Can you explain what those were? Most people think he "invented" the light bulb, that's what is taught in school, but he just perfected it. But he did end up patenting the "Edison base" for the light bulb, so none of the others that thought of other ways of making them couldn't use his screw in base.He did invent one or two things
To me the story of Edison is like the story of the founding fathers of the USA, written by people that want them to look like they were out to help us all. But newer research into things in the National Archives and letters written between them and others from the time period, things that were overlooked for a long time, is painting a different picture of things. Will it get changed in history books in the schools? Probably not, but at least the truth is finally getting out.
