Office Action

§102
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 . Drawings The drawings are objected to because figures 3, 5-6, 8, 11-16 contain blurry texts and/or blurry lines. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Claim Objections Claims 42-43 are objected to because of the following reasons: For claim 42, from the claim language, Examiner assumes that it is the processor circuit that perform the operations. However, Examiner recommends Applicants to further clarify the claim language by changing the phrase “cause the network node to” to “cause the processor circuit to”. Otherwise, if Applicants intends for some other hardware components of the network node to perform the operations, then please amend the claims to include those hardware components and clearly indicate that those hardware components perform the operations. If Applicants intends for any unknown hardware components of the network node to perform the operations, then please clearly states so on record. However, Applicants are reminded that doing so will raise 112 issues since then the claim language would impose no limits as to a particular structure for performing the claimed invention; hence the claims may cover all devices for/ways for performing the claimed functions. As thus, there is a failure to provide a clear-cut indication of claim scope because the functional language is not sufficiently precise and definite, resulting in no boundaries on the claim limitation. For claim 43, from the claim language, Examiner assumes that it is the processor circuit that perform the operations. However, Examiner recommends Applicants to further clarify the claim language by changing the phrase “cause the user equipment to” to “cause the processor circuit to”. Otherwise, if Applicants intends for some other hardware components of the user equipment to perform the operations, then please amend the claims to include those hardware components and clearly indicate that those hardware components perform the operations. If Applicants intends for any unknown hardware components of the user equipment to perform the operations, then please clearly states so on record. However, Applicants are reminded that doing so will raise 112 issues since then the claim language would impose no limits as to a particular structure for performing the claimed invention; hence the claims may cover all devices for/ways for performing the claimed functions. As thus, there is a failure to provide a clear-cut indication of claim scope because the functional language is not sufficiently precise and definite, resulting in no boundaries on the claim limitation. Appropriate correction is required. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
