Supreme Court Decision Allows Resale of Used Ink Cartridges Despite Patent Holder Restriction

by Michelle Hayes

A patent holder that restricts the reuse or resale of its printer ink cartridges can’t invoke patent law against a remanufacturing company that violates the restriction, the U.S. Supreme Court ruled on Tuesday.

The court ruled that Lexmark International’s patent rights are exhausted with its first sale of the cartridges, despite restrictions it tried to impose.
