    “provide sufficiently persuasive evidence in support of its position that claim 1’s “decoders” has a meaning broad enough to correspond to Zha’s decision rule. Petitioner disputes Patent Owner’s understanding of claim 1’s “decoders” by arguing that “[Patent Owner] does not argue that the specification disclaims decoders that do not perform error correction, or otherwise expressly limits the claimed bank of decoders to error correction.” Prelim. Reply 6. In support of its position, Petitioner cites Dr. Min’s testimony that “[i]n my opinion, a [person of ordinary skill in the art] would have understood that the ‘decision rule’ would be implemented using a decoder, as decoders typically make bit decisions.” Ex. 1003 ¶ 178; Pet. 59. Dr. Min does not cite any objective evidence in support of this view. Ex. 1003 ¶ 178. In response, Patent Owner marshals intrinsic evidence, along with Dr. Caire’s testimony based on objective supporting evidence. Prelim. Resp. 47–48; Prelim. Sur-Reply 5–6. For example, arguing that all embodiments disclosed in the ’703 patent use error-correcting coding, Patent Owner emphasizes the ’703 patent’s statement that “the [’703 patent’s] specification states that ‘[t]he invention is based on an iterative decoding solution that exploits error correction codes.’” Prelim. Sur-Reply 6 (quoting Ex. 1001, 25:27–29 (emphasis added by Patent Owner)). Patent Owner also cites the Abstract of the ’703 patent, which states that “[t]he present invention provides Turbo-decoding for joint signal demodulation based on an iterative decoding solution that exploits error correction codes.” Ex. 1001, code (57); Prelim. Sur-Reply 6. Patent Owner also cites Dr. Caire’s testimony that “any reasonable understanding of a decoder is one that implements an error correction coding approach.” Ex. 2001 ¶ 98; Prelim. Resp. 47. Dr. Caire cite objective evidence that supports this view. Ex. 2001 ¶ 98 (citing Ex. 2003, 3; Ex. 2004, 11; Ex. 2005, 228). Weighing the parties’ arguments and evidence, we find Patent Owner’s more persuasive than Petitioner’s. Starting with the intrinsic evidence, Patent Owner’s citation of the ’703 patent’s repeated statements that the “invention . . . exploits error correction codes” is more persuasive than Petitioner’s argument that the ’703 patent does not disclaim other approaches. Prelim. Sur-Reply 6 (citing Ex. 1001, 25:27–29, code (57)); Prelim. Reply 6. Petitioner argues that certain background documents suggest decoders may have a broad meaning, but this attorney argument warrants less weight than Dr. Caire’s testimony. Prelim.

When questioning who exactly had rights to which specific inventions of Mr. McElwain’s, Petitioner glosses over the key, undisputed fact that Mr. McElwain assigned the invention of the ’703 patent to the exact same entity to which Brommer was assigned, specifically BAESI. Ex. 2012, 2; Ex. 2011, 2. Mr. McElwain did so shortly after BAE filed Mr. McElwain’s provisional application on April 14, 2003, which both parties treat as the ’703 patent’s date of invention.

This, in combination with Patent Owner’s evidence regarding Mr. McElwain’s EPIIA and BAE’s acquisition of Lockheed Martin’s Aerospace Electronics System Business, evinces that Mr. McElwain had an obligation on April 14, 2003, to assign the invention of the ’703 patent to BAESI. Exs. 2014–2016. As Patent Owner notes, Petitioner does not advance a reason that Mr. McElwain would not have been obligated on April 14, 2003, to assign the invention of the ’703 patent to BAESI, much less provide evidence that he was not so obligated. See generally Prelim. Reply; Prelim. Sur-Reply 2. In sum, weighing the parties’ arguments and evidence, we do not find that Petitioner has a reasonable likelihood of prevailing on its position that Brommer is prior art to the ’703 patent for purposes of obviousness.

Nonetheless, Petitioner explains that the Petition is structured such that “Ground 1 is based on Patent Owner’s infringement contentions in the district court litigation, where the claimed ‘MUD module’ is generally mapped to multiple-input multiple-output (MIMO) receivers in a wireless network.” Pet. 2. Petitioner contends that “[u]nder this broad interpretation of a ‘MUD module,’ Walton’s MIMO receiver renders every challenged claim obvious.” Id. In contrast to Ground 1, the Petition states that “Ground 2 is based on the plain meaning of ‘MUD module,’ which is a component that detects, separates, and decodes signals from multiple users transmitting simultaneously over the same frequency band.” Id. Petitioner contends that, “[a]pplying the correct meaning of the term, Walton’s MIMO receiver does not necessarily comprise a MUD module.” Id. Therefore, Petitioner explains that “Ground 2 combines Walton with Learned, which expressly discloses [a] multi-user detector, and thus renders every challenged claim obvious in combination with Walton.” Id. at 2–3.7 In other words, the Petition presents Ground 1 and Grounds 2/3 as alternatives depending on the meaning of 7 Although not specifically relevant to claim construction, Petitioner explains that “Ground 3 further combines Walton and Learned with Quigley, to the extent Patent Owner argues Walton does not disclose providing a burst control input.” Pet. 3. “MUD module,” where Ground 1 is based on Petitioner’s understanding of Patent Owner’s interpretation of the term and Grounds 2 and 3 are based on Petitioner’s interpretation of the term as having its plain meaning. Petitioner further contends that “[e]very other claim term carries its ‘ordinary and customary meaning’ . . . .” Id. at 8. Although Petitioner presents a potential dispute regarding the meaning of “MUD module,” we need not construe this term expressly because the determination we reach herein does not depend on which meaning MUD module is applied.

    “We find the Petition lacking in particularity because it does not clearly identify what aspect of Jin is alleged to teach the unique signal parameters (or unique estimated signal parameters) recited in claim 1. See, e.g., 35 U.S.C. § 312(a)(3) (“A petition filed under section 311 may be considered only if — (3) the petition identifies, in writing and with particularity, . . . the evidence that supports the ground for the challenge to each claim . . . .”). First, as reflected above, the Petition asserts that something called a “unique pilot parameter” teaches the recited unique estimated signal parameters. But “unique pilot parameter” is not a term or phrase recited in Jin. See Prelim. Resp. 19 (arguing the same). So, when Petitioner states “Jin discloses that the base station uses the unique pilot parameter (i.e., ‘unique estimated signal parameters’) to ‘identify which user (i.e., mobile terminal) has transmitted the received data,’” it is not clear what element in Jin Petitioner intends to identify by the term “unique pilot parameter.” Dr. Min’s testimony does not help resolve the ambiguity in the Petition. In particular, Dr. Min also refers to a “unique pilot parameter (i.e., ‘unique signal parameter’) for each user.” Ex. 1003 ¶ 89.

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for patent owner

    “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

Apart from arguing that the recited “parameter estimation unit” is limiting, Petitioner does not propose any id. Patent Owner does not respond to Petitioner’s contentions and also does not argue that any construction is necessary for the parameter estimation unit. See generally Prelim. Resp. As reproduced in Section II.D. above, the preamble of claim 1, in its entirety, recites, “In a multi-user detection system in which interfering signals are purposely allowed to exist, a parameter estimation unit for use in conjunction with a signal separation unit, in which each received signal has associated channel transfer functions.” Ex. 1001, 12:41–45.

Id. at 14:3–7 (reciting “In a multi-user detection system in which interfering signals are purposely allowed to exist, a parameter estimation unit for use in conjunction with a signal separation unit for estimating channel transfer function parameters from channel transfer functions”). The body of each claim recites the elements of the recited “parameter estimation unit,” namely, “a signal processor for determining said channel transfer functions for each received signal” and “means . . . for providing uninterrupted estimates of the channel transfer function parameters on a real-time basis . . . .” The phrase “In a multi-user detection system in which interfering signals are purposely allowed to exist” provides additional context for the environment in which the parameter estimation unit is intended to operate. Whether the preamble is limiting is a question that we do not need to decide here, however. Only those claim terms that are in controversy need to be construed, and only to the extent necessary to resolve the controversy. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.

Under that second step, “structure disclosed in the specification is corresponding 6 Section 4(c) of the Leahy-Smith America Invents Act (AIA) re-designated 35 U.S.C. § 112 ¶ 6, as 35 U.S.C. § 112(f). Because the ’676 patent has a filing date before September 16, 2012 (effective date of the statute), we refer to the pre-AIA version of 35 U.S.C. § 112. associates that structure to the function recited in the claim.” Med. Instrumentation & Diagnostics Corp. v. Elekta AB, 344 F.3d 1205, 1210 (Fed. Cir. 2003). Our Rules specifically require that the petition identify the corresponding structure in proposing a construction for a means-plus-function claim limitation. 37 C.F.R. § 42.104(b)(3). “This inquiry is undertaken from the perspective of a person of ordinary skill in the art.” Cardiac Pacemakers, 296 F.3d at 1113.” slip op. at 19

Where a Petition presents a reasonable likelihood of success as to only a small number of the challenged claims, the Board has the discretion to decline to institute review, because instituting a full review on all challenged claims may be an inefficient use of the Board’s limited resources. See, e.g., Deeper, UAB v.

Of the eighteen challenged claims, we have found that Petitioner failed to establish a reasonable likelihood of success as to sixteen of those claims. This leaves a single independent claim (claim 17) and a single dependent claim (claim 18) remaining for consideration. Even were we to conclude that Petitioner had established a reasonable likelihood of success as to claims 17 and 18, this would leave at most two claims subject to a single ground upon which such a showing had been made, out of eighteen challenged claims. Based on the particular circumstances of this case, it would be inefficient for the Board to expend resources on a full review of all eighteen challenged claims, where Petitioner has failed to establish even a reasonable likelihood of success as to the vast majority of those claims. Accordingly, we need not, and do not, take any position as to Petitioner’s showing on Ground 2 but instead exercise our discretion to deny review.” slip op. at 21

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation not foundNot shown unpatentable

    “the parties’ arguments, we understand Mitchell to teach the propagation of failure information from the location of the failure to the network’s edge or endpoints and that this propagation excludes nodes between the detected failure and the network’s core. Therefore, the question before us is whether one of ordinary skill in the art would have learned of the recited propagation and receipt to and from “each node of the other nodes of the plurality of network nodes traversed by the first set of links”8 from Mitchell’s downstream propagation of failure information. We are not persuaded that Petitioner’s showing is sufficient. Petitioner relies upon a circumstance where the failure occurs far upstream and uses that case to assert that Mitchell teaches the recited propagation and receipt. Claims 1 and 16, however, respectively recite the propagation to “each node” and “all nodes.” Mitchell, in contrast, does not teach propagation to each node, but rather it teaches continuing down the path to message only the remaining nodes in the path between the failure and the endpoints. It specifically and explicitly sets out to maintain connectivity with all nodes upstream of the failure. This is materially different from the claims of the ’637 patent, and Petitioner has not provided a sufficient explanation to establish that one of ordinary skill in the art would have found it obvious to extend Mitchell’s downstream-only propagation to instead” slip op. at 19

    “and 16. See Prelim. Resp. 7–10. For example, claim 1 additionally recites, in relevant part, “deactivating a physical layer of the first set of links connected thereto, thereby causing a loss of connectivity in the first set of links.” Ex. 1001, 11:37–39 (limitation [1h]). Claim 16 similarly recites, in relevant part, “to deactivate the physical layer resources of each node to links in the first set of links connected to that node upon receiving the second message, to cause a loss of connectivity in the first set of links.” Id. at 12:54–58 (limitation [16g]). Thus, claims 1 and 16 both require deactivating the physical layer of nodes in order to cause a loss of connectivity in the first set of links. Petitioner asserts that Mitchell teaches that “the physical layer of the links connected downstream of these network elements are deactivated, which causes a loss of connectivity in the ‘group of links.’” Pet. 26 (emphasis omitted); see also id. at 36 (making same argument for claim 16). We are not persuaded that downstream deactivation teaches the deactivation of “each node” nor does it teach the “loss of connectivity in the first set of links.” This is true because Mitchell teaches the preservation of connectivity in upstream links. Petitioner does not argue that one of ordinary skill would have understood Mitchell to teach deactivation of the set of links, but rather Petitioner argues that there could be a circumstance where Mitchell may be unable to preserve connectivity because the failure happened at the most upstream location. This is not sufficient to teach a system that deactivates all nodes in the set of links in order to cause a loss of connectivity in the set of links because Mitchell sets out to maintain some degree of connectivity. We agree with Patent Owner that the disclosures of Mitchell would not have taught one of ordinary skill in the art the recited propagation and receipt of failure information to and by each of the nodes in the network nor would it have taught the recited deactivation to cause a loss of connectivity in the set of links. As such, Petitioner has not met its burden to demonstrate that Mitchell would have rendered independent claims 1 or 16 obvious. As to dependent claims 2–15 and 17–25, Petitioner makes no further allegations that would remedy the deficiency discussed above in regards to the independent claims. As such, Petitioner has not met its burden to show that any of claims 1–25 would have been obvious over the asserted art.” slip op. at 20
