The United States government is taking exception to Google’s attempt to trademark the word “Glass.” The search giant applied for the trademark last year, but The Wall Street Journal reports the US Patent and Trademark Office objected on two grounds. Firstly, that it would cause confusion between Google’s product and other software and hardware trademarks that use the word and secondly, that the word “glass” is “merely descriptive.” Generic terms generally can’t be trademarked under federal law.
