Perilla Knox & Hildebrandt

Intellectual property counsel. Built around your business.

Founded in 2022 by three attorneys, Perilla Knox & Hildebrandt has grown to a team of more than 40 professionals, including practitioners, paralegals, managers, docketing personnel, and accounting staff. That growth reflects our commitment to building the legal, technical, and operational capabilities needed to support our clients.

We help innovators protect their ideas, strengthen their brands, and defend their competitive position. Our team combines technical knowledge, legal experience, and practical business judgment with the personal attention and responsiveness of a focused intellectual property firm. We represent emerging businesses, established companies, and universities developing the technologies and ideas that shape their industries.

We begin by understanding what matters to your business: where you are today, what you are building, and how intellectual property can support your goals. That understanding guides our advice, from securing protection for a new invention to managing a growing portfolio or resolving a consequential dispute.

Experience across the life of your intellectual property

Our practice spans patent preparation and prosecution, trademarks, copyrights, trade secrets, licensing, portfolio management, and intellectual property litigation. We also represent clients in post-grant proceedings before the U.S. Patent and Trademark Office. This breadth allows us to consider how decisions made today may affect enforcement, commercial opportunities, and long-term portfolio value. Explore our practice.

Whether we are working alongside an in-house legal team or serving as a growing company’s primary IP counsel, our focus is consistent: clear advice, thoughtful strategy, and work aligned with the client’s business objectives.

Innovation in how we work

We bring an inventive mindset to the way we deliver legal services.

PKH has made substantial investments in building internal systems that help our paralegals and practitioners work more efficiently. These systems are designed to streamline routine tasks, reduce repetitive administrative work, and support coordination across our team—giving our professionals more time to focus on substantive work and client needs.

That investment serves a practical purpose: controlling the cost of delivering high-quality legal services. By improving how work gets done, we seek to keep our rates competitive and deliver greater value to our clients. Efficiency is an ongoing commitment, reflected in how we build our systems, organize our work, and support our people.
