It'd be nice if they mentioned the nature of the patents being contested. The Bloomberg story only mentions that "The patent [...] was issued in 2004 and is titled Liquid Crystal Display having wide viewing angle."
Seems rather generic. I wish they'd explain what it is that Sharp is alleged to have stolen.
It could be that one of Samsung tv infringe and that one is being banned, and one of Sharp is infringing so that one is being banned. So maybe now Samsung and Sharp will allow their use to tech to each other and get said tv unban.
I researched a lot when I was buying my first LCD TV and from an industry report, for the first two years LCD/Plasma was widely available and affordable, SHARP controls 90% of the market because it is the first on the market.
Patents are intentionally filed to be as vague and seemingly inclusive as possible, and somehow they are accepted in such a form. Patent law is probably more screwed up and backwards than Copyright law, it just gets less attention because its harder for millions of people to produce high tech gadgets in their homes than download stuff.
