SPRY, LILY P. LOOI, and SHAUN M. CONRAD Appeal2018-003901 Application 14/040,316 1 Technology Center 2100 Before HUNG H. BUI, IRVINE. BRANCH, and JOSEPH P. LENTIVECH, Administrative Patent Judges. BRANCH, Administrative Patent Judge. DECISION ON APPEAL Appellants appeal under 35 U.S.C. § 134(a) from a final rejection of claims 1-25, which are all of the claims pending in the application. We have jurisdiction under 35 U.S.C. § 6(b ). We REVERSE. 1 According to Appellants, the real party in interest is Intel Corporation. App. Br. 2. Appeal2018-003901 Application 14/040,316 Technology The application relates to "[i]mproved power control techniques for integrated peripheral component interconnect express (PCie) controllers." Spec. Abstract Illustrative Claim Claims 1-25 are pending; of these, claims 1, 10, and 20 are independent. Claim 1 is reproduced below for reference: 1. A processor circuit, comprising: an integrated peripheral component interconnect express (PCie) controller; and logic, at least a portion of which is in hardware, the logic to detect a power reduction trigger, disable the integrated PCie controller, and remove power from the integrated PCie controller based on a power removal setting for the integrated PCie controller. References and Rejections2 Claims 1-5, 7-14, and 16-24 stand rejected under 35 U.S.C. § I02(a)(2) as anticipated by Teoh (US 2013/0086400 Al, published April 4, 2013). Final Act. 2-10. Claims 6, 15, and 25 stand rejected under 35 U.S.C. § 103 as unpatentable over Teoh and Jaber et al. (US 2014/0025947 Al, published January 23, 2014). Final Act. 11-12. 2 Rather than repeat the Examiner's positions and Appellants' arguments in their entirety, we refer to the above mentioned Appeal Brief filed November 11, 2017 ("App. Br."), as well as the following documents for their respective details: the Final Rejection mailed January 9, 2017 ("Final Act."), the Examiner's Answer mailed December 28, 2017 ("Ans."), and Appellants' Reply Brief filed February 28, 2017 ("Reply Br."). 2 Appeal2018-003901 Application 14/040,316 ANALYSIS In support of the anticipation rejection of claims 1-5, 7-14, and 16- 24, the Examiner finds Teoh describes "logic ... to detect a power reduction trigger, disable the integrated PCie controller, and remove power from the integrated PCie controller based on a power removal setting," as recited in claim 1. Final Act. 2-3 (citing Teoh ,r,r 20-25). The Examiner finds that "when a PCie controller triggers power gating during ASPM L 1, the PCie controller is required to retain power on the logics that stored the link's context information." Id. (citing Teoh ,r 20). The Examiner further finds that "when a PCie controller exits ASPM L 1 to reenter the fully functional LO state, most of the context of the PCie Link is not exchanged between the Upstream component and Downstream component, wherein not exchanged between the components implies removed power from the controller." Id. ( citing Teoh ,r,r 20-25). The Examiner concludes that "it is[, therefore,] expected that between a PCie controller triggers power gating during ASPM L 1, the PCle controller is required to retain power on the logics that stored the link's context information in order not to lose the context information." Id. The Examiner further finds that The Ll and LO state is showing in the table of PCI specification, summary of PCI express link management states. This is equivalent as Applicant recited removed power from the integrated PCie controller based on a power removing setting. Thus, the prior art teaches the invention as claimed and the claims do not distinguish over the prior art as applied. Ans. 11-12. We are persuaded of error. Specifically, we are not persuaded that "the PCle controller [being] required to retain power on the logics that stored the link's context information in order not to lose the context 3 Appeal2018-003901 Application 14/040,316 information" is equivalent to the claimed "remove power from the integrated PCie controller based on a power removal setting." Final Act. 2-3 (emphasis added); Ans. 11-12; Claim 1. See App. Br. 11-13. The Examiner does not adequately explain this equivalency. Further, we agree with Appellants that "Teoh cites to the PCie base specification and states that the power must continue to be supplied to portions of the PCie controller during [the] LI state." App. Br. 12; see also Teoh ,r 20. Accordingly, we do not sustain the Examiner's rejection of claim 1 and of claims 2-9, which depend therefore. For similar reasons, we also do not sustain the rejections of independent claims 10 and 20, and those that depend therefore. DECISION For the reasons above, we reverse the Examiner's decision rejecting claims 1-2 5. REVERSED 4 Copy with citationCopy as parenthetical citation
