We are about to witness an explosion of Lanham Act litigation over fake online reviews. Estimates vary, but at least 50% of American consumers consider online reviews before making a purchase. A couple days ago, I had dinner at Boulud Sud in Miami. Before making reservations, I checked out the reviews online. The reviews were great. I was sold.

Positive reviews drive new business. Negative reviews can be a disaster. Companies are now acutely aware of their online reputations and how that reputation measures up against the competition. In an effort to improve their competitive positions, many companies turn to the dark side: fake reviews. Consider the following: An herbal weight loss supplement we’ll call Magic Lean. In an effort to gain a competitive edge, Magic Lean launches an aggressive campaign of fake online reviews. It creates dozens of glowing reviews hailing its product as, well, magical. Five stars. “I lost 100 pounds on Magic Lean.” At the same time, Magic Lean identifies its biggest rival. It launches a smear campaign of negative reviews on Amazon and other websites. One star. “Terrible product. It gave me the jitters and I actually GAINED weight.” Believe it. This is a growing problem that affects virtually every industry. Scholars estimate that between 15 and 30% of all online reviews are fake. Those fake reviews control literally billions of dollars’ worth of business. Five years ago, this was a back-burner topic. Today, it’s a critical business issue on every company’s radar. The Lanham Act provides a powerful tool for combatting this problem.

The Lanham Act: An Underutilized Tool

The Lanham Act is perhaps the most misunderstood and underutilized weapon in the toolkit for combatting unfair competition. Case in point: We recently sued an industry rival for false advertising under the Lanham Act. In moving to dismiss, the big firm lawyers on the other side spent five pages arguing that our claims should fail because there was no trademark at issue. That’s not unique. These days, I’m filing more and more 43(a) Lanham Act false advertising cases. And almost every time, the defense lawyers have no idea what hit them.

False Advertising: Some Basics

  • You can sue for false advertising via the Lanham Act when there’s no trademark at issue.
  • You can sue industry rivals for advertising that is literally false.
  • You can sue industry rivals for advertising that is literally truebut misleading.
  • Standing is very broad after the Supreme Court’s Lexmark
  • You can sue industry rivals for false statements they make about their own products, whether comparative or non-comparative.
  • You can sue industry rivals for false statements they make about your products, whether comparative or non-comparative.
  • Comparative false-advertising claims are stronger because of damages.

False Advertising & Fake Online Reviews

Let’s go back to the Magic Lean hypothetical. Magic Lean has a problem. Under the Lanham Act, any competitor could sue Magic Lean for making false statements about its own product (e.g. the fake five star reviews). But the strongest case belongs to the rival whose product Magic Lean was disparaging. That case almost certainly survives a motion to dismiss. The real hurdle comes at summary judgment, when the defendant will attack proximate causation and damages.

In most cases, it’s not enough that a defendant is engaging in false advertising. As the plaintiff, you need to show that the defendant’s false advertising proximately caused you harm. That hinges on (1) the specific facts of the case and (2) expert testimony. In the scenario presented above, the right lawyers and the right experts probably have a good shot of getting the case past summary judgment. Remember: There is no one, universal framework for evaluating damages in Lanham Act false advertising cases. The applicable framework depends on the nature of the advertising (e.g. literally false, comparative or non-comparative, etc.). To put it simply: Literally false comparative advertising gives rise to the strongest variant of Lanham Act claim with the most readily provable damages.

Closing Thoughts

Fake online reviews are a multi-billion dollar problem. And that problem is growing. If an industry rival is using fake online reviews to (1) improve its own online reputation or (2) destroy the online reputations of its rivals, those impacted by this sort of misconduct must consider their strategic options. The Lanham Act is the most powerful weapon available to combat this specific type of unfair competition. In the perfect storm, you get damages. Even in a situation where it may be difficult to prove damages, it may be possible to obtain a preliminary or permanent injunction.
