Appeal No. 95-2416 Application 07/892,484 17 and 21. We reverse the rejection as to claims 20, 23 and 24. The subject matter on appeal is directed to preparations of birdseed treated with capsaicin or its derivatives or analogues in an amount sufficient to be unpalatable to animals such as rats, mice and squirrels which have capsaicin sensitive receptors. Capsaicin is an oleoresin present in capsicum (cayenne pepper, chili, pepper red) and is a known powerful irritant which causes intense pain in humans and experimental animals. In appellant’s invention, these “hot” capsaicin compounds, extracts or whole plant materials containing these compounds are coated on, impregnated in or mixed with birdseed to repel troublesome animals which recognize these compounds as “hot”. In contrast, these same “hot” compounds do not repel birds because birds do not have capsaicin sensitive receptors. Also on appeal are method claims (claims 20 and 24) for selectively repelling animals having capsaicin sensitive receptors, which claims call for the positive step of feeding the treated birdseed of the invention to birds, in an amount effective for repelling animals having the capsaicin sensitive receptors. The appealed claims stand rejected for obviousness principally in view of the disclosures of Cartwright. The review 4Page: Previous 1 2 3 4 5 6 7 8 9 10 NextLast modified: November 3, 2007
