Rambus sues Nvidia for patent infringement

Rambus is suing Nvidia, accusing the company of violating 17 Rambus-held patents on memory controllers. The suit was filed Thursday in the U.S. District Court for the Northern District of California.

The Los Altos, Calif.-based company says that chipsets, graphics processers, and media communication processors across six different Nvidia product lines are illegally infringing. The patents held concern memory controllers for SDR, DDR, DDR2, DDR3, GDDR, and GDDR3 SDRAM.

Rambus is asking the court for an injunction (which would stop Nvidia from selling the products at issue), as well as monetary damages.

In a prepared statement, Rambus' head legal counsel, Tom Lavelle, said that Rambus has been attempting to get Nvidia to purchase a license for the patents, and the suit was the last resort. However, he said, Rambus hopes to settle the issue out of court.

CNET News is waiting to hear back from Nvidia for comment.

Yeah, settle it out of court..... those are words that only a patent troll uses. Frankly, NVidia should tell Rambus to stick it, and to go to court. This is a case where Rambus is not making ANY products that I know of using their technology that is in the same market as NVidia, so there is no reason for them to be filing this patent suit.

Rambus hires very expensive engineers to develop revolutionary technologies. For that, they expect to be paid royalties. Don't they have a right to that? I don't know how it follows that because you invent something, you must necessarily produce it too! After all, Thomas Edison invented a lot of things, but as far as I know, he never produced anything. Does that mean his inventions have no meaning and no worth???

Erica,

Someone in the media is going to invest the time to educate themselves and then write a great expose series about the truth here. It will be easy to do because they'd only need to read transcripts of sworn testimony, trial and appelate decisions.

The story would include very unusual proceedings in the Federal Court in Richmond, VA, the FTC (what's new?), and the US DOJ Micron Amnesty Agreement.

It's absurd. There are no stones to turn 'cause it's all in the record!

Get your Pulitzer and expose the bastard liars who've been stealing Rambus IP for over 10 years.

When will we get memory and memory controllers that Rambus does NOT have or believe they have patents on? Maybe they should ask for lower fees, but then what would they do with all the lawyers on retainer?

Rambus? Who the hell are they?

It looks like they turned into patent trolls since Intel dropped them like the losers they are.

"Rambus? Who the hell are they?" "like the losers they are"

yes they turned into patent trolls, but you need to do much more research before you can say that. their first and lowest performance rd module can still beat the crap out of the best ddr module out there.. even at half capacity. and the reason intel dropped them is because they didn't release new products, and who can blame them, still looking at the poor performance ddr chips out there apparently there was no point to do so. intel made a financial call not a performance-wise decision. just like the idiots at apple dropping ibm processors (u can't imagine how pissed i am cuz of that).

Rambus had its change 8 years ago when Intel married them. Poor performance, high cost and low yields sealed their fate.

Agree with you Murdo. Rambus can take the lawsuit all the way to the Supremes. They may lose, but they can sue. And no, they aren't SCO with trumped-up patents. Anyone remember when Nvdia made only video cards? I'm also pissed that Apple droped Power PC chips. They were much stronger tan the present Intel offerings. Don't believe me, buy a Lenovo laptop with IBM chips. No more Apple products for me unless I can get Power PC chips.

Nvidia is an intellectual property owner, just like Rambus. Nvidia licenses its patents to manufacturers, just like Rambus. It is hypocritical for Nvidia and its supporters to say that Nvidia should be paid by companies that use its patents but that Rambus should not be paid by companies that use its patents. It is fortunate for Rambus that patent infringement cases are generally not decided by anonymous and ignorant posters on the web who have nothing more to contribute than a negative attitude and name calling. Unlike Nvidia, Rambus has foundational patents for high speed signaling that are essential to all computer systems today.

I don't understand why bad News here? I have Memory RAM DDR2 + SDRAM and I have 3 Nvidia 5600 FX with 256 MB, 6800 with 256 MB, and 9800GX2 with 1 GB. My two Nvidia 6800 and 9800GX2 come with GDDR3. That is safe? or not? I need to know more please!!! If video card recall or need change to ATI video card for more safe reason? I need more deep info. I don't have problems with my all Nvidia so far!
