Introduction
Patent enforcement in the Nordic market doesn’t always make the front page of IP publications. The cases that dominate discussion are in EDTX, Düsseldorf, and increasingly the UPC. Denmark, Sweden, and Norway operate at a lower volume — but for companies launching products in Scandinavia, the enforcement environment matters, and it has specific characteristics that distinguish it from both the US and the major continental European venues.
In April 2025, the Danish Maritime and Commercial High Court issued a ruling in case BS-19037/2025 that clarifies the threshold for ex parte injunctions in patent cases — proceedings where an injunction can be granted without the defendant being heard first. The ruling establishes a very high bar, even in cases involving repeated infringement claims and an existing enforceable injunction against the same defendant.
For product companies planning Nordic market launches, the ruling is relevant in two directions: it confirms that Denmark will not easily grant ex parte patent orders that disrupt product launches without notice, and it underscores that the court’s procedural fairness standards are robust. That’s good news for well-prepared market entrants. It doesn’t mean Danish patent enforcement isn’t real. It means it operates differently from Germany. Understanding that difference is what effective FTO analysis for the Nordic market requires.
What an Ex Parte Injunction Is — and Why It Matters for Product Launches
An ex parte injunction is granted without notice to the defendant. The court hears only the patent holder’s side before issuing the order — the defendant is not given the opportunity to respond. In patent cases, this means a product can be ordered off the market before the alleged infringer has had any opportunity to contest the claim.
This is the most commercially disruptive enforcement tool in a patent holder’s arsenal. An inter partes preliminary injunction — where both parties are heard — takes several months. An ex parte order can be obtained within days or weeks of filing. For a product launched into a new market, an ex parte injunction can create immediate market disruption: product pulled from shelves, distribution channels frozen, customer relationships disrupted — all before the alleged infringer has been heard by the court.
For FTO strategy, ex parte injunction risk is a specific component of the launch risk assessment that sits alongside the underlying question of whether infringement exists. Even a product with a credible freedom to operate position faces ex parte risk if the jurisdiction grants such orders readily and the patent holder is willing to move quickly. Germany is notorious for this. Denmark, as the April 2025 ruling confirms, is not.
The April 2025 Danish Ruling: BS-19037/2025
Here’s what the case involved and what the court decided.
The court and its role: The Danish Maritime and Commercial High Court (Sø- og Handelsretten) is the first-instance patent court in Denmark. It handles both infringement actions and preliminary injunction applications in patent disputes. The court has specialised IP expertise and is the entry point for all patent enforcement proceedings in Denmark.
The case: In BS-19037/2025, a patent holder applied for an ex parte preliminary injunction. Significantly, there was already an enforceable injunction against the same defendant from prior proceedings. The patent holder argued that new infringement was occurring — that the defendant had resumed or continued infringing conduct in violation of the existing order — and sought an ex parte order to prevent the ongoing conduct without giving the defendant prior notice.
The decision: The court declined to grant the ex parte order. Even with an existing enforceable injunction and the allegation of renewed infringement, the court held that the threshold for excluding the defendant from the proceedings — the prerequisite for any ex parte order — had not been met. The defendant’s right to be heard was treated as a fundamental procedural protection, overridden only in circumstances so exceptional that notice itself would defeat the purpose of the order.
The principle: The ruling reflects a consistent Danish judicial philosophy: procedural fairness is a cornerstone of the legal system, and commercial disruption without adversarial process requires an exceptionally high justification. Having a prior injunction against the same defendant, and alleging violation of that injunction, is not sufficient justification — even combined — to bypass the defendant’s right to respond before an ex parte order issues.
“The April 2025 ruling doesn’t mean Danish courts won’t enforce patents. It means they won’t do it without giving the other side a chance to be heard — except in circumstances that are genuinely extraordinary. That’s a meaningful protection for companies entering the Danish market with a credible freedom to operate position.”
How Danish Patent Enforcement Actually Works
Understanding the ex parte ruling requires understanding the standard Danish enforcement framework that it sits within.
- First-instance proceedings at the Maritime and Commercial High Court. All patent infringement actions in Denmark are filed before the Maritime and Commercial High Court. The court has specialised IP panels with technical expertise. Proceedings are conducted in Danish, though international parties regularly participate through Danish counsel.
- Preliminary injunction process — inter partes. For most preliminary injunction applications in patent cases, the court hears both parties: written submissions followed by an oral hearing. A decision typically issues within 2–4 months of filing. The applicant must demonstrate (1) a valid patent, (2) a reasonable likelihood of infringement, and (3) that the balance of hardships favours the injunction. The third element — balancing of hardships — gives the court room to consider the commercial impact on both sides.
- Main proceedings and damages. Following a preliminary injunction, main proceedings must be initiated to confirm the injunction and pursue damages for infringement. Danish damages awards have historically been modest by international standards, though they are calculated based on lost profits or a reasonable royalty, whichever is greater.
- Validity challenges as counterclaims. Validity can be challenged as a counterclaim in infringement proceedings or through separate nullity proceedings before the Danish Patent and Trademark Office (DKPTO). Unlike Germany’s bifurcation model, Danish courts will hear both infringement and validity in the same proceeding if the defendant raises a nullity counterclaim — giving a more integrated process.
What the Ruling Means for FTO Strategy in the Nordic Market
The April 2025 ruling has specific and practical implications for FTO strategy. Here’s how to read it.
The cautious standard is good news for well-prepared entrants. A company that has conducted a thorough freedom to operate analysis for the Danish market, has a credible non-infringement or invalidity position on the relevant patents, and can document its FTO basis in writing is in a strong position relative to an ex parte injunction risk. Denmark’s high threshold for ex parte orders means that a patent holder who wants to stop a well-prepared market entrant before launch needs to go through the inter partes preliminary injunction process — which gives the entrant the opportunity to be heard and to present its FTO position. That’s a material procedural protection.
But inter partes injunctions remain available — and real. The April 2025 ruling addresses the ex parte threshold specifically. It does not change the availability or standards for inter partes preliminary injunctions in patent cases. A patent holder with a valid patent and a credible infringement argument can still obtain a preliminary injunction in Denmark — the process is simply adversarial rather than ex parte. For companies launching products in Denmark where a competitor holds potentially blocking patents, the inter partes preliminary injunction risk is the one that needs to be assessed in the FTO analysis.
Pharmaceutical and medtech: Denmark’s active enforcement track record. Denmark has a well-established enforcement track record in pharmaceutical and medical technology patent disputes. The Danish patent courts have experience with SPC-related disputes, biosimilar market entry cases, and medical device infringement claims. For pharma and medtech companies entering the Danish market, the cautious ex parte standard provides protection at launch — but the inter partes preliminary injunction environment is active and should be assessed thoroughly in any FTO analysis.
The Nordic FTO Picture: Denmark, Sweden, Norway
A product launched into the Nordic market doesn’t sit in a single jurisdiction — and the patent enforcement environment differs meaningfully across the three primary Nordic markets. Here’s what each one looks like for FTO purposes.
Denmark — Cautious ex parte standard (confirmed April 2025), but active inter partes preliminary injunction enforcement. Particularly active in pharmaceuticals, medical devices, and clean energy technology. The Maritime and Commercial High Court is specialised and efficient. FTO analysis needs to cover the Danish patent register, EPO-granted patents validated in Denmark, and SPC extensions for pharma products.
Sweden — Stockholm District Court handles patent disputes as first instance. Sweden is home to Ericsson and a significant concentration of telecoms and connectivity technology companies. SEP assertion activity is present in Stockholm given Ericsson’s home jurisdiction. Preliminary injunctions are available through the Patent and Market Court (PMD). FTO analysis for Swedish market entry needs to cover the Swedish patent register and the specific SEP landscape for connectivity-implementing products.
Norway — Norway is not an EU member but is a Lugano Convention signatory — relevant to UPC long-arm jurisdiction questions. Oslo District Court handles patent disputes. Norway has an active pharmaceutical patent enforcement track record, particularly in generic market entry cases. FTO analysis for Norwegian market entry needs to cover the Norwegian patent register and EPO-granted patents validated in Norway.
For companies planning pan-Nordic launches, the most common pitfalls in FTO analyses include treating the region as a single jurisdiction, scoping the FTO to one country while ignoring the others, and failing to account for the different preliminary injunction standards in each market. A Nordic FTO needs to be scoped as three separate jurisdictional analyses, not one.
How Our FTO Service Covers the Danish and Nordic Market
Our freedom to operate search service covers the Danish patent register, EPO-granted European patents validated in Denmark, and Scandinavian-specific patent databases for Swedish and Norwegian market analysis. Every Nordic FTO engagement covers each jurisdiction separately — Danish, Swedish, and Norwegian patent registers, EPO validations in each country, and SPC extensions for pharma and medtech products.
For the Danish market specifically, we structure FTO engagements to account for the April 2025 ex parte standard — assessing which competitor patents carry ex parte risk (low under the current standard) versus inter partes preliminary injunction risk (which remains real and active). The output isn’t just a patent clearance report. It’s a jurisdiction-specific injunction risk assessment that tells your team what enforcement mechanism is most likely for each potentially blocking patent, so you can plan your launch strategy accordingly.

Conclusion: The Takeaway
Denmark’s cautious approach to ex parte patent injunctions — confirmed in the April 2025 ruling — is meaningful for product companies entering the Nordic market. The procedural protection it provides at the point of launch is real: a patent holder wanting to stop a well-prepared market entrant before they’ve had a chance to be heard needs to go through adversarial inter partes proceedings, not a unilateral ex parte order.
That protection is conditional on preparation. A company that has conducted a thorough Denmark-specific FTO analysis, has a documented non-infringement or invalidity position on the potentially blocking patents, and can articulate that position to the court when given the opportunity to be heard is in a fundamentally better position than one that arrives at the market launch without that groundwork. The procedural fairness the Danish courts provide is only valuable if you’re prepared to use it.
Denmark enforces patents. It does so with procedural care. Understanding the difference between those two things is what effective Nordic FTO strategy looks like.
