“Patent Owner, in focusing on this portion of the ’226 patent disclosure, does not adequately explain why buffer cells and configuration memory cells must be included in the proper construction of “wide configuration data port,” and seeks to import a functional description of the use of a wide configuration data port (“that allows parallel updating of logic cells in a programmable array through use of buffer cells”) into the claim construction. PO Resp. 15–17; PO Sur-reply 2–4. While the discussion in the ’226 patent describes an example of a wide configuration data port used in a specific way that aligns with Patent Owner’s proposal (Ex. 1001, 4:45– 59), other examples of the use of a wide configuration data port are included (id. at 4:59–65), and therefore we do not agree that one of ordinary skill would understand this use to be part of the construction of the term. We agree with Petitioner that the proper construction of the term does not require buffer cells. See Pet. Reply 4–6. Rather, we note that the specification of the ’226 patent contrasts loading of data to an FPGA in a byte serial fashion through a narrow port, which “results in [] long reconfiguration times,” with the use of a wide configuration data port, and therefore we determine that one of ordinary skill would understand the wide configuration data port, in contrast to the byte serial “relatively narrow” port, to include parallel connections between cells in the dies. See Ex. 1001, 4:3– 9. This additionally is consistent with certain arguments by Patent Owner, for example in the Patent Owner’s Response, which opens with a discussion of the “innovative” processor’s arrangement of die-area contacts, such as through-silicon vias, “into a wide configuration data port” and we find that description more consistent with the proper construction of this term. PO Resp. 1–2; see also PO Sur-reply 2–3 (“Arbor’s experts have been consistent that the word ‘wide’ in this term requires a sufficient number, and appropriate arrangement, of connections between the memory die and the programmable array to permit parallel updating of the array.”)” slip op. at 15
- Claim Construction › Functional claiming / §112(f) means-plus-function › Corresponding structure / algorithm (indefinite if none)Decided for petitioner
“While corresponding structure need not include all things necessary to enable the claimed invention to work, it must include all structure that actually performs the recited function.” Default Proof Credit Card Sys. Inc. v. Home Depot U.S.A., Inc., 412 F.3d 1291, 1298 (Fed. Cir. 2005). Conversely, structural features that do not actually perform the recited function do not constitute corresponding structure and thus do not serve as claim limitations. Chiuminatta Concrete Concepts, Inc. v. Cardinal Indus., Inc., 145 F.3d 1303, 1308–09, (Fed. Cir. 1998); see B. Braun Med., Inc. v. Abbott Labs., 124 F.3d 1419, 1424 (Fed. Cir. 1997) (“[S]tructure disclosed in the specification is ‘corresponding’ structure only if the specification or prosecution history clearly links or associates that structure to the function recited in the claim.”). Patent Owner’s arguments regarding buffer cells connected with memory configuration cells using die-area interconnections requires that the buffer cells be located on a different die than the memory configuration cells, but the ’226 patent discloses only that “[t]he buffer cells 88 are preferably a portion of the memory die 66” and not that they always are on the memory die, and also that the significantly increased number of connections to the cache memory die may allow the cache memory die to replace configuration bit storage on the FPGA die. Ex. 1001, 4:50–54, 4:59–63. Thus, we decline to require in the corresponding structure that buffer cells or configuration memory are included on any die element. Rather, we find that what is disclosed as actually performing the recited function of “reconfiguring the programmable array within one clock cycle” is “a wide configuration data port and contact points formed throughout the area of the first integrated circuit die element and another integrated circuit die element.” The support for this is found in the ’226 patent’s comparison of the long reconfiguration times through a narrow port (Ex. 1001, 4:3–9) with the time to reconfigure through a wide configuration data port with a significantly increased number of connections (id. at 4:45– 65), and the implementation of this in a module that has multiple dies “which have a number of corresponding contact points, or holes, 70 formed throughout the area of the [die] package” (id. at 4:9–20). The use of a wide configuration data port, as per our construction, implicates two die elements. This was reflected in our preliminary claim construction, for which the corresponding structure described “contact points distributed through the first integrated circuit die element and the third integrated circuit die element.” Dec. on Inst. 29. As the function is “reconfiguring the programmable array within one clock cycle,” one of the die elements is the first integrated circuit die element, which includes the programmable array. slip op. at 19

“Obviousness Analysis A claim is unpatentable under 35 U.S.C. § 103(a) if the differences between the claimed subject matter and the prior art are such that the subject matter, as a whole, would have been obvious at the time the invention was made to a person having ordinary skill in the art to which the subject matter pertains. See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of underlying factual determinations, primarily: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and (4) objective evidence of nonobviousness. Graham, 383 U.S. at 17–18.6 Petitioner asserts that claims 1–2, 7–8, 10, 12–13, and 17–18 are unpatentable under § 103 as obvious in view of Paxton and Sutton. See Pet. 6, 18–64.

“Patent Owner argues that “[t]he plain and ordinary meaning of the terms “determining . . . a first plurality of log entries” and “determining . . . a second plurality of log entries” is “identifying” or “ascertaining” log entries.” Prelim. Resp. 16. Patent Owner also argues that “[t]he terms “provisioning, . . . based on the determined correlation, . . . rules configured to identify the first plurality of packets received by the network device,” and “provisioning, . . . based on the determined correlation, . . . rules configured to identify the second plurality of packets transmitted by the network device” (“provisioning rules”) . . . should be given their plain and ordinary meaning—rules configured to identify packets.” Prelim. Resp. 20. Neither party, however, argues that the prior art arguments presented in the Petition turn on the construction of these terms. Instead, it appears that they are raised as claim construction issues only because Petitioner is challenging the language under Section 112. We will discuss the Section 112 arguments below, but do not see a dispute about the constructions offered by the parties above the makes a difference in the prior art analysis and, therefore, do not construe these terms at this time. See Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999).” slip op. at 10

“respect to this limitation for several reasons, including that Petitioner’s “alleged rule generation and provisioning” is responsive to detecting malicious activity, not “based on the determined correlation.” Prelim. Resp. 38. On this record, we agree with Patent Owner. The claims require “generating, by the computing system and based on the determined correlation, one or more rules configured to identify packets received from the first host.” We do not have sufficient argument or evidence to show that one of ordinary skill in the art would have found it obvious to generate these rules “based on” the determined correlation.” slip op. at 16
