Office Action

§102 §112
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1, 5, 6, 8-10, 11, 14, 15, 17-18, 20 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 1 recites the limitation "the first cell DTX DRX configuration" in line 7. There is insufficient antecedent basis for this limitation in the claim. It is further unclear on if "the first cell DTX DRX configuration" is referring to “first configuration parameters of a cell discontinuous transmission (DTX) discontinuous reception (DRX) configuration for the first cell”. Examiner suggests clarifying such subject matter. Claim 5 recites the limitation "a cell DTX DRX configuration" in lines 2-3. It is unclear on if "a cell DTX DRX configuration" is referring to “a cell discontinuous transmission (DTX) discontinuous reception (DRX) configuration for the first cell” in the independent claim or is a different configuration. Claim 6 recites the limitation "a cell DTX DRX configuration" in line 5. It is unclear on if "a cell DTX DRX configuration" is referring to “a cell discontinuous transmission (DTX) discontinuous reception (DRX) configuration for the first cell” in the independent claim or is a different configuration. Dependent Claim 8 recites the limitation “first configuration parameters comprise a first parameter indicating whether the cell DTX DRX configuration is activated in response to receiving the first configuration parameters”. However the independent claim recites “activating or deactivating the first cell DTX DRX configuration in response to receiving the downlink control information and based on the value of the field”. It is thus unclear on what is meant by such limitation. Are “the cell DTX DRX configuration” and “the first cell DTX DRX configuration” two different configurations or the same configuration? Is DTX DRX configuration being activated via “first configuration parameters” and “downlink control information”? Examiner suggests clarifying such subject matter. Dependent claim 9 recites the limitation “the first parameter indicates that the cell DTX DRX configuration is deactivated in response to receiving the first configuration parameters and that activation of the cell DTX DRX configuration is further in response to receiving a downlink control information”. However the independent claim recites “activating or deactivating the first cell DTX DRX configuration in response to receiving the downlink control information and based on the value of the field”. It is thus unclear on what is meant by such limitation. Are “the cell DTX DRX configuration” and “the first cell DTX DRX configuration” two different configurations or the same configuration? Is DTX DRX configuration being deactivated via “first configuration parameters” and “downlink control information”? Furthermore claim 8 (in which claim 9 depends on) recites “a first parameter indicating whether the cell DTX DRX configuration is activated”. It is unclear on how a first parameter may indicate activated and deactivated. Examiner suggests clarifying such subject matter. Claim 10 recites the limitation “a plurality of cell DTX DRX configuration,”. It is unclear on exactly what is meant and Examiner believes the limitation should read “a plurality of cell DTX DRX configurations,”. Claim 11 recites the limitation "the first cell DTX DRX configuration" in line 11. There is insufficient antecedent basis for this limitation in the claim. It is further unclear on if "the first cell DTX DRX configuration" is referring to “first configuration parameters of a cell discontinuous transmission (DTX) discontinuous reception (DRX) configuration for the first cell”. Examiner suggests clarifying such subject matter. Claim 14 recites the limitation "a cell DTX DRX configuration" in lines 3. It is unclear on if "a cell DTX DRX configuration" is referring to “a cell discontinuous transmission (DTX) discontinuous reception (DRX) configuration for the first cell” in the independent claim or is a different configuration. Claim 15 recites the limitation "a cell DTX DRX configuration" in line 5. It is unclear on if "a cell DTX DRX configuration" is referring to “a cell discontinuous transmission (DTX) discontinuous reception (DRX) configuration for the first cell” in the independent claim or is a different configuration. Dependent Claim 17 recites the limitation “first configuration parameters comprise a first parameter indicating whether the cell DTX DRX configuration is activated in response to receiving the first configuration parameters”. However the independent claim recites “activate or deactivate the first cell DTX DRX configuration in response to receiving the downlink control information and based on the value of the field”. It is thus unclear on what is meant by such limitation. Are “the cell DTX DRX configuration” and “the first cell DTX DRX configuration” two different configurations or the same configuration? Is DTX DRX configuration being activated via “first configuration parameters” and “downlink control information”? Examiner suggests clarifying such subject matter. Dependent claim 18 recites the limitation “the first parameter indicates that the cell DTX DRX configuration is deactivated in response to receiving the first configuration parameters and that activation of the cell DTX DRX configuration is further in response to receiving a downlink control information”. However the independent claim recites “activate or deactivate the first cell DTX DRX configuration in response to receiving the downlink control information and based on the value of the field”. It is thus unclear on what is meant by such limitation. Are “the cell DTX DRX configuration” and “the first cell DTX DRX configuration” two different configurations or the same configuration? Is DTX DRX configuration being deactivated via “first configuration parameters” and “downlink control information”? Furthermore claim 17 (in which claim 18 depends on) recites “a first parameter indicating whether the cell DTX DRX configuration is activated”. It is unclear on how a first parameter may indicate activated and deactivated. Examiner suggests clarifying such subject matter. Claim 20 recites the limitation "the first cell DTX DRX configuration" in lines 9-10. There is insufficient antecedent basis for this limitation in the claim. It is further unclear on if "the first cell DTX DRX configuration" is referring to “first configuration parameters of a cell discontinuous transmission (DTX) discontinuous reception (DRX) configuration for the first cell”. Examiner suggests clarifying such subject matter. Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
