Document background
An Infringement Letter is a crucial legal instrument in Swiss intellectual property law enforcement, serving as a formal notification and demand document. This type of communication is typically used when there is evidence of unauthorized use or infringement of intellectual property rights, including patents, trademarks, copyrights, or design rights. The letter must comply with Swiss federal legislation and follows specific requirements regarding content and format. The document should clearly establish the rights holder's position, detail the infringement with supporting evidence, and set forth specific demands with reasonable deadlines. While an Infringement Letter is often the first step in formal enforcement actions, it can also serve as important evidence in subsequent legal proceedings if the matter escalates to litigation.
