“When rehearing a decision on petition, the Board will review the decision for an abuse of discretion. See 37 C.F.R. § 42.71(c). An abuse of discretion may be determined if a decision is based on an erroneous interpretation of law, if a factual finding is not supported by substantial evidence, or if the decision represents an unreasonable judgment in weighing relevant factors. See Arnold P’ship v. Dudas, 362 F.3d 1338, 1340 (Fed. Cir. 2004). The party challenging the decision has the burden of showing the decision should be modified, and the request for rehearing “must specifically identify all matters the party believes the Board misapprehended or overlooked, and the place where each matter was previously addressed” in its papers. 37 C.F.R. § 42.71(d).” slip op. at 2

“Owner’s interpretation of “carrier” as meaning “one or more components for supporting ROSA components such as an AWG.” Dec. 9 (quoting Pet. 11). For our analysis of Petitioner’s challenges, we referred to this interpretation of “carrier” as Petitioner’s second alternative construction. Id. We also noted that Petitioner appeared to dispute Patent Owner’s interpretation when it argued that “carrier” should mean “a ceramic or silicon substrate.” Id. (quoting Pet. 10). We referred to this interpretation of “carrier” as the first alternative construction. Id. Rather than resolve this apparent dispute about the meaning of “carrier,” we found that both of Petitioner’s anticipation challenges failed under both interpretations of “carrier.” Id. at 10–26. Because we found that Petitioner had failed to carry its burden regardless of which interpretation of “carrier” applied, we found it unnecessary to resolve the dispute over that interpretation. Id. at 9–10. For the reasons expressed in Parts II.B–C below, we maintain our conclusion that Petitioner has failed to demonstrate a reasonable likelihood of proving that either Shen or Soldano anticipates any claim under either interpretation of “carrier.” Accordingly, Petitioner fails to demonstrate an abuse of discretion in our alleged “refusal” to interpret “carrier.”” slip op. at 3

Nevertheless, we infer that Petitioner intends its statements of “caselaw” to refer to the requirements to make out a case for anticipation. If so, Petitioner demonstrably miscasts what appear to be the legal principles for proving anticipation. As stated in our Decision: “A claim is anticipated only if each and every element as set forth in the claim is found, either expressly or inherently described, in a single prior art reference.” Verdegaal Bros., Inc. v.

The diagnostic test passage therefore only describes a diagnostic test of the build material property but does not describe a subsequent diagnostic test to assess whether an operational parameter is suitable for the printer.

“Although Petitioner has filed a Sotera stipulation, we agree with Patent Owner that the stipulation has limited practical effect in reducing the overlapping efforts here and in the Litigation. Petitioner contends in the district court that the system described in the WebSphere materials renders at least some of the challenged claims invalid. Because Petitioner cannot challenge claims in this proceeding based on a public use or sale of the WebSphere system, Petitioner’s Sotera stipulation would not prevent Petitioner from asserting an invalidity defense in the district court based on the public use or sale of the WebSphere system. We understand that, in the Litigation, Petitioner has relied upon the WebSphere publications as prior art, presumably as evidence describing the WebSphere system that was publicly used and on sale. Regardless of any decision rendered in this proceeding on the patentability of the challenged claims based on the WebSphere printed publications, Petitioner may continue to press an invalidity defense based on the same evidence presented here. Additionally, it appears that all claims being contested as invalid in the Litigation are also subject to a challenge in the Petition. The narrowing of asserted claims in the Litigation, if it occurs, will streamline the parties’ overall dispute on invalidity if we decide to discretionarily deny institution. So, a majority of the parties’ work that would be done here will also be required in the Litigation regardless of whether we institute review. Accordingly, we do not consider the presence of the Sotera stipulation in our case to ensure that inter partes review would be a “true alternative” to the Litigation.

“interview to incorporate prosecution dependent claim 2 into prosecution claim 1 and cancel prosecution dependent claim 3. See § I.F, supra. We determine that this agreement and the corresponding amendment constitutes a clear disavowal of subject matter that supports Patent Owner’s construction. Prosecution claim 2 required that the second communication frame follow the first communication frame after a SIFS (corresponding to Figure 5 of the ’122 patent), while prosecution claim 3 required that there be a SIFS and an intervening response between the first and second communication frames (corresponding to the embodiments of Figures 3 and 4 of the ’122 patent). Before the amendment, original claim 1 included both of these embodiments, but the incorporation of prosecution claim 2 into prosecution claim 1 and the cancellation of prosecution claim 3 limited issued claim 1 to only the embodiment of prosecution claim 2. Because Larsson disclosed an intervening response to the first communication frame before the second communication frame, the clear import of the amendment was to limit claim 1 to the embodiment where the second communication frame follows immediately after the SIFS in order to distinguish claim 1 from Larsson. Indeed, in the Reasons for Allowance, the examiner explained that claim 1 distinguishes over the prior art (including Larsson) because “[t]he prior art of record fails to teach or fairly suggest ‘receiv[ing] the second communication frame after a short inter frame space (SIFS) that follows the first communication frame,’” as added from prosecution claim 2. Ex. 1002, 47. If, as Petitioner argues, prosecution claim 2 was broad enough to cover the embodiment of prosecution claim 3, then the amendment would have served no apparent purpose. Thus, we agree with Patent Owner that “[t]here is no other plausible explanation for why, when faced with Larsson’s disclosure of an intervening response, the Examiner initiated an interview to incorporate the SIFS limitation of dependent claim 2 into claim 1, and cancel dependent claim 3, which, like Larsson, included an intervening response.” See Prelim.

More specifically, those paragraphs recite using prioritization to place the network packets in different queues based on their priority. See Ex. 1005 ¶¶ 191–193. We see nothing in Rao that teaches or suggest that the network packets would be disallowed, as opposed to simply delayed, based on priority. Id.

Although Petitioner explains why a person having ordinary skill in the art would want to consider power usage along with whether the application is in the foreground or background, Petitioner does not explain why a person having ordinary skill in the art would have changed prioritization to blocking. See Pet. 13–18. Indeed, such a modification appears to be one that would render Rao “inoperable for its intended purpose.” In re Gordon, 733 F.2d 900, 902 (Fed. Cir. 1984).” slip op. at 18

“identifies and refers to a valid region of the integrated circuit memory device as having a three-dimensional boundary delimited by phase ranges in command/address signals, data signals, and sampling signals. Nowhere does the ’835 patent specification indicate a valid region of the integrated circuit device as a whole can be represented by values for less than three parameters x, y, and z, all together, e.g., the command signals, the data signals, and the sampling signals. Also, the ’835 patent describes that the purpose of determining the boundaries of a valid region is to configure an optimal operating point for the integrated circuit device. Ex. 1001, 5:48–51. We have also considered other language in the claims. Each of independent claims 1 and 7 requires adjustment of the phase of all three command signals, data signals, and sampling signals, to determine the “valid operation range.” Ex. 1001, 6:56–7:4, 7:18–34. Each of independent claims 12, 20, and 23 requires adjustment of the phase of all three command signals, data signals, and sampling signals, to determine the “valid operating range.” Ex. 1001, 7:46–60, 8:28–44, 8:62–10:4. Based on the foregoing, the specification informs us that “valid operation range” is a three-dimensional range. We recognize that the specification does not expressly exclude a two-dimensional range or multiple two-dimensional ranges from being a “valid operation range” of the integrated circuit device. However, that is why we construe the claims to determine what, if anything, may be required despite a lack of express recitation in the claims.” slip op. at 17
- Skill levelSkill level petitioner adoptedDecided for petitioner
“Level of Ordinary Skill in the Art Citing testimony from Dr. Baker, Petitioner asserts a person of ordinary skill in the art (hereinafter “POSITA”) “would have had a bachelor’s degree in electrical engineering, computer engineering, or the equivalent, and two to three years of experience designing high speed computer memory devices.” Pet. 4 (citing Ex. 1002 ¶¶ 31–35). Patent Owner’s expert, Mr. Lee, testifies: “I agree with Petitioner that [Petitioner’s statement of the level of ordinary skill] would be the minimum qualifications for a POSITA.” Ex. 2001 ¶ 35. On this record, we adopt Petitioner’s statement of the level of ordinary skill in the art, i.e., that a POSITA “would have had a bachelor’s degree in electrical engineering, computer engineering, or the equivalent, and two to three years of experience designing high speed computer memory devices.” Ex. 1002 ¶ 34. The stated level is supported by the testimony of Dr. Baker and not disputed by Patent Owner. Further, it appears consistent with what is reflected by the content of the applied prior art. Cf. Okajima v. Bourdeau, 261 F.3d 1350, 1354–55 (Fed. Cir. 2001) (the applied prior art may reflect an appropriate level of skill). C.” slip op. at 12

“Petitioner still has not made a sufficient showing for limitation [1.4.a]. That is because Petitioner has, at best, identified only two 2-parameter valid operation ranges, i.e., an operation range involving just command and sampling signals, and an operation range involving data and sampling signals. Pet. 29–34. This does not satisfy “valid operation range” as we have construed above in Section III.C. Specifically, we determined that “valid operation range” is a three-dimensional range including a boundary for each of three underlying parameters which, for example, may be the phases of the command signals, the data signals, and the sampling signals. Nowhere has Petitioner identified or explained how Johnson discloses a valid operation range that is a function of three parameters together, e.g., the respective phases of command signals, data signals, and sampling signals. In addition to the foregoing, Petitioner’s reasoning for adjusting the phase of clock signals DCLK, which Petitioner regards as sampling signals, to synchronize with the phase of data signals on the DQ data bus is unpersuasive, because Johnson, as Petitioner has recognized, already adjusts the phase of data signals on the DQ data bus to synchronize with clock signals DCLK. Pet. 32 (citing Ex. 1002 ¶ 136; Ex. 1004, 4:55–59, 6:46–48, 7:25–31, 7:36–42). The proposed adjustment is redundant and serves little, if any purpose. Petitioner has not proposed to stop adjusting the data signals relative to DCLK. Nor has Petitioner articulated a reason to do the adjustment in both directions, i.e., adjusting the data signals relative to the sampling signals and adjusting the sampling signals relative to the data signals. We have also determined above, in discussing limitation [1.3], that Petitioner has not sufficiently shown that Johnson’s CCLK signal is a sampling signal. Further, we agree with Patent Owner (Prelim. Resp. 24) that neither delay 55 nor delay lock loop 41 in Johnson’s Figure 4 is used for systematic calibration of any signal or in a signal calibration process. We find that the mere presence of a delay element in a signal path does not reasonably suggest systematic calibration. For the foregoing reasons, Petitioner has not sufficiently shown that” slip op. at 31
