Office Action

§102 §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 . 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 2-7, 16-18 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 2 recites “a side wall of the chamber” in line 2. It is unclear if this side wall is the same as “a wall” as claimed in claim 1. Claims 3-6 also rejected for depending on rejected claim 2. Claim 6 depending on claim 2 recites “a first suture needle” while claim 2 already recites “a suture needle”. It is unclear if this is a different suture needle or the same. Claim 7 recites “a side wall of the chamber”. Claim 1 recites “a wall”. It is unclear if these are the same structure. Claim 16 recites “a side wall” in line 2. Claim 1 recites “a wall” in line 3. It is unclear if these are the same limitations. Claim 16 recites “one or more needle guide holes”, while claim 1 from which it depends already recites “a first needle guide hole”. It is unclear if the one or more needle guide holes includes the previous first needle guide hole or is structure in addition to the first needle guide hole. Claim 17, recites “the needle guide holes”. There is lack of antecedent basis for this limitation in the claims. Claim 18 recites “the suture needle”. There is lack of antecedent basis for this limitation in the claims. 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. Claim(s) 1-7, 11, 16, 18-19, 21 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by US 6,200,327 to Assal. Assal teaches: Claim 1: A tendon suture instrument, comprising a chamber (space between prongs 36 and 37, Fig. 1 reproduced with annotation below) for accommodating a tendon tissue (intended use), wherein one end of the chamber is provided with an opening (Fig. 1 reproduced with annotation below), the opening is arranged to allow the tendon tissue to enter the chamber, the chamber is defined by a wall (inner surface of 36 and 37, Fig. 1 reproduced with annotation below), and a first wiring channel (38, Fig. 1 reproduced with annotation below) and a first needle guide hole (opening on each side of channel 38, Fig. 1 reproduced with annotation below) are arranged on the wall. Claim 2: The first wiring channel (38, Fig. 1 reproduced with annotation below) comprises the first needle guide hole, a side wall of the chamber comprises a second wiring channel comprising a third needle guide hole, and the first wiring channel and the second wiring channel are distributed on two sides of the chamber (Fig. 1 reproduced with annotation below). Claim 3: The first needle guide hole of the first wiring channel (Fig. 1 reproduced with annotation below) is arranged to guide a suture needle (not yet claimed) to pass through a cross section of the chamber and then exit from the third needle guide hole of the second wiring channel (Fig. 1 reproduced with annotation below) (As shown in Fig. 1, the needle 10 is passing through from the prong 37 across the chamber and through prong 36 via orifices 35 and 38).

Claim 16: A second wiring channel (Fig. 1 reproduced with annotation below) is arranged on a same side as the first wiring channel on a side wall (Fig. 1 reproduced with annotation below) of the chamber, and one or more needle guide holes are arranged on each wiring channel (there are openings/needle guide holes on both ends of each wiring channel, Fig. 1 below). Claim 18: The first wiring channel is close to the second wiring channel (Fig. 1 reproduced with annotation below), or the first wiring channel is arranged parallel to the second wiring channel (Fig. 1 reproduced with annotation below), and the suture needle (such as needle 10, Fig. 1) can pass between the first wiring channel and the second wiring channel (functional limitation, the suture needle can pass through the first wiring channel, through the third wiring channel, come back around to the fourth wiring channel and enter through the second wiring channel). PNG media_image3.png 623 680 media_image3.png Greyscale Claim 19: The first wiring channel and the second wiring channel (Fig. 1 reproduced with annotation below) are arranged on a same side on the wall of the chamber, the first needle guide hole and a second needle guide hole (Fig. 1 reproduced with annotation below) are arranged on the first wiring channel, and a third needle guide hole and a fourth needle guide hole (Fig. 1 reproduced with annotation below) are arranged on the second wiring channel; and when first suture is performed (functional limitation), a suture needle (such as needle 10, Fig. 1) enters from the second needle guide hole of the first wiring channel and then exits from the third needle guide hole of the second wiring channel (the needle can enter from the second needle guide hole, through the first wiring channel, then come around and enter through the second wiring channel and exits the third needle guide hole as shown in figure 1 below). PNG media_image4.png 670 698 media_image4.png Greyscale Claim 21: A tendon suture instrument, comprising a chamber (space between prongs 36 and 37, Fig. 1 reproduced with annotation above), wherein one end of the chamber is provided with an opening (Fig. 1 reproduced with annotation above), the chamber is used for accommodating a sutured tendon tissue (Intended use), the tendon tissue can enter the chamber through the opening of the chamber when needing to be sutured (functional limitation), the chamber is defined by a wall (Fig. 1 reproduced with annotation above), and a wiring region (wiring channel, Fig. 1 reproduced with annotation above) is arranged on the wall, wherein one or more needle guide holes (Fig. 1 reproduced with annotation above) are arranged on the wiring region. Claim(s) 1, 7-10, 16-17 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by US 6322571 to Adams.
