“a POSA would have understood that one of the limited number of design options would have been to implement the security service as part of a controller configured to perform DPI analysis on packets, and a POSA would have had a reasonable expectation that the controller would have been successful in performing DPI analysis. Id. at 18–19 (citing Ex. 1004 ¶ 79 (making an identical statement)). No additional discussion, explanation, or evidence on these points were provided at the Petition stage. Patent Owner argues that: The mere fact that the security service may share certain common technical characteristics with the controller (i.e., its connection to the network switch and the hardware in which these two separate entities are implemented) cannot in and of itself suggest to a POSA that the function carried out by the security service should also be performed by the controller or that the controller should be configured to perform that function (i.e., deep packet inspection). PO Resp. 21–22 (citing Ex. 2025 ¶¶ 54–55). We agree. Though Petitioner asserts that there are a “limited number of design options” and that it would have been obvious to combine the different components of Lin, Petitioner does not establish that a controller configured to perform DPI analysis on packets was a known solution, and thus one of the limited design options. As discussed in KSR: When there is a design need or market pressure to solve a problem and there are a finite number of identified, predictable solutions, a person of ordinary skill has good reason to pursue the known options within his or her technical grasp. If this leads to the anticipated success, it is likely the product not of innovation but of ordinary skill and common sense. In that instance the fact that a combination was obvious to try might show that is was obvious under § 103. KSR, 550 U.S. at 421. Besides asserting the combination would have been “obvious to try,” Petitioner provides no other analysis or reason why one of skill in the art would have modified the teachings of Lin to obtain the claimed controller. Thus, Petitioner has not established by a preponderance of the evidence that the teachings of Lin render obvious all of the features of claim 1.” slip op. at 17

“Patent Owner argues, and we agree, that the cited portions of Raz do not disclose a LAG between two switches. PO Resp. 8–9. Petitioner acknowledges this; as stated in Petitioner’s Reply, “Petitioner has always acknowledged that Raz addresses the use of subports within an LSR, but a [person of ordinary skill in the art] would have found it obvious from Raz to use Ethernet physical data ports of a router or switch in an Ethernet LAG to communicate high-speed packet streams in [an] MPLS network.” Pet. Reply 2 (citing Pet. 15, 19, 22–25; Ex. 1021 ¶ 13; Ex. 1006, 1:16–19, 2:23– 31, 7:7–29, 11:3–12, 13:16–19, 14:42–44, 15:56–58, 17:7–9). 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. Reply 4 (emphasis added) (citing Ex. 1006, 2:23–25, 7:7–16, 7:22–26, 11:3–29, Fig. 5; Ex. 1021 ¶ 18). 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

“[c]laims 1–13, 15–24 and 26 set forth above in Ground 1.” Pet. 52. 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

“Considering the evidence of record on both sides, we find Petitioner’s argument persuasive that Baker teaches a “mapping” as recited in limitation 1.4. Baker’s disclosure of a “mapping” is explicit. See, e.g., Ex. 1005 ¶ 69, 83. And the evidence shows that this mapping occurs “in advance of a communication,” and may, for example, take place in the head node as part of the Administer Ring routine. See, e.g., Ex. 1005 ¶¶ 51–56, 76. That intermediate rings are ultimately configured to simply forward traffic “according to preconfigured rules” (Ex. 1005 ¶ 87) rather than to perform more complicated routing has no pertinent bearing on the process corresponding to the recited “mapping” step, which occurs “in advance” of the communication and any such forwarding (id. ¶ 76).” slip op. at 26

“allocating bandwidth as part of its resources and that, in light of Wright, a person of ordinary skill in the art would have had reason to make this allocation for each of the links in of the physical topology (see Ex. 1006 ¶ 18 (“bandwidth allocation at each link”)) using information from both (1) the bandwidth requirements of Baker’s logical connections and (2) the mapping between Baker’s logical and physical topologies. As Petitioner persuasively argues, we find that Wright’s teaching of further details on ensuring the availability of bandwidth, in a similar context, would have been sufficient motivation for a person of ordinary skill in the art to incorporate Wright’s teachings into Baker’s method. We also determine that whether Wright, itself, teaches a mapping step is not the determining factor because Petitioner relies on Baker, not Wright, for teaching mapping limitation 1.4. Nevertheless, Wright does teach allocating bandwidth using the same information that would be available as a result of Baker’s mapping, including the logical (“restricted”) topology and the physical links associated with that topology. In particular, we agree with Petitioner that a person of ordinary skill in the art would have understood that allocating bandwidth to the physical links (step 510 of Figure 5) requires knowing which physical links correspond to Wright’s restricted topology. See Pet. 36; Pet. Reply 22–23; Ex. 1007 ¶ 17; Ex. 1003 ¶¶ 94–96; Ex. 1036 ¶¶ 49–51. We also disagree with Patent Owner that Petitioner has failed to adequately explain how a person of ordinary skill in the art would have modified Baker’s method to apply Wright’s teachings on bandwidth allocation, such as how Baker’s head node N0 would have been modified. See PO Resp. 31–32. Based on the level of ordinary skill and the level of detail in Baker, Wright, and the ’431 patent, and crediting Dr. Houh’s testimony, we find Petitioner’s argument persuasive that such modification would have been within the capability of someone of ordinary skill in the art. See Pet. 17–20 (citing Ex. 1003 ¶¶ 42–46, 48). And we agree with Petitioner that modifying Baker with Wright’s teachings would have been “nothing more than the combination of known elements . . . according to known methods . . . to yield predictable results.” Pet. 20 (citing Ex. 1003 ¶ 47).” slip op. at 32

“For reasons explained in the Petition and Petitioner’s Reply, we agree with Petitioner that the Baker–Wright–Holender ’699 combination teaches summing the two bandwidths determined in “allocating” steps 12.5 and 12.7 to determine a total allocation for each of the physical links—motivated by the known need to ensure that bandwidths do not exceed the available physical link capacity. We disagree with Patent Owner that Holender ’699’s discussion of summing is merely describing a physical constraint. Holender ’699 teaches normalizing the logical link capacities, which requires summing the logical link capacities. See Ex. 1007, 8:38–51. We credit Dr. Houh’s testimony that this “confirms that [Holender ’699’s] teachings about summing are not simply ‘explaining a physical constraint,’ but actually performed.” Ex. 1036 ¶ 61. Holender ’699 refers to capacities 𝐶𝐶𝑗𝑗 as “logical link capacities for each logical link j over all logical networks. Ex. 1007, 6:52–55. But when mapped to physical links, Holender ’699 denotes capacities 𝐶𝐶𝑘𝑘𝑘𝑘 as “capacities of the logical links [𝑙𝑙] that need capacity on the k:th physical link.” Ex. 1007, 8:38–43. In other words, they are the capacities, or bandwidths, allocated to each physical link 𝑘𝑘 for implementing associated logical link 𝑙𝑙. See also id. at 6:60–67 (describing a matrix designed to indicate “if logical link j needs capacity on the k:th physical link.”).” slip op. at 50

“Relying on Dr. Houh’s testimony, Petitioner argues that a person of ordinary skill in the art “would have had a working knowledge of the networking art that is pertinent to the ’431 patent, including network communications techniques and bandwidth management methodologies,” and “would have had a bachelor’s degree in computer science, computer engineering, electrical engineering, or an equivalent, and two years of professional experience relating to network communications including the use of logical topologies and bandwidth management. Lack of professional experience can be remedied by additional education, and vice versa.” Pet. 3 (citing Ex. 1003 ¶¶ 18–20). Patent Owner adopts Petitioner’s proposed definition of the level of ordinary skill. PO Resp. 3.

“necessary because the construction does not resolve any contested issues. Pet. Reply 8–10 (citing Ex. 1005 ¶¶ 16, 62; Ex. 1006 ¶¶ 5, 24; Ex. 1003 ¶ 96; Ex. 1036 ¶¶ 49–50). But if a construction is necessary, Petitioner argues that the we should construe in response to as “using,” consistent with how the claimed invention is described in the ’431 patent. Id. at 10–11 (citing Ex. 1001, 2:52–6:10, 8:52–9:2; Ex. 1036 ¶¶ 7–11). Petitioner disagrees that the term means “based on” because limitation 1.3 uses the phrase based on, suggesting that the applicant made a conscious decision to use different language in limitation 1.5. Id. at 11 (citing Ex. 1036 ¶ 11). Patent Owner responds that its two proposed constructions are synonymous, and argues that Petitioner agrees that in response to encompasses “using” or “using information from.” PO Sur-reply 8 (citing Ex. 1001, 2:22–26). Patent Owner contends that its proposed construction resolves a controversy because in Patent Owner’s view, the Baker–Wright combination does not use information from the recited mapping to allocate bandwidth. Id. at 9–12 (citing Ex. 1006 ¶¶ 5, 17, 24; Ex. 2009, 52–56; Ex. 2008 ¶¶ 62–76). Similarly, Patent Owner contends that Holender ’699 does not teach mapping. Id. at 12–13 (citing Ex. 1007, 3:15–17; Ex. 2008 ¶¶ 89–92). We see no significant difference between Petitioner’s proposed construction of in response to as “using” and Patent Owner’s proposed construction as “using information from.” Thus, it does not appear that the construction of in response to is in controversy.
