A Wilton-based attorney has filed a federal lawsuit against a marketing company claiming its website contains false advertising that makes it appear to be run by attorneys.

The civil lawsuit, filed Wednesday in U.S. District Court in Connecticut by attorney Sergei Lemberg of Lemberg Law, claims the owners of eGenerationMarketing are “engaging in a false, misleading and deceptive advertising campaign, which directly impacts consumers in the Connecticut market, and elsewhere.” Lemberg said a big part of his practice is representing clients in Fair Debt Collection Practices Act cases, and that the Boston marketing firm is taking away business.
