If you don't mind expanding, interested to hear why you believe the current ruling should be overturned.
This is in direct contrast to decades of consensus that APIs are not copyrightable, and furthermore, there is a particular procedure to go through [clean room technique, which Google did] to ensure that the API is reimplemented without infringing any copyright.
Letting this ruling stand would mean that nearly every piece of software you use infringed someone's copyright.
*corrected from "second district court"
More: Recall that copyright lasts close to forever. (95 years for corporations, if I recall correctly.) This ruling, then, would have allowed IBM to sue every BIOS clone maker, and keep a stranglehold on the PC market, and still have that stranglehold to this day, and be able to keep it until 2076. Then, on August 2, 2076, then we could get IBM-compatible PCs.
Compare that to actual history, and you can see why I think the current ruling is horrible.
