IP, Technology & Science Litigation
Notable Representations, Key Contacts
We are experienced counselors who will work with you to resolve your thorniest disputes as efficiently as possible, often with creative business solutions that are accretive to your business. And we are elite trial lawyers recognized by the American College of Trial Lawyers, Chambers, and numerous other organizations as the best of breed so, when trial cannot be avoided, we are ready to fight, and win, in even the most hostile venues. We work with plaintiffs and defendants alike, and have deep experience in the most frequently used district courts for IP, technology, and life sciences disputes, the ITC, the PTAB, the Federal Circuit, and numerous state courts across the country. Finally, we seek long-term relationships with clients, not one-off cases, and will partner with you to avoid surprises, provide rational and predictable budgets, and ensure tireless client service and commitment to your matters.
Our Trial-Focused Approach
We are trial-focused from the start of every case.
- We seek to identify early on what “really matters” and focus on these issues from the onset.
- We master the technology and science in our cases, then build cohesive, simple, and compelling storylines that appeal to fairness and common sense.
- We resist bogging down in details that distract from winning themes and waste money.
- And we bring to bear a deep reservoir of experience to better cultivate discovery and identify and maximize dispositive issues that can be brought early to a judge with the aim of winning our cases with a reduced investment.
We use lean teams to improve efficiency and cost-effectiveness for our clients, and because we believe it helps us win our cases. By avoiding bloated teams, all of our team members can obtain a holistic perspective on our cases and avoid the mistakes we often see others make, such as pursuing conventional theories and discovery that are ultimately in tension with the path to victory. And we eschew the parachute model – our senior lawyers will be dedicated to your case from start-to-finish.
As our track record shows, our approach pays dividends for every case. When we appear for you at any stage, it sends a strong signal to your opponent that you are committed to winning your case, which often leads to quicker and better settlements. When the goal is to achieve a favorable resolution as early as possible, we have an unparalleled record of winning cases on summary judgment and on motions to dismiss. And, with dozens of trials under our belt involving patent, trade secret, copyright, trademark, fraud, licensing, contract, interference, unfair competition, and other related causes of action, we are well-known and respected by our adversaries as fierce and effective trial lawyers.
