1093 US patents were granted to Thomas Edison in his lifetime, as well as several hundred patents in the UK, France, and Germany.

Many of them, such as the "light bulb" were ruled invalid in a federal court, due to Edison's having stolen and copied materials from others and claimed it as his own.

Second alteration. Using the term of "stolen" regarding patent disputes maybe not that accurate.
