Quick Summary of First-To-File Rule

The first-to-file rule is a legal principle that dictates that when two parties bring the same case to two different courts, the court that receives the case first retains jurisdiction. The second court typically halts its proceedings. However, if the first case was filed solely to prevent the other party from filing, it is not permitted. This is known as anticipatory filing and is utilised to determine factors such as the venue for the case.

Full Definition Of First-To-File Rule

The first-to-file rule is a principle in civil procedure that determines which court will handle a lawsuit when two parties file lawsuits on the same issues in different courts with proper jurisdiction. Generally, the court that first acquires jurisdiction will retain the case, while the other court will stay proceedings. However, there is an exception to this rule called anticipatory filing, where a lawsuit is brought in anticipation of the true plaintiff’s lawsuit and is an improper attempt at forum-shopping. In such cases, the court may dismiss the first-filed lawsuit instead of following the first-to-file rule. For instance, if Company A and Company B both file patent infringement lawsuits against each other in different courts, the court where Company A filed first will handle the case, and the court where Company B filed will stay proceedings. However, if Company A filed their lawsuit in anticipation of Company B’s lawsuit and it is an improper attempt at forum-shopping, the court may dismiss Company A’s lawsuit instead of following the first-to-file rule.
