GALLIGAN, KEVIN C. TROCK, and JESSICA C. KAISER, Administrative Patent Judges. KAISER, Administrative Patent Judge. DECISION ON APPEAL Appellants 1 appeal under 35 U.S.C. § 134 from a final rejection of claims 1-20. We have jurisdiction under 35 U.S.C. § 6(b ). We affirm. 1 According to Appellants, the real party in interest is Intel Corporation. (Br. 2.) Appeal2014-007382 Application 13/077,745 EXEMPLARY CLAIM Claim 1, reproduced below, is illustrative of the claimed subject matter with disputed limitations emphasized: 1. A method for wireless communications, comprising: determining setup information of a user equipment (UE), wherein the setup information includes identification of a plurality of radios; detecting in-device coexistence interference by the UE, wherein the UE is configured to communicate by a first radio using a first wireless protocol and a second radio using a second wireless protocol; transmitting in-device coexistence interference information to a receiver to suggest a first time-division multiplexing (TDM) pattern, wherein the in-device coexistence interference information indicates a subset of allowed hybrid automatic repeat request (HARQ) processes; and receiving, by the UE, a discontinuous reception (DRX) configuration to monitor a physical downlink control channel (PDCCH) discontinuously; wherein the DR_X configuration comprises a second TDM pattern to operate the first radio during a first duration and to provide an opportunity to operate the second radio during a second duration. REJECTIONS The Examiner made the following rejections: Claims 1-18 and 20 stand rejected under 35 U.S.C. § 103(a) as being unpatentable over Dayal (US 2011/0243047 Al; published Oct. 6, 2011) and Seok (US 2010/0031110 Al; published Feb. 4, 2010). (Final Act. 3-13.) Claim 19 stands rejected under 35 U.S.C. § 103(a) as being unpatentable over Dayal and Seok, in combination with an additional reference. (Id. at 14.) 2 Appeal2014-007382 Application 13/077,745 ISSUES The issues raised by Appellants' arguments are: 1. Did the Examiner err in finding Seok teaches or suggests "the in-device coexistence interference information indicates a subset of allowed hybrid automatic repeat request (HARQ) processes," as recited in claim 1, and similarly recited in claims 10, 15, and 18? 2. Did the Examiner err by improperly combining Dayal and Seok to conclude that claims 1, 10, 15, and 18 would have been obvious? ANALYSIS We have reviewed the Examiner's rejections in light of Appellants' arguments that the Examiner has erred. We disagree with Appellants' conclusions. We adopt as our own the findings and reasons set forth by the Examiner in the Final Action (Final Act. 3-14) from which this appeal is taken, the Advisory Action (Adv. Act. 2 (mailed Aug. 12, 2013)), and the findings and reasons set forth in the Examiner's Answer in response to Appellants' Appeal Brief (Ans. 4--7). We highlight and address specific findings and arguments for emphasis as follows. "indicat[ing] a subset of allowed [HARQ] processes" Appellants argue Seok does not teach or suggest "the in-device coexistence interference information indicates a subset of allowed hybrid automatic repeat request (HARQ) processes," as recited in claim 1, and similarly recited in claims 10, 15, and 18. (Br. 14--15.) Specifically, 3 Appeal2014-007382 Application 13/077,745 Appellants argue Seok's HARQ acknowledgement does not "indicate[] that any particular HARQ processes are allowed." (Id. at 15.) We are not persuaded. The Examiner finds, and we agree, Seok teaches transmission of a HARQ acknowledgement in response to a received HARQ process block. (Ans. 5 (citing Seok i-f 138); Final Act. 5.) The Examiner further finds, and we agree, that the HARQ acknowledgement indicates subsets of allowed HARQ processes because the HARQ acknowledgement verifies the successful transmission of a HARQ process block. (Ans. 5; Seok i-f 133-34.) Appellants' argument that Seok' s HARQ acknowledgement does not "even pertain to the concept of the allowability of HARQ processes" (Br. 15) is not persuasive. Seok's HARQ acknowledgement "indicates" an "allowed" HARQ process as recited by the claim because the HARQ acknowledgement is transmitted in response to a successfully implemented HARQ process. (Seok i-f 133-34.) That is, the HARQ acknowledgement indicates the successful use, and therefore the allowability, of a HARQ process because it is a response to a successful HARQ process. Further, Appellants' arguments that Seok's HARQ acknowledgement does not indicate "any particular HARQ processes" (Br. 15) are not persuasive. We observe that the claim recites indication of "a subset" of HARQ processes. Under a broadest reasonable interpretation, a "subset" encompasses the entire set (i.e., it can be the same or smaller than a given set). Accordingly, Seok's HARQ acknowledgement necessarily indicates some subset of HARQ processes within the given set of all HARQ processes because a subset of HARQ processes can be any or all HARQ processes. Moreover, the Examiner finds Seok's HARQ acknowledgement is 4 Appeal2014-007382 Application 13/077,745 implemented for particular type of HARQ, stop-and-wait HARQ. (See Ans. 7 (citing Seok i-f 59); see also Seok i-f 130-31.) Seok's HARQ acknowledgement, therefore, indicates the successful use of stop-and-wait HARQ. Accordingly, we are not persuaded of error in the Examiner's finding that the combination of Dayal and Seok teaches or suggests "the in-device coexistence interference information indicates a subset of allowed hybrid automatic repeat request (HARQ) processes," as recited in claim 1, and similarly claims 10, 15, and 18. Motivation to Combine Dayal and Seok Appellants argue "a person of ordinary skill in the art would not be motivated to combine the downlink bitmap in Seok with the uplink message in Dayal" for two reasons. (Br. 16-17.) First, Appellants argue there is no "logical basis for including [Seok's] HARQ reporting" messages in Dayal's transmitted request message. (Id. at 16.) Second, Appellants argue there is no "logical basis for implementing the group response scheme" transmitted from Seok's base station by Dayal's user equipment. (Id. at 16-17.) We are not persuaded. In identifying a reason that would have prompted a person of ordinary skill in the relevant field to combine the prior art teachings, the Examiner must provide articulated reasoning with some rational underpinning to support the legal conclusion of obviousness. KSR Int'! Co. v. Teleflex Inc., 550 U.S. 398, 418 (2007). The Examiner finds, and we agree, Dayal teaches a multi-radio wireless communication system which transmits coexistence information in a message from user equipment to a base station (i.e., a receiver). (Final Act. 4 (citing Dayal i-fi-171, 72, 81).) As 5 Appeal2014-007382 Application 13/077,745 discussed supra, the Examiner also finds Seok teaches transmission of HARQ acknowledgement messages. (Ans. 5 (citing Seok i-f 138); Final Act. 5.) The Examiner combines Dayal's transmission with Seok's HARQ acknowledgements in one message, reasoning that the combination "minimize[ s] the number of messages that must be sent to the receiver." (Ans. 6; Final Act. 5.) Appellants' first argument identifying differences in the type of messages sent by Dayal and Seok does not persuasively explain why a person of ordinary skill would not have found it obvious to combine different types of data into a consolidated message. (See Br. 16.) The Examiner's reason to combine Dayal and Seok, minimizing sent messages, has a rational underpinning because minimizing sent messages can decrease the processing overhead required to send multiple individual messages. (See Ans. 6.) Whether or not Seok's and Dayal's messages contain different types of data, consolidating messages with different data types still minimizes the number of sent messages. Appellants secondly argue that there is no logical basis for implementing Seok's group response scheme by Dayal's user equipment because Seok teaches a group of HARQ acknowledgements from a base station rather than individual HARQ acknowledgements from user equipment. (Id. at 16-17.) However, the Examiner finds, and we agree, that user equipment can transmit HARQ acknowledgements (Ans. 7 (citing Seok i-f 210)) and that user equipment can transmit multiple HARQ messages (id. (citing Seok i-fi-1 57, 59) ). Because Seok teaches user equipment can send HARQ acknowledgements and multiple HARQ messages, and the Examiner's motivation to consolidate messages has a rational underpinning 6 Appeal2014-007382 Application 13/077,745 as discussed supra, we are also persuaded that the Examiner provided a rational underpinning for the consolidated message sent by Seok's user equipment to include group HARQ acknowledgements. Accordingly, we find the Examiner has articulated sufficient reasoning with a rational underpinning to support the combination of Dayal and Seok. Claims 2-9, 11-14, 16, 17, 19, and 20 Appellants do not argue separate patentability for dependent claims 2- 9, 11-14, 16, 17, 19, and 20, which depend directly or indirectly from claims 1, 10, 15, or 18. (Br. 17.) For the reasons set forth above, therefore, we are not persuaded the Examiner erred in rejecting these claims. See In re Lovin, 652 F.3d 1349, 1356 (Fed. Cir. 2011) ("We conclude that the Board has reasonably interpreted Rule 41.3 7 to require applicants to articulate more substantive arguments if they wish for individual claims to be treated separately."). Accordingly, we sustain the Examiner's rejections of claims 2-9, 11-14, 16, 17, 19, and 20. See 37 C.F.R. § 41.37(c)(l)(iv). DECISION For the above reasons, the Examiner's decision to reject claims 1-20 is affirmed. 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). AFFIRMED 7 Copy with citationCopy as parenthetical citation
