Motorola Ordered To Recall Android Phones and Tablets In Germany
puddingebola sends word of a German court decision yesterday which found that Google's Motorola Mobility must recall all of its Android tablets and phones that infringe on Apple's patent for "rubber-band" scrolling. From the Guardian:
"The dramatic decision, the latest in an escalating war between Apple and the smartphone and set-top box company MMI, follows earlier cases in which Apple had to disable automatic "push" delivery of email to its iPhone and iPads after MMI won a separate patent fight in Germany. The recall will not take effect immediately because Apple will have to request a ban on specific products and provide a €25m (£20m) bond, while MMI can appeal. However, the court indicated that it was unlikely that an appeal against the validity of the patent would succeed. MMI, with Google's backing, is expected to continue the appeal. The court also ruled that MMI owed Apple damages for past infringement."
Any engineer worth his salt was taught about the time response of second order linear systems - spring, mass, damper. The scroll bounce is just the transient response of such a system to a step function when tuned to be slightly underdamped (light blue line in the figure).
It's obvious as hell and the only reason I can fathom why it's being upheld is because its merits are being judged by people who are clueless about math or engineering. This is as bad as the XOR cursor patent, which was also a patent on the graphical representation of a function widely known and commonly used in the respective industry.
Look at the patent is question. It's an idea, not an implementation. I don't imagine Motorola copied Apple's code to implement it. This is the problem with software patents. Even if Motorola's implementation is vastly more efficient ... still 'infringing'.
