Only one problem with your statement. Google has never initiated a lawsuit against Apple.
Is that perhaps because Apple has never infringed upon any patents Google holds? Or perhaps Apple has paid appropriate licensing fees in order to use certain patents?
Everyone is quick to point out that Apple is the evil, lawsuit happy corporation and Google is some white knight that doesn't care....
Truth is - Apple holds a vast array of patents (regardless of how they came by them, Apple holds them) that were granted by the USPO (whether or not some should have been granted is beside the point). Samsung and others have directly infringed on said patents without entering into any kind of licensing agreement. Apple sues. Notice that other companies like HTC are able to work out deals with Apple that allows the HTCs to use said patents.
Google holds plenty of patents in its own right - but Apple has never been sued for infringing. Now we could assume this means Apple hasn't infringed upon any Google patents (the most logical choice if you leave bias out of it). Or like many irrational people here, we could say that Google is some altruistic billion dollar ad corporation that simply chooses not to sue out of the goodness of their hearts, despite infringement by Apple.
Take off the blinders people....Apple simply follows the rules.
Now we could argue whether those rules are right or fair, but that doesn't negate the fact that as currently instituted Apple isn't doing anything wrong - by suing or in the fact that they aren't infringing (on Google's patents - Apple has been sued PLENTY by other companies).
TBH, I don't really think Google holds many patents that coincide with what Apple is trying to do. Again I'll say, in big bold letters
all these iOS 8 features people are claiming Apple got from Google/Android were actually taken (copied if you must) from 3rd party apps in the jailbreak community and across other OSes.
I'm fully capable of admitting these aren't Apple's ideas. But this perception that Google invents all is getting ridiculous. It's incredibly ironic that some of you here rail against "apple fanboys" for claiming "Apple colored the sky blue" and yet you're doing the exact same thing.

Since we're talking about copying. I found this funny.
There is already an Aussie startup company with the same name as HealthKit.

I hope they sue and give Apple a taste of their own medicine. Nice little payday for them soon maybe in a settlement?
Since Apple has trademarked HealthKit in a number of countries already, my guess is they simply buy this company's name for a hefty sum of money.
