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.

an open and close section (26,25, and/or 32 figs.3,6) configured to open and close the communication port; and
a biasing section (“spring” in figure below, fig.3) that biases the first flexible membrane (36) in a direction of decreasing volume of the upstream chamber, wherein
the open and close section (26,25, and/or 32 figs.3,6) includes
a shaft section (25 figs.3,6) that is provided across the upstream chamber and the downstream chamber and that is configured to move following displacement of the first flexible membrane (36) and the second flexible membrane (35 and/or 27 figs.3,6) and
a valve section (26,and/or 32 figs.3,6) that is connected to the shaft section (25) and that opens and closes the communication port (23).

Regarding claim 3, Hoshina further teaches wherein the shaft section (25 figs.3,6) is inserted into the second flexible membrane (35 and/or 27 figs.3,6), one end of the shaft section (25 figs.3,6) is connected to the first flexible membrane (36), and an other end of the shaft section (25) is connected to the valve section (26,and/or 32 figs.3,6).
Regarding claim 4, Hoshina further teaches wherein the valve section (26,and/or 32 figs.3,6) has a seal section (portion of 27) configured to intimately contact the communication port.
Regarding claim 5, Hoshina further teaches wherein a bending amount of the first flexible membrane (36 fig.3) when the open and close section is in a closed state is smaller than a bending amount of the first flexible membrane when the open and close section is in an open state (figs.6) and
a bending amount of the second flexible membrane (35 and/or 27 figs.3,6) when the open and close section is in the closed state is smaller than a bending amount of the second flexible membrane when the open and close section is in the open state (figs.6).
Regarding claim 6, Hoshina further teaches wherein a pressure receiving area of the second flexible membrane (35 and/or 27 figs.3,6) and a pressure receiving area of the valve section (26, and/or 32 figs.3,6) are the same.
