Stop ISA Trademark Violations and Misuse

ISA certifications are earned by individuals, never by a company. It requires a high level of commitment and dedication, giving ISA credential holders the opportunity to distinguish themselves from the competition. You can help ISA maintain the integrity of our ISA credential holders by reporting false advertisements and logo misuse.

What Is the Difference Between a False Advertisement and Trademark Misuse?

False advertisement is the illegal use of the ISA logos or word marks by a non-certified individual or by a company claiming to be certified. Trademark misuse is when an ISA credential holder uses the ISA logo or word mark without the required information outlined in the ISA Branding and Style Guide.

All advertisements for ISA credential holders are required to list both the individual’s name and their ISA Certification ID number. If you are unsure if an advertisement is a false advertisement or not, you can learn more by reviewing the ISA Branding and Style Guide, verifying an individual's certification status, or by submitting the advertisement to our office for review.
