World Trademark Review named COJK and trademark attorneys Everett Fruehling, Jerry Nagae, and Melissa Nowak to the 2018 edition of WTR 1000 – The World’s Leading Trademark Professionals. The guide ranks COJK amongst the top ten firms for trademark law in Washington state, noting the "esteemed Seattle boutique puts over a century of combined experience at the disposal of its clients, meaning no trademark conundrum goes unsolved."  The team is also recognized for its "international percipience," and "deft touch when it comes to new branding initiatives and global portfolio management."

The WTR 1000 guide identifies leading practitioners and law firms exclusively in the trademark field in 70 key jurisdictions globally. In compiling the rankings, researchers consider information provided from law firms on their work over the past year, insight from other legal professionals, and the perspective of the clients benefiting from their work. Individuals and firms qualify for a listing on the basis of their depth of expertise, market presence, and the level of work on which they are typically instructed.
