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 Objections Claim 18 is objected to because of the following informalities: claim 18 recites “the least part surface” this should be “the at least part surface”. 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.

Regarding claim 2, Stefansen discloses that the stop feature 403 comprises a surface and the trigger arm 313 is configured to cooperate with said surface of said stop feature (fig. 3a). Regarding claim 4, Stefansen discloses that the trigger arm 311 comprises a projection 312 engaging the stop feature (fig. 3a). Regarding claim 6, Stefansen discloses a needle guard 150, wherein an axial movement of the needle guard towards the drive chassis engages the release mechanism in order to release the fixing of the drive chassis with respect to the housing on activation of the autoinjector (page 5, para. 0072; fig. 3c). Regarding claim 7, Stefansen discloses that the axial movement of the needle guard 150 is configured to deflect the trigger arm of the release mechanism in a direction transverse thereto (fig. 3d; page 5, para. 0072). Regarding claim 8, Stefansen discloses that the needle guard comprises a plunger arm having a blocking rib (see fig. 3a annotated below).
