First please note that I am not a lawyer. I don't think we can answer your question with certainty, but I will point out a few things to consider. First, while your patent provides protection for your technology, it doesn't guarantee freedom to operate. As an example lets say the patent for pneumatic tires were still in force. Someone could invent and patent the radial tire as an improvement, but would still need a license to the original pneumatic tire patent since a radial tire would infringe the original patent. Also, your product might implement other patented technologies such as wifi chips that require licensing. Thus, having a lawyer perform a freedom to operate analysis is a good idea.
In general, patents are used to keep someone else from manufacturing or selling the patented technology and don't incur any government paperwork (that I know of) for sale of products. However, depending on the type of product and the locale of sale, there can be government regulation. An obvious example are medical devices which may need to be approved by government entities before being marketed.
The bottom line is that you really can't rely on internet sites like this for legal advice on your specific situation. Competent legal advice is a necessary requirement for running a business these days and I would recommend you consult with an attorney.
