I'm surprised Apple didn't co-opt charging mousepad tech, like what Logitech uses:
The product is already several years old after all (release date 2017)
Or bypass the idea of the patent altogether by making their mouse charge wirelessly and then releasing a giant wireless charger that happens to work pretty well as a mouse pad later.
Option 2 is a great way to land in court. It's one thing to steal IP from a tiny company or individual but Logitech can afford lawyers.
