("Lexmark") alleging infringement of the patents-in-suit. On February 19, 2008, Nuance filed suit in the United States District Court for the Central District of California against Abbyy USA and Lexmark International, Inc.

These patents relate to methods and systems for performing optical character recognition, recognizing documents, and managing documents.

This court also determines that the district court erred by dismissing the case for improper service of process. Because the record calls for further discovery on these jurisdiction questions, this court vacates the dismissal of Abbyy Software and remands. Because Abbyy Production purposefully directed activities at residents of California, because Nuance's claims for patent infringement arise out of those activities, and because the assertion of personal jurisdiction is reasonable and fair, this court reverses the district court's dismissal of Abbyy Production on personal jurisdiction grounds. Nuance appeals the dismissal of Abbyy Production and Abbyy Software. Abbyy Production and Abbyy Software (collectively, "the Abbyy defendants") thereafter filed a motion to dismiss for lack of personal jurisdiction and improper service of process, which was granted by the United States District Court for the Northern District of California without an evidentiary hearing or further discovery. ("Abbyy Software"), a corporation organized under the laws of the Republic of Cyprus. After obtaining discovery from Abbyy USA, Nuance filed an Amended Complaint naming as defendants Abbyy Production LLC ("Abbyy Production"), a corporation organized under the laws of the Russian Federation, and Abbyy Software, Ltd. ("Nuance") filed this patent infringement action against Abbyy USA Software House ("Abbyy USA").
