Quote - I have been working in industries for a couple of enterprises, and I know they are usually very delicate when it comes to using or copying their brands. Even as an employed collaborator you cannot just copy the logo from somewhere and paste it in your WORD document, instead it is mandatory to use the official company WORD templates... Color precision to the decimal of a red or green component, precise shape of whatever symbold and fonts, and so on. They can sue you from here to Kingdom Come. I just would prefer a legal and clean solution, with an authorization from Smith Micro for use in commercial promo renders, this is why I came up with the question.

I've been working for about 25 years doing marketing for alot of "big" companies.

Yes, when you ask the person responsible of their graphic profile then you realise that you actually can't do nothing using their logotype. (that person usually change, quite often)
Ignore that person!

What I've learned is that as long as you do not show a company's logotype in a way that would disbenefit them, then everything is ok.
Often they're just glad to see their logo somewhere.

Be advised thou: This don't relate to using Apples logotype (they'll sue you) but otherwise it works with most decent companies.
