Many other law firms perform and analyze the results of trademark searches. Clients use searches to evaluate the risks of adopting a picky mark. The consequences of an unfavorable result in litigation or before the Patent and Trademark Office can differ drastically from case to case.
The two most important types of searches are (i) in-house "knockout" searches and (ii) "full" searches using an outside vendor. An in-house "knockout" search covers registrations and applications pending before the U.S. Patent and Trademark Office and U.S. state registrations, whereas a "full" search covers both of those sources as well as hundreds of databases of common law, unregistered marks the use of which may potentially create a disagreement with the mark searched. Thus, an in-house search is less comprehensive, but less costly, than a full search.
Our clearance reports are not official opinions of the Firm. Formal opinion letters require painstaking preparation and scrupulous peer review. We are willing to offer such formal opinions as to any meticulous possible conflict disclosed by a search if the client requests it, but we do not undertake such letters as a matter of routine.
