A major update is on the horizon from the United States Patent and Trademark Office (USPTO) that every patent and trademark holder — as well as investors — should be aware of. Beginning October 2025, the USPTO will replace its legacy assignment record search systems with a modernized USPTO Assignment Records Search. This change is set to streamline how ownership transfers are tracked and verified, making it easier to confirm who owns critical intellectual property. The update not only impacts on inventors and businesses but could also influence the investor decisions by improving transparency and reliability in IP ownership records.

What Are USPTO Assignment Records Search and What Changes Are Coming in 2025?
The first thing to understand is: what is an assignment record? An assignment record is the official document that shows the transfer of ownership for a patent or trademark. In simple terms, it is the record of when a patent or trademark changes hands. For example, when an inventor creates a patent, they may later assign (transfer) it to a company, a university, or even sell it to another individual. This process is often referred to as a patent transfer or patent sale. The same applies to trademarks. A trademark holder can sell, transfer, or assign their trademark rights to another business or individual. Every such transaction is officially recorded at the USPTO as part of the assignment record.
For years, inventors, businesses, and lawyers have relied on two separate tools — Patent Assignment Search and Assignments on the Web — to track ownership transfers of patents and trademarks. While useful, these platforms often felt outdated, forcing users to jump back and forth between systems. Recognizing this challenge, the USPTO decided it was time for a change.
On October 20, 2025, USPTO will retire its old systems and introduce a single, modern platform called Assignment Search. This tool is designed with simplicity in mind: users can start with a quick, basic search and, if needed, refine their results using advanced filters like dates, transaction types, or party names.
How the New USPTO Assignment Records Search Will Work
The upcoming USPTO Assignment Search system, launching in October 2025, is designed to replace outdated tools with a faster, simpler, and more reliable way to track patent and trademark ownership. Instead of juggling multiple systems, users will be able to search, filter, and verify assignment records all in one place.
The new USPTO Assignment Search will work:
- Access everything in one place: the USPTO Assignment Center.
- Use basic search (by patent/trademark number, name, or assignment ID).
- Refine results with advanced filters (date ranges, parties, transaction types).
- View ownership details in a modern, user-friendly interface.
- Benefit from better reliability, accuracy, and security compared to old systems
