“In its Response, InterDigital does not contest Dr. Acampora’s articulation of the level of ordinary skill, except that “InterDigital applies Petitioners’ alleged baseline level of ordinary skill without the phrase ‘at least.’” PO Resp. 3. We agree with InterDigital that the term at least arguably “creates unnecessary ambiguity.” Id. (citing Inst. Dec. 9–10). But we find that Petitioner’s articulation, after deleting the phrase at least, is reasonable in light of the subject matter involved in the ’449 patent, and we adopt it for our decision.” slip op. at 10

“To the extent that text was copied and pasted in either direction between the Petition and Dr. Acampora’s declaration, we disagree that this mere fact indicates that we should give Dr. Acampora’s testimony less weight. Patent Owner does not argue that Dr. Acampora was uninvolved with the preparation of his declaration, which he signed, under penalty of perjury, and presented as reflecting his own opinions. That typographical errors may, for example, have been propagated from his declaration to the Petition is by itself of little consequence. The cited Wowza decision does not suggest otherwise. In that case, the Board assigned little weight to the expert declaration, not because of its similarity to the petition, but because the declaration did not disclose the underlying facts or data on which its opinion testimony was based. See IPR2013-00054, Paper 16 at 4–5. As Petitioner correctly argues in its Reply, InterDigital does not “identif[y] where Dr. Acampora fails to provide sufficient facts underlying his opinions.” Pet.

“1. “channel quality” InterDigital states that the court in the parallel district court litigation adopted the parties’ agreed construction of “channel quality” as meaning “a value/values quantifying how efficiently downlink resources of a channel can communicate information.” PO Resp. 3–4 (citing Ex. 2008, 1; Ex. 2009, 18). InterDigital contends that the ’449 patent suggests this construction, and that both sides’ experts agree with it.

“Although Patent Owner contends Dr. Goodnick’s declaration did not open the door for general questioning about metal oxides (PO Opp. 2–3), we agree with Petitioner that the proper scope of cross examination includes Dr. Goodnick’s understanding of what constitutes a distinct layer. A primary issue raised by Patent Owner against Petitioner’s challenge that Goodnick anticipates is that, notwithstanding its use of the term layer, Goodnick does not teach distinct layers that are required by the claim. See Section VI.B. One of those layers is a metal oxide layer (Ex. 1101, claim 1), in particular a titanium oxide layer (claim 6). In view of Dr. Goodnick’s checkerboard analogy in his declaration, it was proper for Petitioner to question Dr. Goodnick about the extent of materials in the checkerboard. Both parties argue there may be implications of Dr. Goodnick’s testimony for purposes of infringement litigation. See Pet. Opp. 4–6; PO Reply 3–4. We do not address those implications. The issue before us is whether Goodnick would have taught or suggested to a person of ordinary skill the limitations of the claims, which the parties agree include distinct layers of metal oxide and other semiconductor oxide. See Section VI.B. As Dr. Goodnick testified that his article did not teach such distinct layers, it was proper for Petitioner to explore Dr. Goodnick’s views concerning the composition of a layer during cross examination. In consideration of the above, Patent Owner’s motion to exclude the Goodnick Metal Oxide testimony is denied.” slip op. at 48

“that “the semiconductor region comprises an n-typed doped source or drain of a transistor.” Acknowledging that Goodnick “does not expressly disclose that its n-doped silicon semiconductor region ‘comprises an n-type source or drain of a transistor,’” Petitioner cites Jammy as disclosing this feature. Pet. 27. According to Petitioner, a person of ordinary skill would have combined the teachings of Goodnick and Jammy because Goodnick describes contact metallization processes for semiconductor devices and Jammy describes a semiconductor device. Id. at 28. Patent Owner asserts that Petitioner’s challenge to claim 4 based on the combined teachings of Goodnick and Jammy fails because it is premised on Goodnick teaching a stratified layer of Al2O3 distinct from SiO2. PO Resp. 60. As discussed above, we find that a person of ordinary skill would have understood Goodnick to disclose this feature. See Section VI.B. In consideration of the above, we find that Petitioner has demonstrated by a preponderance of the evidence that a person of ordinary skill would have had reason to combine the teachings of Goodnick and Jammy and that the combined teachings of Goodnick and Jammy would have suggested the limitations of claim 4 to a person of ordinary skill in the art.” slip op. at 24

“b. Analysis We adopt Petitioner’s proposed construction for advertising break: “a break in the program content (the ‘Internet radio stream’) where advertising content was or can be inserted.” Reply 2. The Specification and challenged claims support Petitioner’s proposed construction. First, both parties agree that an advertising break is a type of program break. PO Resp. 14; Reply 2. Although the Specification does not expressly define the term “program break,” the Specification uses the term to refer to a break during which content which is distinct from a program was or can be inserted. For example, the Specification discloses that audio programs in an Internet radio stream “will normally include program breaks during which audio content that is distinct from the program content is delivered.” Ex. 1001, 1:34–36 (emphasis added). The Specification further describes that the “present invention seamlessly selects content for outputting on a mobile device during a program break in an Internet radio stream using mobile device location information and program break markers.” Id. at 1:64–67 (emphasis added). The Specification has additional disclosures of selecting non-program content for insertion in a program break.

“ii. Analysis We agree with Petitioner that an ordinarily skilled artisan would have been motivated to combine Rittmaster’s and Duvall’s teachings, would have had a reasonable expectation of success in making that combination, and would not, as Patent Owner argued, have had to substantially reconstruct and redesign Rittmaster to do so. We credit Mr. Wechselberger’s testimony that an ordinarily skilled artisan would have been motivated to combine the teachings of Rittmaster and Duvall with a reasonable expectation of success. Ex. 1011 ¶¶ 46–50. As Mr. Wechselberger explains, Duvall provides the details of how to select an advertisement from the stored advertisements using a duration indicator combined with other factors, such as location. Ex. 1011 ¶¶ 46, 50; Ex. 1008, 8–9, 24. Because Rittmaster’s similar system also selects advertisements based on the user’s location and other criteria to provide advertisements that fit the programming break, an ordinarily skilled artisan would have expected Duvall’s teachings to work in Rittmaster’s system. Ex. 1011 ¶ 50; Ex. 1007 ¶ 132. Duvall provides further details on how to select content that fits the programming breaks, as suggested by Rittmaster. Ex. 1011 ¶¶ 46, 50; Ex. 1008, 8–9, 24. Duvall discloses how to add or implement a variable duration indicator to a system for providing targeted content to users, like the system of Rittmaster. Ex. 1011 ¶¶ 46, 50; Ex. 1008, 8–9, 24. And an ordinarily skilled artisan would have had a reasonable expectation of success in applying Duvall’s teachings to Rittmaster’s system because Duvall uses local storage of the advertising options in its client-side system in a manner similar to the storage of advertisements in the server-side system of Rittmaster.

We do not credit Dr. Rhyne’s testimony that combining the teachings of Rittmaster and Duvall would have required a substantial redesign of Rittmaster. Ex. 2002 ¶¶ 90–92.11 Regarding this issue, Dr. Rhyne testifies: 11 In paragraph 90, Dr. Rhyne refers to the substantial reconstruction of Estese, but the reference to Estese appears to be a typographical error. This section of his declaration addresses the combination of Rittmaster and Duvall. Rittmaster would require fundamental reconstruction to incorporate Duvall’s content identification list information 122 because Duvall’s content identification list information 122 only identifies advertisement data already embedded in a data stream. Rittmaster teaches using time frames during which content such as an advertisement may be inserted. See Rittmaster at [0132]; Ex. 2001 at 33, lines 20–24. Like Estese, Rittmaster is a system where time frames or windows allow customization by interleaving location-based advertisements into the frame before delivering it to the recipient. Rittmaster at [0132]. To use Duvall’s content identification list information 122, which identifies advertisement spots that are already part of a media stream, would thus require replacing the frame structure of Rittmaster with a full media stream that could then be overwritten—or in the terminology of Duvall, “muted”—in specific locations when told to by content identification list information 122.” slip op. at 34

“As discussed above, we agree with Petitioner that Kirchhoff discloses the use of SSL, a protocol that uses data encryption (Ex. 1005, 8:47–49). 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. See Pet. Reply 3 (citing Ex. 1001, Fig. 3 (at 311, 341), Fig. 5 (503, 508)); see also Ex. 1001, 6:4–8. In a similar vein, Patent Owner argues that due to incompatibilities the combination of SSL with Krtolica would be unsuccessful, and we address this issue below.” slip op. at 30

“Petitioner’s proposed construction for “articulating link.” In this proceeding, we construe a claim term to have its broadest reasonable construction. Petitioner’s proposed construction, which is broader than Patent Owner’s proposal, is reasonable in light of the Specification. The only non-testimonial evidence in the record for the ordinary meanings of the terms “articulating” and “link” are the dictionary definitions provided by Petitioner (Ex. 1012, 1015), and those dictionary definitions support Petitioner’s proposed construction. The 1999 edition of the Chambers Dictionary of Science and Technology provides an engineering definition for “articulation,” which is “[t]he connection of two parts in such a way (usually by a pin joint) as to permit relative movement.” Ex. 1015. The 2004 edition of the Merriam-Webster Dictionary defines “link” as “a connecting structure.” Ex. 1012. Mr. Boos testifies, and we agree, that these definitions are evidence that an ordinarily skilled artisan would have understood the ordinary meaning of “articulating link” to be “a connecting structure that connects two parts in such a way as to permit relative movement.” Ex. 1009 ¶ 9. Further, Petitioner’s proposed construction is consistent with the disclosure of an articulating link in the Specification, which describes articulating link 31 as connecting blast head 23 and tractor 20, and permitting relative movement between those parts. Ex. 1001, 4:11–14 (“horizontal movement” and “vertical movement”). In addition, we determine that Patent Owner’s proposed construction is not a reasonable construction in light of the Specification. Neither Patent Owner nor Dr. King directs us to any portion of the Specification that expressly defines the term “articulating link.” Instead, the cited portions of the Specification describe what one exemplary articulating link, link 31, does. For example, a cited portion of the Specification describes that articulating link 31 is capable of horizontal and vertical movement and has a rotatable connection with arms 37, 38, 44, and 45. Ex. 1001, 4:11–43 (cited by Ex. 2012 ¶ 40). Nowhere does the Specification, however, indicate that all articulating links must have such a capacity and such a connection. See id. Instead, the Specification merely discloses that this particular exemplary articulating link has these features. Id.

“We do not need to provide a different construction because Patent Owner does not dispute that NLB discloses a cleaning system. Therefore, any dispute between the parties that could exist regarding the meaning of the term “cleaning system” is not material to any patentability issue we need to decide. 3. Disputes that Concern Only Petitioner’s Alternative Arguments The parties propose differing constructions for the terms “hard surface,” “high pressure,” “blast head,” “coatings,” and “high power vacuum pump.” Compare Pet. 13–17, with PO Resp. 7–9. The differences in the parties’ constructions for these terms are material only to Petitioner’s alternative arguments that the asserted references without NLB would disclose the recited “hard surface,” “high pressure,” “blast head,” “coatings,” and “high power vacuum pump.” Because we do not need to address those alternative arguments in this Decision, we do not need to construe these terms, as we explain in more detail below. First, Petitioner proposes construing “hard surface,” recited in claims 1 and 4, as “any surface having rigidity sufficient to support the weight of a vehicle carrying the blast head.” Pet. 13. Patent Owner proposes construing the term as “the surface of a material that is hard enough to withstand high-pressure water blasting without disintegrating, for instance paving material in common use for road, parking lot, and airport runway surfaces such as asphalt or concrete.” PO Resp. 8–9. The differences between these proposed claim constructions are material only to Petitioner’s alternative arguments that the asserted references without NLB would disclose a hard surface. Under both parties’ constructions, NLB’s roads, concrete, and asphalt are “hard surfaces,” which neither party has disputed. Ex. 1006, 2.

“After evaluating the parties’ arguments and evidence, we agree with Patent Owner that Mr. Boos is an interested witness because of his positions with and his equity stake in Petitioner, and in evaluating his testimony, we consider his status as an interested witness in determining the probative weight of his opinions. For example, when Mr. Boos’s testimony is not sufficiently corroborated by objective evidence, we attribute little or no weight to his testimony due to that interest. When Mr. Boos’s testimony is sufficiently corroborated by objective evidence, however, we do not so discount his testimony. We do not agree with Petitioner’s suggestion that Patent Owner had to prove that Mr. Boos’s interest influenced his testimony for us to take into account that interest. Patent Owner established Mr. Boos’s interest. Therefore, we consider that interest when evaluating Mr. Boos’s testimony. Ethicon, 135 F.3d at 1465. We are not persuaded by Patent Owner’s other arguments for discounting Mr. Boos’s testimony. First, we do not read the testimony of Mr. Boos cited by Patent Owner as demonstrating that Petitioner’s attorneys, rather than Mr. Boos, were responsible for the technical opinions provided in his declarations.
