18.6Royalty-free Codecs
In order to help with the discussion on royalty-free codecs, several National Bodies provided input as requested in N11066 Call for Comments on Possible Future activities on “Royalty-free” Standardization by MPEG. MPEG thanks with N11222 Responses to NB position statements on N1066. No clear conclusions could be drawn from the diverse responses. Furthermore, neither MPEG nor ISO can guarantee that a standard developed with the goal of being RAND or royalty-free will actually be RAND or royalty-free since the analysis of patents is outside of the scope and competence of ISO and MPEG.
MPEG issued document N11221 Possible future actions on standardization with Type 1 licensing where the legal issues are summarized and discussed. Type 1 licensing refers to option 1 of the joint patent declaration form, where an intellectual property holder can indicate that he will not charge for his IP. Laymen refer to this type of licensing as royalty-free.

However, MPEG believes that 20 years after its publication some technology will become royalty-free. Since parts of MPEG-1 and MPEG-2 were published in 2013 and 2014, candidates are a MPEG-2 Part 2 baseline profile carved out of MPEG-2 Part 2, MPEG-1 Part 3 Layer 2 baseline profile carved out of the MPEG-1 part 3 Layer 2, a MPEG-1 Part 3 Layer 3 baseline profile carved out of the MPEG-1 part 3 Layer 3, and a MPEG-2 Part 1 baseline profile carved out of the MPEG-2 part 1. These candidates would be compatible with existing equipment. Alternatively, MPEG may define a new set of standards which are believed to be RF provided such standards provide sufficient differentiation to be successful in the market place.
