Patents Issued the Week of March 25-29


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. 11,942,878 entitled “Microstructured Field Effect Device” issued March 29, 2024 to BVW Holding AG of Cham, China. Invented by Lukas Bluecher of Eurasburg, Germany and Michael Milbocker of Holliston, Massachusetts. Abstract: A microstructured device is disclosed utilizing Coulomb field modification of surface energy and electroadhesion to localize a device surface or to levitate a device surface with respect to a target surface. The surface energy modification can be permanent or reversible depending on whether the charge is externally delivered to the device or derived on the device galvanically. The microstructure aspect of the device induces various hydrophilic/hydrophobic interactions with the target surface. The Coulomb field can be used to enhance or decrease the hydrophilic/hydrophobic interactions. In combination, the disclosed electro-microstructured device provides for localizing implants in a mammalian body, and additionally means for controlling cell interaction with the implant.
