@ Named coward
I think you've kinda missed my point. It's not that they're obligated (or should be forced) to strike a license deal because of something like FRAND obligations. My point was that Nikon has an underlying and slightly perverse incentive (via the law of unintended consequences) to NOT strike a deal because going to court could land them a bigger payout than they'd get from having completed a reasonable negotiation to both sides mutual benefit.
To put it another way - instead of leaving the goose get on and lay the golden eggs they've decided to cut it open; in court.
Unfortunately for us all (El Reg stories + forums passim) the only ones enriched by that kind of strategy is the lawyers.
