Some of the most popular products from Apple Inc. (AAPL), Sony Corp. (SNE) and Nintendo Co. Ltd. (NTDOY) are the target of a new patent infringement lawsuit.

Shared Memory Graphics LLC, based in Newport Beach, Calif., alleges Apple iPods and iPod Touch music and video players, Nintendo's motion-controlled Wii and Sony PSP and PS2 game consoles uses two graphic accelerator systems patented by the company.

The two patents describe ways in which microprocessors fine-tune graphics by balancing the flow of data from various sources.

Apple had no comment on the lawsuit filed late last week in a U.S. District Court in Arkansas. Nintendo and Sony didn't immediately reply to requests for comment.

The patents were originally owned by Alliance Semiconductor Corp., which was founded in 1985, and became "renowned worldwide" for making faster memory and graphics semiconductors for computers, according to the lawsuit. At one time, the filing states, Alliance had 144 employees, and generated tens of millions of dollars in net revenue.

But after several years of substantial operating losses, the company in 2005 transitioned to a holding company, and ultimately sold the patents to what is now Shared Memory Graphics.

The litigation targets several high profile products. Nintendo's Wii, even though sales are slowing from their initial hectic pace, continues to a leading seller. Apple's iPod Touch, combined with the iPhone, are both major profit and revenue drivers at Apple. The same can be said for Sony's PS2 and PSP game consoles.

Apple shares were down 1%, to $138.61, on Monday. Sony was up 0.3%, to $25.27, and Nintendo added 0.9% to $34.40.
