Office Action

§112
DETAILED ACTION This is a non-final rejection in response to application filed 9/28/23. Claims 1-15 are currently pending. 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 1-14 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 the limitation "an end of each of a distal part and a proximal part is open". It is unclear of the distal part has two open ends and the proximal part has two open ends or if each part has just a single opening. Claim 1 recites the limitation "a paddle formed to extend from the end of the distal part of the needle”. It is unclear what direction the paddle is extending. Claim 4 recites the limitation " a virtual line formed to extend from one surface of an upper end of the needle”. It is unclear what structure is needed to form a virtual line. Needles are cylindrical; thus it is unclear which surface is being referred to. Subsequent dependent claims are further rejected. Allowable Subject Matter Claim 15 is allowed. The following is a statement of reasons for the indication of allowable subject matter: The closes prior art of record is to Schmieding et al. and Dean and McGregor et al.. The prior art of record teaches an injection device but fails to teach a paddle as claimed, in particular having a maximum width of the paddle being less than or equal to an outer diameter of the needle. It would not have been obvious to modify the art of record.
