Time Trax Technologies has submitted an Amicus Curiae brief ("friend of court" brief) to the US Supreme Court along with several emerging technology companies and the Electronic Frontier Foundation (EFF) in support of Grokster. A "friend of the court" brief is simply a legal brief filed to support or oppose a party in litigation. The brief argues that tightening copyright infringement requirements on technology like Grokster will greatly deter growth and competition in the United States.

The Amicus brief submitted to the court was signed by ten companies potentially affected by the ruling and asks the Court to refrain from assigning liability for product use to its manufacturer based on an immeasurable definition of "primary use." A victory for Grokster would open the gates for continued development in this field.

The Supreme Court is hearing the case, Metro-Goldwyn-Mayer v. Grokster, tomorrow (Tuesday, March 29, 2005). So far, two Federal Courts have agreed with Grokster. Grokster has successfully argued that because it operates on a decentralized network, it cannot be held to the same standards as Napster. MGM must convince at least 5 justices of the US Supreme Court that two prior Federal Court decisions were wrong for not finding Grokster libel for copyright infringement.
