A small project of a personal enthusiast has been pushed to the brink by a lawyer from a chip giant. Synaptics recently sent an cease-and-desist letter to LoShian, an open-source enthusiast who developed the “Vino” driver, asking him to stop, remove, and destroy the Linux driver that provides open-source support for DisplayLink devices—and he used Claude AI as a helper while writing the code.
The open-source alternative derived from reverse engineering has hurt who’s interests
DisplayLink technology connects external monitors to computers via USB. Although Synaptics provides support for Linux, it bundles closed-source proprietary components. Loxian’s Vino adopts an independent reverse engineering approach; with Claude assistance, it works on the Dell D6000 dock. It was intended to promote this achievement into the Linux kernel. This precisely hits Synaptics’ sensitive nerves: Legal head Andrew Bettman said outright that public implementation methods would help competitors understand its proprietary technology and weaken its advantage.
Patent stick, priced by week
Synaptics accused Vino of infringing two British patents (GB2484736, 2485613). It demanded the removal of code, documentation, and materials submitted to kernel maintainers, and threatened to claim $25,000 if no rectification was made within a set time limit, with an additional $25,000 added every 7 days thereafter. Lothian denied that he was just a individual player and had not violated any rights, and questioned the validity of the two patents—some of the technologies were already public before the applications were filed. Today, the Vino warehouse has become private, and the related documents and responses have been sent to the Linux kernel mailing list, becoming a public case for the open-source community to observe.
