The court said Monday it won't disturb a ruling by the federal appeals court in New York that the rights belong to Penguin Group Inc., and the heirs of John Steinbeck's widow, Elaine. Author John Steinbeck died in 1968; his wife in 2003. The heirs include her sister, four children and grandchildren.

The 2nd U.S. Circuit Court of Appeals said a lower court judge misapplied copyright law in awarding the rights in 2006 to the son, Thomas Steinbeck, and granddaughter Blake Smyle. Both already receive a portion of the proceeds of sales.
