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.
There are not training offered from the patent office on getting a patent. The patent office advises you to seek guidance from a trademark/patent attorney. A good attorney is highly suggested by the patent office. As a convenience, they have a roster of local Patent Attorneys.
