Can a merger put your company’s patent rights at risk?

On Behalf of Fogarty IP | Nov 9, 2026 | Intellectual Property

Your company is preparing for a merger. Its patents represent years of research and investment. But will the deal give you all the rights you expect? While some patents may transfer by law, existing licenses and missing records can lead to disputes over ownership or limits on how your company uses patented technology.

How can a merger affect patent ownership?

The outcome depends on how the companies combine. In a statutory merger, two or more companies legally combine into one. State law may transfer these rights to the company that remains without a separate written assignment. However, existing license agreements may still limit those rights.

Other transactions follow different rules:

  • Stock purchase: When a buyer purchases a company’s shares, that company generally keeps ownership of its patents.
  • Asset purchase: When a buyer acquires patents, federal law requires a written assignment, or a document that transfers ownership.

These differences can help you understand whether ownership will change and what documents the deal may require.

What patent issues should you review before a merger?

Before a merger closes, several issues can affect which rights your company will own, use or enforce.

Three areas deserve attention:

  • Ownership records: Missing transfer documents can lead to disputes over who holds the rights.
  • Licensing agreements: A license allows a company to use another party’s patented invention. Some licenses require approval before rights can transfer or allow the owner to end the agreement after certain mergers.
  • USPTO records: If an ownership transfer is not recorded with the U.S. Patent and Trademark Office (USPTO), a later buyer who pays for the patent without knowing about the earlier transfer may have stronger legal rights.

Together, these concerns can affect the value of your company’s intellectual property and its plans after the merger.

Know what your company will own after the merger

A merger should not leave you uncertain about who owns your patents or which licenses remain in effect. An intellectual property attorney can help confirm which rights will transfer, flag contracts that need consent and identify gaps in ownership records. With these details clarified before closing, you can plan how your company will use and manage its intellectual property after the deal.
