I have 16 years of prior art that would fully invalidate a patent granted in 2019. The patent has two claims (effectively the same claim repeated twice). It has no preferred embodiment. I have had a working and well-publicized application since 2003. (I have a prior-art-to-claims comparison.) From the point of view of remuneration or compensation, how should I proceed?
I worked for the patent office for a little while in a TC that does some software and non transitory medium patent applications. I would take a look at the MPEP (Manual of Patent Examining Procedure) on the USPTO website if you haven't already. I doubt they would overturn a granted patent or even review it except for very peculiar circumstances.
If you are looking for compensation, a lawsuit would be your only recourse if you already have a patent on the technology to want to try and invalidate their patent. But if you don't have a patent on it why would it matter to you? The recourse for the patent office's mistakes is the court system. But lawsuits are expensive and it wouldn't affect you much unless it encroaches your own patent portfolio. If Microsoft wants to take it to court and invalidate the apple patent that is their decision.
Edit: As @George White states there is an Inter Partes review which may be what you are looking for. But again, everything costs money at the patent office and if you don't have skin in the game it may not be worth it.
