Claim(s) 1-3 and 5 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Jaumann (US 7878465B2, hereinafter referred to as “Jaumann”). Regarding claim 1, Jaumann discloses a tripod head (title of invention: tripod head), comprising: a case (Fig 1, housing 10), wherein the case (10) is movably provided with a first actuating member (Fig 1, rotary knob 41) and a second actuating member (Fig 2, rotary disc 46 with first control cam 50 with actuating portion 52, and a second control cam 51 with an actuating portion 56); a mounting assembly configured to install a photographic equipment (col 5, lines 47-50), wherein the mounting assembly is movably provided on the case (Fig 1 and col 5, lines 47-50, 16, 17 form the receptacle for camera to be attached); a pivot shaft (Fig 1, shaft 15) movably provided inside the case (col 5, lines 46-47: shaft 15 is rotatably mounted in the housing via ball bearings 14) and connected to the mounting assembly (col 5, lines 47-48); a plurality of energy storage components (Fig 1, energy accumulators 20-25) sleeved onto the pivot shaft (col 5, lines 61-63); and a plurality of locking assemblies (Fig 1, levers 30-35) configured to control the plurality of energy storage components (col 6, lines 1-7), wherein the plurality of locking assemblies correspond respectively to the plurality of energy storage components (col 6, lines 11-19), wherein the first actuating member (rotary knob 41) is connected to at least one of the plurality of locking assemblies (col 7, lines 19-48), and the second actuating member is connected to another at least one of the plurality of locking assemblies (col 7, line 69 to col 8 line 37). Regarding claim 2, Jaumann disclose further comprising a locking shaft (Figs 1 and 3, shaft 37) inside the case (Fig 1); wherein the plurality of locking assemblies (Fig 3, 30-35) comprises a plurality of locking members (Fig 3, 31-35) and a plurality of locking springs (Fig 1, springs 39); wherein the plurality of locking members is movably sleeved onto the locking shaft (col 6, lines 2-4); wherein a locking groove (Fig 1, depression 43) is provided on one side of each of the plurality of energy storage components (21-25, col 7 lines 31-32); wherein a first end of each of the plurality of locking members corresponds to the locking groove (Fig 1, depression 43 corresponds to 44 in Fig 3), and the plurality of locking springs (39) are fixedly provided inside the case (Fig 1) and connected to or abutted against a second side of the plurality of locking members (Fig 1, spring 39 abut a side of 34); and wherein the first actuating member (41) is configured to control a second end of a corresponding locking member to compress or release the locking spring (col 7, lines 19-36), and the second actuating member (rotary disc 46) is configured to control a second end of a corresponding locking member (35) to compress or release the locking spring (Fig 3). Regarding claim 3, Jaumann discloses wherein a first actuating zone is provided on the case; wherein the first actuating zone comprises one or more first trigger holes (col. 8, lines 55-60); wherein a first trigger pin (Fig 3, ram 64) is movably provided inside each of the one or more first trigger holes (col 8, lines 55-60, a hole); wherein one or more first locking trigger parts (Fig 2, 55, 56, 59) are configured to compress the first trigger pin (64) are provided on the first actuating member (Fig 2, col 8, lines 59-60); wherein the first actuating member is movably provided on the first actuating zone (Fig 3, rotary knob 41 moves with rotary disc 46 which has a first control cam 50 with actuating portion 52 which rotatably moves in a circumferential one); wherein the one or more first locking trigger parts correspond respectively to one or more first trigger pins (64); and wherein the first trigger pin (64) is connected to or abutted against one side of the corresponding locking member (35) opposite to the locking spring (Fig 3). Regarding claim 5, Jaumann discloses wherein a plurality of first locking trigger parts (Fig 2, 55, 56, 59) are circumferentially arranged in sequence along a diameter of the first actuating member on the first actuating member (Fig 2, 55, 56 and 59 arranged circumferential around rotary disc 46, which is directly on the round shaped rotary knob 41, see Fig 3 also). Allowable subject matter Claim(s) 4, 6-11 is/are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. The following is a statement of reasons for the indication of allowable subject matter: Cited prior art Jaumann fails to read on the following: a plurality of actuating beads circumferentially provided between the first actuating member and the first actuating zone as claimed in claim 4, wherein a counterweight of an energy storage component corresponding to at least one first trigger pin in the first actuating zone is half of a weight of the energy storage component corresponding to other first trigger pins as claimed in claim 6, and wherein the second actuating zone comprises a second trigger hole; wherein a second trigger pin is movably provided inside the second trigger hole; wherein a second locking trigger part is provided on the second actuating member; wherein the second actuating member is movably provided in the second actuating zone; wherein the second locking trigger part corresponds to the second trigger pin; and wherein the second trigger pin is connected to or abutted against one side of the corresponding locking member opposite to the locking spring as claimed in claim 7, and wherein a sliding groove is provided in the second actuating zone; wherein the second trigger hole is provided in the sliding groove; and wherein the second locking trigger part is vertically movably provided in the sliding groove as claimed in claim 8, and wherein a guiding element is arranged on the second actuating zone; wherein a guide hole is provided on the guiding element; wherein the guide hole is connected to the sliding groove; wherein a connecting part is fixed on the second actuating member; wherein the second actuating member is movably provided on the guiding element; and wherein the connecting part passes through the guide hole to be connected to the second locking trigger part located in the sliding groove as claimed in claim 9, and wherein the first actuating member is connected to one of the three parts, the second actuating member is connected to another one of the three parts as claimed in claim 10, and wherein the damping actuating member is rotatably arranged on the case; wherein a plurality of damping plate assemblies are sleeved onto the pivot shaft; wherein an adjusting post is movably provided on the case; wherein a locking protrusion is provided on the adjusting post; wherein the locking protrusion corresponds to all of the plurality of damping plate assemblies; and wherein a damping trigger is connected to the adjusting post to drive the locking protrusion to move as claimed in claim 11. As allowable subject matter has been indicated, applicant's reply must either comply with all formal requirements or specifically traverse each requirement not complied with. See 37 CFR 1.111(b) and MPEP § 707.07(a). Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
