Pinch-to-Zoom and Rounded Rectangles: What the Jury Didn't Say 147
CharlyFoxtrot writes "Steve Wildstrom at Tech.Pinions takes on some of the what he calls folklore surrounding Apple v Samsung, investigating what was and wasn't part of the case and how the media got it wrong: 'There's one serious problem with the first sentence, which was repeated dozens of times in stories in print and on the Web. Apple only has a limited patent on the pinch to shrink, stretch to zoom gesture that is a core element of touch interfaces. And the 826 patent wasn't in dispute in the Samsung case because Apple never asserted it. In fact, this particular patent does not seem to be in dispute in any litigation.'"

The Apple '915 patent [google.com], which was at issue, does assert a claim to "pinch/zoom." Claim 8 includes:

I submitted this article because firstly this has been such a huge story in the mainstream press that it's good opportunity to investigate how reliable the information coming from them about tech matters is and secondly because there is a lot of confusion even among geeks about what was at stake in this trial resulting in a low signal to noise ratio in the discussions. Personally I do also believe we are at a defining moment in the modern computing industry so even if this lawsuit may end up being of little to no importance the close attention is warranted.

Nilay Patel of the verge, an actual honest-to-god copyright lawyer not just someone who plays an expert on the web, disagrees in his aptly named "The myth of pinch-to-zoom: how a confused media gave Apple something it doesn't own" [theverge.com]:
"So let's just be extremely clear about this: the jury ruled that 21 of 24 accused Samsung phones infringed claim 8 of Apple patent 7,844,915, which specifically covers a programming interface which detects if one finger on a screen is scrolling or two or more fingers are doing something else. It is one possible step along the road to pinch-to-zoom, but it is definitely not pinch-to-zoom itself. And — crucially — it may not be that hard to design around."
Maybe read up there too ?

No, "scaling" is what the interface does as the result of a gesture, pinching is what the fingers do which again is not defined in the document. There's a reason the patent is called "Application programming interfaces for scrolling operations": it focusses on scrolling and how that operation is distinguished from a gesture. And a gesture is just defined as having 2 ore more input points without further elaborating on the state of those input points.
Scrolling is defined in the full patent text [uspto.gov] as :
"Scrolling is the act of sliding a directional (e.g., horizontal or vertical) presentation of content, such as text, drawings, or images, across a screen or display window. In a typical graphical user interface, scrolling is done with the help of a scrollbar or using keyboard shortcuts often the arrow keys. Gesturing is a type of user input with two or more input points. Animating operations include changing content within a given time period."
So, they only mention the 2 axis.

Very interesting interview [bbc.co.uk] with the jury foreman on the BBC.
Especially his statements like:
"The jurors wanted to send a message to the industry at large..."
"And in example after example, when we put it to the test, the older prior art was just that. Not that there's anything [wrong] with older prior art - but the key was that the hardware was different, the software was an entirely different methodology, and the more modern software could not be loaded onto the older example and be run without error."
"And so consequently, when we looked at the source code - I was able to read source code - I showed the jurors that the two methods in software were not the same, nor could they be interchangeable because the hardware that was involved between the old processor and the new processor - you couldn't load the new software methodology in the old system and expect that it was going to work. And the converse of that was true."
I hope Samsung's lawyers are watching.

Read the patent. No, really, it's enlightening and a propos to any discussion on the subject.
It does not claim the "tap-to-zoom" gesture as novel. It claims a specific mechanism that describes how to determine which parts to zoom, when to zoom in or out, and on which part to focus and center; all using various methods and heuristics to determine user intent.
Have you noticed that in say, Mobile Safari, when you double-tap to zoom it doesn't just "zoom in"; it tries to determine which is the relevant content block that the user is selecting and magnifies that, often at the exclusion of the surrounding content. The mechanisms to determine what to do and how to do that is what is claimed in the patent.
The prior art on "tap-to-zoom" is precisely a non-contextual and non-discriminating magnification at the point of contact; which is different.
Yes, reading, it's a dangerous thing.
