Let's assume Oracle wins on appeal... What's next? Is everyone suddenly writing .Net code? Or are we left to find languages with lapsed copyrights? Fortran IV and Snobol are the new hotness! Everyone in to the pool!
It depends on the details of the ruling (the court could decide to pass such a narrow judgement that it only affects Oracle). Here is an analysis of how the rulings (up until now) affect the software world: http://www.zerobugsandprogramfaster.net/essays/x-1.html
Oh don't worry, Oracle are one step ahead with JavaScript. They launched this Twitter account last week: https://twitter.com/javascript .. and for a week they posted loads of Java stuff on it and haven't failed to point out in replies that they own JavaScript's trademark. The picture of their headquarters is also a nice touch.
Even Fortran, C and C++ compilers depend on the work that a few corporations like Apple, Google, Intel, Microsoft,... put working on the compilers and sending employees to ANSI meetings.
