Types of jurisdictional territory within the international system

• Incorporated national territory, within which all residents are considered American citizens.
   
• Unincorporated national territory. This can include territories in which the residents do not have full rights.
   
• Trust territories or dependencies. These are territories with some of the attributes of a nation-state but not full independence, administered by a nation, perhaps with international sanction.
   
• Occupied territories. These are usually the result of war and conquest, and ruled by martial law imposed by the conqueror.
   
• International commons. Territory not under the jurisdiction of any nation, but open to use by all, subject to treaty restrictions. This includes the high seas beyond coastal territorial limits, Antarctica, and Outer Space.

General personal jurisdiction

A company doing business on the Internet may be sued for any reason in any jurisdiction where it is incorporated or has its center of operations.^[3] A court may also have general jurisdiction over a party if it has systematic and continuous contacts with the state where the suit is being brought.^[4] The strict requirements for general personal jurisdiction, which would apply to all types of claims whether or not related to the specific contacts at issue, make the theory less applicable for most Internet claims where a party is not deemed "present" in a forum for all purposes^.
