Use of Trademarks
Brand and product names used in this directory are trademarks of their respective companies. Rather than put a trademark symbol after every occurrence of a trademarked name, the directory uses the names in an editorial fashion only, and to the benefit of the trademark owner, with no intention of infringement of the trademark. To the extent possible, the directory distinguishes proprietary trademarks from descriptive terms by following the capitalization styles used by the trademark owner.
