Only 2,845 "X" series patents were reconstructed in the 1840's and are available today. Reissued "X" patents have an "RX" prefix. A fire at the Patent Office in 1836 destroyed most records of the "X" patents. Some 9,957 patents issued between 17 were retroactively assigned "X" series numbers in the order in which they were issued.

"B" was also used as a prefix for documents published in the Trial Voluntary Protest Program (TVPP) in the mid-1970's.(For design, plant, reissue patents, the Reexamination Certificate will include the normal designation letter - BD for design, BP for plant, etc.) The numeric portion of the number is the number of the patent to which the reexamination certificate refers. B - Re-examination Certificate, issued after a patent has issued and has been examined again by request of the patentee.AI - "Additional Improvement" patents, issued only between 18 - somewhat similar to today's "Continuation in Part" applications.Other patent office documents have letter prefixes before the number which indicate the kind of document: (10) Number: A utility patent will have a number here with no letter prefix (other than the "US" which denotes a US publication).

SIRs were introduced in 1985, replacing the earlier Defensive Publication program, and were abolished (effective in March 2013) by the 2011 America Invents Act. The SIR program was never used very much - as of September 2011, only 2,264 SIRs had been published in 26 years. Defensive Publications and SIRs do not give any rights to exclude others from making, using or selling, as would a patent. "Defensive Publication" or "Statutory Invention Registration" - a publication made for the defensive purpose of preventing others from getting patents.The Reissue Patent has been examined and issued again with modifications to the claims.

A complete list of these codes is available on this site. If any of the terms used in this explanation are unfamiliar, you will probably find them defined in our Patent Glossary. These numbers, called "INID Codes", are used universally on all printed patents around the world, so that you can identify the information elements on a patent even if you do not speak the language.
