This is the fifth installment in our series of FishFAQ videos directed towards Trademarks. This video covers the functionality doctrine.
Patents are meant to cover functional features while trademarks are meant to cover source-identifying features. This video explains the differences and why.
This series is an extension of our initial Patent FishFAQ series.
If videos aren’t your thing, we also have extensive text Patent and Trademark FAQ sections.
and though no videos have been made for Copyright questions, there is a text Copyright FAQ page too
