That is, Patent Owner agreed that the Board should use the prior constructions for the same claim terms at issue in this proceeding. Id. at 26:12–16 (“JUDGE MCKONE: -- it sounds like everybody agrees, that we should use the prior claim constructions from [the] other proceedings . . . Do you agree? MR.

Although Patent Owner points to the District Court’s Memorandum in Support of Claim Construction Order (id. at 32 (citing Ex. 2002, 26)) to support its contention that the District Court construed the term “enabled,” as we determined in the Decision to Institute, this portion of the District Court’s Memorandum merely discusses that “hybrid device” is not indefinite, and discusses exemplary operations of the “hybrid device” from which a POSITA “could reasonably ascertain the scope of the claim.” See Dec.

“B. Principles of Law A patent 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 said subject matter pertains.” 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 including: (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 non-obviousness.10 See Graham v.

“patent. See Phillips, 415 F.3d at 1315–17. The term “extrusion lamination” does not appear anywhere in the ’482 patent outside of issued claim 1, but our understanding is supported by the prosecution history of the ’482 patent. Claim 1 as originally filed in the application that issued as the ’482 patent recited, in relevant part, “a reinforcing scrim of interwoven strands for supporting tensile forces in multiple directions; and at least one layer of thermoplastic material affixed to a side of the reinforcing scrim for providing a weather-resistant barrier.” Ex. 1002 (’482 patent prosecution history), 33. In response to a rejection of the claims as anticipated by U.S. Patent No. 5,523,357 to Peterson, describing a rubber mill calendering process, the applicant amended claim 1 to add the phrase “by extrusion lamination.” Id. at 71, 76. We find nothing to suggest that a person of ordinary skill in the art would have understood that amendment to add a requirement of an additional layer of thermoplastic material, separate and apart from the “at least one layer of thermoplastic material” already recited in the original claim, to serve as a binder between the scrim and the original layer of thermoplastic material. The applicant explained in remarks accompanying the amendment, “Peterson fails to disclose forming a thermoplastic layer over the reinforcing scrim by an extrusion lamination process.” Id. at 71 (italics, underlining, and capitalization omitted). We, thus, find that the added phrase specifies how the recited “thermoplastic material” must be “affixed” to “the side of the reinforcing scrim,” but does not alter the recited function of the thermoplastic material, namely, “for providing a weather-resistant barrier.” Although the applicant’s remarks further state that “[c]ontrarily [to the rubber mill calendering process of Peterson], the roofing underlayment of the present invention is formed by an extrusion lamination process which bonds the various layers together, including the pre-formed films, reinforcement scrim, and slip-resistant material” (id.), claim 1 does not recite “pre-formed films” or “slip-resistant material”; such additional layers are recited in dependent claims 5 (“metallized film”) and 2 (“layer of slip-resistant material”), respectively (Ex. 1001, 6:29, 6:37). Looking finally to the extrinsic evidence of record, including the testimony of the parties’ experts and other exhibits filed by the parties, we find no persuasive evidence to show that the recitation of extrusion lamination requires an additional layer in addition to the recited scrim and the at least one layer of thermoplastic material affixed to a side of the scrim. In that regard, notwithstanding Patent Owner’s contentions, we are not persuaded that “extrusion lamination” and “extrusion coating” are mutually exclusive. Rather, we credit Mr. Kaczkowski’s testimony that extrusion coating would also be considered “extrusion lamination” if, for example, it “results in the extrudate being permanently bonded to the substrate.” Ex. 2020, 28:17–20. While Patent Owner argues that Mr. Kaczkowski’s statement “is nothing more than restatement of the extrusion coating process,” and “[t]o think otherwise would require believing that ‘extrusion coating’ involves a thermoplastic layer that is extruded, and thus coated, onto a substrate with the result being that it is not permanently bonded, i.e., it will delaminate from the substrate” (PO Sur-reply 5), we disagree with Patent Owner’s further contentions that “[s]uch a product makes no sense” and “[u]nder Petitioner’s theories, the [prior art] would not work” (id.). Although there could indeed be extrusion coating processes that would result in coatings that are not permanently bonded, it does not follow that the cited prior art used such processes. Further, although a laminate may be affixed to substrate by an adhesive or other binder, we find no persuasive evidence in the record that the binder must be a separate layer from the laminate.” slip op. at 21

“Having considered the parties’ respective arguments, we find that Petitioner’s contentions are supported by the evidence of record, and we find that Petitioner has articulated sufficient reasoning with rational underpinnings (including support both from the cited prior art and from Mr. Kaczkowski’s testimony) to combine the relevant teachings of Lou and Goodacre. We disagree with Patent Owner’s suggestion it is insufficient that Mr. Kaczkowski opined that a person of ordinary skill would have evaluated the proposed combination based on the combined teachings of the asserted references. As the Supreme Court has explained, 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 it was obvious under §103. KSR, 550 U.S. at 421. Patent Owner does not dispute Goodacre’s teachings or that combining those teachings with Lou would increase the tensile strength of Lou’s underlayment, but appears instead only to fault Mr. Kaczkowski for not determining whether those solutions would be less expensive than other alternatives. Such arguments are not persuasive. Although, as cited above, Petitioner alleges in the Petition that a skilled artisan would have recognized cross-lamination as “a simpler, less costly way to manufacture a nonwoven reinforcing scrim . . . consistent with Lou” (Pet. 37), we find that is only one among several reasons identified by Petitioner and Mr. Kaczkowski for the combination (see, e.g., id. at 34–35 (additionally identifying increased tensile strength as a well-known benefit of orienting polyolefin fabric)), each of which is independently persuasive.” slip op. at 53

Federal Rule of Evidence 801 defines “hearsay” as a “a statement that: (1) the declarant does not make while testifying in the current trial or hearing; and (2) a party offers in evidence to prove the truth of the matter asserted in the statement.” Fed. R. Evid. 801(c). We agree with Petitioner that Patent Owner is offering Dr. Reitman’s testimony for its truth. As Petitioner points out, Dr. Reitman’s testimony is presented in the Patent Owner Response in alleged support of Patent Owner’s argument. See Reply Mot. Excl. 1 (citing PO Resp. 22 (“Maureen Reitman recognized that ‘extrusion coating’ and ‘extrusion lamination’ were two different processes”; “[A]s Ds. [sic] Reitman recognized, a POSITA would understand ‘extrusion coating’ to be different than ‘extrusion lamination.’”)). Further, Rule 802 provides that hearsay is not admissible unless a federal statute, the Federal Rules of Evidence, or other rules prescribed by the Supreme Court provide otherwise. Fed. R. Evid. 802. We agree with Petitioner that no exception or exclusion applies in this case. Mot. Excl. 1. Although, as Patent Owner contends, Federal Rule of Evidence 703 provides that “[a]n expert may base an opinion on facts or data in the case that the expert has been made aware of or personally observed,” and that “[i]f experts in the particular field would reasonably rely on those kinds of facts or data in forming an opinion on the subject, they need not be admissible for the opinion to be admitted,” we are not persuaded that opinions of others offered in litigation are the sort of “facts or data” that experts in the field of roofing underlayments would reasonably rely on in forming their own opinions.” slip op. at 64

“phrase “means for . . . .” Petitioner construes these terms in accordance with 35 U.S.C. § 112 ¶ 6, identifying an algorithm described in the specification corresponding to each “means” limitation. Pet. 7–9 (citing Ex. 1001, col. 8, l. 8–38, col. 8, ll. 49–col. 9, l. 16, col. 19, l. 25–col. 20, l. 67). Petitioner identifies a general purpose computer, processor 704 in Figure 7, as structure for “executing the instructions associated with the corresponding function” recited in each “means limitation,” except for the “means fro [sic] the first participant to communicate . . .” recited in claims 5 and 20. Pet. 7–9 (citing Ex. 1001, Fig. 7, col. 25, ll. 13–18). For the “means fro [sic] the first participant to communicate” limitation, Petitioner identifies transceiver 216, shown in Figure 2, reproduced supra. Pet. 9 (citing Ex. 1001, Fig. 2, col. 9, ll. 54–59). Patent Owner does not contest these identifications. We agree with Petitioner’s identifications and adopt them as our constructions of the means-plus-function limitations. Specifically, as to those means-plus-function limitations that correspond to processor 704 in Figure 7, Petitioner identifies in its claim chart the algorithm described in the specification for performing each function of these means. Pet. 8–9; See also Function Media, L.L.C. v. Google, Inc., 708 F.3d 1310, 1318 (Fed. Cir. 2013) (“When dealing with a ‘special purpose computer-implemented means-plus-function limitation,’ [the Federal Circuit] require[s] the specification to disclose the algorithm for performing the function.”); Blackboard, Inc. v.

- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed petitioner constructionDecided for petitioner
“We are not persuaded by this reasoning. As Petitioner observes, the embodiments of the ’624 patent identified by Patent Owner are characterized as “examples,” and a person of ordinary skill “would understand that the example scenarios of the specification are not necessarily limiting on the claims.” Reply 3 (citing Ding Supp. Decl. ¶ 6). In addition, Petitioner notes that claim language in related patents owned by Patent Owner explicitly refers to participants, evidencing Patent Owner’s understanding “how to expressly create participant-specific voting requirements in claims.” Id. at 3. At the oral hearing, Patent Owner suggested that explicit reference to participants in such other claim language “was because it wanted to clarify that each participant got a single vote,” and explained its position that, in the claims at issue in this proceeding, “participant is implicit in the claim language as it is.” Tr. 78:16–25. But the claims are directed to a “communications apparatus,” and recite “votes” in the context of what the “particular communications channel” “receives.” Nothing within the structure of the claims requires resolving the origin of such votes. Furthermore, Patent Owner’s proposed construction is inconsistent with the construction it agreed to before the district court in the Qualcomm Litigation. In that litigation, the parties agreed that the term “vote” should be construed as “a binary expression (to use or not to use),” a construction that makes no reference to the origin of the “vote” as from a participant or otherwise. Ex. 1014, 6. We see no compelling reason to excuse the inconsistency by adopting a narrower construction when the Board applies a claim-construction standard (broadest reasonable interpretation) that could only result in the same or a broader construction. See Amazon.com, Inc. v. Barnesandnoble.com, Inc., 239 F.3d 1343, 1351 (Fed. Cir. 2001) (“A patent may not, like a ‘nose of wax,’ be twisted one way to avoid anticipation and another to find infringement.” (quoting Sterner Lighting, Inc. v. Allied Elec. Supply, Inc., 431 F.2d 539, 544 (5th Cir. 1970))). Accordingly, we construe “votes to use a particular communications channel” as “expressions of preference for using the particular communications channel.”” slip op. at 10

“Patent Owner responds that “the Gerten device is not capable of and expressly teaches away from performing this functionality.” PO Resp. 15 (citing Melendez Decl. ¶ 33). Patent Owner contends that “Gerten’s disclosure is directed toward eliminating channels for use in an entire piconet as opposed to eliminating channels for use by certain participants within a piconet.” Id. at 16 (emphasis added). Patent Owner argues that Gerten does not disclose a selection kernel capable of maintaining synchronization between a master and more than one slave in a piconet, with the master and one slave using a default set of channels while the same master and a different slave use a different set of channels. Id. We are not persuaded that the absence of a specific teaching of such a selection kernel supports the conclusion that one of skill in the art would understand Gerten to function in the manner Patent Owner suggests. In this instance, Petitioner refers to two embodiments of Gerten “in which a first participant communicates with a second participant via a normal sequence and with another participant via an adaptive hopping sequence.” Reply 5. First, Figure 3 of Gerten is reproduced below. Figure 3 illustrates “methodology for determining and communicating channels to be avoided to a remote device.” Ex. 1003, col. 2, ll. 4–6. As illustrated in the drawing, a master unit performs a discovery process (block 110) upon connecting with a new slave unit. Ding Decl. ¶¶ 60, 64. If the slave unit is capable of using interference avoidance, the master unit begins the process of determining a modified set of channels for use (block 120). Id. ¶ 45. If a second slave unable to use interference avoidance enters the piconet, standard frequency hopping is used. Supp. Ding Decl. ¶ 9. Under Patent Owner’s characterization of Gerten, entry of the second slave into the network would require the first slave necessarily to revert back to the default hopping sequence. Id. ¶ 10. But this would undermine the stated benefits of Gerten, which explicitly discloses: The above process can be applied to a Bluetooth example and includes identification of a Bluetooth device’s ability to support interference avoidance, the measurements of signal strength on all channels and identification of which channel should not be used without violating the FCC rules, a method of modifying the Bluetooth hop sequence so that it will avoid channels containing strong or fixed interferers while still supporting standard Bluetooth hopping with other non-enabled members of the piconet and a method of relating necessary interference avoidance information to the remote Bluetooth devices.
