My focus

As a member of the Trial Bar, a USPTO-registered patent attorney, and a former consultant, I am an advocate and trusted business advisor for my clients. I work with clients in a range of industries when they are developing new products or entering new markets in IP-intensive areas, when they are acquiring and monetizing IP portfolios, and when they need to resolve disputes in an expeditious and cost-effective manner.

IP Acquisition, Licensing, and Enforcement

My practice is primarily focused on helping clients acquire and monetize IP assets and resolve IP disputes through licensing and litigation. I represent both plaintiffs and defendants in disputes involving a broad range of technologies, including networking, semiconductors, computer processors, wireless communication, and optics. I also have significant experience advising companies on IP and product strategy.

I combine my engineering and consulting backgrounds with my legal experience to gain a complete understanding of the business, technology, and legal issues my clients face. My engineering experience allows me to deeply understand the technology at issue so I can effectively advocate for my clients by explaining complex technological concepts to adversaries, judges, and juries in an understandable way. One of the greatest compliments I have received from a client was, “[our company] has its choice of any number of incredibly talented IP lawyers. But what sets Dan apart is that he listens to us. He understands and cares about our business, our products, and our technology."

I have litigated patent disputes before the Patent Trial and Appeals Board (PTAB), the International Trade Commission (ITC), and district courts across the country. In my appellate practice, I have served as counsel of record in patent cases before the U.S. Supreme Court and the U.S. Court of Appeals for the Federal Circuit.

Representative experience

• Representing multiple companies in connection with the acquisition, licensing, and enforcement of valuable patent portfolios related to networking, semiconductor, computer processor, wireless communication, and optical technologies.
• Represented one of the world’s largest LED manufacturers, as both plaintiff and defendant, in multiple patent cases related to semiconductor technologies before the PTAB and multiple district courts.
• Represented electrical and networking infrastructure manufacturer Panduit, as both plaintiff and defendant, in multiple patent suits related to fiber optic networking technology before the PTAB, multiple district courts, ITC, and Federal Circuit.
• Served as counsel of record representing Licensing Executives Society (USA and Canada), Inc. as amicus curiae in multiple precedent-setting patent cases before the Supreme Court and the Federal Circuit.

Looking ahead

IP transactions and monetization will continue to increase for at least two reasons. First, the stigma that once precluded large companies from selling their portfolios to monetization entities has disappeared. Second, companies with large portfolios will look to divest IP in non-core technologies to generate cash as macroeconomic conditions worsen.
