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 . Information Disclosure Statement The information disclosure statement of 11/07/2024 has been received and reviewed. Claim Objections Claim 20 is objected to because of the following informalities: Claim 20, line 4, “a frame or wall” should be “the frame or wall”. Appropriate correction is required. 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(s) 1-2, 17, and 20 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by NPL cited by applicant (Pemko). Regarding claim 1, Pemko discloses: A release stop (page 2) for a barrier (door seen in page 4), the release stop comprising: a support member (230, see fig 1 below) configured to be operatively coupled with a frame or wall (fig 1); a stop member (250) operatively coupled with the support member; a cover (300, see fig 2 below) operatively coupled to the support member and the stop member (fig 2); and a release lock (ERS seen in page 2 and 11) operatively coupled to the support member, the stop member (pages 11 and 12), or the cover; wherein with the release lock in a first position (when pin is not inserted into ERS) the stop member is restricted from moving with respect to the support member, and with the release lock in a second position (when pin is inserted into ERS, see fig 1 below) the stop member is allowed to move with respect to the support member.

Regarding claim 17, Pemko discloses: A release lock (ERS) for a release stop (page 2), the release lock comprising: a lock body (B, see fig 3 below); and one or more lock projections (P) extending from the lock body; wherein the one or more lock projections restrict a cover (C) of the release stop from moving (by restricting the channel in the closed position) with respect to a stop member (250) or a support member (230) of the release stop. PNG media_image3.png 435 304 media_image3.png Greyscale Fig 3 Regarding claim 20, Pemko discloses: A method of using an anti-obstruction system for allowing a barrier (door seen in page 4) that swings inwardly to swing outwardly (page 4), the anti-obstruction system comprising a double swing hinge (110, see fig 4 below) operatively coupled adjacent a first edge (top edge seen in fig 4) of the barrier and to a frame or a wall (bottom wall seen in fig 4), and a release stop (page 2) comprising a support member (230) operatively coupled with a frame or wall (fig 1), a stop member (250) operatively coupled with the support member, a cover (300) operatively coupled to the support member and the stop member, and a release lock (ERS) operatively coupled to the support member, the stop member, or the cover; the method comprising: disengaging the release lock from a first position (fig 2) in which the stop member is restricted from moving with respect to the support member into a second position (fig 1) that allows the stop member to move with respect to the support member; and swinging to the barrier outwardly past the stop member (page 4). PNG media_image4.png 508 352 media_image4.png Greyscale Fig 4 Allowable Subject Matter Claims 3-16 and 18-29 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.
