Pending Lawsuit against Apple for patent infringement

[Pac3comm1]

A new lawsuit takes aim at the accelerometer- and gyroscope-powered abilities of Apple's iPhone 4, alleging that the interactive, three-dimensional input methods are in violation of a U.S. patent.

The lawsuit, filed this week by Triton Tech of Texas, names both Apple and Nintendo as defendants. Triton is the owner of U.S. Patent No. 5,181,181, entitled "Computer Apparatus Input Device for Three-Dimensional Information."

That patent describes a handheld device that includes multiple accelerometers and angular rate sensors for detecting positioning and motion. By interpreting acceleration, velocity and relative position of the device, it can allow users to interact with a computer or other device with six degrees of motion in a three-dimensional space.

Illustrations that accompany the patent show a mouse with three buttons, and the filing specifically mentions a "mouse" that senses motion in six axes.

Triton's lawsuit only specifically singles out the iPhone 4 from Apple as an infringing device, though it implies that other devices could be in violation. Apple's iPod touch and iPad also include accelerometers that are used for input.

The iPhone 4 also includes a new gyroscope that is not yet found in other iOS-based mobile devices. The gyroscope allows for even more precise motion-based controls, particularly in games available on the App Store.

The suit asserts that the iPhone 4 is in violation because the hardware is "using acceleration sensors and rotational rate sensors for detecting motion about a particular axis for communication with a computing device." It notes that Apple's handset accomplishes this task without approval or licensing from Triton.

Also named in the lawsuit is the Nintendo Wii Motion Plus gaming accessory, which allows users to experience even more precise input via an attachment to the Wii remote control.

The complaint was filed Monday in a U.S. District Court in the Eastern District of Texas. Patent lawsuits are often filed there in hopes of a favorable outcome.

Open for discussion. Tell me what you think?

Well It will probably get settled out of court I would imagine. I dont really know who this company is, but there are alot of people out there that just buy patents and sue companies for infringing on the patent. but since we're in America we can sue for anything and everything so LET THE SUEING BEGIN!

Do you have a mouse in your pocket? Who all is included in this 'we' reference?

I think the patent office never should have allowed such a broad/vague instrument to be patented. I would rank this up there with getting a patent for "a honed instrument used to alter various materials, blah blah", i.e. a blade.

I have not read the patent itself, so I am uncertain how much commonality there truly is between the two concepts.

The patent should also state exactly how the information is transmitted, interpreted and used right down to sampling rate and most any small change in any of these things would also exclude the new concept/device from being covered under the existing patent.

:^/ It's not quite so simple, guys. If the Patent Office didn't protect inventor's creations from infringement, people would be discouraged from inventing new things, and a lot of the technology that we take for granted today would never have existed. Also, requiring patents to be defined too narrowly would mean that I could start manufacturing my own iPhones, except with different colored cases, and it wouldn't be an infringement of Apple's patents because they only patented the silver ones....

No, just because the general public hasn't heard of this company before doesn't make them scammers or charlatans.
