Dear Web Payments Working Group,

Today Visa joined the Web Payments Working Group and carried out some actions consistent with the W3C Patent Policy [1]: they disclosed some patents and excluded some claims from the Royalty-Free licensing requirement of the W3C Patent Policy for deliverables of this Working Group. As the W3C Patent Policy states [2]:

 "In the event a patent has been disclosed that may be essential, but is not available under W3C RF licensing requirements,  
  a Patent Advisory Group (PAG) will be launched to resolve the conflict.”

For documentation of the procedure that W3C staff follows to launch and operate a PAG, see:

I expect to discuss this within the staff starting next week.

Some questions and answers:

  Q. Can the Working Group continue to work?
  A. Yes. The Patent Policy says: "During the time that the PAG is operating, the Working Group may continue its technical work within the bounds of its charter.”

  Q. Can the Working Group discuss the disclosed patents?
  A. No. The Working Group should focus on technical work. Any discussion of patents should be limited to the PAG.

IMPORTANT: Please, therefore, do not use this mailing list to express opinions about the disclosures.

For the list of disclosed patents and excluded claims, see:

Thank you,
