History in Brief
Prior to the year 1790, some of the States or provincial governments granted to inventors patents or exclusive privileges for their inventions.
By Act of Congress Approved April 10th, 1790, the first American patent system was founded. Under this Act the Secretary of State, the Secretary of War and the Attorney General, or any two of them constituted a tribunal to pass upon the patentability of the invention for which a patent was solicited. This Act was repealed February 1st, 1793; under this new Act the Secretary of State received the petition and caused the letters patent to be made out, which letters patent were examined by the Attorney General and signed by the President.
The Patent Office was established by Act of Congress, approved July 4, 1836, and attached to the State Department.
The Interior Department was created March 3, 1849, at which date the Patent Office was transferred from the State Department to it.
On the 28th day of April 1810, Congress made an appropriation of $20,000 for the erection or purchase of a suitable building for the accommodation of the General Post Office, and the "Office of the Keeper of the Patents". A building for the purposes named in the Act was purchased; the building was originally intended for a hotel, and situated on the Northwest Corner of 7th, and E Sts., N.W., site now occupied by the Post Office Department.
On March 7th, 1812, a further appropriation of $9,500 was made for the repair of said building; and during that year the Patent Office which was located in the War Department building, was removed to this building, where it remained until destroyed by fire, December 25th [sic], 1836.
The Patent Office then took rooms in the City Hall, and continued there until the spring of 1840.
The foundation of the south wing of the present Patent Office building was laid in the fall of 1836, was completed and occupied, in the spring of 1840, and cost $442,011.65. The east wing was commenced in 1849, and finished in 1852, and cost $600,000. The west wing was begun in 1852, and completed in 1856, at a cost of $750,000. The north wing, which completed this grand structure, was commenced in 1856, and finished in 1867, and cost $575,000.
Up to the year 1877, there had been expended upon the construction, repair and furniture of the Patent Office, the sum of $3,000,000. The North and West Halls of Model Room with 166 Model Cases and 124,000 Models were destroyed by fire September 24th, 1877
The North Hall, as it now is, was finished and re-occupied in 1881. The South Hall of Model Room was not damaged by the fire, but was re-modeled, which work was commenced May 1883, and the Hall re-occupied May 1885.
The system of numbering patents commenced July 28th, 1836; prior to that date, 9,957, patents were granted.
The whole number of patents issued from July 28th, 1836, to October 14th, 1890, inclusive, are as follows: --
Patents 438,596
Designs 20,207 (First in 1843)
Trade Marks 18,537 (First in 1870)
Labels 6,347 (First in 1874)
Reissues 11,117 (First in 1838)
Prior to July 28, 1836 9,957
________
504,761
About 2,700 of these patents were granted to women; the first bearing the date of May 5th, 1809.

Patents in Brief
A patent is granted for 17 years, to any person (citizen or alien, or even a minor) who is the first inventor of any new and useful art, machine, manufacture, or composition of matter. Cost: Government application fee, $15. A second Government fee of $20 has to be paid within six months of allowance. Models are very seldom required. Application must be made within two years of first sale or public use.
Caveats entitle the caveator for one year to notice of any interfering application, but are of little use otherwise. Cost: Government fee, $10.
Design patents are granted for 3 1/2, 7 or 14 years, at a cost of $10, $15, or $30 according to term.
A reissue of a defective patent may be obtained, if applied for within a reasonable time after the issue of the original patent. Cost: Government fee, $30. A reissue expires with the original patent.
An extension of a patent can only now be had by a special Act of Congress, which is very hard to obtain.
Trade-Marks are registered for 30 years. Cost: Government fee, $25.
Labels may be registered for 28 years. Cost: Government fee, $6.
