Ozempic vs. the Copycats: How Novo Nordisk Uses Trademarks to Guard a Blockbuster Drug

How Trademarks Became Ozempic’s Strongest Defense

Ozempic and Wegovy are no longer just prescription medications. They’ve become household names, shaping conversations about weight loss, health, and even culture. This level of recognition carries both opportunity and risk. For Novo Nordisk, the company behind these drugs, trademark enforcement has become a central strategy to protect both its brand identity and its market position.

In the U.S., trademarks serve a unique role in pharmaceuticals. They don’t protect the chemical formula (that’s patent law’s job), but they safeguard the name, the identifier that consumers and healthcare professionals rely on. When demand spikes, as it has with Ozempic and Wegovy, unauthorized sellers try to cash in, creating legal conflicts that hinge on trademark law.

The Surge of Counterfeit and Compounded Products

The popularity of semaglutide-based drugs has led to a gray market. Clinics, med spas, and online providers promote “compounded” or imitation versions of Ozempic and Wegovy. While the FDA has raised safety concerns about these products, Novo Nordisk has taken matters further by pursuing legal remedies.

In 2025, Novo Nordisk filed more than 130 trademark lawsuits in over 40 states against businesses that used the Ozempic or Wegovy names in marketing unauthorized products. The claim is straightforward: using these marks misleads consumers into believing they are receiving FDA-approved drugs from the genuine source.

Why Trademark Enforcement Works in Pharma

Trademarks give Novo Nordisk a faster, more direct legal path than waiting on regulatory enforcement. Under U.S. law, a trademark owner can seek injunctions to immediately stop infringing use and recover damages. For a drug as visible as Ozempic, this approach makes sense:

  • Consumer trust: Patients must believe they are receiving authentic, safe medication. Misuse of the trademark erodes that trust.

  • Brand exclusivity: The Ozempic name itself has become a cultural reference point. Novo Nordisk protects its ability to control where and how it appears.

  • Market control: By shutting down unauthorized sellers, the company keeps competitors from riding the coattails of its marketing and R&D investment.

This approach mirrors strategies in luxury fashion, where companies aggressively police brand names to maintain prestige and value.

Lessons for Brand Strategy

The Ozempic story highlights lessons for any business, not just pharmaceutical giants:

  1. Trademark early and broadly
    Novo Nordisk didn’t only register Ozempic in the U.S. but pursued protections in multiple jurisdictions and for multiple uses. This foresight gave it leverage across courts and marketplaces.

  2. Monitor the marketplace
    The company’s legal actions were proactive. They tracked down businesses misusing the marks online and offline, then acted quickly.

  3. Use trademarks to reinforce brand value
    The more popular a name becomes, the more important it is to defend it. Failure to enforce trademarks can lead to dilution, weakening a brand’s legal protection.

  4. Balance legal with PR
    In pharmaceuticals, enforcement also carries reputational risk. Novo Nordisk framed its lawsuits around patient safety as much as brand protection, aligning legal action with public interest.

U.S. Trademark Law Nuances

From a legal standpoint, the Novo Nordisk lawsuits hinge on two key doctrines under the Lanham Act:

  • Likelihood of confusion: If consumers believe compounded products marketed under “Ozempic” are authentic, that creates liability.

  • Dilution: Even without direct competition, widespread unauthorized use of a famous mark can weaken its distinctiveness.

These doctrines make trademark law especially powerful for protecting well-known drug brands, even before harm occurs.

The Business Impact

The lawsuits shape Novo Nordisk’s competitive advantage. By policing use of its trademarks, the company:

  • Preserves the premium pricing power of its drugs.

  • Strengthens negotiating leverage with insurers and healthcare systems.

  • Protects its position in upcoming patent cliffs, where the brand name may carry more weight than the underlying formula.

For other pharmaceutical companies, the lesson is clear: trademarks are more than a formality. They are strategic tools in managing competition, compliance, and consumer trust.

Trademarks as the Silent Power in Pharma

Ozempic and Wegovy illustrate how trademarks transform from legal filings into business assets with cultural weight. By enforcing its rights aggressively, Novo Nordisk is not only protecting its bottom line but also shaping how the public perceives its brand.

In an industry where a single name can carry billions in brand equity, the trademark is no longer a secondary consideration. It is central to strategy.

FAQs About Trademarking a Business Name

  • You apply through the U.S. Patent and Trademark Office (USPTO), providing details about your business, your mark, and the goods or services you offer. Once approved, your name is legally protected.

  • File an application with the USPTO online, select the correct class of goods or services, and pay the required filing fees. Legal assistance helps avoid mistakes.

  • Search to ensure the name isn’t already taken, then file with the USPTO. After examination and possible publication for opposition, the USPTO grants registration.

  • A trademark is a legal right protecting names, logos, or symbols that identify and distinguish a brand’s goods or services.

  • It prevents others from using your name, gives you nationwide protection, and adds credibility when building your brand.

  • Without a trademark, your business name has limited legal protection. Registration helps you enforce your rights if competitors copy or misuse your name.
