“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. For the reasons described below, we are not persuaded by Petitioner’s argument and evidence.” slip op. at 14
- Skill levelSkill level petitioner adoptedDecided for petitioner
“Petitioner asserts that a person of ordinary skill in the art “had a bachelor’s degree in electrical engineering, computer engineering, computer science, or a related field, and approximately 2-3 years of experience in the design or development of telecommunication systems, or the equivalent” and that “[a]dditional graduate education could substitute for professional experience, or significant experience in the field could substitute for formal education.” Pet. 13–15 (citing Ex. 1003 ¶¶ 18–20). Patent Owner does not address this issue in the Preliminary Response. As Patent Owner does not dispute Petitioner’s characterization of the level of skill in the art, and because we find it generally consistent with the disclosures of the ’797 patent and the prior art, we adopt it for purposes of this analysis.

“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

- Disclosure Requirements (§112) › Written description (Ariad)Written description adequateEntitled to earlier dateDecided for patent owner
“written description. To satisfy the written description requirement of 35 U.S.C. § 112 ¶ 1, the specification must “clearly allow persons of ordinary skill in the art to recognize that the inventor invented what is claimed.” Ariad Pharm., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (internal brackets omitted) (en banc) (quoting Vas–Cath Inc. v. Mahurkar, 935 F.2d 1555, 1563 (Fed. Cir. 1991)). Thus, the specification must reasonably convey to those skilled in the art that the inventor possessed, at the time of filing, the subject matter that he or she has claimed. Id. “[T]he level of detail required to satisfy the written description requirement varies depending on the nature and scope of the claims and on the complexity and predictability of the relevant technology.” Id. Whether a specification complies with the written description requirement is a question of fact. Id. at 1351, 1355. Entitlement to a filing date extends only to subject matter that is disclosed, not to that which is obvious. Lockwood v. Am. Airlines, Inc., 107 F.3d 1565, 1571–72 (Fed. Cir. 1997).” slip op. at 7
- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for patent owner
“We determine that because the open ended term “comprising” was used in the original claim reciting “a” signal, the recitation of “a” signal and “one or more” signals would have the same scope. An indefinite article, such as “a,” in patent parlance encompasses “one or more” when used, as here, in open-ended claims containing the transitional phrase “comprising.” KCJ Corp. v. Kinetic Concepts, Inc., 223 F.3d 1351, 1356 (Fed. Cir. 2000). “Unless the claim is specific as to the number of elements, the article ‘a’ receives a singular interpretation only in rare circumstances when the patentee evinces a clear intent to so limit the article.” Id. Thus, the claim as amended, which removes the open ended preface “comprising” and changes the modifier of “select signals” from “a” to “one or more,” does not change the scope of the claim in that respect. It merely is a different phrasing. Thus, as we stated in the Institution Decision, any description of a system with one signal would necessarily support a claim to one or more signals. Inst. Dec. 28. Additionally, the claim, as amended, does not suggest there is choice between alternatives that would meet this claim. For example, the claim does not require a choice between a first type of signal and a second type of signal. The claim recites “one” signal, which can be optionally accompanied (“or”) by “more” signals.” slip op. at 8
