Gray later abandoned his caveat and did not contest Bell's priority. That opened the door to Bell being granted US patent 174465 for the telephone on March 7, 1876.

Invention of the integrated circuit which held the patent for Kilby's invention, started a patent war, which was settled in 1966 by the agreement on cross-licensing. There is no consensus on who invented the IC. The American press of the 1960s named four people: Kilby, Lehovec, Noyce and Hoerni; in the 1970s the list was shortened to Kilby and Noyce, and then to Kilby, who was awarded the 2000 Nobel Prize in Physics "for his part in the invention of the integrated circuit". In the 2000s, historians Leslie Berlin, Bo Lojek and Arjun Saxena reinstated the idea of multiple IC inventors and revised the contribution
