DC Comics, the company behind some of our most beloved superheroes, has built a reputation for itself for playing the supervillain when it comes to intellectual property disputes. Chiefly at issue tends to be trademark law, which DC views as some kind of overarching right for it to not allow any other entity to hold a trademark that even remotely overlaps with its own established marks. DC has taken this to absurd levels, opposing trademark applications that couldn't possibly be confused with its own properties, even as many of its marks are very, very well known.

This continues to the present. Most recently, DC has decided to oppose the trademark application for a group founded by MIT's Joy Buolamwini to spotlight the negative consequences of certain technologies, which she dubbed The Algorithmic Justice League.
