The Expiration of LEGO's Patent and the Truth Behind the Lawsuits

The Expiration of LEGO's Patent and the Truth Behind the Lawsuits

Did you know about the legal battles hidden behind the perfect interlocking system of LEGO blocks that we all played with as kids?


The Expiration of LEGO's Patent and the Truth Behind the Lawsuits

Hello! While assembling LEGO with my nephew recently, I got curious. Why are there so many identical knockoff blocks despite LEGO's unique interlocking system? Upon investigating, I found that LEGO's patent had already expired, leading to countless legal disputes. One of the most famous cases was the lawsuit with Canada's Mega Bloks. Today, let's explore the aftermath of LEGO's patent expiration and how the company fought to protect its kingdom.

History and Expiration of LEGO's Patent

LEGO's unique interlocking system received legal protection when its patent was filed in 1958. This design offered technical precision beyond a mere toy, gaining immense popularity not only with children but also with adult fans. However, like all patents, the 20-year protection period eventually expired. LEGO's key connection patent expired in 1978, and shortly after, similar products began to emerge in the market. From that point onward, LEGO had to adopt other legal strategies to maintain its exclusive market position.

Rise of Copycat Block Brands

Brand Name Country of Launch Features
Mega Bloks Canada Compatible structure with LEGO, emphasizes price competitiveness
Octo Bricks China Products based on animated IPs
Sluban Netherlands Focused marketing in European markets

After the patent expiration, the strongest competitor to LEGO was Mega Bloks from Canada. The company quickly dominated the North American market by releasing blocks that interlocked in almost the same way as LEGO. In response, LEGO filed a lawsuit for trademark and design infringement. However, the results were not favorable for LEGO. The Canadian Federal Court dismissed LEGO's claims for the following reasons:

  • The block’s interlocking structure is considered a 'functional element' and is not protected.
  • Trademark rights should focus on 'source identification' rather than functionality.
  • Merely similar appearance does not constitute trademark infringement.

The Border Between Design Protection and Functionality

The biggest legal barrier LEGO faced was the 'distinction between functionality and design.' In intellectual property law, functional elements are protected only by patents, and once a patent expires, anyone can use the technology. Therefore, parts essential to the product's performance, such as the interlocking structure of the blocks, cannot be protected by trademarks or design registration. LEGO attempted to argue that the appearance of the blocks was central to the brand's identity, but courts in several countries rejected this claim.

International Verdicts and LEGO’s Strategy

Country Verdict LEGO’s Strategy Change
Canada Refusal of trademark rights Strengthened brand story
European Union Invalidated 3D trademark registration Shifted focus to marketing outside of intellectual property
USA Denied exclusive protection Expanded licensing strategy

New Solutions for Protecting Brand Value

Facing the limits of patent protection, LEGO employed various strategies to protect its brand value. Particularly, brand marketing based on creativity and emotion, media expansion, and IP collaborations played a crucial role in transforming LEGO from a simple block brand to a global content brand. Below are some of the key strategies LEGO adopted.

  • Content IP expansion such as ‘The LEGO Movie’ series
  • Development of various theme kits and expansion of adult lines
  • Strengthening CSR campaigns emphasizing brand philosophy

Frequently Asked Questions

Q When exactly did LEGO's patent expire?

LEGO's connection technology patent was filed in 1958 and expired in 1978.

Q Does patent expiration mean all products can be copied?

Functional elements can be copied, but trademark and design elements can still be protected.

Q Is Mega Bloks still competing with LEGO?

Yes, Mega Bloks still sells similar blocks to LEGO and shares the market.

Q How did LEGO try to protect itself legally afterward?

LEGO tried to register 3D trademarks and protect its design, but most of these efforts were rejected.

Q What is LEGO's key strategy to differentiate from knockoffs?

LEGO differentiates itself through brand emotions, content IP expansion, and premium product lines.

Q What should consumers be aware of?

Although knockoff products are cheaper, their quality and safety can vary greatly, so it's essential to compare carefully before purchasing.

In Conclusion

It’s fascinating to think about the deep legal drama hidden behind a LEGO block! The expiration of the patent didn't mark the end of the story, and the battle to protect the brand continued. Ultimately, LEGO shifted its focus to winning over consumers' hearts rather than in the courtroom. Now, when assembling a LEGO set, we can also think about the creativity and fierce survival strategies that went into its design. What do you think? Was LEGO’s response successful?

The Trademark Dispute Over Nestlé KitKat's Shape

The Trademark Dispute Over Nestlé KitKat's Shape

Curious about why the shape of a chocolate bar triggered years of international legal battles?


The Trademark Dispute Over Nestlé KitKat's Shape

Hello, everyone. I really love chocolate, and Nestlé KitKat has been on my snack list since I was a child. But I was recently shocked to find out that this familiar chocolate was at the center of a fierce legal battle in court. It wasn’t just about taste or branding—it was the ‘shape’ itself that became the core of a trademark dispute. Today, I want to share this surprising story with you.

The Origin of the Dispute: Nestlé vs Cadbury

This whole dispute began when Nestlé attempted to register the ‘four-finger’ shape of its chocolate bar as a trademark in Europe. Competitor Cadbury strongly opposed this registration, arguing that the shape was not original but simply a functional design. Nestlé countered, stating that its KitKat was so strongly recognized by consumers that its shape had become a means of identifying the brand. The two giant chocolate companies clashed for years over whether a simple shape could actually be considered a trademark.

Country Ruling Key Reasoning
UK Registration Refused Lack of evidence of consumer recognition
EU Final Rejection Insufficient recognition across all member states
Germany Partial Acceptance Recognition in specific regions

Can ‘Shape’ Be a Trademark?

Shape trademarks aim to protect the physical appearance of products, not just logos or text. However, this is one of the most difficult areas of trademark law because functional designs are not eligible for protection. For a shape to be recognized as a trademark, consumers must be able to associate it with the brand.

  1. The shape must be distinctive
  2. It should focus on visual recognition, not functional aspects
  3. Clear evidence from consumer surveys is required
  4. It must be distinguishable from similar products

The Legal Impact of Consumer Perception

The key issue in this dispute was whether consumers could associate the shape with the brand. The court ruled that consumer recognition must go beyond mere familiarity and function as a trademark. The European Court of Justice stated that “there must be a uniform recognition across all member states,” a very high bar to meet. Despite Nestlé submitting data from the UK, France, and Germany, it was insufficient to meet the EU-wide requirement, resulting in the rejection of the trademark registration.

Meaning of the Verdict and Global Reactions

Area Summary of Reactions
Intellectual Property Experts A new benchmark for trademark protection scope
Brand Marketers Reconsideration of strategies emphasizing visual differentiation of brands
Competitors Expectations for increased freedom in product design

Lessons for Brand Protection Strategy

This case is not just about a chocolate brand but delivers an important message to all businesses. It shows how difficult it is to protect the shape of a product as a trademark and how strict the requirements are. For companies aiming to protect their brand through design, the following strategies might be necessary:

  • Build identity beyond simple visual elements
  • Clarify design elements that differentiate from functional ones
  • Continuously collect consumer recognition data and evidence
  • Consider strategies centered around symbols and naming rather than just product shape protection

Frequently Asked Questions

Q Has the KitKat shape ever been trademarked?

It has been registered in some countries, but it was ultimately rejected under EU law.

Q What are the conditions for a shape to be a trademark?

The shape must not be functional and must be recognized by consumers as representing the brand.

Q Why did Cadbury oppose this trademark registration?

They opposed it because they believed the shape was too generic and functional, aiming to prevent Nestlé from monopolizing it.

Q What is the message this verdict sends to companies?

It highlights the difficulty of protecting a product shape as a trademark and underscores the importance of securing consumer recognition data.

Q How should companies prepare for similar disputes in the future?

They should collect consumer survey data and prove the brand’s association with the shape, while distinguishing functional elements from visual design features.

Q What strategy did Nestlé adopt after the case?

Nestlé returned to branding strategies focused on advertising and packaging, emphasizing brand names rather than product shapes.

In Conclusion

The trademark dispute over the KitKat shape was fascinating, wasn’t it? It’s not just about a delicious and familiar chocolate, but also about brand protection, legal boundaries, and consumer perception. It makes you think about how many ‘shapes’ we recognize as brands in our daily lives. What product shape comes to your mind first? Share your thoughts in the comments, and let’s explore the intriguing connection between brands and consumers!

Screen Golf Patent Wars: Innovation or Monopoly?

Screen Golf Patent Wars: Innovation or Monopoly?

A sensor worth millions? Let's uncover the hidden truth behind the patent disputes in the screen golf market.


Screen Golf Patent Wars: Innovation or Monopoly?

Hello! Many of you probably enjoy screen golf on the weekends, right? I also go with friends often, and every time I see the trajectory of the ball displayed so accurately, I’m amazed. But did you know that these technologies are surrounded by dozens of patents? In recent years, fierce patent lawsuits have been ongoing between companies regarding screen golf technology. Today, I’ll summarize the technologies in dispute, and how these legal battles are affecting consumers and the industry!

What is Screen Golf Patent?

Screen golf may seem like just a game, but it involves dozens of sophisticated technologies. From sensor technologies that detect the ball's speed, direction, and spin, to simulation engines that render the 3D terrain of actual golf courses, and even the screen's response speed during a shot, it is a complex technology that combines both software and hardware. To protect and exclusively use these technologies, companies register patents and use them as a basis to restrict other companies' use of the technology or demand royalties. As a result, patents have become the 'invisible battlefield' of the screen golf industry.

Major Patent Disputes Between Companies

Disputing Companies Key Issues Result
Golfzon vs. SG Golf Unauthorized use of sensor and simulation algorithms Some patents invalid, others prohibited
Golfzon vs. Other SMEs Sensor installation position and UI similarity Some settled, others ongoing litigation
Company T vs. Overseas Company B Conflict over VR-based 360-degree projection technology International arbitration ongoing

Key Technologies in Dispute

The technologies that repeatedly appear in screen golf patent disputes include the following. Most of them are directly related to accuracy, immersion, and operability.

  • 2D or 3D sensor-based ball trajectory analysis algorithms
  • Club-specific ballistic prediction simulation logic
  • Screen feedback speed and collision reaction implementation
  • User interface (UI) and menu layout
  • Golf course terrain data implementation and rendering engine

The court in screen golf patent disputes primarily considers “technical progress” and “differentiation from prior art” when making judgments. For example, mere similarity in sensor installation positions or UI is not enough for infringement, and substantial functional differences must be demonstrated. Additionally, systems that react automatically without user input are often judged based on 'implementation difficulty' and 'commercial impact'.

  • Golfzon vs. SG Golf ruling: ‘Trigger signal transmission method’ patent is valid
  • Small company UI similarity lawsuit: "No functional similarity" ruled no infringement
  • Overseas company imitation lawsuit: Overseas patent scope too narrow, lost case

Impact on Market and Consumers

Impact Factor Explanation
Increased Consumer Prices Increased royalty fees could lead to higher usage fees
Market Monopoly Intensification Concerns over entrenched market structure dominated by large companies
Stifling Technological Innovation Dampened competition makes it harder for new technologies to enter
Limitations on Service Diversity Limitations on UI and sensor utilization hinder differentiation

Future Direction of Technology Competition

  • AI-based shot analysis and automatic coaching technology rise
  • Expansion of XR (extended reality) integrated screen golf platforms
  • Expansion of overseas patent filings and intensified global competition
  • Promotion of fair competition through open-source-based platform development

Frequently Asked Questions (FAQ)

Q What does the screen golf patent cover?

It includes hardware and software aspects, such as sensor technology, simulation algorithms, user interface, and screen implementation methods.

Q Does the patent dispute directly affect consumers?

Yes. Increased royalties or legal costs can lead to higher fees or service restrictions.

Q Can new technologies be patented by competitors?

If the new technology is similar to existing patents, it can be considered infringement, so differentiated approaches are necessary.

Q Does patent registration guarantee victory in lawsuits?

No. Even registered patents can be invalidated if technical advancement or effectiveness is proven insufficient.

Q Can patent issues be resolved without a lawsuit?

Yes. License agreements or joint technology development partnerships can resolve disputes without litigation.

Q Can screen golf technology be protected overseas?

Yes, through international patent filings, but each country has its own review criteria, so a separate strategy is necessary.

In Conclusion

Screen golf is not just a leisure activity, but an industry combining cutting-edge technology, and a battleground for intellectual property rights. Personally, I thought, "How could there be so many patents for just hitting a ball?" But after investigating, I realized just how delicate and sophisticated each technology is. Even as we enjoy playing golf on the screen, these invisible patent disputes are still ongoing. I hope that through fair competition, not monopolies, we can create a better user experience and foster a market where more companies can freely compete. Like on the golf course, "fair play" is the most beautiful approach to technology!

Mutant Mouse Patent Dispute – The Border Between Biotechnology and Intellectual Property

Mutant Mouse Patent Dispute – The Border Between Biotechnology and Intellectual Property

Could a single mouse ignite an international patent war? A tense tug-of-war between science and law over life.


Mutant Mouse Patent Dispute – The Border Between Biotechnology and Intellectual Property


Hello! Today’s case may be unfamiliar, but it shook both the biotechnology and legal communities — the Mutant Mouse Patent Dispute. This genetically engineered mouse, developed for disease research, has been widely used in laboratories around the world. But a fierce battle over the 'ownership' of this mouse has arisen among universities, governments, and corporations. This case goes beyond experimental animals and poses the philosophical question: Can living organisms be patented? Let’s dive into this fascinating and important story.

1. What is OncoMouse?

OncoMouse is a genetically modified laboratory mouse developed by a research team at Harvard University. This mouse was designed by inserting specific genes so that cancer develops naturally, making it extremely useful in cancer research. It became the standard model in the biomedical field worldwide, especially in studies related to breast and skin cancers.

However, controversy arose over whether this mouse could be considered a “patentable subject”. The question was whether a genetically altered organism could be legally recognized as intellectual property.

2. Patent Filing and Harvard's Ownership Claim

In 1984, Harvard University filed the first patent application for a living organism with the United States Patent and Trademark Office (USPTO). In 1988, the USPTO approved the patent, stating that “living organisms artificially created through genetic modification can be patented.” This marked the first animal patent in U.S. history and caused a major stir.

Item Details
Patent Name Transgenic non-human mammal (OncoMouse)
Applicant Harvard University (Inventor: Philip Leder)
Patent Granted Year 1988 (U.S.), 1992 (some European countries)
Controversy Ownership of living organisms, expanded ethical debates

3. Disputes Over Patent Recognition in Different Countries

While the OncoMouse patent was filed in many countries after the U.S., each nation produced different outcomes. Some recognized the patent, while others rejected or limited it for ethical reasons.

  • United States: First approval, sparked biotechnology industry growth
  • Canada: Recognized DNA manipulation, but not patenting the animal itself
  • European Patent Office (EPO): Approved with limitation to “mouse” after ethical debates (1992)
  • Germany, Netherlands: Rejected or conditionally approved based on animal welfare laws

These international differences reflect the philosophical variations in how legal status is granted to living organisms and in perceptions of scientific technology.

The OncoMouse patent raised a fundamental question beyond intellectual property: Can humans “own” or “commercialize” life? Granting a patent on an entire living being—not just a part—has been criticized from the perspective of animal rights and bioethics.

Animal rights groups and ethicists continuously questioned whether it is truly justifiable for genetically modified animals to suffer and be sacrificed. In some countries, there were even discussions of legislation to ban life patents altogether.

5. The Dilemma Between Scientific Research and Commercialization

After the OncoMouse patent, disputes emerged between universities/research institutions and biotech companies over profit sharing and access limitations. Harvard licensed the patent to DuPont for commercialization, and as a result, researchers had to pay usage fees to use the mouse.

Field Impact
Public Research Concerns over restricted research due to licensing fees
Commercialization Provided exclusive profit opportunities to patent holders
International Cooperation Sparked conflicts between nations due to differences in patent coverage

6. What is the Future of Biotechnology Patents?

With the emergence of CRISPR, patents for gene-edited life forms are expected to become even more complex and crucial. As patent scopes expand to include AI-designed organisms, synthetic life forms, and genetic data databases, balancing law and ethics has become more important than ever.

  • Could synthetic biology also become subject to patents?
  • Rising issues over ownership of genetic data
  • Growing need for mechanisms ensuring global public research access

Ultimately, we face the question: “Who defines life, and who is entitled to own it?”

Frequently Asked Questions (FAQ)

Q What diseases is OncoMouse used to study?

It is primarily used in research on various types of cancer, including breast cancer, skin cancer, and colon cancer. It is a highly useful model for studying tumor development and treatment mechanisms.

Q Can living organisms be patented?

In some countries, yes—but not all. Patents are generally granted only when there is a clear artificial intervention, such as genetic modification.

Q Who is allowed to purchase OncoMouse?

DuPont, which held the license from Harvard, sold it to research institutions, universities, and pharmaceutical companies. Commercial use required a separate licensing agreement.

Q Why did some countries reject the patent?

Mainly due to ethical reasons. Many countries considered human ownership over living beings unjust or found it incompatible with animal welfare laws.

Q Do patents hinder research?

They can. Public research institutions and nonprofits have raised concerns that legal and financial barriers make access to such technologies difficult.

Q Will patents on living organisms continue to increase?

The potential is high with advancements in gene-editing technologies, but sustainable systems will require more refined legal and ethical standards.

Reconsidering the Boundaries of Rights and Ownership Over Life

The OncoMouse patent dispute isn’t merely a clash between science and intellectual property—it fundamentally asks how we define and regard life. Should life be viewed solely as a tool, or should it be treated with respect? As genetic technologies evolve, this debate will intensify. I hope today’s story inspires reflection on the future of biotechnology. Where do your thoughts lie?

NFT Art Copyright Disputes – The Clash Between Digital Art and the Law

NFT Art Copyright Disputes – The Clash Between Digital Art and the Law

Are NFTs the future of digital assets or a hotbed of copyright disputes? A heated debate is unfolding, confusing both creators and buyers alike.


NFT Art Copyright Disputes – The Clash Between Digital Art and the Law

Hello! I'm someone with a deep interest in digital content and law, and one of the hottest issues I've been following lately is the copyright disputes in NFT art. Artists who mint their own artwork as NFTs end up being sued, while third parties turn famous pieces into NFTs without consent. These situations severely impact both the protection of creator rights and the credibility of the NFT market. Today, I’d like to walk you through some major cases of NFT copyright disputes and explore what direction digital copyright should take in this new era.

1. What is NFT Art?

NFT art refers to digital artworks assigned a unique ‘token’ through blockchain technology. This token acts as a non-fungible digital certificate, used to verify the ‘ownership’ of a specific image, video, or 3D file.

However, this ownership is distinctly different from copyright. NFT buyers can trade the token, but do not automatically receive the rights to modify the original work or use it commercially. This distinction lies at the heart of many copyright disputes.

2. The MetaBirkins Case: Clash with a Luxury Brand

One of the most well-known cases of NFT copyright dispute is the “MetaBirkins” incident. Digital artist Mason Rothschild released an NFT series parodying Hermès’ iconic “Birkin” bags. In response, Hermès filed a trademark infringement lawsuit.

Item Details
Artwork Name MetaBirkins (NFT series)
Complainant Hermès
Core Issue Trademark infringement, brand confusion, freedom of art vs. commercial use
2023 Ruling Hermès won, awarded approximately $130,000 in damages

This ruling set a key precedent that even if NFT artworks are considered artistic expression, they can still face legal consequences for trademark infringement.

3. Unauthorized Minting: NFTs Issued Without the Creator’s Consent

On NFT platforms, it is common for third parties to illegally mint someone else’s artwork, photos, or music and sell them. In fact, OpenSea revealed that about 80% of transactions in 2021–2022 involved plagiarized content.

  • Minting screenshots of Twitter or Instagram images without the artist’s permission
  • Even AI-generated images are being turned into NFTs, further confusing creators
  • Even if a takedown is requested, tracking already-traded NFTs is nearly impossible

Because NFTs are immutable, recovering from copyright infringement becomes incredibly difficult. This is a prime example of the current gap between technology and legal systems.

4. The Legal Void in Current Copyright Law

NFT technology is evolving rapidly, but current copyright laws do not adequately reflect the digital asset and blockchain environment. Specifically, there is a lack of legal standards regarding the scope of rights between NFT issuers and original creators, platform responsibilities, and automated minting systems.

As a result, NFTs can be easily altered and traded as illegal copies, and even when victims raise objections, it’s difficult to achieve actual deletion or compensation under the current system.

5. Efforts to Protect Creator Rights

In response, various global efforts are being made to protect creators. NFT platforms are beginning to implement copyright verification systems and shift toward creator-centric contract structures.

Protection Effort Description
Original Verification Before NFT Minting Pre-verification through creator account authentication and original image hash matching
Copyright Holder Rewards Automatically pays a percentage of secondary NFT sales to the original creator
Illegal Mint Detection Solutions AI-based image similarity detection and automatic takedown request functionality

As the NFT market becomes increasingly global, governments and international organizations are beginning to revise copyright norms. In the near future, blockchain-based copyright registration systems, smart contract-based licensing frameworks, and standardized dispute resolution systems across platforms are likely to emerge.

  • WIPO (World Intellectual Property Organization) has initiated discussions on international NFT copyright agreements
  • EU: Strengthening platform accountability via the Digital Services Act (DSA)
  • Countries like South Korea, the U.S., and Japan are conducting blockchain copyright pilot projects
  • Community-driven “NFT Copyright Certification DAOs” are also emerging

Frequently Asked Questions (FAQ)

QDo you own the copyright when you buy an NFT?

No. Purchasing an NFT gives you digital ownership, but copyright typically remains with the original creator. Commercial use requires a separate license agreement.

QWhy did the court rule in favor of Hermès in the MetaBirkins case?

Because even if the NFT is art, it cannot legally infringe on trademarks or cause consumer confusion.

QCan anyone mint NFTs?

Technically, yes. But if you mint someone else's work without permission, you could face copyright infringement liability.

QCan stolen NFTs be deleted?

Platforms can delete listings, but the blockchain record remains permanent. So practical removal is difficult.

QWhat are NFT platforms doing to protect copyrights?

Some platforms are adopting creator authentication before minting, AI-based detection for illegal minting, and creator royalty systems, though standards are not yet unified.

QWill NFT copyright disputes increase or decrease?

They are likely to increase in the short term, as laws and systems lag behind rapid technological growth. But with global standards, stability may improve over time.

The Limits of Freedom and Rights in Digital Creation: How Far Can NFTs Go?

NFTs are an innovation that has opened new doors in the digital art market, but they also expose blind spots in law and policy. The current structure—where copyright and ownership are traded without clear distinction—can be risky for both creators and buyers. As we chase the pace of technological innovation, we must also consider the ethics and legal frameworks that support it. I hope this post helped broaden your perspective on the intersection of art and law in the NFT era.
