What's the cost of patent infringement?
To Apple, $2.5 billion (£1.59 billion).
This is according to a filing made Friday by the prosecuting party in the Apple vs. Samsung case, an ongoing trial unfolding in San Jose, Calif.
Apple alleges Samsung ripped off a number of its design and technology patents, confusing consumers and leading to a dilution of the market that affect its sales.
With the trial, Apple's hoping to get some of those profits back.
For U.S. variants of the Galaxy S and Galaxy S2, Apple's seeking damages to their sales of $1.98 billion (£1.26 billion), $1.34 billion (£8.54 million) for the U.S. version of the Galaxy S alone. The rest comes from other "accused devices."
The profit attack goes after models carried by different parteners, such a Sprint's Epic 4G, of which Apple wants $325 million (£2.07 million) of the profits, and AT&T's Captivate, worth $202 million (£1.28 million) in sales to them.
Apple also wants $642 million (£4.09 million) in profits for the Galaxy Sii
Under American patent law, a design patent owner is entitled to the patent infringer's profits, backing Apple's claims to a piece of Samsung's profit pie
Thanks to sales data released by both company's Thursday, Apple's got a good idea how much it can charge.
