The CR2 format is not protected by copyrights. A document about said CR2 format is covered by copyright; as can be individual CR2 files. Copyrighting a file-format is not possible per se, which is why companies such as Microsoft are "patenting" them instead (a questionable practice with questionable legal basis - but who wants to fight M$ in a court of law?) On the other hand the rigging data in said CR2 files is a tricky one. As ynsaen mentions - it is a setting specific to an application and has no realy meaning outside that context. Case law suggests that as such the extent to which copyright law applies is limited. Even in the case of it being covered, without an explicit contract, use of rigging data from the CR2 is allowed under "fair use" provisions. Case law has established that one may use portions of a copyrighted item for purposes of "compatibility" in the context of computer systems & file formats. However, this is a provision that most people are explicitly barring through the use of "restricted distribution" terms in their EULA's. So... to summarise. Without an explicit license barring said use - copyright law allows us to use the rigging data in the CR2 for the purposes of compatibility (i.e. rigging clothing for a figure). However, in practice - there is not many figures out there with licenses allowing it.
