“Kwatra teaches, at Equation 7, minimizing velocity and acceleration of a function representing camera path (P). FF ¶¶ 6, 8–9. Kwatra does not state that this camera path function considers rotation. Rather, the words “camera path” suggest x, y, z movement of the camera rather than rotation of the camera. Dr. Foroosh’s testimony that Kwatra’s minimization of a smoothed camera path does not result in minimizing rotational velocity and acceleration is credible because this testimony is consistent with Kwatra as a whole and consistent with the other evidence of record. Id. ¶ 10. Kwatra recognizes that image rotation angle (“θ”) may not remain smooth. Id. ¶ 12. But rather than attempting to minimize velocity and acceleration of rotation of the camera housing, Kwatra states that applying a smoothness constraint on rotation angle “may be non-linear.” Id. ¶ 13. Consistent with Kwatra, Dr. Foroosh credibly explains the difficulty of applying linear techniques to rotation. Id. Thus, Kwatra proposes instead constraining the sine and cosine of theta. Id. ¶ 14. The Kwatra provisional application is part of the Kwatra reference (id. ¶ 15), and it similarly opts for simpler schemes rather than estimating all parameters for all frames jointly. Id. ¶ 16. The provisional explains that the rotational component is relatively small such that non-linear computations minimizing velocity and rotation can be avoided. Id. ¶¶ 17–18. The testimony of Patent Owner’s witness, Dr. Foroosh, explaining the provisional is credible (Ex. 2018 ¶ 72) because it is consistent with Kwatra’s complete disclosure. Dr. Foroosh’s testimony is more credible than the testimony of Petitioner’s witness, Dr. Katsaggelos, because Dr. Katsaggelos did not review the Kwatra provisional application and, thus, did not review the entire disclosure of Kwatra.

Further, claim 1 states that each location (i.e., each horizontal/vertical position pair) is unique (“one-to-one”) for each unique identifier. Ex. 1001, 8:25–27.

“taught by “the horizontal position of the electronic shelf label along the horizontal shelf part 21, as shown in FIG. 4.” Pet. 21 (citing Ex. 1009 ¶ 75). Certainly, each shelf label in the real world, as well as in the drawing of Figure 4, has a horizontal position. However, that does not mean that Fujiwara’s database stores information indicating the horizontal position of the shelf label as required by the claim. The claim is not calling for the shelf label to have a location; it is calling for location information to be accessible by the server so that the server can determine the location of the mobile terminal. Ex. 1001, 8:19–24 (claiming a “method being performed by a central server configured to access a planogram associating . . . identifiers . . . with . . . locations . . . defined by a vertical and horizontal position”), 8:41–46 (claiming a method step of “determining a location of the mobile terminal . . . based on . . . the planogram). For example, fields in a database storing horizontal and vertical positions would be sufficient. Id. at 6:31–36 (“The central server 2 determines the location of said mobile terminal 1 from the identifier of said electronic label 3 using the data of a planogram associating a location with the label identifier.”), 7:16–18 (calling for the planogram to be stored in a database). To the extent we accept that Fujiwara teaches a unique identifier (shelf label ID) and a vertical position (e.g., shelf number 21-1), we find Fujiwara to be missing a horizontal position as required by the claim because neither the shelf number nor the shelf label ID provides an indication of where along the shelf the shelf label is located.” slip op. at 14

“of oval-shaped void 25 in Cooney is in a “pinched off region” as claimed.

Thus, according to Petitioner, the void’s shape will be similar to the torpedo shape of the via—tapering out on the top half and tapering in on the bottom half. Id. In our view, Petitioner provides a technical reason, supported by testimony, why the bottom of the void will be in the identified pinched-off region of the torpedo-shaped via in Cooney. See id. at 35–38. Patent Owner’s arguments do not address Petitioner’s technical analysis and instead focus on the precision of Cooney’s drawings. See Prelim. Resp. 8–12. Given Petitioner’s technical analysis, however, the precision of Cooney’s drawings is not determinative. Further, Patent Owner’s argument that “void 25 is localized to [the middle portion of the via] and sealed off from the tapered . . . section” also misses the fact that the middle portion of the via still has the torpedo shape (it is the inflection point of where it goes from wider to smaller).

Although we do not reject Petitioner’s declarant’s definition, we also do not adopt it as the meaning of “cascaded transistors” at this time, absent the parties’ proposal that we do.

Reviewing Figure 7 of Okashita, we see a configuration of transistors 1 and 2 that appears, on this record, to be coupled in series.

Petitioner asserts that a person of ordinary skill in the art would have had a reason to take advantage of Okashita’s design: (1) to “reduce the operating temperature of the transistors,” which will “enhance their performance and reliability,” (2) to “prevent leakage of radio frequency signals,” and (3) to “minimize the effect of mismatch.” Id. at 60– 63. Patent Owner’s first argument is that a person of ordinary skill in the art would not look to Okashita because Okashita “is entirely focused on keeping AC and DC grounds separate,” something Patent Owner argues “is not present in Burgener.” Prelim. Resp. 37. It is not clear to us on this record that Patent Owner is correct that keeping AC and DC grounds separate is not present in Burgener, given that Burgener has both AC signals coming in from ports A–D, as well as digital control signals coming in from the control ports (e.g., 1708 and 1718, for port A). See Ex. 1006 ¶¶ 100–101 (discussing RF ports and control signals). In any event, even if the particular problem solved by Okashita is not one of the problems articulated in Burgener, that does not mean that the teachings of Okashita cannot be applied to Burgener. KSR, 550 U.S. at 420 (“any need or problem known in the field . . . and addressed by the patent can provide a reason for combining the elements in the manner claimed”). Petitioner has asserted three reasons, mentioned above, why a person of ordinary skill in the art would look to improve Burgener with Okashita’s teachings, and Patent Owner does not appear to contest them at this time.” slip op. at 26

- Claim Construction › Functional claiming / §112(f) means-plus-function › Whether §112(f) applies (Williamson, nonce words)§112(f) does not applyDecided for petitioner
“We agree that the lack of the word “means” recited in claims 1 and 9 creates a rebuttable presumption that § 112(6) does not apply. Williamson, 792 F.3d at 1348. “When a claim term lacks the word ‘means,’ the presumption can be overcome and § 112[(6)] will apply if the challenger demonstrates that the claim term fails to ‘recite[] sufficiently definite structure’ or else recites ‘function without reciting sufficient structure for performing that function.’” Id. at 1349 (citation omitted). “One way to demonstrate that a claim limitation fails to recite sufficiently definite structure is to show that, although not employing the word ‘means,’ the claim limitation uses a similar ‘nonce word that can operate as a substitute for ‘means’ in the context of § 112 [(f)].’” MTD Products, Inc. v. Iancu, 933 F.3d 1336, 1341 (Fed. Cir. 2019) (quoting Williamson, 792 F.3d at 1350). Patent Owner argues that “[a] general-purpose computer, i.e., a ‘controller,’ fails to recite sufficiently definite structure for performing the DSC’s claimed function.” PO Sur-Reply 3–4. Petitioner responds that the term “controller” has previously been found to not invoke § 112(6) because it is understood as having a definite meaning of structure. Pet. Reply 1–2 (citations omitted). Petitioner is correct that the Board and district courts have in some cases found a “controller” to recite sufficient structure. On this preliminary record, we are not persuaded that the evidence is sufficient to establish that the term “designation software controller” fails to recite sufficiently definite structure and overcome the presumption that § 112(6) does not apply. At this juncture, neither party has provided sufficient evidence as to how the claimed “designation software controller” would reasonably be understood by persons of ordinary skill in the art. See Williamson, 792 F.3d at 1349 (“The standard is whether the words of the claim are understood by persons of ordinary skill in the art to have a sufficiently definite meaning as the name for structure.”). In addition, regardless of whether “designation software controller” alone connotes structure, the claim language that follows the term “designation software controller” appears to provide structure. Specifically, the claim language appears to include a step-by-step procedure, namely 1) keep the information in memory in response to a termination of viewing; and 2) designate the succeeding part of the digital moving image contents when the viewing starts again. See Ergo Licensing, LLC v. CareFusion 303, Inc., 673 F.3d 1361, 1365 (Fed. Cir. 2012) (“Even described ‘in prose,’ an algorithm is still ‘a step-by-step procedure for accomplishing a given result.’”); Sage Prods., Inc. v. Devon Indus., Inc., 126 F.3d 1420, 1427–28 (Fed. Cir. 1997) (“where a claim recites a function, but then goes on to elaborate sufficient structure, material, or acts within the claim itself to perform entirely the recited function, the claim is not in means-plus-function format”). Accordingly, for purposes of this decision, we do not construe the claimed “designation software controller” as a means-plus-function limitation. No further construction of this term is necessary for purposes of this decision. During trial, the parties may provide further briefing on this issue.” slip op. at 10

“Petitioner argues that an ordinarily skilled artisan “would have been motivated to avoid the overfilling of trench sides in Yin’s deep isolation trench that would result from using unchamfered corners by instead using chamfered corners.” Pet. 25 (citing Ex. 1003 ¶ 85).

(citing Ex. 1003 ¶ 85). Petitioner next contends that an ordinarily skilled artisan would have had a reasonable expectation of success because “[c]hamfering the outer corners of Yin’s trench would have required nothing more than an adjustment to the mask pattern that defines the outline of the trench to have chamfered corners instead of square corners.” Pet. 26 (citing Ex. 1003 ¶ 89). Petitioner further contends that “[i]t was also known in the art that 135˚ angle corners (i.e., chamfered), rather than 90˚ angle corners (i.e., unchamfered) were one solution to improve problems associated with trench refill.” Id. at 26–27 (citing Ex. 1003 ¶ 89).
