One of ordinary skill in the art would have been motivated to make this modification in order to offering the lowest cost-per-part for high volumes, requires minimal post-processing, and produces identical parts with high precision and strength. Claim 9 rejected under 35 U.S.C. 103 as being unpatentable over Levine, US10520133B1 in view of Volckens, US 11474005 B2 and Cox , US20120282019A1. Claim 9 Levine in view of Volckens teaches the apparatus of claim 1 wherein the inlet 20 is an orifice that is designed to prevent obstructions from entering the sampling tube (e.g., col.4 l.34-40) but does not specifically cite it is chamfered and sized according to results of a calculation program used to validate design and performance of a particle detection system. But first In the similar field of endeavor, Cox teaches using chamfered inlet (72)4, and It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to use Cox‘s chamfered inlet for the modified Levine‘s inlet. One of ordinary skill in the art would have been motivated to make this modification in order to facilitates the insertion of the raised end within the inner cavity of the tubular body (Cox ¶0036). Secondly this is an apparatus and based on MPEP2113: For a PBP claim to be valid and distinct from prior art, the process limitation must impart a unique, structural characteristic to the final product. Simply stating the intended use or a standard process isn't enough if the prior art product has the same structure.). third, it is a common practice to size different dimension in a device according to results of a calculation program used to validate design and performance of a system and based on MPEP 2143 (C), courts have ruled that Use of known technique to improve similar devices (methods, or products) in the same way is within the purview of a skilled artisan. See KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398, 415-421,82 USPQ2d 1385, 1395-97 (2007). Claim 12 Levine in view of Volckens teaches the apparatus of claim 1 wherein the inlet is a chamfered hole. and It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to use Cox‘s chamfered inlet for the modified Levine‘s inlet. One of ordinary skill in the art would have been motivated to make this modification in order to facilitates the insertion of the raised end within the inner cavity of the tubular body (Cox ¶0036). Claim 10 rejected under 35 U.S.C. 103 as being unpatentable over Levine, US10520133B1 in view of Volckens, US 11474005 B2 and Taylor, US 20180344963 A1. Claim 10 Levine in view of Volckens teaches the apparatus of claim 1, but does not specifically teach wherein the housing has tabs that mechanically couple to receptacles on the mounting retainer allowing the housing to twist lock in place, but using tabs to allowing a part to twist lock it in place is a well-known technique, for example In the similar field of endeavor, Taylor teaches the fitting 510 has tabs 530 that mechanically couple to chassis portion on the assembly 101 allowing the fitting 510 to twist lock in place (e.g., ¶0041). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to use Taylor‘s twist clocking mechanism for the modified Levine‘s housing that the modified Levine’s tabs mechanically couple to receptacles on the modified Levine‘s mounting retainer allowing the modified Levine‘s housing to twist lock in place. One of ordinary skill in the art know such mechanism and would have been motivated to make this modification in order to provide a highly secure, vibration-resistant, and tamper-proof connection across various industries.
