Office Action

§102 §Other
DETAILED ACTION 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 § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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. Claim(s) 1-8 is/are rejected under 35 U.S.C. 102a1/a2 as being anticipated by Nakanishi et al. (US 2004/0149663 A1). Regarding claim 1, Nakanishi teaches: 1. A water quality measurement device (Abstract+), comprising: a dilution device (e.g., P3, 14); and a residual chlorine concentration measurement device (e.g., 26), wherein the dilution device comprises: a container (e.g., 2); a first liquid level detection portion (e.g., W1); a second liquid level detection portion (e.g., W2); a raw water injection portion (e.g., P1); and a dilution water injection portion (e.g., P2). With regard to limitations in claims 1-8 (e.g., [...] preparing sample water including raw water and dilution water; [...] measuring a residual chlorine concentration of the sample water, [...] detecting a first liquid level in the container; [...] detecting a second liquid level in the container; [...] injecting the raw water into the container until the first liquid level detection portion detects the first liquid level; [...] diluting the raw water by injecting the dilution water into the container until the second liquid level detection portion detects the second liquid level, etc.), these claim limitations are considered process or intended use limitations, which do not further delineate the structure of the claimed apparatus from that of the prior art. Since these claims are drawn to an apparatus statutory class of invention, it is the structural limitations of the apparatus, as recited in the claims, which are considered in determining the patentability of the apparatus itself. These recited process or intended use limitations are accorded no patentable weight to an apparatus. Process limitations do not add patentability to a structure, which is not distinguished from the prior art. A recitation of the intended use of the claimed invention must result in a structural difference between the claimed invention and the prior art in order to patentably distinguish the claimed invention from the prior art. If the prior art structure is capable of performing the intended use, then it meets the claim. See In re Casey, 152 USPQ 235 (CCPA 1967); and In re Otto, 136 USPQ 458, 459 (CCPA 1963). The Courts have held that it is well settled that the recitation of a new intended use, for an old product, does not make a claim to that old product patentable. See In re Schreiber, 128 F.3d 1473, 1477, 44 USPQ2d 1429, 1431 (Fed. Cir. 1997). The Courts have held that the manner of operating an apparatus does not differentiate an apparatus claim from the prior art, if the prior art apparatus teaches all of the structural limitations of the claim. See Ex Parte Masham, 2 USPQ2d 1647 (BPAI 1987) (see MPEP § 2114). Regarding claims 2, 4, Nakanishi teaches: 2. The water quality measurement device according to claim 1, wherein the dilution device comprises: a discharge portion (e.g., 11a). 4. The water quality measurement device according to claim 1, wherein the dilution device comprises a circulation portion (e.g., 22).
