PATENT LITIGATION
SERVICES
Our nationally recognized patent litigation team has the experience and insight to help you navigate every step of the process. Whether you’re defending against a patent infringement claim or looking to enforce your own patent rights, we’re here to guide you with clarity, strategy, and confidence.
Some firms measure success in winning at trial. We do, too.
However, at Klarquist we place a higher value on winning before trial. Our clients do, too.
Patent litigation isn’t just complex—it’s high-stakes. That’s why companies choose Klarquist when facing a patent lawsuit. Our exclusive focus on intellectual property gives us the depth to see what others miss and the experience to act decisively. With decades of patent litigation success behind us, we build defense strategies that are not only comprehensive but built to win at every stage.
Patent litigation is also expensive. We recognize that being a defendant in patent litigation isn’t where you want to be. That’s why we focus on achieving early, decisive outcomes. Our goal in every case is simple: win—and win quickly. By resolving disputes efficiently, we help reduce your legal costs and maximize the value of your litigation success.
At Klarquist, we know that post-grant proceedings before the Patent Trial and Appeal Board (PTAB) offer a powerful, cost-effective path to eliminate weak vulnerable patents.
Our team combines deep technical fluency with procedural precision to challenge patent validity head-on. We craft petitions that expose vulnerabilities, present evidence that persuades, and coordinate seamlessly with parallel district court litigation.
The result? A proven track record of early, efficient wins that protect your business and bottom line.
Klarquist’ approach to IP litigation is both systematic and agile. We adopt a comprehensive litigation strategy within the first weeks of every new engagement and refine it continuously as the case evolves. This balance of structure and flexibility allows us to anticipate challenges, pivot quickly, and stay aligned with our clients’ goals.
We also tailor our litigation teams to fit the needs of each case. When a lean team is sufficient, we keep it focused and efficient. When a matter demands more resources, we scale up strategically. We don’t overstaff for appearances, we staff for impact.
Our comprehensive litigation strategy ensures that we are building the case for a favorable settlement or trial. Throughout the process, we rely on key internal systems and procedures that support our efforts as we apprise you of facts, schedules, and strategies. If we can’t win quickly, we are ready for trial, and you are positioned for the best possible outcome.

We don’t take every case—just the right ones.
Unlike many plaintiffs’ firms that pursue volume-based litigation, Klarquist is highly selective in the plaintiff cases that we take. We represent clients who are building real value through innovation, and we focus on protecting and defending that value with precision and integrity.
Klarquist is more than a litigation firm, we’re also patent builders. Our team understands how strong patents are crafted and how they’re challenged in court. This dual perspective allows us to anticipate attacks and develop enforcement strategies that hold up under pressure. Our litigators also work hand-in-hand with our patent prosecutors to ensure every case is built on a solid foundation, making us uniquely equipped to assert patents with confidence.
We focus our efforts where they matter most—on cases with clear merit and meaningful impact. Our litigation team works closely with our prosecution attorneys to ensure that the patents we enforce are built to withstand scrutiny. We’re selective about the cases we take on because we believe in the strength of the IP we represent and we know how to make that strength clear to judges, juries, and administrative panels.
Patent validity is often challenged in the Patent Trial and Appeal Board (PTAB), where the stakes are high and the timelines are tight. Klarquist has successfully defended patents in PTAB proceedings by combining technical fluency with procedural precision. We understand how to frame claims, present evidence, and preserve your rights in parallel district court and PTAB actions.
Our deep experience defending clients in high-stakes patent litigation gives us a critical edge when representing plaintiffs. We know the tactics opposing counsel will use to challenge your patent’s validity, and we design enforcement strategies that anticipate and neutralize those attacks.
When you contact Klarquist to enforce your patent rights, you’re not just hiring legal counsel-you’re engaging a litigation team that understands how to protect innovation and deliver results. Whether you are the general counsel at a Fortune 500 company or the CEO of a small tech firm, here’s what you can expect from us:
Rapid Case Assessment
We’ll quickly evaluate the strength of your patent, the nature of the alleged infringement, and the business context. Our team will help you understand your enforcement options and the potential risks and rewards of litigation.
Strategic Enforcement Planning
We don’t believe in one-size-fits-all litigation. We’ll craft a tailored strategy whether that means pursuing early resolution, licensing opportunities, seeking injunctive relief, or preparing for trial. Our goal is to align legal action with your business objectives.
Technical and Legal Depth
Our attorneys combine deep patent law expertise with advanced technical backgrounds. We know how to explain complex technologies to judges and juries and how to anticipate the defenses your opponent may raise.
Clear, Proactive Communication
You’ll always know where your case stands. We provide regular updates, strategic guidance, and budget transparency-so you can keep your executive team informed and in control.
