Reminded me that Apple had a trademark suit against Woolworths (Woolies) in Australia a few years ago for using a 'fresh fruit' logo that looked a bit like an Apple.

My takeaway from this is that trademark lawyers do their thing because they have to be seen to be protecting their trademarks, and I'm patently sick of the whole Apple legal patent/copyright stories that I'm just going to filter them from now on.
Lawyers be being lawyers.
