when going for a patent, companies will claim as much as possible. They basically try to cover and get away with as much as possible. Then they narrow it and resubmit, sometimes multiple times until they find the sweet spot at the right time. This is not a unique strategy and one that their patent attorney would have recommended.

You're ok at Googling but need to take it a step further to interpret. Get it interpreted from those with experience. I have done this with a medical researcher with experience in exactly this. I have also consulted two brokers and a biotech analyst at a mid sized broker with no conflict.
