About Us

Knobbe Martens is an agent of innovation, providing clients worldwide with forward-focused intellectual property and technology law service and representation. We are one of the largest and fastest-growing IP law firms, with over 275 attorneys and scientists representing the complete spectrum of technologies and IP practice areas.

We combine unmatched technical and litigation expertise to deliver superior results in both transactional and contested matters, for both cutting-edge start-ups and established Fortune 500 companies. Our work spans fields ranging from physics to pharmaceuticals and entertainment to engineering.

But perhaps more impressive than our scope is our skill. We are established leaders in our fields—scientists, engineers and thinkers who blend deep educational and technical knowledge with a strategic focus gleaned from our real-world business experience. 

We know your issues. Your pressures. And should the need arise, we know how to aggressively protect the assets that give your business its competitive edge—with extensive experience and intimate knowledge of domestic and international judicial systems.

Whatever our role, our goal is simple: to advance and protect those whose innovations propel the world forward.

Principles and Values

Integrity. Honesty. Passion. To us, these are more than mere words. They’re a promise, a pledge we make to always provide the highest level of professional, ethical representation. To never cut a corner nor accept a compromise. Our clients demand—and deserve—no less.

A Culture of Collaboration

We love competition, just not with each other. We foster a collegial, cooperative atmosphere where every attorney works for the good of the firm, and by extension, for each of our clients. Our attorneys are not compensated to “own” clients, rather, they’re motivated to match clients with an attorney/scientist team custom-built to deliver success. It’s a model that puts our clients’ interests above our own. Which is exactly where they belong.

Strength Through Stability

Since 2000, our firm-wide attrition rate has been approximately 10%. This helps us create and maintain lasting relationships with each client, as well as a deep institutional understanding of their business. Our clients trust the people they called on yesterday will be here tomorrow. There’s no learning curve or revolving door, just a strong, stable team they can count on at any time…all the time.

People First

Our unique culture and corporate structure allow us to attract and retain some of the world’s top IP attorneys. Instead of reserving partnerships for a privileged few, we take a different approach: actively training our associates to assume leadership roles, and providing an environment where their abilities are fully utilized in the best interests of our clients.

Rankings & Recognition

We’ve found that if you focus on excellence, accolades usually follow. We’re proud to be so recognized by pundits and peers alike.
