EFF recently wrote about a startup called DITTO that sells eyewear online using a technology it developed to let people see how the glasses would look on them using a webcam. DITTO is being sued by 1-800-CONTACTS for patent infringement. It has also been sued by a Patent Assertion Entity. A narrower term for trolls that focuses on the core business model rather than whether the entity is actually making use of the patented technology ("working the patent"). in the Eastern District of Texas.
To raise money to fight the suits, DITTO is selling some nice t-shirts that say “I Beat Trolls” over at Indiegogo.
I encourage you to help them out. It’s a good cause, and they’re cool shirts:
