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. Claims 6-7 are rejected under 35 U.S.C. 103 as being unpatentable over Weber (U.S. Publication No. 20200256709). Regarding claim 6, Weber teaches all the features of claim 5 as outlined above, Weber is silent about wherein the property identifier is formed by two message bits of each message. It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to make the property identifier formed by two message bits of each message, since it has been held to be within the general skill of a worker in the art to apply a known technique to a known device (method, or product) ready for improvement to yield predictable results is obvious. KSR International Co. v Teleflex Inc., 550 U.S. 398, 82 USPQ2d 1385 (2007). Regarding claim 7, Weber teaches all the features of claim 5 as outlined above, Weber is silent about wherein the property identifier is formed by a first two message bits of each message. It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to make the property identifier formed by a first two message bits of each message, since it has been held to be within the general skill of a worker in the art to apply a known technique to a known device (method, or product) ready for improvement to yield predictable results is obvious. KSR International Co. v Teleflex Inc., 550 U.S. 398, 82 USPQ2d 1385 (2007). Claim 17 is rejected under 35 U.S.C. 103 as being unpatentable over Weber (U.S. Publication No. 20200256709) in view of Ogawa et al. (U.S. Publication No. 20160344429). Regarding claim 17, Weber teaches all the features of claim 15 as outlined above, Weber is silent about wherein the at least one message of the predetermined kind is a temperature message. Ogawa teaches wherein the at least one message of the predetermined kind is a temperature message (Paragraph 36). It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to include a temperature message in Weber’s information because monitoring rotary machine temperature is crucial for preventing costly equipment failures, ensuring product quality, and maximizing energy efficiency.
