Rambus won important findings in a U.S. International Trade Commission (ITC) patent case against Nvidia, but it did not secure a lasting ban on Nvidia products. The case created leverage over certain products containing memory controllers; the companies first announced a controller license and later settled their remaining claims through a broader, five-year patent license. The public announcement of that later deal did not disclose its financial terms.
What Rambus won—and what it did not
The ITC dispute was about whether specified Nvidia products infringed Rambus patents, and whether imports of infringing products should be excluded from the United States. It was not a court award of damages for every Nvidia product, nor a finding that all Nvidia products infringed.
Rambus filed its complaint on November 6, 2008. It accused products incorporating memory controllers, including graphics processors, application processors, media and communications processors, and chipsets. The complaint asserted nine patents; Rambus later withdrew four.
On January 22, 2010, the ITC administrative-law judge (ALJ) found three of the five remaining patents valid, enforceable and infringed. The judge found no Section 337 violation for the other two. That is a significant but bounded result: three patents prevailed in the ALJ’s analysis, not all nine patents or every product in the accused categories.

How the ITC remedy worked
In July 2010, the Commission affirmed the ALJ’s findings with modifications and said it intended to issue a limited exclusion order covering infringing products, along with cease-and-desist orders for identified respondents. An exclusion order is an import remedy; it is not a damages award. “Limited” matters: the order was aimed at covered infringing products, not Nvidia’s entire product line.
The Commission allowed imports and sales during the 60-day presidential review period if respondents posted a bond equal to 2.65% of the entered value. That temporary bond requirement could raise the cost of continuing to import covered products while the review proceeded. It did not itself establish a final royalty rate or a payment owed to Rambus.

How the dispute moved from an import remedy to licensing
| Date | Development | What it meant |
|---|---|---|
| November 6, 2008 | Rambus filed its ITC complaint, initially asserting nine patents. | The complaint sought an exclusion order against specified Nvidia products alleged to use infringing memory controllers. |
| January 22, 2010 | The ALJ found three of five remaining patents valid, enforceable and infringed; the other two did not establish a Section 337 violation. | Rambus gained favorable findings, but only on part of its case. |
| July 26, 2010 | The Commission affirmed with modifications and intended to issue a limited exclusion order and cease-and-desist orders. | Covered products faced potential import restrictions, subject to the review period and its bond condition. |
| August 13, 2010 | The companies announced a memory-controller license. | The published schedule set royalties for specified controller types; the announcement said releases and dismissals of outstanding litigation had not yet been signed. |
| February 8, 2012 | Rambus announced a broader five-year patent-license agreement with Nvidia. | The agreement covered a wide range of Nvidia integrated-circuit products and settled all outstanding claims; financial terms were confidential. |
The initial 2010 license announcement published rates of 1% for SDR memory controllers and 2% for other listed controllers: DDR, DDR2, DDR3, LPDDR, LPDDR2, GDDR2, GDDR3, GDDR4 and portions of GDDR5. Those are rates from that announced schedule, not disclosed terms for every product under the later agreement.
The 2010 announcement also said the parties had not yet signed releases or dismissed outstanding litigation. The 2012 announcement marked a broader settlement: it described a five-year license covering a wide range of Nvidia integrated-circuit products and said all outstanding claims were settled. It did not publish Nvidia’s total payments, minimum guarantees or later per-product rates, so a total settlement amount cannot be stated from the public terms described in that announcement.
Could Rambus ban Nvidia products?
The ITC process put an import restriction on the table for products found to infringe, but the record described here does not establish a permanent, company-wide Nvidia ban. In July 2010, the Commission said it intended to issue a limited exclusion order covering infringing products. The parties then pursued licensing, and their 2012 agreement settled the outstanding claims.
For customers, the practical distinction is between a legal threat and the outcome of the dispute. The potential remedy could have affected imports of covered products; the commercial endpoint publicly announced by the parties was licensing and settlement, rather than a lasting consumer-product prohibition.

Why the case matters beyond Nvidia
Patent findings can create negotiating leverage
A favorable infringement finding matters even when a case ends in a license instead of a product ban. In this dispute, the prospect of an exclusion order—and the bond condition during the presidential review period—gave the import issue practical weight. A license could resolve that risk while allowing the companies to continue their commercial relationship.
Licensing is different from winning damages
Rambus’s published 2010 controller rates illustrate how a patent dispute can translate into a royalty arrangement. They should not be confused with damages awarded by a court or with the undisclosed financial terms of the 2012 agreement. The ITC findings and the parties’ private license deal are separate parts of the story.

Rambus’s business is built around intellectual property
Rambus’s 2025 Form 10-K describes its business as licensing patented memory, interface and security inventions to semiconductor companies, including Nvidia. It reported 2,049 U.S. and foreign patents as of December 31, 2025. That context helps explain why licensing outcomes matter to the company, but the patent count is not a measure of the patents asserted or upheld in the Nvidia case.
Do not confuse this case with Rambus’s FTC matter
The FTC’s Rambus matter involved allegations of deception in JEDEC standard-setting and four DRAM technology markets. It is separate from the Nvidia ITC investigation, which concerned alleged patent infringement by products containing memory controllers. The FTC controversy is background to Rambus’s broader patent history, not the holding in the Nvidia case.
