Drawings 06-22-03 AIA The drawings are objected to as failing to comply with 37 CFR 1.84(p)(4) because reference character “ 160 ” has been used to designate both “relays” and “communication lines” . Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office Action. The objection to the drawings will not be held in abeyance. Claim Rejections - 35 USC § 102 07-06 AIA 15-10-15 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. 07-07-aia AIA 07-07 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 – 07-08-aia AIA (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. 07-15 AIA Claim s 9, 11 and 13 are rejected under 35 U.S.C. 102( a)(1 ) as being anticipated by Jouper US10054646 . Regarding claim 9 , Jouper discloses a method (system-100 implements the method) of signal and power distribution to channels of a testing system for operating one or more hydraulic actuators to apply loads (loads-102) to a test article, comprising: providing power to the channels of the testing system with a pair of power supplies (power supply-103 and 104) connected to load share power (power source-101) provided to the testing system; monitoring the power supplies for proper operation (Col 2 line 8-39); and providing a signal indicative of operation of a power supply of the pair of power supplies outside of proper operation when detected. (Col 2 line 49-67) Regarding claim 11 , Jouper discloses a working power supply of the pair of power supplies assuming the shared load in the event of failure of an other of the pair of power supplies.
