We’ve started two different businesses and each time we worked with Marc Baumgartner on our trademark filings. Marc Baumgartner is professional, courteous and he knows what he’s doing. We’ve worked with many lawyers in Portland over the years on our businesses and we found Marc to be the most vested in our success. He’s also trying to save us money at every turn. He keeps his promises and he’s successfully obtained several US trademarks for our business. Highly recommend if you need trademark or patent legal work.
