According to these guidelines, Android™ is a trademark that should only refer to compatible versions of Android as described here. My confusion is that the Android Open Source Project's name contains the word Android.
If I were to build the AOSP and make no modifications to it, and did not go through the compatibility process, what would I legally have the right to call what I have compiled? Can I call it "Android Open Source Project," or must I rename it? What do I call AOSP if I have made no modifications to it? Renaming it would cause confusion, while not renaming it would also cause confusion. I can imagine someone going, "Where's the app store?" I'm so confused.
A more careful reading shows that this restriction only applies to "hardware, packaging or marketing materials of device." So in my case, I was fine. I was making a spreadsheet comparing computing platforms' support for various communication protocols. But this still leaves the question of what I call AOSP if I were to sell a hypothetical line of phones running a stock build of AOSP that did not comply with the compatibility specification.
Note: This question was originally posted on the Android Enthusiasts section, but I have relocated it due to being its being off-topic there.
