How can a patent that is deemed essential for a standard not be infringed in a product that implements that standard? One possible explanation could be that the claim of essentiality is incorrect. That’s why it is important to document essentiality with a claim chart and ask an independent expert to verify that infringement of the patent claim is prescribed by the standard. But an independent verification is still no guarantee that court will agree that such a patent is really infringed by a product. Another explanation is that the patent is essential for an option in the standard and that the product does not implement this particular option. Most technical specifications of interface standards have options, describing alternative methods to implement the standard. Manufacturers can choose one of the options and will not infringe patents that are essential for implementing another option.

The U.S. Supreme Court’s recent decision in Kimble v. Marvel Entertainment, LLC (2015) rejuvenates a 50-year-old rule that limits collecting patent royalties after a patent expires. On June 22, 2015, the Court upheld its per se Brulotte rule that bars a patent licensor’s collection of royalties for the use of a claimed invention beyond the expiration date of the underlying patent. The Court directly addressed criticisms of this rule, which originated in its Brulotte v. Thys Co. (1964) decision, and foreclosed any speculation about the continued viability of Brulotte’s bright-line rule in current practice.
