Thats like saying I helped pay for your hamburger at Wendy's you bought today, because i bought a hamburger last week.
It would be criminal to resell research someone else payed for. its a product someone bought and paid for.
If someone orders the same thing they start from scratch just like a hamburger.
If they already researched it once of course its easier, but still different. Just like making your 17th hamburger. After 1000 it becomes harder again.
