I have found instances where a logos are restricted. Here is such an instance.
Business and Member Cards – ASHRAE Rule of the Board 1.201.025.1
This policy applies to all Member and ASHRAE professional certified individuals business cards. It does not apply to business cards prepared at Society headquarters for use by the Executive Committee and staff.
A. The name “ASHRAE” and the ASHRAE logo are trademarks of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers, Inc.*
Use of the ASHRAE name and/or logo shall not imply or be used to imply in any way, ASHRAE’s
endorsement of the member’s company, products or other commercial interests.
B. These trademarks may not be used except as
- For an ASHRAE Member Card – a business card outlining only ASHRAE member affiliation, service and contact information provided
a. The member whose name appears on the card must be a member in good
standing of the Society.
b. The ASHRAE logo and tagline may be used as long as it follows the ASHRAE Logo Guide
c. No company or organization logo, other than the ASHRAE logo, may appear.
Nothing about competing logos on website, social media and any and all marketing and advertising materials.
So in my view the policy is still to restrictive.
