You are the Real Victim of Piracy

Anyone illegally using CoStar services to compete against you can cost you deals, reduce CoStar’s ability to enhance services and potentially increase CoStar’s subscription fee.

In civil cases, infringers can be liable for CoStar’s lost profits, the infringer’s profits, or statutory damages of up to $150,000 per work infringed (plus CoStar’s attorney fees). In addition, certain types of piracy can be criminally prosecuted. Play it safe. Don’t risk piracy’s costly and embarrassing consequences.
