Intellectual property doesn’t just sound cool. It is cool! Over at The American Prospect they’re pulling apart the IP issues surrounding Tony Stark’s Iron Man suit. Government takings abound!
While trying to fend off Vanko, Stark is pressured by the U.S. government to give up the secrets of the Iron Man suit. After Stark refuses a senator’s demand that he relinquish his body-armor technology, the government forcibly takes it from him, only to turn it over to a competitor that then uses the technology to fulfill its own defense contract. Consciously or no, this echoes the real world; the United States government can take such actions with almost total legal impunity.
Tony Stark gets to choose: disclose the details of the invention in a patent and correspondingly get superior civil (i.e. monetary) relief if someone copies it, or try to keep the invention secret himself and hope that criminal law dissuades people from stealing it.
