Marvel and DC Comics co-operate over very few things. Bad feeling since the Quesada/Jemas days put pay to any crossover projects. But one thing they do co-operate over is defending the use of the phrase "super hero" in the title of – well, anything not published by Marvel or DC.
As it stands there are trademarks that both Marvel and DC are working together to challenge for Silicon Super Heroes by David Martini. Jason Brodie for Super Hero Battleground. Andrew Jones for Superhero Ellie. And plenty more.

British businessman Graham Jules was challenged by Marvel and DC over his self-help manual Business Zero to Superhero in 2014.7
That's usually when most people back down. But Jules didn't. He read a book on intellectual property law and challenged Marvel and DC over the claim.

Or even, just take the money when it's offered. It's possibly worth doing just for that.
Here's an interview with him when the case first came up two years ago…
