Amazon Kindle dual-screen e-reader patent granted, Nook potentially in trouble

Who cares about the Nook? There's only one competing product on Amazon's mind at this point (I'm guessing).

I care about the nook, it's a great eReader, and I use it daily. I suppose you're referring to the iPad, which isn't an eReader.

It's not an e-reader but you sure can read on it. And when you're done reading you can watch something. Or listen to music. Or play a game.

If you only want to read then the Kindle and Nook are great devices. As always it's entirely subjective and depends on what you personally want from the device (and how much you want to spend).

How does this effect the kno? http://www.kno.com/

Not at all I imagine. Doesn't seem to use e-ink / electronic paper, just dual LCDs. Not available yet either, looks like they just have prototypes so far.

Cool device though. If/when it ships it looks like it would satisfy most who were interested in Microsoft Courier.

The portion seen as potentially threatening to the Nook:

> A handheld electronic device comprising: a housing; an electronic paper display disposed in the housing and having a first surface area; and a liquid crystal display (LCD) disposed in the housing proximate the electronic paper display, the LCD having a second surface area that is smaller than the first surface area of the electronic paper display.

Except that, if that quote accurately describes the patent, the Nook has prior art given that this patent was granted June 6, 2010. If anything, this is potential trouble for Amazon, as they could stand to be sued.

That said, it's a single quote from a patent. Things are never what they seem; patent trolling wouldn't be profitable if they were.

IANAL, but in the US the relavant date is the invention of the patented item and not the date the patent was granted, so B&N would have to show prior art from many years ago.

Here's the link and the header:

  Inventors: Zehr; Gregg (Los Gatos, CA), Whitehorn; Symon J. (Los Gatos, CA)
  Assignee: Amazon Technologies, Inc. (Seattle, WA)
  Appl. No.: 11/277,893
  Filed: March 29, 2006

But... the Nook existed prior to this patent by >6 months, implying at least a couple years of development prior to the patent. Amazon hasn't made anything with an Eink+LCD. Effectively, Amazon is trying to patent something currently selling. It'd be like my getting a patent, right now, for some major feature of the iPhone 4.

As msg points out, the patent was _submitted_ in 2006. That's the date that matters for determining "who was first?".

Also, you don't have to actually create the product to receive the patent for it. The idea is that the patent protects your right to build said product, without worrying about a faster competitor beating you to the punch.

I'm not saying I agree with how the patent system works, but how I understand it, Amazon's patent isn't affected by any product released after they submitted the patent request.

Actually, in the US, the "who was first?" date is the date of invention, not the date of patent application submission. Of course, it's not always easy to prove that you invented something on a particular date, say, a date before your competitor submitted their patent application. It's especially difficult if you've been developing an idea in secret for some time before applying for the patent (though I believe there's an 18 month grace period before the USPTO will publish your patent application filing).

Or so a patent lawyer told me, anyway. It's possible I misunderstood something.

The accepted method is to log it into a patent notebook (bound book with numbered pages), and get it co-signed by someone knowledgeable enough to testify in court about the content. Signature should say 'read and understood'. This book makes good reading: Laser: The Inventor, the Nobel Laureate, and the Thirty-Year Patent War

A much better way to establish priority is to file a provisional patent, good for a year.

The book "Patent it yourself" makes good reading - not as good as working with a patent attorney, but a lot cheaper.

I suspect that'd be vulnerable to a smear attack from rich, interested opponents. It's your (two) word(s) against their patent. Better, certainly, but not iron-clad.

Sans getting it notarized, of course. But that costs time and money too.

Out of curiosity: could you prove it by sending an email to a system you don't control, like Gmail? If you kept gmail logs of your creations / thoughts, and can't fake the date, it seems to me that'd be proof.

Or can you fake the date with Gmail? If so, know of a possible alternative? I'll probably end up using it.

Ah, my mistake. Didn't know the submitted date.
