In the patent dispute over celluloid film, which side did the courts rule in favor of?

• A. Goodwin
• B. Eastman
• C. Edison
• D. Lumiere Brothers

Answer: (A)

Patent disputes center on who owns a valid, enforceable claim to a specific invention and the rights to use it. In the celluloid film case, Hannibal Goodwin held the patent on the basic method of making flexible film from nitrocellulose (celluloid). The courts upheld his patent, recognizing that his invention was legally protectable and enforceable against challengers, so the decision went in Goodwin’s favor. This outcome meant that Goodwin’s claim to the celluloid film technology stood, at least against those opposing it, while challengers like Eastman faced the consequence of that ruling. The other parties listed were major figures in the industry, but this particular ruling favored Goodwin.
