Open-source enthusiast Lothian independently reverse-engineered and developed Vino, an open-source Linux driver supporting DisplayLink devices, with the help of Claude AI during development, and originally planned to merge it into the Linux kernel. Chip giant Synaptics sent him a cease-and-desist letter, alleging that the driver infringes two UK patents and demanding that it be taken down and the related code materials destroyed; failure to comply by the deadline would result in a claim of $25,000, with an additional $25,000 for each week of delay thereafter. The Vino repository has now been made private, and the related materials have been submitted to the Linux kernel mailing list, drawing attention from the open-source community. Lothian argues that there is no infringement and questions the validity of the patents.
