Patent Protection & Registration

Patents grant property rights on new and useful inventions, allowing the patent holder to prevent others from using, making, or selling that invention without permission for a limited time. U.S. patents are permitted by the U.S. Constitution and are designed to promote scientific progress and invention. By allowing inventors to profit from licensing or selling their patent rights, inventors can recoup their research and development costs and benefit financially from their inventing efforts. There are three main types of patents utility, plant, and design. Utility and plant patents can last up to 20 years, while design patents can last up to 15 years. When a patent expires, the patented material enters the public domain, making it free to use by anyone without a license. U.S. patents are issued by the United States Patent and Trademark Office (USPTO)

U.S. Patent No. 12,505,824 entitled “Active Noise Cancelling System and Method for Exterior Noise Reduction” issued December 23, 2025 to Bridgestone Europe NV/SA of Zaventem, Belgium. Invented by Marco Emiliani, Gaetano Fortunato, Vincenzo Ciaravola, Antonio Scarale and Mattia Giustiniano all of Roma, Italy. Abstract: A system for vehicle exterior noise reduction, comprising: means for measuring amplitude and phase of exterior noise, which 5 propagates at least in part in a first direction from at least one exterior noise source of a vehicle, having an acoustic transmission path, wherein the exterior noise propagates at least in part under an underbody of the vehicle; means for calculating an out of phase signal based at least in part on the measured amplitude and phase of the exterior noise; and 10 means for generating an out of phase sound, based at least in part on the calculated out of phase signal, configured to cancel exterior noise; wherein the generated out of wave sound propagates at least in part in the first direction of the acoustic transmission path.
