Cost of International Patents
How much do international patents cost? What does it cost for worldwide patent rights?

$160,000 to $330,000.  GAO estimate of the cost for a small business to extend a relatively simple U.S. patent to nine other countries.  “The GAO [General Accountability Office] estimates that it costs a small business about $10,000 to obtain and maintain a relatively simple patent in the United States.  Extending this patent to nine other countries could cost $160,000 to $330,000, according to the GAO.”   (Kent Hover, Washington Bureau Chief, “GAO: Cost of foreign patents is too high for small businesses,” Sacramento Business Journal, Friday, August 30, 2002)

$100,000 or more.  Potential cost to obtain worldwide patent rights.  “Getting even a simple patent approved -- a process known as ‘prosecuting’ the patent application -- can cost up to $10,000 domestically and $100,000 or more for worldwide rights…”  (Jeffrey Labovitz, licensing office acting director, University of California at San Francisco, quoted in Chris Rauber, “Dr. Strange Glove,” San Francisco Business Times, December 5, 1997)

$10,000 to $100,000.  Range of costs for international patents. “Simply filing patents can be a costly and time-consuming process, making it imperative for small companies to be selective about what patents they file.  [The] financial considerations may make companies be selective about what they are protecting, which can be a good thing for the industry. [Filing] patents internationally can cost a company anywhere from $10,000 to $100,000.”  (Sue Marek, “Healing the Patent Process”, Wireless Week, August, 15, 2005 citing information provided by Kimberly Chotkowski, senior patent attorney with InterDigital Communications Corporation, King of Prussia, PA, 610-878-7800)
