NEW YORK & DAYTON, Ohio--(BUSINESS WIRE)--April 30, 2001

Information Holdings Inc. and Lexis-Nexis announced today that they have expanded their alliance agreement whereby LPS Group, a unit of Information Holdings, will provide Lexis-Nexis customers access to its PATEX online licensing exchange (www.patex.com).

The PATEX site provides intellectual property attorneys and their clients an online platform to showcase their available patents and technologies to prospective licensees and to look for innovative solutions and new product ideas.

The original alliance between the companies involved the license to Lexis-Nexis of intellectual property content from Information Holdings, including international patent applications and trademark registrations. The expanded alliance has enabled Lexis-Nexis to go beyond the enhancement of its intellectual property research offerings and provide its customers with an actual patent licensing site whereby patent owners and their attorneys have access to potential patent licensees in numbers previously impossible to reach through conventional means.

"The expanded alliance will advance the Lexis-Nexis goal of offering value added services to its intellectual property customers by providing not only content for research, but also the tools and services that will help intellectual property attorneys perform the tasks involved in their daily practice," stated Jeff Pfeifer, vice president of Large Law Firm Marketing for Lexis-Nexis.

The agreement establishes a co-branding, cross-linking relationship between the companies. Visitors to the PATEX Web site can learn about and link to Lexis-Nexis, and visitors to the Lexis-Nexis Patents Practice Area Page can link to the PATEX Web site to use its online licensing service. "We are pleased to form this alliance with Lexis-Nexis and look forward to helping intellectual property lawyers better serve their clients' licensing needs," commented Dooyong Lee, president of LPS Group.
