Another day, another lawsuit. New York publisher John T. Colby filed a lawsuit against Apple in the Manhattan U.S. District Court on Thursday for trademark infringement over its use of the term “iBooks,” reports “Bloomberg” (

In 2006 and 2007, Colby bought the assets of various entities owned by New York publisher Byron Preiss, who had published more than 1,000 hardcover and paperback books under the “ibooks” name starting in September 1999, according to the lawsuit, which was filed in U.S. District Court in Manhattan on Wednesday.

Apple has a trademark on the name “IBOOK” for computers and once sold a personal computer known as the “iBook,” according to the lawsuit. However, Apple never used the term as a designation for electronic books or an application for the delivery of electronic books until it began selling the iPad in April 2010, Colby said in the lawsuit.
