Office Action

§102 §103 §112
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 . This is the First Office action on the Merits from the examiner in charge of this application. 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. Claim 10 is 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 10: since claim 1, line 7 recites the blocking feature “arranged on the first rail”, the recitation in claim 10, lines 3-4 of the blocking feature “arranged on the supporting bracket” renders claim 10 indefinite for failing to clearly define the metes and bounds of the claimed invention. It is not clear how it is possible for the blocking feature being arranged on both the first rail and the supporting bracket. Claim 10 will be examined as best understood or so far as definite. 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 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim(s) 9-10, and 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Li in view of USP 10631639 to Chen et al (hereinafter Chen). Li discloses all the elements as discussed above except for the limitations recited in the above-listed claims. However, Chen discloses a slide rail assembly comprising: a first slide rail 30; a second slide rail 32 displaceable relative to the first rail 30 along a longitudinal direction, the second rail 32 comprising a first end portion and a second end portion opposite to the first end portion along the longitudinal direction; a blocking feature 34 arranged on the first rail 30; an engaging member 36; a resilient member 66 configured to provide a resilient force to the engaging member 36; and an operating member 36 located along the longitudinal direction and located adjacent to a lateral side of the second rail 32, the operating member being movably switchable between a first state and a second state; wherein when the second rail is located at a retracted position relative to the first rail, the blocking feature blocks the engaging member applied with the resilient force provided by the resilient member for preventing a displacement of the second rail from the retracted position along a first direction; wherein the operating member is configured to move from the first state to the second state to drive the engaging member, such that the engaging member is not blocked by the blocking feature for allowing the displacement of the second rail from the retracted position along the first direction; a third rail 38 movably mounted between the first rail 30 and the second rail 32; a supporting bracket 26,28 arranged on the first rail 30 and configured to be mounted on a rack 24, and the blocking feature is arranged on the supporting bracket. Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention, in view of Chen, to modify Li to include the limitations in Claim 9 of further comprising a third rail movably mounted between the first rail and the second rail; Claim 10 of further comprising a supporting bracket arranged on the first rail and configured to be mounted on a rack, and the blocking feature is arranged on the supporting bracket; and Claim 20 of further comprising a third rail and a supporting bracket, the third rail being movably mounted between the first rail and the second rail, and the supporting bracket being arranged on the first rail and configured to be mounted on a rack with a reasonable expectation of success in order to increase the overall versatility of the slide rail assembly.
