David Kleiman has been my attorney for almost 10 years, representing me in my efforts to create and develop certain intellectual property involving several patents and a trademark. During that time, he has been able to explain some very complex legal and technical rules in a way that I could understand. He always kept me informed and advised different alternatives, demonstrating that he truly was helping me to obtain my objectives. His fees were reasonable and access to him was never a problem. I would definitely recommend David to anyone seeking counsel of a patent attorney.
