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 the filing for a patent and the issuing of the patent (i.e., a patent's "pendency") is about 32 months, patent counts displayed in the tables that distribute counts by year of patent application are incomplete for the years 2000 - 2008. This is because a significant number of the applications filed from 2000 - December 2008, which will ultimately become patents, were still pending in December 2008. Since they had not yet become patents as of December 2008 (i.e., the patents included in these tables are limited to those patents that were granted from 1969 through December 2008), they are not counted in these tables.

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.

As of 12/31/2008, utility patent application data were approximately 98% complete for patent applications filed in calendar year 2000, 93% complete for calendar year 2001 filings, 90% complete for calendar year 2002 filings, 78% complete for calendar year 2003 filings, 60% complete for applications filed in 2004, 37% complete for applications filed in 2005, and 17% complete for applications filed in 2006. They were essentially complete for applications filed prior to calendar year 2000.
