Office Action

§102 §103 §112
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 . Drawings The drawings are objected to because: None of the recited limitations have reference numerals in the specification. None of the figures illustrated have any reference numerals. The drawings are objected to under 37 CFR 1.83(a). The drawings must show every feature of the invention specified in the claims. Therefore, the manner/mechanism in which “the triangular supports are pivotally attached to the curved metal support” claims 4, 9 and 14 must be shown or the feature(s) canceled from the claim(s). No new matter should be entered. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). 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 Objections Claims 1-3, 6-8 and 11-13 are objected to because of the following informalities: Claims 1, 6 and 11 recite the limitation “a distally attached curved metal support”; keeping in mind that the ladder is part of the ladder stabilizer, what is the term “distally” referring to. In other words which element is it distal from? Claims 2, 7 and 12 recite “the high friction coefficient surface is affixed to the triangular supports”; since claim 1, 6 and 11 from which claims 2, 7 and 12 depend from respectively, establishes only one high friction coefficient surface, are claims 2, 7 and 12 requiring that the one single high friction coefficient surface is affixed to both triangular supports? Claims 3, 8 and 13 recite “rubber, silicone, or other substance”; it appears that the disclosure only has support for rubber, silicone or a layer of asphalt, hence the term “other substance” is too broad to include materials which are not disclosed/described/supported. 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. Claims 6-15 are 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. Claim 6 recites “A method of manufacturing a ladder stabilizer comprising …”; the claim is indefinite because while the claim is directed to a method of manufacturing, it does not recite any method step. It appears that the claim only contains limitations of the ladder stabilizer, while the claim is a method claim. Applicant is reminded that amendment to the claim cannot include new matter and that there is no method steps disclosed in the specification. The same issue re-occurs and applies to claim 11 which recites “A method of using a ladder stabilizer comprising …”. Dependent claims are rejected at least for depending from a rejected claim. 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 Rejections - 35 USC § 103 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 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. Claims 5, 10 and 15 is rejected under 35 U.S.C. 103 as being unpatentable over Johnson as applied to claims 1, 6 and 11 respectively above. In regards to claims 5, 10 and 15 Johnson does not disclose the triangular supports are 6 to 8 inches in width. However, it would have been an obvious matter of design choice to modify the structure of the triangular supports to be 6 to 8 inches in width since such a modification would have involved a mere change in the size of the supports. A change in size is generally recognized as being within the level of ordinary skill in the art. In re Rose, 105 USPQ 237 (CCPA 1955). A person of ordinary skill in the art, before the effective filing date of the claimed invention would have found it obvious to modify the triangular supports to be 6 to 8 inches in width to provide for enough surface area contact between the supports and the surface against which the supports rests to ensure/enhance grip and overall safety and prevent/minimize chances of slippage. Claims 5, 10 and 15 is rejected under 35 U.S.C. 103 as being unpatentable over Andrews as applied to claims 1, 6 and 11 respectively above. In regards to claims 5, 10 and 15 Andrews does not disclose the triangular supports are 6 to 8 inches in width. However, it would have been an obvious matter of design choice to modify the structure of the triangular supports to be 6 to 8 inches in width since such a modification would have involved a mere change in the size of the supports. A change in size is generally recognized as being within the level of ordinary skill in the art. In re Rose, 105 USPQ 237 (CCPA 1955). A person of ordinary skill in the art, before the effective filing date of the claimed invention would have found it obvious to modify the triangular supports to be 6 to 8 inches in width to provide for enough surface area contact between the supports and the surface against which the supports rests to ensure/enhance grip and overall safety and prevent/minimize chances of slippage.
