Let’s break down everything you need to know about hiring a lawyer for a patent infringement case—from what they do to how they help you win.

What Is Patent Infringement?

Patent infringement happens when someone uses, makes, sells, or imports your patented invention without permission. This can include a product, process, design, or technology that’s covered under a valid patent.

When to Hire a Patent Infringement Lawyer

You should hire a lawyer immediately if:

• Someone is selling or manufacturing your patented product.
• You’ve received a cease and desist letter claiming you’re infringing.
• You’re planning to enforce your patent rights through litigation.
• You’re negotiating a license or settlement for your invention.

What a Patent Infringement Lawyer Does

A qualified attorney will:

• Analyze patent validity and infringement scope.
• File lawsuits in federal court or the U.S. International Trade Commission (ITC).
• Defend against infringement claims if you’re accused.
• Negotiate settlements or licensing deals.
• Work with technical experts to prove infringement or invalidity.

Types of Patent Infringement Cases

1. Direct Infringement: Copying or selling the patented invention.
2. Indirect Infringement: Encouraging or contributing to infringement.
3. Willful Infringement: Knowingly violating a patent—can lead to triple damages.

To win your case, your lawyer must show that:

• Your patent is valid and enforceable.

Damages You Can Recover
