I have actually met and had a lengthy conversation with someone who practices dressage. So any way, the Tennessee Walking Horse Breeders’ and Exhibitors’ Association has sued the National Walking Horse Association on copyright and trademark grounds. Plaintiff issues pedigree ‘registry certificates’ to horse owners. Defendant has assembled a pedigree database in part by soliciting horse owners to supply their regsitry certificates from plaintiff. Plaintiff claims copyright in its certificates. Ruling: Defedant can ask horse owners to supply the information in their plaintiff certificates but Defendants may not copy the certificates themselves, or ask for such certificates by name.
