A patent can usually be issued on one or both of two grounds: it is either an original process/machine, or it is an original alteration or improvement to an existing one. If you were to do so the new product must be clearly original and different, instead of relying on the first patent.
You have to file a Utility patent application form with The United States Patent and Trademark Office. A utility patent applies to any invention or new useful improvement thereof.
Most patents issued today are for improvements on existing products; all you need to do is indicate the patent numbers and titles in the first sentence of the specification in your application.
