“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

“the “reinforcing scrim of interwoven strands” recited in claim 1 and Lou’s polypropylene polymer 2 to the recited “thermoplastic material.” Id. at 22– 23. Petitioner further contends that Lou discloses “affixing the thermoplastic material by extrusion lamination,” citing Lou’s disclosures that “[e]xtruder 20 supplies polypropylene polymer 2 through a slit orifice to deposit a thin continuous coating on the surface of sheet 1” and that coated sheet 3 is pressed by a calendaring nip formed by heated and unheated rolls. Id. at 23 (quoting Ex. 1005, 2:34–44) (citing Ex. 1003 ¶ 19; Ex. 1005, 2:45– 49).” slip op. at 34

“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

“Motion to Exclude. 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
