Office Action

§102 §103 §112
DETAILED ACTION 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 1-20 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. The claims do not particularly point out and distinctly claim the invention, in that the scope of invention has not been sufficiently defined, making the boundaries of the scope of claim language unclear. See MPEP 2173. The claims lack sufficient structural and/or functional language required to clearly define the scope of a distinct operable invention. Some examples of this lack of structural and/or functional language are directed to the following: In claim 1 in the preamble, a quick-disassembly device is set forth, yet it is unclear what type of device or devices the quick-disassembly device is intended to be used with in the context of the claim language. In claim 1, “which are communicated” is unclear and not fully understood in the context of the claim language. In claim 1, an entering state and a locking state have not been adequately defined in the context of the claim language. In claim 1, a “magnetic force” has been set forth yet no magnetic force generating means has been defined to cause such magnetic force. Similar 112 issues as above are found throughout the remainder of 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 1 is rejected under 35 U.S.C. 102(a)(1) as being anticipated by KR 102188857 B1 (KR ‘857). See the figures on pages 17-21. As in claim 1, a quick-disassembly device, comprising a carrier 200 provided with an accommodating cavity and a limiting cavity which are communicated; a connector 100 movably arranged with the carrier relatively, wherein at least an entering state and a locking state are provided on a moving path of the connector, in the entering state, the connector is at least partially accommodated in the accommodating cavity, and in the locking state, the connector is at least partially accommodated in the limiting cavity and relatively fixed with the carrier; and a limiting assembly, comprising a first connecting block and a second connecting block, wherein the first connecting block is arranged in the connector, and the second connecting block is arranged on the carrier; and in the locking state, the connector is abutted against an inner wall of the limiting cavity under a magnetic force between the first connecting block and the second connecting block, and is fixed in the limiting cavity (visible on page 18 in particular). Claim Rejections - 35 USC § 103 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 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claims 2-20 are rejected under 35 U.S.C. 103 as being unpatentable over KR 102188857 B1 (KR ‘857). Regarding each of these claims, the prior art element performs the function specified in the claim in substantially the same manner as the function is performed by the corresponding element described in the specification, and such structure are considered art recognized equivalent structures and would have functional at least equally as well. It would have been obvious to modify the device in this way for the purpose of providing an alternative arrangement that would have functioned at least equally as well. In addition, (a) combining prior art elements according to known methods to yield predictable results; (b) simple substitution of one known element for another to obtain predictable results; (c) use of known technique to improve similar devices in the same way; (c) applying a known technique to a known device ready for improvement to yield predictable have each been held as being obvious to one having ordinary skill in the art. Further, (e) it would be obvious to try such a modification, since choosing from a finite number of identified, predictable solutions, with a reasonable expectation of success has been held as obvious. See KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398 (2007).
