Judge Leonie Brinkema of the U.S. District Court for the Eastern District of Virginia granted Google's motion to dismiss a trademark-infringement complaint brought by Geico. The insurance company had charged Google with violating its trademarks by using the word "Geico" to trigger rival ads in sponsored search results. Geico claimed the practice diluted its trademarks and caused consumer confusion.
The judge said that "as a matter of law it is not trademark infringement to use trademarks as keywords to trigger advertising," said Michael Page, a partner at Keker & Van Nest, which represented Google.
The ruling is a triumph for Google in that it derives as much as 95 percent of its advertising revenue from keyword-triggered ads, which appear next to Web search results. Trademarks play a central role to the sale of such ads because people often use Web search to find products and services with common, trademarked brand names such as Nike or Geico.
The ruling also could inform similar trademark-infringement cases online, legal experts say. For example, Google is being sued by American Blind and Wallpaper for trademark infringement by its keyword ad program.
