Excuse me, but regardless of whether it's copyrights or patents, the original Apple lawsuit was about M$ "stealing" the "look and feel" of the Mac OS. This case was indeed very similar in nature.
BTW: Looking back, it seemes most agree that John Sculley was the worst thing that has ever happened to Apple.
No, they are not similar at all because patents and copyrights are treated on totally different legal grounds.
It's perfectly legitimate and accepted by almost all jurisdictions around the world (as well as jurists) that copyright applies to computer programs, as an expression of art (be it source code itself or the manifestation of such code as a computer program/interface).
Therefore, the lawsuit initiated by Apple was accurate, in the sense that it sought to discuss the licensing terms of the stupid agreement between Apple and MS. MS indeed stole the Apple's System "look and feel", but the judge at that time ruled that, among other things, such similarities were either covered under the licensing terms or not enforceable as an expression of the art as such.
But at least in procedural terms, copyright is and should be used for computer programs. The problem now is that PATENTS are used for the same purposes, disguised behind "novelties" that don't exist, "prior art" that is disregarded, and "industrial application" that is forged to make such fake processes look like real processes. Besides, the protection level of patents is way higher than that given to copyright, equating to a State-granted monopoly for, depending on the jurisdiction, 20 years. If we (and notably USPTO) were to follow patenting requirements, 95% of the software patents should be thrown into the trash, period. And most legal professionals surely know that, even if they don't admit.
p.s.: But yep, Sculley was THE worst CEO, alongside Mr. "Train Wreck" Spindler...he assured revenues for some time, surfing on Apple's previous successes...and then led it to its most grim horizon ever, trying to cover all bases without focusing on nothing at all.
