    Foreign patent prosecution services are the key business of HAIHAN-IP. Most of our patent attorneys have gained experience by dealing with a number of patents in varied technical fields. When doing our patent work, we put our selves in applicants’ position to know what we should do to obtain granted patents in the most effective way.
