A consulting firm that makes its living in the ethics business has sued one of its rivals for trademark infringement, accusing the second ethics consulting firm of stealing away customers via bogus Google search results.

Corpedia filed a lawsuit on Dec. 18 against ethics and legal compliance company LRN, alleging that LRN purchased Corpedia’s federally registered trade name as a Google-sponsored ad. As a result, when clients searched for “Corpedia” on Google, the top result of their search would be a link diverting them to LRN’s Website.
