In a manufacturer's action for defamation, trade libel, false advertising, and unfair business practices, arising after defendant-attorney published a newspaper ad stating that users of certain brand name galvanized screws under specified circumstances "may" have legal rights to compensation or other relief, grant of a motion to strike the complaint is affirmed where: 1) the suit was a strategic lawsuit against public participation (SLAPP) which is subject to summary disposition under the anti-SLAPP law; 2) the suit was not exempt from that law as a statement "about" the attorney's services, or one made in the course of delivering those services; and 3) the manufacturer did not establish the requisite likelihood of prevailing on the merits to avoid a dismissal of its action.
