I think they require some 'independent' source of information, like news articles. I'm quite surprised by the comments on this article. McDonald's didn't present their case properly while that should have been easy. Seems the onus is on them, regardless they still have their appeal.

They provided an independent source of information. You say it should have been easy yet nobody has been able to articulate exactly what they should have done. It's not like the lawyers were being lazy; the information they did supply was quite detailed and would have taken substantial effort to collate.

They "show me that you use it" wasn't only for bigmac, it was also for trademarks they did not used but:

> "trademark bullying; registering brand names... which are simply stored away in a war chest to use against future competitors".

That's right, but here we're talking about the trademark for Big Mac. I'm pretty sure they're using that one.
