Competition Law and Patent Pools Under Danish Competition Law

1. Introduction

A patent pool is an arrangement under which two or more patent holders place a group of patents into a common licensing structure and make those patents available to licensees, often through a single licensing mechanism. Patent pools can substantially reduce transaction costs, simplify licensing of complex technologies, and facilitate interoperability and standardisation.

At the same time, a patent pool can bring competing patent holders into close contact. It may therefore become a mechanism for price coordination, market allocation, exclusion of competing technologies, exchange of commercially sensitive information, or suppression of independent innovation.

Under Danish competition law, patent pools are principally assessed through the Danish Competition Act, interpreted consistently with EU competition law where the conduct affects trade between EU Member States. The central provisions are therefore the Danish rules corresponding to Article 101 TFEU, together with Article 102 TFEU where a patent pool or its administrator possesses a dominant position.

The modern EU technology-transfer framework is particularly important because the European Commission's new Technology Transfer Block Exemption Regulation entered into force on 1 May 2026, replacing the previous 2014 regime. (Competition Policy)

2. Legal Framework in Denmark

A. Danish Competition Act

The Danish Competition Act prohibits agreements, decisions and concerted practices between undertakings which have as their object or effect the restriction of competition.

For a patent pool, the relevant questions include:

Are the participating patent owners competitors?

Does the pool concern competing or complementary technologies?

Does the pool restrict independent licensing?

Does it determine royalty levels?

Does it allocate customers or territories?

Does it prevent members from independently developing competing technologies?

Does it exclude non-members?

Does it involve exchange of commercially sensitive information?

Where EU trade is affected, Article 101 TFEU applies alongside the Danish regime.

3. Why Patent Pools Raise Competition Issues

Patent pools have a distinctive dual character.

Potentially pro-competitive effects

A properly designed pool can:

reduce transaction costs;

eliminate the need for multiple bilateral licences;

reduce royalty stacking;

facilitate technological standards;

accelerate dissemination of technology;

reduce litigation;

promote interoperability; and

enable new products to enter the market more easily.

The European Commission expressly recognises that technology pools can have substantial pro-competitive potential, particularly where they create a one-stop licensing mechanism for complementary technologies. (Competition Policy)

Potentially anti-competitive effects

Conversely, a pool may:

facilitate collusion between competitors;

create collective market power;

impose excessive royalties;

exclude substitute technologies;

discriminate against outsiders;

prevent independent licensing;

restrict research and development;

exchange sensitive commercial information; or

become a vehicle for coordinated exclusion.

The European Commission's technology-transfer framework specifically recognises that technology arrangements can facilitate collusion, restrict market entry or expansion and reduce incentives for innovation. (Competition Policy)

4. Patent Pools and Article 101(1) TFEU

The first analytical question is whether the pool falls within the prohibition of restrictive agreements.

A patent pool involving competing undertakings is particularly sensitive because the participants may otherwise compete in:

licensing;

technology development;

product markets;

royalty negotiations; and

research and development.

The competition authority will therefore examine the actual economic function of the pool rather than merely its contractual form.

A pool consisting exclusively of complementary patents necessary for implementing a technological standard presents a very different competition problem from a pool combining mutually substitutable technologies.

5. The Importance of Essentiality

One of the most important safeguards is that a pool should generally contain essential and complementary technologies.

Suppose:

Patent A is necessary to implement Standard X;

Patent B is also necessary;

neither patent can realistically replace the other.

Combining them may create efficiencies.

But if:

Patent A and Patent B are competing technological alternatives,

putting them into the same pool may eliminate competition between alternative technologies.

The European Commission's revised technology-pool guidance reinforces this principle and requires greater transparency concerning the patents included in the pool and the methodology used to determine their essentiality. (Competition Policy)

6. Open Participation

A competitively structured pool should generally have an open and transparent participation mechanism.

A pool controlled by a small group of incumbents could potentially become an exclusionary mechanism.

For example, if several dominant Danish technology companies create a pool and deliberately refuse access to an emerging competitor possessing an important complementary patent, the pool may have exclusionary effects.

The traditional EU approach has therefore treated openness to interested technology rights holders as an important condition for favourable treatment.

7. Non-Exclusive Licensing

Another important safeguard is that patents should generally be licensed into the pool on a non-exclusive basis.

This preserves the ability of patent owners to:

license independently;

develop new technologies;

participate in alternative licensing arrangements; and

compete outside the pool.

The European Commission's technology-pool guidance has historically treated non-exclusive licensing as one of the conditions supporting favourable treatment. (Competition Policy)

8. FRAND Licensing

Where patents are associated with standards, FRAND—fair, reasonable and non-discriminatory—licensing becomes particularly important.

A pool possessing essential standardised patents can have significant bargaining power because manufacturers may have no realistic technological alternative.

Accordingly, discriminatory or excessive licensing terms may raise competition concerns.

The 2026 revised EU guidance specifically clarifies the application of FRAND principles to licences granted by the pool itself and also addresses the problem of double dipping, where licensees effectively pay twice for the same technology rights. (Competition Policy)

9. Royalty Coordination

One of the most significant risks concerns royalty determination.

A patent pool can legitimately establish a common licensing mechanism. However, it must not become a disguised mechanism for competitors to coordinate prices in downstream product markets.

Particular concerns arise where pool members agree upon:

minimum downstream prices;

resale prices;

output restrictions;

customer allocation;

territorial allocation; or

coordinated commercial strategies unrelated to the legitimate administration of the pool.

Restrictions involving pricing, output, market sharing and similar conduct are traditionally treated as particularly serious under Article 101. (Competition Policy)

10. Exchange of Sensitive Information

Patent-pool participants may possess sensitive information concerning:

future licensing strategies;

royalty expectations;

customers;

production;

sales;

research plans;

future technologies.

The pool should not become a platform for competitors to exchange information that they could not legitimately exchange outside the pool.

The EU technology-pool framework therefore emphasises limiting exchanges of commercially sensitive information to information genuinely necessary for establishing and operating the pool. (Competition Policy)

11. Patent Pools and Article 102 TFEU

Article 102 may become relevant where the pool or its administrator possesses dominant market power.

Potential abuses include:

Excessive licensing terms

A dominant pool may impose royalties substantially disconnected from the economic value of the relevant technology.

Discriminatory licensing

The pool may grant favourable terms to selected members while imposing materially less favourable terms on rivals.

Refusal to license

A dominant pool may potentially engage in exclusionary conduct by denying access to indispensable technology, although the legal test for compulsory access to intellectual property is demanding.

Bundling

A pool may require licensees to take unnecessary patents together with essential patents.

Tying

A licensee may be required to acquire unrelated technologies as a condition of obtaining access to essential patents.

12. Danish Competition Authority's Role

The Danish Competition and Consumer Authority may investigate competition concerns arising within Denmark.

Its analysis will generally consider:

definition of the relevant technology and product markets;

market shares;

substitutability of technologies;

essentiality of pooled patents;

governance structure;

licensing conditions;

membership criteria;

royalty structure;

information exchanges;

exclusionary effects; and

efficiency benefits.

Where the matter has an EU dimension, Danish enforcement operates within the broader EU competition-law framework.

13. Case Laws

Direct Danish reported litigation specifically concerning modern patent pools is comparatively limited. Consequently, Danish analysis relies heavily upon EU competition jurisprudence concerning intellectual property, licensing, standardisation, collective licensing and Article 101/102, together with the technology-transfer framework.

The following cases are particularly useful.

Case 1: Commission Decision – MPEG-2 Patent Pool

MPEG-2

Commission Decision concerning MPEG-2, Case COMP/38.173

The MPEG-2 patent pool concerned patents necessary for implementation of the MPEG-2 technology standard.

The case is important because it illustrates the competition-law distinction between:

pooling complementary essential patents; and

pooling substitute technologies.

Principle

A pool involving patents that are technically complementary and necessary for implementing a standard can generate significant efficiencies.

The case demonstrates why essentiality analysis is central to patent-pool assessment.

Danish relevance

A Danish patent pool involving standard-essential technology would likely be assessed using substantially the same economic principles where EU competition law applies.

14. Case 2: Commission Decision – DVD Patent Licensing

DVD Patent Licensing

Commission Decision concerning DVD technology licensing

The Commission examined arrangements concerning patents necessary for DVD technology.

The broader importance of the case lies in the treatment of collective licensing of essential technologies.

Principle

A licensing structure can facilitate access to technologically necessary patents, but competition law remains concerned with:

licensing restrictions;

discrimination;

access;

royalty structures; and

the competitive relationship between technologies.

Danish relevance

A Danish pool involving consumer electronics, telecommunications or digital standards could present substantially similar issues.

15. Case 3: IMS Health v NDC Health

Case C-418/01, IMS Health GmbH & Co. OHG v NDC Health GmbH & Co. KG

This is one of the leading European cases concerning intellectual property and compulsory access.

The Court considered circumstances in which refusal by a dominant undertaking to license intellectual property could constitute an abuse of dominance.

Principle

An intellectual-property right does not automatically place conduct outside Article 102.

However, the conditions for requiring access to protected intellectual property are stringent.

The case established important criteria concerning:

indispensability;

elimination of competition;

prevention of a new product or service; and

absence of objective justification.

Importance for patent pools

A dominant patent pool could potentially face Article 102 concerns if access to its technology were indispensable and the refusal satisfied the demanding conditions established by the Court.

16. Case 4: Microsoft v Commission

Case T-201/04, Microsoft Corp. v Commission

The Microsoft case concerned refusal to provide interoperability information and abuse of dominance.

Although it was not a patent-pool case, it is highly relevant to technology-access analysis.

Principle

Intellectual-property protection does not provide an unlimited immunity from competition law.

Where proprietary technology becomes indispensable for effective competition, refusal of access may, under stringent circumstances, constitute abusive conduct.

Patent-pool relevance

A dominant technology pool controlling indispensable interoperability technologies must therefore consider whether access conditions unnecessarily exclude competitors.

17. Case 5: Huawei Technologies v ZTE

Case C-170/13, Huawei Technologies Co. Ltd v ZTE Corp.

This is one of the most important cases concerning standard-essential patents (SEPs).

The Court examined the circumstances in which enforcement of an SEP may constitute an abuse of dominance.

Principle

The Court established a framework governing negotiations between an SEP holder and a potential licensee, including:

notification of infringement;

expression of willingness to obtain a licence;

FRAND negotiations; and

conduct expected from both parties.

Patent-pool significance

Where a patent pool administers SEPs, Huawei v ZTE is highly relevant to:

licensing negotiations;

FRAND obligations;

injunction strategies;

good-faith negotiations; and

abuse-of-dominance risks.

18. Case 6: Rambus

Rambus Inc.

Commission Decision, Case COMP/38.636

Rambus concerned patents and standardisation, particularly allegations concerning conduct surrounding the standard-setting process.

The case illustrates the competition risks that may arise when intellectual-property rights interact with standard-setting institutions.

Principle

Competition concerns may arise not merely from licensing itself but from the strategic acquisition or use of intellectual-property rights in the standardisation process.

Patent-pool relevance

A patent pool should therefore examine whether its governance structure permits members to manipulate standard-setting processes or conceal relevant intellectual-property interests.

19. Case 7: AstraZeneca

Case C-457/10 P, AstraZeneca AB and AstraZeneca plc v Commission

The AstraZeneca case concerned abuse of dominance involving intellectual-property and regulatory mechanisms.

The Court confirmed that the exercise of rights associated with intellectual property can constitute abusive conduct where the undertaking uses regulatory or legal mechanisms in a manner that departs from competition on the merits.

Patent-pool significance

The case demonstrates that:

Intellectual-property rights are not an absolute exemption from competition law.

A dominant patent pool must therefore distinguish legitimate IP protection from conduct designed principally to exclude competitors.

20. Case 8: Servier

Case C-176/19 P and related appeals, Servier

The Servier litigation concerned pharmaceutical patent settlements and competition law.

It illustrates how patent rights can intersect with Article 101 where arrangements between patent holders and potential entrants affect market entry.

The European Commission has expressly stated that patent settlements do not enjoy a special immunity from Article 101 merely because they concern patent disputes. (European Commission)

Patent-pool relevance

The case is useful by analogy where a pool uses patent rights or settlement mechanisms to prevent competing technologies or products from entering the market.

21. Case 9: European Commission – Qualcomm

Qualcomm

Commission Decision in Qualcomm, AT.39711

Qualcomm illustrates the interaction between technological intellectual property and competition law in highly concentrated technology markets.

Although not itself a conventional patent-pool case, it demonstrates the importance of examining:

market power;

licensing structures;

exclusionary incentives;

technological dependence; and

competitive effects.

For a Danish patent pool operating in telecommunications or semiconductors, these issues may be particularly significant.

22. The 2026 Technology Transfer Regime

A particularly important development for Danish competition-law analysis is the new Technology Transfer Block Exemption Regulation, Commission Regulation (EU) 2026/877.

It entered into force on 1 May 2026 and will remain applicable until 30 April 2038. (Competition Policy)

The associated guidelines contain updated treatment of technology pools.

The revised guidance specifically strengthens the requirements concerning:

identification of pooled rights;

assessment of essentiality;

transparency;

FRAND licensing;

prevention of double dipping; and

licensing-pool governance. (Competition Policy)

This is particularly relevant for a Danish undertaking establishing or participating in a patent pool after 2026.

23. Safe-Harbour Characteristics for Patent Pools

A patent pool has a stronger competition-law position where it generally demonstrates the following characteristics:

24. Patent Pools Involving Competitors

The most difficult situation arises where all pool members are direct competitors.

For example:

Five Danish manufacturers compete in producing a particular electronic device. Each owns patents relating to different components of a common technological standard.

A pool may allow manufacturers to obtain all essential licences through one mechanism.

That can produce efficiencies.

However, the same five firms should not use the pool to exchange:

future prices;

production plans;

customer allocations;

sales forecasts;

future product strategies; or

unrelated licensing negotiations.

The distinction between legitimate pool administration and cartel coordination is therefore crucial.

25. Patent Pools and Standard-Essential Patents

Patent pools are particularly common in industries involving standards, including:

telecommunications;

video codecs;

Wi-Fi;

digital broadcasting;

consumer electronics;

automotive technology;

IoT;

connected devices; and

semiconductor technologies.

SEPs create special competition concerns because implementation of a standard may make access to particular patents practically unavoidable.

This creates the possibility of:

standardisation → essential patents → collective licensing → market power → FRAND obligations.

The Huawei v ZTE framework is consequently highly relevant.

26. Patent Pools and Innovation

Competition authorities must also consider innovation competition.

A pool may increase innovation by:

making complementary technology available;

reducing licensing costs;

facilitating interoperability;

reducing litigation;

enabling smaller manufacturers to access technology.

But it may reduce innovation where:

substitute technologies are pooled;

members coordinate R&D;

outsiders are excluded;

future technologies are unnecessarily captured;

competing research programmes are suppressed.

The EU technology-transfer framework expressly recognises that technology licensing arrangements can affect incentives for innovation. (Competition Policy)

27. Patent Pool Governance

Governance is therefore a central issue under Danish competition law.

A well-designed pool should establish:

independent administration;

objective admission criteria;

independent essentiality assessments;

transparent licensing rules;

restrictions on information sharing;

non-discriminatory licensing;

independent royalty administration;

procedures for adding new patents;

mechanisms for challenging essentiality determinations; and

compliance monitoring.

The more control participating competitors exercise collectively over commercial matters unrelated to the pool, the greater the competition risk.

28. Exclusion of Non-Members

Exclusion can become problematic where a pool controls technology that is essential for competing in the downstream market.

Consider:

Companies A, B and C create a pool containing virtually every essential patent needed to manufacture a particular product. Company D possesses a complementary patent but is denied access.

The competition analysis would examine:

whether D's technology is essential;

whether membership is objectively available;

whether the exclusion affects downstream competition;

whether the pool members compete with D;

whether exclusion has an objective justification; and

whether the pool has substantial market power.

29. Double Dipping

A significant modern issue is double dipping.

Suppose a licensee pays:

a royalty directly to Patent Owner A; and

a second royalty to the patent pool for the same patent rights.

The economic effect may be equivalent to charging twice for the same technology.

The revised 2026 EU technology-pool guidance specifically addresses this concern and requires pool structures to avoid such duplication. (Competition Policy)

This is particularly important for Danish pools operating alongside bilateral licensing arrangements.

30. Danish Competition-Law Test

A practical Danish analysis can therefore proceed in the following sequence:

Step 1 – Identify the undertakings

Determine who owns the patents and whether they compete.

Step 2 – Define relevant markets

Identify:

technology markets;

licensing markets;

downstream product markets.

Step 3 – Examine the patents

Determine whether they are:

essential;

complementary;

substitutable; or

unrelated.

Step 4 – Examine the pool

Analyse:

membership;

governance;

licensing;

royalty determination;

information exchange.

Step 5 – Article 101(1)

Determine whether the arrangement has an anti-competitive object or effect.

Step 6 – Block exemption / Article 101(3)

Assess whether the arrangement creates efficiencies that benefit consumers and whether restrictions are indispensable.

Step 7 – Article 102

If the pool or its administrator is dominant, examine possible exclusionary or exploitative abuse.

Step 8 – Remedies

Possible remedies include:

modifying membership rules;

removing non-essential patents;

changing licensing terms;

eliminating discriminatory provisions;

restricting information exchange;

revising royalty mechanisms; or

terminating anti-competitive provisions.

31. Overall Legal Position

Patent pools are not inherently unlawful under Danish competition law.

Their legality depends substantially upon their economic structure and operation.

A pool is more likely to generate competition-law concerns when it:

combines competing technologies;

excludes important competitors;

fixes downstream prices;

allocates customers;

restricts independent R&D;

exchanges sensitive information;

imposes discriminatory licensing terms;

uses collective market power to foreclose rivals; or

exploits essential patents to impose unjustified conditions.

Conversely, a pool based on essential and complementary patents, open participation, independent governance, non-exclusive licensing, transparent essentiality assessment and appropriate FRAND conditions can produce substantial efficiencies.

The European Commission's current framework expressly recognises this pro-competitive potential while strengthening safeguards concerning essentiality, transparency, FRAND licensing and double dipping. (Competition Policy)

Conclusion

Under Danish competition law, patent pools occupy the intersection of intellectual-property protection, Article 101/102 principles, technology licensing and standardisation. Danish authorities must balance the legitimate purpose of aggregating complementary patent rights against the danger that competing patent holders will use the pool as a mechanism for collective market power.

The most important legal principles emerging from MPEG-2, DVD technology licensing, IMS Health, Microsoft, Huawei v ZTE, Rambus, AstraZeneca and Servier are that intellectual-property rights do not create blanket competition-law immunity; complementary and essential technology can justify cooperative licensing; access and FRAND issues become particularly important for SEPs; and collective licensing must not become a vehicle for cartelisation or exclusion.

For Denmark, the 2026 EU Technology Transfer Block Exemption Regulation and revised Technology Transfer Guidelines are especially important because Danish patent-pool arrangements with an EU dimension will need to be assessed against this updated framework. (Competition Policy)
