Term Definition

An Inter Partes Review (IPR) is a trial proceeding conducted at the PTAB, in which a party contests that an issued patent is invalid on a ground raised under §102 or §103 on the basis of prior art consisting of patents or printed publications. The timing limitation for requesting an IPR is 1 year from the date the requester is served with an infringement complaint.


An Intent-to-Use (ITU) application is a trademark application filed to the USPTO based on a good faith "bona fide intention to use your mark" in commerce with your goods and/or services "in the near future". An advantage of pursuing an ITU application before you're actually ready to use your mark in commerce is to create an early filing date, which may be important in the event a legal conflict develops, and could provide your mark priority over another party.
