Our Commercial Litigation Practice Areas:

Contract Disputes: We litigate breaches of vendor contracts, partnership agreements, service agreements, employment contracts, and complex commercial arrangements. From multi-million dollar deals gone wrong to disputes over non-compete agreements, we bring strategic thinking and aggressive advocacy to protect your interests.

Partnership & Shareholder Disputes: Conflicts between business partners, shareholders, and company executives can threaten the survival of successful enterprises. We represent founders in ownership disputes, handle derivative actions, litigate fiduciary duty breaches, and resolve conflicts over profit distribution and corporate governance.

Class Actions & Mass Litigation: Our attorneys have experience on both sides of class action litigation, representing plaintiffs in consumer fraud and securities cases while also defending corporations against class certification and through trial. We understand the unique dynamics of aggregate litigation and develop strategies tailored to achieve the best outcomes.

Intellectual Property Litigation: We litigate patent infringement, trademark disputes, trade secret misappropriation, and copyright violations in federal courts. Our IP practice includes both offensive and defensive strategies for protecting your innovations and brand.

Business Torts & Fraud Claims: From tortious interference and unfair competition to fraud and misrepresentation claims, we aggressively pursue or defend against business tort allegations. We also handle RICO claims and complex fraud litigation.

Real Estate & Construction Litigation: Our practice includes commercial lease disputes, construction defect claims, real estate contract breaches, and land use conflicts.

28 USC 1782 DIscovery Litigation: We help foreign parties obtain discovery in the United States through the use of what is known as “1782 proceedings”. See our blog post for a primer on what a 1782 proceeding is.

Unlike firms that focus exclusively on one side of the "v," Dynamis attorneys represent both plaintiffs and defendants, giving us comprehensive perspective on litigation strategy, settlement dynamics, and what actually moves cases toward favorable resolutions. We understand that litigation is a tool to achieve business objectives—not an end in itself. Our approach combines sophisticated legal advocacy with practical business judgment to resolve disputes efficiently while protecting your reputation and bottom line.

In addition, many business disputes involve allegations of fraud or securities violations requiring white-collar defense expertise. We also handle cryptocurrency and blockchain business disputes, including partnership conflicts, token distribution disagreements, and DeFi protocol litigation.
