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 . This office action is responsive to the Response to Restriction Requirement filed December 22, 2025. As directed by the election: Claims 10-16 are elected for prosecution on the merits WITHOUT TRAVERSE and Claims 1-9 and 17-20 are withdrawn from consideration by Examiner. Drawings New corrected drawings in compliance with 37 CFR 1.121(d) are required in this application because Figures 1 and 3-6 are informal and contain inconsistent line thickness, gaps in the lines, freehand curves, uneven geometry, and potentially illegible reference numbers upon publication. Namely, Figure 6 contains a scribbled-out reference number. Applicant is advised to employ the services of a competent patent draftsperson outside the Office, as the U.S. Patent and Trademark Office no longer prepares new drawings. The corrected drawings are required in reply to the Office action to avoid abandonment of the application. The requirement for corrected drawings will not be held in abeyance. The drawings are objected to as failing to comply with 37 CFR 1.84(p)(5) because they do not include the following reference sign(s) mentioned in the description: “303” (see page 7, line 34) and “600” (see page 8, line 21). 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. 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 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 12-16 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. The term “highly reactive gas mixture” in Claims 12-16 is a relative term which renders the claim indefinite. The term “highly” is not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention. Allowable Subject Matter Claim 10-16 are allowable over the prior art. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Specifically, various references are cited that provide detail of relevant methods for introducing fuel to the combustion chamber of an engine.
