Synaptics issues cease-and-desist to open-source DisplayLink driver developer
Key points
- Synaptics issued cease-and-desist to Mike Lothian for Vino driver.
- Vino driver is open-source, clean-room reverse-engineered.
- Synaptics alleges infringement of two DisplayLink patents.
- Company threatened legal action and cost recoupment.
Cease-and-Desist Issued
Synaptics has issued a cease-and-desist order to Mike Lothian, the developer of the open-source Vino driver for DisplayLink hardware. The company claims that Lothian's work infringes on its patents related to DisplayLink technology. This action follows an initial inquiry from Lothian to a Synaptics engineer regarding bugs in July 2026.
Patent Infringement Allegations
Synaptics specifically cites infringement on two patents: GB2484736 (Image generation) and GB2485613 (Display control device). These patents describe methods for sending screen updates over general-purpose networks and hardware for decompressing data. Lothian's Vino driver was developed through clean-room reverse engineering and partly with AI, written in Rust, and does not infringe on existing code copyright.
Escalation and Threats
After Lothian requested details on how his work infringed the patents, Synaptics escalated its response. Andrew Bateman, Assistant General Counsel, stated the company would bill Lothian to "recoup the cost and effort required to create such documentation of your infringing acts." Bateman also asserted that open-sourcing the technology would "eviscerate DisplayLink's competitive advantage."
Publicity Challenge
Synaptics explicitly encouraged Lothian to publicize their response, stating, "We welcome any and all free publicity to let the world (in particular, our competitors and our shar" know about their stance. This suggests a willingness to engage publicly on the matter.
