What this is: The differences between ownership and assignment records at the US Patent and Trademark Office can be confusing. Especially when the search results do not always appear to correspond.
What this means: There are many reasons why USPTO assignment and ownership records may not match up and understanding how the USPTO updates its database is one of the first ways to help ease confusion. Read along to learn more.
“Ownership” confers an exclusive “right to use” to the mark or the patent. Patent protection is fixed at 20 years; trademark protection is renewable every 10 years. Ownership refers to the current owner of a registered trademark, a granted patent, a pending trademark or a pending patent application. Ownership of a patent excludes others from legally making, using, offering for sale, selling or importing the same invention into the United States . Ownership of a trademark registered on the Principal Register ordinarily confers an exclusive right to use the mark in connection with the goods or services listed on the registration and permits the U.S. Customs and Border Protection service to block imports bearing infringing marks .
Intellectual property (IP) is considered personal property – and, as such, rights to IP can be assigned .
Conveyance Types that Result in a Change to Ownership Records
Below are the assignment conveyances that will result in the automatic updating to patent and trademark ownership at the USPTO.
- Assignment (See below);
- Nunc Pro Tunc Assignment of entire interest and goodwill;
- Name Change
Accordingly, if filers want the ownership information in the USPTO records to be updated, they must check one of the above as the nature of conveyance on the electronic cover sheet for electronic filings. Selecting “other” conveyance on the electronic cover sheet will update patent ownership upon recordation but will not update trademark ownership.
Ownership records on the Trademark Database will not be automatically updated in the following situations:
- Conveyance type does not update ownership;
- Execution date of a previously filed document is the same or later than that of a subsequently filed document and when one files multiple assignments with the same execution date;
- Application is in a Blackout Period (phase between when the mark is approved for publication and when the registration issues);
- Maximum number of ownership changes is reached
In each of the above cases, a written request to update ownership information must be filed and USPTO personnel will then review the assignment records and update the database manually. The written request should include information regarding the proper order of the multiple transfers so that the correct chain of title may be determined and the ownership record updated accordingly in the trademark database .
UCC and IP due diligence services can be difficult to get right. Get started with our resource page on UCC, IP & Related Due Diligence Services.
Assignment is defined as a transfer by one party to another party of all or part of its interest and rights to IP . According to 15 U.S.C. §1060(a) and 35 U.S.C. §261, a registered mark, a mark pending registration, a patent and patent application (or any interest therein) are assignable. Assignments show the chain of title, whereas ownership lists the last recorded owner. Previous owners and assignees only appear on the assignment database.
There are two conveyance types for filing trademark assignments: “assignment of the entire interest and the goodwill” and “assignment of an undivided part of assignor’s interest”. The entire interest and the goodwill mean 100% of the trademark (inherent rights, title and ownership interest). In order to assign partial (<100%) trademark interest and goodwill, either check the “assignment of an undivided part of assignor’s interest” or check “other” and indicate “assignor assigns x percent”. Selecting “other” will not update trademark ownership. This disclaimer appears on the electronic filing system .
Patents offer a general “assignment” conveyance. When “assignment” is selected, 100% of the patent will be assigned. Partial assignments occur in cases where there are multiple inventors. For example, one inventor who owns 40% may assign their whole, undivided percentage to another entity. He or she must specify the percentage assigned in the “other” box, in the same way as for trademarks; “assignor assigns 40 percent”. The 40% is the bundle of rights associated with their ownership interest . Selecting “other” updates the patent ownership upon recordation.
Changes in Owner’s Name
Name change amendments occur when the ownership is unchanged, but there is merely a change in the owner’s name. The USPTO recommends trademark or patent owners to record the name change with the Assignment Recordation Branch .
Security Interest Conveyances
The security interest conveyance occurs when one company takes a security interest in the IP of another company. The interest is released upon loan satisfaction. While security interests and security agreements do not transfer title, they are still recorded for the sake of third parties who wish to know about matters concerning the property .
Example of Assignments Not Matching Up with Ownership Records
It is often confusing when a party is listed as the last assignee in a USPTO assignment chain of title, yet they are not listed as the current intellectual property owner. It is helpful to remember that a party does not need to be the owner in order to be linked to the property as an assignor or assignee in a USPTO recorded assignment. As a hypothetical example, let’s say Party A is the owner of a patent and assigned a security interest to Party B (as assignee). Party B (as assignor) released the interest back to Party A (as assignee) and Party A later mortgaged their rights to Party C, a new assignee. While neither assignment affected ownership, an assignment search on either Party B or Party C would reveal this patent as a valid result. An ownership search for either Party B or Party C would not find this patent.
Conversely, not all changes or updates to the ownership record are reflected in the assignment chain of title. Patents and trademarks may lack corresponding assignments because not all IP assignments are recorded with the USPTO. It is at the owner’s discretion to file an assignment.
As you can see, there are many reasons why USPTO assignment and ownership records may not match up. Understanding which types of filings affect ownership and how the USPTO updates its databases will make it easier for you to resolve the differences between these records. More questions?

Are names misspelled in the USPTO databases?
Yes. When data is manually keyed into a system over an extended period of time, keying errors are inevitable. Searchers should be aware of this and consider conducting searches on some of the more common errors.
Common misspellings include reversal of the letters (‘retrieve’ vs. ‘retreive’) and dropped double letters (‘dropped’ to ‘droped’). Use of British spellings, such as ‘colour’ instead of ‘color’ can also result in missed hits. Combined with punctuation and spacing variations, misspellings can wreak havoc on even the most diligent searcher. Read more here.
What should I search for on the USPTO website?
Consider devising a search strategy in advance that covers the following sections:
- Pending and registered trademarks
- Trademark assignments
- Published pending patents
- Patent grants
- Patent assignments
What type of UCC assignment filings can a secured party make?
There are several types of UCC assignment filings a secured party may make with the appropriate central filing office and/or local filing office:
- The secured party (assignor) may assign all of its rights to another party (assignee). (This is considered a full assignment.)
- The secured party may assign the rights to some portion or percentage of all the collateral covered by the initial UCC financing statement to another party. (A partial assignment.)
- The secured party may assign the rights of the 100% interest in a portion of the collateral to another party. (Also a partial assignment.)
