Is there a copyleft equivalent for trademarks? I'm thinking of starting a project with distinct branding but I want everything to be based in FOSS principles.

You might look at the licensing terms for the "Linux" trademark, for one well-known example. There are both formal sublicense terms that businesses and projects can sign up for if they use "Linux" as part of their own trademark, and also stated terms for the use of the trademark without a formal sublicense.

The FAQ section of the latter page may be especially informative as it also covers some topics like "what is a trademark?"
