@Gargron I could ask Dr. Michael Stehmann, if this helps. He is a lawyer and active in the legal network of FSFE. I don't know whether he does free software law himself, but I'm sure he could refer you to someone who does.

@stefanieschulte I am worried about bothering such high profile people. Like. This isn't about Java vs Google type stuff. I just need some minor trademark legalese and advice about CLAs

@Gargron I'm not a lawyer myself, but I think a lot of free software related legal stuff is exactly the kind you're describing. And Michael is quite a normal person, as far as I know 😉... He might know who would be the right person for this kind of job (I think).
