I like that the system allows the ability to create a patent family tree so that you can see how all the different matters are related. They also have strong reporting skills and analytics which are valuable particularly to corporate users.
I don't like the way the file wrapper/documents are laid out and I find it not user friendly for those not familiar with docketing databases. The system has plenty of bells and whistles but it is not my favorite as a law firm user. I think the way the individual pieces of a particular case file are organized to be a huge disservice to the user. Things seem to be stored all over the place, and not organized into one concise location.
It all depends on what you would like from your docketing, file management, patent portfolio system. For some clients, Anaqua is the right choice for what they desire. However, I have found that I personally prefer a different database and find it usually a better fit for both Law Firms and Corporate users.
We used the system on behalf of our client. We would docket in our own database and then docket items in the clients. It allowed us to obtain disclosure documents and inventor info without needing to bother in-house.
