Professor David Hricik


I am licensed to practice law in Texas and Georgia. For 30 years, starting with about a decade at Baker Botts, I have focused on patent practice and legal ethics, including legal malpractice. In addition to litigating patent and other IP cases, I have represented clients accused of misconduct by the Office of Enrollment and Discipline of the United States Patent & Trademark Office, served as an expert for lawyers defending charges by the OED, and even served as an expert in patent prosecution practice and ethics for the OED itself. I have also served as an expert witness in cases involving inequitable conduct, patent prosecution malpractice, conflicts of interest in patent prosecution and litigation, and general ethical issues in the context of patents and general commercial practice. I consult with firms and lawyers seekng to navigate the issues that patent practice presents, provide in-house CLEs, and provide other services related to risk management.

In 2012-13, I set a record (I think) for serving as the oldest clerk to a judge at the United States Court of Appeals for the Federal Circuit when I took leave from teaching and I was honored to serve as a clerk for then-Chief Judge Randall R. Rader. Upon completing my clerkship and returning to my professorship at Mercer, I also became Of Counsel to Taylor, English, Duma, LLP, where I have led cases involving legal malpractice, and assisted in patent litigation, trademark litigation, and general commercial litigation.

I wrote the book on ethical issues in patent litigation, and co-authored the book on ethical issues in patent prosecution, blog at patentlyo, and write and speak a dozen times a year on ethics and IP law. Links to resourcesa are below, and several my articles are available on
