1-800-CONTACTS did not respond when I emailed for comment. However, the Electronic Frontier Foundation published its own blog post in support of Ditto saying that 1-800-CONTACTS has “a long record of using the courts to bully its competitors.” That prompted a complaint from the company’s lawyer saying that 1-800-CONTACTS is not a patent troll. The EFF writes:
"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. Patent trolls generally want to use the club of litigation to extort licensing fees. But all indications are that 1-800-CONTACTS isn’t interested in a license from Ditto. Rather, it wants to destroy the competition."
