Office Action

§112
DETAILED ACTION The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . 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. Priority Receipt is acknowledged of papers submitted under 35 U.S.C. 119(a)-(d), which papers have been placed of record in the file. Election/Restrictions Applicant's election with traverse of electing Group I (claims 1-10) in the reply filed on June 18, 2026 is acknowledged. Groups I and II are based on a common inventive concept and are not patentably distinct from each other and the claims could be searched by one examiner without undue effort. This is not found persuasive because Group I, Claims 1-10, drawn to an ink jet recording method, classified in B41M 5/502 and Group II Claim 11, drawn to an ink jet recording apparatus, classified in B41F 19/02, so the inventions require a different field of search (e.g., searching different classes /subclasses or electronic resources, or employing different search strategies or search queries). The requirement is still deemed proper and is therefore made FINAL. Claim 11 is withdrawn from further consideration pursuant to 37 CFR 1.142(b), as being drawn to nonelected inventions, there being no allowable generic or linking claim. Applicant timely traversed the restriction (election) requirement in the reply filed on June 18, 2026. 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 1-10 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 pre-AIA the applicant regards as the invention. Claim 1 recites the limitation "the reaction liquid". There is insufficient antecedent basis for this limitation in the claim. Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to HAI YAN ZHANG whose telephone number is (571)270-7181.
