Office Action

§102 §103
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 . Specification Applicant is reminded of the proper language and format for an abstract of the disclosure. The abstract should be in narrative form and generally limited to a single paragraph on a separate sheet within the range of 50 to 150 words in length. The abstract should describe the disclosure sufficiently to assist readers in deciding whether there is a need for consulting the full patent text for details. Drawings Figure 3 should be designated by a legend such as --Prior Art-- because only that which is old is illustrated. See MPEP § 608.02(g). Corrected drawings in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. The replacement sheet(s) should be labeled “Replacement Sheet” in the page header (as per 37 CFR 1.84(c)) so as not to obstruct any portion of the drawing figures. If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. 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. Claim(s) 1-3 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Haslebacher (US 2012/0031059 A1). Haslebacher ‘059 teaches an air filter comprising a rectangular pleated filter body (230) with four sides, a rectangular frame (receptacle 231) surrounding the filter, and a gasket between the filter frame and the filter body along the four sides, wherein the gasket has four sides joined at corner portions and wherein the corner portions have mating polygonal convex and concave parts (290,291) (see figures 5-10, paragraphs 54-61). Claim Rejections - 35 USC § 103 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. Claim(s) 1-3 is/are rejected under 35 U.S.C. 103 as being unpatentable over JP 2008-6416 A in view of Haselbacher ‘059. JP ‘416 discloses an air filter comprising a rectangular pleated filter body (1) with four sides, a rectangular filter frame (5) surrounding the filter body, and a gasket (6) between the frame and the filter body (see figure 1, paragraphs 7-10 of the machine-generated English translation). The instant claims differ from JP ‘416 in that the gasket has end portions joined at corners using mating convex and concave parts. Haselbacher ‘059 discloses a filter with a mated segmented gasket as described in paragraph 6 above. It would have been obvious to a person having ordinary skill in the art at the time of the invention to modify the gasket of JP ‘416 by using the mated gasket portions of Haselbacher ‘059 in order to provide interlocking joints that preclude longitudinal displacement of the gasket elements after they are joined. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. The additional references listed on the attached PTO-892 form disclose filter frame and sealing arrangements.
