Office Action

§102
DETAILED ACTION The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . A preliminary amendment was filed by applicant on 09/20/2023. Claims 3 and 5 are amended. Claims 1-5 are remaining in the application The amended Abstract and Specification are accepted. Claim Rejections - 35 USC § 102 6. 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. As best understood by the examiner, claims 1-3 and 5 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by D1: JP 2010223113 A (KOBAYASHI OSAMU). D1 discloses the claimed method of claims 1-3 and 5; see D1 Figs. 1-17 and corresponding written description (particularly Figs. 3-5, paras. [0023] - [0026], [0041] - [0044]). Regarding claims 1 and 2, D1 discloses raising a floating body [2] for spar-type offshore wind power generation facility to raise upright the floating body [2] from floating on its side with injecting ballast water at sea by decentering a center of gravity of the floating body by means of a center-of-gravity decentering means (water ballast and/or weights); and injecting ballast water to raise upright the floating body from a sideways position (Fig. 3) to an inclined position (Fig. 4) by stopping injection of ballast water and re-injecting ballast water to raise upright the floating body to a fully upright (vertical) position (Fig. 5). Regarding claims 3 and 5, the center-of-gravity decentering means can be a weight (concrete ring) detachably attached to outer surface of the floating body (on concrete cylindrical body section [12] on top of ballast portion [10]) or solid ballast (concrete block) within the floating body [2]; see para. [0044]. Allowable Subject Matter Claim 4 is objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Conclusion 9. The prior art cited and not relied upon is considered pertinent to applicant’s disclosure. The prior art references cited disclose ballasting of spar type offshore floating bodies/facilities. 10.
