Stay pending validity: what the other side does
When one side asks a court to pause an infringement case until a parallel validity challenge is resolved, the other side rarely welcomes the pause. It typically opposes the stay, argues urgency, or asks for a partial stay limited to the claims actually under attack. Some sides use the delay to open settlement talks instead of fighting the stay itself.
What a stay pending validity actually stops
A stay does not decide validity. It freezes the infringement track while a separate forum works through the challenge — an opposition, an appeal, or a nullity action running in parallel. Deadlines for evidence and hearings pause too, though the court usually keeps a review date on the file so the case does not fall off its list.
The other side treats the pause as tactical ground, not as a resolution. It watches the parallel proceeding closely, because the outcome there decides whether the infringement claim survives at all.
What changes for timing and risk
Once a stay is granted, the clock on infringement damages effectively stops moving against the party that sought the pause, but the underlying risk does not disappear — it shifts. If the validity challenge fails, the infringement case resumes from where it stood, often with a shorter window to prepare for trial.
For the party resisting the stay, the practical risk looks different: continuing infringement, lost market share, or a competitor gaining ground while the parallel case runs its course. That is usually why it pushes back rather than agreeing.
What to do next
- Confirm in the case file whether a stay request has been filed, and by whom.
- Instruct counsel to file observations opposing or supporting the stay within the deadline the court has set.
- Gather the underlying record: the patent file history, correspondence on the parallel challenge, and any licence or settlement offers already exchanged.
- Ask for a partial stay if only some claims are under challenge, so the rest of the case can proceed on schedule.
- Calendar the review date the court sets, and prepare to act the moment the parallel proceeding closes.
The discipline behind that record is the same discipline used to keep other digital records traceable — see Smart contract tokenised rights explained in detail — every filing, deadline and exchange needs a dated place in the file, not a loose folder of emails.
Who decides, and how long it usually takes
Deciding who acts and when is rarely automatic — the same question of authority resurfaces in other contexts, such as Who decides and when in this situation explained. In a stay dispute, the court seized of the infringement claim decides whether to pause it; the parallel forum handling validity has no say over the stay itself.
| Stage | Who acts | Typical timing |
|---|---|---|
| Stay request filed | Party seeking the pause | Any point before judgment on infringement |
| Observations from the other side | Opposing party | Within a court-set deadline, commonly a few weeks |
| Ruling on the stay itself | The seized court | Usually one to three months after filing |
| Parallel validity proceeding runs | Patent office or separate court | Independent timetable, often many months |
| Infringement case resumes or closes | The seized court | Promptly once the parallel decision is final |
These are typical ranges from practice, not fixed deadlines. Docket load, complexity of the patent, and how many claims are contested all move the numbers in either direction.
Two common scenarios
If you are the party requesting the stay, you carry the burden of showing that the validity challenge is serious enough to justify the pause, and that continuing would cause disproportionate cost to you.
If you are the party resisting the stay, you carry the burden of showing urgency — ongoing harm, a live market, or evidence that risks disappearing while the case waits.
If both sides value certainty over a drawn-out fight, the stay dispute sometimes turns into a settlement discussion instead of a ruling on validity at all.
What this page does not cover
This page describes the procedural mechanics of a stay. It does not value the underlying patent, price the litigation, or tell you whether requesting a stay serves your commercial position — those questions depend on the portfolio, the opponent, and the market at stake.
Before committing resources to either side of a stay dispute, many companies first map the counterparty and the cost of misjudging it: Counterparty report before appointing a developer in detail.

Frequently asked questions
How long does stay pending validity take in practice?
The ruling on the stay itself usually arrives within one to three months of the request. The pause then lasts as long as the parallel validity proceeding takes, which can run from several months to a few years depending on the forum and any appeal.
Which documents are needed to start?
The stay request or the observations opposing it, the patent file history, notice of the parallel challenge, and any correspondence already exchanged on settlement or licensing. Proof of urgency or ongoing harm strengthens either side's position.
What happens if the other side does not respond?
Courts commonly treat silence within the deadline as no objection and grant the stay unopposed, or they set a default deadline and rule on the record available. Silence rarely improves the non-responding party's position later in the case.
