Patent Litigation

Patent disputes place valuable technology, products, and market positions at risk. Successfully resolving those disputes requires more than knowledge of patent law. It requires litigators who can master complex technologies, develop a persuasive case strategy, and translate technical and legal issues into arguments that judges and juries can understand.

At Perilla Knox & Hildebrandt, our patent litigators represent patent owners and accused infringers in high-stakes disputes involving technologies across a broad range of industries. We handle patent litigation from initial case assessment through discovery, claim construction, expert proceedings, dispositive motions, trial, and appeal.

Our approach combines patent litigation experience with the technical depth of an intellectual property firm. We work closely with clients, inventors, engineers, and technical experts to understand the technology at issue, identify the arguments that matter, and build litigation strategies around our clients' business objectives.

Recognized patent litigation experience.

Our intellectual property practice has earned national recognition for its work on behalf of innovators and businesses. Perilla Knox & Hildebrandt has been named Tier 1 in Patent Law and Tier 1 in Intellectual Property Litigation and has been ranked among the 100 most active law firms in patent litigation in the United States.

Those distinctions reflect a practice built around intellectual property. Our attorneys understand patents from both sides of the equation—from how patent applications are prepared, prosecuted, and strategically developed to how patent claims are construed, challenged, enforced, and defended in litigation.

That perspective can be particularly valuable when a dispute turns on the prosecution history, prior art, claim scope, infringement theories, or questions concerning patent validity and enforceability.

Technical understanding. Litigation strategy.

Patent cases often turn on highly technical details. Our attorneys work directly with engineers, scientists, inventors, and expert witnesses to develop a deep understanding of the accused products and patented technologies.

We represent clients in disputes involving software and computer technologies, artificial intelligence and machine learning, telecommunications, electronics, semiconductors, mechanical and electromechanical systems, medical technologies, manufacturing, and consumer products, among other technologies.

We combine that technical understanding with focused litigation strategy across issues including patent infringement and noninfringement, claim construction, invalidity, prior art, damages, willfulness, injunctive relief, and other issues affecting the enforcement and defense of patent rights.

From pre-suit analysis through trial.

Effective patent litigation strategy often begins well before a complaint is filed. We counsel clients on potential infringement disputes, evaluate patent portfolios and accused products, analyze litigation risk, and help businesses determine whether—and how—to pursue or respond to a patent claim.

When litigation becomes necessary, we represent clients through the full lifecycle of the dispute, including pre-suit investigation, pleadings, discovery, depositions, claim construction, expert discovery, summary judgment, mediation and settlement, trial, and post-trial proceedings. We also coordinate litigation strategy with related proceedings before the U.S. Patent and Trademark Office and Patent Trial and Appeal Board (PTAB) when appropriate.

Our Clients.

We represent patent owners and accused infringers, including emerging technology companies, established businesses, manufacturers, entrepreneurs, and multinational corporations. Whether a client is enforcing patents covering technology central to its business or defending a product against allegations of infringement, our objective is the same: develop a strategy grounded in the technology, the law, and the client's commercial priorities.

We recognize that patent litigation is ultimately a business problem as well as a legal one. Our attorneys work closely with clients to evaluate risk, cost, competitive considerations, and potential outcomes throughout a dispute so that litigation strategy remains aligned with the client's broader objectives.
