Weaponizing The Patent System: A Tiny Startup Faces Financial Extinction
1-800 Contacts released a more elaborate statement to the Electronic Frontier Foundation (EFF), which has defended Ditto online: "1-800 Contacts invested significant time and resources to acquire and license the existent patent rights needed to practice its technology. Clearly, Ditto did not do the same."
The EFF was not impressed: "1-800-Contacts says it is not a patent troll. Sure, the company is not a classic patent troll - a shell company that does nothing but buy patents and sue - but it's little better."
