Response to Arguments
Applicant’s arguments filed on 05/27/2025 have been fully considered but they are not fully persuasive.
Applicant’s arguments regarding the 101 rejection have been considered and the 101 rejection withdrawn based on the amended claims reciting control of the vehicle.
Applicant’s arguments regarding the 102/103 rejections are mute since they are directed towards newly added matter of validation of the predicted signs based on the predetermined rules being traffic laws, rules or standards.
In response to arguments that are directed towards claims 6, 8, 9 which are not just towards the new matter: In short, Moed already teaches validating a set of predicted signs and modifying the prediction based on rules, the newly cited reference Tamilarasan teaches validating and modifying a predicted speed sign by using standards and rules and laws of the region. Moed also already teaches the modifying of the sign based on rules, so combining the technique used by Tamilarasan or substituting the validation method of Tamilarasan would solve the same problem of validating a sign and is obvious yielding predictable results. same applies to the argument of claim 6, Pronovost teaches the algorithm using all the information indicated by the claim, Moed teaches a different method “fuzzy algorithm” which is considered an equation that is an obvious design choice outputting the same outcome, the fuzzy algorithm can substitute the algorithm of Pronovost yielding predictable results. Regarding claims 8-9, the use of the fuzzy algorithm to predict sign is a principle of the invention of Moed, thus Moed in itself is not altered, Moed is cited to state that fuzzy algorithm is known in the detection of sign, thus it is obvious to try the method of fuzzy algorithm with reasonable expectation of success, fuzzy algorithm is also based on equations which is obvious design choice. The method of Moed is interpreted as fuzzy algorithm, a fuzzy algorithm compares the input to candidates and gives multiple candidates with corresponding confidences for each candidate instead of giving one simple output.
With respect to arguments regarding claim 7, Beaurepaire is not cited to teach the fuzzy algorithm, but to teach machine learning algorithm for the sign detection.
With respect to arguments regarding claim 10, Wagner is not cited to teach the fuzzy algorithm, but to teach transmitting information.
