This much is certain: Gary Friedrich created the Marvel comics character Ghost Rider. Freidrich sued Marvel (and its new owners, Disney) because he claims that he never signed away the rights to his character, and thus the feature film based on the comic was illegal. Freidrich also apparently launched his own, rival line of authorized Ghost Rider merchandise.
Disney/Marvel has countersued Freidrich, claiming that the boilerplate legalese on the back of his paychecks were all the assignment they needed to assert ownership of his character. What's more, Misney has broken with the industry-standard practice of turning a blind eye to creators doing sketches of their own characters for money at conventions, and singled out Freidrich for punitive, retaliatory legal claims for doing what every artist in the field does.
Finally, Misney has sought to prohibit Freidrich from publicly identifying or marketing himself as the creator of Ghost Rider, on the basis of the ancient legal principle of fuck you I said so and I can afford more lawyers than you so shut up.
As payback, not only can Friedrich no longer sell his own Ghost Rider merchandise, he can't even represent himself as its co-creator, thereby robbing him of any potential financial gain he might accrue from convention appearances and the like. (He will, however, still be able to sign officially licensed Marvel merchandise, either with ink or bitter tear stains.) In addition, Marvel is also demanding $17,000 from the unemployed, financially destitute 68-year-old, which Comic Book Resources surmises will serve as a warning to all others who currently enjoy the privilege of selling their own unlicensed merchandise, and should maybe just keep their mouths shut then.
