Today, the US Patent & Trademark Office published an official letter that was sent to Apple regarding their trademark application for "Touch ID" having been refused by their trademark examiner. Noteworthy is the fact that the letter was originally sent to Apple on May 7 and only made public today. That's over a two month delay. The case against Apple's Touch ID being registered seems to be solid and valid. Apple officially has six months to reply to USPTO with a work-around remedy or risk automatic trademark abandonment. With Apple likely to add their Touch ID feature to new iPads this fall, it'll be interesting to see how Apple reacts to this latest news.
