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 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. Claims 1 and 2 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Richardson (US 5,054,159). As to claim 1, Richardson includes a lawn blower apparatus (Embodiment of Fig. 4) comprising: an air tube (E, N) for directing air flow from a nozzle (The opening of N; Fig. 4), said air tube having an exterior surface (The outer surface of E/N); a dislodging component (16; Fig. 4) attached to the exterior surface of said air tube wherein said dislodging component is perpendicular to said exterior surface (Fig. 4) and is attached in proximity to (next to) the nozzle of said air tube, such that said dislodging component loosens or dislodges debris which can thereafter be removed by air force out of said nozzle (column 5, lines 3-7). As to claim 2, Richardson includes a lawn blower apparatus (Embodiment of Fig. 11) comprising: an air tube (E, N) for directing air flow from a nozzle (The opening of N; Fig. 4), said air tube having an exterior surface (The outer surface of E/N); a dislodging component (10, 18, 20) attached to the exterior surface of said air tube, the dislodging component having a first segment (20; Fig. 11) for loosening debris that is perpendicular to the surface and a second segment (10) that is parallel to said exterior surface of the air tube (Fig. 8 and 11), the dislodging component is configurable to be either in a storage position (The position in which the component or the blower is in storage) or in a utility position (The position in which the component or the blower is in use), wherein in said utility position, the second segment of the dislodging component extends past the nozzle of the air tube (The second segment [10] of the component extends down past the nozzle) and the first segment of the dislodging component extends past the nozzle and points towards the ground where it is used to loosen debris (The first segment [20] of the component extends down past the nozzle and points in the direction of the ground; Fig. 1 and 11).
