`Patent 6,604,101 B1
`
`
`
`Pursuant to 37 C.F.R. § 42.71(d):
`
`ANALYSIS
`
`A party dissatisfied with a decision may file a single request for
`rehearing without prior authorization from the Board. The
`burden of showing a decision should be modified lies with the
`party challenging the decision. The request must specifically
`identify all matters the party believes the Board misapprehended
`or overlooked, and the place where each matter was previously
`addressed in a motion, an opposition, or a reply.
`
`When reconsidering a decision on institution, we review the decision for an
`
`abuse of discretion. 37 C.F.R. § 42.71(c). An abuse of discretion exists
`
`where a “decision [i]s based on an erroneous conclusion of law or clearly
`
`erroneous factual findings, or . . . a clear error of judgment.” PPG Indus.
`
`Inc. v. Celanese Polymer Specialties Co., 840 F.2d 1565, 1567 (Fed.
`
`Cir. 1988).
`
`Google contends that the Board erred in determining that the broadest
`
`reasonable interpretation of the claim 1 term “contextual search” requires
`
`“identification of relevant documents from the domain-unlimited set of
`
`documents available on the World Wide Web, based on words contained in
`
`the documents.” Req. Reh’g 1–8. Google further asserts that the Board
`
`abused its discretion in relying on this purportedly erroneous construction in
`
`declining to institute trial. Id. at 8–9.
`
`Google acknowledges that the Specification of the ’101 patent “refers
`
`often to Web search and lists a number of search engines that operate over
`
`the Web,” but contends that other portions of the Specification, the claim
`
`language, the file history, and the testimony of Dr. Oard presented to the
`
`3
`
`
`
`IPR2016-00797
`Patent 6,604,101 B1
`
`
`
`Board in conjunction with the Petition necessitate a broader construction that
`
`is not limited to Web search. Req. Reh’g 3.
`
`We have considered, but do not find persuasive, Google’s assertions
`
`that we overlooked or misapprehended the portions of the record identified
`
`in the Request for Rehearing, or that we erred in construing “contextual
`
`search” to mean “identification of relevant documents from the
`
`domain-unlimited set of documents available on the World Wide Web,
`
`based on words contained in the documents.”
`
`Turning first to Google’s contention that our construction of
`
`“contextual search” overlooked the plain language of claim 1 and its
`
`dependent claims (Req. Reh’g 3–4), we observe that the Decision explicitly
`
`discusses the language Google asserts that we have overlooked, and explains
`
`how that language is consistent with, and even supports the Specification’s
`
`exclusive depiction of “contextual search” as a search performed on an
`
`domain-unlimited document set over the Web (see Decision 10).
`
`Furthermore, although Google is correct that the challenged claims “do not
`
`refer to Web search by name” (Req. Reh’g 4), as detailed in the Decision,
`
`the implicit definition set forth in the Specification, the language of the
`
`claims themselves, and the prosecution history support construing
`
`“contextual search” broadly, but reasonably, as “identification of relevant
`
`documents from the domain-unlimited set of documents available on the
`
`World Wide Web, based on the words contained in the documents” (see
`
`Decision, 8–12).
`
`4
`
`
`
`IPR2016-00797
`Patent 6,604,101 B1
`
`
`
`Regarding Google’s contention that we overlooked the prosecution
`
`history for the ’101 patent, we direct Google to the discussion of the
`
`prosecution history set forth in the Decision, and in particular, to our
`
`observation that “the prosecution history explicitly states that ‘[i]ndependent
`
`claims 1, 9, 12, 19, 22 and 23 have herein been amended to further
`
`distinguish a feature of the present invention allowing input of a query in a
`
`first language or source language; and a contextual search of the Internet in
`
`a second or target language.’” Decision 11 (quoting Ex. 2002, 10).
`
`The portions of the prosecution history to which Google now points
`
`do not contradict or otherwise call into question the above-quoted statement
`
`by the Applicants, or our conclusions regarding the effect of the prosecution
`
`history on the interpretation of “contextual search.”
`
`Moreover, Google presents an incomplete and over-simplified
`
`assessment of the prosecution history for the ’101 patent. In particular,
`
`Google’s assertion that “[t]he changes from Web-specific terms to broader
`
`ones shows that Claim 1 and its dependent claims must cover something
`
`broader than only ‘Web search’” (Req. Reh’g 5) ignores the evolution of the
`
`claims during prosecution. For example, contrary to Google’s intimation
`
`(id. at 4–5), amendment of the preamble of claim 1 to recite “in a computer
`
`network” was not a broadening amendment, but a narrowing one. The
`
`preamble of claim 1 evolved during prosecution from reciting “search and
`
`retrieval of multilingual web documents” (Ex. 1010, 19), to encompass the
`
`“search and retrieval of multilingual documents” (id. at 62), before finally
`
`being narrowed to require “contextual search and retrieval of documents in a
`
`5
`
`
`
`IPR2016-00797
`Patent 6,604,101 B1
`
`
`
`computer network” (id. at 92). Google does not account for the context or
`
`chronology of these amendments, or the Applicants’ statement that the
`
`amendments “distinguish a feature of the present invention allowing . . . a
`
`contextual search of the Internet. . .’” (Decision 11 (quoting Ex. 2002, 10.)).
`
`We are similarly unpersuaded by Google’s assertion that we
`
`overlooked Dr. Oard’s testimony that the search engine of claim 1 is not
`
`necessarily a Web search engine (Req. Reh’g 5) in construing the claim term
`
`“contextual search.” Dr. Oard’s comment, in footnote, that the “search
`
`engine in claim 1 is not limited to a Web search engine” because the
`
`’101 patent includes, in the description of the prior art, “an example of a
`
`search engine that was not designed to search Web sites—the Deja News
`
`service” (Ex. 1002 ¶ 109 n.13) is insufficient to support an expansive
`
`construction of the claim term “contextual search.” As an initial matter, we
`
`note that the description of the prior art does not set forth any embodiments
`
`of the claimed invention. In addition, Dr. Oard’s comment is not directed at
`
`the claim term “contextual search” (id.), and tellingly, Dr. Oard does not
`
`discuss Deja News in the portion of his declaration addressed to the
`
`construction of “contextual search,” or otherwise opine that reference to
`
`Deja News as an exemplary special search engine in the description of the
`
`prior art is relevant to the interpretation of the term “contextual search” see
`
`id. ¶¶ 79–81. Rather, Dr. Oard acknowledges that “Deja News was a service
`
`for searching Usenet newsgroups, a type of threaded discussion forum that
`
`was initially shared using store-and-forward techniques and that predates the
`
`6
`
`
`
`IPR2016-00797
`Patent 6,604,101 B1
`
`
`
`World Wide Web” (Ex. 1002, 58 n.13), further calling into question its
`
`relevance to the challenged claims.
`
`Neither do we agree with Google that the claim term “contextual
`
`search,” as it is used in the ’101 patent, may encompass searches of
`
`domain-limited document collections. Google’s reliance on the
`
`exemplification of Deja News as a special search engine in the ’101 patent’s
`
`description of the prior art is again misplaced. The ’101 patent does not
`
`identify Deja News as an embodiment of the claimed invention, characterize
`
`the search performed by Deja News as “contextual search,” or equate the
`
`search methodology of the claimed invention to that of Deja News. See
`
`Ex. 1001, 2:1–4. Rather, as explained above, the ’101 patent confines its
`
`discussion of Deja News to two sentences in the description of the prior art.
`
`In contrast, and as explained in detail in the Decision, the ’101 patent
`
`repeatedly, consistently, and exclusively describes the claimed invention as
`
`an improved system and method for domain-unlimited Web search.
`
`Decision, 8–12.
`
`Google’s parallel assertion that the disclosure of “special search
`
`engines” in the description of the prior art supports a construction of
`
`contextual search that encompasses those search engines (Req. Reh’g 8) is
`
`similarly unavailing. Google does not identify any embodiments of the
`
`invention of the ’101 patent, preferred or otherwise, that perform a
`
`domain-limited search. See Req. Reh’g 5–9. Moreover, contrary to
`
`Google’s suggestion, the Federal Circuit’s decision in PPC Broadband, Inc.
`
`v. Corning Optical Communications RF, LLC, 815 F.3d 734, 741–43 (Fed.
`
`7
`
`
`
`IPR2016-00797
`Patent 6,604,101 B1
`
`
`
`Cir. 2016), does not stand for the proposition that mention of a prior art
`
`system in the description of the prior art constitutes a disclosure of an
`
`embodiment of the claimed invention, or is otherwise relevant to claim
`
`construction. Indeed, the portions of the Specification of the patent-at-issue
`
`on which the Federal Circuit relied in PPC Broadband related to
`
`embodiments of the claimed invention set forth in the summary of invention
`
`and detailed description of the invention. 815 F.3d at 742–743. Critically,
`
`Google does not identify a single embodiment of the claimed invention set
`
`forth in the Specification of the ’101 patent that performs a search on a
`
`domain-limited document set. See Req. Reh’g 5–9.
`
`Lastly, contrary to Google’s speculation, and as made plain by our
`
`Decision, our construction of “contextual search” is not “based on Patent
`
`Owner’s broad assertions about the nature of Web search in its Preliminary
`
`Response” (Req. Reh’g 6), but rather, reflects the implicit definition set forth
`
`in the Specification, the claims themselves, and the prosecution history of
`
`the ’101 patent.
`
`Accordingly, because Google has not shown that we erred in
`
`construing “contextual search” to mean “identification of relevant
`
`documents from the domain-unlimited set of documents available on the
`
`World Wide Web, based on words contained in the documents,” Google has
`
`not established that we abused our discretion in declining to institute trial.

`
`
`
`CONCLUSION
`
`For the reasons given, Google has not demonstrated that we abused
`
`our discretion in denying institution of inter partes review of claims 1, 2, 4,
`
`5, 22, 24, 27, and 28 as obvious in view of Fluhr ’97 and Fluhr ’98; claims 6,
`
`7, and 25 as obvious in view of Fluhr ’97, Fluhr ’98, and Yamabana; or
`
`claim 28 as obvious in view of Fluhr ’97, Fluhr ’98, and Bian. Neither has
`
`Google shown that we misapprehended or overlooked matters raised in the
`
`Petition in our Decision.
`
`Accordingly, it is
`
`ORDER
`
`ORDERED that Google’s Request for Rehearing is denied.
