`
`INTRODUCTION
`Parus’s POR demonstrated that neither Kovatch nor Kurganov-262 is prior
`
`art, the Petition’s combination of Kovatch and Neal does not disclose all the required
`
`claim limitations, and a POSITA would not be motivated to combine Kovatch and
`
`Neal. Petitioners’ Reply does not demonstrate that Kovatch or Kurganov-262 are
`
`prior art. Infra §§ II, IV. Petitioners’ other arguments fail to demonstrate that the
`
`combination of Kovatch and Neal disclose all the required claim limitations, and that
`
`a POSITA would be motivated to combine Kovatch and Neal. Infra § III.
`
`Petitioners’ arguments in regards to the Kovatch and Neal combination in their
`
`Reply only undermine the Petitions’ arguments. Infra § III. Finally, Petitioners’
`
`arguments that the ’431 lacks written description are undermined by the disclosure
`
`of the patent. For these reasons, all Grounds from the Petition fail.
`
`II. GROUNDS 1-4 FAIL BECAUSE KOVATCH IS NOT PRIOR ART
`Petitioners’ fail to establish that the source code identified by Parus was
`
`inoperative for its intended purpose or that any of the elements of the Challenged
`
`Claims were not disclosed by the identified source code. Petitioners’ arguments are
`
`premised on an inaccurate review of the operative facts. As the PTAB observed in
`
`ATI Technologies, operation of a product is sufficient for reduction to practice. ATI
`
`Technologies ULC in LG Electronics, Inc. v. ATI Technologies ULC, IPR2015-
`
`00325 at 18; UMC Elecs. Co. v. United States, 816 F.2d 647, 652 (Fed. Cir. 1987).
`
`1
`
`
`
`Case No. IPR2020-00846
`Patent No. 7,076,431
`Parus adduced evidence in the form of Mr. Kurganov’s declaration, date stamped
`
`source code that showed operation of the product, and email correspondence
`
`showing that the product was operational. Evidence that shows a product would
`
`work for its intended purpose should be sufficient. Parus’s source code worked for
`
`its intended purpose as compiled and tested by Parus. The fact that Petitioners did
`
`not even challenge any of Mr. Kurganov’s assertions regarding the operation of the
`
`source code during his deposition shows the maturity of the source code.
`
`Parus’s Antedating of Kovatch Should Not Be Rejected
`A.
`Petitioners’ assertion that Parus’s antedating is conclusory is unfounded.
`
`(Paper 22, 2-5). Parus’s POR demonstrates that the ’431 and ’084 inventions were
`
`conceived and reduced to practice before Kovatch’s priority date. The POR,
`
`associated declarations, cited exhibits, and the declaration of Parus’s expert,
`
`Benedict Occhiogrosso, demonstrate that Parus conceived and reduced to practice
`
`the ’431 and ’084 inventions before Kovatch’s priority date.
`
`Contrary to Petitioner’s unfounded assertions, the POR does not improperly
`
`ask Petitioners and the Board to sift through 1,300+ pages of exhibits to assess
`
`whether the evidence could support Parus’s antedating as Petitioners contend.
`
`(Paper 22, 3).
`
`In its’ antedating materials, Parus included claim charts that used excerpts of
`
`the source code to demonstrate exactly which parts of the source code met the claim
`
`2
`
`
`
`Case No. IPR2020-00846
`Patent No. 7,076,431
`limitations in claim charts and included the entire source code files for Petitioners’
`
`inspection. Petitioner and its expert does not challenge whether the source code
`
`actually performs the Challenged Claims. Further, Parus included extensive source
`
`code versioning records to demonstrate that the versions of the source code that
`
`Parus cites, were in fact entered into the source code versioning system by
`
`12/31/1999. Finally, Parus provided email communication that showed that the
`
`system was complete.
`
`1. Mr. Kurganov’s testimony is supported by independent
`corroboration
`Petitioners allege that Mr. Kurganov’s testimony is uncorroborated. (Paper
`
`22, 6). This is not true. Parus provided a number of exhibits that corroborated Mr.
`
`Kurganov’s testimony, including contemporaneous email communications and
`
`source code. (Ex. 2020-2060). Mr. Mulka pulled the source code commits out of
`
`the source code versioning system while creating a detailed report of activity in the
`
`source code revision system. (Ex. 2058). Each of the entries in this report
`
`demonstrated that the files were indeed committed to the system by the relevant date.
`
`Petitioners found no substantive issues with this report. (Paper 22). Further, Mr.
`
`Mulka authenticated all of these files during his deposition. (Ex. 1052, 54:5-56:15).
`
`Mr. Kurganov recognized the files and detailed how they demonstrated that the code
`
`functioned for its intended purpose. (Ex. 2020, 2027, 2028). Petitioners had every
`
`3
`
`
`
`Case No. IPR2020-00846
`Patent No. 7,076,431
`opportunity to dispute Mr. Kurganov’s testimony, but chose not to. At his
`
`deposition, Petitioners did not challenge Mr. Kurganov’s testimony related to the
`
`functionality of the produced source code. (Ex. 1050). Parus asked Petitioners’
`
`expert, Dr. Martin Walker, if the code did not work for its intended purpose, and Dr.
`
`Walker indicated that he did not form an opinion as to whether the code functioned
`
`for its intended purpose.1 (Ex. 2061, 41:24-42:15; Ex. 1053). The source code
`
`worked for its intended purpose and practiced all of the elements of the Challenged
`
`Claims.
`
`Mr. Occhiogrosso examined Mr. Kurganov’s declaration and his exhibits and
`
`testified as a POSITA that the source code worked as Mr. Kurganov testified. (Ex.
`
`2059, ¶¶ 44-91). Petitioners have not challenged that analysis in any real way.
`
`Further, as previously discussed, Mr. Mulka created a detailed report of activity in
`
`the source code revision system demonstrating that Mr. Kurganov and Mr. Zhukov
`
`worked full time and consistently on the WA-II enhancements, which embody the
`
`Challenged Claims for at least a month and a half before the effective date of
`
`Kovatch.
`
`1 Dr. Walker testified that because the getWeather() was commented out, the code did not function for its intended
`purpose but could provide no opinion whether or not the defined function included defects.

`
`
`
`Case No. IPR2020-00846
`Patent No. 7,076,431
`Parus’s evidence meets both reduction to practice prongs
`2.
`Contrary to Petitioners’ assertions, Parus’s evidence meets both reduction to
`
`practice prongs. For example, Parus’s POR and exhibits demonstrate its antedating
`
`case in a similar, but distinguishable manner over ATI Technologies. (ATI
`
`Technologies, IPR2015-00325). In ATI Technologies, the Board held that in order
`
`to establish reduction to practice, the inventor must establish (1) the inventor
`
`constructed an embodiment or performed a process that met all of the claim
`
`limitations; and (2) the invention would work for its intended purpose. (IPR2015-
`
`00325, Paper 62, 17 (citing to Cooper v. Goldfarb, 154 F.3d 1321, 1327 (Fed. Cir.
`
`1998))).
`
`a.
`
`Parus’s evidence demonstrates an embodiment meeting
`all limitations of the challenged claims
`Parus’s evidence demonstrates an embodiment meeting all limitations of the
`
`challenged claims contrary to Petitioners’ assertions. (Paper 22, 9-12). For example,
`
`in ATI Technologies, for the first prong, ATI argued that the register-transfer level
`
`(“RTL”) code was a constructed embodiment of the claimed invention, which was a
`
`graphics processing system. (IPR2015-00325, Paper 21, 16). ATI provided an
`
`inventor declaration analyzing source code material in the form of RTL to show the
`
`operation of ATI’s product. (IPR2015-00325, Ex. 2006). ATI argued that RTL code
`
`itself constituted an actual reduction to practice. (IPR2015-00325, Paper 16, 16-21).
`
`5
`
`
`
`Case No. IPR2020-00846
`Patent No. 7,076,431
`The Board found that the RTL code was not a sufficient constructed
`
`embodiment because ATI had not demonstrated that “the design inferred by the RTL
`
`code was synthesized into a set of interconnected hardware devices.” (IPR2015-
`
`00325, Paper 62, 19). The Board noted that “ATI does not contend that the computer
`
`system executing the RTL code encompasses the claimed graphics processing
`
`system, but rather RTL code, alone, is an embodiment of the claimed system.”
`
`(IPR2015-00325, Paper 62, 25).
`
`Parus’s antedating case is distinguishable over ATI for two reasons. First, the
`
`source code alone is an actual reduction to practice of the claimed invention because
`
`unlike the RTL code in ATI Technologies, that only demonstrated the design of the
`
`system and was not synthesized into a set of interconnected hardware devices, the
`
`source code does not need to be synthesized into a physical embodiment and
`
`demonstrates the functionality of the Challenged Claims.
`
`Second, in the alternative and in contrast to ATI, where ATI provided RTL
`
`that describes the design of the circuits in the graphics processing system and needs
`
`to be synthesized into a physical embodiment, and argued that the RTL is a physical
`
`embodiment, Parus provides source code that defines the functionality of the system,
`
`and need not be synthesized into a physical embodiment, in addition to the claimed
`
`computer making up an actual reduction of practice of the system of the claims of
`
`the ’431 and ’084 patents.
`
`6
`
`
`
`Case No. IPR2020-00846
`Patent No. 7,076,431
`
`b.
`
`The evidence demonstrates an embodiment having a
`computer meeting all claimed limitations
`The evidence demonstrates an embodiment having a computer meeting all
`
`claimed limitations, contrary to Petitioners’ assertions. (Paper 22, 9-10). For
`
`example, Mr. Kurganov’s testimony and the evidence presented demonstrate that the
`
`claimed computer was embodied by a UNIX cluster of servers that was used to
`
`provide Parus’s Webley Assistant product. (Ex. 2020, ¶ 14; Ex. 2025). Petitioners’
`
`attempts to confuse the claimed computer with the computers that housed the source
`
`code versioning system have no merit. (Paper 22, 9). The source code that was
`
`identified by Mr. Kurganov was tested and provides evidence of a working reduction
`
`to practice on that UNIX cluster of servers.
`
`The working reduction to practice is a functional embodiment of the
`
`invention. As testified to by Mr. Kurganov and corroborated by contemporaneous
`
`evidence, the claimed computer, the Unix cluster of servers, executed the binary
`
`program which was the compiled and linked source code. Mr. Kurganov makes this
`
`clear in his declaration as well in his deposition testimony and email
`
`communications that the system was operational. (Ex. 2020, ¶¶ 20-102; Ex. 2021-
`
`2057; Ex. 1050, 21:17-22:8, 32:17-23). There is no limitation requiring the claimed
`
`computer to house the source code versioning system, and Petitioners provide no
`
`evidence to support their suggestion.
`
`7
`
`
`
`Case No. IPR2020-00846
`Patent No. 7,076,431
`Further, Petitioners attempt to insinuate that the claimed computer was
`
`required to compile and link the source code. (Paper 22, 9). Again, there is no
`
`limitation requiring the claimed computer to compile and link the source code into
`
`an executable binary program, and Petitioners provide no evidence to support their
`
`suggestion. The source code identified by Mr. Kurganov shows conclusively that
`
`the embodiment of the invention memorialized by the source code operated for its
`
`intended purpose. Petitioners do not even challenge that showing.
`
`The evidence shows that the alleged source was developed, compiled, and run
`
`on the claimed computer before Kovatch’s priority date. Petitioners argue that there
`
`is no evidence that corroborates that all the files Parus presented “could be or ever
`
`were used together on the same computer.” (Paper 22, 10). Mr. Kurganov provided
`
`evidence that walked through each source code file highlighting where the claimed
`
`functionality of the ’431 and ’084 patents could be found in the code. Petitioners
`
`identify absolutely no error in the source code or alleged failure in the operation of
`
`the source code. Petitioners did not challenge Mr. Kurganov’s or Mr.
`
`Occhiogrosso’s interpretation of the source code as performing any of the claim
`
`elements of the Challenged Claims. Further, Mr. Mulka compiled extensive source
`
`code versioning system records corroborating that Mr. Kurganov, and Mr. Zhukov,
`
`the other named inventor, worked on the WA-II enhancements until they were
`
`finished. When asked at his deposition, whether there was any reason to not believe
`
`8
`
`
`
`Case No. IPR2020-00846
`Patent No. 7,076,431
`Mr. Kurganov’s testimony, or whether he determined that the all the cited source
`
`code files could not be compiled together, Petitioners’ expert Dr. Walker refused to
`
`provide an opinion. (Ex. 2061, 41:24-42:15, 18:2-21).
`
`c.
`
`The evidence demonstrates a constructed embodiment
`met limitations [1pre], [1.h]-[1.k]
`Petitioners’ main argument regarding these claim limitations is that the call to
`
`the getWeather() function was commented out therefore it was never compiled.
`
`(Paper 22, 10-11). Neither Petitioners, nor Dr. Walker, provide any evidence that
`
`the getWeather() functionality was not working for its intended purpose at the time
`
`the source code file was committed to the source code versioning system. (Ex. 2061,
`
`41:24-42:15). Instead, Petitioners argue that because the call was commented out in
`
`this particular source code commit, then it must have never worked. The
`
`getWeather() function is less than a page in length. If there was an error in the code,
`
`Dr. Walker could have quickly analyzed and identified it. In his deposition, Dr.
`
`Walker admitted he did not have an opinion whether the code worked for its intended
`
`purpose or not. The idea that the code never worked because the call was
`
`commented out in this particular source code commit is unsupported.
`
`Petitioners provide no evidence demonstrating the getWeather() functionality
`
`did not work for its intended purpose. They cannot because the evidence
`
`demonstrates that the getWeather() functionality did indeed work. Mr. Kurganov’s
`
`9
`
`
`
`Case No. IPR2020-00846
`Patent No. 7,076,431
`testimony and the evidence provided in his declaration demonstrated what the lines
`
`of code did in the getWeather() function. (Ex. 2020, ¶¶ 22-28; Ex. 2027-2028, 5-8).
`
`Petitioners failed to find any fault with Mr. Kurganov’s explanation of the source
`
`code itself, which had only 1 line commented out.
`
`Instead, Petitioners rely on the commented out call to getWeather() and then
`
`conclude it never worked. Dr. Walker testified that it is common to comment out
`
`code when it is not working. But Dr. Walker failed to acknowledge that it is also
`
`common to comment out code when it is working in order to work on another part
`
`of the system that may not be working. Further, Petitioners fail to acknowledge that
`
`the source code in the version control system is just the main line of source code.
`
`Any developer could have had the source code checked out on their own machine,
`
`uncomment the code, and compile and execute the getWeather() functionality.
`
`d.
`
`The evidence demonstrates an embodiment meeting
`claim 9’s additional limitations
`Petitioners’ claim that evidence does not demonstrate an embodiment meeting
`
`claim 9’s limitations is not true. (Paper 22, 11-12). Claim 9 adds the limitation that
`
`“said computer is further configured to periodically search said internet to identify
`
`new web sites and to add said new web sites to said plurality of web sites.” Mr.
`
`Kurganov explained that the url.pl file “would be used on the computer to grab any
`
`URL and return its content for further processing and determination if that url
`
`10
`
`
`
`Case No. IPR2020-00846
`Patent No. 7,076,431
`contains useful information and should be added as a source.” (Ex. 2020, ¶ 44). He
`
`also testified that the file was used in conjunction with a search engine to periodically
`
`search said internet to identify new web sites. Id. Petitioners do not point to any
`
`evidence undermining Mr. Kurganov’s testimony because looking at the url.pl file
`
`and Mr. Kurganov’s testimony, it is clear that the url.pl was used in the manner that
`
`Mr. Kurganov testified to meet this claim limitation.
`
`e.
`
`The evidence demonstrates an embodiment meeting
`claim 14’s additional limitations
`The evidence demonstrates an embodiment meeting claim 14’s additional
`
`limitations. For example, the email shows a script that creates a database table when
`
`run. (Ex. 2057). Mr. Kurganov’s testimony confirms that understanding. (Ex. 2020,
`
`¶ 82). Petitioners attempt to demonstrate that Mr. Occhiogrosso did not corroborate
`
`Mr. Kurganov’s testimony. (Paper 22, 12). This is a mischaracterization of Mr.
`
`Occhiogrosso’s testimony. Mr. Occhiogrosso clearly pointed out an error in his
`
`declaration, and indicated that the evidence he relied on was the evidence that he
`
`cited (Ex. 2027, 49-51) in his declaration. (Ex. 1051, 112:6-14). The evidence that
`
`Mr. Occhiogrosso relied on is the same email that shows a script that creates a
`
`database table when run. Thus, Mr. Occhiogrosso testimony is sufficient and did
`
`corroborate Mr. Kurganov’s testimony, contrary to Petitioners’ allegations. (Paper
`
`22, 12).

`The evidence demonstrates a working embodiment.
`3.
`Contrary to Petitioners’ assertions, the evidence demonstrates a working
`
`embodiment. (Paper 22, 13-16). For the second prong, Parus demonstrated the
`
`system worked for its intended purpose. (Ex. 2020; Ex. 2027-2028; Ex. 2021-2057).
`
`For example, Parus provided an inventor declaration, exhibits, and associated source
`
`code that delineated how the claimed system functioned for its intended purpose and
`
`practiced the various elements of the Challenged Claims. Id. Mr. Kurganov’s
`
`testimony regarding the source code, emails between Mr. Kurganov and Mr.
`
`Zhukov, and a press release, all included in Mr. Kurganov’s declaration, demonstrate
`
`a working embodiment.
`
`For example, in Mr. Kurganov’s declaration, he refers to the voice response
`
`system that practices the elements of the Challenged Claims as “web agents.” (Ex.
`
`2020, ¶¶ 12, 112-119). On August 24, 1999, an email between the two inventors
`
`demonstrate that they were working on these web agents. (Ex. 2020, ¶ 112; Ex.
`
`2044). By December 17, 1999, another email between the two inventors
`
`demonstrate that the web agents were completed. (Ex. 2020, ¶ 114; Ex. 2050).
`
`Specifically in that email, Mr. Zhukoff stated that, amongst his accomplishments for
`
`the year, he had “[d]esigned/developed/implemented stock quote, weather, flight
`
`delays agents.” (Ex. 2020, ¶ 114, Ex. 2050 at 1). Those functions, which track the
`
`source code identified by Mr. Kurganov, were operational. Further, Mr. Kurganov
`
`12
`
`
`
`Case No. IPR2020-00846
`Patent No. 7,076,431
`pointed to a press release advertising the system enhancements to customers, which
`
`was published in February 2020. (Ex. 2020, ¶ 118; Ex. 2056). The timing of that
`
`press release is consistent with having a working system in December 1999. Again,
`
`Petitioners and Petitioners’ expert have not provided any challenge as to whether the
`
`identified source code would operate in the manner described by Mr. Kurganov.
`
`(Paper 22; Ex. 2061, 41:24-42:15; Ex. 1053).
`
`The reduction to practice dates are corroborated
`4.
`As already discussed, Mr. Mulka pulled the source code commits out of the
`
`source code versioning system while creating a detailed report of activity in the
`
`source code revision system. (Ex. 2060; Ex. 2058). Each of the entries in this report
`
`corroborated that the files were indeed committed to the system by the relevant date.
`
`Petitioners found no issues with this report. (Paper 22). Finally, Mr. Mulka
`
`authenticated all of these files during his deposition. (Ex. 1052, 54:5-56:15).
`
`III. PETITIONERS’ REBUTTAL ARGUMENTS FAIL
`Petitioners’ counter arguments to the arguments that Parus advanced in the
`
`POR, only highlight weaknesses in the Petition.
`
`A.
`
`Petitioners Fail to Address Several Issues Regarding the
`purported Kovatch and Neal Combination Raised by Parus in Its
`POR
`Instead of attempting to rebut issues regarding the purported Kovatch and
`
`Neal combination that Parus raised in its POR, Petitioners ignore, mischaracterize,
`
`13
`
`
`
`Case No. IPR2020-00846
`Patent No. 7,076,431
`and claim that these arguments do not matter. Petitioners are wrong. The issues
`
`raised by Parus go to the very heart of purported Kovatch and Neal combination, and
`
`ignoring them proves fatal to Petitioners case.
`
`1.
`
`The fact that neither Kovatch nor Neal disclose claim
`limitation 1(j) is indeed material
`It is an undisputed fact that neither Kovatch nor Neal disclose the sequentially
`
`accessing a plurality of pre-selected web sites until the information to be retrieved is
`
`found or all web site have been accessed claim limitation. (Paper 2, 12-15, 32).
`
`Petitioners claim that the fact Kovatch does not disclose this limitation is immaterial.
`
`(Paper 22, 16). Kovatch’s lack of disclosure of claim limitation 1(j) is indeed
`
`material because adding it to Kovatch goes against the stated goal of Kovatch.
`
`(Paper 14, 22).
`
`For example, Kovatch explains that “[t]he intent of the system is to be able to
`
`come up with a single choice destination amongst the many offered within the
`
`system.” (Ex. 1005, 4:29-30 (emphasis added); Paper 14, 22). In its POR, Parus
`
`noted that in Kovatch the “Anita Language Engine in conjunction with [the] Anita
`
`Query Engine identify destination nodes and the applications available to the user.”
`
`(Paper 14, 22). Parus further pointed out that “the Anita Query Engine maps
`
`commands to applications which are destination nodes in the tree.” Id. Parus also
`
`14
`
`
`
`Case No. IPR2020-00846
`Patent No. 7,076,431
`noted that all of the applications, such as the weather application, are mapped to
`
`single destination URLs. (Paper 14, 20-23).
`
`Petitioners argue that it would be obvious to add the functionality of claim
`
`limitation 1(j) to Kovatch, which would add a plurality of pre-selected destinations
`
`to Kovatch, while completely ignoring and not explaining why a POSITA would
`
`modify Kovatch in a manner that is completely opposite of Kovatch’s stated goal.
`
`(Paper 2, 12-15, 32). Kovatch’s lack of disclosure of claim limitation 1(j) is indeed
`
`material, and Petitioners failure to explain why a POSITA would modify Kovatch
`
`in the manner they suggest is fatal to their case.
`
`2.
`
`Neal does not disclose or teach accessing websites is
`material
`Parus argued the importance of Neal not disclosing or teaching accessing
`
`websites because neither Kovatch nor Neal disclosed claim 1(j), and Petitioners’
`
`purported combination of Kovatch and Neal leaves many questions unanswered, and
`
`Parus wanted to foreclose any wavering by Petitioners in an attempt to answer these
`
`unanswered questions.
`
`3.
`
`Kovatch does not disclose “website search methodology”
`that Petitioners rely on in their purported Kovatch/Neal
`combination
`Parus did not mischaracterize Neal and the Petition when it argued that Neal
`
`teaches away from keyword matching as a search strategy. The Petition clearly
`
`states that “[a] POSA would have been motivated to apply Neal’s above-described
`
`15
`
`
`
`Case No. IPR2020-00846
`Patent No. 7,076,431
`hierarchical ordering and search techniques when retrieving information from web
`
`sites in Kovatch’s HeyAnita system.” (Paper 2, 13-14). Neal explains that its search
`
`strategies, which Petitioners alleged they were relying on, “may include one or more
`
`of the following: exact search, stem search, soundex search, and fuzzy logic search.”
`
`(Ex. 1007, 3:30-32). Neal is the only reference advanced by Petitioners that teaches
`
`any searching techniques, and the only way to search a web page would be a
`
`keyword matching strategy. If Petitioners are relying on Kovatch for the searching
`
`of data on a web page, which Petitioners now claim, then all grounds fail because
`
`Kovatch does not teach any search methodology. (Paper 22, 17).
`
`For example, Petitioners now argue that Kovatch is relied upon “for a teaching
`
`of searching web sites” and refer to “Kovatch’s website search methodology,” but
`
`there is no disclosure of website searching in Kovatch. (See Ex. 1005; Paper 22,
`
`17). Petitioners are now relying on Kovatch’s web parser to “search each individual
`
`website.” Id. But a web parser, parses the HTML tags on a web page to expose or
`
`render the data to the user; it does not search any data, and Kovatch’s web parser is
`
`no different.
`
`In the purported Kovatch/Neal combination, Petitioners fail to explain how
`
`the system would search for the desired information once the web parser converts
`
`the unstructured HTML data into meaningful structured data. The only reasonable
`
`interpretation of the Petition is that Petitioners are relying on Neal to search this
`
`16
`
`
`
`Case No. IPR2020-00846
`Patent No. 7,076,431
`structured data to get the requested information, and Parus’s arguments focused on
`
`the fact that once the HTML data is converted to text by
