The long-standing lawsuit by NCR against Palm and Handspring has been dismissed by the US courts.
NCR had alleged it held two patents governing the creation and sale of handheld devices dating back to 1987.
Researchers from NCR had developed devices for handling and transmitting data in a manner similar to that of current handheld devices, NCR claimed in 2001.
The Delaware court yesterday dismissed the suit. NCR had never used the patents to produce such products.
