For those of you who don't expand all replies, I summarize a reply above:

This is a Microsoft knock off of the Apple Magic mouse, introduced in 2009:

I'm not sure anything about it is innovative. The original mouse appeared on Apple machines long before Windows, and anyone who used a Mac Lisa or the original Mac was using the equivalent of Windows 95 in 1988. Apple licensed it GUI technology to Microsoft, leading to a dispute which was settled in favor of Microsoft. Again, it's clear who the innovators are and who the copiers are.
