Licence disputes and royalty audits: step by step move through four phases: triggering the audit right, reviewing the licensee's books, quantifying any shortfall within the contractual notice window, and escalating unresolved claims through the dispute clause or before the Patent and Market Court. Missing the notice deadline usually extinguishes the claim.
Who this concerns
This sequence matters to licensors who suspect underreporting and to licensees who have just received an audit notice they did not expect. It comes up most often in three configurations: a patent or trade mark licence where royalties are calculated as a percentage of net sales and the definition of "net sales" has drifted from the licensee's actual invoicing practice; a technology or know-how licence where sublicensing to a third party has occurred without the licensor's knowledge; and a distribution arrangement dressed up as a licence, where the royalty base and the commission base have become blurred over several renewal cycles.
The people who need this sequence are IP counsel preparing to exercise an audit clause, finance controllers on the licensee side responding to one, and portfolio managers deciding whether a discrepancy is large enough to justify the cost of a formal audit. None of this replaces reading the Intellectual Property & UPC practice pages on the underlying licence terms, but it gives the order of operations once a dispute is live.
Cross-border structures change the calculus at every step. If the licensee is a foreign subsidiary reporting through a parent company, the audit clause's practical value depends on whether the parent has given a guarantee, whether the licence specifies a governing law and forum, and whether any Swedish judgment obtained at the end of the process can actually be enforced against assets sitting in another jurisdiction. A royalty audit that looks straightforward on paper can become a recognition and enforcement problem the moment the licensee's balance sheet sits outside Sweden.
What the law says
Under Swedish law as it currently stands, the right to audit a licensee's books is not a standalone statutory entitlement. It exists because the parties wrote it into the licence, and its scope, the auditor selection mechanism, the notice period, and the consequence of a confirmed shortfall are all matters of contract interpretation first. Where the licence is silent or ambiguous on the audit mechanism, a Swedish court supplementing the agreement will look at how the parties have behaved under the contract to date and at the overall allocation of risk in the licence, rather than importing a default statutory audit regime, because none exists in general terms for private commercial licences.
The competent forum for a Swedish-seated dispute of this kind is ordinarily the Patent and Market Court (Patent- och marknadsdomstolen), the specialist court that handles intellectual property and commercial disputes together, including royalty and licence disagreements that turn on IP rights. Where the underlying right is a European patent covered by the unitary system, and the dispute concerns validity or infringement rather than pure royalty accounting, proceedings may instead fall within the jurisdiction of the Unified Patent Court (UPC), the pan-European court created for patent litigation across participating states. A royalty dispute that is purely about accounting rarely reaches the UPC on its own; it becomes relevant mainly where the audit uncovers unauthorised use that also raises an infringement question.
Because the specific statutory cross-references for this dispute type are not confirmed against the current registry for this material, no article numbers are cited here. The mechanics below hold regardless of which specific provision ultimately applies to a given contract.
How it works in practice
Step 1: Confirm the audit trigger
Before anything else, check what actually gives rise to the right to audit. Most licences condition it on a fixed notice period, a maximum frequency (once per year, once per quarter), and sometimes a threshold of suspected discrepancy before the licensor can invoke it at all. Exercising the right outside these conditions can itself be treated as a breach by the licensee, so this step is not a formality.
Step 2: Serve the audit notice within the contractual window
The notice must go to the address and the recipient specified in the licence, not simply to whoever normally handles royalty statements. Many disputes are lost or delayed at this stage because the notice went to the wrong entity in a group structure, particularly where the licensee has since been restructured or acquired.
Step 3: Select and brief the auditor
Licences typically specify who may conduct the audit: an independent accountant, a named firm, or either party's own internal audit function subject to confidentiality undertakings. Briefing the auditor on the exact scope agreed in Step 4 before work begins avoids a report that is later challenged as exceeding its mandate.
Step 4: Define the scope of the audit
Scope disputes are common and usually concern three questions: which entities' books are open to inspection (the licensee only, or its subsidiaries and sublicensees too), which time period is covered, and whether the audit extends to underlying sales and manufacturing records or only to the summary royalty statements the licensee has already provided.
Step 5: Conduct the on-site or document review
Depending on the licence, this happens on the licensee's premises or through document production. The auditor compares actual sales, production, or usage figures against what has been reported and paid, working from the definition of the royalty base set out in the licence itself rather than from any general accounting standard.
Step 6: Quantify the shortfall
The auditor's output should distinguish between a genuine underpayment, a difference caused by a disputed interpretation of the royalty base (for example, whether returns or discounts are deducted before or after the royalty calculation), and simple clerical error. Only the first category typically supports a claim without further argument on contract interpretation.
Step 7: Serve the claim notice
Once quantified, the shortfall must be notified formally and within whatever period the licence sets for doing so. This is the single most consequential deadline in the entire sequence.
Step 8: Attempt resolution under the escalation clause
Most well-drafted licences require a period of negotiation, sometimes mediation, before litigation can begin. Skipping this step where the clause makes it mandatory can result in a claim being stayed or dismissed as premature.
Step 9: Escalate to arbitration or the Patent and Market Court
Where the licence provides for arbitration, that clause displaces court jurisdiction for the underlying claim. Where it does not, and the dispute is Sweden-seated, proceedings normally go before the Patent and Market Court.
What to check before serving any notice
- The exact definition of "net sales" or the royalty base as drafted, not as commonly understood in the industry.
- Whether the audit right survives termination of the licence, or lapses with it.
- The identity and authority of the person who must receive notices under the licence.
- Whether a materiality threshold exists below which a discrepancy does not trigger a right to claim.
- Whether the licence specifies a governing law and forum that differs from where the licensee's assets actually sit.
- Any prior waiver, by conduct or in writing, of strict compliance with the audit or notice mechanism.
How long does a licensor have to notify a royalty shortfall?
The period is set by the licence itself and varies significantly between contracts; some fix a specific number of days from discovery, others tie it to the audit report's delivery date. There is no general statutory default that overrides a clearly drafted notice clause, so the licence text controls.
Can a licensee refuse a royalty audit?
Only if the audit is being conducted outside the scope, frequency, or notice conditions the licence actually permits. A licensee cannot generally refuse an audit that complies with the contractual mechanism, though it can dispute the auditor's findings once produced.
What happens if the parties cannot agree on the auditor?
The licence usually names a selection mechanism, such as a professional body nominating an independent accountant if the parties cannot agree. Where the licence is silent, this becomes a preliminary point of dispute that can delay the substantive audit by months.
The numbers
No specific deadlines, thresholds, or limitation periods are stated here because the underlying registry entries for this material are not confirmed at the time of writing. What can be said with confidence is qualitative: the notice period for reporting a shortfall, the frequency limit on audits, and any materiality threshold are all matters the licence itself fixes, and they differ enough between contracts that a generic figure would mislead more than it would help. The limitation period that ultimately applies to a royalty claim depends on how the claim is characterised in the specific dispute and on the governing law clause, and should be confirmed against the actual licence rather than assumed from a rule of thumb.
Where it usually goes wrong
The sequence above assumes a licence that clearly addresses audit rights, notice, and dispute escalation. It breaks down in several recurring situations. Where the audit clause is silent on scope, the parties end up litigating the scope of the audit before they ever get to the substance of the shortfall, which can consume as much time as the underlying dispute. Where the royalty base definition has not kept pace with how the licensee's business has evolved, for instance after a change in distribution model or a shift to bundled pricing, a technically accurate audit can still produce a figure neither side accepts as fair, and the dispute becomes one of contract interpretation rather than accounting.
Insolvency changes the picture substantially. If the licensee has entered restructuring or the equivalent of Swedish company reorganisation, a confirmed royalty shortfall becomes an unsecured claim competing with other creditors, and the practical value of winning the audit dispute can be far lower than the quantified figure suggests. Where the licensee is a foreign entity and the group's assets sit outside Sweden, a Patent and Market Court judgment is only as useful as the recognition and enforcement route available in that other jurisdiction, and that route should be checked before the audit is even initiated, not after judgment.
Termination timing is another recurring trap. Some licences extinguish the audit right on termination unless a survival clause says otherwise, which means a licensor who waits too long after terminating a licence to check compliance may find there is no contractual audit mechanism left to invoke at all.
What to do next
This sequence takes a licensor or licensee from suspected underreporting to a quantified, notified claim. It does not replace a review of the specific licence text, which is where scope disputes, materiality thresholds, and survival clauses are actually decided, and it does not extend to enforcement against a foreign licensee's assets, which is a separate jurisdictional question.
Where the audit has produced a figure and the licence's dispute mechanism is about to be engaged, the next step is usually a preliminary assessment of the claim's strength against the actual contract wording rather than against the general pattern described here. Book a preliminary assessment before serving the claim notice, particularly where the licence's audit clause is ambiguous or where the licensee sits in another jurisdiction.
Where the underlying dispute concerns unauthorised use rather than pure underreporting, the questions overlap with product copying and design rights; see design protection and product copying for that adjacent scenario.
