Appropriate correction is required. Claim Rejections - 35 USC § 102 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. Claims 1-9 and 11-19 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Fukuma (US 2011/0002497). Regarding claim 1, an invention relating to headphone device, Fukuma discloses (Figs. 1 & 7-8) a medical device (100) [Note, headphones are used by surgeons in procedures for informative purposes such as emitting a tone to a surgeon during an ophthalmic procedure to inform the surgeon that a proper depth has been achieved, headphones can be used in a surgical procedure for intracranial noise suppression, or headphones can provide music to a patient during medical procedure] comprising: at least two housing portions (see annotated figure below) joined together at at least one sacrificial joint (see annotated figure below) [i.e. joined prior to shortening of the band 104], wherein each housing portion comprises at least one secondary joining portion (see annotated figure below) configured for joining to at least one corresponding secondary joining portion (see annotated figure below) of at least one other housing portion for rejoining the two housing portions together after destructive breaking of the at least one sacrificial joint [i.e. removing links that make up the sacrificial joint and connecting free ends of links that make up at least one secondary joining portion and at least one corresponding secondary joining portion to rejoin the two housing portions] (Par. 0054, 0063, 0073, 0087). PNG media_image1.png 531 480 media_image1.png Greyscale PNG media_image2.png 428 459 media_image2.png Greyscale Regarding claim 2, Fukuma discloses the medical device of claim 1. Fukuma further discloses wherein the at least one sacrificial joint comprises at least one primary joining portion of each of the at least two housing portions, wherein the at least one primary joining portion of a housing portion is bonded to a corresponding primary joining portion of at least one other housing portion [i.e. bonded via elements 132 and 134; Figure 8] (see annotated figure below & Par. 0073). PNG media_image3.png 294 467 media_image3.png Greyscale Regarding claim 3, Fukuma discloses the medical device of claim 2. Fukuma further discloses wherein the at least one secondary joining portion meets the at least one primary joining portion at at least one separation portion [i.e. first side member 131 and the second side member 133 which engage when joint is assembled by connecting two links, see annotated figure below] (Fig. 8; Par. 0073). PNG media_image4.png 325 491 media_image4.png Greyscale Regarding claim 4, Fukuma discloses the medical device of claim 3. Fukuma further discloses wherein the at least one separation portion is configured so that the at least one primary joining portion can be removed upon disassembly of the at least two housing portions during reworking of the medical device, and the at least one secondary joining portion of a housing portion can be joined to the at least one corresponding secondary joining portion of at least one other housing portion to rejoin the at least two housing portions together (Par. 0064-0065). Regarding claim 5, Fukuma discloses the medical device of claim 2. Fukuma further discloses wherein a volume of an enclosure defined by the at least two housing portions (see annotated figure below) joined together is less when the primary joining portions are joined together than when the secondary joining portions are joined together (Par. 0064-0065) [Note, the volume would be less because removing links would decrease the cross-sectional area of the enclosure, and a decrease in area is correlative to a decrease in volume]. PNG media_image5.png 598 505 media_image5.png Greyscale Regarding claim 6, Fukuma discloses the medical device of claim 2. Fukuma further discloses (Fig. 8) wherein the at least one primary joining portion and the at least one secondary joining portion each comprise a flange [i.e. element 131 on each link is considered a flange, see annotated figure below], the flange comprising a joining surface for joining to a corresponding joining surface [i.e. the inside surface of element 133 that engages element 131] of a corresponding flange ( 133) of at least one other housing portion (see annotated figure below, Par. 0073). Note, the annotated figure shows where the corresponding joining surface would be on at least one other housing portion, and where the joining surface would be on at least one primary joining portion and where the joining surface would be on the at least one secondary joining portion. PNG media_image6.png 208 336 media_image6.png Greyscale Regarding claim 7, Fukuma discloses the medical device of claim 6. Fukuma further discloses wherein the joining surfaces of the primary and secondary joining portions are the same size [i.e. the primary and secondary joining surfaces are both the surface of element 131 on different links which have the same size] (Fig. 9D). Regarding claim 8, Fukuma discloses the medical device of claim 2. Fukuma further discloses wherein a plurality of primary joining portions are interleaved with a plurality of secondary joining portions [i.e. a plurality of primary joining portions would be elements 131 between a plurality of secondary joining portions which would be elements 133] (Par. 0069 & 0073). Regarding claim 9, Fukuma discloses the medical device of claim 8. Fukuma further discloses wherein the plurality of secondary joining portions of one of the at least two housing portions contact the plurality of secondary joining portions of another of the at least two housing portions when the primary joining portions are joined [i.e. primary joining portions when removed are joined and the plurality of secondary joining portions of each housing portion are joined to shorten the band] (see annotated figure below & Par. 0064-0065). PNG media_image7.png 466 452 media_image7.png Greyscale Regarding claim 11, Fukuma discloses the medical device of claim 1.
