Perspective

• AES-OCB has Intellectual Property (IP) claimed by three parties

• Phillip Rogaway

• Virgil Gligor

• IBM (J. Rao)

• All parties have indicated acceptance of standard IEEE guidelines for fair, reasonable, and non-discriminatory licensing terms– IBM sent letter to IEEE 802.11 on Jan. 23, 2002

Submission

IBM’s Licensing Practice

• IBM has participated and provided IP to many of today’s standards

• IBM protects its ownership of IP through licensing• In the absence of an IBM “advocate” IBM

initially provides a standard set of terms for IP licensing

• If an IBM product group sees value in promoting the technology then this group can encourage more favorable terms

Submission

Advocate for AES-OCB

• IBM PCD sees the OCB implementation as beneficial to the industry and our own products and is willing to work on behalf of licensee applicants– We (PCD) do not participate in negotiation of terms – this is the

responsibility of IBM’s IP&Licensing group– We will provide introduction and support for those interested in

licensing the technology• A significant number of companies are already covered under existing

cross-licensing agreements

– We have encouraged IP&L to support terms similar to those published elsewhere and have received favorable response

• Suggested fixed, one-time fee for license restricted to this application
