Office Action

§112
DETAILED ACTION Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 1-20 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. Claims 1, 8 and 15 each put forth a device that detects by a processor, cloud formation via a machine learning model trained on meteorological data. The specification does not provide support for such a device. The specification discloses that cloud formation is detected via a flood prevention program. The disclosure further puts forth that the program may use sensor data, and that this sensor data may be supplemented by machine learning models trained on meteorological data. The disclosure requires sensor data and the operation of the machine learning model, and does not provide disclosure for a device that utilizes the machine learning model alone. As such, the limitations are recitations of new matter. Claims 1, 8, and 15 are rejected under 35 U.S.C. 112(a) or pre-AIA 35 U.S.C. 112, first paragraph, as based on a disclosure which is not enabling. The disclosure does not enable one of ordinary skill in the art to practice the invention without a sensor, which is/are critical or essential to the practice of the invention but not included in the claim(s). See In re Mayhew, 527 F.2d 1229, 188 USPQ 356 (CCPA 1976). The specification discloses that cloud formation is detected via a flood prevention program. The disclosure further puts forth that the program may use sensor data from (a) sensor(s), and that this sensor data may be supplemented by machine learning models trained on meteorological data. The disclosure requires sensor data and makes optional the inclusion of a machine learning model. As such, the sensor is essential to the embodiment that utilizes a machine learning model. The claims fail to put forth a sensor. As such, the claims omit essential subject matter. The remaining claims are rejected due to dependency from rejected claims. The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1-20 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claims 1, 8 and 15 each put forth a device that detects by a processor, cloud formation via a machine learning model trained on meteorological data. However, the specification discloses that cloud formation is detected via a flood prevention program. The disclosure further puts forth that the program may use sensor data, and that this sensor data may be supplemented by machine learning models trained on meteorological data. The disclosure requires sensor data and the operation of the machine learning model. It is unclear how the device is able to detect cloud formation using a machine learning model, without sensor data. As such, the limitations are indefinite. The remaining claims are rejected due to dependency from rejected claims. Response to Arguments Applicant’s arguments with respect to claim(s) 1-20 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
