      “The ’558 specification and the context of claims 6, 8, and 13 and the related language of claim 10 support that the “source” must be able to receive both the boosted supply voltage and the first supply voltage (a selective boost). PO Resp. 35–38; Ex. 1201, 1:42–50, 5:31–49, 8:55–62, 8:62–9:17, 9:21–36, 10:19–29, Figs. 3 and 5. Accordingly, we do not agree with Petitioner that the use of a conditional “or” in claim 10 indicates that only one voltage is necessary to meet the claims. Pet. Reply 3–9. We credit Patent Owner’s evidence and arguments that the language of claims 10 and 11 and the ’558 patent specification support that claim 10, like dependent claim 11, require a selective boost. See PO Resp. 26–29. Petitioner’s arguments assert both that Patent Owner improperly limits the construction to one disclosed embodiment and that the Patent Owner’s construction improperly excludes a disclosed embodiment. Pet Reply 6–8. We are not persuaded by Petitioner’s argument that Patent Owner’s construction should be rejected because it excludes an embodiment. Pet. Reply 6 (citing EPOS Techs. Ltd. v. Pegasus Techs. Ltd., 766 F.3d 1338, 1347 (Fed. Cir. 2014); Anchor Wall Sys., Inc. v. Rockwood Retaining Walls, Inc., 340 F.3d 1298, 1308 (Fed. Cir. 2003); Dow Chem. Co. v. Sumitomo Chem.

Co., 257 F.3d, at 1378; Anchor Wall Sys., 340 F.3d at 1308. Petitioner provides no persuasive evidence that the embodiment they identify as being excluded is the preferred embodiment of the ’558 patent. Further, Petitioner cites no support that claims 10 or 11 must be construed to cover all embodiments. See Baran v. Med. Device Techs., Inc., 616 F.3d 1309, 1316 (Fed. Cir. 2010). The Federal Circuit has stated that the broadest reasonable construction is not required to cover the most embodiments in a patent specification, but “must be reasonable in light of the claims and specification. The fact that one construction may cover more embodiments than another does not categorically render that construction reasonable.” PPC Broadband, Inc. v. Corning Optical Commc’ns RF, LLC, 815 F.3d 747, 755 (Fed. Cir. 2016). We are not persuaded by Petitioner’s argument that exclusion of a single embodiment renders Patent Owner’s claim construction improper.” slip op. at 12

      “persuasive. We credit Petitioner’s argument and evidence regarding the Chu and Choi 2010 concerns with power degradation and efficiency, which Patent Owner’s declarant testified were common concerns known before the ’558 patent. Pet. Reply 11–12 (citing Ex. 1330, 13:12–20, 13:21–14:2, 259:7–18); Ex. 1027 ¶ 18. We find that Petitioner presents persuasive evidence and argument that the issues of power degradation and efficiency were known in the art and within the knowledge and skill of a person of ordinary skill in the art. See id.; see also PO Resp. 32–33 (noting that “Patent Owner does not contest that efficiency and output distortion/robustness problems were generally known in the art.”). We also find that Petitioner identifies persuasive motivations to combine from the references themselves, identifying specific teachings in Choi 2010 in reference to boost converter systems like those in Chu. Pet. 57–58 (citing Ex. 1306, 1074, 1077). Indeed, Patent Owner’s declarant, Dr. Kelley, agreed that Choi 2010 teaches the use of boost converters to address battery degradation. Ex. 1030, 105:20–106:4, 156:3–6. Finally, Petitioner provides evidence that degrading battery performance affecting operation further motivates the combination of Chu and Choi 2010. Ex. 1030, 165:17–22; Pet. 57–61. We are also persuaded by Petitioner’s citation to secondary references of examples that use a boost converter to prevent distortion provides further support that a person of ordinary skill in the art would have been motivated to combine Chu with Choi 2010 and Hanington. See Pet. 58–60 (citing Ex. 1318, code (57); Ex. 1315, 8); Ex. 1303 ¶¶ 109–111. Patent Owner’s arguments regarding the secondary references attempts to bodily incorporate the teachings from these references into Chu and Choi 2010. Patent Owner also fails to address persuasively the support for the teachings these secondary references provide for modifying Chu’s supply modulator to incorporate a boost converter as disclosed in Choi 2010 and Hanington. Pet. 58–60 (citing Ex. 1318, code (57); Ex. 1315, 8); Ex. 1303 ¶¶ 109–111. Indeed, Patent Owner’s declarant agrees extending battery life, which is discussed in Exhibit 1315 and cited by Petitioner as a motivation to combine Chu and Choi 2010 (Pet. 58–60), would be achieved by the combination of Chu and Choi 2010 and was within the ordinary skill of an artisan. Ex. 1330, 281:6–282:2, 284:6–12. We also disagree with Patent Owner that the Petition fails to show how to combine the references to solve the conflicting problems that Petitioner alleges as motivation—efficiency and degradation. PO Resp. 33– 35. First, we credit Dr. Kelley’s testimony that the result of the combination was within the knowledge and skill of an artisan. Ex. 1330, 105:20–106:4, 156:3–6, 281:6–282:2, 284:6–12. Second, we find that the evidence and argument in the Petition explain sufficiently how Chu would have been modified to incorporate the boost supply voltage of Choi 2010 and Hanington and that such modifications involve typical and well known components widely used in boost converters. See Pet. 68–70; Ex. 1303 ¶¶ 112–113, 126–127; Ex. 1329 ¶ 24.” slip op. at 21

      “Owner argues “Choi 2010’s boost is a constant boost applied to the linear amplifier, and thus teaches away from a selective boost.” PO Resp. 39. Patent Owner further argues combining Myers’ selective boost with Choi 2010’s constant boost would destroy the purpose and benefits of Choi 2010’s design. Id. at 43. We do not find that Choi 2010’s use of a constant boost teaches away from selective boost in Myers. Patent Owner’s evidence and argument do not persuade us that Choi 2010’s teachings of boost exclude or discourage the use of selective boost. The portion of Choi 2010 Patent Owner cites does not criticize or discourage the use of selective boost, but applies boost generally to achieve its goals. See Ex. 1306, 1333–1334. We do not find that the teachings in Choi 2010 discourage a person of ordinary skill in the art from working with boosted voltage to achieve battery efficiencies. See Galderma Labs., L.P. v. Tolmar, Inc., 737 F.3d 731, 738 (Fed. Cir. 2013). Choi 2010 does not discredit or criticize selective boost to improve efficiency.” slip op. at 23

      “the ITC investigation (see Ex. 2001, 36–37), Petitioner does not assert the direct incorporation of Myers technology into the combination of Chu and Choi 2010/Hanington. Instead, Petitioner asserts that Myers teaches a method of choosing a power source to improve operation efficiency. Pet. Reply 22–23; Pet. 72–76; Ex. 1312, 9:18–21, 1:19–23. Furthermore, Patent Owner’s declarant, Dr. Kelley, acknowledges this teaching. Ex. 1330, 270:13–271:5. Petitioner’s arguments and evidence differ materially from those cited in the ITC investigation. See Ex. 2001, 36–37. In the case before us, Petitioner does not directly incorporate Myers hardware into Chu or Choi 2010 and Hanington, but asserts that Myers— particularly Figure 7 that discloses the technique of switching between two different power sources—teaches a technique that would have been within the level of skill of an artisan at the time of patenting. Pet. Reply 23; see Pet. 72–76; Ex. 1330, 283:16–284:1; see also Ex. 1330, 152:21–153:4 (agreeing that a person of ordinary skill would have known how to select between two power sources). Contrary to the combination of the envelope elimination and restoration (EER) circuits of Myers into the linear amplifiers of Chu and Choi 2010 argued at the ITC, Petitioner has provided testimony and citations to the record that Myers’s selection functionality is applicable to the combination of Chu and Choi 2010. We credit Petitioner’s argument and evidence that a person of ordinary skill in the art would have been motivated to combine Chu, Choi 2010, and Hanington with the technique from Myers and would have had a reasonable expectation of success in doing so. Pet. 79–81 (providing supporting argument and testimony regarding battery and boosted voltage efficiency as taught by Myers). We find that Petitioner’s argument and evidence provide sufficient rationales with articulated reasoning to support the application of the Myers selection technique with the amplifiers of Chu and Choi 2010 to achieve battery efficiency during described operating modes. Pet. 57–61 77–82. Indeed, Dr. Kelley’s testimony supports the applicability of the techniques in Myers. See Ex. 1330, 270:13–271:5, 281:6–282:2, 284:6–12; Ex. 1312, 9:18–21 (discussing Myers’ teaching of choosing power source for operation efficiency). Based on our review of the full record, Petitioner demonstrates by a preponderance of the evidence an articulated rationale with articulated reasons to combine Chu, Choi 2010, Hanington, and Myers. In addition, Petitioner demonstrated by a preponderance of the evidence that Chu, Choi 2010, Hanington, and Myers teach the limitations of dependent claim 11.” slip op. at 24

      “and the specification to determine whether they expressly or implicitly require a specific order. See Altiris, 318 F.3d at 1369–70. Here, we agree with Patent Owner that the language shows that the results of a step are used in the next step; that is, “step 7[b] ‘preparing to transmit a particular payload type in a timeslot’ [comes before] step 7[c] ‘determining whether the timeslot is a current desired timeslot for the TDMA system,’ because the transmitting device looks at the ‘the timeslot’ identified in the ‘preparing’ step to ‘determin[e]’ whether that timeslot is ‘a current desired timeslot.’” PO Sur-Reply 3–4 (quoting Ex. 1001, cl. 7).” slip op. at 13

      “We agree with Patent Owner that the ordered steps 7[c] to 7[e] require transmitting on an alternate timeslot, that is, a timeslot that is not an assigned timeslot. PO Resp. 7–9. The plain language of claim 7 states that the preparing step of limitation 7[b] is for “a timeslot,” indicating that it is broader than the assigned timeslot of the TDMA system. In limitation 7[c], the claim expressly requires a determination of whether the timeslot in the preparing step is the “current desired timeslot” (assigned timeslot) and selecting (limitation 7[d]) the appropriate synch pattern. The “selecting” step of claim 7[d] requires: “if the timeslot is the current desired timeslot, select[] a synchronization pattern selected from the first set of synchronization patterns . . . otherwise select[] a synchronization pattern selected from the second set of synchronization patterns . . . .” The synchronization pattern that is selected in limitation 7[d] is then used during transmission in limitation 7[e]. Thus, although the claims and specification do not explicitly refer to an alternate timeslot, the claim requires transmitting on the timeslot that is not the current desired timeslot (assigned timeslot).

      “arguments are directed to products produced by Petitioner, rather than by Patent Owner, products that were found in an Initial Determination (“ID”) of the International Trade Commission (“ITC”) to infringe challenged claims 7 and 8 of the ’991 patent. Ex. 2009, 192–202. In addition, the Administrative Law Judge in that ID found that Petitioner intentionally copied Patent Owner’s patented technology. Id. at 226–228. That finding was based, in part, upon an adverse inference drawn from the repeated invocation of the Fifth Amendment when former employees of Patent Owner were questioned about allegations that they downloaded confidential documents of Patent Owner shortly before becoming employed by Petitioner. Id. at 241–242 (citing LiButti v. United States, 107 F.3d 110, 123–24 (2d Cir. 1997)). In addition to Patent Owner’s detailed discussion of how Petitioner’s products embody all limitations of the challenged claims, these specific administrative findings support Patent Owner’s position that there is sufficient nexus between its evidence and the challenged claims.

      “We are not persuaded by this argument. Petitioner’s arguments go to the weight that should accorded to the ID, not to its admissibility. See Liquid Dynamics Corp. v. Vaughan Co., 449 F.3d 1209, 1221 (Fed. Cir. 2006) (“Vaughan’s challenge goes to the weight of the evidence rather than the admissibility of Lueptow’s testimony and analysis.”). As Patent Owner responds, the ITC “determined not to review the portions of the ID’s findings regarding the ’991 patent.” Paper 43, 4. And we agree with Patent Owner that Petitioner’s argument that the Final Determination is subject to approval by the President lacks merit because the President did not act on the Final Determination within the period specified by 19 U.S.C. § 1337(j)(2). Id. at 4–5. The ID recounts evidence that has been considered and evaluated by an objective and disinterested judge, and articulates findings that are relevant to whether there is a sufficient nexus between the challenged claims and Patent Owner’s evidence regarding Petitioner’s products. The ID is also relevant to the issue of copying by Petitioner. Although Petitioner asserts that the ID is prejudicial or confusing, it provides insufficient argument to support those assertions. With respect to Exhibits 2010, 2012–2019, and 2021, Petitioner contends that these exhibits are Hytera advertising and marketing documents, which do not supply sales numbers or third-party praise to prove commercial success. Paper 40, 3–4. Again, this argument relates to the weight to be accorded to that evidence, not to its admissibility. As we note above, we agree with Petitioner that these factors impact the appropriate weight to be accorded to the evidence, and we have accounted for that impact. Finally, we deny Petitioner’s request that Exhibit 2020 should be excluded under Fed. R. Evid. 401 and 402 because Patent Owner’s demonstrative slides in Exhibit 2020 rely on Exhibits 2010, 2012–2019, and 2021.

      “We are persuaded that our preliminary interpretation of “session” in our Decision on Institution is, at least in some respect, overly broad. Independent claims 1, 6, 7, and 10 each refer to “sessions” in plural, and independent claim 7 refers to “simultaneous” sessions. Thus, the term “session” must be understood, at least, in such a manner as to allow multiple sessions to be distinguished from one another. Although independent claim 5 does not recite “sessions” in plural, the same term should be construed consistently across all claims. Accordingly, we conclude that there must be sufficient delineation within a proper construction of “session” that separates a “session” between one client and one server and a different “session” when one of the client and server are replaced, and that separates multiple sessions from each other even between the same pair of client and server. During Oral Hearing there were extensive discussions regarding proper construction of “session.” See Tr. 7:9–22:18, 43:11–65:15, 74:21–76:13. At Oral Hearing, counsel for Petitioner agreed that “session” should be understood as communications having a recognizable beginning and a recognizable end.

      “We agree with Patent Owner that Petitioner has failed to identify what constitutes a “session” in Feinberg in accordance with a proper construction of “session.” That proper construction of “session” is set forth above and has been agreed to by the parties.

We state it again here: “a set of transmitters and receivers, and the data streams that flow between them wherein each data stream flowing between the transmitters and receivers has a recognizable beginning of the data stream transmission and a recognizable end of the data stream transmission.” Petitioner identifies Feinberg’s disclosure of forwarding (shunting) received requests from the primary server to secondary servers (for purposes of load balancing) teaches the recited “communication between the main server and agent server enlists additional agent servers to support incremental secure sessions in response to maintaining performance at a desired level.” Pet. 21–23 (emphasis added).

      “We are persuaded that our preliminary interpretation of “session” in our Decision on Institution is, at least in some respect, overly broad. Independent claims 1, 6, 7, and 10 each refer to “sessions” in plural, and independent claim 7 refers to “simultaneous” sessions. Thus, the term “session” must be understood, at least, in such a manner as to allow multiple sessions to be distinguished from one another. Although independent claim 5 does not recite “sessions” in plural, the same term should be construed consistently across all claims. Accordingly, we conclude that there must be sufficient delineation within a proper construction of “session” that separates a “session” between one client and one server and a different “session” when one of the client and server are replaced, and that separates multiple sessions from each other even between the same pair of client and server. During Oral Hearing there were extensive discussions regarding proper construction of “session.” See Tr. 7:9–22:18, 43:11–65:15, 74:21–76:13. At Oral Hearing, counsel for Petitioner agreed that “session” should be understood as communications having a recognizable beginning and a recognizable end. Id. at 10:13–16 (“Of course a session has a beginning and an end. I think that is axiomatic in a session. I think that is how Dr. Rubin defined it in his declaration”); see also id. at 12:21–13:5, Ex. 1005 ¶ 41.

Tr. 10:13–16, 53:13–54:10. We state it again here: “a set of transmitters and receivers, and the data streams that flow between them wherein each data stream flowing between the transmitters and receivers has a recognizable beginning of the data stream transmission and a recognizable end of the data stream transmission.” Petitioner identifies Feinberg’s disclosure of forwarding (shunting) received requests from the primary server to secondary servers (for purposes of load balancing) teaches the recited “communication between the main server and agent server enlists additional agent servers to support incremental secure sessions in response to maintaining performance at a desired level.” Pet. 21–23 (emphasis added).

Petitioner had ample notice of the possibility of a narrower interpretation of “session.” See PO Resp. 7–11, 23–24.

Nevertheless, Petitioner’s Reply still does not specifically identify a “session” within Feinberg that accounts for what constitutes a session in Feinberg, including when it begins and ends. Claim 10 recites, in pertinent part, “sharing spare CPU cycles of the computer network for encrypting and decrypting communication to provide N simultaneous secure session[s] among said network of computers.” Petitioner’s analysis with respect to the recitation of “N simultaneous secure session[s]” is deficient for the same reasons we discussed above with respect to the recitation of “incremental secure sessions” in claim 6.

See In re Merck & Co., 800 F.2d 1091, 1097 (Fed. Cir. 1986). Furthermore, “the [obviousness] analysis need not seek out precise teachings directed to the specific subject matter of the challenged claim, for a court can take account of the inferences and creative steps that a person of ordinary skill in the art would employ.” KSR, 550 U.S. at 418. “If a person of ordinary skill can implement a predictable variation, § 103 likely bars its patentability.” Id. at 417. Yabe discloses multiple embodiments and expressly discloses interchangeability of rotary (“surface-sequential-type”) filters as disclosed in Yabe’s second embodiment (Figure 2) and mosaic (“built-in”) filters as disclosed in Yabe’s first and third embodiments (Figures 1a and 10). Ex. 1007, 18:17–21. Yabe’s express disclosures outweigh the unsupported assertions of Patent Owner’s expert regarding the complexity of constructing the proposed combination of embodiments. “Combining two embodiments disclosed adjacent to each other in a prior art patent does not require a leap of inventiveness.” Boston Sci.

      “We are disinclined to adopt Patent Owner’s proposed construction of this phrase, as recited in claim 1, to require mathematical manipulation. Claim 1 recites “calculates” in a self-defining manner, specifically reciting calculating the image signals “by minimizing the contribution from signals produced by the image sensor in response to red illumination light.” Thus, claim 1 is clear on its face that the calculation to be performed is by minimizing the contribution from red light. Therefore, our analysis shifts to determining the meaning of “minimizing” as recited in claim 1. The ’151 patent discloses a variety of embodiments for “minimizing” the contribution of red light.5 For example, in support of the Patent Owner’s 5 Additionally we observe that “minimizing” appears only once in the ’151 patent—in claim 1 (and, thereby, also in its dependent claims 2–9). construction, the ’151 patent does disclose exemplary embodiments that minimize red light contribution utilizing mathematical manipulations including, for example, CMYG filter computations that are “considered to be well known to those of ordinary skill in the art” (Ex. 1001, 4:66–7:59) and averaging blue and green signals to “compute” a cyan signal (id. at 4:21–24). The ’151 patent, however, also specifically recites, Because the passbands of the red mosaic filters do not significantly overlap with the pass bands of the other filters for a short wavelength imaging mode, the contribution of the image signals due to red illumination light can be reduced or largely eliminated by not assigning the image signals produced by image sensor pixels that are sensitive to red light to their corresponding display pixels. Id. at 4:5–12 (emphasis added). The ’151 patent further states “a short wave-length image (or the color components of such an image) can be computed from a subset of image sensor signals (i.e. excluding the signal data from red light).” Id. at 8:29–32 (emphasis added). Thus, the ’151 patent also encompasses the contribution of red light in the image being” slip op. at 12

      “Although the ’151 patent does not address “analog” or “digital” in reference to “memory,” we agree with Patent Owner, based primarily on the cross-examination testimony of Petitioner’s expert, Mr. Gunday, that the ordinarily skilled artisan at the time of the ’151 patent filing would have understood “memory,” in the context of the ’151 patent, to be referring to digital memory rather than analog buffers. The signals stored in Krauter’s analog buffers are transitory, analog signals propagating from circuits that calculate a value, through the analog buffer, to an analog input of a display monitor. We are persuaded that an ordinarily skilled artisan would not have considered such analog buffers to be a memory in the context of the ’151 patent. Thus, we determine “memory,” as recited in claim 1, means any digital memory capable of storing image signals that minimize the contribution of red light.” slip op. at 17

      “The definition of “advice” is “information or notice given.” Ex. 3001 (Webster’s Third New International Dictionary 32 (1971), 3.). Thus, the plain and ordinary meaning of “maintenance advice” is consistent with the aforementioned evidence, in that “maintenance advice” can include maintenance information, but does not require “recommended maintenance actions.” Patent Owner argues that this dictionary definition cited by the Board includes an alternative definition of “advice” as a “recommendation regarding a decision or course of conduct.” PO Resp. 33 (citing Ex. 3001, 3). Patent Owner further argues that this alternative definition of “advice” is most consistent with specification. PO Resp. 33.

Pet. 30. Petitioner adds that ARINC 624-1 provides an explicit motivation to utilize Ward’s ground based maintenance analysis software in implementing its maintenance system, because ARINC 624-1 states that “if known in advance of an airplane’s arrival at a terminal, selected information held in the OMS central maintenance computer’s memory could be useful to line maintenance personnel in planning timely corrective action.” Pet. 30–31 (quoting Ex. 1014 § 2.2.4).

Id. We do not agree with Petitioner’s argument that claims 4 and 8–10 require a flight data recorder on the ground, as claim 4 merely recites a “central station” “configured to receive and analyze said digital aircraft performance.” We do agree, however, with Petitioner’s argument that the express language of independent claim 4 requires “an aircraft having a flight data recorder.” Furthermore, claim 4 requires that the “digital aircraft performance data,” which the “central station” is configured to receive and analyze, is “data directed to the flight data recorder.” Thus, the invention recited in independent claim 4, and its dependent claims, must include a flight data recorder onboard the aircraft and, separately, a central station configured to receive and analyze data directed to the onboard flight data recorder. 10 The recitation “[a]n aircraft maintenance system for use on an aircraft having a flight data recorder” appears in the preamble of claim 4. “In general, a preamble limits the invention if it recites essential structure or steps, or if it is ‘necessary to give life, meaning, and vitality’ to the claim.” Catalina Marketing Int’l., Inc. v.
