Notes: With the above you get what you pay for. All of the search engines work differently. This requires hours of reading each help file to ensure accurate results if searching more than one authority.

When conducting a trademark search, it is important to search each state database for conflicting trademarks.. The individual state databases will be listed in the future. All fee based systems have all 50 states available for searching. Only three have proprietary state databases. They are Thomson, CCH/Corsearch and www.Trademark.com.
