I want to know the answer to the following question:
What was the name of the company that held the patents from Edison's research?
All the background I'm provided with is that "During 1889, Thomas Edison had business interests in many electricity-related companies: Edison Lamp Company, a lamp manufacturer in East Newark, New Jersey; Edison Machine Works, a manufacturer of dynamos and large electric motors in Schenectady, New York; Bergmann & Company, a manufacturer of electric lighting fixtures, sockets, and other electric lighting devices; and Edison Electric Light Company, the patent-holding company and the financial arm backed by J.P. Morgan and the Vanderbilt family for Edison's lighting experiments.". Is that enough to answer the question?
