Zipf’s law and the distribution of patents among applicants - A Measure of Science

Shaun Hendy Nov 17, 2009

One of the interesting things we can do with the OECD patent database is look at how those patents are distributed among applicants. The applicant for a patent is often the organisation or company that employs the inventors rather than the inventors themselves. By looking at the distribution of patents among applicants we are looking at the size distribution … Read More

How many Aucklanders does it take to file a patent? - A Measure of Science

Shaun Hendy Oct 12, 2009

New Zealand’s patent output is horrible by OECD standards. On a per person basis, the OECD produces four times as many triadic patents (inventions that are patented in the big three economies: the US, Japan and Europe) as New Zealand. Finland produces nearly ten times as many. Our poor performance in patenting is one of the reasons we … Read More

Networks of inventors - A Measure of Science

Shaun Hendy Sep 28, 2009

Over the last six months I’ve been studying an OECD patent database with a research assistant, Catriona Sissons. The goal of our project is to study the economic geography of innovation in a quantitative manner. One of the things we have investigated is whether collaborative networks form between inventors through co-patenting. To find co-patents between inventors we use European Patent … Read More

A measure of science - A Measure of Science

Shaun Hendy Sep 26, 2009

As a theoretical physicist and applied mathematician, I’m interested in using numbers to describe all sorts of phenomena. And as a researcher in the MacDiarmid Institute, I’m also interested in innovation. So for me, it’s natural to try to study innovation quantitatively. One of the goals of this blog will be to look at science innovation using tools developed … Read More
