LegitScript, which has gone after domain name registrars in the past, is sued by supplement makers.
Three supplement makers have sued LegitScript, a company that helps web service providers and banks screen for illegitimate pharmacies and questionable supplements.
SanMedica International LLC, Novex Biotech, LLC, and Carter-Reed Company, LLC allege that LegitScript is wrongfully flagging its products, which is preventing the companies from promoting the products on websites.
Domain name companies are familiar with LegitScript because the group, funded in part by pharmaceutical companies, has gone after registrars that it says were allowing illegitimate online pharmacies to register domain names with them.
In its lawsuit, the plaintiffs say that LegitScript has turned its attention to supplements after mastering the process of taking down bad online pharmacies. They believe that LegitScript uses the wrong criteria to determine if a supplement should be added to its blacklist that is used by companies like Facebook, Google and Visa.
