Intellectual Property Moat: How Patents, Copyrights, and Trade Secrets Protect Profits
We’ve now covered four of the five economic moats:
Today, we’re finishing the series with the final moat: the intellectual property moat.
Quick note: Most great businesses don’t rely on just one moat. Many of the companies below have several. But today we’re focusing on just one weapon in their arsenal — legally protected ideas.
WHAT IS AN INTELLECTUAL PROPERTY MOAT?
An intellectual property moat is a competitive advantage created by legal ownership of an idea.
If a company invents something valuable — a drug, a character, a technology, or even a recipe — the law can prevent competitors from copying it.
In other words: “This idea is mine. Use it, and my lawyers will say hello.”
When people talk about investing in a company because it developed a new drug or technology that everybody wants, they are talking about intellectual property.
For investors, an intellectual property moat can protect profits for years because competitors are legally blocked from copying the product.
4 TYPES OF INTELLECTUAL PROPERTY MOAT
If a company can legally prevent others from copying its idea, it may be able to create an intellectual property moat.
You can think of intellectual property as four different ways to say, “This is mine.”
PATENTS (“HOW IT WORKS” OWNERSHIP): NOVO NORDISK
You may know someone who has used Ozempic to treat their type-2 diabetes and lose weight. Novo Nordisk owns the patent for Ozempic. This blocks competitors from using Novo Nordisk’s formula for a set number of years.
Other companies can still create their own weight-loss drug; they just can’t use the same formula. Hence, Mounjaro, another diabetes medication that is produced by the pharmaceutical company Eli Lilly, uses a different formula.
COPYRIGHTS (“CREATIVE WORK” OWNERSHIP): WARNER BROS. DISCOVERY
If you’ve been keeping up with the news, Paramount Skydance and Netflix were recently in a bidding war to acquire Warner Bros. Discovery.
Why?
Warner Bros. Discovery owns the rights to massive entertainment franchises like Harry Potter, Game of Thrones, and the characters of DC Entertainment.
Because it owns the copyrights to these stories and characters, other studios can’t legally recreate them. They can only license the rights—which is why streaming platforms often pay enormous sums just to host them.
TRADEMARKS & TRADE DRESS (“BRAND IDENTITY” OWNERSHIP): DISNEY
Disney created some of the most beloved cartoon characters that it protects fiercely. Nobody would want to buy a T-shirt with a picture of a common sewer rat, but if it looks like Mickey Mouse, it’ll sell like hotcakes.
If you tried to screenprint your own T-shirts with Mickey Mouse on them, you could land in Disney’s legal crosshairs because they own the trademarks to the design.
TRADE SECRETS (“SECRET FORMULA” OWNERSHIP): COCA-COLA
Being a one-trick pony isn’t always bad if your trick is world-class.
The Coca‑Cola Company isn’t literally a one-product business, but its crown jewel is the 140-year-old secret formula behind Coca-Cola.
In the mid-80s, Coca-Cola tried to replace the formula with New Coke. The backlash was so bad that Coca-Cola brought back its original formula just a few months later, rebranding it as Coca-Cola Classic.
Today the recipe is still one of the most famous trade secrets in the world — supposedly locked in a vault and known by only a handful of people.
HOW INTELLECTUAL PROPERTY MOATS CAN WEAKEN
Patents, copyrights, and trademarks offer strong protection, but they’re not invulnerable moats.
EXPIRING PROTECTIONS
Walk into any drug store, and you’ll see generic medication sold right next to the name brands. In fact, savvy shoppers know they can save a lot of money by buying generics. Same drug formula, but cheaper.
So what happened to patent protection?
You might be surprised to learn that drug patents are relatively short. Drug patents typically last 20 years from the date they’re filed, but much of that time is eaten up by clinical trials and regulatory approval. By the time the drug actually hits the market, companies often have closer to 7–12 years of real exclusivity left.
Once the patent expires, other companies can copy the formula, driving prices down. Great for consumers like you and me, but there goes that moat unless the company has other drugs in development.
Similarly, copyrights and trademarks can also expire, although their shelf life is much longer. Have you noticed the slate of horror movies based on Disney characters that started coming out in the past few years? There was Winnie-the-Pooh: Blood and Honey, The Mouse Trap, and Screamboat, just to name a few.
DUPLICATE CULTURE AND KNOCKOFFS
If you were a teen or older in the early 2000s, UGG boots immediately conjure a specific picture in your mind. I remember so many women in my workplace walking around like they just stepped out of their igloos.
UGG boots are so recognizable, you’d think their design would be protected from dupes. UGG’s parent company, Deckers, thought so too.
But it recently saw its moat weaken when it unsuccessfully sued retailer Quince for selling similar-looking shoes.
In 2025, a federal court ruled that key design elements — like ankle-high suede boots with sheepskin lining — were common in the footwear industry, meaning they couldn’t be protected as unique trade dress.
Unfortunately for many companies, consumers love a good dupe. Social media is filled with influencers bragging about the cheaper version they found at Costco or Trader Joe's that looks almost identical to the expensive one.
Usually, there’s no infringement of patents or trade dress going on, but the celebration of dupe culture encourages knock-off industries. China, for example, is infamous for creating knock-off products of famous American brands.
Too bad copyrights, patents, and trademarks aren’t global by default. A U.S. trademark, for example, typically only provides protection within the U.S. That, combined with differences in culture and law enforcement in other countries, makes dupe culture difficult to control.
TECHNOLOGICAL DISRUPTION
Finally, technology itself can weaken intellectual property moats.
Adobe owns the code behind design tools like Adobe Photoshop and Adobe InDesign. For years, if you wanted to do serious design work, you basically had to use Adobe.
Competitors can’t copy Adobe’s code — but they can build alternatives.
Tools like Canva have exploded in popularity by offering simpler, cheaper design software.
Now, artificial intelligence is accelerating that trend. AI tools can generate images, videos, and designs instantly, which means companies relying on traditional creative software will have to evolve quickly to keep their moats intact.
THE FINAL PIECE OF THE MOAT PUZZLE
Over this series, we’ve covered the five major economic moats:
Cost advantage
Brand
Network effects
Switching costs
Intellectual property
There are others, but these are the five that you’ll most commonly find. And, as I’ve mentioned, the strongest companies often combine multiple moats at once.
For example:
A drug company might have patents and brand trust.
A tech company might have network effects and switching costs.
A consumer brand might combine trademarks and brand loyalty.
That’s when the moat starts to look less like a ditch…and more like a medieval fortress.
For investors, understanding how the business actually makes money and spotting these advantages early can make a massive difference. Companies with durable competitive advantages often generate long-term returns through compounding and capital gains.
And that’s exactly the kind of business long-term investors should be hunting for.
Now that you know how to identify them, you’ll start seeing moats everywhere.
See you at the finish line!
