Legal Question in Technology Law in Illinois

You are correct that raw data is not copyrightable material. It is the arrangement of the facts (the way they are expressed, compiled, presented) which is the copyrightable element. Be sure not to copy the way the facts are presented, and you should be okay from a copyright law perspective. However, if the company is claiming proprietary rights to the facts themselves (it is data that they obtained through research and analysis), and prohibits commercial use of their facts, you still have a problem. One would need to look at your exact situation to give you a proper evaluation of how to proceed.
