From Achievement to Defense: What to Do When Your Patent Is Infringed

From Achievement to Defense: What to Do When Your Patent Is Infringed

Nov 20th 2025

When you receive a patent, it is the culmination of years of hard work, a symbol of your exclusive right to your innovation. But what happens when that right is challenged? Understanding how to enforce your patent is essential to protecting your invention—and the investment you've made in your idea.

The Power of Your Patent: Visible Ownership and Value

A granted patent from the USPTO is more than just a legal document—it is proof of ownership. It is your shield against unauthorized use and your foundation for building a business.

Why You Sought a Patent:

You sought a patent to protect something truly unique. After years of research, design, and rigorous review, your granted patent stands as official, public recognition of your achievement.

Once it's approved, take the time to formally recognize this monumental success. Celebrating and displaying your patent is the first step in reinforcing its value.

A commemorative patent plaque or award serves a powerful dual purpose:

  • A Symbol of Pride: It honors the inventor and the journey of innovation.
  • A Declaration of Ownership: A professional, visible display reminds visitors, competitors, and colleagues that your intellectual property is serious business.

Fun Fact: Nearly half of all patents granted in the United States belong to international inventors, all seeking the robust legal protections and recognition offered by U.S. patent law.

What to Do When You Suspect Patent Infringement

The visibility of your patent award underscores the seriousness of your IP. If you believe someone is copying or selling your patented invention, remain calm, but act swiftly and strategically.

Step-by-Step Enforcement Strategy

When facing potential infringement, a methodical approach is key to defending your rights:

  1. Gather Evidence and Consult an Expert
    Your defense begins with documentation. Collect all available evidence:
    • Product samples, marketing materials, and sales data of the infringing product.
    • Retrieve your official patent file from the USPTO.
    Next, consult a registered patent attorney. They will analyze the accused product against your patent's claims and advise you on the strength of your case.
  2. Issue a Cease-and-Desist Letter
    This formal document notifies the alleged infringer of your patent rights and demands they stop unauthorized use. Often, this initial step is enough to prompt a discussion and resolve the issue without litigation.
  3. Negotiate for a Settlement or License
    If the other party wishes to continue using your patented technology, you can negotiate a licensing agreement or settlement. These arrangements allow you to maintain ownership while generating ongoing revenue from your innovation.
  4. File a Patent Infringement Lawsuit
    If negotiations fail, filing a federal patent lawsuit may be necessary. This process seeks an injunction (to stop further use) and monetary damages for lost profits or royalties.

Defend Your Innovation and Display Your Achievement

Your patent is a testament to your hard work and a powerful business asset—but its value is only realized when it is protected and respected. By documenting your rights, consulting experts, and acting decisively, you ensure that your intellectual property remains secure.

Remember, every time you or a visitor sees your professionally displayed patent award plaque, it reinforces the respect and ownership that your innovation deserves. Recognize the achievement, secure the value.
