Office Action

§103
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application is being examined under the pre-AIA first to invent provisions. Claim Rejections - 35 USC § 103 The following is a quotation of pre-AIA 35 U.S.C. 103(a) which forms the basis for all obviousness rejections set forth in this Office action: (a) A patent may not be obtained though the invention is not identically disclosed or described as set forth in section 102, if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. Patentability shall not be negated by the manner in which the invention was made. Claims 2 and 3 are rejected under pre-AIA 35 U.S.C. 103(a) as being unpatentable over Meckel (US 2005/0087406) in view of Toby (US 6,457,566). In Re claim 2, Meckel discloses a method comprising: surface finishing at least a portion of two parallel surfaces (20a, 20b) of a brake disk (12); applying a first material (first coating layer 28) via energized vapor deposition (figs. 6-8; Abstract; pars. 0033-0039); and applying a second material (second coating layer 30) via energized vapor deposition (figs. 6-8; Abstract; pars. 0033-0039). Meckel fail to teach applying insignia on to a surface of the brake disk. Toby is related to the art of disk brakes. Toby teaches providing a disk brake (100) with insignia (150; fig. 9) as a visual wear indicator (abstract). The wear indicator allows for easy visual inspection of brake rotor condition without the need for measurement tools. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the brake disk of Meckel to include a visual wear indicator, as taught by Toby, to allow for easy visual inspection of brake rotor condition without the need for measurement tools. The examiner notes that the applying the wear indicator and two layers of material encompass the claimed three-dimensional surface texture. In Re claim 3, Toby discloses the use of machining, understood to encompass “carving”. Allowable Subject Matter Claim 1 is allowed. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
