STONINGTON, Conn. — A Connecticut sporting goods distributor has filed a lawsuit against a company featured on the reality TV show “Shark Tank” and funded by investor Mark Cuban.

Mark Ferrara owns Anthem Sports and says that his line of personal enclosures, meant to protect spectators at sporting events, are not infringements on the ones made by Ohio-based Under the Weather.

Ferrara is seeking to bar Under the Weather representatives, including owner Eric Pescovitz, from using social media to criticize Anthem’s products as imitations.

Ferrara said he designed his own version of a personal enclosure after Pescovitz’s enclosures became too expensive to distribute. Ferrara said he worked with a patent attorney to legally create his own version.
