According to Acacia statement free sites are not going after free sites
Under our current licensing model, free adult entertainment sites that do not have audio / video content and send traffic to affiliate programs do not need a license from Acacia. Even though these sites are potentially liable as indirect infringers (for sending users to sites that stream audio / video content using our patented process), we are licensing the owners of the affiliate programs for these infringing activities.
Now considering that Free sites are indeed getting these letters, this is sounding more and more like extortion to me.
Rob Berman: If a company contacted me alleging patent infringement, I would contact the company to find out exactly what I am doing to allegedly infringe the patent. Then I would determine if those acts are important to my business and what it would cost to stop the infringing activity.
Sounds like we all need to follow Acacias own advice on this. If we get a letter contact them and request in EXACT details how they think we are violating their patent.
