Of course. Renewal applications cost money.

For utility patents there are maintenance fees at the 3.5, 7.5 and 11.5 year anniversaries. They are expensive but if the patent is still bringing in money at that time then it is worth it. If not the fees are usually not paid and the patent goes abandoned.

A patent requires maintenance fees to be paid at 3.5 years, 7.5 years, and 11.5 years. These fees are $980, $2,480, and $4,110 ($490, $1,240, $2,055 for small entities). There is also a $1,510 ($755) fee due once your patent is issued. Failure to pay any of the above fees results in an abandonment of your patent.
