Our Areas of Practice
We are a full-spectrum law firm for innovative companies – especially in life sciences, SaaS, climate tech, digital media, consumer, web3, and AI.
Corporate and Transactional
We can handle all of your commercial contracts, financings, M&A, TOS, data privacy, license agreements, employment agreements, leases, MSAs, SOWs, SLAs, etc. If it’s an agreement, we can help.
We provide either outside counsel support – or supplemental in-house support. Or both.
The MainStreet team has decades of experience in GC and senior in-house counsel roles – so we can step in and fill any gaps or vacancies, and even help manage your outside counsel for you.
We offer discounted and monthly fixed fee structures for in-house support – tell us what you need, and we’ll make it happen.
Intellectual Property
You’ve worked hard to come up with an awesome brand and amazing innovations. Make sure they’re protected the right way. We have decades of experience in intellectual property — in virtually every area of technology — and we can handle your patent and trademark applications and license agreements for 50-62% less than at large firms.
With deep experience in patent, copyright, and trademark disputes, our team can also handle any IP litigation or other issues you may face. We’ve won numerous major victories before the U.S. Patent & Trademark Office (USPTO), federal courts across the country, and at the International Trade Commission (ITC).
Litigation and Disputes
Led by nationally renowned litigator Tristan Snell, our litigation team has won victories against the toughest opponents, on the biggest cases, with millions or even billions at stake. We understand that the goal of handling a dispute is not to win an argument – it’s to win the best outcome for you as a client, whether that means winning in court or reaching a positive settlement. We handle select cases on a contingency fee basis, and our hourly rates are 46-75% lower than at comparable firms.
Our cases include all forms of litigation, appeals, arbitration, and mediation, as well as demand letters and settlement negotiations — covering everything from commercial disputes to patent litigation. Whether it’s a small breach of contract matter or a headline-grabbing case, we’ve seen it all, and we know what it takes to win.
About Us
Tristan Snell
Tristan’s work includes successes in some of the most high-profile legal matters of the century – including the prosecution of Trump University (leading to a $25 million settlement), the Broadcom v. Qualcomm patent litigation (the largest in US history at the time, with a $1.2 billion victory for Broadcom), and landmark deals with Chase, Wells Fargo, and Walmart, among others.
He has represented many of the biggest technology-based companies, including Johnson & Johnson, Broadcom, Yahoo, and Smith & Nephew, giving him a deep understanding of the special challenges facing high-innovation businesses.
He has also represented hundreds of startups, as well as early-stage venture funds, and has also started four businesses of his own and served as a tech company CEO, COO, General Counsel, and Product Manager.
Tristan graduated from Princeton University, where he was elected to Phi Beta Kappa. He received his law degree from the University of Virginia, where he was an editor of the Virginia Law Review. Tristan worked in the renowned intellectual property, appellate, and venture practices at WilmerHale, where he also worked on the Boumediene v. Bush team that won the first habeas writs for detainees at Guantanamo Bay. He served as a law clerk to the Hon. Eric N. Vitaliano, U.S. District Court Judge for the Eastern District of New York, and as Assistant Attorney General for the State of New York as a civil prosecutor and investigator in consumer protection.
Tristan is also a nationally recognized legal commentator, featured on MSNBC, CNN, and NPR and in the Washington Post and Wall Street Journal, among dozens of other outlets. He lives in New York City and enjoys tennis and hiking, though not quite as often as he’d like.
