Two related companies are suing Apple over screen rendering technology used in the iPhone and iPod Touch, according to reports.

Picsel Technologies and Picsel Research, based in Glasgow, Scotland, filed a patent-infringement lawsuit Friday in U.S. District Court in Delaware, Dow Jones reported. The suit alleges that Apple is violating a Picsel technology that accelerates the process of updating a device’s display.

According to Macworld, the suit is focused on Picsel technology that people use to zoom and pan documents, sites, and images. Apple’s devices wouldn’t function as fluidly without the technology, alleges Picsel, which wants compensation for devices already sold.

Picsel’s site says its customers include Motorola, Nokia, NTT DoCoMo, Palm, Samsung, Sony Ericsson, and Sharp. According to Dow Jones, Apple declined to comment.

The Electronic Frontier Foundation (EFF) has petitioned the Library of Congress to officially protect phone owners who bypass software restrictions on their phones—aka “jailbreaking.” Apple has just filed an objection, arguing that doing so would infringe on their copyright. If Apple gets its way,

[it] would have the right to claim statutory damages of up to $2,500 “per act of circumvention.” People who jailbreak phones, might even be subject to criminal penalties of as long as five years, if they circumvented copyright for a financial gain.
