After months of dishing out Y2K advice to clients, D.C.’s top law firms are reviewing their own millennial checklists, anxious to enter the New Year with all their briefs intact.

Patton Boggs, for example, plans to shut its computer systems down on Dec. 30 and bring them back up Jan. 2 to give the firm’s technical staff plenty of time to identify and fix any problems. Arnold & Porter has instructed all its lawyers to copy important documents onto diskettes, particularly if they are working on deals that are not completed by Dec. 31. And patent firm Sughrue, Mion, Zinn, Macpeak & Seas has already simulated the 2000 date change on its computer system.
