It’s great to have customer logos in your new brochure or to have their logos sprinkled throughout your website. But don’t do it without permission!! Logos are typically protected by copyright and trademark law, let alone by what are often very complex rules of use. Bottom line – it’s actually illegal to use another company’s logo without their consent. Even if you’re selling or promoting their products you need consent. If you’re implying they are a happy customer of yours then you really need consent!
Development of a brand can cost a great deal of time and money. Companies want to protect that investment. The little extra work of asking permission and using their company name and logo according to their guidelines can go a long way both professionally and legally.
