Caseflex - Next Generation Legal Research. Caseflex is a new Internet based service that allows Federal practitioners to track the docket of any District Court case, find any District Court case, receive email alerts for any docket being tracked, download filings, and more. Sign up for the demo and you will receive $50 in credits for searches, downloads, and so forth. The front end is an easy to use access point for PACER and the information it contains. The $149 per user monthly charge is a no brainer for lawyers with a heavy Federal practice. Legal research online gets better everyday.
