Office Action

§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 . Specification The title of the invention is not descriptive because the Title names describes an invention that does not work “ ‘{ Irreversible}’ Hybrid ascent and/or descent Device” which means the “ Irreversible” would suggest these parts do not move and in the case of a mechanical part it must be able to move. A new title is required that is clearly indicative of the invention to which the claims are directed. 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 there Four abstracts and it is not clear which one the applicants want to select. 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 Rejections - 35 USC § 112 Claims 1-8 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. The following claims are vague, indefinite, awkwardly, confusingly worded and/or lacking proper antecedent basis: “it” is recited in claim 1 line 12 , claim 4, line 2, claim 5, lines 3 & 4, and claim 7, line 5. The limitation must be positively recited with the proper antecedent basis. The limitation is indefinite. Allowable Subject Matter The following is a statement of reasons for the indication of allowable subject matter: The prior art does not discloses nor teach an invention of claim 1 in its entirety and which at least teach and discloses a transmission means goes across a worm screw mechanism with a first nut which moves axially and second nut which is irreversible, a pulley with an elastic means being claimed in combination with at least the other limitations. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. The 892 form discloses prior art being made of record.
