Update: see the comment on the final judgment on the copyright protection of the API.
There has been a lot of noise in some areas of the Internet around what to make of the verdict that the jury has taken in the Oracle v. Google case.
For the benefit of the readers, here the questions and what the jury has answered. For Europeans, it is very odd to see a jury to decide in matters that are strongly legal in nature, but that's how it goes up there. Bear in mind, though, that the jury is only responsible for the assessment of the facts, it's up to the judge to have a final say about the law.
Also, bear in mind that the judge has instructed the jury to decide as if the API (Application Programming Interfaces) are a copyright subject, but that is just a speculative statement, the matter will be settled by the judge in its final decision.
