He was never a valuable source for anything [...]
You're entitled to your opinion on this, but it is not shared by some very credible people in the intellectual property universe:
- Managing Intellectual Property (ManagingIP) magazine has put me on its annual list of the top 50 most influential people in IP five times so far (2005, 2006, 2012, 2013, 2014).
- IAM (Intellectual Asset Management) magazine named me one of the IP personalities of 2011 (and had me on some other ranking that I can't find at the moment).
- Canadian IP lawyer Barry Sookman conducted some research on the leading IP and tech law blogs. According to his analysis (published in early 2013), my FOSS Patents blog was the #3 U.S. patent law blog at the time.
- I have received invitations to speak at conferences organized by universities and around the globe (in the U.S., literally from California to New York) and at commercial conferences in the U.S., different European countries, different Asian countries, and New Zealand. Only for logistical reasons I have had to politely decline except for invitations in my home region. I have spoken at the renowned Max Planck Institute for IP and Competition Law in Munich, at the Munich University of Technology (three times already), and the University of Bayreuth, where I shared a panel with a judge from the patent-specialized division of Germany's equivalent of the U.S. Supreme Court (see page 2 of the conference program), who is also widely expected to become one of the top-ranking judges of Europe's future Unified Patent Court. This incredibly well-respected patent judge and I both addressed the same topic, from our different vantage points, and had a panel discussion with questions from the audience and our moderator, a Switzerland-based patent law professor.
- Professor Thomas Cotter (University of Minnesota), an expert in comparative patent remedies (he travels the world to research differences between national patent laws), wrote this post about the significance of FOSS Patents earlier this year. Professor Cotter's independence is underscored by the fact that he has in recent years signed amicus curiae briefs supporting a core Apple position (on FRAND) and opposing a core Apple position (on design patent remedies).
- I could give more examples, but suffice it to say that any of the above references easily outweighs whatever a blog like Groklaw may have written about me over the years.
