I trust the AOM will handle this the moment Sisvel actually attempts to file suit. If their patents are as solid as they're claiming, they probably would have sued someone like Netflix for using AV1 already. IIRC, Sisvel did this for both VP8 and VP9 and it didn't end up going anywhere.
There's going to be a lag time before enough HW is being used that fully supports it but it'll happen eventually.
