Apple and others sued for patent infringement

It's all about the pixels
Tue Mar 22 2011, 10:14

IMPERIUM HOLDINGS has unleashed the legal hounds on Apple, LG, RIM, Nokia, Motorola, Sony Ericsson and Kyocera, claiming that they have all infringed a number of its patents.

The patents in question are US Patent Numbers 6271884, 6838651, 6838715, and 7064768, all of which relate to pixel and imager technology for smartphones and other devices. Apple's Iphone is named as one of the infringing products, according to Loopinsight.

The 6271884 patent relates to image flicker reduction with fluorescent lighting, which works by setting the pixel integration time to an integral multiple of the periods between peak light intensity.

The 6838651 patent relates to a high sensitivity snap shot CMOS image sensor, made up of various pixels, analogue-to-digital converters and a colour interpolation circuit.

The 6838715 patent relates to CMOS image sensor arrangement with reduced pixel light shadowing, where the arrangement of pixels sees the first at the centre and the second on a peripheral edge.

The 7064768 patent relates to bad pixel correction while preserving features, which employs a dynamic range detection system.

Imperium Holdings claims that the seven companies mentioned have infringed upon its patents and wants an injunction granted to prevent them from shipping the allegedly infringing products. It also wants damages and will no doubt seek royalty licensing agreements with the companies. µ

One question : what does Imperial Holdings create ?

Because if they don't actually MAKE anything, then they have no right to complain that others do.
They should be thrown out of court on that basis.

Is this patent season for some reason?

Why are there so many patent lawsuit stories currently? Is there an escalating patent war going on? Is Company A sueing Company B and C because Company B is already sueing Company A, or because Company D is sueing Company B already and may bust them? (Company B possibly being Google's Android mobile device business.) Or does this start up annually so many days after the Superbowl, or what? Or, please, is it to do with a threat of patent reform, the nasty nasty government putting a stop to all this?

Here we go again...

Another company using another set of vague patents to sue all those around them.

And once again they sit silently on their so called patents for years before mentioning them and then start sueing.
