Office Action

§102 §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 . Claim Objections Claims 1- 2, 4-5, and 10-11 are objected to because of the following informalities: described below. Appropriate correction is required. Claim 1, recites “Apparatus” in line 1, it is suggested by the Examiner the recitation be changed to “An apparatus”, for grammatical clarity. Claim 1, recites “the apparatus comprising: an assembly ” is objected to because it is redundant, as the assembly is the same as the apparatus, and renaming it is unnecessary and confusing. Examiner suggests the recitation be changed to “The apparatus comprises...” for greater clarity. Claim 2 recites “The apparatus of claim 1, wherein the assembly comprises” is objected to because it is redundant, as the assembly is the same as the apparatus. Examiner suggests the recitation be changed to “The apparatus of claim 1, comprises...” and renaming it is unnecessary and confusing. Claim 4, recites “the apparatus comprising: an assembly… ” is objected to because it is redundant, as the assembly is the same as the apparatus, and renaming it is unnecessary and confusing. Examiner suggests the recitation be changed to “The apparatus of claim 1, comprises…” for greater clarity. Claim 5 recites “The apparatus of claim 4, wherein the assembly comprises…” is objected to because it is redundant, as the assembly is the same as the apparatus. Examiner suggests the recitation be changed to “The apparatus of claim 4, comprises...” and renaming it is unnecessary and confusing. Claim 10, recites “the apparatus comprising: a structure…” is objected to because it is redundant, as the structure is the same as the apparatus, and renaming it is unnecessary and confusing. Examiner suggests the recitation be changed to “The apparatus comprises...” for greater clarity. Claim 11 recites “The apparatus of claim 10, wherein the structure comprises” is objected to because it is redundant, as the structure is the same as the apparatus. Examiner suggests the recitation be changed to “The apparatus of claim 10, comprises..” and renaming it is unnecessary and confusing. Drawings 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 welds upon bushing and axle tube (recited by claims 7, 9, 13, 15) are not identified by any reference character or callout in Figs 22c and 22d (note drawings Fig 32.3 and Fig 32.4 dated 09/18/2023 have welds identified) 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 Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. 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. Claims 3-7, 13-15 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. Regarding claims 3, 7 and 13 the recitation of “a mechanism”, “a brake mount”, “a spindle” “a spider plate”, “a hub”, “a wheel”, indefinite because they are “double recitations” having been previously introduced in the claim on which they depend : 1, 4, 10. It is suggested by Examiner that the recitations be changed such that the leading articles “a” for each of the limits be instead “the” for greater clarity ( i.e. “a mechanism” be changed to “the mechanism”, etc.). Regarding claims 13, 14 and 15, the recitation of “a mechanism”, “an axle tube”, “a brake mount”, “a spindle” “a spider plate”, “a rotor”, “a wheel”, are indefinite because they are “double recitations” having been previously introduced in claim 10. It is suggested by Examiner that the recitations be changed such that the leading article “a” be instead “the” for greater clarity.
