{{Main|ECC patents}}

While the RSA patent expired in 2000, there may be patents in force covering certain aspects of ECC technology, including at least one ECC scheme ([[ECMQV]]). However, [[RSA Security|RSA Laboratories]]<ref>{{cite web | author = RSA Laboratories | url = http://www.emc.com/emc-plus/rsa-labs/standards-initiatives/are-elliptic-curve-cryptosystems-patented.htm | title = 6.3.4 Are elliptic curve cryptosystems patented? | archive-url = https://web.archive.org/web/20161101041810/http://www.emc.com/emc-plus/rsa-labs/standards-initiatives/are-elliptic-curve-cryptosystems-patented.htm | archive-date = 2016-11-01}}</ref> and [[Daniel J. Bernstein]]<ref>{{cite web |first=D. J. |last=Bernstein |url=http://cr.yp.to/ecdh/patents.html |title=Irrelevant patents on elliptic-curve cryptography}}</ref> have argued that the [[Federal government of the United States|US government]] elliptic curve digital signature standard (ECDSA; NIST FIPS 186-3) and certain practical ECC-based key exchange schemes (including ECDH) can be implemented without infringing those patents.
