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. 12,366,042 entitled “Self-Propelled Construction Machine and Method for Working a Ground Pavement” issued July 22, 2025 to Wirtgen GmbH of Windhagen, Germany. Invented by Christian Berning of Zülpich, Germany; Hanjo Held of Windhagen, Germany and René Müller of Vettelschoss, Germany. Abstract: In a self-propelled construction machine (1), in particular road milling machine or surface miner, for working a ground pavement, comprising a milling drum (10), which is mounted in a machine frame, wherein a milling cut develops during milling of the ground pavement with the milling drum (10), wherein the milling drum (10) comprises a first and a second end side, at least a first measuring device, which is arranged next to the first end side of the milling drum (10) and measures the distance of the machine frame relative to the ground pavement next to the first end side of the milling drum (10), at least a second measuring device, which is arranged next to the second end side of the milling drum (10) and measures the distance of the machine frame relative to the ground pavement next to the second end side of the milling drum (10), and a control device (40) for controlling the milling depth, wherein, in a first milling operation, the control device (40) determines the milling depth by means of measurements performed by the first and the second measuring device, it is provided for the following features to be achieved: a second milling operation is detectable by means of the control device (40), in which the milling drum (10) is positioned on an as yet non-milled milling cut that is arranged next to a previously milled milling cut, wherein the control device (40), as soon as the second milling operation is detected, uses measurements performed by at least a third measuring device in lieu of the first and/or the second measuring device for determining the milling depth.

U.S. Patent No. 12,368,345 entitled “Toroidal Electric Generator” issued July 22, 2025 to Infinity Electric Energy S.r.L. of Milano, Italy. Invented by Ludovico Bonfiglio also of Milano, Italy. Abstract: The invention relates to a toroidal electric generator (100) comprising a stator (20), which includes a tubular body (21) supporting a plurality of windings (24), and a rotor (30) rotatable within the stator (20) and comprising a support element (31) and a plurality of hydraulic blades (32), each provided with a respective magnet (34) and mounted on the support element (31) integral to it. The toroidal electric generator (100) further comprises an external casing (40) and a plurality of separating elements (51, 52), each separating element being arranged between a respective pair of adjacent windings (24) of the plurality of windings (24) of the stator (20).

U.S. Patent No. 12,366,248 entitled “Volumetric Lobe Compressor for an Equipment and/or a Suction Compression Plant of Material in Liquid, Gaseous, Solid, Powder, or Slurry Form” issued July 22, 2025 to Jurop S.p.A. of Azzano Decimo, Italy. Invented by Danilo Santarossa also of Azzano Decimo, Italy. Abstract: The present invention concerns a volumetric compressor (1) that can be used, preferably, for producing equipment and/or a plant for the suction of material in liquid, solid, powder or slurry form. The compressor according to the invention comprises a body (2) defining an operative chamber (5), a suction section (51) and a discharge section (52) of an operating fluid. The compressor further comprises at least two lobe rotors (8A. 8B), the lobes (81A. 81B) of which are housed inside said operative chamber (5), cach rotor (8A. 8B) rotating around a corresponding longitudinal rotation axis (101A. 101B). The compressor comprises a first header (6) and a second header (6′) which delimit on opposite sides the operative chamber (5): cach header comprises a bank (61, 61′) connected to the body (2) and configured to support the rotors (8A, 8B) and a cover (62, 62′) connected to the bank (61, 61′) so as to define an inner volume (65, 65′) comprised between the cover (62, 62′) and the bank (61, 61′) and designed to house, in use, a lubricating bath. According to the invention the compressor comprises a generator unit for generating a forced flow of cooling gas and, for at least one of the headers (6, 6′), the bank (61, 61′) defines a cooling chamber (70, 70′) physically separated from the operative chamber (5) and from the inner volume of lubricant. Said chamber (70, 70′) comprises an inlet (71, 71′) and an outlet (72, 72′) for a cooling gas, where said inlet communicates with the generator unit of the forced flow of said cooling gas.

U.S. Patent No. 12,365,241 entitled “Axial Shifter Assembly for a Transmission” issued July 22, 2025 to Deere & Company of Moline, Illinois. Invented by Mahendra S. Patil of Pune, India; Thomas G. Ore of Cedar Falls, Iowa; Bradley A. Merrill of Dike, Iowa and Roshan Sharma of Jaipur, India. Abstract: An axial shifter assembly for a transmission. The axial shifter assembly includes a gear and a shifting collar arranged co-axially with each other. The shifting collar has at least one axial tooth projecting axially therefrom and is movable axially between an engaged position in which the at least one axial tooth drivingly engages with the gear and a disengaged position in which the at least one axial tooth is disengaged from the gear. The axial shifter assembly also includes a piston disposed at least partially radially inwards of the shifting collar. The shifting collar moves with the piston. The piston is actuatable between a first axial position corresponding to the disengaged position and a second axial position corresponding to the engaged position.
