This is getting off the topic of phonographs, but there actually were quite
a few light bulb inventors before Edison that put filaments into evacuated
glass bulbs and patented their ideas. Edison's bulb was considered practical
when he came up with a filament that was bright enough, would last long
enough, and could be produced at a cost reasonable enough to be commercially
successful.

This is my pet peeve! Edison DID invent the light bulb. To say he only
perfected it is ridiculous. By definition, a light bulb consists of a
glass bulb with a filament inside. Only Edison had that. This would be
like saying that whoever invented "stairs" also invented the escalator,
because the fact that the "moving" part is not significant to the
definition of "escalator".
I think it is most telling that no one was selling light bulbs before
Edison, and that Swan had actually stopped working on the light bulb
before he saw what Edison did. Then he suddenly started crying that Edison
stole his idea. Heck, for all the success that Swan had, he might as well
have put a candle in a glass globe.
