Open source licenses traditionally have give permission for people to do what would otherwise be prohibited by copyright law; i.e. copying, modifying and redistributing the software. But if you have a patent, people are still forbidden from doing that, by patent law.

The way out for you would be to use one of the license texts which include a patent grant in addition to copyright license; e.g. either the GPLv3 or Apache 2 licenses.

Of course, if you do that, one could well ask what you wanted the patent for in the first place.
