Office Action

§112
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 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 1-12 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. In claim 1, the limitation “inclined with respect to an axial direction in a radial directional view” is unclear as “a radial directional view” is not an understood view. Is the Applicant referencing a cross sectional through perpendicular to the longitudinal direction or a cross sectional view parallel to the radial direction or is this some other view? In claim 2, the limitation “that is parallel to a surface on a second member side of the bearing plate piece adjacent to the second member” is unclear through the use of “ands” and commas throughout the claim as it creates uncertainty of what “that” is parallel to. Is “that” is referencing the inclined surface or the other surface? What is “that” modifying? Assuming “that” is referencing the other surface, the phrasing should be changed to “the second member has an inclined surface facing the inclined surface of the first member, a fixed surface is provided on a side opposite to the inclined surface of the second member in the circumferential direction, and the fixed surface is parallel to a fixed surface on a second member side of the bearing plate piece adjacent to the second member” or something similar to be clear. In claim 6, the limitation “the second member is provided for each row of the bearing plate pieces” is indefinite because claim 5 brings in a plurality of the second members. Is the applicant attempting to reference a single one of the plurality or should the claim reference “the plurality”? In claim 11, the limitation “the fixing device has a circumferential width that is changeable by moving the second member relative to the first member in the axial direction” is indefinite because claim 5 brings in a plurality of the second members. Is the applicant attempting to reference a single one of the plurality or should the claim reference “the plurality”? In claim 12, the limitation “the fixing device has a circumferential width that is changeable by moving the second member relative to the first member in the axial direction” is indefinite because claim 5, which claim 6 is depended on, brings in a plurality of the second members. Is the applicant attempting to reference a single one of the plurality or should the claim reference “the plurality”? Allowable Subject Matter Claims 1-12 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action. The following is a statement of reasons for the indication of allowable subject matter: the prior art of record does not disclose nor render obvious the combination set forth in claim 1. In particular, as best understood, the prior art of record does not disclose nor render obvious a bearing comprising “the fixing device includes a first member having an inclined surface that is inclined with respect to an axial direction in a radial directional view, and a second member configured for moving along the inclined surface of the first member and pressing the bearing plate pieces” in combination with the other claim limitations. The examiner is assuming the “an axial direction view in a radial directional view” is similar to the view when looking straight at fig. 2. The closest prior art Kawabata, JP 2014092178 A, discloses a slide bearing structure with multiple bearing pieces but they do not disclose the limitation above. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Boyd (US 2372054 A) discloses a bearing assembly but does not disclose the necessary limitations.
