Despite recent criticism of the U.S. Patent and Trademark Office, including sharp words from Research In Motion, a co-founder of Visto says <A HREF="http://www.infoworld.com/article/06/03/16/76534_HNrimcompetitor_1.html">the patent office has been a great success.</A> RIM placed an advertisement in several newspapers this week saying the patent system is in need of change. While he contends that there's always room for improvement, Daniel Mendez, Visto co-founder and chief strategy officer, defends the patent office. "At any point in time people look at [the patent office] and say it's broken, it's a disaster, it needs to be revamped, but if you judge by the results, they're fantastic," he said. The U.S. patent office for around 200 years has presided over more innovation than any other country within the same time frame, he said.
