Office Action

§102 §103
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 . The information disclosure statements filed on 6/11/2024 and 1/10/2004 have been entered. Claims 1-12 are presented for examination. 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. Claims 1-3, 5-7 and 9-11 are rejected under 35 U.S.C. 102 (a) (2) as being anticipated by CN 207720019 U by Yin et al. (CN 207720019 U by Yin et al.; herein after referred to as “Yin”). Regarding claims 1, 5 and 9, Yin discloses a portable energy system, comprising: a controller configured to control periodic polling to determine when a load is attached or actively connected to the portable energy system, such that when the load is attached to the portable energy system, the controller energizes the portable energy system for supplying power to the load, and when the load is not attached or not actively connected to the portable energy system, the controller deenergizes the portable energy system output for not supplying power to the load (Yin; portable emergency power supply converter having an inverter, a load detector, a main controller and a driver, wherein the main controller comprises a polling pulse signal generator, load detector, detecting pulse signal generator sending polling to drive pulse signal, power supply automatic device after detecting the access according to the load output end directly and independently output the 50 Hz AC 380V three phase power supply or DC 110V). Regarding claims 2, 6 and 10, Yin discloses the portable energy system of claim 1, wherein the load is one of a DC load or an AC load (Yin; portable emergency power supply converter having an inverter, a load detector, a main controller and a driver, wherein the main controller comprises a polling pulse signal generator, load detector, detecting pulse signal generator sending polling to drive pulse signal, power supply automatic device after detecting the access according to the load output end directly and independently output the 50 Hz AC 380V three phase power supply or DC 110V). Regarding claims 3, 7 and 11, Yin discloses the portable energy system of claim 1, wherein the controller is configured to determine when the load is attached to the portable energy system based on at least one of sensing an output to the load or sensing a current draw from the load (Yin; portable emergency power supply converter having an inverter, a load detector, a main controller and a driver, wherein the main controller comprises a polling pulse signal generator, load detector, detecting pulse signal generator sending polling to drive pulse signal, power supply automatic device after detecting the access according to the load output end directly and independently output the 50 Hz AC 380V three phase power supply or DC 110V; load detector is a current sensor). Claim Rejections - 35 USC § 103 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 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claims 4, 8 and 12 are rejected under 35 U.S.C. 103 as being unpatentable over CN 207720019 U by Yin et al. (CN 207720019 U by Yin et al.; herein after referred to as “Yin”) in view of Buragohain (Buragohain – 11,480,529). Regarding claims 4, 8 and 12, see the discussions to claim 1 in view of Yin. The claims differ in calling for the portable energy system of claim 1, wherein the periodic polling is performed 100ms of every 1s or as applicable to the application algorithm needs. However, the claimed polling period is not new. Reference to Buragohain is cited as evidence of the conventionality of the claimed limitation. Specifically, Buragohain discloses the polling period could be set arbitrarily from 20ms to 1000ms (1 sec.) In view of Buragohain’s teachings, it would have been obvious before the effective filing date of the invention to incorporate the specific polling period in the system as taught by Yin. The modification is well within the skilled levels and expectations of an ordinary skilled in the art in view of Buragohain.
