    “B. Level of Ordinary Skill in the Art As noted above, resolving the question of obviousness requires determination of the level of ordinary skill in the art. Graham, 383 U.S. at 17–18. Here, however, as Patent Owner observes (Prelim. Resp. 10), 8 Patent Owner does not present arguments or evidence of secondary considerations in its Preliminary Response. Therefore, secondary considerations do not constitute part of our analysis herein. Petitioner has provided no assessment as to the level of ordinary skill to be considered in evaluating the grounds of obviousness that are advanced by Petitioner. The absence of such assessment calls into question the fundamental adequacy of Petitioner in carrying its burden to show a reasonable likelihood of success of unpatentability of the challenged claims that necessarily must take into account the level of ordinary skill in the art.” slip op. at 10

    “We agree with Patent Owner and find that Petitioner does not sufficiently explain why the skilled artisan, given Mahieux, would have had a rational reason to modify Mahieux to keep track of, let alone make use of, perceptibly significant frequency bands. Indeed, Patent Owner’s declarant, Dr. Kyriakakis, persuasively testifies why modifying Mahieux to do so would have made no sense to the skilled artisan: It would not have made sense to modify Mahieux’s system to instead count the number of audible frequency bands (e.g., the number of audible frequency bands B1-B3), as such a count would play no role in Mahieux’s bit allocation. Indeed, as Mahieux’s bit allocation focuses on the number of non-zero coefficients in each individual frequency band in isolation and without regard to the aggregate number of total audible frequency bands of the overall spectrum, generating an aggregate number of total audible frequency bands (e.g., by counting) serves no purpose in Mahieux’s allocation scheme. Further given Mahieux’s focus on allocating bits to frequency coefficients in individual frequency bands in isolation from other bands, [the skilled artisan] would fail to find any use for such an aggregate number or count. Ex. 2002 ¶ 92 (cited at Prelim. Resp. 23). Thus, we find Petitioner does not sufficiently explain why modifying Mahieux to keep track of perceptibly significant frequency bands would have presented itself to the skilled artisan as an option at all, let alone an option that would have been obvious to try.

    “There is, however, a consistent thread that flows through the relevant disclosures of the specification; namely, that the “state involving the SIP sequence” is maintained throughout a dialog. Ex. 1001, 5:1–38 (step 210); see also id. (step 160). Using the method of Figure 4, including steps 160 and 210 and maintaining the SIP signaling state, is how the ’554 Patent discloses that calls are not broken or dropped. See, e.g., id. at 7:10–25. Maintaining the “state” of the SIP signaling sequence includes (but is not limited to) the teachings that a “SIP signaling sequence number” is maintained, as well as the details of how that number is maintained, as set forth in the specification. We find that the state of the SIP signaling sequence as that term is used in the specification refers to the rules (or paradigm) used to identify a collection of SIP signals as a “SIP signaling sequence,” and in particular the rules used to identify the next SIP packet received as belonging to a sequence of packets previously received. One key to the disclosed invention discussed in the specification is the concept that the invention prevents a call 3:45–4:9. The specification contends that the invention accomplishes this goal by configuring the packets involved in a VoIP call such that the receiving device (e.g., a SIP server) is able to recognize those packets as belonging to the same call, even though the packets are received over different paths. Id. at 7:35–50; 7:60–8:3. The particular way that the receiving devices are able to recognize that the packets are part of the same call is, per the claims, because the SIP signaling sequence is maintained after a network switch. Id. at 8:27–29. Thus, where a sequence of SIP signals uses numbers such as cseq values, there is a rule for identifying what the next signal in the sequence is. Ex. 1001, 5:1–38. A receiving device that knows the rule can identify an incoming packet as the next packet in the same signaling sequence as previously received packets, by applying the rule. Id. at 7:35–50. The specification provides one example rule, that the next SIP signal bears a monotonically-increasing cseq number. Id. at 5:1–38. But there could be other such rules as well. For example, the value could be monotonically decreased, or the value could be determined using some other formula.8 The claims also do not require that the sequence of SIP signals use “numbers” as sequence identifiers.9 Other labeling paradigms could be possible as well, 8 Patent Owner’s litigation claim construction improperly imports implementation details from the preferred embodiment, such as “cseq numbers” and the limitations that these numbers “monotonically increase” for new transmissions, or be “preserved” for re-transmissions. While such embodiments would be one way of maintaining a SIP signaling sequence, the specification does not clearly limit the invention to only these embodiments. 9 Petitioner’s litigation claim construction improperly imports the limitation from the preferred embodiment that the SIP signaling sequence must be” slip op. at 14

    “as of the time of the invention of the ’554 Patent “would have been familiar with designing rules for implementing policies for service plans for use of an access network and provisioning those rules to network elements for policy enforcement” and would have gained this knowledge through a mixture of training and work experience, such as by having a Bachelor’s degree in electrical engineering or computer science and two years of experience; or by obtaining a Master’s degree in electrical engineering or computer science, but having only one year of experience; or by having no formal education but experience in network service plan provisioning systems of at least four years.

    “We disagree with Petitioner’s view of Tagg. At best, the cited portions of Tagg disclose that SIP is used by endpoint 1512 to communicate with SIP server 1500, and by the SIP server to communicate with SIP proxy 1504. Figure 15 discloses that SIP is used for both of the paths from endpoint 1520 to SIP server 1500, via the WWAN or the WLAN. Figure 15 further discloses that SIP is used for the path from SIP server 1500 to SIP proxy 1504. But Figure 15 and the accompanying text are silent about any “sequences” of SIP signals at all, much less whether any such “sequences” are maintained, as required by the language of limitation 1.6. Ex. 1005 ¶¶ 324–346, Fig. 15. Instead, Tagg’s specification simply discloses that SIP is used to perform call management functions. Id. ¶¶ 245–247. Tagg’s cases 1 and 6, relied on by Petitioner, teach that Tagg’s server can ensure that the end user appears to the rest of the world (i.e. the devices upstream of the SIP server) as if no network change is being made. Ex. 1005 ¶ 320. Tagg further teaches that either “make before break” or “make and break” schemes may be used. Id. But these cases do not explain how any SIP signaling sequences are used, much less how or even that any SIP signaling sequence is maintained when a network switches. At most, Tagg teaches that each path will have an IP (Internet Protocol) address, which may be the same or different for each path. Id. ¶ 288. But IP addresses are part of the IP disclosing or suggesting that IP addressing schemes are maintained or otherwise accounted for in a network switch, that would not be sufficient to disclose or suggest that SIP signal sequences are maintained. Furthermore, under our construction of limitation 1.6, it must be shown that the same rules or paradigm used to identify that an incoming SIP packet is the next SIP packet in a sequence, regardless of whether that packet is transmitted on the first network path or the one of a plurality of alternative network paths. The Petition is silent on this point. The closest Petitioner comes is the assertion that Figure 15 depicts preservation of “the same SIP signaling sequence,” with the Petitioner’s explanation being that Tagg allows simultaneous connections across a WWAN and a WLAN, and that “POSITAs would have understood that Tagg’s SIP protocol uniformity in directionality teaches that a ‘SIP signaling sequence . . . is maintained.’” Pet. 39–40.” slip op. at 22

    “B. Level of Ordinary Skill in the Art Petitioner asserts that “a person having ordinary skill in the art (‘POSITA’) at the relevant time, would have had at least a bachelor’s degree in electrical engineering, or equivalent experience of at least two years working in the field of the design electrical driver systems for Light Emitting Diodes (LEDs).” Pet. 20. Patent Owner has not addressed the level of ordinary skill in the art. See generally Prelim. Resp. For purposes of this Decision, we adopt Petitioner’s proposed level of ordinary skill, as articulated above. We determine this level of skill comports with the qualifications a person would have needed to understand and implement the teachings of the ʼ432 Patent and the prior art of record. Cf. Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (noting that the prior art itself may reflect an appropriate level of skill in the art).

    “First, even under Petitioner’s assertion that “controller RG . . . performs the functions of an error amplifier and amplifier output stage” (id. at 37), Petitioner has not adequately shown that controller RG meets all three of “an error amplifier,” “a control voltage,” and “an amplifier output stage.” Petitioner’s assertions that those elements are “interior to” or “include[d]” in controller RG are conclusory and unsupported. Petitioner summarizes and reproduces portions of Sudhaus regarding the output currents of controller RG, but has not explained the relevance of its summary and reproduction with respect to each recited claim element. See id. at 37–38 (citing Ex. 1005, 2:32–33, 4:25–28, 4:46–50, 8:47–55), 40– 41. Nor has Petitioner explained why or how the summarized or reproduced portions of Sudhaus show that those claim elements are interior or included in controller RG. See id. Further, Petitioner also fails to show how Sudhaus teaches the claimed interactions and relations between the error amplifier, control voltage, and amplifier output stage. The claim recites the error amplifier compares voltages to “generate a control voltage” and the amplifier output stage controls output current “based on the control voltage.” Petitioner has not explained what specific signal controller RG generates that teaches a “control voltage” used to control output current. Nor has Petitioner stated, let alone explained how, controller RG generates a control voltage in the claimed manner and controls output current based on that control voltage. Simply because controller RG produces outputs that are allegedly similar to the claimed outputs does not by itself show that controller RG produces the claimed outputs using the claimed elements in the claimed manner.” slip op. at 16
