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 .
Priority
Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55.
Information Disclosure Statement
The references listed in the Information Disclosure Statement(s) filed on 5/20/2025, 7/16/2025 have been considered by the examiner (see attached PTO-1449 form or PTO/SB/08A and 08B forms).
Claim Rejections - 35 USC § 101
35 U.S.C. 101 reads as follows:
Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title.
Claims 1-20 are rejected under 35 U.S.C. 101 because the claimed invention is directed to an abstract idea without significantly more. The claim(s) (independent claims 1 and 12 in particular) recite(s) “receiving an equivalent channel ratio” on lines 2-6 (i.e. data gathering), and “obtaining a first precoding matrix” on lines 7-9 (considered as a “mental process” that can obtained or determined using pencil and paper).
This judicial exception is not integrated into a practical application because the receiving of a data value (“ratio”) and the mental process of obtaining of a precoding matrix are merely abstract ideas with no change or transformation to a machine/structure or data signal to be transmitted. The claim(s) does/do not include additional elements that are sufficient to amount to significantly more than the judicial exception because the additional elements only amount to further details concerning the gathered data value (ratio) and the determined precoding matrix obtained via the mental process. The obtained values are not applied to any particular useful method for communication of a data signal. Claim 12 recites an apparatus with a transceiver and processor performing the abstract ideas of claim 1. However, the mere implementation of a abstract ideas by “a transceiver” and “a processor” are not considered significantly more than the abstract idea and are not indicative into a practical application.
Dependent claims 2-11 and 13-20 only further specify the abstract ideas without any practical application, and are also rejected under §101.
It is suggested to applicant to amend the claims to include a practical application such as applying “first precoding matrix” to a signal, and transmitting the resulting precoded signal.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
Na et al. (US 2015/0295671) discloses a transmission system in which an optimized precoding matrix is obtained based on an equivalent channel matrix.
