I meant "get" it in the sense that I can tell when I do or don't need a lawyer, rather than my friends and family who moan about Google for (c)-ing a photo of the sky ("They don't own the sky!") or what trademarks and patents are even for ("How did Apple get a patent on putting the letter 'i' in front of every product name?", to paraphrase).
I'm no expert, but I'm not a n00b either [that said, I think the monkey should own the copyright on their selfie, not the camera owner, but that's opinion not law. :)]
The rest if my examples, well… I don't even know enough to know if they are hard or easy. Which should be a good sign that I don't have the skills to run a business in its own right, so I'm not sure why other people are telling me I'm wrong about not being able to.
Probably not :)
Even copyright law that's "simple" on paper gets sooo hairy so fast in practice - just look at all the FOSS licenses :)
