The applicant explained that films can be compatible with PET recycling in two ways, (1) the film can float in water and be separated from PET that sinks in water or (2) the PET films crystallize and “can be recovered with the PET stream.” Id. at 336 (citing “A Resource Document by the Association of Plastic Recyclers (APR)”) (found at Ex. 1002, 323–332) (emphasis omitted). The applicant explained that “removing the label before or during the recycling process is not evidence of the recyclability of the label” and that “[r]emoving the label during the recycling process is not equivalent to actually recycling the label.” Id. at 335.

“To determine how a person skill in the art would determine if a shrink label is “recyclable” as recited in the independent claims, we look to how the Specification of the ’422 Patent describes or defines recyclable shrink labels. For example, the ’422 Patent states that PET shrink films are generally considered recyclable if no inks are retained on the film after a caustic wash cycle typically used in PET reclaiming processes. Ex. 1001, 6:61–65. The ’422 Patent further states that labels are fully recyclable if the polymers used are clear, preferably clear PET, and the labels include inks that can be washed off in a “typical PET recycling wash (caustic wash).” Id. at 11:44– 49; see also id. at 11:49–54 (describing embodiments in which the labels are free or substantially free of inks that cannot be washed off in a caustic wash or where the labels are free or substantially free of color plastics that cannot be recycled). The ’422 Patent further discusses “industry standards” for determining whether various embodiments of shrink labels are recyclable. See, e.g., id. at 11:29–53. For example, the Specification states that the “Association for Plastic Recyclers (APR) Critical Guidance Protocol for Clear PET Articles with Labels and Closures (PET-CG-02)” (Ex. 1005) can certify that a film is fully recyclable with a container or bottle. Id. at 11:34– 38. Additionally, the Specification states that labels “are recyclable according to the Evaluation of the Near Infrared (NIR) Sorting Potential of a Whole Plastic Article (SORT-B-01)” (Ex. 1010) and/or the “Evaluation of Sorting Potential for Plastic Articles Utilizing Metal, Metalized, or Metallic Printed Components (SORT-B-03)” (Ex. 1011). Ex. 1001, 11:39–44. The ’422 Patent further states that embodiments of the labels “are fully recyclable. For example, the labels may include inks that can be washed off in a typical PET recycling wash (caustic wash) and the polymers” are preferably clear PET. Id. at 11:44–48. The ’422 Patent thus provides various descriptions or standards to determine the recyclability of shrink labels. For the purposes of addressing the anticipation and obviousness grounds, we determine that any of these standards can be used to determine if a shrink label is “recyclable.” We note that our construction is preliminary and is based on the present record. We invite the parties to further the address the construction of “wherein the recyclable shrink label is recyclable with a PET container” during trial.” slip op. at 12

“We agree with Patent Owner that the desired signal and interferer signal must be received at the same time. The plain language of the claim requires the wireless transceiver to “receiv[e] a wireless signal having a desired signal and an interferer signal,” the determining of a signal strength of the interferer signal and the determining of a signal strength of the desired signal must be performed at the same time; otherwise, the determinations of signal strengths would not be of the same wireless signal. The specification supports this understanding. “When a receiver is actively receiving a desired signal, each block in the signal path has at its input the desired signal as well as noise and possibly interfering signals.” Ex. 1001, 5:20–22; see also id. at 5:31–33 (“FIGS. 2A and 2B illustrate examples of desired signals, interferers, and noise that may be received by one of the various circuits in a” slip op. at 21

“We agree with Patent Owner that Rauhala does not state that the signal strengths are measured simultaneously or at the same time. Indeed, as discussed above, Rauhala indicates unequivocally in the same paragraph the opposite—that detector DET provides to control unit 42 “an indication about either the receive channel signal strength RSS or the strength of any signal on the reception band.” Ex. 1004 ¶ 17. Rauhala describes that “control unit 42 provides two one-bit control signals cA and cM” based on indications received from detector DET. Id. Importantly, Rauhala indicates that “at the same time as” describes how the control unit 42 uses the received inputs RSS and RSSn shown in Figure 4, which are described earlier in paragraph 17 as indications of either RSS or RSSn from detector DET. Id. (“Signal cA is 0 when signal RSS is greater than S4 and signal RSSn is at the 11 Dr. Baker’s reply declaration correctly quotes Rauhala paragraph 17 but cites to paragraph 18. We deem this harmless error. same time smaller than Sn. . . . Signal cM is 1 when signal RSS is not greater than S4 and signal RSSn is at the same time at least Sn. Otherwise, signal cM is 0.”). The burden remains on Petitioner to demonstrate by a preponderance of the evidence that Rauhala discloses the disputed limitations as arranged or combined in the claim. Petitioner does not persuasively reconcile these “either/or” statements regarding the functioning of detector DET with the “at the same time as” statements regarding control signals output by control unit 42 in paragraph 17. We do not find persuasive Petitioner counsel’s position expressed at the hearing that Rauhala’s “either/or” statements are “simply an imprecise description” (Tr. 16:22–24).

“When asked at his deposition to explain Rauhala’s use of the word “or” regarding the functioning of detector DET, Dr. Baker asserted that “[detectors] can be designed to determine RSS or RSSn.” Ex. 2016, 85:5– 12. We find Dr. Baker’s testimony that “it’s reasonable that if you can design . . . the detector to detect one or the other, you can also design it to detect both” to be without factual support. Id. at 85:13–16. He points to no textbook or other independent evidence to support that would have led one of ordinary skill to design such a detector or to support that one of ordinary skill would have understood Rauhala’s detector to be so designed. Furthermore, Dr. Baker recognizes that “Rauhala doesn’t teach the details of what’s in the detector.” Id. at 91:6–7. We give little weight to Dr. Baker’s unsupported testimony that one could design a detector to detect both RSS and RSSn from the same wireless signal. See 37 C.F.R. 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”); see also Xerox Corp. v.

To the extent Petitioner asks us to consider the 01473 IPR institution decision for issue preclusion, we do not. In that decision the Board reached a finding based on the institution standard (showing of a “reasonable likelihood that the petitioner will prevail,” 35 U.S.C. § 314(a)) rather than proof by a preponderance of the evidence, which is before us now (35 U.S.C. § 316(e)). Ex. 1016. Thus, issues before us here were not presented and adjudged in that institution decision. Regarding the 01473 IPR adverse judgment decision, that decision did not require determination of any issues before us, as that decision was based on Patent Owner canceling the challenged claims rather than any determination regarding unpatentability that had been shown by a preponderance of the evidence. Ex. 1014. 2. Collateral Estoppel With Respect to the 00571 IPR We find and determine that the final written decision in the 00571 IPR, and the Federal Circuit’s CommScope decision affirming that decision, satisfies the conditions for applying collateral estoppel because the 00571 discloses materially the same claim limitations7 challenged here, and Patent Owner had full representation throughout the proceedings. Setting aside the factors of issue preclusion for a moment, our reviewing court’s affirmance of our final written decision in CommScope is persuasive authority that supports our prior construction of “packetizing” and Petitioner’s showing that Wu teaches the disputed packetizing limitations under that construction. In addition, issue preclusion prevents Patent Owner from re-litigating the issue of whether Wu teaches materially the same disputed limitation. See Pet.

“We disagree. Noting in the language of the claims requires that these method steps be performed by separate components, or that these method steps “provide two different channel indications at once” (Prelim. Resp. 38), only that they be performed as stated in the claim. In that respect, this case is distinguished from In re Robertson, where the Federal Circuit determined that the “third fastening means” required by the claims was not inherently disclosed by the prior art. Robertson, 169 F.3d at 745 (“The [prior art] patent does not expressly include a third fastening means for disposal of the diaper, as claim 76 requires.”). In further contrast to this case, Robertson addressed mechanical elements of a product (fasteners for disposable diaper), not steps in a process. More pertinent to our facts is the Federal Circuit’s decision in Microsoft Corporation v. Uniloc, 2017 LLC, No. 2021- 2039, 2022 WL 11531235 (Fed. Cir.

Circuit concluded that the Board had misconstrued the claims to require separate acts: We agree with [petitioner] that the Board misconstrued the claims to require that the comparing and determining step are performed by two separate acts in a certain order. Nothing in the intrinsic record requires such a narrow construction, and neither party presented this construction to the Board. Without any such evidence, we decline to impose such a narrow claim construction. Microsoft Corp., 2022 WL 11531235, at *3 (citation and footnote omitted).

“We are persuaded, on the present record, that both Petitioner’s and Patent Owner’s proposals are consistent with the problems and solutions in the ’825 patent and prior art of record. See In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995); Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). On balance, Petitioner’s proposal of education plus a minimum of two years of experience is a better reflection of the level of skill in the prior art. For example, Rauhala presents functional block diagrams of signal strength information. See, e.g., Ex. 1004, Figs. 1–5, ¶¶ 15, 17, 19, 21. Similarly, Masaaki’s Figure 1 shows “a circuit block diagram of a reception unit 40 of a pager” according to an embodiment of the invention. Ex. 1005, 5:3–4. The block diagram shows various components, including an antenna, amplifiers, bandpass filters, a mixer, an oscillator, and a detection circuit. Id. at 5:5–8, Fig. 1. Accordingly, we adopt Petitioner’s definition of the level of ordinary skill for purposes of this Decision. Our decision, however, would not change if we had applied Patent Owner’s proposed level of ordinary skill.” slip op. at 9

“strength indicator circuits 440 and 450, the written description unambiguously discloses that each circuit determines the cumulative signal level of the desired signal and the interfering signals. Neither circuit determines only the signal strength of the interferer signals, nor does a circuit determine only the signal strength of the desired signal. In other words, the written description does not support a limited reading of the claim language so as to require two separate circuits—one circuit for determining a a signal strength of the desired signal. Thus, based on this preliminary record, we do not construe the circuit limitation as requiring the wireless transceiver necessarily to have two circuits, one circuit for determining a signal strength of the interferer signal and a different circuit for determining a signal strength of the desired signal, because, under that reading of the claim, the only embodiment in the written description would not fall within the scope of the claim. It is well-established that “[s]uch an interpretation is rarely, if ever, correct and would require highly persuasive evidentiary support,” which is not present in this record as discussed below.

“As explained above, however, on this preliminary record, we do not interpret the circuit limitation to impose a timing requirement such that the determining has to occur at precisely the same time. Nor at this preliminary juncture do we read a precise timing requirement into the circuit limitation based on written description disclosure that the desired signal and the interferer signal are part of the received signal input spectrum. As explained above, for example, the written description describes a circuit providing a cumulative signal level corresponding to the sum of the desired and interfering signals. Ex. 1001, 6:59–67. As such, the written description describes making the determinations on two signals that are part of the received signal input spectrum. Patent Owner argues that Rauhala does not disclose “two determinations of two different signal strengths together.” Prelim. Resp. 40. We do not agree with Patent Owner on this preliminary record. Rauhala’s disclosure of providing control bits based on the comparisons of the signal strengths to respective thresholds, discussed above, also undermines Patent Owner’s argument that detector DET, which (i) provides one or the other and (ii) needs to be re-tuned to read the other signal, cannot anticipate the claim. Notably, for example, Rauhala discloses setting control bits based on comparisons of the respective signal strengths to thresholds: cM. Signal cA is 0 when signal RSS is greater than S4 and signal RSSn is at the same time smaller than Sn. Otherwise, signal cA is 1. Signal cA is taken to amplifiers Al and A2. Signal cM is 1 when signal RSS is not greater than S4 and signal RSSn is at the same time at least Sn. Ex. 1004 ¶ 17 (emphases added). Here Rauhala describes providing control signals based on the strength of both signals from the receive and neighboring channels, which undermines Patent Owner’s arguments.” slip op. at 25

“On the present record and for the purpose of this Decision, we agree with Petitioner that the proper construction of “communications unit” encompasses multiple DRUs or antenna units. Although Patent Owner is correct that not every embodiment needs to be reflected in every claim, and indeed, some embodiments may not appear in any claim, we do not agree that there is evidence supporting Patent Owner’s argument that the construction of “communications unit” should be narrowed to the embodiment requiring only one DRU/antenna. The cited claims do not indicate that multiple units may not transmit at the sets of frequencies recited. Additionally, although Patent Owner cites claim 16 as requiring that each communications unit is a single DRU, if that were a correct reading of claim 16, it is not clear what the claim recitation would add, as it would not narrow the prior recitation of a “communications unit” from claim 15. Such interpretations are disfavored. See Cat Tech LLC v. TubeMaster, Inc., 528 F.3d 871, 885 (Fed.

“In this case, Patent Owner’s assertion that its proposed construction is “consistent with the specification” fails to articulate or apply the proper standard. For example, any interpretation whose scope is equal to or narrower than a proper construction would logically be consistent with that proper construction. Thus, Patent Owner could only establish that its proposed interpretation is equal to or narrower in scope than the proper interpretation. Comparing the claims to prior art using a claim construction potentially narrower than what is claimed would not be a fruitful exercise because the claim could read on the prior art but not on the unduly narrow interpretation. Cf. Brown v. 3M, 265 F.3d 1349, 1351 (Fed. Cir. 2001) (holding that a broad claim is anticipated by any narrow disclosure falling within the broad claim). Patent Owner’s assertion that its proposed construction is consistent with examples in the specification is also not persuasive, and no more persuasive than its prior implication that its proposed construction is not inconsistent with the specification. i4i Ltd. P’ship v. Microsoft Corp., 598 F.3d 831, 843–44 (Fed. Cir. 2010) (“[A] claim is not limited to the embodiments described in the specification unless the patentee has demonstrated a clear intention to limit the claim’s scope with words or expressions of manifest exclusion or restriction.” (internal quotation omitted)). Similar to the situation in i4i, Patent Owner here has failed to explain how the claim is clearly limited to the examples in the specification. Instead, we construe “information of object” to be an identification of the object to be studied in the ultrasound examination, based on its plain language in the context of the claimed ultrasound device. We are not apprised of any language, on this record, in the ’157 patent or prosecution history that otherwise constrains what types of “object” would be inspected by the claimed device. For example, there is no indication that the machine is less capable than other ultrasound machines in a way that limits its use to examinations of certain things in a body such as a liver or a heart, but not simpler things in a body such as blood vessels or more complex things such as a fetus. Accordingly, we see no reason to constrain “object” to something other than those things in a body that a person of ordinary skill in the art would investigate during an ultrasound examination.” slip op. at 7
