Patent Statement and Licensing Declaration form:

• Subsidiary option added under Option 1:
  
  “Also mark here ____ if the Patent Holder reserves the right to license on reasonable terms and conditions (but not for free) to applicants who are only willing to license their patent claims, whose use would be required to implement the above ITU-T Recommendation, on reasonable terms and conditions (but not for free).”
• Definition of ‘Free’ and ‘Reciprocity’ added in the statement form:
  
  Free: The word “free” does not mean that the Patent Holder is waiving all of its rights with respect to the essential patent. Rather, “free” refers to the issue of monetary compensation; i.e., that the Patent Holder will not seek any monetary compensation as part of the licensing arrangement (whether such compensation is called a royalty, a one-time licensing fee, etc.). However, while the Patent Holder in this situation is committing to not charging any monetary amount, the Patent Holder is still entitled to require that the implementer of the ITU-T Recommendation sign a license agreement that contains other reasonable terms and conditions such as those relating to governing law, field of use, reciprocity, warranties, etc.
  
  Reciprocity: As used herein, the word “reciprocity” means that the Patent Holder shall only be required to license any prospective licensee if such prospective licensee will commit to license its essential patent(s) or essential patent claim(s) for implementation of the same ITU-T Recommendation for free or under reasonable terms and conditions.
