“b) Person of Ordinary Skill in the Art Petitioner contends a person having ordinary skill in the art pertaining to the ’732 patent would have either: “(1) a Bachelor of Science in Mechanical Engineering, Electrical Engineering, Petroleum Engineering or an equivalent field as well as at least two years of academic or industry experience in the oil and gas industry, including well drilling, completion, or production”; or “(2) at least four years of industry experience in the oil and gas industry, including well drilling, completion, or production.” Pet. 13.

“witnesses cannot agree on a numerical definition of “high pressure.” Mr. Marscher says high pressure is between 5,000 psi and 15,000 psi (see Ex. 1030, 111:1–112:3), whereas Mr. Schaaf says high pressure is between 8,000 psi and 12,000 psi and specifically disagrees with Mr. Marscher’s testimony that high pressure can be below 8,000 psi (see Ex. 1031, 43:6–44:13). Although there are overlapping values in the witness testimony, we agree with Petitioner that the testimony does not evidence clear boundaries for how an ordinarily skilled artisan would interpret “high pressure.” See Mot. Sur-reply 6 (citing Nautilus, Inc. v. Biosig Instruments, Inc., 572 U.S. 898, 901–02 (2014); Interval Licensing, 766 F.3d at 1371). Thus, the testimony of Patent Owner’s own witnesses is contrary to Patent Owner’s position that an ordinarily skilled artisan would have understood the meaning of “high pressure.” Furthermore, neither Mr. Marscher nor Mr. Schaaf cites any objective evidence to support their respective notions of what “high pressure” might be, in the context of hydraulic fracturing. For example, neither witness cites to any published industry standards to support their respective opinions. This lack of objective evidentiary support weakens the persuasiveness of both witness’s testimony on this issue, especially because their opinions conflict with each other. We are instead persuaded by the testimony of Petitioner’s witness, Dr. Durham, who testifies that “[t]here is [no] general consensus about the precise boundaries of the term ‘high pressure,’ and different engineers can reasonably come to different conclusions as to the meaning of the term absent further guideposts.” Ex. 1036 ¶ 17; see also id. ¶ 19 (“There is no universally accepted definition of ‘high pressure.’”). Dr. Durham further testifies that “what might be sufficiently ‘high’ pressure for one fracturing application and according to one [person of ordinary skill in the art] may be not ‘high’ enough in another fracturing application and to another [such person].” Id. ¶ 18; see also id. ¶ 19 (“Merely stating that a pump fractures a formation says little to nothing about whether that pump should be deemed ‘high pressure’ or ‘not high pressure.’”).” slip op. at 30

“The intrinsic record does not “provide objective boundaries for those of skill in the art” to determine whether a given pressure is “high pressure” as recited in the proposed substitute claims. See Interval Licensing, 766 F.3d at 1370–71. Nor does the intrinsic record provide guidance to clarify the meaning of “high pressure.” As noted above, the ’732 patent refers only to “high pressure” without qualification or explanation as to how “high pressure” is determined. The prosecution history does not address “high pressure” in any meaningful way and, therefore, also fails to explain what pressures are “high” pressures. See generally Ex. 1003. Thus, the intrinsic record does not explain adequately what pressure(s) qualify as “high pressure,” nor differentiate “high pressure” from other pressures at which hydraulic fracturing can be performed.” slip op. at 27

It could simply mean that data being transmitted by itself is not a radio resource, but the RF carrier transmitting the data could be a radio resource.

“skilled artisan to have its “ordinary and customary meaning[],” allegedly “a stream of data bytes that can be read and written (among other common operations).” PO Resp. 3. But as noted by Petitioner (Pet. Reply 3–4), the only intrinsic evidence cited by Patent Owner does not support its proposed construction in the context of the ’613 patent; rather, such evidence favors Petitioner. See PO Resp. 4 (citing Ex. 1001, 2:35–45 (a “‘file is accessed via the file descriptor’”), 2:46–3:7 (“‘the system calls that access files via file descriptors do not distinguish between a file on media and a communication channel’”)); see also PO Resp. 7 (“It is undisputed that file descriptors were conventionally ‘associated with’ files stored on media, communication channels, and even hardware devices.” (emphasis added)). Patent Owner also cites extrinsic evidence, namely, Dunsmuir (Ex. 1007), to support its proposed construction: “Conceptually, a file consists of a stream of data bytes followed by a logical end-of-file. … Because UNIX file I/O is performed through a uniform file interface, a program that can read and write files can read and write anything.” PO Resp. 4 (quoting Ex. 1007, 22). But as noted by Petitioner (Pet. Reply 4–6), Patent Owner does not explain why this “conceptual” meaning set forth in the generic context of programming interfaces in a UNIX operating system would apply in the specific context of the ’613 patent. See Pet. Reply 4 (“[Patent Owner’s] proposed construction is problematic because it is inconsistent with the specification of the ’613 patent.”). Patent Owner also does not explain what “among other common operations” means in the context of its own proposed construction. For the foregoing reasons, and those discussed below, we agree with Petitioner’s proposed construction of “file.” First, the claims of the ’613 patent support Petitioner’s proposed construction. For example, claim 1 recites that a “file” is accessed via a file descriptor. Ex. 1001, 14:55. Claim 5 recites a file descriptor being associated with “a communication channel” and determining with what file type the file descriptor is associated. Ex. 1001, 15:44–57. Together, these limitations show that a “file” is an entity assessed via a file descriptor, and such an entity includes, for example, a communication channel (i.e., per these claims, a communication channel is a type of file associated with a file descriptor). We find nothing in the claims, and Patent Owner does not direct us to anything in the claims, that supports limiting the term “file” only to a “stream of data bytes that can be read and written.”” slip op. at 20

“In our Institution Decision, we credited the foregoing and related testimony of Dr. Greenspun (Ex. 1002 ¶¶ 96–98), and noted that Patent Owner at that stage of the proceeding had not offered any evidence to rebut Dr. Greenspun’s testimony. Dec. 30–31. Despite that, as highlighted by Petitioner, Patent Owner still offers no evidence to rebut Dr. Greenspun’s testimony in this regard. See Pet. Reply 16 (“But in arguing all these [above arguments], [Petitioner] presents no rebuttal evidence—neither a deposition testimony of Dr. Greenspun, nor a rebuttal testimony by its own expert, nor any other evidence.”); see generally PO Resp. Instead, Patent Owner merely declares Dr. Greenspun’s testimony “conclusory” and tainted by “vague leap[s]” (see, e.g., PO Resp. 14), but yet makes such accusations against a technical declarant with nothing but attorney-argument. Regardless, for the same reasons given by Petitioner (see Pet. Reply 16–18), we disagree with Patent Owner and continue to credit Dr. Greenspun’s technical testimony as to the subject limitation. See Pet. Reply 16–18 (Petitioner explaining why “[Patent Owner’s] attorney argument is wrong”.). As noted above, Patent Owner variously argues Dukach does not disclose “storing” of the indicator at issue in this limitation. See generally PO Resp. 7–17. To summarize, we disagree with Patent Owner, and as explained above, are persuaded by Petitioner’s evidence, including the unrebutted testimony of Dr. Greenspun, that Dukach discloses storing information that points to a file type associated with a file descriptor. First, we are persuaded that, in Dukach, the presence or absence of a file descriptor’s number in the list of monitored file descriptors constitutes information that points to a file type associated with the file descriptor. See Pet. 37–40 (citing, inter alia, Ex. 1005, 11:5–40; Ex. 1002 ¶ 96; Ex. 1001, 11:12–42). Second, we also are persuaded that, in Dukach, the list of monitored file descriptors “needs to be maintained in memory such that it can be used by software to check an at-issue file descriptor’s presence or absence in the list,” which constitutes storing the indicator. Pet. Reply 16– 17 (quoting Ex. 1002 ¶ 97); see Pet. 40 (citing Ex. 1002 ¶ 97). Finally, even if Patent Owner were correct that Dukach does not disclose a particular embodiment in the ’613 patent (see, e.g., PO Resp. 15 (discussing an embodiment “only applicable for binary file types”)), the issue before us is not whether Dukach indeed discloses such an embodiment, but rather whether Dukach discloses the invention recited, for example, in claim 1, given the breadth (scope) of the limitations defining that invention.” slip op. at 37

Patent Owner states that it “accepts that definition for the purposes of this proceeding.” Rev’d MTA 24. Mr. Fischer’s definition is consistent with the level of ordinary skill reflected in the prior art references of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

“Petitioner proposes constructions for “code” and “Electronic Product Code (EPC).” Opp. to Rev’d MTA 6. Patent Owner asserts that “the limitations of the substitute claims do not require construction and should, instead, be construed in accordance with their ordinary meaning.” Rev’d MTA 24. According to Patent Owner, the addition of certain features of the proposed substitute claims renders moot Petitioner’s arguments concerning the meaning of the term “code.” Id. Additionally, Petitioner argues that the content of the recited codes— an EPC and a code different from the EPC—constitutes “printed matter” (non-functional descriptive material) and, therefore, are not entitled to patentable weight. Opp. to Rev’d MTA 7–10; Pet. Sur-reply 5–6. We need not reach this issue. Even if we construed the specifically recited codes as being non-functional descriptive material, Petitioner, for reasons discussed below, has not shown that the claimed subject matter is unpatentable. Also, the parties do not identify any other issue in this case that turns on whether the two recited codes are non-functional descriptive material. See, e.g., Opp. to Rev’d MTA 11–12 (Petitioner arguing that the relied-on prior art discloses codes in the form of an EPC and a TID (i.e. a code other than the EPC)). On this record, we determine that no claim terms require express construction.” slip op. at 14

- ScopeDecided for patent owner
“Motion to Amend, that “[c]onstruing ‘a first and second memory bank’ to mean, for example, two memories instead of ‘a memory’ also impermissibly broadens the claims.” Opp. to Rev’d MTA 4 n.1 (citing Ex. 1032 ¶¶ 3024– 3027); see also Pet. Sur-reply 1–2 (“the scope of the proposed claims is impermissibly broadened to encompass logical memory banks storing codes in more than one memory.”); Tr. 7:12–13 (“That’s improper because it enlarges the scope of claims to include two memories instead of just one.”). Petitioner’s argument appears to assume that the proposed substitute claims require two memories (as opposed to the recited “memory bank[s]”) and that, because two memories are quantitatively more than one memory, the claims have been broadened. We disagree with Petitioner’s arguments. The arguments are contingent upon a construction of two memory banks being the same scope as two memories. See Opp. to Rev’d MTA 4 n.1 (“Construing . . . impermissibly broadens the claims.”). Petitioner has not offered any persuasive argument or evidence that the two different terms—“memory” and “memory bank” are coextensive or that the more general term “memory” can encompass two of the more specific “memory bank[s].” Further, even if the proposed substitute claims required two memories rather than two memory banks, adding the requirement of a second memory (or, as written in the proposed claims, two memory banks rather than “a memory” as in the issued claim) is further limiting the claims and, therefore, is not broadening the scope. See Hockerson-Halberstadt, Inc., 183 F.3d at 1374. We agree with Patent Owner that the amended language regarding two memory banks does not impermissibly broaden the scope relative to the original claims.” slip op. at 18

“Turning now to obviousness, Petitioner identified disclosure within Kurgonov-262 and Chakrabarti which teaches or suggests the limitations of claim 1. Pet. 11–21. Furthermore, Petitioner identified multiple reasons that would have prompted the skilled artisan to combine the teachings of Kurganov-262 and Chakrabarti to arrive at the subject matter of claim 1. Id. at 21–22. Because Patent Owner focused its arguments solely on the issue of whether Kurganov-262 is prior art, Petitioner’s assertions regarding the substantive teachings of Kurganov-262 and Chakrabarti remain unrebutted on the complete record. PO Resp. 31–34; Sur-reply 1–3. Patent Owner likewise failed to substantively address Petitioner’s proffered reasons why the skilled artisan would have been motivated to combine these teachings. PO Resp. 31–34; Sur-reply 1–3. We have reviewed the disclosures of Kurganov-262 and Chakrabarti relied on by Petitioner, as well as the explanations provided by Mr. Lipoff, and are persuaded that the limitations of claim 1 are disclosed in the prior art. Pet. 11–21; Ex. 1002 ¶¶ 103–109; Ex. 1004; Ex. 1008. Petitioner also persuades us that the skilled artisan would have been motivated to apply Chakrabarti’s techniques for web crawling to Kurganov-262’s system, and would have had a reasonable expectation of successfully doing so, thus arriving at the subject matter of claim 1 of the ʼ084 patent. Pet. 21–23; Ex. 1002 ¶¶ 110–114. Therefore, Petitioner has shown, by a preponderance of the evidence, that the subject matter of claim 1 of the ʼ084 patent would have been obvious over the combined disclosures of Kurganov-262 and Chakrabarti.” slip op. at 24

“Petitioner describes a person having ordinary skill in the art as having “a Bachelor’s degree in electrical engineering, computer science or a related field, and at least two years of experience with voice interfaces and information processing. More education could substitute for less experience, and vice versa.” Pet. 5 (citing Ex. 1002 ¶¶ 41–47). Patent Owner does not contest Petitioner’s definition of the skilled artisan. See generally, PO Resp. Neither party argues that the outcome of this case would differ based on our adoption of any particular definition of one of ordinary skill in the art. Moreover, the level of ordinary skill in the art is also reflected by the references themselves. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (“[T]he absence of specific findings on the level of skill in the art does not give rise to reversible error ‘where the prior art itself reflects an appropriate level and a need for testimony is not shown.’”); In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995) (finding that the Board of Patent Appeals and Interferences did not err in concluding that the level of ordinary skill in the art was best determined by the references of record).

- Expert testimonyPatent owner expert discountedDecided for patent owner
“Rather, on the complete record, Patent Owner makes inadequately supported assertions regarding what the skilled artisan “would understand” based on the ʼ084 patent’s disclosure. See PO Resp. 33–34. For example, Patent Owner asserts that “[a] POSITA would understand that” polling or pinging “describes a process where by existing and new devices and/or websites are discovered,” and that “‘polling’ includes asking for information from a website, including a listing of URLs or asking a website of a search engine to provide new website information.” Id. at 34 (citing Ex. 2059 ¶¶ 154–155). We reject this line of argument because we afford minimal weight to Patent Owner’s reliance on paragraphs 153–155 of Exhibit 2059. PO Resp. 33–34. These declaration paragraphs provide little detail beyond what is argued in the Patent Owner Response. See 37 C.F.R. § 42.65 (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”).” slip op. at 22

Thus, we determine that Kurganov-262 is available as prior art against the challenged claims. On the complete record, Patent Owner fails to direct us to specific disclosure within the ʼ996 application that evinces written description for limitation 1.i. Rather, Patent Owner’s citations to the ʼ084 patent fail to describe with adequate precision a computing device configured to periodically search the network(s) to identify new web sites and add such new web sites to the plurality of web sites that are accessed.

“sugar, which indicates that between 2–25% of the particles in EFG sugar can have a size in the range of U.S mesh sieve nos. 20–30. Ex. 2003, 42 (showing the “Typical Analysis” for “X-fine” granulated sugar). Even if we were to agree with Patent Owner that this shows a typical analysis for EFG sugar, it still presents a variance of up to 20% for particles having a size in the range of U.S. mesh sieve nos. 20 and 30. Ex. 2003, 42. Thus, the evidence of record suggests that the particle size distribution for EFG sugar, including the number of particles falling in the range of U.S. mesh sieve nos. 3–35, can vary among different EFG sugars. Thus, the term “typical grocery store sugar,” “might mean several different things” in terms of the number of its particles having a size in the range of U.S. mesh sieve nos. 3–35, and “no informed and confident choice is available among the contending definitions.” HZNP Meds.

“sugar in its products (Ex. 1008, 11:2–5), and Mr. Ebersole’s testimony demonstrates that a person of ordinary skill in the art would have known that Standard Grade and Medium Grade sugars are commercial grade granulated sugars and that the particles in Standard Granulated and Medium Granulated sugars “are almost entirely within the range of U.S. mesh nos. 3–35” (Ex. 2076 ¶ 51). The evidence of record thus supports Petitioner’s assertion that following the typical industry practice of using 1 ounce of tea particles and 1 pound of sugar per gallon of tea, and using a commercial grade granulated sugar (as taught by Cooper) such as Standard Granulated or Medium Granulated sugar (which are known to be “almost entirely within the range of U.S. mesh nos. 3–35”), would yield a product having a blend ratio of tea particles to sugar granules having a size in the range of U.S. mesh sieve nos. 3–35 in the range of 1:16–1:25, as recited in proposed substitute claims 21 and 23. Opp. 20–21; Ex. 1008, 11:2–5; Ex. 1001, 17–20, 57–65. In view of the foregoing, we find Petitioner has established sufficiently that the teachings of Cooper, considered in view of admitted prior art sweetening practices, teaches or suggests all of the limitations of proposed substitute claims 21 and 23. Petitioner has presented evidence demonstrating sufficiently that Cooper teaches the use of sugar having particle sizes falling “almost entirely” within the range of mesh 3–35, that following typical industry practices using such sugar would result in the claimed blend ratio of tea to sugar having a size in the range of mesh 3–35, and that a person of ordinary skill in the art would have had reason to brew commercial-sized batches of tea, with a reasonable expectation of success in doing so, as Cooper allows.” slip op. at 26
