The Grand Star Registrar LLC (GSR), was an online-based partnership, which allows individuals to dedicate and "assign" a name to stars within the known constellations. Upon locating the desired star and assigning the chosen name, GSR records the coordinates and places them into a secure anthology to be published in the United States.
The company was registered and founded in San Francisco, California by then partners, Stephen Cheung and Eric S. Woo. GSR was one of the few registrar companies to utilize extensive alternative media for advertisements in addition to its common references to the 2002 Warner Bros. production, A Walk to Remember.
Names designated by GSR were not recognized by the International Astronomical Union (IAU), which has the internationally recognized authority to name and designate newly discovered stars, planets, asteroids, comets, and other heavenly bodies.
On March 7, 2008, GSR was involved in a civil suit against rival company, International Star Registry (ISR). The suit presided in Illinois Northern District Court under claims of trademark infringement (Lanham Act). Grand Star Registrar, LLC was made to cease and desist operations in June 2008 and the suit was settled outside of court in 2009.
