STAMPS.COM ACQUIRES E-STAMP’S NAME, PATENTS

Stamps.com acquires Internet-based postage assets and intellectual property of former competitor.

Santa Monica, Calif. — Stamps.com, the leading provider of Internet-based postage and shipping services, announced today that it has acquired a broad set of 31 patents and other intellectual property rights from E-Stamp Corporation, including the E-Stamp name and E-Stamp.com Internet domain.

The portfolio of patents and trademarks mostly relate to Internet-based postage printing and management, and are part of a broader strategy by Stamps.com to solidify its leadership in mailing and shipping services within the small business and home office markets.

“These acquisitions significantly enhance our position in the rapidly growing Internet postage and shipping areas,” said Stamps.com chief executive officer Bruce Coleman. “Combined with our existing intellectual property assets, the E-Stamp patents and trademarks provide us with a technology portfolio and brand recognition that places the company solidly at the forefront of Internet postage providers.”

Once a Stamps.com competitor, E-Stamp Corporation announced in November, 2000 that it would exit the Internet-based postage industry to focus on shipping and logistics.

Stamps.com plans to use the E-Stamp assets to expand the services available to its customer base and target market of 10 million small business and home offices in the United States.
