As an LLC, how can I handle being sued for patent infringement if I don't want to go to court?

I started a LLC company in the area of face image analysis. We have three patents approved, but there are quite a few patents out there in the topic. If a company sues us, even if I know it is not a valid patent and I can win the case, I definitely do not want to put the resources (time and money) to go to court. Can I do the following: 1) Keep the products that are liable in the LLC company and close the company, that way I do not have to go to court. In this case, if I already spend the money I got from the sale of the product with infringement, then I do not have to pay anything right? 2) Start a new company with other products that are not liable…
