Librarian for Patents and Trademarks.
Consult a patent attorney for complete patent
searching and for legal advice.
Note: A complete, comprehensive patent search is difficult if
not impossible to do using free, Internet accessible patent
databases. The databases have limitations: coverage of only recent
patents, partial text (or no text) of patents, no drawings,
incomplete information, lack of sophisticated searching
techniques, and dependence on keyword searching. A patent search
on the Internet is a preliminary search only. For serious,
comprehensive patent searching, use your local Patent and
Trademark Depository Library.
