When it comes to intellectual property (IP) rights, many business owners assume that any overlap between brand names will lead to legal trouble. However, that’s not always the case. Under the right circumstances, two businesses can legally coexist—even if their names are similar. Understanding when IP infringement occurs is crucial, but just because two things look or sound alike doesn’t always mean legal action is warranted.

A Real-World Example: The “Super Mario” Case

A great example of IP coexistence is the recent story of a supermarket owner in Costa Rica named Mario, who chose to name his store “Super Mario.” At first glance, you might assume this would be an easy lawsuit for Nintendo, a global gaming giant. However, when the company took legal action, the courts ruled in Mario’s favor, demonstrating that trademark rights have limitations and that businesses in different industries can sometimes share a name.

So, when can two brands legally share a name? Here are three key factors to consider:

1. Market Segments Matter

One of the biggest factors in trademark disputes is whether the businesses compete in the same industry. In the case of Mario’s supermarket and Nintendo’s video games, there was no direct competition. Groceries and digital entertainment are completely different markets, meaning customers aren’t likely to confuse the two brands.

2. Avoiding Customer Confusion

If a name or brand is likely to mislead consumers into thinking one business is connected to another, that’s a legal issue. However, if two companies operate in separate industries and have distinct branding, they’re less likely to cause confusion. Think about Nintendo’s bright, animated visuals versus a supermarket’s simple, practical design—there’s little chance that shoppers will mix them up.

3. Fair Use & Parody

Parody is another critical legal consideration. If a brand name is used to comment on, critique, or satirize an existing one without competing directly, it may be legally protected. Many well-known parodies reference famous brands, movies, or songs for humor without violating intellectual property laws. However, businesses must understand the legal limits of parody to avoid unintended legal consequences.

The Takeaway: How to Protect Your Brand

Even massive companies like Nintendo cannot automatically claim exclusive rights to every instance of a name. If you’re looking to trademark a brand name, consider these key steps:

• Check for market overlap using the USPTO trademark database.
• Assess the likelihood of customer confusion.
• Ensure your branding is distinct and recognizable.
• Understand the role of parody and fair use in IP law.
