Star Control Intellectual Property
The name "Star Control" is a registered trademark in the United States. It is registered for use with "computer game software, and manuals supplied as a unit therewith."
While Toys For Bob holds the rights to the Star Control games itself, Atari remains the owner of the Star Control trademark. It is because of this that the Open Source release of Star Control II is named The Ur-Quan Masters, which was the subtitle to the original release.
