The trademark testiness of some brands is even extending to meta tags, according to SearchEngineLowdown. It points to a story showing a pharmaceutical company suing its competition for having included "BDI Blood Diagnostics" in its website's HTML. These efforts to prevent the use of trademarks may well fail on the basis that they do not cause real consumer confusion and serve the purpose of allowing patients to conduct better searches on terms such as "alternatives to BDI Blood Diagnostics."
