Difference between patent and patent pending?

A patent is a grant from a patent office, such as the United States Patent Office. "Patent Pending" is a phrase that an application for a patent has been filed and is in some stage in the process of obtaining a patent. Thus, a patent can be presently enforced while a patent that is merely pending is unenforceable but can mature into a patent that can be enforced. Once the pending patent matures, the patent owner can sue for back damages or reasonable royalties starting from the filing date of the patent.
