A couple articles (both via beSpacific) on the move to e-filing of documents by the U.S. government. The first article deals with e-filing of documents within in the judicial system. No specifics, but does track progression of these initiatives from its current nascent state (merely scanning paper documents by the courts), to the full realization of document submittal in XML.

I tried to play around with several of the courts they mention, but they all required an official login.

The second link has to do with the e-filing at the U.S. Patent and Trademark Office. They've begun filing electronic versions of documents on June 30 using a system they call Image File Wrapper (IFW), which seems to boil down to merely scanning existing applications. The eventual goal is to create an "end-to-end" patent application process by October, 2004. The initial iniative will require 100 terabytes of data storage.
