False Advertising

Misrepresentation of a product or service is as old as time—but in an age where e-commerce sites can generate hundreds of thousands of sales per day or hour, false statements in advertising and product labeling can quickly cause massive harm. Kronenberger Rosenfeld's false advertising lawyers have litigated and won false advertising cases in the quickly evolving realm of internet marketing and sales under both state and federal law. We use our deep litigation experience and extensive knowledge of advertising technology to give our clients a significant advantage in these matters.

False advertising can be particularly harmful when it occurs on the internet.

There are a variety of types of false advertising on the internet. For example, a company may be engaging in false advertising if it makes false statements about a competitor or if it makes false statements about its own products or services.

We have deep and broad experience in handling false advertising cases occurring on websites, in social media, and in mobile apps. Contact our team of false advertising lawyers to learn more.

The concept of false advertising appears in a variety of federal and state laws. Generally under these laws, “false advertising” refers to a representation or omission that is likely to mislead a consumer who is acting reasonably under the circumstances. These state and federal laws exist to safeguard consumers from being misled, as well as protect competitors from inaccurate statements that would tarnish their brands, goods, or services.


If a competitor steps over the line and engages in false advertising, there are remedies available under federal and state laws. Injunctive relief (i.e. a permanent judicial order to cease and desist from certain activities deemed to be false advertising), actual damages in the form of disgorgement of profits, and monetary amounts to fund corrective advertising are examples of potential remedies against competitors who engage in false advertising. Consumers also have standing to sue under most state false advertising statutes.


At the federal level, the Federal Trade Commission (FTC) is the agency responsible for investigating false advertising and prosecuting actions against false advertisers. At the state level, state Attorneys General take the lead role in such investigations and prosecutions. Our team of false advertising lawyers at Kronenberger Rosenfeld has experience representing clients who are under FTC or state attorney general investigations and working with these government organizations to achieve fast and sensible solutions.

Kronenberger Rosenfeld has experience litigating unique & challenging cases, and we are eager to discuss any false advertising issues you may have. Please use our easy online case submission form or contact us via phone at (415) 955-1155, ext. 120
