    • Skill levelSkill level petitioner adoptedPetitioner expert creditedDecided for petitioner

      “C. Level of Ordinary Skill in the Art Petitioner’s declarant, Dr. Ratner, testifies that a person of ordinary skill in the art at the time of the alleged invention “would have had an undergraduate degree in Computer Science or a related field, such as Electrical Engineering, and two to three years of experience working in the field, or an equivalent level of experience.” Ex. 1005 ¶ 17; Pet. 14. Patent Owner does not challenge this definition or present its own. Accordingly, we credit the testimony of Dr. Ratner regarding the level of ordinary skill in the art, and find that a person of ordinary skill in the art would have had an undergraduate degree in Computer Science or a related field, such as Electrical Engineering, and two to three years of experience working in the field, or an equivalent level of experience. This level of ordinary skill is reflected not only by the information presented by the parties, but also by the prior art of record. Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (the prior art itself can reflect the appropriate level of ordinary skill in the art).” slip op. at 9

    • Novelty / Anticipation (§102) › Prior-art status of a reference › Printed publication / public accessibilityPrinted publication establishedDecided for petitioner

      “We agree with and adopt Petitioner’s reasoning and determine Rabinovich to be a printed publication. We credit the unrebutted testimony of Dr. Rabinovich regarding the consistency of his professional practice in 1998 for republication of his AT&T technical memoranda on a webpage that he managed on AT&T’s publicly accessible website. Furthermore, we find the December 1998 IEEE article corroborates the public availability of Rabinovich on that website, and would have been a roadmap, for one of ordinary skill in the art of data management and optimized access to data, to be guided to Rabinovich. See Reply 21–22. As Petitioner points out, Patent Owner’s own declarant states that Rabinovich and the December 1988 IEEE article “are ‘similar[]’ in that they both address ‘problems in network connectivity caused by multiple clients accessing servers.’ (Ex. 2006 at 12).” Id. at 20. Additionally, the passage in the December 1998 IEEE article that cites to Rabinovich refers to an algorithm in Rabinovich for optimizing access to data in order to increase performance. Id. at 21. Accordingly, we find that footnote 16 of the IEEE article, which contains the URL to Rabinovich, would have guided one of ordinary skill directly to Rabinovich. We are, therefore, persuaded, that Rabinovich is a printed publication under 35 U.S.C. § 102.” slip op. at 12

      “whether to replicate data object xs. Rabinovich defines cnt(s,xs) as the “total access count for xs,” which is equal to cnt(xs). Ex. 1006, 11. According to Dr. Ratner, “[t]he metric cnt(s,xs) measures the total number of times in that window that replica xs has been served to a client computer.” Ex. 1005 ¶ 253. As Patent Owner points out, Rabinovich teaches replicating/migrating object xs only if the ratio of cnt(s,xs) over aff(xs) is greater than m, and the ratio can be greater than m only if cnt(s,xs) is greater than zero. PO Resp. 19; Ex. 1006, 12, Fig. 4. In view of this, we agree with Patent Owner that if cnt(s,xs) has a value of zero, meaning that object x has not been served to any client computer, then the ratio of cnt(s,xs) to aff(xs) will be zero, i.e., less than m, and Rabinovich will not carry out its replication or migration step. This means that Rabinovich will not replicate or migrate object xs until xs has been accessed by a client computer at least once, such that the access count for xs is greater than zero. In this regard, we agree with Patent Owner that object xs is not “sen[t], from the at least one data storage device to the another data storage device . . . independent of an access of the at least one client computer” because Rabinovich teaches explicitly that object xs is not sent unless there has been at least one access from the client computer.” slip op. at 18

    • Obviousness (§103) › Graham factors (scope of art, differences, level of skill)Not shown unpatentableNot shown unpatentable

      “30, for use with a computer game (claim 45) and with an interactive computer game accessed by at least two users (claim 46). Ex. 1001, 30:47– 54. In connection with its obviousness contentions, Petitioner makes no separate arguments why Rabinovich teaches or suggests shifting redundantly stored data based upon data transmission parameters between the servers independent of an access of the client. Pet. 45–47; Reply 17–18. Because claims 45 and 46 depend from claim 30, we find that Petitioner has failed to demonstrate by a preponderance of the evidence that Rabinovich teaches or suggests the limitations in these two dependent claims for the same reasons discussed above with respect to claim 30.” slip op. at 21

    The Board held claims 1–4, 14–20, 27, and 29 not unpatentable because Averbuj did not disclose a control module configured to generate the claimed address signals.

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “Based on a comparison of Dr. Bagherzadeh’s and Dr. Sechen’s declarations (Exs. 1009, 2019), we find Dr. Bagherzadeh has a broader range of educational and work experience, and, therefore, accord greater weight to his opinion as to the level of ordinary skill in the art. Dr. Bagherzadeh’s opinion is consistent with our finding as to the level of ordinary skill in the art in our Final Written Decision in IPR-970. We, therefore, adopt our finding in IPR-970 as to the level of ordinary skill in the art: [A] person of ordinary skill in the art at the time of the ’434 patent would have a Bachelor’s degree in electrical engineering, computer engineering, or in a related field and at least one year of work experience relating to memory systems, and would be familiar with the design of memory devices, memory modules, and BIST. IPR-970 FWD, 10–11 (noting that our finding was “based on our review of the ’434 patent and the types of problems and solutions described in the ’434 patent and cited prior art”).” slip op. at 10

    • Expert testimonyPetitioner expert discountedDecided for patent owner

      “We are not persuaded by Dr. Bagherzadeh’s testimony because it is devoid of specific facts and analysis as to what led him to conclude that a person of ordinary skill in the art would interpret the claim term “generate” in the manner Petitioner proposes. See id. Dr. Bagherzadeh does not explain how the IEEE definition supports an interpretation of generate as “cause or initiate transmission,” terms that do not appear in the IEEE definition. See id. Nor does Dr. Bagherzadeh identify other extrinsic evidence which he believes to be consistent with an interpretation of “generate” as meaning “cause or initiate transmission.” See id. Likewise, Dr. Bagherzadeh has not explained why he believes the ’434 patent “describe[s] generating as initiating or transmitting” (Ex. 1009 ¶ 28), as these terms do not appear in the cited portions of the ’434 patent. See Ex. 1008, 6:3–5, 10:67–11:2, 6:14–17. Accordingly, Dr. Bagherzadeh’s testimony does not persuade us to accept Petitioner’s interpretation of “generate” as meaning “cause.”” slip op. at 15

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner

      “supports a finding that a customary meaning of “generate” to one of ordinary skill in the art is “cause.”1 We, therefore, determine the broadest reasonable 1 Petitioner relies on Webster’s II, for a definition of “cause.” See Reply 4, 6–8 (citing Ex. 1032, 3). Having determined the broadest reasonable interpretation of “generate” does not encompass “cause,” we do not find this evidence relevant to our claim construction analysis. construction of “generate” is “produce” for the reasons stated above and in our Final Written Decision in IPR-970. We adopt and incorporate by reference our analysis and construction of the term “generate” in our Final Written Decision in IPR-970 (IPR-970 FWD, 24–33).” slip op. at 16

      “Moreover, the evidence in this proceeding fails to support a finding that Averbuj’s BIST controller 4 is configured to generate address signals for testing the memory devices in the manner claimed. In Averbuj, the algorithms (i.e., CMD_DATA containing OP CODE such as SET ADDRESS (see Ex. 1011, 4:4–12, 5:19–21, Table 1)) communicated to sequencers 8 are either received by user interface 22 via external input (id. at 5:41–43) or generated by another component (i.e., a component that is not part of BIST controller 4 circuitry) and stored in algorithm memory 20 (see Ex. 2012, 30:23–24, 41:1–4, 54:21–22, 55:6–25, 55:20–56:9 (wherein Dr. Bagherzadeh testifies that OP CODE residing in the algorithm memory of BIST controller 4 are generated by hand or by a tool, e.g., a compiler, and that “99 percent of the designs or chips do not have a compiler on-board”)). Multiplexer 24 selects one of the algorithms (i.e., CMD_DATA) and BIST controller 4 provides to sequencers 8 the same CMD_DATA (e.g., address signals) without transformation or modification. See Ex. 1011, 4:4–12, 5:16–21; Ex. 2012, 54:8–13 (“Averbuj Figure 2, without consideration of any other disclosure in Averbuj, illustrates that a multiplexer selects an input from the algorithm memory and the output [] reflect[s] what’s in the input, based on the selection.”). Based on our interpretation of the terms “configured to” and “generate,” as discussed above, the claim recitation “a control module configured to generate address . . . signals for testing the memory devices” (claims 1, 20, and 29) does not read on Averbuj’s BIST controller 4, because the SET ADDRESS signal output by BIST controller 4 is produced by a component external to BIST controller 4, and merely selected by multiplexer 24 and provided to sequencers 8 without transformation or modification by BIST controller 4. In sum, after considering the parties’ arguments and evidence, we determine Petitioner has not shown, by a preponderance of the evidence, that Averbuj discloses “a control module configured to generate address . . . signals for testing the memory devices” as recited in independent claims 1, 20, and 29. Petitioner does not correct this deficiency in its challenges as to dependent claims 2–4, 14–19, and 27. See Pet. 32–39; 35 U.S.C. § 112, ¶ 4 (“A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers.”). Because Petitioner has not identified in Averbuj a teaching of each and every limitation recited in claims 1–4, 14–20, 27, and 29, Petitioner has not met its burden to show these claims are unpatentable under 35 U.S.C. § 102(b) as anticipated by Averbuj.” slip op. at 30
