      “This disclosure is inconsistent with any suggestion that the Fangman system, when routing a telephone call to its destination, identifies the private IP address of the destination telephone by determining the port range to which the port number of the destination telephone belongs. When Fangman describes the NAPPT process, it does not indicate that port ranges are used, but rather repeatedly states that port numbers are used: The [service gateway] receives a data packet from the IP device, including a public destination IP address . . . a destination port number . . . and source information, NAPPTs the data packet, using the [public destination IP address] and the [destination port number] to identify the [IP telephone] . . . . Ex. 1024, code (57). Performing NAPPT on the data packet received from the destination may include using the public destination IP address and the destination port number to uniquely identify the IP telephone, and changing the public destination IP address to a private source IP address of the IP telephone while leaving the destination port number unchanged.

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for petitioner

      “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.

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundUnpatentable

      “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

      “Dr. Durand testifies that “a POSITA would have understood that Martin’s teachings of critical alignment for stable transition between images of different points of view apply to electronic camera systems providing continuous zoom video output [i]mages as taught in Golan, regardless of whether a three dimensional illusion is provided.” Ex. 1003 ¶ 59. Citing Ahiska (Ex. 1007), Border (Ex. 1009), Orimoto (Ex. 1014), and Hansen (Ex. 1019) to support his testimony, Durand further testifies that It was well known in the art that for seamless transition between two images of different points of views in continuous zoom video applications, when calibration between two cameras (e.g., the electronic calibration of Golan) is not sufficient alone (e.g., because of shocking, vibration, thermal variation, etc.), image registration of two images from two imaging sections for position matching (e.g., critical alignment of Martin) may be used. Id. ¶ 57 (citing Ex. 1007, 4:58–62, 10:2–5; Ex. 1014, 1:63–2:1; Ex. 1019, 1059; Ex. 1009 ¶¶ 41, 42). The portion of Hansen (Ex. 1019) cited by Dr. Durand addresses how extrinsic calibration errors occur and “a method to recalibrate extrinsic parameters online to correct drift or bias.” Ex. 1019, 1059 (emphasis omitted). Orimoto discloses how misalignment occurs, irrespective of “how exactly the dual lens camera has been conditioned and adjusted by the manufacturer.” Ex. 1014, 1:63–2:1. Border addresses image registration as an alternative to correspondence (i.e., calibration). Ex. 1009 ¶¶ 41, 42. And Ahiska disclose image registration or matching, when calibration is insufficient, to provide a seamless transition between master and slave cameras and “create the quality of a continuous zoom function.” Ex. 1007, 4:58–62, 10:2–5 (“[i]f calibration between the [wide-angle] master and slave cameras is insufficient alone, image registration or matching can be carried out,” “transition[ing] between the master view and the slave view as seamlessly as possible to create the quality of a continuous zoom function”). Petitioner’s third and fourth reasons for combining Golan and Martin are supported by Dr. Durand’s testimony quoted above, which is in turn supported by Ahiska and Border. The portions of Border cited by Dr. Durand address image registration as an alternative to correspondence (i.e., calibration). Ex. 1009 ¶¶ 41, 42. The portions of Ahiska cited by Dr. Durand address the additional step of image registration or matching, when calibration is insufficient, to provide a seamless transition between master and slave cameras and “create the quality of a continuous zoom function.” Ex. 1007, 4:58–62, 10:2–5. Thus, each of Border and Ahiska show a relation between electronic calibration and registration.

We also agree with Petitioner that Krtolica discloses the use of HTTP protocols on port 80 (Ex. 1004, 6:23–24), and does so with a goal of maintaining high network security (id. at 1:7–10, 2:33–36). As Kirchhoff discloses, and Dr. Lavian’s testimony supports, one of ordinary skill in the art would have been aware that port 443, rather than port 80, would be used for secure web connections using SSL, which includes the use of encryption, and this would have resulted in enhanced network security. See Ex. 1005, 3:38–41; Ex. 1002 ¶¶ 52, 69, 108. As Dr. Lavian testifies, SSL/TLS was the most widely deployed security protocol in the world and the well-known use of SSL in HTTPS protocol enables secure web-based e-commerce. Ex. 1002 ¶¶ 69, 108; Ex. 1035 ¶ 8; Ex. 1006, 5. And, Krtolica has a stated goal to maintain network security. Ex. 1004, 1:7–10, 2:33–37. We find this evidence provides a sufficient rational underpinning in support of obviousness for combining the teachings of Krtolica and Kirchhoff. See KSR, 550 U.S. at 418. Owner’s arguments that use of encryption in SSL was optional and adding encryption would allegedly undermine network security. Nor do we find persuasive the argument that the Petitioner’s motivation to combine based on efficiency is insufficient, because Petitioner relies on another rationale for the combination of Krtolica and Kirchhoff, that is, enhanced network security, also discussed above. We additionally do not find persuasive Patent Owner’s arguments that combining Krtolica and Kirchhoff would render the system of Krtolica unsatisfactory for its intended purpose because, as Petitioner argues, this assertion is contradicted by the state of the art at the time. See Pet. Reply 9. As discussed above, Dr. Lavian explains that there were known systems having firewalls with SSL traversal at the time of the invention. Ex. 1002 ¶¶ 53, 59–65; Ex. 1035 ¶ 20; Ex. 1014. Moreover, the ’978 patent uses encryption with firewalls using a single-port protocol, and Patent Owner does not direct us to any disclosure in that patent that indicates that the use of encryption with a single-port protocol was inventive in that the system, or that encryption had to be done in a special manner.

Holdings, summaries, rulings, issues, outcomes, winners and claim constructions shown for a decision were generated by a large language model reading the opinion. They are a guide to the decision, not the decision. Confirm every one against the court's own text before relying on it. Outcomes read from the patent owner’s side. Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
