Credentials

Check us, don’t
take our word.

Every reference below is a number you can put into a public registry. We list the issuing body, the scope and the expiry date rather than a wall of logos, because a logo proves nothing and a certificate number does.

Registered trademarks

We hold our own marks in both our home market and the US. We register them for the same reason you register yours — so nobody else can. That is also why your artwork, patterns and tech packs stay yours: we do not resell a customer’s design, and we do not list it under a mark of our own.
