I am current graduate (international) student in a chemistry lab in USA which filed a provisional patent. I just discovered a few days ago that I am not the inventor on the patent although I solely made the product (compound) that we filed patent for. I am the first author on the publication and everyone acknowledges that I did that work. When I asked my professor about it he said we filed that patent long long ago and had no satisfactory answer that why I am not on the inventor list. How could he file a patent without making the product that he is claiming in the patent. I have all the data and experiment properly written in my log book. He included the names of two other students which have minor contribution on that work. I am finishing up my 3rd year but I have 2 more years to work with him. What options I have to get the corrections on the inventors names? Thanks!
