Note:

  This RFC is NOT a standard. It is an official public record of a

  conjunction with the Photuris key management protocol.

Purpose

  This Request for Comments records a grant by IBM Corporation to
  permit the conditional free use of one of its patents.  This grant is
  made to help facilitate adoption of the Internet Key Management
  Protocol contribution IBM has offered to the IETF. It should be noted
  that the confirmatory license mentioned is optional.  The grant is
  made in this RFC and parties have it even if they do not request a
  confirmation from IBM.

A Grant of Rights to Use IBM US Patent 5,148,479

  IBM hereby covenants that it will not assert its US Patent 5,148,479
  or its non-US counterparts against any party that implements Photuris
  or any derivative that includes IBM's IKMP contribution, and operates
  in compliance with Photuris or such derivative, when Photuris or such
  derivative is employed in connection with any Internet Protocol.

  This grant of rights will terminate with respect to any party that
  asserts a patent it owns, directly or indirectly, against IBM for
  IBM's implementation of and operation in compliance with Photuris or
  any derivative, as defined above.  The termination will occur as of
  the date the patent is asserted against IBM.
