==Definition of Litigation Steps==
The following defines key steps in patent litigation as well as components included in each step. They correspond loosely to the order provided in the timeline above.
'''Complaint''': Document filed in a district court claiming patent infringement. The complaint identifies who has allegedly infringed the patent and how. Often very vague (hence the Innovation/Patent Act). Complaint will be served to the defendant after being filed. Defendant will then be summoned.
