson, the message does not constitute a single packet but a flow of packets. The reference to a HTTP request and response “header” and “payload” are thus not references to the header and payload of a packet. A POSA would know that despite common parlance references to “HTTP packets,” HTTP does not pertain to individual packets, whereas packet transmission is governed by the TCP protocol. HTTP utilizes TCP to exchange data such that information may be used by an end user (e.g., a video or audio stream). Even assuming that Swenson’s controller were analyzing the header and payload of an HTTP request/response, a POSA would understand that this analysis is not at the packet but at the flow level and thus does not constitute deep packet inspection. Ex. 2025 ¶ 69. Petitioner’s declarant merely responds by reiterating what was previously stated: Swenson is explicit in stating that its inspection techniques include inspection of “a portion of the [HTTP] response payload.” . . . A POSA would have understood the analysis of the “response payload” to be DPI by a DPI-capable controller, as DPI refers to monitoring the payload of a packet.” slip op. at 15

Petitioner argues that LAGs were well known and, “[w]hile PO argues that Raz teaches the use of a single high-speed link to communicate between LSRs, that is merely a design choice.” Pet. Reply 3 (citing Ex. 1021 ¶¶ 15–17; PO Resp. 8–9). Further, Petitioner argues “[i]t would have been obvious to a [person of ordinary skill in the art] that high-speed packet streams could be communicated between switches or routers through a physical tunnel port of a LAG.” Pet. Resp. 3 (citing Ex. 1021 ¶¶ 15–17) (emphasis added). Among other problems, though, those arguments were not in the Petition; the Petition does not describe modifications of Raz’s teachings, much less establish those modifications as a “design choice.” See Pet. 25; see also PO Sur-reply 3. Further, we agree with Patent Owner that Raz is fundamentally different with its teachings of multiplexing the outputs of multiple slow- speed subports/processors into a single stream for transmission across a single high-speed link. PO Resp. 7–9, 12–13, 15–16; PO Sur-reply 4–5. As stated in Raz, “[t]he present invention provides a subport forwarding and provisioning mechanism whereby a plurality of subports comprising slower speed processors are used to perform the packet processing for a higher speed packet stream.” Ex. 1006, 6:24–27. Additionally, where Raz describes communication between two LSRs, Petitioner acknowledges that Raz teaches that its cited second LSR assigns the port on which it will receive a data packet. Pet. Reply 4; Ex. 1021 ¶ 20 (“in Raz, the second LSR chooses the subport that will be used to transmit the data packet from the first LSR and receive the data packet at the second LSR”). According to Petitioner, Raz teaches that “a first LSR generates a data packet label in which a port serial number is encoded and sends the label to a preceding LSR. Subsequently, the preceding LSR sends a data packet to the proper subport for processing. The process is then repeated in sending the data packet from the first LSR to a second LSR.” Pet. Reply 4 (citations omitted). “This technique just as easily could have been implemented to identify a single physical tunnel port through which a data packet in a first router or switch would be communicated to a second router or switch via a LAG.” Pet.

Again, these arguments were not made in the Petition (see Pet. 22–25), and Petitioner’s assertions that Raz’s teachings “just as easily could have been implemented” in the manner claimed is improper hindsight and inconsistent with the fundamental differences between Raz’s multiplexing within an LSR and the claimed link aggregation and port assignment between MPLS/LAG switches.” slip op. at 8

Further, Petitioner states that “[f]or independent [c]laims 1, 15, and 26, Ferguson builds on the previous analysis of Raz by disclosing a system for communicating packets between switches and routers in an MPLS network.” Pet. 52; see Pet. 52–55. Critically, though, Petitioner does not specifically explain how the combined teachings of Raz and Ferguson would satisfy individual claim elements. Among other problems with Petitioner’s proposed combination, Petitioner does not adequately explain how or why a person of ordinary skill would have combined the references to include the claimed port assignment and packet labeling for transmission of a packet from a preceding node and then between a first and second MPLS switch. See Pet. 56–59. Instead, Petitioner generally advocates for the combination of Raz and Ferguson, arguing for example that “both Raz and Ferguson are directed to solving the problem of ensuring enough bandwidth is available to communicate high-speed packet streams through an MPLS network.” Pet. 57 (citing Ex. 1006, 10:60–11:12, 14:33–41, 15:47–55, 17:1–9, Fig. 5; Ex. 1007, 1:28–42, 2:54–57, 4:55–60; Ex. 1004 ¶¶ 247–249). Further, Petitioner contends a person of ordinary skill “would have understood from the disclosures in Ferguson that techniques for utilizing an Ethernet physical data port in a LAG to communication data packets between routers or switches in an MPLS network are also applicable to the use of subports transmitting the data packets within the routers or switches, and vice versa.” Pet. 59 (citing Ex. 1004 ¶ 250; Ex. 1007, 5:61–6:6); see Pet. 56–59; Pet. Reply 20. But Petitioner does not adequately explain how the proposed combination of Raz and Ferguson would cure the deficiencies addressed above in Petitioner’s analysis of Raz for Ground 1. Among other problems, none of Petitioner’s arguments adequately address port assignment and labeling in the proposed combination, much less adequately explain why the proposed combination would satisfy the challenged claims. See Pet. 55–56. As Petitioner does not adequately explain how the teachings of Raz and Ferguson might be combined to cure the deficiencies addressed above, we additionally determine Petitioner’s arguments and evidence advanced for the combination of Raz and Ferguson do not establish obviousness by a preponderance of the evidence for any of claims 1–26.” slip op. at 11

Moreover, we agree with Dr. Cooklev (Ex. 2004 ¶ 37) that Paulraj is consistent in describing separate transmit units and receive units throughout its disclosure, and without an appropriate mapping of Paulraj’s alleged teachings of transmit/receive antennas to the challenged claims in the Petition, Petitioner has not carried its burden to show unpatentability under such a theory, even if it were timely.” slip op. at 16

“As Patent Owner has noted (PO Resp. 16), the Specification of the ’936 patent repeatedly and consistently states that the mobile device is able to “switch itself” or “switches itself.” Ex. 1001, 5:1–4, 8:9–12, 8:36–39. The Specification of the ’936 patent also describes that the device “can decide the preferred mode to be in.” Id. at 4:8–9 (emphasis added). The Specification of the ’936 patent further states that the device “is dynamically software reconfigurable for the various environments.” Id. at 2:35–36 (emphasis added). In contrast, there is not any description, none, in the Specification of the ’936 patent of the user of the device issuing a command to the device at the time of making a functional switch to cause the device to switch function.11 In light of such disclosures, we agree with Patent Owner that a fundamental aspect of the invention of the ’936 patent is that dynamic configuration occurs without user intervention, i.e., without user command at the time of the change in configuration. PO Resp. 13. In our view, it is not consistent with the Specification of the ’936 patent to read “dynamically configurable” as encompassing manual reconfiguration by user intervention, i.e., user command at the time of reconfiguring. Reading “dynamically configurable” as encompassing manual reconfiguration by user intervention, i.e., user command at the time of reconfiguring, is also contrary to the prosecution history of the ’936 patent.” slip op. at 16

“We have construed “dynamically configurable” as “configurable when and as needed and in real time, without the need for user intervention,” and explained that “without the need for user intervention” means absent user command at the time of dynamic configuring. See Section II.C.2., supra. Based on that construction, we are not persuaded by Petitioner that Regnier dynamically configures its device from a first function to a second function, as Petitioner asserts. As explained by Petitioner, Regnier’s device reconfigures its functionality in response to user selection of the desired application program, to provide the functionality corresponding to the user selected application program. Pet. 51–52. Patent Owner notes that Petitioner’s rationale “relies on manual, user- initiated conversions.” PO Resp. 36. Patent Owner explains: Petitioners argue that Rautiola in view of Regnier “describes that the client device dynamically converts between functions by downloading a client portion of an application and converting between different application services that are allowed by a server on a dynamic basis and chosen dynamically by a user.” Pet. 48. These allegations combine two distinct parts: (1) providing a client portion of an application for download; and (2) determining whether to allow the client device to use a different application service each time the client requests converting from a first to second application. Ex. 2031, ¶74. According to Petitioners’ own arguments, both parts depend on manual user requests. For providing a client portion, the Petition states that “Regnier teaches that “client portion 291” 130 upon a request from the user.” Pet. 49 (quoting Ex. 1006, 5:52-5:54) (emphasis added). The Petition also repeatedly acknowledges that a user request initiates Regnier’s process to determine whether to allow a client device to use an application. Id., 49 (alleging that Regnier’s server maintains user profiles that determines whether users can execute applications), id., 51-52 (alleging that “Regnier further explains that each time a user selects an application . . . ”); id., 53 (alleging the server’s resource manager allows “users to choose dynamically among shared resources”).
