    Jonathan has been a good friend of mine for many years now, we both share a passion for the law as well as classical music. I have found Jonathan to be quite knowledgable with regard to intellectual property issues, as well as a patient and thoughtful listener. In addition to being a superb intellectual property lawyer, Jonathan is also an accomplished trumpet player, a rare and extraordinary combination. I endorse Jonathan without hesitation.
