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. D1,079,124 entitled “Hair Roller” issued June 10, 2025 to LE Holdings LLC of Alamo, California. Invented by Mia Kaminski also of Alamo, California. Claims: The ornamental design for a hair roller as shown and described.

U.S. Patent No. 12,325,977 entitled “Active Lubrication Strategy” issued June 10, 2025 to Deere & Company of Moline, Illinois. Invented by Michael A. Holland of Conrad, Iowa; Clayton P. Neumann of Cedar Falls, Iowa and Greg R. Long of Clay City, Indiana. Abstract: A work vehicle includes a plurality of vehicle drivetrain components, a plurality of state sensors and a variable flow conditioning hydraulic fluid source. A control manifold includes a plurality of control valves to control flow of conditioning hydraulic fluid to the plurality of drivetrain components to lubricate and cool the drivetrain components. A controller receives the state signals and is configured to selectively open one or more of the control valves at least in part in response to the one or more of the state signals to provide flow of conditioning hydraulic fluid to lubricate and cool any of the drivetrain components which are in an active operating state and to close one or more of the control valves to reduce or prevent flow of conditioning hydraulic fluid to any of the drivetrain components which are not in an active operating state.

U.S. Patent No. 12,326,161 entitled “Warm-up Oil Management Strategy” issued June 10, 2025 to Deere & Company of Moline, Illinois. Invented by Michael A. Holland of Conrad, Iowa; Clayton P. Neumann of Cedar Falls, Iowa and Greg R. Long of Clay City, Indiana. Abstract: A hydraulic system of a work vehicle includes a recirculation valve which may be closed during a warm-up mode of operation so that conditioning hydraulic fluid from a conditioning hydraulic fluid pump flows through a high pressure relief valve to a conditioning hydraulic fluid reservoir and recirculates from the conditioning hydraulic fluid reservoir back to the conditioning hydraulic fluid pump. Subsequent to the warm-up mode of operation, the recirculation valve may be opened so that conditioning hydraulic fluid from the conditioning hydraulic fluid pump flows through a low pressure relief valve to a main hydraulic fluid reservoir.
