Device Manufacturer Restrictions and Competition Effects

Introduction

Device manufacturer restrictions are contractual, technical, commercial, or ecosystem-based measures imposed by manufacturers of smartphones, tablets, computers, smart TVs, wearables, vehicles, IoT devices, or other connected hardware that limit how distributors, retailers, developers, component suppliers, service providers, or consumers may use, repair, modify, interoperate with, or distribute the device.

Such restrictions are not inherently anti-competitive. A manufacturer may legitimately impose restrictions to protect security, product quality, intellectual property, safety, interoperability, warranty integrity, or consumer experience. Competition concerns arise when restrictions are used by a firm with substantial market power to foreclose rivals, prevent switching, raise competitors' costs, restrict access to complementary markets, or extend dominance from hardware into software and services.

The legal analysis commonly involves abuse of dominance/monopolisation, exclusive dealing, tying and bundling, refusal to supply, discriminatory access, interoperability restrictions, vertical restraints, aftermarket restrictions, and merger-related ecosystem effects.

1. Meaning and Scope of Device Manufacturer Restrictions

Device manufacturer restrictions can include:

1. Pre-installation restrictions – requiring particular apps or services to be installed by default.
2. Default-setting restrictions – preventing users or distributors from changing defaults.
3. App-store restrictions – requiring developers to use a particular distribution or payment system.
4. API restrictions – withholding technical interfaces from competing applications.
5. Interoperability restrictions – preventing devices from communicating with competing products.
6. Accessory certification restrictions – limiting compatible accessories to approved suppliers.
7. Repair restrictions – restricting access to parts, diagnostic software, firmware, or repair tools.
8. Warranty restrictions – linking warranty coverage to authorised components or repair networks.
9. Firmware/bootloader restrictions – preventing modification or installation of alternative operating systems.
10. Developer licensing restrictions – limiting software development or distribution.
11. Carrier restrictions – contractual limitations on network compatibility or device unlocking.
12. Data-access restrictions – restricting competitors' access to device-generated data.
13. NFC/Bluetooth/USB restrictions – limiting access to technically important functionality.
14. Anti-steering restrictions – preventing developers or retailers from directing users toward alternative purchasing channels.
15. Exclusive distribution arrangements – restricting where or how devices or related services can be sold.

2. Why Device Restrictions Can Affect Competition

The central competition concern is that a device manufacturer may control a gateway between consumers and adjacent markets.

For example:

Hardware → Operating System → App Distribution → Payments → Data → Advertising → Cloud/Services

If one company controls several layers, a restriction at the hardware or operating-system level can affect competition in downstream markets.

Possible effects

A. Foreclosure of competitors

A manufacturer may prevent competing software or services from obtaining access to the device's functionality.

B. Raising rivals' costs

Competitors may have to develop expensive workarounds because the manufacturer withholds APIs, technical specifications, or interoperability.

C. Switching costs

Restrictions may make it difficult for consumers to move from one ecosystem to another.

D. Network effects

A large installed device base can attract developers and service providers, which increases the attractiveness of the ecosystem and potentially reinforces the manufacturer's position.

E. Leveraging

A manufacturer dominant in devices or operating systems may use restrictions to strengthen a position in another market, such as payments, search, advertising, cloud services, or content distribution.

F. Reduced innovation

If third-party developers cannot access important technical functions, alternative products may never develop.

G. Consumer harm

Potential consequences include:

• fewer choices;
• higher prices;
• reduced quality;
• less innovation;
• reduced privacy alternatives;
• reduced repair options;
• increased switching costs.

However, these effects must be demonstrated rather than presumed.

3. Relevant Competition-Law Theories

A. Abuse of Dominance

Where the manufacturer possesses substantial market power, restrictions may constitute abusive conduct if they exclude competitors or exploit customers.

The analysis generally requires consideration of:

• relevant product and geographic market;
• dominance or monopoly power;
• nature of the restriction;
• foreclosure;
• duration;
• actual or likely competitive effects;
• efficiencies and legitimate justifications.

B. Exclusive Dealing

A manufacturer may require distributors, retailers, developers, or service providers to deal exclusively with its ecosystem.

Exclusive arrangements become particularly significant when the manufacturer controls an important access point and competing suppliers cannot readily reach customers through alternative channels.

C. Tying and Bundling

A manufacturer may make access to one product conditional upon acceptance of another.

Examples include:

• device + search service;
• operating system + browser;
• operating system + payment service;
• device + app store;
• device + cloud service.

The competition issue is whether the arrangement forecloses competitors in the tied market.

4. Refusal of Access and Interoperability

Some device ecosystems depend on technical interoperability.

A manufacturer may control:

• APIs;
• authentication;
• device pairing;
• NFC;
• Bluetooth profiles;
• messaging protocols;
• application programming interfaces;
• accessory certification;
• software-development kits.

A refusal to provide access can become particularly important where the technical facility is difficult or impossible for competitors to replicate.

Competition law does not, however, generally require dominant companies to share every proprietary technology with competitors. The circumstances surrounding the refusal are critical.

5. Aftermarket Restrictions

Device restrictions can create an aftermarket problem.

A consumer may purchase a primary product and subsequently become dependent on the manufacturer's:

• spare parts;
• software updates;
• repair services;
• accessories;
• consumables;
• diagnostic tools;
• cloud services.

The manufacturer may then impose restrictions after the initial purchase.

The legal question may be whether consumers were adequately informed before purchasing the device and whether the manufacturer possesses market power in the aftermarket.

6. Six Major Case Laws

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

Facts

Microsoft possessed monopoly power in the market for Intel-compatible PC operating systems. It imposed various restrictions affecting computer manufacturers, software developers, and competing technologies, particularly competing browsers.

Competition principle

The case demonstrated how contractual and technical restrictions imposed by a dominant technology platform can be examined as exclusionary conduct.

Microsoft's agreements and technical practices were assessed collectively in the context of its monopoly position and their effect on competing technologies.

Relevance to device manufacturers

The case is highly relevant to modern device ecosystems because manufacturers may use:

• contractual restrictions;
• technical integration;
• default settings;
• access restrictions;
• software integration;

to protect or extend an ecosystem position.

Key lesson

Technical control combined with contractual restrictions can produce exclusionary effects when exercised by a monopolist.

2. European Commission — Google Android, Case AT.40099 (2018)

Facts

The European Commission examined Google's conduct concerning the Android operating system, including agreements involving:

• Google Search;
• Google Play;
• Chrome;
• device manufacturers;
• mobile network operators.

The Commission found several practices restrictive of competition, including arrangements involving pre-installation and licensing.

Competition principle

The case illustrates how an operating-system provider can use contractual restrictions and pre-installation requirements to influence competition in adjacent digital markets.

Relevance to device manufacturers

Device manufacturers may function as the distribution channel through which users obtain competing:

• search engines;
• browsers;
• applications;
• services.

Restrictions affecting what manufacturers can pre-install or distribute can therefore affect downstream competition.

Key lesson

Control over the operating-system/device layer can provide leverage into neighbouring digital markets.

3. European Commission — Google Search (Shopping), Case AT.39740

Although this case did not concern device restrictions directly, it is relevant to the broader concept of leveraging dominance through a controlled digital interface.

Facts

The European Commission examined Google's treatment of competing comparison-shopping services within its search results.

Competition principle

A dominant platform's control over an important access point can materially influence the ability of competing services to reach consumers.

Relevance to device ecosystems

The same conceptual problem can arise where a device manufacturer controls:

• home-screen placement;
• default applications;
• search access;
• app discovery;
• recommendation interfaces.

Key lesson

Control over an important consumer-access interface can have competitive significance beyond the market in which the interface itself operates.

4. European Commission — Apple App Store Practices / Apple–App Store investigations

The European Commission's investigations into Apple's App Store practices concern restrictions imposed on developers using Apple's mobile ecosystem.

Competition issues

Relevant practices have included restrictions concerning:

• alternative payment mechanisms;
• steering consumers;
• distribution;
• commissions;
• access to Apple's ecosystem.

Relevance to device manufacturers

This illustrates a modern form of device ecosystem restriction where the hardware manufacturer is also the operator of:

device + operating system + app store + payment infrastructure.

The competitive concern is that control over one layer can affect competition in another.

Key lesson

Vertical integration does not itself establish an infringement, but restrictions imposed by an integrated ecosystem operator can have effects across multiple connected markets.

5. Epic Games, Inc. v. Apple Inc. — 559 F. Supp. 3d 898 (N.D. Cal. 2021)

Facts

Epic challenged Apple's App Store rules concerning distribution and payment systems.

The litigation examined Apple's control over iOS app distribution and its restrictions on developers' ability to use alternative payment mechanisms and direct users toward alternative purchasing arrangements.

Competition significance

The case illustrates the importance of:

• platform access;
• app distribution;
• payment restrictions;
• anti-steering provisions;
• developer dependency.

Device-manufacturer relevance

A device manufacturer that operates the dominant application-distribution system can effectively control access to consumers.

Key lesson

App-store rules can become competition-law issues when access to a device ecosystem is commercially indispensable or when restrictions materially affect alternative distribution or payment channels.

6. Qualcomm Inc. v. Federal Trade Commission — 969 F.3d 974 (9th Cir. 2020)

Facts

The FTC challenged aspects of Qualcomm's licensing practices relating to cellular standard-essential patents and modem-chip markets.

The Ninth Circuit ultimately rejected the FTC's Sherman Act theory on the record presented.

Relevance

The case is important because it demonstrates that commercial restrictions and powerful technological positions do not automatically amount to antitrust violations.

The court emphasised the need for an appropriate antitrust theory connecting the challenged conduct to competitive harm.

Device-manufacturer relevance

Modern devices depend on critical technologies such as:

• cellular standards;
• chips;
• connectivity;
• wireless communications.

Manufacturers and technology suppliers can possess significant bargaining power without every contractual restriction becoming unlawful.

Key lesson

Competition law requires a demonstrated connection between the challenged restriction and cognisable competitive harm.

7. Additional Important Authorities

7. Apple v. Pepper — 587 U.S. 273 (2019)

The U.S. Supreme Court allowed consumers to pursue antitrust claims concerning Apple's App Store under the direct-purchaser rule.

The case is significant for understanding the relationship between platform operators, developers, consumers, and distribution channels.

8. Ohio v. American Express Co. — 585 U.S. 529 (2018)

The Supreme Court examined anti-steering provisions in a two-sided transaction platform.

Although not a device case, the reasoning is relevant to ecosystems because restrictions preventing one side of a platform from directing users toward alternatives can affect competition.

9. FTC v. Qualcomm Inc. — Ninth Circuit

The Qualcomm litigation is particularly important for distinguishing between:

• contractual restrictions;
• intellectual-property licensing;
• market power;
• exclusionary conduct.

It demonstrates why the existence of a restrictive commercial practice does not, standing alone, establish antitrust liability.

8. Device Restrictions and the "Walled Garden"

A walled garden occurs where a manufacturer creates an ecosystem in which users and developers are strongly encouraged—or technically required—to remain within the manufacturer's infrastructure.

Typical elements include:

Device

↓

Operating System

↓

App Store

↓

Payment System

↓

Cloud Account

↓

Data

↓

Accessories

↓

Repair Network

The more layers controlled by one firm, the greater the possibility that a restriction at one layer will affect competition elsewhere.

But vertical integration itself is not unlawful.

The important question is how the integration is used and what competitive effects result.

9. Technical Restrictions

Technical restrictions can sometimes be more significant than contractual restrictions.

Examples include:

API blocking

Competitors are denied access to functionality available to the manufacturer's own services.

Authentication restrictions

Only approved services can authenticate with the device.

Firmware restrictions

Alternative operating systems or applications cannot operate.

Bootloader restrictions

Users cannot install alternative software.

Interoperability degradation

Third-party devices technically connect but receive inferior functionality.

Certification requirements

Competitors must satisfy costly or discriminatory certification procedures.

Data-access restrictions

Competitors cannot obtain data necessary to provide competing services.

These practices can raise competition concerns where they substantially impair rivals' ability to compete.

10. Repair and Parts Restrictions

Device manufacturers may restrict:

• access to spare parts;
• diagnostic software;
• repair manuals;
• firmware;
• calibration systems;
• proprietary tools.

Competition analysis can arise in aftermarkets for repair and maintenance.

Relevant questions include:

1. Does the manufacturer have substantial power over the device aftermarket?
2. Were consumers informed of the restrictions?
3. Are independent repairers realistically able to compete?
4. Is there a legitimate security or safety justification?
5. Are restrictions proportionate?
6. Do the restrictions prevent interoperability?
7. Are consumers effectively locked into the manufacturer's service network?

11. Accessory Restrictions

Manufacturers sometimes create certification programs for:

• chargers;
• headphones;
• batteries;
• smart watches;
• cases;
• controllers;
• vehicle accessories;
• medical-device interfaces.

Certification can be legitimate where it ensures safety or compatibility.

Competition concerns may arise where certification:

• is unnecessarily expensive;
• is discriminatory;
• is selectively withheld;
• excludes technically compatible rivals;
• protects the manufacturer's accessory business.

12. Data Restrictions

Modern devices generate large quantities of data:

• location;
• usage;
• diagnostics;
• battery condition;
• sensor data;
• performance information;
• behavioural information.

If competitors require this information to provide competing services, restrictions on data access can potentially become a competition issue.

This is particularly important for:

• connected cars;
• smart homes;
• wearables;
• industrial IoT;
• healthcare devices.

13. Consumer Switching Costs

Device restrictions can increase switching costs through:

• proprietary accessories;
• incompatible applications;
• proprietary data formats;
• cloud dependence;
• account lock-in;
• loss of purchased content;
• messaging incompatibility;
• proprietary payments;
• device-specific services.

Competition authorities may therefore examine actual switching behaviour, not merely the nominal ability to purchase a rival device.

14. Legitimate Business Justifications

Manufacturers can have legitimate reasons for restrictions.

Security

Opening an API or allowing unrestricted software installation may increase cybersecurity risks.

Safety

Medical devices, vehicles, batteries, and industrial equipment may require strict certification.

Quality control

Manufacturers may need to ensure compatibility.

Intellectual property

A manufacturer may legitimately protect proprietary technology.

Privacy

Restrictions can sometimes prevent unauthorised access to personal data.

Consumer protection

Manufacturers may impose restrictions to prevent defective or unsafe third-party components.

Consequently, competition analysis should distinguish legitimate product design from exclusionary conduct.

15. Effects on Innovation

Restrictions can produce two opposite effects.

Potentially harmful

They may prevent:

• competing applications;
• independent repair;
• alternative accessories;
• interoperable devices;
• new business models.

Potentially beneficial

They may promote:

• cybersecurity;
• reliability;
• product quality;
• compatibility;
• investment in proprietary technology.

Therefore, competition law generally requires an effects-based assessment rather than assuming that every restriction is harmful.

16. Competition-Law Analytical Framework

A useful framework is:

Step 1 — Define the market

Possible markets include:

• smartphones;
• operating systems;
• app distribution;
• mobile payments;
• device repair;
• accessories;
• cloud services;
• connected-car services.

Step 2 — Determine market power

Consider:

• market shares;
• entry barriers;
• network effects;
• switching costs;
• ecosystem control;
• technical advantages;
• data advantages.

Step 3 — Identify the restriction

Is it:

• contractual?
• technical?
• discriminatory?
• exclusive?
• tying?
• interoperability-related?
• data-related?

Step 4 — Identify affected rivals

Determine which competitors are prevented from:

• entering;
• expanding;
• reaching users;
• interoperating;
• obtaining data;
• distributing products.

Step 5 — Establish competitive effects

Assess:

• foreclosure;
• prices;
• quality;
• innovation;
• consumer choice;
• switching;
• entry.

Step 6 — Examine justification

Ask whether the restriction produces legitimate efficiencies.

Step 7 — Consider proportionality

Could substantially the same legitimate objective be achieved through a less restrictive alternative?

17. Case-Law Principles Compared

18. Indian Competition-Law Perspective

In India, device manufacturer restrictions can potentially be examined under the Competition Act, 2002, particularly provisions concerning:

• Section 3 — anti-competitive agreements;
• Section 4 — abuse of dominant position;
• relevant vertical restraints under Section 3(4);
• tying and bundling;
• exclusive supply/distribution;
• refusal to deal;
• denial of market access;
• leveraging.

The Competition Commission of India has increasingly examined technology ecosystems, digital platforms, app stores, interoperability, and restrictions affecting downstream markets.

The central distinction remains:

A restrictive business practice is not necessarily unlawful merely because it limits commercial freedom; competition law focuses on whether the practice produces the legally relevant anti-competitive effect and whether the firm possesses the requisite market power.

19. Emerging Issues

Device manufacturers are increasingly becoming ecosystem operators, creating new competition questions concerning:

AI-enabled devices

Manufacturers may control access to on-device AI models and assistants.

Automotive ecosystems

Vehicle manufacturers can control:

• charging interfaces;
• telematics;
• navigation;
• vehicle data;
• software updates;
• repair systems.

Wearables

Smartwatch manufacturers may restrict interoperability with competing phones or health platforms.

Smart homes

Manufacturers may limit interoperability with competing:

• speakers;
• cameras;
• locks;
• thermostats;
• security systems.

Right-to-repair

Restrictions on independent repair may affect competition in repair aftermarkets.

Digital identity

Device manufacturers increasingly control authentication and identity infrastructure.

Device-generated data

Control over sensor and usage data may create new competitive advantages.

Conclusion

Device manufacturer restrictions occupy an important intersection between hardware competition and digital-platform competition. A manufacturer can influence competition not only through the sale of devices but also through control over operating systems, app distribution, payment systems, APIs, accessories, data, repair infrastructure, and interoperability.

The principal competition-law concern arises when a manufacturer with substantial market power uses these restrictions to exclude rivals, foreclose market access, increase switching costs, discriminate against competing services, or leverage power into adjacent markets.

The principal countervailing consideration is that restrictions can also serve legitimate purposes involving security, safety, privacy, intellectual property, quality, and interoperability.
