Office Action

§102
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 § 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. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claims 1-4 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by US 11,877,422 B2 (herein “Franz”). Regarding claim 1. Franz discloses a fluid heat dissipation flat tube structure (Figs. 2 and 7), comprising a flat tube structure body (108), L-type terminals (first L terminal following 704 and 706, second L terminal following 712 and 714) and extending double L-shaped solder terminals (double L terminal following 706 and 710 and 712), wherein each flat tube structure body is an integrally formed structure (the tube structure is integrally formed together to form flow channels). Regarding claim 2. Franz discloses the fluid heat dissipation flat tube structure of claim 1, wherein said flat tube structure body is in welded (col. 6, ll. 12-13) connection with L-type terminals, said L-type terminals are welded to both ends of the flat tube structure body (end at 200 and end at 202). Regarding claim 3. Franz discloses the fluid heat dissipation flat tube structure of claim 2, wherein welded joints of said flat tube structure body and L-type terminals adopt step positioning (Fig. 2 – step positioning of 108 in 110 and 112, fluid opening 304 is smaller than opening for 108). Regarding claim 4. Franz discloses the fluid heat dissipation flat tube structure of claim 1, wherein said flat tube structure body is in welded (col. 6, ll. 12-13) connection with extending double L-shaped solder terminals (108 connected to 110).
