As Android Police's unofficial person who knows things about laws (as always, none of this is legal advice), sometimes I see law stuff going on in the tech world that just makes me mad. This is one of those times. Appigo, an iOS and OS X developer, filed for a trademark on the word "Todo" (see it here) under the scope of a software application (basically).
Yesterday, we received an email from a developer of an app for Android called Star Trek ToDo Agenda. He was contacted by Appigo, with the following email (private information redacted):
I'd like to discuss a small issue with one of your apps:
Your App Name: Star Trek ToDo Agenda
