Jennifer M. Lantz has more than 20 years of experience helping clients at all stages protect their brands and other intellectual property. Ms. Lantz focuses on helping companies develop brands through enforcement policies, clearing marks for use, registering marks in the United States and abroad, commercializing marks through licenses and merchandising agreements, assessing infringement risks, enforcing trademark rights and defending against allegations of infringement.
