Patent trolls are back: Spotting and beating weak claims

On Behalf of | Jul 29, 2025 | Intellectual Property

Just when many companies thought patent trolls had faded away, they returned—armed with vague claims and aggressive demands. These non-practicing entities (NPEs) do not build products or deliver services. Instead, they buy old patents and use them as weapons to sue businesses that are too busy—or too underprepared—to fight back. If your company grows, develops new products, or acquires technology, you may already be on their radar.

Here is how to recognize a weak patent claim and take action.

What does a patent troll look like?

If you receive a vague threat over a patent you have never heard of, you might be facing a patent troll. These groups create confusion and pressure businesses into fast settlements.

You will often see red flags, such as a demand letter that lacks a specific explanation, a patent that does not relate to your products or services or a sender that operates without any real business. Trolls flood your team with legal jargon and tight deadlines to catch you off guard. When you recognize the signs early, you stay in control.

Why midsize companies attract trolls

Trolls often avoid large corporations with full-time legal departments and instead focus on midsize companies that lack dedicated patent lawyers. At the same time, these companies often grow quickly and generate valuable IP.

If you recently launched a new product, entered a competitive tech space or acquired another company with patents, trolls might view your business as an easy target. They look for companies with enough revenue to justify a lawsuit but not enough resources to mount a strong defense. You can stay ahead by developing a strategic legal approach.

How to respond strategically

A troll’s power often lies in your reaction. Do not let fear dictate your next step. Act calmly and with guidance.

Here is what to do:

  • Call your IP attorney: If you do not have a lawyer with patent litigation experience, consider getting outside counsel.
  • Do a quick internal review: Check if your product or service overlaps with the patent.
  • Push back: Trolls often fold when they see that your legal team will not back down.

These steps demonstrate your knowledge and readiness to take action. Many weak claims fall apart under even modest pressure.

Choose the right IP counsel

If you run a Fortune 500 company with a legal team or manage a growing business without in-house patent support, the right intellectual property counsel can make all the difference. For large companies, a skilled IP attorney can work alongside your patent team and file applications directly with the United States Patent and Trademark Office (USPTO). 

For small and midsize businesses, the attorney may act as your in-house IP department, handling your patents, trademarks and copyrights. They can also guide you through issues such as infringement, demand letters, licensing and invalidity opinions. With strong legal support, you can protect your ideas, limit your risks and keep your business moving forward.
