Office Action

§102 §112
Claim Rejections - 35 USC § 112 Claims 1-3 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 1, line last recites the limitation, “the inner diameter portion, the intermediate portion.” It’s meaning is unknown. Regarding claim 3, the phrase "assuming that" renders the claim indefinite because it is unclear whether the limitation(s) following the phrase are part of the claimed invention. See MPEP § 2173.05(d). Claim 3 recites limitations, 0%, 100%, 50% and 90%, but it is not clear what element or feature these percentages are percentages of. Claim Rejections - 35 USC § 102 Claim(s) 1 & 3 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by JP 2009-083813. Paragraphs 0008-0018 and Figs. 1-4 disclose a wheel bearing device comprising every limitation of the claims. Claims 1-3 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Beier, US 4,893,960. At Fig. 1, Beier shows a wheel bearing device comprising: a wheel bearing including an inner member (1. 12) having double row inner raceway surfaces and a flange portion (5) for being attached to a wheel, an outer member (2) having double row outer raceway surfaces, and a plurality of rolling elements (10, 11) disposed between the inner raceway surfaces and the outer raceway surfaces facing each other; and a constant velocity universal joint having an outer joint member (4), the outer joint member and the inner member being coupled so as to be able to transmit torque by meshing face splines (152, 151) respectively provided in the outer joint member and the inner member and applying a tightening force (see also “tensioned” at col. 3, line 52) in an axial direction between both the face splines. Examiner notes that the remaining limitations are product-by-process limitations to which applicant is reminded that “[t]he patentability of a product does not depend on its method of production. If the product in the product-by-process claim is the same as...a product of the prior art, the claim is unpatentable.” In re Thorpe, 777 F.2d 695, 698, 227 USPQ 964, 966 (Fed. Cir. 1985). See also MPEP § 2113. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Each of Hirano and Funahashi discloses a wheel bearing device.
