Global Patent Quality Statistics & Investment Analysis

Patent Quality Statistics

If patents represent the best innovation, then a strong measure of innovation at the corporate and national levels is the measure of patent quality at the corporate and national levels. What follows below are: first, our comprehensive statistics and measurements of U.S. patent quality and valuations; second, interactive graphs of this data; third, patent statistics from government agencies around the world. This data can also be used for stock market analysis, which we are incorporating into stock market recommendations for companies with significant patent portfolios.

Statistics on U.S. and Global Patent Quality


Interactive graphs of weekly/yearly patent quality/finance data

While the data in the above spreadsheets are quite powerful, it is visually boring. We have prepared a series of interactive graphs (using Javascript) to better reveal patent quality trends. Feel free to request other types of patent quality graphs we can add to the Web site, and please send us any improvements you can make to our Javascripts.

Patent Value/Royalty/Licensing Analysis tools

For those with one or more quality patents, an important economic question is that of determining the financial value of a patent portfolio. What follows is some links to free tools on the Internet to help with such assessments.


Inadequate (Inter)National Government Patent Statistics

For over 30 years, patent offices, government agencies and patent lawyer associations around the world have measured patent quality simplistically, if it all, which makes it impossible to measure true patent quality, innovation quality and the economic benefits of patents and innovation to their countries or clients. None of their statistics are easily usable by themselves or the public.



Faulty Economic Critiques of the Patent System

Some "economists" try to attack the patent system by arguing that there is little correlation between GDP/productivity and some of the aggregrate patent statistics. The first problem with such attacks is that productivity itself is a suspect economic quantity - see, for example, a blog and hilarious/informative video criticizing Keynesian GDP/productivity measures, Consuming Our Way to Prosperity is Macro Folly, and more formally, a Janaury 2013 Chicago Fed Letter article reporting on the general death of productivity growth across the entire economy (not just the patent-related sector): Where has all the productivity growth gone?.

So when you hear an "economist" arguing "We (probably) don't need patents because their correlation with productivity is .....", unless you are drunk, find someone else to listen to. Such arguments are based on the idealistic economic models they concoct that are based on a poor understanding of technology, patent system dynamics, and real-world business economics. Some of these "economists" include Bessen, Meurer, Boldrin, Levine:
