Apple says Samsung patent royalty demands unfair

Apple said Samsung is demanding from the iPhone maker a far higher patent royalty than Apple pays to other companies, at a rate the South Korean company has never sought from any other licensee.

The information was contained in portions of an Apple legal brief freshly unsealed in U.S. court, and provides more detail about each side's negotiating position in the run-up to a high stakes trial set to begin next week. In a separate filing, Samsung contended that its royalty demands are consistent with industry norms. Also, a U.S. magistrate in San Jose, California, ruled that Samsung wrongly let employees delete emails that could have helped Apple pursue its $2.53 billion lawsuit over disputed patents. The magistrate, Judge Paul Grewal, also said that a jury may hold it against the South Korean company.
