Laser Energetics Inc. of Mercerville, N.J., has announced that the trademark application for its Dazer Laser handheld, nonlethal light-fighting technologies has withstood a challenge from Taser International Inc. of Scottsdale, Ariz. The latter had contended that the trademark was too similar to its own Taser trademark and should be rejected by the US Patent and Trademark Office. Taser International, a provider of electronic control devices, terminated its opposition with prejudice. Dazer Laser is a developer of products for applications in industry, science, medicine, homeland security and the military.
