Bloomberg has a story about New York-based books publisher John T. Colby suing Apple in federal court today over an alleged infringement of their ‘iBooks’ trademark:

Patently Apple pointed in April of 2010 to Apple’s ‘iBooks’ and ‘iBookStore’ trademark applications with the United States Patent & Trademark Office. Back then, Apple asserted a claim of priority for iBooks based on Trinidad and Tobago application number 41872, filed earlier that year, probably in an effort to have their ‘iBooks’ trademark claim granted ahead of any possible lawsuit.
