The Firm Mission

Lief Parke LLP is committed to providing the highest caliber intellectual property litigation and counseling in the most rational and efficient manner possible. “Ingenuity and Integrity” are our hallmarks. Our clients are innovators and trail blazers—so are we. 

Our History and Philosophy Forward

Our firm is new, but built on a relationship spanning a quarter century. Our paths crossed at two separate firms. The first time was in 1995 at the storied New York IP boutique Hopgood Calimafde Kalil & Judlowe. Back then, Hopgood Calimafde was litigating patents covering Zantac®—then the world’s largest blockbuster medicine—and other critical inventions. The second time was in 2011 at another prestigious New York IP firm. And now we have come full circle and have founded our own firm—Lief Parke LLP.

Combined, we have 55 years of IP litigation and counseling experience—including patent, trademark, copyright, and trade secret cases in areas ranging from the pharmaceutical and biotech industries to the industrial equipment and medical products industries, among many others. We have tried many cases. We have won many cases. We understand science and law. 

We also bring a critical eye to how other law firms handle cases and bill clients. We believe in providing billing options beyond the increasingly outdated billable-hour model. Our approach involves a willingness to explore fixed fees, contingent fees, and success fees, or bespoke blends of those options, aimed at more appropriately responding to each client’s needs. We also will be relentless in trimming unnecessary infrastructure and overhead that contributes to the elevated costs at many firms, while maintaining the highest standards of excellence. Like our clients, innovation is at the core of what we do.

Truly effective lawyering involves listening intently to clients, identifying their individualized issues and needs, and providing legal solutions to advance their objectives. We would be honored to represent you, advocate for you, and help further your success.
