Specification The disclosure is objected to because of the following informalities: line 1 page 13 recites second portion 114, and line 13 page 16 recites access channel 23 Appropriate correction is required. 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim(s) 1-2, 6, 9, 15 is/are rejected under 35 U.S.C. 103 as being unpatentable over Surbayrole (US-20210136520), in view of, Ramirez (US-11754461), in further view of, Yates (WO-0170422).

Claim(s) 26-29 is/are rejected under 35 U.S.C. 103 as being unpatentable over Surbayrole (US-20210136520), in view of, Ramirez (US-11754461). Surbayrole teaches: In regards to claim 26, Surbayrole teaches a method comprising: receiving a first set of geolocation data from a device in a pipeline; (fig(s) 1-2, 5,abstract, ‘teaches the concept where an object or objects calculates a piece of geolocation information of its own position using a GPS system’; para [0046]) receiving a second set of geolocation data from the device in the pipeline; (fig(s) 1-2, 5,abstract, ‘teaches the concept where an object or objects calculates a piece of geolocation information of its own position using a GPS system’; para [0046]) determining if the device is static in the pipeline based on at least the first set of geolocation data and the second set of geolocation data; and (para [0046], ‘can determine if the object is static’; para [0073], ‘determines if the object is moving’) in response to determining the device is static, determining static coordinates of the device based on at least the second set of data. (abstract, ‘the connected object calculates a piece of geolocation information of its own position based on a plurality of location data coming from various located terminals 2(.1-.5)-terminals’; para [0046], ‘recites computers, radio technology, Wifi’) It would have been obvious before the effective filing date of the invention for Surbayrole to provide a method for a locator device system for geolocation of an object or objects and the like. Surbayrole does not teach: a pipeline Ramirez teaches: a pipeline (abstract; 1, 1’, 15 fig. 6, ‘pipeline’) It would have been obvious before the effective filing date of the invention for Ramiriez to provide a structure as recited above for use in a pipeline for a sensor system and employ the method for a locator device system for geolocation of an object or objects and the like. In regards to claim 27, Surbayrole & Ramirez teach a method according to claim 26, (see claim rejection 26) Surbayrole teaches wherein the coordinates contain a longitude and a latitude. (Surbayrole: fig(s) 1-2, 5,abstract, ‘teaches the concept where an object or objects calculates a piece of geolocation information of its own position using a GPS system’; para [0046]) In regards to claim 28, Surbayrole & Ramirez teach a method according to claim 26, (see claim rejection 26) Surbayrole teaches further comprising generating an alert on a display of the computer sub-system or connected to the computer sub-system, wherein the alert displays the static coordinates of the device in the pipeline. (Surbayrole: abstract, ‘the connected object calculates a piece of geolocation information of its own position based on a plurality of location data coming from various located terminals 2(.1-.5)-terminals’; para [0046], ‘recites computers, radio technology, Wifi’) In regards to claim 29, Surbayrole & Ramirez teach a method according to claim 26, (see claim rejection 26) further comprising: prior to receiving the first set of data, receiving measurement parameter of a pipeline, wherein the parameter is at least one of: (Surbayrole: fig 5; abstract, ‘the connected object calculates a piece of geolocation information of its own position based on a plurality of location data coming from various located terminals 2(.1-.5)-terminals’; para [0046], ‘recites computers, radio technology, Wifi’) a pipeline pressure and a flow rate of fluid in the pipeline; and determining that the parameter suggests scale formation in a portion of the pipeline. (Ramirez: abstract, ‘anomalies or leaks can be detected’; 10-19 col. 7) Allowable Subject Matter Claim(s) 10-14, 16-17 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. Claim(s) 18-25, 30 allowed. None of the reference search suggest the method as recited by claim(s) 10, 18 that protrusions are utilized by a sensor or pigging mechanism for fastening to a scale deposit in a pipeline by a body of a protrusion of a device moving within the pipeline; and claim 30 having a tip at a second end of the protrusion, wherein the body is configured to fasten the device to a scale deposit. Upon completion of a Similarity Search and a PE2E search the closest reference found for scale detection was GB-2402738, however it was for scale deposits in a oil reservoir. The reference US 2,835,548 yields a satellite structure with hemispherical section 10 and 11, a comprising antenna 31 protruding from the sphere however the technology is unrelated and the function of the protrusions are different. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. The references cited Paulson (WO 2006/081671), Yates (WO- 0170422), van Pol (US-11406035), van Pol (US-12146971) and Mcewan (WO- 0186191) references further describe a locator device as described by the claims.
