The State of Oregon has made publicly available a list of active Oregon state trademark registrations. Unfortunately, the list doesn’t have descriptions of goods and services, a key element in any trademark rights analysis.
The processing fee for an Oregon state trademark is $50. Although an Oregon trademark doesn’t confer all the benefits of federal registration, it does have some benefits over a common-law trademark, including trademark rights extended to the entire state without having to prove the geographical reach of your trademark use and triple damages of defendant’s profits as well as attorney’s fees.
