Thomas Edison did not invent the light bulb.

"It's for, like, to go back to Edison: he didn't invent the light bulb. He wasn't even close to inventing a light bulb." (said at 0:47:46)

The speaker's statement bundles two assertions: that Thomas Edison did not invent the light bulb, and that he 'wasn't even close to inventing a light bulb.' While earlier inventors (such as Humphry Davy, Warren de la Rue, and Joseph Swan) created earlier prototypes of incandescent lighting, Thomas Edison developed and patented the first commercially viable, long-lasting incandescent lamp in 1879 (using a high-resistance carbon filament in a high vacuum), along with the complete electrical power and distribution infrastructure required to operate it. Claiming that Edison 'wasn't even close to inventing a light bulb' directly contradicts the historical and patent record.

  "Specifically, this Article uses the history of patents surrounding the light bulb to examine a recently articulated theory of “patent racing” as a justification for patent protection. Thomas Edison’s experience confirms that Mark Lemley’s racing model has substantial descriptive merit." (abstract, passage verified)
