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

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

Yeah it is surprising. Shimano have been slow to catch up with trends over the years but thats maybe starting to change now, grx etc
Will be interesting what the next gen DA group will look like. It seems most likely it will be a wire going to a battery, but even that is still too much faff compared to etap for me.
I've read some online rumours that a new 12 speed DA group could be arriving this spring but I'm sceptical. If a 12 speed DA group was ready for release in spring then there would have been the inevitable spy shots of it appearing on pro bikes for the past few months. I haven't seen any at all yet, the supposed spy shots of Remco Evenepoels bike was very obviously 11 speed DA.
Recently seen articles showing shimano patents for groups using piezoelectricity, but cant imagine thats coming to market any time soon.
