Office Action

§101
DETAILED ACTIONAcknowledgment is made of applicant’s amendment filed 12/31/25. Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claim Objections Claim 1 is objected to because of the following informality: On line 9, “the correlation matrix” lacks antecedent basis. Appropriate correction is required. Claim Rejections - 35 USC § 101 35 U.S.C. 101 reads as follows: Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title. Claims 1 - 11 are rejected under 35 U.S.C. 101 because the claimed invention is directed to a judicial exception (i.e., a law of nature, a natural phenomenon, or an abstract idea) without significantly more. Claim 1 is directed to the abstract idea of receiving strain measurements froma network of optical sensors, calculating total strain energy using the received strain measurements, detecting a heavy load on a structure, computing a speed of each event of heavy load detection, resampling strain profiles for all events to have a same speed and amplitude, classifying resampled strain profiles of a correlation matrix and determining whether the heavy load results from a superload vehicle or the environmental event based on the classification. The steps of the claims describe the concept of receiving strain measurements using optical sensors, detecting a heavy load on a structure using a module, and calculating total strain energy using the received strain measurements, computing a speed of each event of heavy load detection, resampling strain profiles for all events to have a same speed and amplitude, classifying resampled strain profiles of a correlation matrix and determining whether the heavy load results from a superload vehicle or the environmental event based on the classification using a processor which are considered abstract ideas. The claim limitations are similar to those previously found by the courts to be abstract such as organizing and manipulating information through mathematical correlations in Digitech Image Techs., LLC v. Electronics for Imaging, Inc. 758 F. 3d 1344, 1350, 111 USPQ2d 1717, 1721 (Fed. Cir. 2014) and collecting information, analyzing it, and displaying certain results of the collection and analysis in Electric Power Group, LLC v. Alstom, S.A., 830 F. 3d 1350, 119 USPQ2d 1739 (Fed. Cir. 2016). All of these concepts relate to tracking, organizing or analyzing information. The concepts described in the claims are not meaningfully different than concepts of gathering data found by the courts to be abstract ideas. As such, the descriptions in the claims of receiving, calculating, detecting, computing, resampling, classifying, and determining is an abstract idea. The claims do not include additional elements that are sufficient to amount to significantly more than the judicial exception because the additional elements are generic controller elements claimed to perform their basic functions of receiving, calculating, detecting, computing, resampling, classifying, and determining. The recitation of the controller limitations amounts to mere instructions to implement the abstract idea. Taking the elements both individually and as a combination, the components at each step of the process perform purely generic computer functions. The claims as a whole do not amount to significantly more than the abstract idea itself because they would be routine in any computer implementation. With respect to Digitech, the courts found that claims drawn to organizing and manipulating data through mathematical correlations using a controller was an abstract idea. The present invention relates to calculating total strain energy using received strain measurements. Taking the courts' opinion in Digitech into consideration in view of the claimed subject matter of the instant application, the controller performs generic computer functions routinely used in computer applications. Generic computer components recited as performing generic computer functions that are understood, routine and conventional activities amount to no more than implementing the abstract idea with a computerized system (See Yan et al., 12,352,643, “Traffic Monitoring Using Optical Sensors”). With respect to Electric Power Group, the courts found that claims drawn to collecting data, analyzing data, and displaying certain results of the collection and analysis was an abstract idea. The present invention relates to receiving strain measurements, processing the strain measurements, detecting a heavy load, computing the speed of the heavy loads, and organizing strain profiles to determine heavy load criteria based on the strain profiles. Taking the courts' opinion in Electric Power Group into consideration in view of the claimed subject matter of the instant application, simply outputting the results of an analysis is considered to be abstract. Furthermore, there is no indication that the receiving and determining steps are performed by any specific structure and in view of Electric Power Group is an extension of the abstract idea presented in Digitech. Thus, generic computer components recited as performing generic computer functions that are understood, routine and conventional activities amount to no more than implementing the abstract idea with a computerized system (See Yan et al., 12,352,643, “Traffic Monitoring Using Optical Sensors”). Allowable Subject Matter Claims 12 – 22 are allowed. The following is a statement of reasons for the indication of allowable subject matter: The primary reasons for indicating allowable subject matter is that the prior art does not anticipate or make obvious the provisions of “compute a speed of each event of heavy load detection; resample strain profiles for all events to have a same speed and amplitude; classify resampled strain profiles of the correlation matrix as corresponding to superload vehicles, environmental events, non-superload vehicles, and non- environmental events; and determine whether the heavy load results from a superload vehicle or the environmental event based on the classification” in combination with the other limitations presented in claim 12. Response to Arguments Applicant’s arguments, on Pg. 1, Para. 4, with respect to these claims have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.9. Yan et al. (12,352,643) disclose traffic monitoring using optical sensors. Pan (CN105788251) discloses based on beidou car network truck overload real-time monitoring system and method. Kim (KR20060086134) discloses a method and system for controlling overloaded vehicle.10.
