1. Introduction

Innovation ecosystem concentration refers to a situation in which a small number of firms acquire substantial control over the resources, technologies, infrastructure, data, standards, talent, distribution channels, intellectual property, financing, or complementary products necessary for innovation.

Competition law is concerned not merely with the number of firms conducting research and development (R&D), but with whether concentration allows one or a few firms to control the conditions under which innovation occurs.

An innovation ecosystem may include:

• technology platforms;
• cloud infrastructure;
• operating systems;
• app stores;
• semiconductor manufacturing;
• intellectual property and patents;
• research data;
• AI models and computing capacity;
• venture capital and acquisition markets;
• distribution networks;
• interoperability standards;
• technical interfaces and APIs;
• specialized suppliers;
• skilled labour and technical talent.

Concentration can sometimes produce efficiencies. Large firms may have greater resources for R&D, economies of scale, access to capital, and the ability to commercialize expensive technologies. Competition concerns arise when concentration enables firms to exclude rivals, acquire emerging competitors, restrict interoperability, foreclose complementary innovators, or suppress future sources of competition.

2. Meaning of Innovation Ecosystem Concentration

Traditional competition analysis often asks:

How much market power does a firm possess in a defined relevant market?

Innovation-ecosystem analysis additionally asks:

Does the firm control critical inputs or relationships that determine how innovation develops across interconnected markets?

For example, a technology company could possess market power because it controls:

data → computing infrastructure → AI models → APIs → application distribution → users.

Even if each layer constitutes a separate market, control across several layers may create cumulative competitive advantages.

Thus, ecosystem concentration can involve:

A. Horizontal concentration

Several firms competing at the same level of innovation become concentrated through mergers or acquisitions.

B. Vertical concentration

A firm controls multiple stages of the innovation chain.

Example:

semiconductor design → chip manufacturing → cloud computing → AI model development.

C. Platform concentration

A platform becomes an important intermediary between innovators and customers.

D. Data concentration

One firm accumulates datasets that competitors cannot easily reproduce.

E. Intellectual-property concentration

Essential technologies become controlled through patents, standards, licences, or proprietary interfaces.

F. Financial concentration

A limited number of investors finance a substantial portion of emerging technologies and may obtain strategic influence over competing firms.

3. Why Innovation Ecosystem Concentration Matters

Competition law traditionally protects the competitive process rather than individual competitors.

In innovation markets, however, future competition may be more important than present market shares.

A small start-up may currently have negligible revenue but possess technology capable of becoming a significant competitive constraint.

Consequently, concentration can affect:

1. innovation incentives;
2. R&D expenditure;
3. technological diversity;
4. entry by start-ups;
5. access to essential infrastructure;
6. availability of alternative technologies;
7. interoperability;
8. licensing conditions;
9. venture-capital opportunities;
10. future market structure.

4. Innovation Concentration and Article 101 TFEU

Article 101 TFEU can become relevant when firms within an innovation ecosystem coordinate their conduct.

Potential problems include:

• agreements restricting R&D;
• allocation of technological fields;
• restrictions on technology licensing;
• information exchange concerning future innovation;
• agreements not to compete in emerging technologies;
• joint standard-setting used to exclude competitors;
• coordinated refusal to license technology.

A technology collaboration is not automatically unlawful.

Joint R&D can generate substantial efficiencies because firms may pool:

• expertise;
• laboratories;
• capital;
• patents;
• data;
• research personnel.

The competition question is whether the arrangement unnecessarily removes independent competitive paths.

5. Innovation Ecosystem Concentration and Article 102 TFEU

Article 102 becomes particularly relevant where a dominant firm controls an ecosystem.

Potential abuses include:

Refusal to supply

A dominant infrastructure provider refuses access to an indispensable technological input.

Tying

A dominant platform requires innovators to use an additional proprietary service.

Exclusive dealing

Developers or suppliers are prevented from working with competing ecosystems.

Self-preferencing

The platform gives its own innovative products preferential access to infrastructure, data, rankings or distribution.

Interoperability restrictions

The dominant firm makes it difficult for competing technologies to interact with its ecosystem.

Margin squeeze

The firm imposes wholesale and retail conditions that make downstream competition commercially impracticable.

Predatory strategies toward innovators

A dominant incumbent may temporarily sacrifice profits to prevent an emerging technology from developing.

6. Innovation Ecosystem Concentration and Merger Control

Merger control is particularly important because ecosystem concentration may occur before a start-up becomes a significant competitor.

A traditional market-share analysis may underestimate the significance of an acquisition where:

• the target has little current revenue;
• the target has important intellectual property;
• the target possesses valuable data;
• the target is developing disruptive technology;
• the target could become a future competitor;
• the acquisition removes an independent innovation pathway.

This is closely related to the concept of potential competition.

Competition authorities may therefore examine:

What competitive constraint might the target have imposed if it remained independent?

7. Killer Acquisitions and Innovation Ecosystems

A killer acquisition generally describes an acquisition in which an incumbent purchases an emerging firm partly because the target could develop into a competitive threat.

The concern is particularly strong in:

• pharmaceuticals;
• biotechnology;
• AI;
• fintech;
• digital platforms;
• cloud computing;
• cybersecurity;
• semiconductor technology.

The target's current market share may be insignificant even though its technological potential is substantial.

Therefore, innovation ecosystem concentration requires consideration of dynamic competition, not merely current competition.

8. Relevant Case Laws

1. United States v. Microsoft Corp., 253 F.3d 34 (D.C. Cir. 2001)

The Microsoft case is one of the most important authorities concerning ecosystem-based technological power.

Microsoft possessed substantial power in the PC operating-system market and used various contractual and technological strategies involving web browsers.

The court examined conduct designed to protect Microsoft's operating-system position against potential competitive threats.

Relevance to innovation ecosystems

The case demonstrates that competition concerns can arise where a firm uses control over one technological layer to restrict competition in another.

It is particularly relevant to:

• platform ecosystems;
• technological integration;
• interoperability;
• exclusion of emerging technologies;
• protection of monopoly positions through complementary products.

The broader lesson is that competition law can examine ecosystem strategies rather than isolated products.

9. United States v. Google LLC, 2024 WL 4284459 (D.D.C. 2024)

The Google search case concerned Google's conduct relating to distribution and default arrangements for search.

The court found Google liable under U.S. antitrust law for unlawfully maintaining monopoly power in relevant search and search advertising markets.

Innovation ecosystem significance

The case demonstrates how control over distribution channels can reinforce technological and data advantages.

A dominant ecosystem can benefit from:

• user data;
• default positions;
• scale;
• distribution;
• advertiser relationships;
• technological feedback.

These advantages can reinforce one another.

The case is therefore relevant to the proposition that competition authorities may need to consider ecosystem feedback loops when evaluating durable technological dominance.

10. Google Shopping — Google and Alphabet v Commission, Case C-48/22 P

The EU Google Shopping litigation concerned Google's treatment of comparison-shopping services in its general search results.

The European Commission found that Google had abused its dominant position by favouring its own comparison-shopping service.

The General Court largely upheld the Commission's decision, and the Court of Justice subsequently dealt with Google's appeal.

Relevance

The case is important for understanding self-preferencing within an ecosystem.

A platform may simultaneously act as:

• infrastructure provider;
• intermediary;
• marketplace;
• distributor;
• competitor.

This creates a risk that control over infrastructure can be used to disadvantage independent innovators operating through that infrastructure.

11. Google Android — Google and Alphabet v Commission, Case C-738/22 P

The Android litigation concerned Google's contractual arrangements involving Android devices and applications.

The European Commission examined restrictions concerning:

• Google Search;
• Google Play Store;
• Android devices;
• competing search applications.

The case illustrates how ecosystem concentration can involve multiple interconnected products rather than a single market.

Competition-law significance

A dominant firm may reinforce its position through contractual arrangements connecting:

operating system + application store + search + device distribution.

Such arrangements can affect the ability of rival innovators to obtain distribution.

12. Intel Corp. v Commission, Case C-413/14 P

Intel concerned alleged exclusionary rebates offered by Intel to computer manufacturers and a major retailer.

The Court of Justice held that where the dominant undertaking submits evidence that its conduct was not capable of restricting competition, the Commission must assess the circumstances of the case, including the as-efficient-competitor test where appropriate.

Innovation ecosystem significance

The case is relevant because exclusionary conduct by a technologically powerful firm can affect the competitive opportunities available to rivals.

In innovation ecosystems, exclusion may occur through:

• rebates;
• incentives;
• preferential contracts;
• exclusivity;
• conditional discounts.

These practices can prevent competing technologies from reaching sufficient scale to become effective competitors.

13. Bronner v Mediaprint, Case C-7/97

The Bronner case concerned access to a newspaper home-delivery system.

The Court established stringent conditions for treating refusal of access to an infrastructure as an abuse of dominance.

The facility generally must be indispensable, and duplication must not be realistically possible under the relevant conditions.

Innovation ecosystem significance

The case is important when an innovation ecosystem depends upon infrastructure controlled by a dominant undertaking.

Examples include:

• cloud infrastructure;
• telecommunications networks;
• payment infrastructure;
• app distribution;
• technical interfaces;
• specialized technological facilities.

The case cautions against treating every refusal of access as an antitrust violation.

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

IMS Health concerned access to a copyrighted structure used for pharmaceutical sales data.

The Court considered when refusal to license intellectual property can constitute an abuse of dominance.

The Court identified demanding conditions concerning:

1. indispensability;
2. prevention of the emergence of a new product;
3. absence of objective justification;
4. elimination of competition in a secondary market.

Innovation ecosystem significance

The case is particularly important for ecosystems involving:

• proprietary data;
• software interfaces;
• intellectual property;
• technological standards.

It demonstrates that intellectual-property concentration does not automatically require compulsory access, but exceptional circumstances may justify intervention.

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

The EU Microsoft case concerned, among other matters, Microsoft's refusal to provide interoperability information and the tying of Windows Media Player with Windows.

The General Court substantially upheld the Commission's findings.

Relevance to innovation ecosystems

The case demonstrates how control over one technological layer can affect competition in complementary markets.

Interoperability is particularly important because independent innovators may depend upon access to technical information to make their products compatible with a dominant platform.

The case therefore provides an important foundation for analysing:

• API access;
• interoperability;
• technical documentation;
• platform compatibility;
• complementary innovation.

16. Magill — Joined Cases C-241/91 P and C-242/91 P

The Magill litigation concerned television programme listings and access to copyrighted information.

The Court recognized exceptional circumstances under which refusal to license intellectual property could constitute an abuse.

The case is important because it established a significant framework for analysing the relationship between:

intellectual property rights + market power + access + innovation.

For innovation ecosystems, the principle is relevant where proprietary information becomes an essential foundation for downstream innovation.

17. European Commission v Broadcom, AT.40608

The Broadcom investigation concerned contractual restrictions involving chipsets used in television set-top boxes and modems.

The Commission imposed interim measures addressing concerns regarding exclusivity and related contractual practices.

Ecosystem relevance

Semiconductor ecosystems illustrate how a firm controlling an important technological component can influence downstream equipment manufacturers.

A concentrated upstream technology layer may therefore produce effects throughout:

chipsets → devices → software → services → consumers.

18. Qualcomm — Qualcomm Inc. v Commission, Case T-235/18

The Qualcomm litigation concerned payments made to Apple and their potential exclusionary effects in the baseband chipset market.

The General Court annulled the Commission's decision, identifying significant shortcomings in the Commission's analysis.

Importance

The case illustrates that sophisticated technological markets require careful examination of:

• competitive effects;
• customer incentives;
• foreclosure;
• market structure;
• counterfactual competition.

It also demonstrates that an ecosystem theory of harm must be supported by evidence rather than merely by the existence of technological concentration.

19. Innovation Ecosystem Concentration and Data

Data can generate concentration through several mechanisms.

Network effects

More users generate more data.

Learning effects

More data may improve algorithms.

Scale effects

Better algorithms attract more users.

This can create a feedback loop:

users → data → better technology → more users → more data.

Competition concerns arise if competitors cannot obtain comparable inputs.

However, data possession alone does not necessarily establish dominance. Authorities must examine:

• substitutability;
• uniqueness;
• quality;
• access;
• replicability;
• switching costs;
• network effects.

20. Innovation Ecosystem Concentration and Standards

Technical standards can facilitate innovation by ensuring compatibility.

However, standards can also create competition concerns where:

• participation is controlled by incumbents;
• alternative technologies are excluded;
• standard-setting becomes a vehicle for collusion;
• intellectual property is strategically withheld;
• licensing terms discriminate against rivals.

Standard-setting therefore creates a dual competition-law question:

Does the standard facilitate interoperability, or does it become a mechanism for exclusion?

21. Innovation Ecosystem Concentration and APIs

APIs can be critical innovation infrastructure.

A dominant platform may control access to:

• user data;
• payment systems;
• identity systems;
• application functions;
• technical services;
• advertising infrastructure.

Potential competition issues arise if API access is:

• selectively denied;
• technically degraded;
• excessively priced;
• conditioned on exclusionary commitments;
• supplied preferentially to the platform's own services.

The Microsoft interoperability litigation provides an important conceptual foundation for this problem.
