Apple on Tuesday was granted a utility patent from the U.S. Patent and Trademark Office covering the glass-on-metal trackpad seen across the company's laptop lineup, with the award coming almost four months after the design rights were garnered for the same invention.

Apple's U.S. Patent No. 8,441,450 for a "Movable track pad with added functionality" is actually a wide-ranging property covering a number of design variations from the trackpad MacBook Pro and Air user have come to know. In January, Apple won a design patent for the glass-on-metal trackpad as used in the first unibody MacBook.

The idea itself is simple: to dispose a trackpad onto a surface with a hinged fixed at one end, allowing the unit to move from a neutral position, to an active position, and back. In essence, the entire trackpad becomes a large cantilevered button.

More importantly, the patent calls for, in one embodiment, a capacitive track pad with an etched glass surface. Because of its unique properties, and its non-conductive nature, glass allows for high levels of control during the manufacturing process.

The patent language describes a multi-touch enabled trackpad with one end attached to via a hinge mechanism to a laptop chassis. When a sufficient amount of force is applied to the unit, it moves to register an input signal through an integrated circuit board. Once the force is removed, the flexure hinge returns the trackpad to its resting position.

Trackpad


Apple points out that such a design could not be implemented prior to modern miniaturization techniques as the required springs and integrated circuitry would be too large to fit into the small space required by a thin laptop.

As for the choice of glass as the dielectric layer, or the non-conductive material which sits atop the capacitive touch panel, the material proves to be both structurally stable and highly customizable.

Trackpad


For example, traditional glass has a surface with a high friction coefficient, meaning it resists slippage, making it a less than suitable candidate for trackpad use. However, glass can be made to have a low friction coefficient by etching, sand-blasting, honing, or other methods. This makes the surface smooth and easy to navigate with a finger.

In the case of Apple's trackpad, a multi-step process of "seeding" the surface through mechanical or chemical etching, followed by a wet polishing with an acid solution is employed to achieve the proper finish.

Trackpad


Apple notes that the capacitive trackpad can be employed in a any number of devices, including standalone peripherals and smartphones. Such a "push screen" design was used by certain handset makers as a means of input, though the idea ultimately gave way to multi-touch gestures.

Also mentioned was the inclusion of LEDs or a display being disposed beneath the glass layer, an idea that has long been rumored to be included in a future MacBook since Apple first introduced the glass trackpad in late 2008. The company even holds a number of patents pointing to such a device.

Apple's trackpad patent was first filed for in 2008 and credits Brett William Degner, Patrick Kessler, Chris A. Ligtenberg, Thomas W. Wilson, Jr., Bartley K. Andre and Matthew P. Casebolt; Matthew as its inventors.

    Apple's trackpad is still one of the best design and function products around.  No other competitor comes even close.  It's pure elegance between software and hardware.



    It just goes to show the sloppiness and ineptitude of the PC industry.  Not only can they not get the hardware as polished as Apple's, but the botched drivers and half-a$$ed implementation is downright shameful.  By the time someone gets even remotely close, the product is discontinued to make way for their next disposable generation device and re-invent the wheel.



    That's the PC industry in general. They make everything, but can't do one thing well.

    Same can be said of the Android army too. image

    The best thing about Apple's trackpad is the size.  It's definitely the best on the market.

    The PC industry's answer is making the entire screen a trackpad, so the user can get Monkey Grip.

    Yeah, I've used a friend's HP and Toshiba laptops and they sucked. The HP was HORRIBLE.  Just a REALLY bad track pad.  He had some really pathetic puny mouse that was just as bad.  it was one of those mouse with a BlueTooth stick because the laptop didn't have Bluetooth.  And we wonder why HP is not doing very well.  They've had some really badly designed products.  HP used to have decent stuff, but trackpad drivers for Windows has always been poor.  Very touchy.  Those Thinkpad eraser devices are even worse.  I had to suffer with one of those for about a year.  Horrible innovation.

    Yes, the trackpad is totally ignored by anti-apple fanboys, but it truly is an amazing piece of tech. The hardware and the software behind it are essential to making the OSX experience so good.

    I think you're talking about IBM's trackpoint or Dell's track stick, that's located in the middle of the keyboard.


    I personally love the the trackpoint/track stick and won't even consider a laptop that doesn't have one.

    When I got my first Apple laptop a few years ago, the trackpad was probably what impressed me the most.  After years of laughing at PC trackpads and their apparent uselessness, I couldn't believe how good Apple's implementation was; I had thought all trackpads had to be horrible by design.

    I bought my wife a Lenovo laptop a few months ago.  My daughter has an Air but I don't get to use it often enough to do a comparison of trackpads.  I can say though, that the lenovo trackpad certainly isn't perfect by any stretch.  Along with windows 8 the laptop is frustrating to use.

    I hope they put this technology into the IOS home button, This would be very helpful if they ever make a Mac OS on IOS devices, or made a IOS Laptop like design. Obviously I am pointing out that this Mac trackpad, like the keyboard work on IOS devices.(hardware based software).

    I have spoken with Apple's IP attorneys, one who even threatened me, as well as Steve Jobs before he passed away via email.  Apple DID NOT invent the Magic TrackPad.  I did, and have the proof to support my claim.  What I was never able to do was to find an attorney or group of attorneys who were willing to take on the giant, Apple.  If anyone is interested in where the idea originated from back in September 2007, just let me know.  They "borrowed" my invention and now claim "Apple's trackpad patent was first filed for in 2008 and credits Brett William Degner, Patrick Kessler, Chris A. Ligtenberg, Thomas W. Wilson, Jr., Bartley K. Andre and Matthew P. Casebolt; Matthew as its inventors."  This is flattly false.  It began with an email from me to Apple's IP attorneys asking if they had an interest in what I called the "Wireless mouse pad."  So the giant Apple wins again.  I would love to polygraph all of these purported "INVENTORS."

    My initial email, minus my telephone number:

    "From: "David Land" <[email protected]>

    Date: September 15, 2007 8:19:36 AM CDT

    Subject: Wireless mouse pad

     

    Good morning, I am a die hard Apple / Mac user and have been working on a very basic idea which has gleaned much support form those I have shared with.  I have been working on a wireless mouse pad not too dissimilar from the touch pads used on Apple or any other laptop systems today.  The chief difference is that it remains flat allowing for greater ease of use and greater comfort for the user. In short it is a wireless mouse pad which can be used with any Apple/Mac without the need of a wired device.  Using touch screen technologies, the user is now able to navigate on a Imac, Laptop, or any other computing system developed by Apple, but without the ergonomic issues associated with holding a traditional mouse.  Additionally, the wireless mouse pad can use biometric authentication to grant access to the system.  I have not shared this idea/invention with any other vendor, though I have been approached by several who would like to fund this effort.  I have however, given my love for your (Apple's) systems chosen to broach this idea with Apple first.  Please advise if there is any level of interest in my invention and whether Apple is willing to pursue such a device for incorporation into their suite of technologies.  Please note that I have not yet patented this idea as I am not overly affluent, but I do have a copyright for my invention."

    Kind regards,

    David A. Land

    I can't tell if the guy above is just being  funny but idea is not an invention, and thus it is not right for Apple to pubclicily credit someone for a mere idea. Apple produce a working product with a real result with their own invention. People who worked hard to create this, not from a short email from unknown person.
