Irreparable harm seems to imply that this could hurt Apple in a major way.

But it's easy to see what game-changing technology is. Look at what people want in a phone:

There's tens of similar surveys published online. None of them include "search-as-u-go". In fact Apple doesn't seem to think that it's that big enough of a deal to promote. They advertise tens of features & this isn't one of them. And that's because it's expected (everyone uses it already) or it's not that important to a buyer when choosing a phone to purchase.

It's just not reasonable to assume that the "search-as-u-go" technology could give any sort of significant advantage to Samsung to be the cause of a shift in market share or something with similarly unascertainable consequences, which is precisely what the ruling of irreparable damage relies on.
