While the United States continues to lead in patents, other nations have encroached on the U.S. lead. In 2009, 51 percent of patents issued in the United States were awarded to non-U.S. companies. Only four of the top ten companies receiving U.S. patents in 2009 were based in the United States. In fact, nearly 60 percent of the patents filed with the U.S. Patent and Trademark Office (PTO) in the field of information technology now originate in Asia. This underscores the importance of overcoming complacency in the United States. Countries we used to think of as developing are in fact formidable competitors in many cases. The United States needs to start picking up the pace the catch those countries that are ahead and looking over its shoulder to see how quickly the competition is catching up.
