Using IP addresses to identify individuals accused of copyright infringement has become increasingly common in piracy cases, but an attorney trying to obtain information on several Verizon subscribers has found himself running into problems — from Verizon itself. In a letter to a US district court judge, attorney William Dunnegan writes that his firm served subpoenas to the company in connection with a case launched by publisher John Wiley & Sons, Inc. He'd hoped to obtain information about 10 different Verizon customers. The company refused to comply, however, citing no less then seven different objections, including the manner in which the subpoena was served and that the information sought was "neither relevant nor reasonably calculated to lead to the discovery of relevant information and imposes an undue burden on Verizon." A call between the parties is now scheduled for May 14th to discuss the issue, but with a New York magistrate judge recently ruling that IP addresses aren't a viable way to identify who is downloading material on a given internet connection, we can't help but hope this type of broad legal action may be forced to slow in coming years.
