Legal Definitions - permissible-repair doctrine

The permissible-repair doctrine is a rule in patent law that allows a licensee who is authorized to produce, use, or distribute a patented device to also have the right to repair and replace unpatented components.

For example, if a company has a license to produce a patented machine, they can also repair and replace any unpatented parts of the machine without infringing on the patent. This allows for the continued use and maintenance of the machine without violating patent laws.

The permissible-repair doctrine is important because it allows for the efficient and cost-effective maintenance of patented devices, while still protecting the rights of the patent holder.
