Office Action

§101 §102
DETAILED ACTION 1. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . 2. 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 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. 3. Claims 1-20, filed on 3/27/2025, are pending in this office action. Information Disclosure Statement 4. Initialed and dated copy of Applicant’s IDs form 1449, filed 3/27/2025, is attached to the instant Office action. Claim Rejections - 35 USC § 101 5. 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. 6. Claim 16-20 are rejected under 35 U.S.C. 101 because the claimed invention is directed to non-statutory subject matter. Claims 16-20 are directed towards a system claim, but does not necessarily claim statutory hardware embodiments of the system claim. The entity linking system can be interpreted as software, as there are no terms in the limitations that are defined in the specification as being hardware components, nor are there any limitations in the claim that specifically discloses hardware, such as a processor or memory. The claim recites a graph generation moule, a graph neural network, an embedding space similarity module, and a recommendation module; the specification specifically states in paragraph [0027]: ”As used herein, the term "module" can refer to a computer-related entity, either hardware, a combination of hardware and software, software, or software in execution.”, meaning solely software. To make the system claim statutory, hardware embodiments supported in the specification, as well as a processor executing steps, right after the preamble are needed. Proper correction is required. Claim Rejections - 35 USC § 102 7. 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)(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. 8.
