It seems I need a license to shoot MPEG-4 videos? (Canon EOS R; AT&T patent)

The Canon EOS R Advanced User Guide states on page 629 thatThis product is licensed under AT&T patents for the MPEG-4 standard and may be used for encoding MPEG-4 compliant video and/or decoding MPEG-4 compliant video that was enconded only (1) for a personal and non-commercial purpose or (2) by a video provider licensed under the AT&T patents to provide MPEG-4 compliant video. No lincense is granted or implied for any other use for MPEG-4 standard.Does this mean anyone who takes videos and uses them for commercial purposes is in breach of license? I'm in particular thinking of youtube uploaders with a view to profits, or wedding videos, and even including people and companies that do camera reviews, for example, DPReview, etc.​I'd be grateful for some insight and how this is meant to work in the real world and maybe in different countries.​edit: expanded to quote full license text. via /r/photography http://bit.ly/2Tt0GhT
