ISO's brand and reputation: Quality, confidence, and trust
For standards users, customers and consumers, ISO means quality, confidence, trust, safety and many other positive values. That is why we and our members care about how ISO's trademarks are used and whether unauthorized use of the ISO trademarks could mislead, create false impressions, or cause confusion.
We and our members (located in many countries worldwide) will take appropriate action if we consider the misuse of ISO's trademarks puts our reputation at risk.
We have successfully initiated many legal actions including national trademark actions, notice and takedown claims (including under the Digital Millennium Copyright Act (DMCA)), and domain name abuse claims under the Uniform Domain Name Dispute Resolution Policy with the WIPO Arbitration and Mediation Center.
