Certicom's claims up to June 25, 1998 are summarized at:

 http://grouper.ieee.org/groups/1363/P1363/letters/Certicom.txt

More documents claiming intellectual property rights on PK crypto, some of
which ECC-related like the one from HP, are referenced at:

 http://grouper.ieee.org/groups/1363/P1363/patents.html

In 1999, Certicom asserted claims related to ECDSA as well; see letter at:

 http://www.ietf.org/ietf/IPR/CERTICOM-ECDSA

and to algorithms described in draft-ietf-ipsec-ike-ecc-groups-01.txt - see:

 http://www.ietf.org/ietf/IPR/CERTICOM-IPSEC-ECC

Both documents are referenced by the IETF Page of Intellectual Property
Rights Notices at:
