Trademark on the Nebelung?

Wikipedia; Baker (this is the founder of the Ragdoll), in an unusual move, spurned traditional cat breeding associations. She trademarked the name "Ragdoll," set up her own registry—International Ragdoll Cat Association (IRCA)—and enforced stringent standards on anyone who wanted to breed or sell cats under that name.[2] The Ragdolls were also not allowed to be registered in other breed associations. In 1975, a group led by Denny Dayton broke rank with IRCA with the aim of gaining mainstream recognition for the Ragdoll. This group eventually developed the Ragdoll standard currently accepted by major cat registries.

In 1994, a second group decided to leave the IRCA and form their own group due to increasingly strict breeding restrictions. This group later established the Ragamuffin breed. Because Baker owned the rights to the name "Ragdoll", no offshoot groups could call their cats Ragdolls until the trademark on "Ragdoll" was not renewed in 2005.[3]
