I have collaborated with Richard Gold, who came to make a presentation here, I believe. We work a great deal on patent pooling for various diseases, among other things. It is one of the nice ways to encourage researchers to collaborate and to make interesting discoveries.
We have to understand that the current model granting intellectual property rights for ongoing research is becoming more and more of an obstacle. So, based on the current model, extending those rights is a roadblock to discovery rather than an incentive.
