Refusal of E-Prefix Registrations Continue to be Affirmed by TTAB

Applications for "E-prefix" marks are regularly rejected by the U.S. Patent and Trademark office as being merely descriptive. It happened again to the applicants in three recent cases discussed by John Welch in The TTAB Blog:

• E-MANUFACTURING for rapid prototyping equipment and related training and educational services by EOS GmbH Electro Optical Systems
• ECOC for software which supports the manual entry of data into a designated form which can be transmitted and/or stored on computer based media by Envirosolve Corp.
• E-LAMP for metal halide lamps and lighting systems by Advanced Lighting Technologies, Inc.
