As I could read recently CxF is officialy published:

The documentation comes with some hints about related patents. Could 
someone, ideally from X-Rite, comment on the implications for open source 
projects. Especially if it will comply with GPL3:
http://opensource.org/licenses/gpl-3.0.html see clause 11 Patents

X-Rite text:
The originator of this document, X-Rite, Inc. (X-Rite), hereby states that 
X-Rite holds one or more patents
and/or patent applications that may be implicated by use of this document 
and/or proposed standard. When
requested, X-Rite will in good faith negotiate to grant a license to any 
such patent or patent application,
under reasonable and non-discriminatory terms and conditions for the term 
of the patent, to any applicant
throughout the world desiring to utilize the license for the purpose of 
implementing the standard.
Particularly, X-Rite identifies the following patents/patent applications:
                            Title                  Serial No.      Filing 
Date Patent      Issue
No.       Date
              System and Method for 10/047,717                    
10/23/2001 N/A          N/A
              Facilitating Specified and
              Supplier Communications
X-Rite will update the foregoing identification to the extent additional 
patents/patent applications are
identified that bear on this document and/or the proposed standard. In 
addition, recipients of the document
are invited to notify X-Rite of any X-Rite patents/patent applications 
that they believe have bearing on this
document and/or the proposed standard.
Notwithstanding anything in this document to the contrary, X-Rite's 
identification of the patent/patent
applications set forth herein does not reflect an opinion that practicing 
the proposed standard would
necessarily infringe X-Rite's patent rights.

Does "negotiate" mean each open source application is required to ask 
X-Rite about a permission?
