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. 12,337,628 entitled “Method for the Treatment of Cords for the Reinforcing Layers of Pneumatic Tires” issued June 24, 2025 to Bridgestone Europe NV/SA of Zaventem, Belgium. Invented by Cristiano Pomposini and Giacomo Andreini both of Rome, Italy. Abstract: Method for the treatment of single-filament polyethylene terephthalate cords for the reinforcing layers of a pneumatic tyre comprising (a) an adhesive solution coating step, wherein the single filament cord is immersed in an adhesive solution; (b) a drying step, wherein the cord covered in adhesive resin is held within a drying oven at a temperature of between 12° and 180° C.; and (c) a thermobonding step wherein the cord, proceeding from the drying step, is arranged within an oven at a temperature of between 23° and 260° C. for a period of between 30 and 90 seconds. During the thermobonding step, the single filament cord is subjected to a tension of between 8 and 12 mN/dtex.

U.S. Patent No. 12,336,457 entitled “Auxiliary Pressure Circuit for a Round Baler” issued June 24, 2025 to Deere & Company of Moline, Illinois. Invented by Austin J. Jones of Ottumwa, Iowa. Abstract: An auxiliary pressure source is provided in the baler hydraulic system of a round baler. During a round bale formation operation and/or during a bale wrapping or tying operation hydraulic pressure provided to the tensioning cylinders of the baler may be periodically boosted above that normally permitted by the high pressure relief valve of the baler hydraulic system.

U.S. Patent No. 12,337,563 entitled “Method of Producing a Tire Equipped with an Electronic Device” issued June 24, 2025 to Bridgestone Europe NV/SA of Zaventem, Belgium. Invented by Francesco Iozia of Rome, Italy. Abstract: Production method of a tyre (1) provided with an electronic device (7) and having the steps of: coupling the electronic device (7) to a support (8) provided with at least one at least partially green rubber component (9); forming the green tyre (1) having an innerliner (6); inserting the green tyre (1) into a vulcanization mould (20); subjecting the green tyre (1) which is inside the vulcanization mould (20) to a vulcanization process; extracting the vulcanized tyre (1) from the vulcanization mould (20) at the end of the vulcanization process; and applying the support (8) containing the electronic device (7) on the innerliner (6) of the vulcanized tyre (1) after the tyre (1) has been extracted from the vulcanization mould (20) when a surface temperature of the innerliner (6) deriving from the heating of the vulcanization process is higher than 90° C.

U.S. Patent No. 12,337,565 entitled “Method and System for Applying a Sealing Agent to the Surface of an Internal Cavity of a Pneumatic Tire” issued June 24, 2025 to Bridgestone Europe NV/SA of Zaventem, Belgium. Invented by Roberto Pontone of Rome, Italy and Paolo Straffi both of Rome, Italy. Abstract: A system is provided for applying a sealing agent to an surface of an internal cavity of a pneumatic tire. The system provides for detecting the weight of the pneumatic tire before and after the application of the sealing agent to the surface, calculating the difference between the quantity of sealing agent applied to the surface and a reference quantity of sealing agent; storing the difference within a short-term memory buffer and a long-term memory buffer; determining a short-term compensation factor and a long-term compensation factor and calculating a correction factor using alternatively the short-term compensation factor or else the long-term compensation factor; and using the correction factor to actuate an applicator device during the subsequent step of applying the strip of sealing agent to the surface.
