Office Action

§102
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 . Election/Restrictions Claims 2-3, 5-6 and 8-14 remain in the application as withdrawn. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claims 1, 4 and 15 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Wang (US 2018/0274265). Wang discloses a press-fit structure and method comprising a body (114) with a pressurizing portion, a material storage space, a restricting portion and a limit stop portion formed as a flat side over a lower part of the body as defined by the pressurizing portion and restricting portion where the flat side extends over the entire lower part. The pressurizing and restricting portions are arc-shaped and on an opposite side from the flat limit stop portion. An object (a) includes a stop portion corresponding to the limit stop portion. The pressure portion is first arranged on a pressurizing portion of the object and then pressurizing the press-fit structure into the object. The object flow into the storage space is a recitation of the intended use which the structure of Wang would be capable of. See MPEP 2111.02. Additionally, Wang teaches to the object flow in another embodiment (Figs. 17 and 18) but it is unclear if the embodiment including the flat side includes the same object flow.
