I just received my 150th issued US patent.

That kind of landmark tends to trigger a look back.

My first patent was number 6,756,879 and my 150th was patent number 9,166,974 — meaning 2.41 million patents issued between my first and my 150th. To get a sense of the accelerated rate of innovation in recent years, it is worth pointing out that more than 25% of all US patents ever issued have issued in the mere 11 years that passed since my first one issued in 2004.
