The U.S. Supreme Court once again has changed the landscape for software infringement litigation. In a decision released last week, the court severely undercut the ability of plaintiffs to seek out courts that have a track record of being "friendly" to the plaintiff's position -- a practice called "forum shopping." The Supreme Court's unanimous ruling compels plaintiffs seeking software infringement remedies to submit their cases only in district courts located where the defendant either resides or conducts a significant amount of business.
