Hmmm not sure what to think of this. Obviously copyright has nothing to do with this except if you consider copying the définitions but by nature those are as public as can be and need to be copied everywhere to make a language usable, but it's not like here java was reimplemented for compatibility reasons but instead they claim to get the mobile os out the door asap, i'm surprised there was such a clear verdict on that with as you mentioned this meaning they get to use for free the design if not the code and that is a sizeable chunk of the work on such a large Library. I'm also surprised it isn't littered with patents (Microsoft had to grant a patent license for mono for exemple).

I wish i could just reimplement .NET anywhere and owe nothing to anyone but i'm pretty sure i can't. Actually even with this verdict i'm still sure i can't with patents.

I do "kinda" feel bad for oracle there, not that their 9bn asking was reasonable but they did have a point, not a full one, not a "you're completely right and Google is wrong" point but definately something.

When I read the jury instructions that were posted publicly on the case, I had a good feeling about it. The instructions were clear on the difference between declarative code defining an interface and functional code defining the working details.

US copyright law carves out an explicit fair use exception for interoperability of computer programs, and the text of that law was also in the jury packet.

It is the same clause in the lexmark v static controls case that allowed them to clone printer cartridges.

Back in the Lexmark v Static Controls case the appeals court wrote that the law clearly allowed all copying for interoperability purposes, otherwise hardware makers could lock their components in illegal ways. That ruling additionally specifically called out automotive parts and video game systems, declaring that copyright protection does not apply to any kind of lockout codes since they are declarative rather than functional. Companies can still attempt to use lockout codes, but they cannot use copyright infringement as a defense if they are broken.

I'm glad the jury was careful about those instructions.

I'm most happy with the current situation personally.

On one hand the appeal court's judgement acknowledges the creative work required to create a good API. I mean, I don't have any respect for the Java Foundation Class' APIs I think they're a mess and I hate every second I spend coding in Java, but when I think of some really well made libraries such as (IMHO) LINQ or the Roslyn API in .NET, all the new modern async Javascript libraries out there, or the thread/promise/future libraries in modern C++, I see a lot of cleverness and creativity in their design and I'm glad that the copyright acknowledges the work that goes into creating them.

At the same time, compatibility between APIs is a sine qua non condition to make software work, to promote competitivity between software providers, for free open source alternatives to work, etc. They have also been used forever, as each piece of software is built on top of another. The fact that using or copying them is fair use is common sense and I can't think of what would have happened to our industry if Oracle had it's way.

So basically if I understand right, it looks like APIs have a copyright but using or implementing them is fair use, making their copyright look kind of symbolic. If my understanding is correct, this is *exactly* how I hoped it'd be.

Also, I really have to raise my hat to the members of the jury for making sense out of very technical computer science concepts such as APIs and object-oriented programming and taking the right decision. I doubt a lot of them were technical people, if any.

Too bad Oracle intends to go in appeal again. Hopefully the appeal court will serve them a legalese translation of "Go f... yourself!" because I'd really like the current state of affairs to stay the way it is.

For me, if APIs could be protected then people will close up valuable interfaces and charge people to connect etc. The IT industry has been built on plugging different systems together and if Oracle won that would break everything. Would be really ugly.

In the end, Sun open sourced the Java interfaces, just a shame it was not a true open licence because this would never have reached this point. The trouble with Oracle is that I am sure they really purchased OpenOffice, Java and MySQL to take control. Now OpenOffice and MySQL are forked and they have lost control of Java, they should have looked at the licenses close before the purchase :)

if supermarkets were invented today people would be trying to patent the use of a door to get in.

What, don't want to pay for my supermarket door patent? Don't worry for the lower budget i also sell a "hole in the wall" patent to get you started, much cheaper!
