General Information:  

The World Wide Web consortium (W3C) has released a legal analysis 
which finds that platform for privacy preferences (P3P) technology 
does not infringe a patent held by the Intermind Corporation.  

P3P provides Internet users with more control over the use of their 
personal information and means that websites can inform users of 
their privacy practices.  

The technology was developed in an open collaboration with W3C 
members, but its widespread use was threatened when the patent holder 
sought to charge royalties.  

'Given the fundamental importance of privacy protection on the Web, 
and our commitment to open standards, we decided that it was our 
responsibility to provide the community with a thorough analysis of 
the relationship between the patent and P3P,' said Daniel Weitzner, 
technology and society domain leader at W3C responsible for P3P
