No, the argument against injunctive relief was far more complicated and complete than that quote implies. Apple didn't seek relief for loss of royalties, which would give them tangible benefits for injunctive relief. Posner argues that Apple's pursuit of injunctive relief is an attempt at a punitive action in disguise. An "invent around" is trivial in a specific case, and the logistics of forcing of such an invent around would give Apple no benefit other than the punishing of Motorola is the issue.
It might not hurt to give scanning the opinion a try. Call me crazy, but I enjoy reading these things.
