Title: Rene Struik's Statement of IPR relating to draft-ietf-roll-rpl-10 and belonging to Certicom Corporation Date: 07-12-2010 Submitter: Rene Struik 1. Possible patent holder/applicant: Certicom Corp. 2. Contact information for the IETF participant whose personal belief triggered this disclosure: Marinus (Rene) Struik, phone: +1 (416) 466-8084, email: rstruik.ext@gmail.com 3. IETF document or other contribution to which this IPR disclosure relates: draft-ietf-roll-rpl-10 4. Disclosure of patent information, if known (i.e., patents or patent applications required to be disclosed by Section 6 of RFC 3979): A) This disclosure is related to the following granted patents and published pending patent applications: a) US 7,249,259 B1 Hybrid signature scheme Patent issued: July 24, 2007 Informal decription: Pintsov-Vanstone signature scheme Additional notes: Certicom has issued a patent letter of assurance to IEEE-SA related to 802.15.4-2006, but did not indicate specific IPR. Hence, although unclear right now, some of this may be relevant to security-related portions of the rpl draft as well. Furthermore, Certicom Corp. may have filed IPR other than that mentioned above (published or filed, but not published) and may have filed in other jurisdictions as well. This disclosure is based on best effort and does not judge on validity of patent claims (I am no lawyer, after all). Best regards, Rene
