Overall, IPfolio is a decent way to store and keep track of legal proceedings in IP cases. Navigation is fairly intuitive, and you can mostly expect the right files to be in the right place. It is a good catch-all for correspondence and evidence and makes it easy to sort through what belongs where.
This software is full of bugs. Every other week, my team and I would have to figure out a work-around for a different software issue. We had to designate a person on our team to deal with solely IPfolio-related issues, which shouldn't be the case.
