Yes, but we know that doesn't always happen (and demonstrably isn't happening in some of Apple's lawsuits).
> It's worth noting that Apple suing over superficial things is more about preventing direct imitation. They aren't trying to kill their competitors by claiming fundamental technologies. I think this is actually evidence of a moderate approach.
That's not true. Apple is suing over plenty of fundamental, ridiculously broad patents as well, but (with the exception of the "clickable-actions-in-text" patent) we happen to not be talking about them here (in part because Apple lost on some of the more fundamental patents they've asserted).
Here's an article from two months ago that describes some of what Apple is suing over:
http://arstechnica.com/apple/news/2011/12/apples-first-major...
Quoting the article we have:
- "one on layering an object oriented application on top of a procedural operating system (i.e. Mac OS X on top of UNIX)"
- "a method for dynamic object message passing translation"
- "automatically recognizing certain data structures and offering actions for that data (i.e. "Data Detectors")" (what I've described as "clickable-actions-in-text")
- "a method for performing realtime signal processing within a non-realtime OS"
Apple happened to lose at the ITC on 3 of these 4 (the only one still standing is "Data Detectors"/"clickable-actions-in-text"), but this is clear evidence that Apple is suing over fundamental technologies (I'd say fundamental ideas, which is even worse) as well as superficial ones. Given that "Data Detectors" dates back to the Power Macintosh help system, I suspect Apple is using every bit of patent ammunition they have. I certainly don't see any evidence here that Apple is showing restraint.
I'll emphasize again that "Data Detectors" is something that virtually every email client since the mid-to-late 90s does when they make URLs and email addresses clickable, specifically because the idea is so obvious and obviously useful. Should they all have to stop because Apple took an obvious idea to the patent office first? Even when Netscape did it months before Apple in Netscape Navigator 2.0b1?
Oh, I almost forgot. HN just infringed on Apple's "Data Detectors" patent here. Should they stop?
