They scuffed with Autel and initially lost (but then had that patent invalidated), and their currently brewing fight is with Bell Textron for camera control.
(This is just a quick googling. I have no skin in this game either way, but I believe that the assertion that Chinese companies always steal is a bigoted position to take. Perhaps a more accurate description would be that IP is most commonly held by incumbent businesses, and businesses in China in new segments are, necessarily, new to market.)
I think the last point you make is a big one, and partially used to justify the Chinese industry behavior. Basically China is late to the game and if they follow Western rules they will be perpetually behind, partially because such rules are obviously designed to preserve wealth.
That being said, there is still plenty of legit innovation coming from China and Chinese founders/contributors: ant framework for react, vue, tiktok.
I don’t think it’s a coincidence a lot of the innovation is in the software sector, especially ML, which has less incumbent IP protections.
