The Trademark Trial and Appeal Board (“TTAB”) found confusion was likely when the identical GUIDEON mark was used to identify both the petitioner’s downloadable software app providing a services directory and navigation for military personnel and the respondent’s online employment information services for veterans. But the TTAB also held that the respondent’s educational services were sufficiently different from the petitioner’s software app, and outside its natural zone of expansion, such that confusion was unlikely with regard to those services. Consequently, the respondent’s challenged trademark registration was only cancelled in part.
