Dynamic Drinkware, 800 F.3d at 1378 (citing Tech. Licensing Corp. v. Videotek, Inc., 545 F.3d 1316, 1326–1327 (Fed. Cir. 2008) (discussing the burden of proof in inter partes review). Petitioner must explain with particularity how the prior art would have rendered the Challenged Claims unpatentable. 35 U.S.C. § 312(a)(3); 37 C.F.R. § 42.104(b)(4) (“The petition must specify where each element of the claim is found in the prior art patents or printed publications relied upon.”). IV. PATENTABILITY ANALYSIS A. Legal Standards A claim is unpatentable under 35 U.S.C. § 103(a) if the differences between the subject matter sought to be patented 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 said (2007). The obviousness inquiry requires an analysis of “whether there was an apparent reason to combine the known elements in the fashion claimed by the patent at issue.” KSR, 550 U.S. at 418 (citing In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006) (requiring “articulated reasoning with some rational underpinning to support the legal conclusion of obviousness”)). Petitioner cannot satisfy its burden of proving obviousness by employing “mere conclusory statements,” but “must instead articulate specific reasoning, based on evidence of record, to support the legal conclusion of obviousness.” In re Magnum Oil Tools Int’l, Ltd., 829 F.3d 1364, 1380 (Fed.

Rather, the new evidence cited by Petitioner is improperly being used to supply evidentiary support for an argument made in the Petition that lacked such support.

    “From this description in Burrows, it is clear that index 70 has no sense of ranking, and that Burrows’ system overall has no sense of ranking prior to a query; thus, adding or deleting a webpage from the index does not change a ranking that does not yet exist. It is also clear that, if a page is flagged as deleted, it will be ignored by the query module when the query module queries the index and ranks the identified qualified pages. Id. at 15:12–16, 15:21–22. The webpage’s rank is not decreased, as the webpage is never ranked in the first place. As Mr. Occhiogrosso testifies: web page. A “polled web site” page cannot be ranked in the Burrows system because the Burrows ranking is performed only after a user query is performed. Only at that time can the Burrows system provide a ranked list (of qualified webpages) for presentation to the user. As Burrows discloses, the Automated Web Browser is robotic in nature and not associated with the queries of users. Ex. 2009 ¶ 181. Mr. Occhiogrosso’s testimony on this point is consistent with Burrows’ description, credible, and entitled to substantial weight. We have considered Mr. Lipoff’s testimony that a skilled artisan “would have understood that combining Burrows’s polling mechanism receiving no response into Kovatch would decrease the entries’ ranking or placement in Kovatch’s destination tree in order to further limit the pages that may not be of interest to the user.” Ex. 1002 ¶ 172 (citing Ex. 1006, 1:38–46). That testimony, however, is conclusory and lacks persuasive reasoning. Moreover, the passage in Burrows to which it cites (Ex. 1006, 1:38–46) does not teach or suggest decreasing the ranking of webpages.

Mr. Lipoff repeats this statement in his testimony without identifying the basis for it, rendering that testimony of little value. Ex. 1061 ¶ 24. In any case, it appears that Petitioner and Mr. Lippoff are arguing that a general notion of processing cost any time computer processing occurs would lead a skilled artisan to decrease a webpage’s rank based on response time.

    “summarized above, we find Patent Owner to have the better position. In particular, we agree with Patent Owner that the combination of Hsia and Black fail to teach or suggest simultaneously delivering non-overlapping beams. The combination also fails to teach or suggest producing beam patterns that include both overlapping and non-overlapping beams. PO Resp. 34. To begin, while we recognize that Hsia discloses overlapping and non-overlapping treatment patterns, those patterns are achieved by the sequential delivery of laser beams as a user physically moves a single handpiece that delivers a single beam across the skin of a patient. Ex. 1004 ¶ 68, Figs. 8 and 9; Ex. 2001 ¶¶ 73–74. Black does not cure that deficiency as Black does not disclose treatment with non-overlapping beams. Ex. 2001 ¶ 99. Black discloses using a “refractive optics, mirror-based optical delivery device” for the simultaneous delivery of multiple overlapping laser beams. Ex. 1006 ¶¶ 12– 13. The beams align on an optical path and, using different laser beam parameters, deliver treatment at various depths within a combined beam path. Id. ¶¶ 54, 58–59. Thus, while Black may be characterized as creating overlapping beams, we do not find sufficient support for a finding that Black teaches or suggests creating non-overlapping beams for simultaneous delivery, and the claims require both.

Analysis Considering the Wands factors as a whole, we find that the limited breadth of the claims, presence of several working examples, significant amount of direction and guidance provided by the ’087 patent, predictability in treating blood cancers with Bcl-2 inhibitors like GDC-0199, and high level of skill in the art are balanced against a large quantity of experimentation. Based on our consideration of the entirety of the evidence, we find that a preponderance of the evidence supports the conclusion that undue experimentation would not have been required to make and use the invention commensurate in scope with the claims of the ’087 patent. One underlying theme of Petitioner’s contentions and Petitioner’s expert testimony is the repeated contention that clinical trials were not completed by Patent Owner. See, e.g., Pet. 48 (“venetoclax (GDC-0199) was not FDA-approved”); Ex. 1020 ¶ 193. We find these arguments unpersuasive as we agree with Patent Owner that “[i]t is well established that a patent may be secured, and typically is secured, before the conclusion of clinical trials.” In re Montgomery, 67 F.3d 1375, 1382 (Fed. Cir. 2012). Particularly as to the dependent claims, a preponderance of the evidence of record does not support a finding that undue experimentation would have been required to administer three different doses of GDC-0199 starting with 100 mg, to use multiple daily dosing cycles of one day, to continue until disease progression occurs, or to combine with other treatment compounds.

As Patent Owner essentially argues, Cabot (and all references relied upon by Petitioner and Dr. Scordilis) do not pertain to “quantizing a phase difference of the at least one overtone relative to the fundamental tone to embed at least one bit of the data to be embedded” as step 1C-2 requires. See PO Resp. 32–33. Petitioner also relies on Kudumakis to modify Srinivasan in asserting that step 1C-2 would have been obvious, but Petitioner’s reliance on Kudumakis is also faulty as explained below.

As noted above, Dr. Scordilis states that Cabot merely “opens the venue for exploration” for an artisan of ordinary skill to “try to . . . explore” watermarks. Ex. 2011, 75:16–22. Dr. Scordolis’s testimony relates to an “obvious to try” rationale, but neither Dr. Scordilis’s testimony, nor Petitioner’s showing, satisfies the conditions to support that rationale. In particular, Dr. Scordilis does not testify, and Petitioner does not show, that the technique of embedding phase difference codes into a harmonic relative to its fundamental was one of “a finite number of identified, predictable solutions” and a “known option[]” for hiding data.

Moreover, Dr. Scordilis testifies that “[t]he value . . . of Cabot’s work is that he points to the fact that even in this very controlled experiment, although phase is detectable in an A/B type of setup under many, many repetitions, it really opens the venue for exploration that a [person of ordinary skill in the art] would try to capitalize and explore further to develop a watermark.” Id. at 75:16–22 (emphasis added). In summary, Dr. Scordilis testifies that no references (including Cabot) cited in his declaration discuss phase encoding of a harmonic phase relative to a fundamental phase for watermarking, and Cabot merely opens the door so that a person of ordinary skill in the art would “try to . . . explore further to develop a watermark” using harmonic phase coding data.

    “wherein the ordering and annotation function is executed interactively at the time of each user query” contains two requirements: 1) how the function is executed (“interactively”) and when the function is executed (“at the time of each user query”). Petitioner, in effect, reads out of the claim the “interactively” requirement. Petitioner offers no persuasive reason as to why that is correct. See In re Wilson, 424 F.2d 1382, 1385 (CCPA 1970) (“All words in a claim must be considered in judging the patentability of that claim against the prior art.”). Petitioner, for its proposed claim construction of a single requirement, primarily relies on the Specification’s statement that “the ordering and Annotation step 345 is executed interactively, e.g., at the time of every user query.” Ex. 1001, 8:10–12; see Pet. Reply 12–13 (citing the same for the proposition that “[t]he ’676 patent specification also ties the terms together”); Tr. 16:3–12 (“it’s clear the specification is saying that interactively means at the time of every user query”). Petitioner’s reliance on this statement is misplaced. First, Petitioner agrees that the plain and ordinary meaning of “interactively” means “some sort of interaction with the system,” that the inventor did not utilize its own lexicography to redefine the term “interactively,” and that the Specification does not evidence a disavowal of claim scope. See Tr. 19:4–20. Consistent with that, Petitioner acknowledges that the quoted part of the Specification merely is an example, and is not defining “interactively” as limited to that example. See id. at 19:19–25. Second, Petitioner misreads the Specification as indicating that “at the time of every user query” is an example of “interactively.” See, e.g., id. at 21:25–22:1 (“the way I read this is at the time of every user query is modifying what interactively means”). Rather, the better reading of the Specification’s phrase “executed interactively, e.g., at the time of every user query” is that “at the time of every user query” (as opposed to some other time) is an example of when the function may be interactively executed, not that the two phrases on either side of the “e.g.” are synonymous. slip op. at 21

    “Because the above-quoted limitations of claims 1 and 12 plainly require that only a single copy of each data packet be forwarded to the output ports forming a subset (which according to limitations [1.1] and [12.1] forms a LAG), any position of Petitioner asserting the contrary must be contained in the Petition. 37 C.F.R. § 42.204(b)(3) (“the petition must set forth . . . [h]ow the challenged claim is to be construed.”). If not, Patent Owner is deprived of an adequate opportunity to respond, for example, by relying on expert testimony in a declaration to support its Response. Petitioner’s articulated claim construction position regarding forwarding only a single copy is belated, and no explanation has been provided to justify omission of this claim construction position in the § 42.204(b)(3). Thus, the argument is not entitled to consideration. Even if we do consider Petitioner’s belated claim construction position, it is nonetheless without merit and we are unpersuaded. Petitioner’s contention is based on the doctrine of claim differentiation, which disfavors reading a limitation expressly stated in a dependent claim into a claim from which it depends. See Liebel-Flarsheim Co. v. Medrad, Inc., 358 F.3d 898, 910 (Fed. Cir. 2004).

    “For several reasons, we are not persuaded by Petitioner that Borgione forwards only a single copy of a packet via the output ports of Borgione’s LAG as identified by Petitioner. Nowhere in the above-cited portions of Borgione is an indication that no other copy or replicated packet will be forwarded via the output ports of Borgione’s LAG. The above-cited description discusses one forwarding instance but does not represent that there is no other forwarding of a copied or replicated packet. To the contrary, the cited text indicates that other copies or replicated versions would still be forwarded via the output ports of the same LAG. Borgione describes that upon receipt of a packet with a multicast destination address, i.e., a multicast packet, a linking node such as node 110 identifies the network nodes subscribing to the multicast group and replicates the packet. Ex, 1006, 6:14–17. Borgione further states: “The replicated multicast packets can then be forwarded to the identified network nodes [such as node 120].” Id. at 6:17–18.

    “First, the articulated motivation to combine is overly general and is disconnected with the circumstances and requirements of Devi. Mazzola discloses an address-translation mechanism using table look-up, as discussed above in Section II.D.3. It makes no mention of and is not concerned with aggregated links, sending a packet to just one port in an aggregated link, or load distribution among the ports in an aggregated link. It makes no distinction between one port and a plurality of ports, as it discloses that the index value retrieved from a table may be associated with either one port or a plurality of ports. Ex. 1007, 9:28–31 (“In response, the LTL translates the received index to a signal that selects a port or a group of ports for receiving the data frame.”). Although Mazzola describes that each port is associated with a unique index value and a VLAN “color” identifier (Ex. 1007, 3:12– 14), Mazzola also describes that “[t]he destination of any frame may be one or more ports” (id. at 6:16–17) and that a port can be a multicast port including a group of ports (id. at 6:20–24). The “efficiency” Mazzola mentions appears to be using a look-up table for address conversion versus not using a look-up table, and has little, if anything, to do with associating an FMID with a port versus associating an FMID with a group of ports or a LAG. Further, with Devi’s disclosure of sending only one packet to a LAG and load balancing among the ports in a LAG (limitation [1.2]), it is uncertain whether table look-up as described in Mazzola would even work in that environment. Petitioner does not address entries have to be revised. The statement of increased efficiency is speculative in the context of Devi. Second, Petitioner has over-simplified the issue with limitation [1.3] and has not adequately explained how Mazzola’s address-translation mechanism would be incorporated into Devi without affecting those portions of Devi relied on by Petitioner to account for limitation [1.2]. It is not adequately explained how Devi would be modified to incorporate teachings from Mazzola. Petitioner does not adequately address whether the proposed combination would impact Devi’s components and functionality that are also relied on by Petitioner. It is unclear why the purported combination would have been successful.” slip op. at 47

    “The problem with the proposed combination is that the express teachings of Brands-Chaum require timing a rapid single bit, and one of ordinary skill in the art would have understood that Menezes’s challenge-response has multiple bits.

    “Petitioner’s argument was a new argument first raised at the hearing. The Reply cites none of the above testimony from Dr. Karp and makes no such argument.

But even if we were to consider it, our opinion would not change because Dr. Karp’s testimony contradicts the express disclosure of Brands-Chaum. See Ex. 2019, 166:8–167:9. As we have repeatedly emphasized, Brands- Chaum requires that “[t]he essential element of a distance-bounding protocol . . . consists of a single-bit challenge and rapid single-bit response.” Ex. 1007, 345 (emphasis added).
