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. Yu is prior art to the ’252 Patent because Patent Owner is unable to establish actual reduction to practice earlier than the July 31, 2006, filing date of Yu.” slip op. at 51

“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.

“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. A challenge can meet this standard only “if it is highly likely that the petitioner would prevail with respect to at least one challenged claim.” OpenSky Indus., LLC v. VLSI Tech.

“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

“the compelling merits standard, not the “reasonable likelihood” standard of § 314(a). We agree with Patent Owner that Petitioner does not show that Mahajan discloses or renders obvious the converted commands limitations of the claims. Particularly, all of the claims require that a media receiver (or computing device) receives a set of commands that is recognizable by the first type of media application and is converted via an API adapter to be recognizable by the first type of media playing application. Petitioner’s reliance on Mahajan’s Figure 3 for disclosing this limitation is not persuasive. Pet. 12–13, 39–41; Ex. 1102 ¶¶ 178–179, 182. Mahajan’s Figure 3, with Patent Owner’s annotations added coloring for different platforms and different commands, is reproduced below. Prelim. Resp. 28. Mahajan’s Figure 3, reproduced above with Patent Owner’s added coloring, shows that user-commands 306A–I (red) for server 202’s media platform are genericized by server 202’s RTS media abstraction module 210 (orange) using RTS mapping table 302 and corresponding generic commands 308A–I, 310A–I (grey) are sent to client 204’s RTS media abstraction module 214 (blue), which then converts the generic commands into platform-specific media commands 312A–I (green) for the client 204’s media platform. Ex. 1114 ¶¶ 35–43. More particularly, Mahajan discloses that its “RTS abstraction module 210 can translate the intercepted platform specific media commands into generic or abstracted media commands.” Ex. 1114 ¶ 36 (emphasis added). Next, “[t]he generic media commands can be sent from the server [202]’s RTS media abstraction module 210 to the client [204]’s RTS media abstraction module 214.” Id. Then, “[t]he client [204]’s RTS media abstraction module 214 can translate the generic media commands . . . into media commands that are specific to the client [204]’s media platform 212.” Id. Mahajan also discloses that “server [202]’s RTS media abstraction module 210 can receive media commands that are specific to the server [210]’s media platform 208.” Id. ¶ 37 (emphasis added). Thus, only media commands 312A–I (green) are specific to client 204’s media platform 212, not commands 306A–I, nor commands 308A–I, nor commands 310A–I. See id. ¶¶ 39–41. It appears that Petitioner recognizes such by stating that “Mahajan’s server translates specific commands of a first type to genericized commands, the genericized commands are transmitted, and then Mahajan’s client translates those generic commands to specialized commands of a second type.” Pet. 12–13 (citing Ex.1114 ¶¶ 35–36, Figs. 1–2) (emphasis added); see also Prelim. Resp. 30 (citing Pet. 34–35, 59, arguing Petitioner concedes Mahajan’s RTS Media Abstraction module of the client converts the commands received by the client from the server). With these disclosures, we agree with Patent Owner that any conversion of generic commands into platform-specific media commands for Mahajan’s client 204’s media platform 212 (as colorized green in Figure 3 by Patent Owner) is performed on the client 204 side, not on the server 202 side and thus, “Mahajan does not disclose the claimed component receiving a set of converted commands—i.e., commands that have already been converted when they are received.” Prelim. Resp. 27–28. We further agree with Patent Owner’s assessment that “Mahajan teaches that the client receives the generic commands alleged to be in a universal format; it does not disclose commands that are receive[d] in a first format that corresponds to [or is recognizable by] the first type of media playing application, as the claims recite.” Id. at 28; see Pet. 29–31, 39, 41; Ex. 1114 ¶¶ 36, 63. Petitioner appears to agree by stating that in regard to Mahajan’s teachings, 1) commands for a type of media playing application on the server are received at Mahajan’s server, 2) the commands are translated into a universal command, 3) the universal command is transmitted to the client, 4) the client re-translates the universal command, and 5) the new specific command is executed. Pet. 31 (citing Ex. 1114 ¶¶ 35–36, Figs. 1, 2; Ex. 1102 ¶ 159); see also Prelim. Resp. 29 (citing Ex. 1114 ¶¶ 13–14, 63).” slip op. at 20

“Petitioner does not explain how Redford’s Authority Server 282 of Figure 2B or Redford’s computer system 250 of Figure 3A converts the command so that the command is received by Redford’s set-top or internetenabled television 303 of Figure 3A, or how it would have been obvious to one of ordinary skill in the art to modify Redford’s system to have done so. In short, we have reviewed Petitioner’s contentions that Redford’s VideoPlay is a command that is converted at computer system 250 and that the VideoPlay command is sent to and received by television 303, but do not find such contentions supported by the cited disclosure of Redford.

Much of Petitioner’s contentions and Mr. Lett’s testimony rely on Redford’s disclosure of its settop API (Ex. 1005, 40:56–58), but neither Petitioner nor Mr. Lett provides sufficient evidence to show that Redford’s API converts the command at computer system 250 or at server authority 282 such that a converted command is received by television 303, as the claims require.
