body: I am not sure if it's the right place to ask, but I don't find better place .
  
  
  I am holding "`windows`", "apple", "`microsoft`", "`ios`" and lots of other trademarked names on pypi.
  
  
  **Microsoft** contacted me and asked me to hand over the ownership of those names. Of course I will do that as they asked me politely. But they warn me that Microsoft may consider legal action.
  
  
  My question is, Is this an obligation? Can they actually file for open source package names? And what if I don't want to handover? (As I said I am just curious about the topic)
  
  
  ps: If this question is off topic , please guide me.
