Patent searching is complex and time consuming. Plan on spending a few hours learning the search process and additional hours searching and evaluating results.
You will need to document your search. Keep careful records of which patent databases you search, what keywords and classification numbers you search in the databases, document numbers of the patent and application documents that you retrieve and examine, and the date and time of your search.
Keyword searching alone is never enough. A comprehensive patent search requires that you search by classification and sub-classification numbers.
