She's not the best, but she has a better understanding of intellectual property law than Posner does. Posner is a brilliant guy, but his ruling in the Oracle v Google case regarding copyright of API's was flat-out wrong.
...
Wholesale copying of an API should be a violation of copyright law and I am hoping Posner's ruling gets appealed sooner rather than later.
Not to take away from the rest of your post, but...
The judge in the Oracle v Google case was William Alsup, not Posner.
Posner's the one who threw out both Motorola and Apple's lawsuits against each other, saying that neither side could prove they had actually suffered any damages... and that even if they had, granting injunctions to either one of them would be far worse.
Like many, Posner basically believes that the patent system is out of control, is being used to smother innovation instead of encourage it, that patent cases are being used to block competition, and that patent cases are being decided by people totally unqualified in the fields being discussed.
