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 .
Information Disclosure Statement
The information disclosure statement (IDS) submitted on 3/31/25 and 1/7/25 is being considered by the examiner.
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, 6, 11, 16 are 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 “channel state information reference signal (CSI-RS) ports selected by the terminal device correspond to” in lines 5-6. No limitation prior to this establishes channel state reference signal ports nor “selecting” said reference signal ports. Examiner will interpret the claim as best understood.
Claim 1 recites “a space-frequency vector comprising” in lines 9-10. A “first space-frequency vector set” was previously established, but it is unclear if this is referring to a different (second) space-frequency vector set or the first set. Examiner will interpret the claim as best understood.
Claim 1 recites “comprises first information” in line 12. No limitation prior to this establishes first information only “first indication information”. It is unclear if the intended scope was directed towards “first indication information” or a new “first information”. There is insufficient antecedent basis for this limitation in the claim. Examiner will interpret the claim as best understood.
Claims 6, 11, 16 recite similar limitations and are likewise rejected.
Claims 2-5, 7-10, 12-15, 17-20 are dependent and likewise rejected.
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.
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.
Claims 1-3, 6-8, 11-13, 16-18 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Jin et al (Pub No: 2021/0194547).
