First, let's see whose patent application date is earlier than yours and the other's.
If your application date is before, your product is the same as your patent, and there is basically no problem.
If the other party's patent application date is before, and your patent and/or your product are similar to it, and ordinary consumers can't distinguish it, then the possibility of your patent being invalid and the possibility of your product being judged to be infringing is greater.
In the latter case, you can also ask the other party to issue a patent evaluation report, which is equivalent to a substantive examination of his patent. If the other party's patent is unstable (there are problems such as novelty in the report results), your problem is not big.
If the patent evaluation report issued by the other party has a good result and the patent right is stable. You may need to be prepared to coordinate and stop the infringement at any time, or ask a professional organization to declare the other party's patent invalid.
