(a) Except as provided by Subsection (b), it is an unfair method of competition or an unfair or deceptive act or practice in the business of insurance to use, display, publish, circulate, distribute, or cause to be used, displayed, published, circulated, or distributed in a letter, pamphlet, circular, contract, policy, evidence of coverage, article, poster, or other document, literature, or public media:

(1) a name as the corporate or business name of a person or entity engaged in the business of insurance or in an insurance-related business in this state that is the same as or deceptively similar to the name adopted and used by an insurance entity, health maintenance organization, third-party administrator, or group hospital service corporation authorized to engage in business under the laws of this state; or

(2) a word, symbol, device, or slogan, either alone or in combination and regardless of whether registered, and including the titles, designations, character names, and distinctive features of broadcast or other advertising, that is the same as or deceptively similar to a word, symbol, device, or slogan adopted and used by an insurance entity, health maintenance organization, third-party administrator, or group hospital service corporation to distinguish the entity or the entity's products or services from another entity.

(b) If more than one person or entity uses names, words, symbols, devices, or slogans, either alone or in combination, that are the same or deceptively similar and are likely to cause confusion or mistake, the person or entity that demonstrates the first continuous actual use of the name, word, symbol, device, slogan, or combination has not engaged in an unfair method of competition or deceptive act or practice under this section.
