Actress Gwyneth Paltrow has been slapped with a copyright infringement lawsuit over her lifestyle website.

Health expert Charles Platkin alleges editors at used his Diet Detective copyright without his permission in an article last month (Jul14).

Platkin, who has owned the trademark since 2004, claims he asked bosses at the company to remove the phrase from their website and they did, but responded the use of Diet Detective was protected under their First Amendment rights of free speech.

He is seeking monetary damages and a jury trial and is asking a judge to bar bosses at the company from using his trademark again.
