“Patent Owner does not address the level of skill. See Prelim. Resp. Because Petitioner’s proposed level of ordinary skill in the art is consistent with the field of the invention of the ’275 patent and not disputed by Patent Owner, for purposes of this Decision, we adopt Petitioner’s formulation of the person having ordinary skill in the art.7 7 If Patent Owner disagrees with this formulation of the level of skill in the art, it must raise that disagreement in its Response. If a different level of skill would affect the outcome in this case, the parties must brief that issue as well. The failure of Patent Owner to describe how a different level of skill in the art is determinative will be a forfeiture of that argument. If there is a dispute regarding the level of ordinary skill in the art, then the parties are also encouraged to submit evidence, other than conclusory expert testimony, that supports their position.

On remand, the Board held claim 9 unpatentable as obvious over Agin and Chen, finding Agin teaches the initial power adjustment and the combination teaches the offset determination.
RulingsRemand decision- RemandOther
“Reviewing Patent Owner’s arguments and Petitioner’s assertions, we remain persuaded that one of ordinary skill in the art would have applied the previous power level, i.e., the power level prior to the interruption, and also an offset according to the process illustrated in Agin’s Figure 2. Agin makes clear that its processes in Figure 2 are run “[i]f transmission is not resumed after a transmission interruption” and “[i]f transmission is resumed after a transmission interruption.” Ex. 1004 5:44–50. Figure 2 of Agin is used to make a determination of what the power level would be after an interruption, and that process should be followed, for the first transmission, as well as subsequent transmissions. Agin does not address a separate procedure for the initial transmission after an interruption because the process in Agin’s Figure 2 is generally applicable to all interruptions. This understanding comports with Dr. Ding’s testimony, discussed above, that we credit. See Ex. 2002, 115:13–16, 113:16–22, 110:13–16.” slip op. at 23

Petitioner cites multiple rationales for the combination of Agin and Chen, including the benefits of Chen’s techniques, the predictability of such a combination, improvements in performance and transmission quality, reducing uncertainty, smoothing power levels, and argues that these approaches would have had a reasonable expectation of success. Pet. 17–19.

“We disagree with Patent Owner’s arguments, as we did in the Final Written Decision. See FWD 25–26. We acknowledge the different aims and solutions detailed in Agin and Chen, but we are not persuaded that they are sufficiently different that aspects of Chen could not be utilized in Agin. We also acknowledge that Dr. Jackson’s testimony is clear and he testifies that Chen is sufficiently different and that the processes of Chen would not be readily adaptable to Agin. Weighing the testimonies of Drs. Ding and Jackson, we determine Dr. Ding’s testimony to be more persuasive as to the combination. For example, we concur with Dr. Ding that handover is directly related to communication interruptions in that the handover mechanism exists in order to try to avoid interruptions. Ex. 1003 ¶¶ 67–68, 102, 105–108; Ex. 1111 ¶ 47. Dr. Ding’s testimony is applied to support the conclusion that one of ordinary skill in the art would have been motivated to make the combination.

“Neither party contends that any claim terms require an express construction to resolve the present controversy.

Nonetheless, Petitioner explains that the Petition is structured such that “Ground 1 is based on Patent Owner’s infringement contentions in the district court litigation, where the claimed ‘MUD module’ is generally mapped to multiple-input multiple-output (MIMO) receivers in a wireless network.” Pet. 2. Petitioner contends that “[u]nder this broad interpretation of a ‘MUD module,’ Walton’s MIMO receiver renders every challenged claim obvious.” Id. In contrast to Ground 1, the Petition states that “Ground 2 is based on the plain meaning of ‘MUD module,’ which is a component that detects, separates, and decodes signals from multiple users transmitting simultaneously over the same frequency band.” Id. Petitioner contends that, “[a]pplying the correct meaning of the term, Walton’s MIMO receiver does not necessarily comprise a MUD module.” Id. Therefore, Petitioner explains that “Ground 2 combines Walton with Learned, which expressly discloses [a] multi-user detector, and thus renders every challenged claim obvious in combination with Walton.” Id. at 2–3.7 In other words, the Petition presents Ground 1 and Grounds 2/3 as alternatives depending on the meaning of 7 Although not specifically relevant to claim construction, Petitioner explains that “Ground 3 further combines Walton and Learned with Quigley, to the extent Patent Owner argues Walton does not disclose providing a burst control input.” Pet. 3. “MUD module,” where Ground 1 is based on Petitioner’s understanding of Patent Owner’s interpretation of the term and Grounds 2 and 3 are based on Petitioner’s interpretation of the term as having its plain meaning. Petitioner further contends that “[e]very other claim term carries its ‘ordinary and customary meaning’ . . . .” Id. at 8. Although Petitioner presents a potential dispute regarding the meaning of “MUD module,” we need not construe this term expressly because the determination we reach herein does not depend on which meaning MUD module is applied.

“We find the Petition lacking in particularity because it does not clearly identify what aspect of Jin is alleged to teach the unique signal parameters (or unique estimated signal parameters) recited in claim 1.

First, as reflected above, the Petition asserts that something called a “unique pilot parameter” teaches the recited unique estimated signal parameters. But “unique pilot parameter” is not a term or phrase recited in Jin. See Prelim. Resp. 19 (arguing the same). So, when Petitioner states “Jin discloses that the base station uses the unique pilot parameter (i.e., ‘unique estimated signal parameters’) to ‘identify which user (i.e., mobile terminal) has transmitted the received data,’” it is not clear what element in Jin Petitioner intends to identify by the term “unique pilot parameter.” Dr. Min’s testimony does not help resolve the ambiguity in the Petition. In particular, Dr. Min also refers to a “unique pilot parameter (i.e., ‘unique signal parameter’) for each user.” Ex. 1003 ¶ 89.
