The computer mouse In 1967, Engelbart applied for, and in 1970 he received a patent for the wooden shell with two metal wheels, describing it in the patent application as an “X-Y position indicator for a display system”. Engelbart later revealed that it was nicknamed the “mouse” because the tail came out the end. His group also called the on-screen cursor a “bug,” but this term was not widely adopted. He never received any royalties for his mouse invention, partly because his patent expired in 1987, before the personal computer revolution made the mouse an indispensable input device, and also because subsequent mice used different mechanisms that did not infringe upon the original patent. During an interview, he says “SRI patented the mouse, but they really had no idea of its value. Some years later I learned that they had licensed it to Apple for something like $40,000.”
