The USPTO issued 55,488 patents in Q1, 11.3 percent more than the previous quarter and a 12 percent increase over the same period last year. In fact, this was the largest quarterly total in five years. The number of published applications was 77,520, a decline of 12.3 percent from the previous quarter. The global recession has had a negative impact on patent filings worldwide, with most patent offices reporting a decline in new applications over the past year. Since patent applications are published 18 months after filing, the number of published applications may continue to drop throughout 2010.
