Google already has the trademark for "Google Glass," but is seeking an additional trademark for the word "Glass" by itself, in the futuristic font Google uses in its marketing campaign. According to reports, however, the U.S. Patent and Trademark Office (USPTO) is putting a kink in the company's plans.
The Wall Street Journal published a letter from the USPTO to Google that outlines some of the problems the office has with the request. First, there is an issue that the Glass trademark might be too similar to other glass trademarks since Google's not the first company to apply for a glass trademark. Secondly, even if Google got a trademark on Glass — distinctive font and all — the USPTO doesn't think glass is a term that can be trademarked under federal law, which says that you can't trademark words that describe a product.
