Claim Rejections - 35 USC § 103 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. 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) 2 is rejected under 35 U.S.C. 103 as being unpatentable over Fries (US 20100258682 A1) in view of Panuski (US 20210055101 A1). In regards to claim 2, Fries teaches the signal communication system of claim 1, wherein the lamp (148), the receiver device (136), and the communication device (106) are Fries does not teach wherein the lamp, the receiver device, and the communication device are configured to be disposed within an outer housing shaped to fit entirely within a recess of the wayside device. Panuski teaches various devices (212, 216, 218) (Fig. 2) configured to be disposed within (para. [0024]) an outer housing (210) shaped to fit entirely within a recess (152) of the wayside device (150). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the signal communication system of Fries to include configuring various devices to be disposed within an outer housing shaped to fit entirely within a recess of the wayside device as taught by Panuski with a reasonable expectation of success for the purpose of reducing the overall size of the device since it has been held that rearranging parts of an invention involves only routine skill in the art. In re Japikse, 181 F.2d 1019, 86 USPQ 70 (CCPA 1950). See MPEP § 2144.04(VI)(C). Claim(s) 5 is rejected under 35 U.S.C. 103 as being unpatentable over Fries (US 20100258682 A1) in view of Xue (CN 110782683 A). In regards to claim 5, Fries teaches the signal communication system of claim 1, wherein the receiver device (136) (Fig. 3) Fries does not teach a location device. Xue teaches a location device (see machine translation, para. [0051]). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the receiver device of Fries to include a location device as taught by Xue with a reasonable expectation of success for the purpose of increasing data collected (see Xue, para. [0051], lines 3-4) Allowable Subject Matter Claims 8 and 16 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: The prior art fails to teach the combination of limitations as recited in claim 8. Fries teaches the signal communication system of claim 1, wherein the receiver device (136) (Fig. 3) is configured to Fries does not teach wherein the receiver device is configured to determine a geographic location based on the timing signals, and the communication device is configured to send the geographic location in the status signal. It would not have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the signal communication system of Fries to include the receiver device is configured to determine a geographic location based on the timing signals, and the communication device is configured to send the geographic location in the status signal. The Examiner finds no obvious reason to modify the signal communication system of Fries to meet the claimed limitation. Thus, claim 8 is non-obvious in view of the prior art of record, however claim 8 is objected to as being dependent upon a rejected base claim. The prior art fails to teach the combination of limitations as recited in claim 16 due to containing similar allowable limitations as claim 8, however claim 16 is objected to as being dependent upon a rejected base claim. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
