A claim is unpatentable under 35 U.S.C. § 103 if the differences between the claimed subject matter and the prior art are such that the subject matter, as a whole, would have been obvious at the time the invention was made to a person having ordinary skill in the art to which the subject matter pertains. KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of underlying factual determinations, including: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of skill in the art; and (4) if in evidence, so-called secondary considerations.

“We do not agree with Petitioner that the fact pattern before us is analogous to Rembrandt. The rationale to combine the teachings of Inoue and Smith provided in the Petition focuses on replacing incandescent bulbs with LEDs, and includes the generic statement that “[t]he numerous record-supported advantages, set forth in Smith provide a clear motivation for use of the teachings of Smith as applied to Inoue, so as to enjoy the advantages set forth in Smith.” Pet. 47. The testimony in Dr. Schubert’s Declaration at pages 99–100 cited in support of Petitioner’s Reply arguments was not cited or otherwise referenced in the Petition. See Pet. 46–55. We find that the Petitioner’s Reply is not responsive to the Institution Decision and is improper because it presents a new rationale to combine the teachings of Inoue and Smith that was not expressed in the Petition. See 37 C.F.R. § 42.23; CTPG § II.I. Petitioner could have presented its rationale to make out a prima facie case of unpatentability in the Petition. See 37 C.F.R. § 42.23; CTPG § II.I. Accordingly, we do not consider Petitioner’s new rationale to combine the teachings of Inoue and Smith presented for the first time in the Reply. Based on the entire record, but not including Petitioner’s new rationale and newly cited support to Smith and Dr. Schubert’s testimony (Exs. 1013, 1017) presented for the first time in the Reply, we are not persuaded that Petitioner sets forth in the Petition sufficient articulated reasoning with rational underpinning to support the conclusion that it would have been obvious to one of ordinary skill in the art to modify the circuit of Inoue to include a light source or LED light source with a twinkling or flashing effect in view of Smith’s teachings. See Pet. 46–47, 49–50, 51–53, 55. Accordingly, we determine that Petitioner has not demonstrated by a preponderance of the evidence that the subject matter of independent claim 9 and dependent claims 3, 5, and 6 would have been obvious over the teachings of Inoue and Smith.” slip op. at 32

“Based on Petitioner’s citations to Holler, Inoue, and Dr. Schubert’s testimony (Ex. 1013), we are persuaded Petitioner sets forth sufficient articulated reasoning with rational underpinning to support the conclusion that it would have been obvious to one of ordinary skill in the art to “use the resistive value as taught by Holler in the circuit of Inoue to control the illumination of the light sources so that the other illumination devices in the serial light string will not go dark or change illumination if one of the LEDs fails or becomes disconnected.” Pet. 27; see KSR, 550 U.S. at 418. Based on the entire record and including the reasons explained above in Section II.D.2. addressing anticipation of claim 1 by Inoue, we determine Petitioner shows by a preponderance of the evidence that the subject matter of claims 1 and 10 would have been obvious over Inoue and Holler.

“We observe that, aside from Declaration testimony of Mr. Altamura and accompanying exhibits, Patent Owner does not offer any additional evidence to establish reduction to practice. An inventor’s testimonial assertion of inventive facts requires corroboration by independent evidence. Brown v. Barbacid, 276 F.3d 1327, 1335 (Fed. Cir. 2002). The purpose of the corroboration requirement is to prevent fraud, by providing independent confirmation of the inventor’s testimony. Kridl v. McCormick, 105 F.3d 1446, 1450 (Fed. Cir. 1997). Without the requirement of independent corroboration, there would be a great temptation to commit perjury and the adverse party would be effectively precluded from a successful rebuttal. Price v. Symsek, 988 F.2d 1187, 1194–95 (Fed. Cir. 1993). A rule of reason applies to determining whether the inventor’s testimony has been corroborated. See id. at 1195. “The rule of reason, however, does not dispense with the requirement for some evidence of independent corroboration.” Coleman v. Dines, 754 F.2d 353, 360 (Fed. Cir. 1985). Accordingly, based on the entire record, we find that Mr. Altamura’s Declaration testimony is uncorroborated.

“On this record, we determine that the recitation “to achieve continuous presentation” is limiting and requires an amount of continuous (uninterrupted) playback/presentation after an upshift or downshift. The specification describes agent controller 702 determining whether to upshift based on a trigger threshold Θup, which itself is based on various factors including a current read ahead margin and a minimum safety margin. See Ex. 1001, 17:44–58. If agent controller 702 can sustain upshift quality, then it will upshift and request higher quality streams. See id. at 17:58–61. Conversely, when an upshift is not possible, agent controller 702 determines whether to downshift based a different threshold Θdown, which itself is based on the same sort of factors. See id. at 18:4–7. When the stream quality is not adequate, it downshifts. See id. at 18:7–14. These disclosures are similar to the language of claim 12, which recites “repeatedly generating a factor indicative of a current ability to receive the digital content at a rate sufficient for presenting the digital content as the digital content is received, . . . wherein the factor relates to a performance of the network” and “making the successive determinations whether to change the requested bit rate based on the factor to achieve continuous presentation of the digital content using the individually-requestable portions of the highest bit rate one of the copies determined receivable at that time.” Ex. 1001, 20:5–16 (emphasis added). That is, claim 12 refers to “achiev[ing] continuous presentation” based on what is “sufficient for presenting the digital content,” trading quality to ensure continuous playback.” slip op. at 14

“server comprises at least two servers and wherein at least one streamlet is requested from a first of the at least one server and at least one other streamlet is requested from a second server of the at least one server other than the first server.” Ex. 1001, 19:7–12. Petitioner references its mapping of the “at least one server” in claim 1 to Leaning’s server 1. Pet. 20 (citing Ex. 1004, 2:15–16, 2:18–22, 2:31–32, 5:8–14, Fig. 1), 23 (citing Ex. 1004, 6:13–26, 9:3–7, 16:6–12), 37; see supra §§ II.D.2.b–c. Petitioner contends that, “[t]o the extent Leaning does not disclose at least two servers wherein one sub-file (streamlet) is requested from a first server and another sub-file (streamlet) is requested from a second server such an arrangement would have been obvious in view of the knowledge of a [an ordinarily skilled artisan].” Id. at 37. Citing the common nature of such an arrangement, Petitioner contends that an ordinarily skilled artisan would have been motivated to provide multiple web servers containing the same sets of sub-files for streams in order to have redundancy in the system and allow for clients to establish connections with multiple servers and request a first sub-file from a first web server and, if the connection between the first web server becomes congested or the first web server otherwise fails or becomes unavailable, request a subsequent sub-file from the second web server. Id. at 37–38 (citing Ex. 1003 ¶ 85; Ex. 1012, 108,5 Fig. 4-11). Patent Owner does not dispute Petitioner’s analysis for claim 3. We are persuaded that it would have been obvious to implement Leaning’s server 1 as two servers that store different streamlets based on Dr. Houh’s uncontested testimony about system redundancy. See Ex. 1003 ¶ 85. His testimony is backed by a contemporaneous reference about HTTP that shows requests for different objects from different servers over parallel TCP connections. See, e.g., Ex. 1012, 108–09, Fig. 4-11. Thus, we determine that Petitioner has shown, by a preponderance of the evidence, that the subject matter of claim 3 would have been obvious over Leaning.” slip op. at 34

“Patent Owner does not address the level of skill. See Prelim. Resp.

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.

See PO Resp. 8–9. It is well settled that it is improper to read an extraneous limitation into a claim from the specification. See e.g., Commark Comm’s Inc. v. Harris Corp., 156 F.2d 1182, 1186 (Fed.

“3. “Inherent Resistance” Claim 10 uses the term “inherent resistance of the light source to which the light resistor is attached.” See Ex. 1001, 14:46–48. Petitioner asserts that “there is no ‘inherent resistance’ of an LED, but only the resistance of the LED at any particular operating current flowing through, and voltage across, the LED.” Pet. 21 (citing Ex. 1013, 29 ¶¶ 6–9). Petitioner also points out that the term inherent is not used in the ’794 Patent Specification. See id. Patent Owner does not explicitly address “inherent resistance” in terms of a claim construction. See Prelim. Resp. 6–9. In any event, when addressing an alleged lack of motivation to combine the teachings of the references, Patent Owner compares and contrasts incandescent bulbs, which according to Patent Owner, have an inherent resistance, and LEDs, which according to Patent Owner, do not exhibit self-regulating resistance. See Prelim. Resp. 20 (citing Ex. 2002 ¶ 67); see also id. at 23 (similar argument, citing Ex. 2002 ¶ 73). Indeed, Patent Owner asserts that “the word resistance is not useful when describing LEDs as opposed to incandescent bulbs. . . . LED lights have an exponential current vs. voltage relationship . . . rather than a linear current vs. voltage relationship as found in a simple resistance, such as seen in incandescent light bulbs.” Id. at 20 (citing Ex. 2002 ¶ 66). For the purpose of institution, we understand the term “inherent resistance” to mean the resistance at a particular operating current or voltage across the LED light source.

In substance, the parties’ dispute appears to concern whether the plain language of the claims requires that a recited function must be performed only after or in response to expiration of a threshold (and other prerequisites), as opposed to requiring a function that begins before and continues after expiration of a threshold. Notably, dependent claim 3 recites: “The electronic device of claim 1, wherein the electronic device is configured such that the first feedback that is perceptible by touch is output prior to the display of the menu.” Ex. 1001, 104:1–4 (emphasis added). Given that independent claim 1 is necessarily broad enough to include claim 3, it seems on this record that the functions recited in Limitation [1.o] necessarily can happen at different times, as opposed to, for example, only responses that are triggered by the so-called “prerequisite elements.” We encourage the parties to address this issue as a matter of claim interpretation in future briefing. Based on the current record, however, we determine that it is not necessary to provide an express interpretation of any claim terms at this stage of the proceeding. See Realtime Data, LLC v. Iancu, 912 F.3d 1368 (Fed. Cir. 2019) (“The Board is required to construe ‘only those terms . . . that are in controversy, and only to the extent necessary to resolve the controversy.’” (quoting Vivid Techs., Inc. v. Am.

“The two proposals are materially similar in the education requirement, but differ marginally in professional experience required (three versus five years). See supra. While we were persuaded, on the preliminary record, that both Petitioner’s and Patent Owner’s proposals were consistent with the problems and solutions in the ’202 patent and the prior art of record, on balance, we determined that Petitioner’s proposal was a better reflection of the level of skill in the prior art, and we therefore adopted it for our Institution Decision. See Institution Dec. 12–13. For this Decision, we adopt the description of the person of ordinary skill articulated by Petitioner and used previously in our Institution Decision. In light of our review of the complete record, we find that this formulation is consistent with the ’202 patent, the prior art of record, and is supported by the testimony of Dr. Baker.

“requirement.” Pet. Reply 5. We do not agree with Petitioner. We find that the language of the claims supports Patent Owner’s argument that the desired signal and the interferer signal are received together. As discussed infra, claim limitations 7.7 and 7.8 recite determining a signal strength of the interferer signal and determining a signal strength of the desired signal. These determinations must be performed at the same time; otherwise, the determinations of signal strengths would not be of the same wireless signal. See Larson II Decl. ¶ 70; Baker II Decl. ¶¶ 48–49 (explaining that consideration of signal strengths detected at the same time would be “essential”). The specification of the ’202 patent further supports this finding: “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, 5:22–24; see also Figs. 2A, 2B (showing interferer signals and desired signals together).” slip op. at 17

“As discussed above, Fintiv factors 2, 3, and 5 favor denial. Factor 1 is neutral, and only factor 4 weighs against denial. Thus, we determine that the first five Fintiv factors favor discretionary denial, and we now assess compelling merits. CommScope, Paper 23 at 5 (“In circumstances where, however, the Board’s analysis of Fintiv factors 1–5 favors denial of institution, the Board shall then assess compelling merits.”). According to the Guidance Memo, the compelling merits standard is met when “the evidence, if unrebutted in trial, would plainly lead to a conclusion that one or more claims are unpatentable by a preponderance of the evidence.” Guidance Memo, 4. A challenge can only meet this standard “if it is highly likely that the petitioner would prevail with respect to at least one challenged claim.” OpenSky Indus., LLC v. VLSI Tech.

“c. Summary In view of the foregoing, we determine that Petitioner’s obviousness challenges based on Lee do not meet the compelling merits standard with respect to claim 1. Petitioner does not rely on Kim to teach the recited “predetermined time from the transmission of the deactivation message.” See Pet. 34–37, 48–55 (relying on Kim for limitation “stopping downlink (DL) transmission of the secondary carrier and initializing uplink (UL) and DL retransmission buffers after transmitting the deactivation message”). Claims 2–4 depend from claim 1. Petitioner’s contentions regarding these dependent claims rely on the same analysis for the limitation of claim 1 discussed above. See Pet. 55, 57, 60. Accordingly, we also determine that Petitioner’s obviousness challenges based on Lee do not meet the compelling merits standard with respect to claims 2–4.” slip op. at 30

“system are best served by denying or instituting review” when evaluating these factors. Fintiv, Paper 11 at 6. We have considered the circumstances and facts before us in view of Fintiv factors 1–5. As discussed above, factor 1 is neutral, factors 2, 3, and 5 weigh in favor of discretionary denial of institution, and factor 4 weighs slightly against discretionary denial. We, therefore, conclude that the evidence of record on factors 1–5 favors exercising our discretion to deny institution of an inter partes review. Accordingly, following CommScope, we must address the merits of the Petition to determine whether they are compelling. The Guidance Memo states that “[c]ompelling, meritorious challenges are those in which the evidence, if unrebutted in trial, would plainly lead to a conclusion that one or more claims are unpatentable by a preponderance of the evidence.” Guidance Memo, 4.

“As noted above, our inquiry is directed to whether the Petition meets the compelling merits standard, not the “reasonable likelihood” standard of § 314(a). On this record, we agree with Patent Owner. Claim 1 recites “changing the secondary carrier to a deactivation state based on a predetermined time from the transmission of the deactivation message.” To illustrate, Figure 10 of the ’662 patent is reproduced below. Figure 10 is a diagram of a carrier state management method. Ex. 1001, 4:49–50. The ’662 patent teaches that “the base station performs the step . . . of transmitting the deactivation message to the terminal at a time t1.” Id. at 13:50–52. The ’662 patent further teaches that “[t]he base station may perform the step . . . of changing state information for a secondary carrier that is managed by the base station to the deactivation state at a time t5 after the lapse of a predetermined time (t5–t1).” Id. at 13:60–63. As discussed above, Petitioner argues that Lee’s disconnection time corresponds to the recited “predetermined time.” Pet. 43. To satisfy the limitation of claim 1 under this theory, Petitioner must show that Lee’s disconnection time is the time from the transmission of the AAI_CM-CMD” slip op. at 30
