AppColl.com is cloud-based, very reasonably priced, and great on pure docketing and tracking. But my take is it's more directed to practicing patent attorneys (whether law firm or in house). It has a very "database" feel. I'm not sure it's going to be very satisfying for your business-oriented reporting requirements.
You might also want to look at Anaqua. It is literally an order of magnitude+ more costly than AppColl, but I have been hearing about it a lot lately from the business-side and it may offer more if the pricing is in range.
I just started work developing a new law firm-independent SAAS offering that is similar to what you're looking for, although we're very early stages and initially focusing our MVP on a subset of that functionality important to early-stage startups. I would be happy to chat offline re: whether it may be helpful to you.
