Given the current ruling in Oracle v. Google, though, I'd imagine Smartcar would have grounds for a legal case. If Oracle is awarded damages from Google for "copying" the Java API specification in Android, even with a different underlying implementation, then I'd imagine Smartcar can highlight the similarities to their own dispute with Otonomo. The tricky thing is it looks like Otonomo is an Israeli company so I'm not familiar with how US court rulings apply across international boundaries -- perhaps at the very least Smartcar can attain an injunction against Otonomo within the US.
