A man suing Buffalo Wild Wings over their 'boneless wings' has also sued Tom's Mouthwash, KIND granola, and Hefty recycling bags. An attorney says it's possible he's 'just being annoying.'

• A single plaintiff has sued Buffalo Wild Wings and three other companies over the advertising of their products.

• An attorney told Insider these cases may be more "annoying" than productive for consumer advocacy.

• Another attorney questioned whether the plaintiff had suffered real damages in his class-action suits.

A man who made headlines for suing Buffalo Wild Wings for their advertising has sued a bunch of other companies as well, court records show. The pattern has raised eyebrows among legal experts.

Aimen Halim filed his class-action lawsuit against Buffalo Wild Wings on March 17, claiming its "boneless wings" are actually made of chicken breast, which he said amounts to "deceptive marketing," Insider reported last week.

Court records show that Halim has also filed suits against Colgate-Palmolive, the makers of Tom's Wicked Fresh Mouthwash, which he claims is not as "natural" as advertised. He also filed a similar suit against KIND, arguing the "high in fiber" label on their granola is misleading. And in a since-dismissed case against the makers of Hefty recycling bags, Halim argued that the bags are not actually recyclable. 

Spokespersons for the three companies did not respond to Insider's request for comment.

Bill Marler, an attorney who specializes in food safety cases but is not associated with Halim's lawsuits, told Insider that these kinds of cases are often unproductive.

"There's a thin line between consumer advocacy and just being annoying," Marler told Insider. "It raises the issue about what's the real purpose here? Is it that they're being a consumer advocate and then extracting fees and costs out of the company to discourage them from doing it again? Or is it just a tool to extract fees and costs out of a company?"
