We have a team in fact that evaluate the FDA requirement and looking at what would be the best way to do it.
Also, Open IP means for us that we will share the modified strains which are optimized for the expression of the insulin, and ideally, we will be able to provide scientific knowledge and resources to help the creation of local manufacturing plant.
If they cribbing off a "process patent" then it's not reverse engineering, though, IIRC, for most drugs companies don't bother getting a process patent because they are very difficult to enforce (to enforce such a patent, you need a warrant to go onto a competitor's premises and inspect their process, and judges are very very unlikely to issue such a warrant because if they set a low bar precedent for such actions, then basically everyone is going to start issuing spurious claims), so everyone would rather just build their moat with trade secrets than process patents. Also, I believe if you crib off of a process patent to do a one-off run or research project it is not illegal, only commercializing it is. One (ostensible) point of patents is to encourage sharing and desiloing knowledge and keep things out of the dark so that we can learn from each other.
Where are you getting this from? This goal of this isn't to have every diabetic brewing insulin in their garage so they evade the IP police in a distrubuted fasion. The goal is to create open IP needed for creation, purification and quality control that will allow labs around the world to create insulin in keeping with local regulations.
