Apple outlines how it reached nearly £2bn Samsung damages request

Can you really put a price on innovation? Why yes, you absolutely can, according to recent court filings from Apple.

It was recently revealed that Apple wanted $2.5 billion - or £1.6 billion in old money - in damages from Samsung to settle their patent fight. But how did the Cupertino-based company arrive at that number? New documents submitted in the case break it down.

The document, titled "Summary of Apple's Damages Calculations," was prepared by consulting firm Invotex Group and posted online by Cult of Mac. It splits the assessment into Apple's lost profits, Samsung's profits, what Apple considers to be a reasonable royalty, and then the total the US firm feels it is owed.

Depending on the formula followed - what patents are included, for example - Apple's requested damages range from $2.4 billion to almost $2.9 billion - that's between £1.5 billion and £1.85 billion based on today's exchange rate.

More interesting, however, is that the document includes a handy chart that breaks down which Samsung product Apple believes violates which patent or trade dress claim - and how much that should cost Samsung.

The devices that appear to be the most infringing are the original Galaxy S (i9000) and Galaxy S 4G , both of which violate three Apple utility patents, three design patents, and three trade dress claims, according to the company.

Also cited for three violations of Apple's utility patents are the Captivate, Droid Charge, Epic 4G, and certain versions of the Galaxy S II, the Nexus S 4G, and more.

In one of four scenarios, according to Apple, these infringing Samsung devices have resulted in lost Apple profits of about $489 million (£313m). Cupertino suggests "reasonable royalty" rates for several devices, including $2.1 million (£1.35m) for the Exhibit 4G, $2.9 million (£1.85m) for the Galaxy Tab, $4.2 million (£2.68m) for the Intercept, $3.4 million (£2.17m) for the Nexus S 4G, $6.5 million (£4.16m) for the Replenish, and $1.7 million for the Transform (£1.08m). With this formula, Apple would take home a total of $2.75 billion (£1.75bn).

The other three scenarios include different configurations of lost profits and suggested royalties but are within Apple's suggested range for damages.

Week two of the patent trial between Samsung and Apple kicked off yesterday, with more fights about evidence and a late-night courtroom rendezvous.
