SAN FRANCISCO — A federal judge has tossed an antitrust class action accusing Apple Inc. of illegally driving up the price of applications sold for use on its signature iPhone.

Represented by Wolf Haldenstein Adler Freeman & Herz, a would-be class of consumers claimed that Apple corners the market for iPhone apps and thus enjoys monopoly pricing. Apple charges developers a 30 percent fee for the apps they sell, forcing consumers to fork over much more than they would in a free market, the plaintiffs alleged.
