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 14 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. 11,278,941 entitled “Selective Termination of Superhydrophobic Surfaces” issued March 22, 2022 to BVW Holding AH of Cham, China. Invented by Michael Milbocker of Holliston, Massachusetts and Lukas Bluecher of Eurasburg, Germany. Abstract: Provided herein is a hierarchical superhydrophobic surface comprising an array of first geometrical features disposed on a substrate comprising a first material, and an array of second geometrical features disposed on the first features to form a hierarchical structure and a terminal level disposed on the second features, wherein the terminal level comprises a second material, the second material being different from the first material. The second material has a hydrophilicity different from the hydrophilicity of at least one of 1) the hydrophilicity of the second material and 2) hydrophilicity induced by the hierarchical structure. The present disclosure further methods of preparing hierarchical superhydrophobic surfaces and medical devices comprising the hierarchical superhydrophobic surfaces.
