I agree with dipanpatel regarding the ownership of IP. I also believe in having a good lawyer to have a look at the agreement before they go onboard the with the study. Some firms have a strict policy of IP ownership and some are flexible with IP claims. Also, if the lab is not investing but assisting with the study, more or less, the innovation which comes out of the study or test is claimed by sponsored. When the study is jointly conducted, there is room for negotiation with the split.
