    “We also agree with Patent Owner that the charge cut-off voltage is not necessarily the applied voltage during charging. PO Resp. 20. Rather, depending on the charging protocol used and when in the charging cycle the voltage is applied, the applied voltage could be higher than the battery voltage. Ex. 2013; Ex. 2006 ¶ 91. For example, as discussed in more detail below with respect to the Uemura grounds, when fast charging using constant current is used and the charging rate is not slow, the applied voltage will be higher than the battery voltage when the constant current charging phase is stopped. Ex. 2006 ¶ 91; Ex. 2013. Likewise, during constant current/constant voltage charging, the applied voltage approximates the battery voltage only when the battery is nearly completely charged. Ex. 2013; Ex. 2006 ¶ 91. Thus, the applied voltage may be, but is not necessarily, the charge cut-off voltage. In view of the foregoing, we construe “charge cut-off voltage” in claims 1 and 5 as “the maximum value to which the battery is configured to be charged.” PO Resp. 18; Ex. 2008, 217:6–11; Pet.

First, we agree with Petitioner that the ’641 patent indicates that the charge cut-off voltage selected for a particular battery need not be a fixed property of the battery or something that is set by the design and chemistry of the battery. Consistent with this conclusion, the ’641 patent discloses that a “charging device controls the charge cut-off voltage of the single lithium-ion cell within a range from 4.3 V to 5.8 V.” Ex. 1001, 9:50– 55. This strongly suggests that the charge cut-off voltage is controlled by the charger and is not necessarily an inherent property of the battery.

Dr. Bottoms provides a “clarification” of the Board’s description, testifying that “[t]he specific industry experience would require process design experience—which is experience beyond managing fabrication equipment.” Ex. 2011 ¶ 36.

    “copper interconnects need silicon nitride films as an etch stop, but that such films have a high dielectric constant, which causes an undesirable increase in the effective dielectric constant of the interconnect structure and increased parasitic capacitance, as compared with aluminum interconnects. Ex. 1021, 829-1, 829-2; see Pet. 18; Ex. 1011 ¶¶ 92, 93. As Petitioner correctly points out (Pet. 53–54), Tanaka (1999) cites Igarashi as an example of a copper interconnect system that is degraded by parasitic capacitance due to the high permittivity (dielectric constant) of silicon nitride etch stop films. Ex. 1017, 47-1 n.1. Tanaka (1999) discloses a low dielectric constant silicon nitride etch stop film as a solution to the problem of parasitic capacitance in copper damascene interconnect structures, such as Igarashi’s. Id. at 47-1, 47-2 (“New low-k SiN film, with a permittivity of 5.4 . . . should be the solution to realize Cu damascene interconnects . . . .”). Consistent with these express disclosures, Dr. Neikirk persuasively testifies that “Igarashi identifies a need for a low-k dielectric etch stop layer” and “Tanaka (1999) meets this need.” Ex. 1011 ¶ 94; see Pet. 18 (citing Ex. 1011, § VIII.C., which contains paragraph 94 of Dr. Neikirk’s testimony). Accordingly, we find Petitioner has shown by a preponderance of the evidence that a POSA would have been motivated to use the low dielectric constant silicon nitride etch stop film of Tanaka (1999) as the etch stop layer in the interconnect system of Igarashi. Patent Owner disputes whether Petitioner has established a reasonable expectation of success for the combination of Tanaka (1999)’s low dielectric constant silicon nitride etch stop film and Igarashi’s interconnect structure. PO Resp. 65. Although the Petition does not expressly discuss whether one of ordinary skill in the art would have had a reasonable expectation of success in combining Tanaka and Igarashi to arrive at the claimed invention, Petitioner shows a very close relationship between the teachings of Tanaka (1999) and Igarashi. Pet. 12–13, 17–18, 53–62. As discussed above and argued by Petitioner, Tanaka (1999): (1) cites Igarashi as an example of a copper interconnect system that suffers from parasitic capacitance due to the high dielectric constant of silicon nitride etch stop films, and (2) discloses a low dielectric constant silicon nitride etch stop film as a solution to the parasitic capacitance problem exemplified by Igarashi. Pet. 13, 18, 53–54; Ex. 1011 ¶¶ 74–79, 88–94; Ex. 1017, 47-1 & n.1; Ex. 1021, 829-1, 829-2. Petitioner establishes a reasonable expectation of success for the combination of Tanaka (1999) and Igarashi by demonstrating a strong correlation between the problem discussed by Igarashi—the high dielectric constant of silicon nitride films when used as etch stops for copper interconnects—and the solution disclosed by Tanaka (1999)—a low dielectric constant silicon nitride film for use as an etch stop layer in copper damascene interconnect structures.

See Graham, 383 U.S. at 17–18 (noting that “long felt but unsolved needs” and commercial success may be utilized as indicia of nonobviousness). Indeed, we have been directed to no persuasive evidence that a mixture of CO2 and a fluoroalkene of claim 1 has ever been used commercially, or that such a mixture was considered by those of ordinary skill in the art to have met a long felt but previously unresolved need.9, 10 See Tr. 51:24–52:7; Pet. Reply 9 (asserting that Patent Owner “has provided no evidence, post- or pre- issuance of the ’808 patent, of the commercial advantages or uses of the claimed compositions”). With respect to Petitioner’s prior patent applications, although Patent Owner initially characterizes these applications as relating to CO2 and partially fluorinated hydrocarbons, Patent Owner later notes that these patents are directed to blends of HFO-1234yf, CO2, and R-134a. PO Resp. 44; Ex. 2024, 12 (arguing in support of patentability that “[t]he specific 9 To be relevant, Patent Owner must show that the asserted secondary considerations are attributable to “the merits of the claimed invention beyond what was readily available in the prior art.” Asyst Techs. v. Emtrak, Inc., 544 F.3d 1310, 1316 (Fed. Cir. 2008). Here, Inagaki discloses using compounds within the scope of claim 1 of the ’808 patent as refrigerants. Patent Owner presents no persuasive evidence that the addition of CO2 to the compounds of Inagaki, or the particular ranges recited in claim 1, resulted in a product that met a long felt but unresolved need or resulted in a commercially successful product beyond what was provided in Inagaki. Thus, we are also not persuaded that there is any nexus between the asserted secondary considerations and the features of claim 1 that are not disclosed in Inagaki. 10 As Patent Owner has not demonstrated any commercial use of the claim 1 compounds for any purpose, or provided evidence that those of skill in the art considered the claimed compounds to have met an unresolved need in the art, this analysis applies equally to the dependent claims of the ’808 patent, which each depend, directly or indirectly, from claim 1. combination of trans-R1234ze and R134a and CO2 simply is not suggested in Singh, let alone in the amounts defined in claim 1”). Patent Owner does not explain sufficiently why Petitioner’s arguments directed to the patentability of a blend of three compounds, utilized in specific proportions, are necessarily applicable to the combination of Kruse, Inagaki, and Butler proposed by Petitioner, or why these arguments are otherwise strong evidence of the nonobviousness of claim 1 of the ’808 patent. Based on the foregoing, and upon review of Patent Owner’s arguments as a whole, we are not persuaded that Patent Owner’s proffered objective evidence of nonobviousness is strong or tends to refute Petitioner’s arguments and evidence with respect to the obviousness of claim 1 of the ’808 patent.” slip op. at 25

    “Patent Owner’s motion to exclude Exhibits 1013, 1014 and 1015 is denied. As Patent Owner points out, 37 C.F.R. § 42.6(a)(3) indicates that “[a]rguments must not be incorporated by reference from one document into another document.” We are not persuaded, however, that Petitioner is attempting to incorporate by reference; Exhibits 1013, 1014, and 1015 are cited by Petitioner’s declarant, not incorporated by reference. If Petitioner’s declarant or the cited exhibits contained arguments not made in a paper, we would likely ignore such arguments. In this instance, Petitioner is making of record the documents cited, which is generally laudatory, so that a reader can determine for herself that cited facts are supported. We are not persuaded that the cited exhibits are “irrelevant.” Additionally, we find no support for Patent Owner’s contention that exhibits must be cited by “papers,” and not other exhibits. Many exhibits, such as declarations, prior art references, and deposition transcripts, cite to other exhibits in normal trial practice.

Petitioner also has the initial burden of production. Id.

    “production under § 103(c)(1), Petitioner contends it carried its burden of production to show that the ’167 patent (grandparent) sufficiently would have conveyed to one of ordinary skill in the art that the Patent Owner had possession of the claimed subject matter and, therefore, the ’260 patent is entitled to the benefit of the filing date of the ’167 patent. Reply 7. As Petitioner recognizes (Reply 6), a claim in an application is entitled, under 35 U.S.C. § 120, to the benefit of the filing date of an earlier filed application only if the disclosure of the earlier application provides support for the claims in the later application, as required by 35 U.S.C. § 112. 35 U.S.C. § 120; In re Chu, 66 F.3d 292 (Fed. Cir. 1995). Petitioner’s argument consists of a single paragraph identifying claim numbers and locations where the ’167 patent purportedly describes the subject matter of most, but not all, of the claims at issue and a citation to a single paragraph in its declarant’s supplemental declaration supporting Petitioner’s Reply.

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

    “The ’260 patent does not set forth a special definition for “call application management system.” As confirmed by Dr. Forys (id.), the plain language of the claim specifies the function required to be performed by the call application management system—connecting calls responsive to 26 receiving a request to connect the call. Although Dr. Forys found Patent Owner’s proposed construction to be “reasonable,” Patent Owner’s proposed construction unnecessarily introduces the term “call processing,” which is not recited by the claim itself and on its face seems broader than the recited function of a call application management system—to connect a call. We do not agree with Patent Owner that a call application management system must perform examples of call processing described by the Specification, but not recited in the claim. Limitations from embodiments are not to be imported into the claims. See In re Van Geuns, 988 F.2d at 1184. Furthermore, we find that Patent Owner’s contention— the name “the call application management system would be understood [by one of ordinary skill in the art] to manage, from start to finish, each call placed or received at the plurality of prisons” (PO Resp. 6)—places too much weight on the term “management” without sufficiently addressing the term “application.” We credit the testimony of Petitioner’s declarant, who disagrees that call application management system is required to manage “all call processing, ‘from start to finish.’” Ex. 1020 ¶ 8. Therefore, in light of the plain language of the claim, the Specification of the ’260 patent, and according the testimony of Patent Owner’s declarant and Petitioner’s declarant appropriate weight, we construe “call application management system” to mean a system that performs the enumerated function—“connecting a call to or from the telephone terminals over a telephone carrier network responsive to receiving a request for connecting the call.”” slip op. at 26

    “endorsement.” In proffering constructions, neither party provides sufficient evidence of the ordinary meaning of “bi-lateral” or “endorsement.” We determine the ordinary meaning of the terms “bi-,”7 “lateral,”8 and “endorsement”9 collectively mean “both sides giving approval.” The use of “bi-lateral endorsement” in independent claims 7 and 23 indicate that an endorsement occurs between two parties, a subscriber and an advertiser, which is consistent with its ordinary meaning of “both sides giving 7 AMERICAN HERITAGE DICTIONARY 181 (3d ed. 1992) (defining “bi-” as “1. a. Two . . . b. Both . . . c. Both sides, parts, or directions”). 8 AMERICAN HERITAGE DICTIONARY 1017 (3d ed. 1992) (defining “lateral” as “1.

Ex. 1001, col. 7, ll. 56-58. As part of an enrollment process, the advertiser decides whether to endorse a particular subscriber. Id. at col. 8, ll. 47-48. The bi-lateral endorsement is completed after the subscriber chooses at least one plan and one advertiser for endorsement. Id. at col. 8, l. 66 – col. 9, l. 3. The ’679 patent also describes examples of endorsement by an advertiser of a subscriber and endorsement by a subscriber of one or more advertisers. See id. at col. 3, ll. 39-65, col. 4, ll. 59-65.

    “We agree. In general, a preamble is construed as a limitation “if it recites essential structure or steps, or if it is ‘necessary to give life, meaning, and vitality’ to the claim.” Catalina Mktg. Int’l, Inc. v. Coolsavings.com, Inc., 289 F.3d 801, 808 (Fed. Cir. 2002) (quoting Pitney Bowes, Inc. v. Hewlett-Packard Co., 182 F.3d 1298, 1305 (Fed. Cir. 1999)). When the limitations in the body of the claim “rely upon and derive antecedent basis from the preamble, then the preamble may act as a necessary component of the claimed invention.” Eaton Corp. v. Rockwell Int'l Corp., 323 F.3d 1332, 1339 (Fed. Cir. 2003). Notably, the preamble of independent claim 7 requires “a source communication device possessed by a subscriber,” “a destination communication device possessed by a recipient,” and “an advertisement.” The body of claim 7 recites “the source communication device,” “the subscriber,” “the destination communication device,” and “the 18 advertisement,” all of which rely on and derive antecedent basis from the preamble of claim 7. Similarly, the preamble of independent claim 23 recites “a first communication device,” “a second communication device,” and “a set of advertisers.” The body of claim 23 recites “the first communication device,” “the second communication device,” and “the set of advertisers.” Accordingly, we conclude that the preambles of independent claims 7 and 23 are entitled to patentable weight.” slip op. at 18

    “Based on the above disclosures of Paul, we find that the direct e-mail campaign and a “refer-a-friend” campaign are not different methods, but are different tool options provided by the campaign manager computer program in the e-mail communications system disclosed by Paul. Accordingly, as different tool options of the campaign manager in the e-mail communications system, one of ordinary skill in the art would understand that the direct e-mail campaign tool option was to be used in conjunction with the “refer-a-friend” campaign tool option to send “refer-a-friend” e-mail message incentives to a subset of the members based on member demographic characteristics. To determine otherwise would require a finding that one of ordinary skill in the art, when reading Paul, would come to the conclusion that the only option would be to send a “refer-a-friend” e-mail to all members. We do not find that one of ordinary skill in the art would have understood Paul to be so restrictive. Rather, Paul’s disclosure of the campaign manager computer program having multiple tool options to develop marketing campaigns is analogous to a reference disclosing two functions of a word processing program—creating a document and saving a document.
