Edison"invented" the first commercially viable lightbulb. Lightbulbs existed before "Edison's" breakthrough. They just cost an arm and a leg or burned out in minutes or hours.
A brilliant young man that worked for him pioneered a new filament for lightbulbs that were cheap and long lasting. Not necessarily the first commercially viable lightbulb filament. Some patent searching would be needed to see if the filament of the Edison bulbs used the young man's filament but he worked for Edison Inc so "Edison" patented the young man's filament. It belonged to Edison Inc.
Edison was a good promoter of himself and "his" products. Edison Inc employed many and was all about the Benjamins. Edison himself didn't invent everything he patented.

A lot like how people forget that automobiles existed long before Ford's Model T, but they were basically only toys and status symbols for the rich.
