NAPPI, BETH Z. SHAW, and JAMES W. DEJMEK, Administrative Patent Judges. DEJMEK, Administrative Patent Judge. DECISION ON APPEAL Appellants appeal under 35 U.S.C. § 134(a) from a Final Rejection of claims 37-39 and 41-56. Appellants have canceled claims 1-36 and 40. App. Br. 22. We have jurisdiction over the remaining pending claims under 35 U.S.C. § 6(b ). We affirm-in-part. 1 Appellants identify Alcatel Lucent as the real party in interest. App. Br. 1. Appeal2018-001513 Application 11/556,730 STATEMENT OF THE CASE Introduction Appellants' disclosed and claimed invention generally relates to updating the configuration of a mobile communication network with respect to Tracking Areas (i.e., a location area or routing area used to keep track of a mobile device's location). Spec. 1: 11-12, 2:6-12, 3:30-32, 4: 15-17. In a disclosed embodiment, an ENB (enhanced Node B) sends (for example, at start-up or periodically) a Tracking Area registration message, or registration request, to a Paging Coordination Entity (PCE) managing the Tracking Area. Spec. 10:6-13. According to the Specification, the PCE accepts or rejects the request and, if accepted, "the PCE adds (and/or possibly removes, depending on information within the registration message) the ENB address ... associated with the Tracking Area(s)." Spec. 10:14--18; see also Fig. 3. Claims 37 and 43 are exemplary of the subject matter on appeal and is reproduced below with the disputed limitations emphasized in italics: 37. A method for configuring a cellular mobile communication network with Tracking Areas, comprising: sending, from an Enhanced Node B (ENB), a request message to a Mobility Management Entity (MME), the request message including at least one Tracking Area supported by the ENB, in order to indicate to the MME that the ENB is to be associated with the at least one Tracking Area; and receiving, at the ENB from the MME, one of a [sic] accept message and a reject message indicating that the request message is one of accepted and rejected, the ENB having both the capability of receiving an accept message and the capability of receiving a reject message. 2 Appeal2018-001513 Application 11/556,730 43. A Mobility Management Entity (MME) of a mobile communication network, configured to: receive a request message from an Enhanced Node B (ENB), the request message including at least one Tracking Area supported by the ENB, in order to indicate to the MME that the ENB is to be associated with the at least one Tracking Area; said MME further configured to send an accept message or a reject message to said ENB; said MME further having both the capability of accepting said request and the capability of rejecting said request. The Examiner's Rejections 1. Claims 37, 38, 41--46, and 49-56 stand rejected under 35 U.S.C. § I03(a) as being unpatentable over Motegi et al. (US 2003/0109254 Al; June 12, 2003) ("Motegi") and Applicants' Admitted Prior Art ("AAPA"). Final Act. 3-9. 2. Claim 39 stands rejected under 35 U.S.C. § I03(a) as being unpatentable over Motegi, AAPA, and De Sousa (US 2008/0298275 Al; Dec. 4, 2008 (PCT filing date: June 3, 2005)). Final Act. 9-10 3. Claims 47 and 48 stand rejected under 35 U.S.C. § I03(a) as being unpatentable over Motegi, AAP A, and the Examiner's taking of Official Notice. Final Act. 10-11. 3 Appeal2018-001513 Application 11/556,730 ANALYSIS 2 Claims 37-39, 41, 42, 47, 48, 50, and 51 In rejecting, inter alia, independent claim 37, the Examiner finds Motegi teaches or suggests most of the recited limitations, but does not expressly teach that its disclosed base station is an enhanced Node B (ENB) and that the ENB is to be associated with at least one Tracking Area. Final Act. 3-5. We begin our analysis with a brief review of Motegi. Motegi is generally directed to location registration area configuration in a mobile communication network. See Motegi ,r,r 2, 9 ("a location registration area configuring method"). Motegi describes an exemplary network comprising a plurality of mobile stations, a plurality of base stations connected to a network, and a location information management server. Motegi ,r 9, Fig. 1. Motegi further describes the location information management server as "configured to manage location registration areas formed of cells established by the base stations and location information about locations of the mobile stations." Motegi ,r 9. Further, as base stations are added or removed from the network in Motegi, the location information management server updates a location registration area management table accordingly. Motegi ,r 61. 2 Throughout this Decision, we have considered the Appeal Brief, filed August 31, 2017 ("App. Br."); the Reply Brief, filed November 27, 2017 ("Reply Br."); the Examiner's Answer, mailed November 2, 2017 ("Ans."); and the Final Office Action, mailed April 12, 2017 ("Final Act."), from which this Appeal is taken. 4 Appeal2018-001513 Application 11/556,730 Figure 5 of Motegi is illustrative and is reproduced below: Fig .. 5 (s1~\RT.) -x--............... ..

Motegi ,r 4 7; see also Motegi ,r 71. Motegi teaches if the location information management server determines that the "notification" received from the base station is for removal (S51 ), the base station and its accompanying information is deleted from the location registration area management table (S52). Motegi ,r 71. If the location information management server determines that the "notification" received from the base station relates to a new installation of a base station (S53), the location information management server registers information about the 5 Appeal2018-001513 Application 11/556,730 newly installed base station in the location registration area management table (S54). Motegi ,r 71. Additionally, the location information management server will notify the base station that it has been registered (S56). Motegi ,r 71. Appellants argue the Examiner erred in finding the location information management server in Motegi teaches or suggests the claimed Mobility Management Entity (MME). App. Br. 9-12. In particular, Appellants assert that Motegi' s system ( which Appellants argue if further described in a patent identified in the Background section of Motegi) 3 relates to, and incorporates network elements used in previous generation networks and that "it is well-known in the industry that a 'Mobility Management Entity (MME)' (recited in claim 37) is different from a central database ( conventionally called a Home Location Register, or HLR), or Home Subscriber Server (HSS), where the MME is known to not be a part of the HLR and/or HSS." App. Br. 10. As an initial matter, it is well settled that mere attorney arguments and conclusory statements, which are unsupported by factual evidence, are entitled to little probative value. In re Geisler, 116 F.3d 1465, 1470 (Fed. Cir. 1997); see also In re Pearson, 494 F.2d 1399, 1405 (CCPA 1974) ( attorney argument is not evidence). Appellants do not provide persuasive evidentiary support for their assertion. Contrary to Appellants' arguments, the Examiner finds, and we agree, Motegi' s location information management server teaches the claimed MME. See Final Act. 4; Ans. 9-10. The Examiner's finding is consistent with Appellants' Specification, in which "the network entity in charge of MM [(Mobility Management)] 3 Onoe et al. (US 5,361,396; Nov. 1, 1994). 6 Appeal2018-001513 Application 11/556,730 function is called Mobility Management Entity (MME) ... regardless of the physical network node(s) where these functions can be located." Spec. 3:22-26. As described above, Motegi's location information management server is performing Mobility Management functions by, at least, managing location information of the mobile stations. Cf Spec. 2:6- 12 (Mobility Management functions include "keeping track of MS/UE [(mobile stations/user equipment)] location with the accuracy of an area ... [and] using subscription data held in a subscriber database such as a Home Location Register (HLR) or Home Subscriber Server (HSS)."). Appellants also contend that "Motegi does not allow the base station and the location information management server to, eventually, interwork over an interface that would connect the base station and the location information management server." See App. Br. 12. We disagree. As shown in Figure 2 of Motegi, the location information management server is comprised of location registration area management table, a deleting unit, and a network communication unit. Motegi ,r 61, Fig. 2. Motegi discloses that the network communication unit "performs transmission/reception of information to or from each base station ... through the network." Motegi ,r 61. The transmission and reception of information between the location information management server and base stations are all that the claims require. Cf claim 37 (sending a request message from an ENB to the MME and receiving an accept or reject message at the ENB from the MME). Accordingly, we are not persuaded of error. Additionally, Appellants assert the Examiner erred in finding Motegi, alone or in combination with AAP A, teaches or reasonably suggests an ENB sending a request message to an MME to associate the ENB with an 7 Appeal2018-001513 Application 11/556,730 identified Tracking Area. App. Br. 8-19; Reply Br. 2---6. In particular, Appellants argue that rather than sending a "request message" to associate a Tracking Area with an ENB, as recited in the claims, the base station (i.e., Motegi's ENB, as modified by AAPA) issues a "mandate" to a location information management server to add or remove a base station and its accompanying location information to/from a location registration area management table. App. Br. 12-19 (citing Motegi ,r,r 70-71, Fig. 5); Reply Br. 2-6. In other words, Appellants argue the base station in Motegi issues a notification to either add or remove a base station and its accompanying location information and the location information management server does not have the ability ( or opportunity) to accept or reject the notification. See App. Br. 13-14. The Examiner finds the notification from the base station in Motegi teaches the claimed "request message" and that the location information management server responds to the base station with either an accept message (i.e., the notification to the base station that the newly installed base station was successfully registered (S56)) or a reject message (in response to a notification of removal from the base station (i.e., when the outcome of S51 is Yes)). Final Act. 4--5; Ans. 8, 10-11. At the outset, we note independent claim 3 7 recites a method wherein the MME (i.e., location information management server) sends "one of a [sic] accept message and a reject message indicating that the request message is one of accepted and rejected." See claim 37 (emphasis added). Thus, the plain language of claim 37 requires only an accept message or a reject message. 8 Appeal2018-001513 Application 11/556,730 Additionally, we note claim 37 further recites "the ENB having both the capability of receiving an accept message and the capability of receiving a reject message." Neither the claim nor the Specification describes that the ability of the ENB to receive a message is affected by the content (i.e., accepted or rejected) of the received message. Additionally, Appellants do not claim the use of the particular content of the message. Accordingly, the ENB must be, at least, capable of receiving a message from the MME. When construing claim terminology during prosecution before the Office, claims are to be given their broadest reasonable interpretation consistent with the Specification, reading claim language in light of the Specification as it would be interpreted by one of ordinary skill in the art. In re Am. Acad. of Sci. Tech. Ctr., 367 F.3d 1359, 1364 (Fed. Cir. 2004). We are mindful, however, that limitations are not to be read into the claims from the Specification. In re Van Geuns, 988 F.2d 1181, 1184 (Fed. Cir. 1993). Because "applicants may amend claims to narrow their scope, a broad construction during prosecution creates no unfairness to the applicant or patentee." In re ICON Health and Fitness, Inc., 496 F.3d 1374, 1379 (Fed. Cir. 2007) ( citation omitted). Regarding the claimed "request message," we disagree with Appellants that the Examiner erred in finding Motegi' s notification teaches or reasonably suggests the request message. As described in Appellants Specification, "the ENB sends a Tracking Area(s) registration message, or registration request, to the PCE( s ). " Spec. 10: 10-11 ( emphasis added). Continuing, the Specification interchangeably uses the terms. See, e.g., Spec. 10: 15-17 ("When the registration request is accepted, the PCE adds (and/or possibly removes, depending on information within the registration 9 Appeal2018-001513 Application 11/556,730 message) the ENB address in the Radio Access Network entity list.") (Emphases added). Thus, the Specification makes clear that what is sent by the ENB may be referred to as a registration message or request. Accordingly, we agree with the Examiner that Motegi's notification teaches or reasonably suggests the claimed "request message." Further, we agree with the Examiner that the notification by the location information management server to the base station indicating that the newly installed base station has been registered, teaches or reasonably suggests receiving at the ENB (i.e., base station) from the MME (i.e., location information management server), an accept message indicating that the request message (i.e., notification) is accepted. See Final Act. 5. An obviousness analysis "need not seek out precise teachings directed to the specific subject matter of the challenged claim, for a court can take account of the inferences and creative steps that a person of ordinary skill in the art would employ." KSR Int'! Co. v. Teleflex Inc., 550 U.S. 398,418 (2007). Here, an ordinarily skilled artisan would understand that by sending a notification (from the location information management server to the base station) that the base station has been registered, Motegi teaches that the notification (i.e., registration notification request) has been accepted and that the base station will receive the message. For the reasons discussed supra, we are unpersuaded of Examiner error. Accordingly, we sustain the Examiner's rejection of independent claim 37. For similar reasons, we also sustain the Examiner's rejection of independent claim 41, which recites similar limitations and was not argued separately. See App. Br. 19; see also 37 C.F.R. § 4I.37(c)(l)(iv) (2017). Additionally, we sustain the Examiner's rejections of claims 38, 39, 42, 47, 10 Appeal2018-001513 Application 11/556,730 48, 50, and 51, which depend directly or indirectly therefrom and were not argued separately with particularity. See App. Br. 19-20; see also 37 C.F.R. § 4I.37(c)(l)(iv). Claims 43-46, 49, and 52-56 We note, sua sponte, independent claim 43 recites, in relevant part, that the MME has "both the capability of accepting said request and the capability of rejecting said request." Independent claim 53 includes a similar limitation. In rejecting claims 43 and 53, the Examiner relies on the findings made in support of the rejection of independent claim 3 7. See Final Act. 8-9. Claims 43 and 53 are of different scope than claim 37 in that claims 43 and 53 recite that the MME must be capable of accepting and rejecting the registration request. We are not persuaded the Examiner has sufficiently explained how the cited portions of Motegi teaches rejecting a request by responding to a notification of a removal of a base station by deleting its entry from the location registration area management table (see, e.g., Final Act. 4--5; Ans. 8, 10-11). Thus, the Examiner has not shown by a preponderance of evidence how the cited portions of Motegi teach the location information management server (i.e., the claimed MME) is capable of rejecting a registration request. For the reasons discussed supra, and constrained by the record before us, we do not sustain the Examiner's rejection of independent claims 4 3 and 53. Additionally, we do not sustain the Examiner's rejection of claims 44-- 46, 49, 52, and 54--56, which depend directly or indirectly therefrom. 11 Appeal2018-001513 Application 11/556,730 DECISION We affirm the Examiner's decision rejecting claims 37-39, 41, 42, 47, 48, 50, and 51. We reverse the Examiner's decision rejecting claims 43--46, 49, and 52-56. No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a)(l)(iv). See 37 C.F.R. § 41.50(±).
