Legal So, Google has finally officially responded (thanks for hosting, Engadget) to Oracle's patent and copyright infringement lawsuit against the search giant's Android mobile operating system. Apart from boatloads of pages on how Google pretty much denies any and all claims, there's a lot of interesting stuff in there - stuff that doesn't seem to bode well if the courts do decide Google is infringing Oracle's patents. It also makes it crystal clear that anyone who values Free and open source software should avoid Oracle products like the plague.

OpenJDK is a procedure/function library used by programs running on the VM.

Dalvik is a VM.

Any patents for Java VM are unlikely to affect Dalvik since they are totally different VMs. Dalvik is closer to the old PCode VM then the Java VM.

The only patents Google has to worry about are the ones covering the Java Standard Libraries (SDK). I'm not sure how you would patent a set of base functions.

Any patents in the Java compiler are also moot. Google doesn't include the compiler. Google has a java-byte-code to dalvik-byte-code compiler. They also have an assembler that generates dalvik-byte-code directly. Also, there are multiple java-byte-code compilers and Android's converter will be happy with the output of any of them.

Harmony doesn't include any Sun source code in the library (it's a clean room version). Google removed the user interface sections of Harmony and replaced them with an Android GUI. Thus they violate no copyrights.

Any patents in Java should be thrown out. You can't patent an abstract idea. Thus, how can you patent an abstract idea running on an abstract machine.
