Litigation

We defend some of the nation’s largest media and internet companies against class actions brought under a variety of state and federal statutes. We have defended clients in class actions brought under federal statutes such as the Wiretap Act, the Stored Communications Act, the Video Privacy Protection Act, the Computer Fraud and Abuse Act, and the Telephone Consumer Protection Act, and state statutes such as Michigan’s Video Rental Privacy Act, California’s Shine the Light Law, the California Invasion of Privacy Act, and numerous state unfair competition laws.

Although we pride ourselves on giving our clients sound judgment that will allow them to achieve their objectives without incurring liability, sometimes litigation is inevitable. We’re more than ready. Our founder secured the first ever guilty jury verdict in an Economic Espionage Act case involving theft of trade secrets by a foreign entity. We won a precedent setting victory on a DMCA claim involving the circumvention of a client’s in-game cheat detection software. We have successfully defended class actions alleging Computer Fraud & Abuse Act claims, Electronic Communications Privacy Act violations, mobile phone spam, app data practices, data security breaches, fantasy sports, bid-rigging in the sale of sponsored online advertising, and a variety of other unfair practices claims. We’ve successfully defended clients by obtaining immunity under Section 230 of the Communications Decency Act.

We are also proactive. We have prosecuted, defended and settled copyright, DMCA, CFAA, ECPA and secured preliminary injunctive relief, executed civil seizure orders, and other special relief.

Our Litigation Philosophy is Simple

We set a clear objective and then build a strategy with a singular focus. Every action we pursue has an identifiable purpose that serves the client’s ultimate objective. We’re efficient and creative. We have handled cases in state and federal courts in California, New York, Illinois, DC, Wisconsin, Maryland, Missouri, Arizona, Connecticut, and Georgia. We have also served as lead counsel in federal appeals in the Third, Fifth, Seventh, Ninth, Tenth, and Eleventh Circuits. We are hired by clients from coast-to-coast because of our excellent results.

Billing That Works the Way You Do

We aren’t a typical law firm and we don’t bill like one either. We customize our billing practices to fit each client’s needs—building flexibility, transparency, and trust into every engagement. Whether through flat fees, monthly retainers, or competitive hourly rates, we focus on delivering clear value and predictable results, so you can plan confidently and stay focused on what matters most.

  • <h5>MONTHLY RETAINERS</h5>
    1

    MONTHLY RETAINERS

    We handle all of the legal work in a given area or subject matter for a monthly retainer, which we can adjust upward or downward as the work ebbs and flows.

  • <h5>FLAT/PROJECT FEES</h5>
    2

    FLAT/PROJECT FEES

    Under this model, we take the risk that we have underestimated the time that needs to be spent. If it takes longer, you still don’t pay more. If we are very efficient, we get the benefit of our efficiency.

  • <h5>COMPETITIVE HOURLY RATES</h5>
    3

    COMPETITIVE HOURLY RATES

    Because we work collectively to solve your problems, a majority of our attorneys are available for the same hourly rate, except our Fellows and Junior Attorneys who bill at lower rates and are perfect for tasks you don’t want to pay a legal veteran to do.
