Myself and a co-worker developed the methodology for performing a process (software development), and we even helped author the claims for the provisional patent application, yet we have been left off the patent as inventors. What kind of recourse do we have on this type of situation? I mainly just want my name listed as an inventor on this patent. Thanks!
