When an assignment breaks the chain of title: what to do first
An assignment breaks the chain of title when a transfer — of a patent, trade mark, or copyright — is missing, misdated, wrongly signed, or unrecorded. The first step is not litigation. Freeze reliance on the licence, map the gap in writing, and instruct counsel to assess whether it is curable before the next payment or deadline.
What the framework says
The governing framework depends on which right sits in the broken link. An EU trade mark assignment falls under Regulation (EU) 2017/1001 (EUTMR), which treats the register entry as the reference point for third-party effect. Software forming part of the same file is protected at EU level under Directive 2009/24/EC, transposed into the national law of each member state. Where the file also includes a database, Directive 96/9/EC applies in the same way. If a unitary patent sits in the chain, Regulation (EU) No 1257/2012 governs the underlying protection, separately from any national filing that preceded it.
| Right in the chain | EU framework | Typical break |
|---|---|---|
| EU trade mark | Regulation (EU) 2017/1001 (EUTMR) | Assignment executed but never recorded at the register |
| Software copyright | Directive 2009/24/EC | No written assignment from an author, founder, or contractor |
| Database right | Directive 96/9/EC | The maker of the database is not identified anywhere in the chain |
| Unitary patent | Regulation (EU) No 1257/2012 | The prior national filing was not properly carried into the current file |
None of these instruments tells you how to fix a specific gap. They tell you which register or protection regime the fix has to satisfy once you have found it.
What actually changes
A broken link does not, by itself, void the underlying right. It strips the current holder's practical ability to enforce it, licence it further, or record any new transfer until the gap closes. Every downstream licence inherits the same defect, whether or not the licensee knows about it. Meanwhile, nothing pauses: a renewal, a recordal window, or a payment obligation under an existing agreement keeps running while the fix is being prepared. Treat the gap as live from the day it is found, not from the day it is corrected.
What to do first
- Freeze new grants and payments tied to the affected right, pending confirmation of title — decision sits with the rights holder or general counsel.
- Pull the full assignment history and mark the exact step that is missing, misdated, or wrongly signed — in-house counsel or instructed IP counsel.
- Identify who should have signed that step, and whether that party still exists in the same legal form — instructed counsel.
- Draft a confirmatory assignment or deed of ratification and route it for signature before the next deadline — instructed counsel.
- File the correction with the register that holds the original entry, once signed — IP counsel or a registered agent.
- Notify counterparties whose licences or security interests depend on the corrected step — rights holder.
Who decides
The decision to accept a corrected assignment sits with the register that holds the original entry: the EUIPO for an EU trade mark, the national office where a unitary patent's underlying filing sits, or the relevant national register where one exists for copyright or database rights. Registers decide on the documents filed, not on an account of what the parties intended at the time. Where the parties themselves dispute the correction, a national court decides, at the seat of the right or under whatever jurisdiction clause the parties agreed.
Three forks worth checking now
If the affected right is an EU trade mark and a rebrand is already under way, resolve the chain first. Filing a new mark over an unclear owner compounds the recordal failure rather than fixing it — see A rebrand collides with an earlier right trade mark for the adjacent conflict.
If the gap traces back to an acquisition, the missing signature usually belongs to someone inside the acquired team, not the acquiring company. That is a due-diligence failure, not a licensing dispute, and it is handled differently — see When an acquired team brings prior work: what to.
If the right has been tokenised and the smart contract still names an owner that no longer matches the paper chain, both records need correcting at the same time, not one after the other — see When the issuer loses control of the contract explained.
What this page does not resolve
This page sets out the first move and the decision-maker. It does not resolve a genuine ownership dispute on the merits, it does not replace the filing rules of any specific national office, and it does not tell you whether a particular defect is curable — that depends on the document itself and on facts we have not seen. Where more than one jurisdiction is involved, the correction usually has to be filed separately in each one; the mechanics differ by register even though the underlying EU framework is the same.

FAQ
What is the first step when an assignment breaks the chain of title?
Freeze reliance on the affected right and locate the exact missing or defective step in writing, before approaching the register or the other party.
Which deadline is already running?
Whatever deadline attached to the right before the gap was found — a renewal, a recordal window, or a payment date under an existing agreement — continues to run while the correction is prepared.
Who decides, and on what evidence?
The register holding the original entry decides on the documents filed. A dispute between the parties over what was intended is decided by a court, on written and signed evidence, not on an oral account.
