Under what conditions may the holder of standard-essential patents (SEPs) seek to enjoin an infringing implementer without breaching the SEP holder’s contract with the standard-setting organization (SSO) to provide access to those SEPs on fair, reasonable, and nondiscriminatory (FRAND) terms? I show that the SEP holder’s contractual obligations still permit it to seek an injunction. A FRAND commitment requires the SEP holder to offer a license for the SEPs on FRAND terms (or otherwise to grant implementers access to the SEPs). Extending an offer containing a price within the FRAND range discharges the SEP holder’s contractual obligation. Thereafter, the SEP holder may seek to enjoin an implementer that has rejected a FRAND offer. This analysis indicates the imprudence of categorically banning injunctions for the infringement of SEPs, as some scholars have advocated and as one of the world’s most significant SSOs—the Institute of Electrical and Electronics Engineers (IEEE)—had proposed, as of January 2015, in draft amendments to its bylaws. Such a ban would invite opportunism by implementers and is unnecessary. Courts already can prevent opportunism by SEP holders by conditioning an injunction on the implementer’s actual or constructive rejection of a FRAND offer.
