What was the specific patent number granted to Alexander Graham Bell in March 1876?
Answer
Patent No. 174,465
The formal protection for Alexander Graham Bell's telephone concept was secured very quickly following the initial patent application filed on February 14, 1876. Bell was officially granted Patent No. 174,465 just a few weeks later, specifically on March 7, 1876. This patent number is the key legal instrument that secured his position as the patent holder for the invention of the telephone, even as other inventors like Elisha Gray were filing related documentation on the very same day the application was submitted.
