The ‘patent’ from Autel is more like ‘we made a white circle painting on the CCW clip props and left it black on the CW clip props’, so if the Anafi 2 has another way to avoid mismatches and to install the props (with screws for example), they won’t infringe any patent.
The Autel patents will be struck off I would think - they patented a locking mechanism that has been used on toys (e.g. corded spinners toys) to medicine bottle caps to power tool blade locks over last 50 years.
The patent also included 'the unique' feature that the lock has 2 version one clockwise and one anticlockwise so that you cannot put the wrong props on the wrong arm!!
Proper failing by the patent office in issuing them and I would expect DJI will have them struck off the register.
