  AT-IP Report Rambus v. Infineon
Rambus’ construction of the disputed claim terms and its theory of infringement were directly at odds with the intrinsic evidence contained in specifications and prosecution histories of the patents-in-suit.
Rambus’ view of the patents was completely untethered to the language of the patent claims or the written description, and in many cases, flatly contradicted the written description.
Rambus’ WIPO application was discussed during JEDEC meetings, and Rambus claimed that, as a result, all its inventions were disclosed, and such disclosure put all relevant observers on notice that it was seeking patent protection in technological areas related to the SDRAM and DDR SDRAM industry standards under consideration.

  Rambus - Wikipedia, the free encyclopedia
Rambus Incorporated NASDAQ: RMBS (founded 1990) is a provider of high-speed interface technology, most notably their Rambus Direct RAM memory technology, which was intended to replace SDRAM and challenge DDR RAM as the standard memory used in computers.
Rambus had been trying to interest memory manufacturers in licensing their proprietary memory interface, and all companies had signed non-disclosure agreements to view Rambus' technical data.
Rambus was accused of shredding key documents prior to court hearings, the judge agreed and dismissed Rambus's case against Infineon.

 Court rules against Rambus | CNET News.com
Rambus sued Infineon, alleging that the German memory manufacturer owed it royalties on its output of SDRAM, the most common form of memory used in PCs, and DDR DRAM, a high-speed memory design gaining popularity.
Rambus executives, among others, have said the survival of the settlement agreements is contingent upon the patents being upheld by the court system.
Rambus, however, was hurt by evidence that indicated it tried to steer the memory committee toward technology standards that secretly favored it, McCarron said.

 USATODAY.com - FTC outlines appeal in Rambus patent case   (Site not responding. Last check: 2007-08-02)
SAN JOSE, Calif. — Computer chip designer Rambus could pocket up to $3 billion in royalties and raise prices for consumers of all manner of computing devices if an administrative law judge's ruling in its favor is allowed to stand, the Federal Trade Commission argued in an appeal.
The filing warns that any Rambus royalties collected by chip makers would ultimately be paid by consumers who buy personal computers, gadgets and a variety of other devices that rely on silicon-based memory.
In its June 2002 complaint, the FTC alleged Rambus failed to disclose a patent and applications that involved several technologies that were eventually adopted by a standards-setting group.

 Rambus, Inc. - Class Action Case C-01-3131 - Securities Class Action
Rambus' contention that its SDRAM patent goes back to the frequently withdrawn and continued claims appended to the 1990 application seems to be a prima facie admission the company failed to disclose such proprietary IP to JEDEC.
Rambus was now asserting that any chip manufacturer using technology that either provided or was designed to accept a connection based on synchronous memory technology was liable to the Company for royalties based on claims made in the Company's 1990 patent application.
Rambus vowed to appeal this ruling, however, analysts were quick to note that the loss of this decision could put a rapid end to Rambus' licensing royalty growth, which accounted for over 75% of the Company's revenues during the last two quarters.

 Rambus, Inc.
The Federal Trade Commission has charged Rambus, Inc., based in Los Altos, California, with violating federal antitrust laws by deliberately engaging in a pattern of anticompetitive acts and practices that served to deceive an industry-wide standard-setting organization, resulting in adverse effects on competition and consumers.
Had Rambus properly complied with JEDEC's rules and abstained from any misleading conduct, the FTC contends that this likely would have impacted the content of the organization's SDRAM standards, the terms on which Rambus could license any pertinent patent rights, or both.
That is, according to the FTC, the royalties that Rambus has been able to charge SDRAM manufacturers would not likely have been sustainable without the pattern of misleading and deceptive conduct outlined in the complaint.

 bit-tech.net | FTC finds Rambus guilty
According to the report, Rambus participated in JEDEC and (quite successfully) helped steer it to certain standards, and then used that information to secretly file patents on the technologies outlined.
JEDEC would approve a standard, and then Rambus would be the only one allowed to make it, unless other companies would pay it a hefty licensing fee.
Rambus has filed several suits in between the improprieties and this report, all against other RAM manufacturers for...you guessed it, patent infringement.

 Kingston Technology Rambus Memory Overview   (Site not responding. Last check: 2007-08-02)
Rambus memory technology is a proprietary memory technology invented by Rambus Inc. It was selected by Intel Corporation to power a new generation of high-performance PCs with increasing memory bandwidth requirements.
Rambus is considered to be a revolutionary memory technology, as opposed to evolutionary, when compared to SDRAM because it requires a totally new memory architecture.
Because all Rambus memory socket in a motherboard must be populated for the memory to work correctly, Continuity RIMM (C-RIMM) and Continuity Small-Outline RIMM (C-SORIMM) modules are required to maintain the continuity of the signals.

 AT-IP Report Rambus
Rambus claimed it could not be found to have failed to comply with JEDEC’s disclosure requirements because it did not file the applications which resulted in the SDRAM and DDR SDRAM patents at issue until after it had ended its membership in JEDEC Committee 42.3.
Rambus thus claimed it disclosed the entire body of its invention with the patent disclosure it did make and such disclosure put all relevant observers on notice that it was seeking patent protection in technological areas related to the SDRAM and DDR SDRAM industry standards under consideration.
Infineon claimed Rambus was required to disclose these predecessor pending patent applications, and pointed out that if it had done so, other participants in the standards setting process would have known Rambus was seeking patent coverage in areas of technology that may be implicated by the standard chosen.

 Rambus: It finally works! - Forbes.com   (Site not responding. Last check: 2007-08-02)
Rambus is one of a new breed of technology companies that makes no product, instead licensing its technology to others in exchange for royalty payments.
Rambus makes the technology known as Direct RDRAM, which allows the dynamic random access memory (DRAM) to communicate on an accelerated basis with the superfast microprocessors, thereby increasing the performance of those computers.
However, Rambus plans for global DRAM domination stopped on September 27 when Intel announced that it was delaying the release of its 820-chipset because flaws had been discovered in the chip's Rambus-based memory technology.

 FTC: Rambus Deceptive in DRAM
The FTC said Rambus deceived the technology industry by participating in the standards-setting process with the Joint Electron Device Engineering Council (JEDEC) without disclosing the company was developing patents that involved the specific technology ultimately approved by JEDEC.
Once the SDRAM standard was adopted, Rambus attempted to either collect on royalties or sue those companies that refused to comply, which included Infineon, Samsung, Hitachi, Hyundai, and Micron Technology.
He added that Rambus' conduct not only violated antitrust laws, but also constituted an unfair method of competition in violation of the broader reach of the FTC Act.

 Rambus was right all along, darn it
Rambus has also alleged that a conspiracy existed to prevent its RIMM modules from gaining the importance in the desktop market that they should.
The trouble was that Rambus' refusal to engage made the whole world see it as an arrogant little squit, and perception is more important than engineers and techies think.
Since then, Rambus has made strenuous efforts to engage with the marketplace and is happy to talk to journalists and to analysts.

 FTC Finds Rambus Unlawfully Obtained Monopoly Power
In June 2002, the FTC charged Rambus with violating federal antitrust laws by deliberately engaging in a pattern of anticompetitive acts to deceive an industry-wide standard-setting organization, which caused or threatened to cause substantial harm to competition and consumers.
“Rambus claims that the superiority of its patented technologies was responsible for their inclusion in JEDEC’s DRAM standards,” the opinion states.
Rambus now claims that we can and should blind ourselves to the link between its conduct and JEDEC’s adoption of the SDRAM and DDR SDRAM standards, as well as to the link between JEDEC’s standard-setting process and Rambus’s acquisition of monopoly power.
