Professional Biography
Dean has a passion for litigating complex intellectual property cases and protecting IP assets.
“I founded Amburn Law, now The Pure.Law Firm, as a different kind of law firm – where we focus on providing exemplary and ethical legal services to our clients instead of requiring billable hour quotas, as commonly practiced at big firms. We hire and work with professionals of quality character with excellent legal skills, and we develop effective systems to better litigate cases and manage our IP practice. As a result, you win, and we win.”
