The reason it doesn't fail on the first challenge is in the article and it's the same as patent trolls: most of the companies they've gone after can't afford the legal fees, so they simply roll over a lot faster than Philips did. By the time they get to Philips they have years of success getting other companies to, on paper at least, agree with them. Don't know if that strengthens their case in reality, but the fact is Philips sounds the first one to have put up a real fight. It's still a bullshit judicial decision, though.

The argument that they have to do this to defend their trademark also falls apart when you remember why they haven't sued Kohlberg & Co: their trademark was already in use. And by a supplier, no less.
