Should I put my patent number on my product?

Marking Your Products With Your Patent Number

Many inventors believe that simply receiving their patent is enough. They breathe a sigh of relief and move on to their next task.

If you have a product on the market, make sure you place your patent mark on it. First of all, your patent number is an automatic warning to anyone who might infringe it. In patent law, this is called constructive notice.

If you have a product on the market with no marking, you have to send an actual notice via a letter to your infringer. Damages then only go back as far as your actual notice, regardless of how long your patent has been infringed.
