Well good news is that it is not a granted patent yet. Although it looks like Apple is fighting it to the teeth and most likely discussing reduction of claims (check the PAIR system). Regardless if its a patent or not, what is being described here doesn't seem to be infringing on the patent anyway. See the first Claim #1: PART1 <storing a device-independent intermediate representation of a source code; > and PART2 < in the event an indication is received that the source code has changed, using the changed source code to generate and store a new intermediate representation of the changed source code.> If I understood correctly, only thing you would be doing is the PART1 hence you are NOT infridging on the patent. IMHO Disclaimer= not a lawyer, dont follow any advice you see here ;-P
