Office Action

§102 §112
DETAILED ACTION 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 content of an abstract of the disclosure. A patent abstract is a concise statement of the technical disclosure of the patent and should include that which is new in the art to which the invention pertains. The abstract should not refer to purported merits or speculative applications of the invention and should not compare the invention with the prior art. If the patent is of a basic nature, the entire technical disclosure may be new in the art, and the abstract should be directed to the entire disclosure. If the patent is in the nature of an improvement in an old apparatus, process, product, or composition, the abstract should include the technical disclosure of the improvement. The abstract should also mention by way of example any preferred modifications or alternatives. Where applicable, the abstract should include the following: (1) if a machine or apparatus, its organization and operation; (2) if an article, its method of making; (3) if a chemical compound, its identity and use; (4) if a mixture, its ingredients; (5) if a process, the steps. Extensive mechanical and design details of an apparatus should not be included in the abstract. The abstract should be in narrative form and generally limited to a single paragraph within the range of 50 to 150 words in length. See MPEP § 608.01(b) for guidelines for the preparation of patent abstracts. 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. The language should be clear and concise and should not repeat information given in the title. It should avoid using phrases which can be implied, such as, “The disclosure concerns,” “The disclosure defined by this invention,” “The disclosure describes,” etc. In addition, the form and legal phraseology often used in patent claims, such as “means” and “said,” should be avoided. The abstract of the disclosure is objected to because of speculative applications (e.g. “once washed” “reinstalled onto the elastic section using, for example, the circumferential zipper around the removable section”) and purported merits (e.g. “a comfortable fabric layer” “easily removable” “can be easily reinstalled”). A corrected abstract of the disclosure is required and must be presented on a separate sheet, apart from any other text. See MPEP § 608.01(b). Claim Objections Claims 1-2, 3, 9-10, 12-13, and 17-18 are objected to because of the following informalities: Regarding claims 1, 9, and 17, the limitations “wherein said fitted sheet having a… fastener” should probably be read as “said fitted sheet having a… fastener” Regarding claims 1, 9, and 17, the limitation “wherein first elastic section having a first…” should probably read as “said first elastic section having a first…” Regarding claims 1, 9, and 17, the limitation “wherein second… section having a second…” should probably read as “said second… section having a second…” Regarding claims 1, 9, and 17, every instance of the limitations “..edge proximal to…” should probably read as “…edge is proximal to…”. Regarding claim 2 and 10, every instance of the limitations “wherein said first elastic section having a water-resistant material” should probably read as “wherein said first elastic section comprises a water-resistant material” Regarding claims 4, 13, and 18, the limitations “material different from said second” should probably read as “material is different from said second…” Appropriate correction is required. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claim 12 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Regarding claim 12, the limitation “…of claim 9, said first material selected from a group consisting of a rubber material, a vinyl material, a flannel material, and a canvas material” is recited. However, claim 12 is dependent on claim 9 that previously establishes “first elastic section having a first material selected from a group consisting of a plastic, a stretchable knitted polyester, a cotton, a bamboo, a linen, a silk, a microfiber, and a satin”. The term consisting of considers that no other material is considered by exclusion of ‘consisting of’. However, the dependent claim 12 then tries to expand this list, which leaves a question of how the invention can at it’s independent claim exclude these materials, and then include them simultaneously? The limitation is convoluting and fails to include the antecedent features of the claim and may arise to a matter of 112d; it is considered claim 12 should likely be cancelled and claims 13/15 are dependent on claim 12. However, clarity and explanation is respectfully requested and otherwise amendment is necessary. For the purposes of examination, the claim is considered to consider a vinyl (plastic) flannel (knitted polyester/cotton/linen) and canvas (polyester/cotton/linen/silk/microfiber/satin) material to anticipate. Though it is noted that such consideration thereby is anticipated by claim 9 as no substantive matter Is considered added to the scope of the claimed invention. Claims 13 and 15 are additionally rejected under 35 U.S.C. 112b or pre-AIA 35 U.S.C. 112 second paragraph as being dependent on a rejected antecedent claim (at least claims 12 and 13 by dependency on 12). 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.
