Justice moves slowly, but it eventually arrives. After a marathon 15-year legal battle, Nintendo has emerged victorious in a patent infringement lawsuit against third-party accessory maker BigBen Interactive (now Nacon) over unauthorized Wii controller technology. The October 30, 2025 ruling awarded Nintendo just under €7 million ($8.2 million USD) in damages—but the saga might not be over yet.
What Was the Wii Controller Lawsuit About?
The legal battle began back in June 2010 when Nintendo filed suit in Germany against BigBen Interactive, alleging the company’s third-party Wii controllers violated a European patent covering critical Wii Remote technology.
What Nintendo’s Patent Covered:
- Ergonomic design elements specific to the Wii Remote
- Sensor technologies integral to the Wii controller ecosystem
- Core functionality that defined how the Wii Remote operated
Nintendo’s argument was straightforward: BigBen used patented technology without permission, essentially stealing profits that should have gone to official Nintendo hardware sales.
BigBen’s Defense Strategy (That Didn’t Work)
BigBen Interactive tried a creative defense strategy that ultimately failed:
Their argument: Even if consumers didn’t buy BigBen controllers, they would have purchased from other third-party manufacturers instead—not from Nintendo. Therefore, Nintendo didn’t actually lose those specific sales.
Why this mattered: This defense aimed to reduce the damages Nintendo could claim by arguing the company wouldn’t have captured those sales anyway.
The court’s response: Rejected. The Mannheim Regional Court dismissed this reasoning entirely.
The Court’s Decision: $8.2 Million in Damages
On October 30, 2025, the Mannheim Regional Court delivered its final ruling after 15 years:

Damages Breakdown:
- Total award: Just under €7 million ($8.2 million USD)
- Accrued interest: Nearly €3 million (accumulated since 2018)
- Legal costs: Included in the total
How Damages Were Calculated:
The court used a lost-profits theory, which assumed Nintendo would have captured all of BigBen’s controller sales if the infringement hadn’t occurred.
According to Nintendo’s German legal team at Bardehle Pagenberg:
“Hypothetical mitigating circumstances that would have amounted to third-party activities that also trigger damages could not be taken into account in favor of the infringer.”
Translation: The court wouldn’t entertain the “they would’ve bought from someone else anyway” defense.
Timeline of the 15-Year Legal Battle
This wasn’t Nintendo’s first win in this case:
- June 2010: Nintendo files lawsuit in Germany
- July 2011: Initial ruling finds BigBen guilty of infringement
- 2011-2025: Multiple appeals uphold infringement findings
- October 30, 2025: Final damages award of $8.2 million
Important: BigBen (now Nacon) has already begun pursuing an appeal, meaning this might not be the final chapter after all.
Nintendo’s Reputation for Protecting IP
This 15-year victory is just one example of Nintendo’s aggressive approach to intellectual property protection. The company has built a reputation as one of gaming’s most litigious defenders of patents and trademarks.
Recent High-Profile Nintendo Lawsuits:
1. Palworld (Pocketpair) – September 2024
Nintendo and The Pokemon Company filed a patent infringement lawsuit against Palworld developer Pocketpair, claiming the game’s mechanics copied Pokemon systems:
- Summoning creatures
- Throwable capture spheres (similar to Poke Balls)
- Creature riding and traversal mechanics
Nintendo’s demands:
- Injunction forcing changes to Palworld’s mechanics
- Approximately $65,000 USD in damages
Pocketpair’s response:
- Claims systems are original or existed in other games first
- Made iterative changes including adjusting gliding mechanics
- Temporarily removed ability to summon Pals by throwing spheres
Plot twist: In October 2025, Japan’s Patent Office rejected one of Nintendo’s patents, with examiners citing similar systems in other games and stating Nintendo’s claimed inventions weren’t sufficiently novel.
2. Moddedhardware.com – September 2025
Nintendo won a patent infringement case in Washington state against Ryan Daly, operator of moddedhardware.com (now defunct).
The allegations:
- Knowingly sold devices circumventing Switch DRM
- Copied and sold pirated Nintendo games
The outcome: After Daly represented himself in court, he agreed to a $2 million USD settlement.
Why This Wii Lawsuit Took 15 Years
Patent litigation, especially international cases, typically involves:
- Multiple appeals: Each side can challenge rulings repeatedly
- Complex technical arguments: Courts must understand sophisticated technology
- Damages calculations: Determining lost profits requires extensive analysis
- International jurisdiction: Cross-border cases add complexity
The fact that initial 2011 rulings found BigBen guilty, yet the case continued for 14 more years, demonstrates how thoroughly defendants can contest patent claims.
What This Means for Third-Party Accessory Makers
This ruling sends a clear message to companies producing gaming accessories:
Key takeaways:
- Patents are enforceable even years after infringement
- “They would’ve bought elsewhere” isn’t a valid defense
- Lost-profit damages can be substantial, especially with accumulated interest
- Nintendo will pursue cases for over a decade if necessary
Third-party manufacturers must either:
- License technology properly from console makers
- Ensure their designs don’t infringe existing patents
- Accept the legal and financial risks of potential litigation
Could BigBen Still Win on Appeal?
While Nintendo has won this round, BigBen (Nacon) has already begun appealing. Possible appeal arguments might include:
- Challenging the lost-profits calculation methodology
- Questioning the patent’s validity or scope
- Arguing the damages amount is excessive
- Presenting new evidence about third-party market dynamics
However, given that multiple courts have already upheld the infringement findings over 15 years, overturning this decision seems unlikely.
The Broader Context: Nintendo’s IP Strategy
Nintendo’s willingness to pursue this case for 15 years reflects its broader corporate philosophy:
Why Nintendo is so aggressive:
- Brand protection: Counterfeit or infringing products damage brand integrity
- Revenue protection: Third-party accessories cut into official hardware sales
- Deterrence: Lengthy, expensive lawsuits discourage future infringement
- Precedent-setting: Wins establish legal foundations for future cases
This approach has made Nintendo one of the most protective companies in gaming—for better or worse, depending on your perspective.

Bottom line: Nintendo’s 15-year legal victory over BigBen Interactive proves the company’s commitment to protecting its intellectual property, no matter how long it takes. The $8.2 million award—including years of accumulated interest—serves as a costly lesson for third-party manufacturers: infringing on Nintendo’s patents comes with serious, long-lasting consequences. While BigBen may appeal, the multiple court rulings over a decade and a half suggest this victory will likely stand.
