Office Action

§102
DETAILED ACTION 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. Claims 1-4 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Furukawa 5,246,336. Furukawa discloses, regarding claim 1, a submersible pump assembly (see pump assembly in Fig. 6) which includes a first centrifugal pump 50a having a first vane design to operate in a clockwise direction (relative to point of view) a second centrifugal pump 50b having a second vane design to operate in a counterclockwise direction (relative to point of view – see how the first and second pumps 50a and 50b have opposite vane designs in Fig. 6, as they face different directions and are connected to the same shaft) a submersible induction or permanent magnet motor 1 (see col. 7, line 14) for driving the first and second centrifugal pumps 50a, 50b the first and second centrifugal pumps being connected to a common shaft 14 (clearly shown in Fig. 6); Re claim 2, wherein the first centrifugal pump 50a has a larger flow rate than the second centrifugal pump 50b (this is clear from structure shown in Fig. 6). Furukawa discloses (under an alternate interpretation), regarding claim 1, a submersible pump assembly (see pump assembly in Fig. 6) which includes a first centrifugal pump 50b having a first vane design to operate in a clockwise direction (relative to point of view) a second centrifugal pump 50a having a second vane design to operate in a counterclockwise direction (relative to point of view – see how the first and second pumps 50b and 50a have opposite vane designs in Fig. 6, as they face different directions and are connected to the same shaft) a submersible induction or permanent magnet motor 1 (see col. 7, line 14) for driving the first and second centrifugal pumps 50b, 50a the first and second centrifugal pumps being connected to a common shaft 14 (clearly shown in Fig. 6); Re claim 3, wherein the first centrifugal pump 50b has a smaller flow rate than the second centrifugal pump 50a (this is clear from structure shown in Fig. 6); Re claim 4, wherein the first centrifugal pump 50b has a smaller flow rate than the second centrifugal pump 50a, or a similar flow rate (this is clear from structure shown in Fig. 6, also the term “similar” is substantially broad).
