Claim Rejections - 35 USC § 103 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. Claim(s) 11 is/are rejected under 35 U.S.C. 103 as being unpatentable over Luukkala in view of Schiff. Regarding Claim 11. Luukkala silent about said detection plate comprises a solar panel. Schiff further teaches said detection plate comprises a solar panel([0041]-[0042]. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to the invention of Luukkala, said detection plate comprises a solar panel, as taught by Schiff, so as to accurate hail detection and other site-specific measurements and parameters in compact and inexpensive way. Claim(s) 17 is/are rejected under 35 U.S.C. 103 as being unpatentable over Luukkala in view of Sutter et al. (US 2016/0265993). Regarding Claim 17. Luukkala silent about said detection plate has an area of at least 3.5 square feet to 100 square feet. However, Sutter teaches said detection plate has an area of at least 3.5 square feet to 100 square feet ([0068], fig. 11). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to the invention of Luukkala, aid detection plate has an area of at least 3.5 square feet to 100 square feet, as taught by Sutter, so as to Hail strike recording device of roof assembly used for building structure. Claim(s) 28, 95 and 99 is/are rejected under 35 U.S.C. 103 as being unpatentable over Luukkala in view of Warude et al. (Harnessing of Kinetic Energy of Raindrops, 2015) Regarding Claim 28. Luukkala teaches an elastic covering component that partially or fully covers the top of the detection plate (covering the detector surface, such as piezoelectric PVDF polymer film:[0050]-[0052], [0073]). Luukkala silent about said elastic covering, i.e. PVDF polymer film, maximizes transfer of impactor kinetic energy to the detection plate. However, Warude teaches said elastic covering, i.e. PVDF polymer film, maximizes transfer of impactor kinetic energy to the detection plate(PVDF material as it best suits the requirement in terms of flexibility, strength, and sensitivity to mechanical strain. The diagram fig 6. Shows the experimental setup for collection of vibration energy. several piezoelectric membranes are used to obtain the impact vibration without loss page 196-198, section 3.2; table 6). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to the invention of Luukkala, PVDF polymer film, maximizes transfer of impactor kinetic energy to the detection plate, as taught by Warude, so as to calculate procurable energy of the raindrops in compact and inexpensive way. Regarding Claim 95. Luukkala further teaches said elastic covering component comprises a rubber, foam, membrane, meshed material, or net PVDF polymer film:[0050]-[0052], [0073]. Regarding Claim 99.

Claim(s) 96-98 is/are rejected under 35 U.S.C. 103 as being unpatentable over Luukkala in view of Warude, further in view of Lomasney (US 2018/0183383). Regarding Claim 96. The modified Luukkal silent about said elastic covering component permits transmission of light. However, Lomasney teaches said elastic covering, i.e. PVDF, component permits transmission of light (The solar absorber may consist of any of the materials that are capable of converting sunlight into electricity. Examples are monocrystalline or amorphous silicon, CIGS, gallium arsenide, and cadmium telluride.The solar absorber is covered with a suitable polymeric covering. Examples of polymers that can be employed for such purpose include fluorinated polymers such as ethylene tetrafluoroethylene copolymer (ETFE), fluorinated ethylene propylene (FEP), and polyvinylidene fluoride (PVDF). Such polymers provide extended lifetimes under ambient exposure conditions. These also exhibit light transmission property : [0100]-[0101]). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to the modified invention of Luukkala, said elastic covering, i.e. PVDF, component permits transmission of light, as taught by Lomasney, so as to manage the excess heat to mitigate an adverse effect on an electrical output of a semiconductor and electronics systems, thus extending operational lifetime of a photovoltaic system and improving energy conversion efficiency. Regarding Claim 97. The modified Luukkal silent about said elastic covering component permits transmission of light sufficient to produce electric current by a photovoltaic panel. However, Lomasney teaches said elastic covering component permits transmission of light sufficient to produce electric current by a photovoltaic panel ((The solar absorber may consist of any of the materials that are capable of converting sunlight into electricity. Examples are monocrystalline or amorphous silicon, CIGS, gallium arsenide, and cadmium telluride.The solar absorber is covered with a suitable polymeric covering.

Such polymers provide extended lifetimes under ambient exposure conditions. These also exhibit light transmission property : [0100]-[0101]) It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to the modified invention of Luukkala, said elastic covering component permits transmission of light sufficient to produce electric current by a photovoltaic panel, as taught by Lomasney, so as to manage the excess heat to mitigate an adverse effect on an electrical output of a semiconductor and electronics systems, thus extending operational lifetime of a photovoltaic system and improving energy conversion efficiency. Regarding Claim 98. Luukkal further teaches a layer of piezoelectric ceramic material ([0052]). The modified Luukkal silent said elastic covering component comprises silicone. However, Lomasney teaches said elastic covering component comprises silicone([0087], [0100]). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to the modified invention of Luukkala, said elastic covering component comprises silicone, as taught by Lomasney, so as to manage the excess heat to mitigate an adverse effect on an electrical output of a semiconductor and electronics systems, thus extending operational lifetime of a photovoltaic system and improving energy conversion efficiency. Response to Argument Applicant’s arguments with respect to claim(s) 1 and 28, applicant argus that cited prior arts does not teaches amended limitation. In response , the Examiner respectfully disagree because cited prior art teaches the amended limitation as wherein said force sensor attaches said detection plate (resilient mounting adapter component Typically, detector 3 is rigidly mounted on the detector surface 2:[0048])to said supporting frame(bottom 8)(The cover 2 is rigidly attached at its edges to the body 5 of the box and in the middle of it a ceramic piezo element 3 is attached to its underside by gluing or soldering with electronics and bolted with bottom 8: [0047]-[0050] , [0055]; figs 2a-2b).
