SILVERMAN, and MATTHEW J. McNEILL, Administrative Patent Judges. SILVERMAN, Administrative Patent Judge. DECISION ON APPEAL Appellants appeal under 35 U.S.C. § 134(a) from the Examiner’s Final Rejection of claims 45—53, which constitute the only pending claims. We have jurisdiction under 35 U.S.C. § 6(b). We reverse. STATEMENT OF THE CASE The invention relates to provisioning a Video-On-Demand server. Abstract; Spec. 1:24 to 2:5. Claim 45 is exemplary of the matter on appeal (disputed limitations emphasized): 1 According to Appellants, the real party in interest is ARRIS Enterprises, Inc. Br. 2. Appeal 2016-005575 Application 10/639,006 45. A video-on-demand server, comprising: a plurality of interface modules, each interface module providing a communication interface between the video-on-demand server and a switching network; an interface to a management module, the management module adapted to monitor and provide to the video-on-demand server information on video-on-demand bandwidth utilization of network resources allocated to particular service groups, each service group comprising a plurality of video-on-demand customers sharing a same fixed network bandwidth allocation; each interface module communicatively coupled to a plurality of service groups simultaneously via a plurality of service gateways; a total bandwidth of the server is an aggregate bandwidth of all the interface modules, and is less than an aggregate bandwidth of all service groups assigned to be serviced by the server, the switching network configured to make the server available for receiving video on demand service requests from all of the service group customers simultaneously, the server adapted to dynamically assign bandwidth of the server to service groups, by adapting the switching network to dynamically change communication connections between interface modules and service groups, the adaptations to the switching network based upon information about the bandwidth utilization of network resources received from the management module. Br. 12 (Claims App.). THE REJECTION Claims 45—532 stand rejected under 35 U.S.C. § 103(a) as being unpatentable over Sheeran (US 6,909,726 Bl; iss. June 21, 2005), McHale et 2The heading (Final Act. 2) does not expressly identify claims 45—53 but the context is clear that claims 45—53 are rejected over the identified references. See Final Act. 2—5. 2 Appeal 2016-005575 Application 10/639,006 al. (US 6,014,431; iss. Jan. 11, 200) (“McHale”), and Li et al. (US 6,543,053 Bl; iss. Apr. 1, 2003). Final Act. 2—5. ANALYSIS Appellants argue the Examiner errs in finding Sheeran, McHale, and Li teach the claim 45 limitation: a total bandwidth of the server is an aggregate bandwidth of all the interface modules, and is less than an aggregate bandwidth of all service groups assigned to be serviced by the server, the switching network configured to make the server available for receiving video on demand service requests from all of the service group customers simultaneously. Br. 9-11. According to Appellants: Sheeran teaches that a video server multiplexes many streams into a communication to a service node. Different service nodes receive different multiplexes. Sheeran's conservative and conventional approach is to match the bandwidth of the server to the potential demands of the customers. McHale describes limiting the number of subscribers that can connect to the server at a time through the switching network to a number m that the server can handle. The present invention is not designed this way. The present invention oversubscribes the server by deliberately making it possible for more subscribers than the server can handle to simultaneously make requests with the server. This creates a real risk, by design, that the server will simply fail to meet the demands placed upon it. McHale handles this situation by essentially creating a choke point in the switching network, so that no more subscribers can reach the server simultaneously than the server can handle. Although this suggests a server that is underpowered, it does not suggest underpowering the server by design, but rather that if subscriber demands come to exceed server capability (for example, a server becomes insufficient due to subscriber growth), the network itself may be operated to prevent the server from receiving excess demand requests. 3 Appeal 2016-005575 Application 10/639,006 Id. at 9. Appellants argue “there is no obvious suggestion in Sheeran that the server should be deliberately underpowered relative to the potential demands it might have to meet from customers” and “should this situation undesirably arise, any mitigation suggested by McHale involves protecting the server from ever receiving excess demand requests.” Br. 10. Appellants further argue, in contrast to Sheeran and McHale, [t]he present application . . . deliberately assumes the risk that service requests reaching the server will be denied due to deliberately mismatching server capacity and potential demand, and mitigates this risk through intelligent and flexible rerouting of requests to different service modules of the server by altering the switching fabric connecting the server to the customers. Id. The Examiner finds the combination of Sheeran, McHale, and Li teaches the limitations of claim 45. Final Act. 9—10; Ans. 6—9. Regarding the disputed limitation, the Examiner finds “Sheeran teaches the switching network is configured to make the server available to all service group customers simultaneously via a plurality of service gateways (fig. 1 (all service nodes are connected to the remultiplexer and server simultaneously nodes meets ‘gateways’)).” Final Act. 3. The Examiner additionally finds “Li teaches servers capable of handling simultaneous user requests (col. 1, II. 42-51) which meets ‘receiving video on demand service requests from all of the service group customers simultaneously.’” Id at 4. The Examiner finds McHale teaches the disputed limitation a total bandwidth of the server is an aggregate bandwidth of all the interface modules, and is less than an aggregate bandwidth of all service groups assigned to be serviced by the server. Final Act. 3—4\ see also Ans. 6—9. In 4 Appeal 2016-005575 Application 10/639,006 particular, the Examiner finds McHale teaches oversubscription of the server and assigning bandwidth by adapting the switching network to dynamically change communication connections between interface modules and service groups for the benefit of increasing the number of subscribers without increasing the cost of operation. Final Act. 3^4 (citing McHale Fig. 4; 11:56 to 12:27; 6:18-28). Regarding Appellants’ argument “should this situation [oversubscription] undesirably arise, any mitigation suggested by McHale involves protecting the server from ever receiving excess demand requests [choking the server],” the Examiner “disagrees because McHale’s method of handling high bandwidth applications will allow Sheeran to accommodate many more subscribers without the need for additional bandwidth in the Sheeran system.” Ans. 9. We are persuaded by Appellants’ arguments regarding the limitation the switching network configured to make the server available for receiving video on demand service requests from all of the service group customers simultaneously. While the Examiner relies on the teachings of Sheeran and Li for this limitation, supra, the Examiner does not address how this finding is consistent with McHale’s teaching of oversubscription and choking the server wherein the server is protected from receiving excess demand requests (does not receive service requests from all of the service group customers simultaneously). Therefore, based on the record, because McHale teaches limiting service requests to the server, the combination of the teachings of Sheeran, McHale, and Li suggested by the Examiner would not result in the claimed invention, as understood by one of ordinary skill in the art. 5 Appeal 2016-005575 Application 10/639,006 The Examiner presents insufficient findings as required for obviousness. In particular, the Examiner’s findings do not set forth sufficient facts to teach the limitation to make the server available for receiving video on demand service requests from all of the service group customers simultaneously. As stated by the Supreme Court, the Examiner’s obviousness rejection must be based on “some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.” KSRInt’l. Co. v. Teleflex, Inc., 550 U.S. 398, 418 (2007) (quoting In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006)). In view of the above, we do not sustain the rejection of claim 45, and independent claims 51 and 52. We also do not sustain the rejection of dependent claims 46—50 and 53. Cf. In reFritch, 972 F.2d 1260, 1266 (Fed. Cir. 1992) (“[Djependent claims are nonobvious if the independent claims from which they depend are nonobvious . . . .”). Because our decision with regard to the disputed limitation is dispositive of the rejection of these claims, we do not address additional arguments raised by Appellants. DECISION We reverse the Examiner’s decision rejecting claims 45—53. REVERSED 6 Copy with citationCopy as parenthetical citation
