Selected Virtual Currency Patent Applications
Virtual Currency Patents Index May 2015 — Definitions
As we use it here, “virtual currencies” include digital currencies, cryptocurrencies and other innovative electronic currencies. Virtual currencies may include Bitcoin, Darkcoin, Dogecoin, Litecoin, Mastercoin, Namecoin, NXT, Peercoin, Ripple, etc.
We limit the Virtual Currency Patent Index to patents and patent applications that are substantially related to virtual currencies. Patent records that make only a passing reference to a virtual currency are generally not included. Please let us know if we have missed any important patents.
The Virtual Currency Patent Index tracks patent applications and patents that have been published or granted by the U.S. Patent and Trademark Office. Although most applications are published, a small percentage (about 7% nation wide) are not published for various reasons. Patent applications are generally published 18 months after the first priority date of the application. Published applications have not necessarily been examined and some applications will be abandoned after publication. Once an application is examined and approved and all fees and formalities have been satisfied, the Patent Office grants a patent.
