What is the patent number of the reflecting telescope?
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. The Dobsonian mount is a popular alt azimuth mount for reflecting telescopes, created by John Dobson in the 1960s. He apparently never applied for a patent for this.
How is RDX used as a medicine?
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.

Patent urachus repair - series?
Normal anatomyThe urachus is a tube that connects the bladder to the umbilicus during fetal development. After birth, the urachus normally closes and becomes a ligament.IndicationsSurgery is recommended for a patent urachus that does not close after birth. There is some variablity in the degree of the defect. Sometimes, only the umbilical end of the urachus fails to close, generating a urachal sinus, which does not connect with the bladder, but simply eneters the skin for a short distance. These can usually be excised locally. If the entire urachus is patent all the way to the bladder, the urachus must be excised and the bladder closed.IncisionWhile the infant is deep asleep and pain-free (using general anesthesia), an incision is made in the lower abdomen, below the umbilicus.ProcedureThe urachus is located and removed from the umbilicus and the bladder. The bladder opening is repaired, and the incision is closed.AftercareThe outcome is usually excellent. The infant can be fed normally and should recover rapidly. A few days of hospitalization is all that is usually required.Reviewed ByReview Date: 09/03/2010David C.

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.
Is there any training on how to get a patent from the patent office?
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.
