Considerations Regarding Patents As Distributed By Year of Application (Table 2)

DATA FOR THOSE APPLICATIONS WHICH WERE FILED BUT NEVER ISSUED (ROUGHLY 25% OF TOTAL FILINGS) ARE NOT INCLUDED IN THIS TABLE.

Since the average time period between filing for a patent and the issuing of the patent (i.e., the patent's "pendency") is now about 24 months (for utility patents), the patent grant data, as distributed by year of application, are incomplete for the most recent years that are displayed in this table. This is because a significant number of those applications which ultimately would become patents were still pending as of these most recent years that are displayed in this table.

Patented application data are of significant value since the date an application was filed more accurately reflects when the technology was developed. Additionally, fluctuations in data based on application date are much more likely to reflect changes in technological activity since, for the most part, such fluctuations would be immune from changes in U.S. Patent and Trademark Office (USPTO) processing such as occurred in years such as 1986 when the USPTO issued fewer patents than would have normally been expected due to a lack of funds to print patents. Note that a patent's "pendency" can be quite variable from one patent to another, thereby affecting the date of patent grant. Such variation in pendency is determined by many factors, including PTO workload (which varies between technologies), budget and manpower levels, patent printing schedules, etc. Please note that types of patent documents such as design patents, plant patents, reissue patents, statutory invention registrations, and defensive publications may have average pendency periods that differ somewhat from the pendency period for utility patents.

In this table, utility patent grant data, as distributed by year of application are approximately 93% complete for utility patent applications filed in 1999, 84% complete for applications filed in 2000, 66 percent complete for applications filed in 2001 and 44 percent complete for applications filed in 2002; data are essentially complete for utility patent applications filed prior to 1999.
