You have two issues, first is legal, second is IP. Legally, most companies make you sign a contract stating that you will not distribute or sell their data and that it is required to stay on one machine. Other companies like Activ or Bloomberg B-Pipe allow you to distribute the data but charge you $15k+ per month.
Short answer is chances are, no, you can not distribute or sell it.
Second issue is that you have now massed up a database that could be worth as much as $100k. I value my 3-years of Russell 3000 tick data around $100k for insurance purposes. #1 its logisticlly hard to sell because of the sheer size (I'm at 20TB and not completed the full 3 years yet) and #2, you will be giving up your edge as well as whats to stop someone from just copying your data and reselling it?
I have been working on an application that will allow users to (eventually) license use of my tick data without actually seeing it. Its essentially a backtest engine that can be accessed over the web. This is a long time out & not a sales pitch because it is no where near ready.
Also, most of the "tick data" you can buy out there is junk. It's usually bars, limited securities, etc.
