Applicant Haden sought a registration on the Supplemental
Register for the mark shown below, for "Medical and health
care services, namely, medical treatment of allergies, asthma,
immune disorders, and shortness of breath." The Board agreed
with Examining Attorney Andrew Rhim that the term ALLERGY
CARE is generic for the recited services, but it concluded
that the mark is registrable on the Supplemental Register with a
disclaimer of ALLERGY CARE.
In re James Haden, M.D., P.A., Serial No. 87169404
(December 4, 2019) [precedential] (Opinion by Judge Thomas
Shaw).

Because Applicant Haden sought registration on the Supplemental
Register, he conceded that the proposed mark, as a whole, is
"at best merely descriptive" of his services. Quaker
State Oil Refining Corp. v. Quaker Oil Corp., 453 F.2d 1296,
172 USPQ 361, 363 (CCPA 1972) The question was whether it is
generic.
