Assuming you have your patent issued AND you make and/use the patented product AND that product infringes another patent, the following is my suggestion.
Suppose your patent claims product comprising A, B and C. And another's patent ("superior patent" hereinafter) claims only A and B.
Then, if you produce or sell product having A, B and C, you are infringing superior patent, because your product have A and B. It does not matter your product also has C.
If such being the case, the patent holder of superior patent CANNOT produce or sell product having A, B and C.
So, safest way to avoid infringement suit from superior patent holder is to stop producing and selling product having A and B.
Next option is to propose the holder of superior patent for cross-licensing each other's patent, which avails you to use the superior patent and avails title holder of superior patent to use YOUR patent.
You must not withdraw your patent. By doing so, you will lose the second option.
