1. Introduction

Device lifecycle control refers to the ways in which a manufacturer or technology platform manages a device from design and launch through updates, upgrades, repair, replacement, support, interoperability, and eventual end-of-life.

In ordinary commercial terms, lifecycle management is legitimate. Manufacturers need to decide when to introduce new models, discontinue obsolete components, provide security updates, modify software, and stop supporting products.

Competition-law concerns arise when lifecycle decisions are used strategically to extend or protect market power, particularly where users become dependent on a particular device ecosystem and competitors cannot realistically enter associated aftermarkets.

Typical strategies include:

1. restricting spare parts;
2. limiting repair tools or diagnostic software;
3. discontinuing software/security support;
4. making older devices incompatible with new software;
5. designing devices to reject third-party components;
6. using proprietary interfaces or authentication;
7. tying replacement components to the original manufacturer;
8. controlling firmware and operating-system updates;
9. making interoperability progressively more difficult;
10. encouraging replacement rather than repair;
11. using warranties or contractual restrictions to channel consumers toward authorised services; and
12. controlling the timing of product retirement.

The central legal question is not simply whether a manufacturer shortens a product's life. The important question is whether lifecycle control produces an exclusionary effect in a relevant market, particularly an aftermarket for repairs, spare parts, software, accessories, maintenance, upgrades or compatible devices.

2. Meaning of Device Lifecycle Control Strategies

A device normally passes through several stages:

Design → Launch → Adoption → Updates → Repair/Upgrade → Mature aftermarket → Support reduction → End-of-life → Replacement

At each stage, the manufacturer can exercise different forms of control.

A. Design-stage control

The manufacturer may decide:

• whether components are replaceable;
• whether batteries are removable;
• whether third-party parts can operate;
• whether repair information is publicly available;
• whether diagnostic interfaces are open;
• whether firmware authenticates replacement components.

B. Software-support control

The manufacturer controls:

• operating-system updates;
• security patches;
• firmware;
• API access;
• compatibility;
• cloud services;
• device authentication.

A device may remain physically functional while becoming commercially obsolete because essential software services disappear.

C. Repair-market control

The manufacturer may control:

• genuine spare parts;
• diagnostic equipment;
• repair manuals;
• software keys;
• calibration tools;
• firmware access;
• technical information.

This can create a brand-specific repair aftermarket.

D. Upgrade control

Manufacturers may encourage users to purchase a newer device by:

• restricting features on older models;
• discontinuing upgrades;
• limiting compatibility;
• changing accessory standards;
• making new software unavailable;
• reducing functionality through updates.

Not every such practice is unlawful. The competition analysis depends heavily upon market power, consumer expectations, foreclosure, efficiencies and the availability of alternatives.

3. Principal Device Lifecycle Control Strategies

3.1 Planned or Accelerated Obsolescence

A manufacturer may deliberately design a device so that its useful economic life is relatively short.

Examples include:

• short software-support periods;
• non-replaceable batteries;
• proprietary components;
• unavailable spare parts;
• incompatible successor software.

From a competition-law perspective, obsolescence itself is not automatically an abuse. The issue becomes more serious when a dominant firm uses obsolescence to prevent competitors from supplying repair, refurbishment or upgrade services.

3.2 Spare-Part Restriction

A manufacturer may restrict access to:

• screens;
• batteries;
• processors;
• circuit boards;
• sensors;
• proprietary connectors;
• replacement modules.

This can make independent repair businesses dependent upon the manufacturer.

The classic legal principle is found in Eastman Kodak, where restrictions concerning parts and servicing were examined separately from the competitive conditions in the original equipment market.

4. Case Law

Case 1 — Eastman Kodak Co. v. Image Technical Services, Inc., 504 U.S. 451 (1992)

Facts

Kodak manufactured copying and micrographic equipment. Independent service organisations serviced Kodak machines.

Kodak subsequently adopted policies restricting the availability of replacement parts to independent service organisations.

The independent service organisations alleged that Kodak was using its position in equipment to control the aftermarket for:

• replacement parts; and
• servicing.

Legal principle

The U.S. Supreme Court rejected the proposition that competition in the primary equipment market automatically prevents market power in the aftermarket.

The Court recognised that consumers can become locked into a particular brand after purchasing equipment because of:

• sunk costs;
• information costs;
• switching costs;
• specialised parts; and
• specialised servicing requirements.

The Court therefore allowed the aftermarket theory to proceed.

Relevance to device lifecycle control

This is arguably the foundational case for analysing lifecycle control.

A smartphone, printer, medical device, industrial machine or IoT product can generate a separate aftermarket for:

device → spare parts → maintenance → repair → software support.

Thus, a manufacturer cannot necessarily argue:

"There are many competitors in the market for devices, therefore we cannot possess aftermarket power."

Principle

Primary-market competition does not automatically eliminate aftermarket power.

5. Case 2 — Shamsher Kataria v. Honda Siel Cars India Ltd. & Ors. (CCI, 2014)

This is particularly important from an Indian Competition Act, 2002 perspective.

Facts

The Competition Commission of India examined practices concerning automobile manufacturers and their control over:

• spare parts;
• diagnostic tools;
• technical information;
• repair and maintenance;
• authorised dealers;
• independent repairers.

The investigation treated the aftermarket for particular automobile brands as potentially distinct from the primary automobile market.

Findings and significance

The CCI examined whether automobile manufacturers possessed substantial power in brand-specific aftermarkets because independent repairers could not easily obtain:

• genuine spare parts;
• diagnostic equipment;
• technical manuals;
• software;
• fault codes.

The case therefore recognised the importance of technical dependency and brand-specific aftermarkets.

Application to devices

The same reasoning can apply to:

• smartphones;
• laptops;
• smart appliances;
• medical equipment;
• industrial robots;
• connected vehicles;
• IoT equipment.

For example, if a manufacturer controls the only practical source of firmware keys and diagnostic software necessary to repair a device, the manufacturer may have substantial control over the downstream repair ecosystem.

Key principle

Control over technical information and repair inputs can become an important source of aftermarket power.

6. Case 3 — Microsoft Corp. v. Commission, Case T-201/04

Facts

Microsoft was found to have abused its dominant position in relation to client PC operating systems.

Among the practices considered was Microsoft's integration of Windows Media Player with its dominant operating-system product.

The General Court examined the relationship between the dominant operating system and the adjacent media-player market.

Legal significance

The case demonstrates that control of a technological platform can be leveraged into adjacent markets.

The relevant concern was not merely the existence of an integrated product. Rather, the competition analysis considered whether the dominant firm's conduct could:

• restrict competing products;
• reinforce the dominant position;
• reduce consumer choice; and
• foreclose competitors.

Application to device lifecycle strategies

A modern device manufacturer may similarly control:

hardware + operating system + firmware + application ecosystem + accessories.

Lifecycle decisions concerning one component can therefore affect several neighbouring markets.

For example:

A manufacturer may discontinue an old operating-system version while simultaneously making third-party accessories or applications incompatible with the old device.

The competition issue would be whether this is an ordinary product-development decision or a strategy that unlawfully forecloses competitors.

Key principle

Control over a technological platform can be leveraged into related markets where compatibility and interoperability are commercially important.

7. Case 4 — Static Control Components, Inc. v. Lexmark International, Inc., 387 F.3d 522 (6th Cir. 2004)

Facts

Lexmark manufactured printers and toner cartridges.

Lexmark introduced technological measures involving microchips that prevented printers from accepting certain third-party or remanufactured cartridges.

Static Control developed chips that facilitated the production of compatible remanufactured cartridges.

Lexmark attempted to use copyright and technological-control arguments against Static Control.

The subsequent litigation also involved antitrust theories concerning Lexmark's control over cartridge aftermarkets. The Sixth Circuit later discussed claims involving Lexmark's Prebate programme and technological exclusion.

Competition significance

This case illustrates a particularly important lifecycle-control strategy:

technical authentication of replacement components.

A manufacturer can theoretically make a device accept only:

• authorised cartridges;
• authorised batteries;
• authorised screens;
• authorised processors;
• authorised software;
• authorised repair components.

Application

Device authentication can be legitimate where it protects:

• safety;
• cybersecurity;
• quality;
• intellectual property;
• regulatory compliance.

But where authentication is used primarily to prevent otherwise lawful competing replacement products, it can raise competition concerns.

Key principle

Technological compatibility mechanisms can influence competition in device-specific aftermarkets.

8. Case 5 — Static Control Components, Inc. v. Lexmark International, Inc., 572 F. Supp. 2d / subsequent Sixth Circuit litigation

The broader Static Control–Lexmark litigation is useful because it demonstrates the complexity of applying aftermarket theories to lifecycle control.

Lexmark used a combination of:

• single-use cartridge restrictions;
• microchips;
• patent rights;
• copyright claims;
• technological compatibility measures.

The Sixth Circuit noted that allegations involving redesigned microchips intended to exclude competitors had to be analysed carefully rather than automatically being treated as antitrust violations.

Importance

This litigation demonstrates an essential limitation:

Not every technological restriction that makes third-party products more difficult to use constitutes unlawful monopolisation.

The claimant must establish the relevant legal elements, including appropriate market definition, market power and competitive harm.

Device lifecycle lesson

A manufacturer may legitimately redesign a product.

The competition concern becomes stronger where:

redesign → incompatibility → exclusion of existing aftermarket competitors → increased dependence → reduced competition

is supported by evidence of exclusionary intent/effect and market power.

9. Case 6 — United States v. International Business Machines Corp., 163 F.3d 737 (2d Cir. 1998)

Facts

IBM had historically been subject to restrictions concerning the supply of computer spare parts and maintenance.

The litigation surrounding termination of the relevant decree examined whether independent maintenance providers could continue competing in the market.

The Second Circuit considered the existence of an active secondary market for spare parts and maintenance and the importance of continued access to components.

Relevance

The case demonstrates why lifecycle control cannot be examined only at the point of initial device sale.

A sophisticated technological product creates an ecosystem lasting many years.

Competition may exist not only between manufacturers of new devices but also among:

• maintenance providers;
• repair companies;
• component suppliers;
• refurbished-device sellers;
• independent service organisations.

Key principle

Maintaining access to necessary spare parts can be important for preserving downstream competition.

10. Case 7 — Oracle America, Inc. v. Hewlett Packard Enterprise Co. (9th Cir. 2020)

Facts

The dispute concerned Oracle's Solaris operating system and access to software patches for servers.

Oracle's licensing/support structure required customers to maintain support arrangements to obtain patches, while HPE provided support services involving Solaris systems.

Although the litigation principally concerned copyright and related claims rather than establishing an antitrust violation, it is useful for understanding the legal significance of software-support control.

Lifecycle significance

Modern devices increasingly depend on:

• firmware;
• operating systems;
• patches;
• cloud authentication;
• security updates.

Consequently, "ownership" of a physical device does not necessarily mean that the user controls its complete technological lifecycle.

Competition implication

A dominant manufacturer may potentially use control over:

updates → patches → authentication → continued functionality

to strengthen its position in:

• support;
• maintenance;
• accessories;
• cloud services;
• replacement products.

The legal analysis would depend on the applicable competition-law framework and evidence of exclusionary conduct.

11. Case 8 — Apple iPhone Battery/Performance Management Investigation — UK CMA

Although this was a consumer-protection enforcement matter rather than a competition-law judgment, it is highly relevant to device lifecycle control.

The UK Competition and Markets Authority investigated concerns about Apple iPhones and the effect of software updates on battery-related performance.

Apple ultimately gave undertakings concerning clearer information about:

• battery health; and
• the effect of performance-management software. 

Lifecycle relevance

This demonstrates the legal significance of software intervention in the physical lifecycle of a device.

A software update can change:

battery condition → device performance → perceived useful life → replacement decision.

Competition-law connection

If a dominant manufacturer deliberately uses software controls to make older devices less competitive with newer products, several legal questions can arise:

1. Is the conduct objectively justified?
2. Does it improve safety?
3. Does it protect battery integrity?
4. Was adequate information supplied?
5. Are consumers effectively locked into replacement?
6. Does the practice exclude competing repair or replacement services?

The Apple investigation itself should not be treated as establishing an antitrust violation.

12. Case 9 — Apple Inc. Smartphone Antitrust Litigation, United States

The U.S. Department of Justice's 2024 antitrust case against Apple alleges that Apple used various restrictions concerning access to iPhone functionality, including restrictions affecting interoperability with third-party applications and accessories. The case concerns alleged monopolisation and exclusionary conduct; it is not a final judicial finding of liability.

Lifecycle significance

The allegations illustrate how a modern device lifecycle extends beyond the physical device.

Apple's ecosystem can be conceptualised as:

iPhone → iOS → APIs → applications → accessories → cloud services → replacement device

Control at one stage can influence competitive conditions at another.

Relevance

This is particularly important for future device markets where:

• hardware;
• software;
• APIs;
• accessories;
• cloud accounts; and
• identity systems

are increasingly integrated.

13. Comparative Table of the Principal Cases

14. Major Forms of Lifecycle Manipulation

A. Component Lock-In

The manufacturer makes replacement parts available only through its own network.

Effect:

Device ownership → manufacturer-controlled repair → reduced independent repair competition.

B. Software Lock-In

The manufacturer refuses to provide updates, APIs, firmware or diagnostic software to independent providers.

This can create a software-controlled aftermarket.

C. Authentication Lock-In

The device verifies whether a component is authorised.

Examples:

• battery serial-number pairing;
• display authentication;
• motherboard authentication;
• cartridge chips;
• cloud activation.

This can make otherwise technically functional replacement components unusable.

D. Compatibility Obsolescence

A new software version works only on newer hardware.

The result can be:

new software → old device excluded → consumer replacement → increased demand for new devices.

This may be commercially legitimate where technical limitations justify it, but can raise competition concerns where exclusion is strategic.

E. Repair Information Control

Manufacturers may restrict:

• repair manuals;
• diagnostic codes;
• calibration information;
• firmware tools;
• error logs;
• component specifications.

Such information can constitute an important input into independent repair.

15. Device Lifecycle Control and Relevant Markets

A major analytical problem is market definition.

There may be several interconnected markets:

Primary market

Smartphones

Secondary market

Smartphone repair

Component aftermarket

Replacement batteries

Technical aftermarket

Diagnostic software

Software aftermarket

Operating-system support

Service aftermarket

Maintenance and repair

Refurbishment market

Used/refurbished devices

A lifecycle-control strategy may therefore affect several markets simultaneously.

The Kodak principle is particularly important because a competitive primary market does not necessarily eliminate the possibility of market power in an aftermarket.

16. Network Effects and Lifecycle Control

Lifecycle control becomes more powerful when combined with network effects.

For example:

Device adoption

↓

Developer adoption

↓

Application ecosystem

↓

Accessory ecosystem

↓

User dependence

↓

Higher switching costs

↓

Greater lifecycle control

The manufacturer may consequently have greater ability to influence replacement decisions.

17. Switching Costs

Lifecycle strategies become particularly significant where consumers have accumulated:

• purchased applications;
• data;
• accessories;
• subscriptions;
• device-specific knowledge;
• cloud storage;
• digital identities;
• proprietary files;
• connected-home configurations.

The economic cost of switching may therefore substantially exceed the price of the new device.

This strengthens the relevance of aftermarket analysis.

18. Planned Obsolescence vs Legitimate Product Evolution

A crucial distinction must be maintained.

Legitimate product evolution may include:

• improved security;
• new hardware standards;
• better energy efficiency;
• technical incompatibility;
• safety improvements;
• genuine technological advancement;
• discontinued production of obsolete components.

Potentially problematic lifecycle conduct may include:

• deliberately disabling competing replacement parts;
• withholding essential diagnostic information;
• unjustified restriction of independent repairs;
• discriminatory access to firmware;
• tying repairs to new-device purchases;
• artificially reducing interoperability;
• using proprietary authentication solely to exclude competitors.

The presence of one of these practices does not by itself establish an antitrust violation.

19. Objective Justifications

A manufacturer may have legitimate reasons for lifecycle controls.

These can include:

Safety

A poorly manufactured replacement component may create risks.

Cybersecurity

Open firmware access could create vulnerabilities.

Quality control

Manufacturers may wish to ensure that repairs meet technical specifications.

Intellectual property

Some information may legitimately be protected.

Regulatory compliance

Medical, automotive or telecommunications equipment may require controlled modifications.

Innovation

Manufacturers must retain the ability to develop improved products.

Therefore, competition authorities generally need to distinguish genuine product improvement from exclusionary lifecycle management.

20. Competition-Law Tests

Where a dominant undertaking is involved, investigators may ask:

1. Is there dominance?

Relevant factors may include:

• market share;
• entry barriers;
• switching costs;
• network effects;
• technological dependency;
• brand-specific compatibility.

2. Is there an aftermarket?

For example:

• repair;
• maintenance;
• spare parts;
• software support;
• accessories.

3. Can the manufacturer control access?

For example:

• APIs;
• diagnostic tools;
• firmware;
• authentication;
• parts.

4. Are competitors foreclosed?

Would independent repairers or component manufacturers realistically be able to compete?

5. Is consumer choice reduced?

Consider:

• higher repair prices;
• fewer repair providers;
• reduced device lifespan;
• forced replacement;
• fewer compatible accessories.

6. Is there an objective justification?

Security, safety and technical necessity may be relevant.

7. Are less restrictive alternatives available?

For example:

• certification instead of prohibition;
• safety testing instead of component blocking;
• controlled API access instead of complete denial.

21. Device Lifecycle Control as a Leveraging Strategy

The most important economic theory can be represented as:

Primary Device Market

↓

Installed Base

↓

Consumer Lock-In

↓

Aftermarket Dependence

↓

Control of Parts / Software / Repairs

↓

Foreclosure of Independent Providers

↓

Higher Switching Costs

↓

Strengthening of Original Market Power

This is why lifecycle management can become an important competition-law issue.

22. Relationship With Right-to-Repair

Device lifecycle control is closely related to the right-to-repair debate.

Competition concerns arise when a manufacturer controls all of:

parts + tools + software + information + certification + repair network.

Independent repairers may then be unable to compete even though consumers technically own the physical device.

The U.S. DOJ and FTC have expressly recognised that restrictions on access to software and data necessary for repair can potentially restrict competition in replacement-parts and repair markets.

23. Security Updates as a Lifecycle Obligation

Modern lifecycle control cannot be understood only through physical components.

For connected devices:

Security update → device safety → continued functionality → continued commercial usefulness

The FTC's D-Link enforcement illustrates the importance of ongoing security management. D-Link agreed to implement security planning, testing, vulnerability remediation and automatic firmware updates for covered devices.

This illustrates that the device lifecycle can continue long after physical sale.

24. Abuse Through End-of-Life Decisions

An especially important strategy is strategic end-of-life.

A manufacturer may announce:

"This product is no longer supported."

The competition analysis should ask:

• Were consumers informed at purchase?
• Are replacement parts still available?
• Is software support still technically feasible?
• Does the manufacturer remain dominant?
• Are independent alternatives available?
• Does discontinuation affect competitors?
• Are users forced to purchase a new product?
• Does the manufacturer simultaneously restrict refurbishment?

The end-of-life decision itself is not automatically unlawful.

Its competitive significance depends upon market power and exclusionary effects.

25. Economic Effects

Potential harmful effects include:

Higher prices

Consumers may have to purchase manufacturer-provided parts.

Reduced repair competition

Independent repairers may exit.

Shorter economic device life

Consumers replace products earlier.

Increased switching costs

Users become more dependent on the manufacturer's ecosystem.

Reduced innovation

Independent developers and repair businesses may have less incentive to innovate.

Increased e-waste

Premature replacement can increase discarded devices, although environmental effects alone do not establish an antitrust violation.

26. Defences Available to Manufacturers

A manufacturer can potentially argue that lifecycle restrictions are justified by:

1. cybersecurity;
2. safety;
3. reliability;
4. intellectual-property protection;
5. regulatory obligations;
6. fraud prevention;
7. prevention of counterfeit components;
8. technical incompatibility;
9. genuine innovation;
10. protection of consumers from defective repairs.

The critical question is whether the restriction is necessary and proportionate to the legitimate objective, particularly where less restrictive competitive alternatives exist.

27. Enforcement and Remedy Options

Where unlawful conduct is established, possible remedies may include:

Access remedies

Require access to:

• spare parts;
• diagnostic tools;
• technical information;
• APIs;
• firmware.

Interoperability remedies

Require compatibility with competing components.

Non-discrimination

Require equal access for independent repair providers.

Contractual remedies

Remove restrictive warranty or licensing provisions.

Behavioural remedies

Prohibit discriminatory treatment of independent service providers.

Structural remedies

In exceptional cases, competition authorities may consider structural intervention where behavioural measures are inadequate.

28. Practical Analytical Framework

A useful exam framework is:

DEVICE LIFECYCLE CONTROL

1. Identify the device

↓

2. Map its lifecycle

Design → Sale → Update → Repair → Upgrade → End-of-life

↓

7. Measure competitive effects

Price / choice / innovation / entry / repair

↓

8. Examine objective justification

Safety / security / innovation / regulation

↓

9. Consider less restrictive alternatives

↓

10. Determine appropriate remedy

29. Key Legal Principles Emerging From the Cases

The cases collectively support several important propositions:

1. A competitive primary market does not necessarily prevent aftermarket power — Kodak. 
2. Brand-specific spare-parts and repair markets can be independently relevant — Shamsher Kataria. 
3. Technology platforms can be leveraged into adjacent markets — Microsoft. 
4. Technological compatibility mechanisms can influence aftermarket competition — Static Control/Lexmark. 
5. Access to spare parts can be important for independent maintenance competition — U.S. v. IBM. 
6. Software support can become an important part of a technological product's lifecycle — Oracle v. HPE. 
7. Software updates can materially affect the useful life and performance of physical devices — Apple/CMA. 
8. Modern device ecosystems create competition issues extending across hardware, software and interoperability — the U.S. Apple litigation illustrates this developing area, although the allegations remain contested and are not equivalent to a final liability finding. 

30. Conclusion

Device lifecycle control strategies encompass much more than deciding when to launch or discontinue a product. In digital and connected-device markets, lifecycle control can determine who controls the parts, repair services, software, firmware, APIs, accessories, upgrades and ultimately the replacement decision.

The most important competition-law insight is the aftermarket problem. Eastman Kodak established that competition in the original equipment market does not necessarily eliminate market power over a brand-specific aftermarket. Indian jurisprudence, particularly Shamsher Kataria, similarly demonstrates the significance of spare parts, diagnostic tools and repair information.

The Microsoft and Lexmark cases additionally demonstrate how technological integration and compatibility mechanisms can affect neighbouring markets. The IBM litigation illustrates the importance of continued access to parts and maintenance, while the Apple and Oracle matters show how software support and interoperability increasingly determine the practical lifespan of physical devices.

Accordingly, lifecycle control becomes a serious competition-law issue where a firm with substantial market power uses parts restrictions, software restrictions, authentication, incompatibility, repair-information control, or end-of-life policies not merely to improve the product but to foreclose competing aftermarket providers or reinforce its existing market position. The legality of a particular strategy ultimately depends on the relevant market, market power, exclusionary effects, consumer impact, objective justification and applicable competition-law framework.
