Apple contemplates head-mounted iPhone display, America cringes

We're pretty sure this isn't an April Fool's joke, and we're pretty sure that it could be. Essentially an iPhone dock that sits on your face like a pair of glasses, "Head-Mounted Display Apparatus for Retaining a Portable Electronic Device with Display" details a headset that contains a stereo display and either a camera or a window for your phone's camera. Also included in the patent application is a microphone, speaker, batteries, and an accelerometer for detecting the user's head movements. Something like this would be great for augmented reality applications -- and something like this would make ever getting a date that much more difficult. We'll let you know if this one ever makes it past the drawing board, folks.

Motorola patent application offers new option for 3D cellphones

Flip phones may be somewhat on the outs these days (at least among those demanding the latest and greatest), but they may well be the key to future 3D cellphones -- at least if this Motorola patent application is any indication. The basic idea is actually a fairly simple one: you'd see a regular 2D image on the screen when the cover is open, but when it's closed you'd be able to look through the transparent lid and see the images with a "three dimensional appearance." As you can probably figure out, that screen would be a touchscreen that takes the place of a keypad, and another illustration also shows that the same idea could be applied to a slider phone. Of course, what the illustrations don't show is how effective that three dimensional appearance would actually be, although it seems like it could give Motoblur a whole new meaning.

Microsoft seeking patent for Windows Phone 7 Series panoramic GUI

The US Patents and Trademark Office has today made public a Microsoft patent application (serial no. 240,729) related to the graphical user interface found on the hotly anticipated Windows Phone 7 Series mobile OS. Filed in September 2008, this application describes a "contiguous background" that extends beyond the dimensions of the screen (either vertically or horizontally, but not both) with anchored "mixed-media" elements being littered atop it -- all of which is to be served on a "media-playing device." That should sound pretty familiar, given that it's the central navigational concept of both Windows Phone 7 and the Zune HD, and as such it makes a lot of sense for Microsoft to seek to legally protect its uniqueness. Before you start wondering about potential conflicts with other UIs, take note that this requires a continuous graphical background rather than a tiled or repeating image, plus space-orientating graphical elements, which should make it sufficiently nuanced to avoid any more patently unnecessary squabbles should Microsoft's claims be validated by the USPTO.

Pixel Qi and OLPC to share all current and future screen tech

Our man Nicholas Negroponte was certainly excited about pushing the state of the art forward with future versions of the OLPC when we hosted him on The Engadget Show earlier this month, and now he's got one more tool to help make that happen: the OLPC Foundation and Pixel Qi just signed a permanent and free cross-license on a slew of next-generation screen technology patents, including Pixel Qi's sweet dual-mode displays. If you're recall, Pixel Qi's Mary Lou Jepson actually developed part of the 3Qi screen tech while at OLPC, so there was some mild confusion over who owned what -- but the two organizations have solved that problem by cross-licensing all future and current IP covering multi-mode screens. See, it's easy for two tech companies to get along... especially when one is actually a charity that's not at all concerned with profits. Super simple. So -- let's get working on that OLPC XO-3, shall we?

Microsoft facing patent lawsuit over Zune Buy From FM feature

Looks like someone at Microsoft should be paying slightly more attention to the mail: an ophthalmologist (yes, that's right) in Illinois named Edward Yavitz is suing Redmond over the Zune's Buy From FM feature, saying he wrote the software giant a letter in 2006 that disclosed his two relevant patents on the tech, suggested how it could be integrated into the Zune, and asked for a deal. Two years and presumably zero replies later, a young Joe Belfiore introduced Buy From FM along with the Zune 3.0 software, which Ed says directly infringes on his patents -- and his lawsuit, filed ten days ago, asks the court to permanently stop sales of the Zune and award him triple damages in cash. Oops. We haven't dived too deeply into the patents themselves, but it looks like Ed's going to have a bit of a fight on his hands here, as the patents seem to describe systems that have preloaded content about music that's then accessed when a data trigger is received over the air, not just storing song information for later purchase over the Internet. We're sure the good doctor's attorneys have some high-powered arguments to the contrary, so we'll withhold judgment and see where this all leads -- we're guessing a quick settlement is in the cards, as fighting Microsoft might end up actually costing more than any percentage of royalties on total sales of the Zune.

P.S.- If you're wondering why Apple hasn't been named for its similar iTunes Tagging feature... well, so are we. We'll see what happens.
