The reflecting telescope was invented by Sir Isaac Newton in the early 1600s. This was before there was a patent office, and no patent exists on the reflecting telescope as such.

If the urachus remains completely open, it is known as a patent urachus. This type of abnormality makes up 50% of all urachal anomalies.
The discovery of RDX dates from 1898 when Georg Friedrich Henning obtained a German patent (patent No. 104280) for its manufacture, by nitrating hexamethylenetetramine.[2] In this patent, its properties as an explosive were at length described, as well as its possible use as a medical compound mentioned. Research and development were not published further until G. C. V. Herz obtained a British patent in 1921 and a U.S. patent in 1922, for its manufacture by nitrating hexamethylenetetramine.[2] Later in the 1920s RDX was produced by the direct nitration of hexamine. RDX was used by both sides in World War II.

This statement likely indicates that the vertebral arteries are open, with good blood flow traveling in the typical direction without any narrowing or blockages present. The term "codominant" suggests that both sides of the vertebral arteries are contributing equally to blood supply in the brain.
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.
Patent revocation is the removal of patent protection from an invention.
