BlackBerry Expands Leadership in the Legal Sector with Integrated Email, Phone and Data Applications

Popularity Continues to Grow with Both Large and Small Law Firms

New York - Legal Tech Conference - The BlackBerry® wireless platform, developed by Research In Motion (RIM) (Nasdaq: RIMM; TSX: RIM), remains extremely popular in the legal sector as RIM and its channel partners continue to expand the value of BlackBerry with integrated email, phone and data applications. Over 85% of AmLaw 100* and 70% of AmLaw 200* law firms have already selected BlackBerry; and small and medium-sized law firms are also broadly deploying BlackBerry following the introduction of services for smaller companies by RIM and its carrier partners. Both users and IT departments inside law firms are applauding the impact of BlackBerry on productivity and client service.

"There's absolutely no doubt about the effectiveness of BlackBerry during crunch time. The ability to do things wirelessly is incredible and BlackBerry has greatly increased my productivity level and ability to satisfy clients," said Jerry Markowitz, Managing Partner at Markowitz, Davis, Ringel & Trusty, P.A. "I frankly don't know why anyone would have any other product; BlackBerry is clearly the best on the market."

"Our firm initially deployed BlackBerry as a technical support tool, and once our attorneys saw how BlackBerry transformed the way we manage email and business communication, we knew a broader implementation was next," said Peter Conn, CIO, Cole, Raywind and Braverman. "It's my job to ensure that our attorneys and support staff are utilizing the best technologies to service our clients and maintain the highest levels of productivity. I've examined other technologies but I have found no better solution than BlackBerry for secure, integrated, wireless access to our email and information."

BlackBerry is an award-winning solution that supports wireless access to a wide range of information and communications through email, phone, corporate data, SMS, organizer and Internet applications. For smaller firms, BlackBerry Web Client™ allows users to access multiple existing corporate and/or personal email accounts from a single BlackBerry handheld. For larger law firms with an IT department, BlackBerry Enterprise Server™ software tightly integrates with Microsoft® Exchange or IBM Lotus® Domino™ and works with existing enterprise systems to enable push-based, secure, wireless access to email and other corporate data.

Through the Mobile Data Service feature of BlackBerry Enterprise Server, many firms have also extended their corporate applications to BlackBerry or enabled additional applications such as time and billing management, CRM (Customer Relationship Management), case management, document management and research tools.

"Attorneys using BlackBerry handhelds to wirelessly track their billable hours anywhere; whether away from the office, in a meeting, at a client site, or at home will record their time more accurately," said Jim Tharpe, President, at Advanced Productivity Software, Inc., developer of DTE (Distributed Time Entry). "Integrating DTE with BlackBerry greatly enhances attorneys efficiency by ensuring that billable time is more accurately captured and not a minute of billable time is lost."

"Westlaw is a powerful research service that provides access to a vast library of legal and business information," said Terry Dick, Director of Technology Marketing, Thomson West, developer of Westlaw. "Attorneys can use their BlackBerry handhelds to wirelessly retrieve cases, statutes, regulations, news, public records, topical materials and more. Wireless access to this information through BlackBerry provides attorneys with increased productivity regardless of their location."
