Grant of rights for Search address technology

From: http://www.ietf.org/ietf-ftp/IPR/hp-mib

Purpose

  This grant is made to help facilitate inclusion of certain patented
  search address technology covering network device mapping in IETF
  standards-track Management Information Base (MIB) modules.  HP is
  offering this search address technology to the IETF as a technique
  for mapping network devices.  It should be noted that the
  confirmatory license mentioned is optional, since the grant of rights
  is automatic.

A Grant of Rights to Hewlett-Packard US Patents 5,293,635 and 5,421,024

  HP hereby covenants that it will not assert any claims in US Patents
  5,293,635, 5,421,024, any continuations, divisions, or
  continuations-in-part of either, or any non-US counterparts of any of
  the foregoing against any party that makes, uses, sells, imports, or
  offers for sale, an implementation of an IETF standards-track MIB
  module that includes HP's contributed search address technology, or
  any derivative of that contribution, provided that the MIB module is
  employed to implement the Internet-standard network management
  framework.  Such grant of rights is limited in that it does not
  include a right to incorporate such HP search address technology into
  proprietary MIB modules.

  This grant of rights will permanently terminate with respect to any
  party (and to any subsidiary of a party) that asserts a patent it
  owns or controls, either directly or indirectly, against HP or any of
  its subsidiaries for implementation of, or operation of any system
  utilizing, search address technology.  The termination of rights will
  occur as of the date the patent is asserted against HP.

  A written confirmation of this grant, and/or a license under any
  other HP patent under HP's then-current terms, conditions, and
  royalty rates, can be obtained by sending a request to:
