I had made 2 inventions and has done all paper works (write ups and drawings) required to file a patent. The patent was to be filed in my boss name as first author (though hes not the inventor) and me as 2nd author. The required application forms with signatures of us were given to the patent lawyer for filing.
But after few months, I realize the patent has been filed in my boss name and my name had been omitted out. The lawyer and my boss claims, it might have happened as a mistake to omit my name and they refuse to add my inventorship claiming additional charges.
In this kind of situation what can I do? Where can I prove my inventorship?
