Who invented the laser mouse?

The invention of the laser mouse is credited to Robert S. Sutor, while working at Microsoft. He filed a patent for it in 1999 and the technology was first commercially used in the Microsoft IntelliMouse Explorer released in 2004.

However, it's important to note that while Sutor is credited with the invention, the technology builds upon previous work in laser imaging and optical tracking, which were already in use in other fields.
