3Com and Inventor Dr. Brent Townshend Announce First Patent Issued for 56K Modem Technology

Business Wire, Sept 2, 1998

SANTA CLARA, Calif.--(BUSINESS WIRE)--Sept. 2, 1998--Global networking leader 3Com Corporation (NASDAQ:COMS) and independent inventor Dr. Brent Townshend today announced the issuance to Townshend of U.S. Patent Number 5,801,695.

This is the first of several anticipated patents covering Townshend's inventions embodying the pulse code modulation technology basic to making a V.90 or any other 56K(a) analog modem.

3Com, formerly U.S. Robotics(R), was the first to introduce and market a 56K(a) desktop modem, PC card and server with this technology and has been the leader in the 56K market ever since.

Townshend's Innovations Create New Era of Communications

Townshend's inventions are believed to be fundamental to the technology breakthrough that led to the development of 56K analog modems. This began with 3Com's U.S. Robotics brand x2(tm) technology implementation, and culminated, earlier this year, in the determination of the final ITU (International Telecommunications Union) V.90 standard.

3Com engineers also contributed numerous inventions relating to the successful implementation of 56K technology in the company's market-leading x2 and V.90 modem products.

"Townshend's groundbreaking work allowed us to create a new product that drastically improved analog modem connection speeds. His invention revolutionized the way people all over the world experience the Web," said Dale Walsh, vice president of Advanced Development at 3Com.

3Com Continuing to Lead the Market

Townshend initially approached 3Com in 1995 with his idea for the next generation of modem communications, and the company has been developing implementations of 56K modem technology since 1996. 3Com submitted the first 56K proposal to the ITU in September 1996 and has continued to lead the push toward standard-based 56K technology.

Using its proprietary x2 technology, in February 1997, 3Com became the first vendor to ship 56K modems. A year later, shortly after the V.90 standard was determined by the ITU, 3Com was first to market with modems that were compliant with the new 56K standard.

3Com holds an exclusive license to Townshend's technology, including his patents. Further, 3Com and Townshend have both indicated their intentions to offer licenses under their respective patents covering V.90 standard modems to all manufacturers on reasonable terms. Specific license terms are available to interested parties upon request.
