Is there any way of searching the USPTO Trademark Database for images, in addition to words and phrases?
Yes, you can search the U.S. trademark database for specific types of images. Each type of image has its own design code. For example, the design code for an igloo is 07.01.09. Any trademark depicting an igloo can be found by searching the database for that design code. To view a list of design codes, see the U.S. Patent and Trademark Office’s “Trademark Design Code Manual”. Once you know the design code you want to search for, search the USPTO Trademark Database using the “Structured Search” option. In one of the search boxes, enter the 6-digit design code, WITHOUT the periods.Select “Design Code” from the pull-down menu next to the search box. Then click on the “Submit Query” button.For example, a search of design code 070109 will find all registered (and “dead”) logos containing the image of an igloo.
