Office Action

§102 §103 §112
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. Specification The abstract of the disclosure is objected to because there appears to be a typo regarding “The needle hub has aa distal path” as opposed to “The needle hub has a distal path…”. A corrected abstract of the disclosure is required and must be presented on a separate sheet, apart from any other text. See MPEP § 608.01(b). The disclosure is objected to because of the following informalities: In paragraph [0130], “the tubing 148” should be corrected to “the tubing 158 ” In paragraphs [0143] and [0147], “the catheter unit 104” should be corrected to “the catheter unit 102 ” In paragraph [0154], “the ultrasound probe 116” should be corrected to “the ultrasound probe 226 ” In paragraph [0158], “the catheter hub 110” should be corrected to “the needle hub 110” In paragraph [0159], “the working platform 134” should be corrected to “the working platform 136 ” Appropriate correction is required. Claim Objections Claim 36 is objected to because there is a typo regarding “passing a guidewire through proximal path,…” as opposed to “passing a guidewire through the proximal path,…” in line 14. Appropriate correction is required. 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 appl icant regards as his invention. Claims 34-35 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. Regarding claim 34, the limitation “a guidewire is partly located inside the tubing and partly located inside the needle” in lines 2-3 renders the claim indefinite. It is unclear if the catheter assembly includes two guidewires: “ a guidewire extends through both the distal path, the proximal path, and at least part of the needle lumen ” as required by claim 21 and also a second “a guidewire” partly located inside the tubing and needle as required by claim 34 , or if “a guidewire” introduced in claim 34 is the same guidewire introduced in claim 21. For examination purposes, “a guidewire” introduced in claim 34 has been interpreted to be the same guidewire introduced in claim 21. It is suggested to amend claim 34 to: “ The catheter assembly according to claim 21, wherein a tubing is attached to the needle hub and wherein a the guidewire is partly located inside the tubing and partly located inside the needle. ”, or similar. Claim 35 is rejected for being dependent on claim 34. Claim Rejections - 35 USC § 102 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 ( i.e., changing from AIA to pre-AIA ) 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. 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)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale , or otherwise available to the public before the effective filing date of the claimed invention.
