Office Action

§102
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. Claims 1 and 2 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Shirasawa et al. US PG-PUB 2020/0116541 A1 (hereafter Shirasawa), prior art of record as indicated on the IDS filed 12 January 2024. As to claim 1: Shirasawa discloses a gas meter (1; see fig. 1 and ¶ 19) comprising: a flow rate measuring member (3; see fig. 1 and ¶ 20) configured to measure a flow rate of a gas (see ¶ 21); a storage (9; see fig. 1 and ¶ 23) configured to store a plurality of pieces of predetermined data (see ¶ 23 and 24), except for a meter read value (see ¶ 23 and 24; neither of which discloses the data being a meter read value specifically), of a plurality of pieces of data each of which is calculated based on the flow rate measured by the flow rate measuring member (see ¶ 24); a condition setting member (7; see fig. 1 and ¶ 21) configured to set a type of, and a storage condition for, the predetermined data to be stored in the storage (see ¶ 23 and 24); and a communicator (10; see fig. 1 and ¶ 27) for transmitting (see ¶ 27) the plurality of pieces of predetermined data stored in the storage to an external device (11; see fig. 1 and ¶ 27); the storage starting sequentially storing the plurality of pieces of predetermined data in response to an occurrence of a predetermined event set by the condition setting member (see ¶ 27 as well as ¶ 33 and ¶ 35), the communicator (10) transmitting, at a predetermined timing set by the condition setting member, the plurality of pieces of predetermined data stored in the storage to the external device (see ¶ 27 and 30). As to claim 2: Shirasawa discloses a gas meter (1; see fig. 1 and ¶ 19) comprising: a flow rate measuring member (3; see fig. 1 and ¶ 20) configured to measure a flow rate of a gas (see ¶ 21); a sensor member (12; see fig. 1 and ¶ 30) including a sensor (12) configured to measure at least one of vibration, temperature (see ¶ 30), or pressure; a storage (9; see fig. 1 and ¶ 23) configured to store a plurality of pieces of predetermined data (see ¶ 23 and 24) of a plurality of pieces of data measured by the sensor member (see ¶ 30); a condition setting member (7; see fig. 1 and ¶ 21) configured to set a type of, and a storage condition for, the predetermined data to be stored in the storage (see ¶ 23 and 24); and a communicator (10; see fig. 1 and ¶ 27) configured to transmit (see ¶ 27) the plurality of pieces of predetermined data stored in the storage to an external device (11; see fig. 1 and ¶ 27), the storage starting sequentially storing the plurality of pieces of predetermined data in response to an occurrence of a predetermined event set by the condition setting member (see ¶ 27 as well as ¶ 33 and ¶ 35), the communicator (10) transmitting, at a predetermined timing set by the condition setting member, the plurality of pieces of predetermined data stored in the storage to the external device (see ¶ 27 and 30). References Cited but not Relied Upon As to references cited but not relied upon: Downie US PG-PUB 2013/0340859 A1 discloses a meter for measuring the mass flow rate of a gas and appears pertinent to Applicant’s disclosure.
