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 . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 08/28/2019 has been entered 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 and 4 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by CN 107592771 (“WU et al.”). Regarding Claims 1and 4, WU et al. discloses CLAIM 1-an outer section including an outer rail (10), said outer rail (10) having a sliding surface and an extension block (12) formed on said sliding surface; a middle section including a middle rail (20) which is disposed on and slidable along said outer rail (10) to shift said three-section slide rail device from a ret33racted state to a first extended state, and an anti-retraction locking member (21, 22) which is pivotably connected with said middle rail (20) adjacent to a proximal end of said middle rail (20); and an inner section including an inner rail (30) which is disposed on and slidable along said middle rail (20) to shift said three-section slide rail device from the first extended state to a second extended state, said inner rail (30) having an inner surface which faces said middle rail (20), and an abutment plate (31) which is formed on said inner surface adjacent to a proximal end of said inner rail (30), said abutment plate (31) abutting against and urging upwardly said anti-retraction locking member (21, 22) to keep said anti-retraction locking member (21, 22) in the retracted state, wherein, when said inner section is moved relative to said middle section to disengage said abutment plate (31) from said anti-retraction locking member (21, 22), said anti-retraction locking member (21, 22) is permitted to turn downwardly so as to allow said middle section to move relative to said outer section to a short extended state, where said anti-retraction locking member (21, 22) abuts against said extension block (12) to prevent a further extending movement of said middle section relative to said outer section; CLAIM 4- wherein said outer rail (10) further has a second anti-retraction block (11) which is formed on said sliding surface and between said extension block (12) and said proximal end of said outer rail (10), wherein, when said three-section slide rail device is in the short extended state, said anti-retraction locking member (via 22) abuts against said second anti-retraction block (11) so as to prevent retraction of said middle section relative to said outer section. Claims 1 and 4 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by US Pub 20210145173 (“Chen et al.”). Regarding Claims 1 and 4, Chen et al. discloses CLAIM 1-a three-section slide rail device, comprising: an outer section including an outer rail (22), said outer rail (22) having a sliding surface and an extension block formed on said sliding surface; a middle section including a middle rail (24) which is disposed on and slidable along said outer rail (22) to shift said three-section slide rail device from a retracted state to a first extended state, and an anti-retraction locking member (54) which is pivotably connected with said middle rail (24) adjacent to a proximal end of said middle rail (24); and an inner section including an inner rail (26) which is disposed on and slidable along said middle rail (24) to shift said three-section slide rail device from the first extended state to a second extended state, said inner rail (26) having an inner surface which faces said middle rail (24), and an abutment plate (98) which is formed on said inner surface adjacent to a proximal end of said inner rail (26), said abutment plate (98) abutting against and urging upwardly said anti- retraction locking member to keep said anti-retraction locking member (54) in the retracted state, wherein, when said inner section is moved relative to said middle section to disengage said abutment plate (98) from said anti-retraction locking member (54), said anti-retraction locking member (54) is permitted to turn downwardly so as to allow said middle section to move relative to said outer section to a short extended state, where said anti-retraction locking member (54) abuts against said extension block to prevent a further extending movement of said middle section relative to said outer section; CLAIM 4-wherein said outer rail (22) further has a second anti-retraction block (32) which is formed on said sliding surface and between said extension block and said proximal end of said outer rail (22), wherein, when said three-section slide rail device is in the short extended state, said anti-retraction locking member (54) abuts against said second anti-retraction block (32) so as to prevent retraction of said middle section relative to said outer section. Allowable Subject Matter Claims 2-3 and 5 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
