I know, right?!
I don't have any knowledge of how patents work really, but wonder if it's a time limited thing and will eventually expire?
Or Shimano will somehow get around it with some clever key difference? Or just ignore it and go with removable batteries on the mech?
I find it hard to believe such a thing can be patented.I cant find any solid info on it all online, googling leads me to folk arguing about it here on weight weenies https://weightweenies.starbike.com/forum/viewtopic.php?f=3&t=156208&start=825

You can patent software concepts, so patenting a physical concept like a removable battery for a mech is perfectly reasonable. Shimano themselves have multiple patents granted so they play the game themselves. They can’t copy what SRAM did unless they agree a license with them, but I’m sure there are Shimano patents that SRAM would like access too, so a cross licensing patent agreement should be possible. That’s how it works in other industries.

Really such a thing as wireless derailleur with removable battery should not be patentable worldwide. Stiffles competition.
