Standard-essential patents (SEPs) are patents whose claimed inventions cover technology that is required to implement a published technical standard. If a product or service adheres to the standard, practicing the claimed invention may be necessary, making the patent essential to compliance. Essentiality is typically identified by the standards organization or by the standard's disclosure and licensing procedures.

Standards organizations such as IEEE, ITU, ETSI, and 3GPP oversee widely used standards in telecommunications, computing, and multimedia. During standard development, participants may disclose potentially essential patents, and owners may designate certain patents as essential. These declarations help manufacturers assess which patents may be required to implement the standard.

SEPs are commonly licensed on RAND terms—reasonable and non-discriminatory—to balance incentives for invention with access to standardized technology. Licenses may be negotiated directly, via cross-licensing, or through patent pools. FRAND commitments are a central feature in many jurisdictions and standard-setting agreements.

Questions around SEPs include establishing essentiality, determining fair royalty terms, and addressing hold-up or hold-out concerns. Legal disputes may address royalty levels, enforcement of FRAND obligations, and injunctive relief. Jurisdictions differ in how they regulate SEP licensing and remedies.

Common SEPs arise in wireless standards (3G/4G/5G), Wi‑Fi and widely used codecs and interfaces (H.264/AVC, DisplayPort). An SEP differs from a non-essential patent; although SEP owners may license non-essential patents, SEPs are tied to standards and their use is not mandatory if the standard is not adopted.
