Patent Exhaustion in Component Sales: New Risks for Manufacturers

The patent exhaustion doctrine establishes that once a product is lawfully sold under a license, the patent holder's control over that product ends. This principle creates new legal risks for component manufacturers in the supply chain, particularly when products are reused, repaired, or integrated post-sale—situations where manufacturers lose patent protection.

Following the Lexmark v. Impression Products case, the U.S. Supreme Court confirmed that patent exhaustion applies not only to domestic sales but to international transactions as well. This ruling constrains manufacturers' ability to assert patent claims over products that are resold or repaired within global supply chains.

Companies are managing this risk by incorporating "restricted license" clauses into contracts or explicitly defining post-sale usage terms. Technologies such as Digital Rights Management (DRM) technically limit usage rights in software and hardware products.

Ultimately, the patent exhaustion doctrine requires a delicate balance between protecting manufacturer rights and maintaining market access. Supply chain managers must work with legal counsel to update contract language and minimize this risk.

Key Takeaways:
- Patent exhaustion terminates patent rights over a sold product.
- The Lexmark v. Impression Products decision expanded international scope.
- Manufacturers manage risk through "restricted license" agreements.
- DRM technologies technically limit usage rights.
- Legal counsel is critical for updating contract language.
