I have a utility patent in China for over 2 years and I recently decided to go ahead and patent my invention in North America. Problem, because there is an existing patent in China for this invention (which is mine) and has been granted over 2 years, it is now impossible to patent it anywhere else. I just don't want to believe that I'm screwed by my own patent! How can this be, it is plain unfair. So I'm asking here if anyone knows a workaround or anything that would enable me to protect this invention.
Thanks in advance!
