A patent attorney's role is to add value to clients’ businesses in a tangible way. I enjoy leveraging what I’ve learned, both while working as a Patent Examiner for ten years, and as a practicing patent attorney, to assist inventors in obtaining a patent.

Working as a Patent Examiner has given me the unique ability to assess a patent application from the prospective of the Patent Examiner. Pairing these skills with my current practices as a patent attorney allows me to approach patent application drafting and patent prosecution in an inclusive manner by leveraging my knowledge of the manner in which a Patent Examiner thinks to advance the goals of our clients to obtain a quality patent in a timely and cost effective manner.

Attending law school in the evenings at the University of Baltimore while working full time as a Patent Examiner at the USPTO in Alexandria, Virginia was a challenge. It was during this time that I honed my time management skills, learning to balance a heavy case load at the USPTO with the challenges that are intrinsic to law school studies.

Nothing worthwhile comes easy... a worthy pursuit, for the right reasons, is more precious than gold.

The most important skill that a patent attorney could possess is communication – both written and oral. We have to be able to concisely communicate with our clients, who may be scientists, engineers, or business associates, to ascertain the fundamentals of their invention, and what they hope to achieve with their patent from a business prospective.

Challenge yourself to conquer more challenging tasks, but also embrace humility. Don’t ever believe you know it all. You’re always learning, and there will always be plenty to learn from colleagues and clients.
