Rumors about Apple competing in the Electric vehicle space appear to multiply by the day. The latest evidence of a coming Apple Car is the registration of the domain names apple.cars, apple.car and apple.auto. However, a review of pending trademark applications and registrations owned by the Cupertino electronics company doesn't reveal anything yet filed for anything auto related. Similarly, a quick search for pending patent applications with the words vehicle, battery, auto or car reveal patent applications that relate to Apple's in car entertainment system "CarPlay", but nothing that appears to relate to an actual electric Apple Car.
That being said, patent applications are not made public for at least 18 months after filing and Apple has a reputation for secrecy that would make it unlikely to reveal its hand before absolutely necessary. Apple also has a reputation for not worrying too much about others' trademarks when it does not suit them so it could be that Apple is just not that worried about trademark protection at this point.
Others including the Chairman of Daimler and Elon Musk of Tesla believe that Apple is moving ahead on this vehicle with Musk indicating it being obvious due to Apple hiring 1000 engineers to work on it. Given that Apple has not been afraid to enforce its intellectual property, particularly in multiple lawsuits versus Samsung over the look of the iPHONE, the lack of actual IP protection being pursued (i.e., no real patent or trademark applications filed) other than a few domain names that may be just as easily utilized for CARPLAY, is curious but this may just be keeping the world guessing....which going back to the days of Steve Jobs is exactly what Apple likes to do...
