Japanese professor sues Intel for infringing ALM patent on chips

Intel already has a few legal battles behind it, although large companies are usually involved. However, this time change the demandingand it’s a japanese teacher. According to him, Intel manufactured and sold fries FPGAs and SoCs that use adaptive logic modules (ALM), nail patent owned by the Japanese professor from 2004 to 2014.

A Japanese teacher named Masahiro Iida, sued Intel for infringement of U.S. Patent No. 6,812,737, accusing it of making, using and selling a patent it owned. It was ALM or Adaptive logic modules, used by Intel to improve the performance and efficiency of FPGAs (Field Programmable Gate Array). However, these were discovered by Iida, a long time ago.

With ALM, efficiency is improved and FPGA chip size is reduced

When Iida was a PhD student in 2001, he discovered a method for setting up large lookup tables (LUTs). It was that a LUT with M inputs and N outputs can work as a single “full” LUT or a group of “split” LUTs. Thanks to this union and this fragmentation, it has been possible to improve the consumption of energy and reduce the Cut tokens.

Shortly after the discovery, Iida filed a patent application first on June 29, 2001 and then on June 28, 2002. It was not until November 2, 2004 that the United States Patent and Trademark Office (USPTO) gave him the patent 737. This was titled as a “programmable logic circuit device that uses a LUT to reduce the implementation area”.

Thus, he was the sole owner from that same year 2004, until October 2014. However, the first dispute arose when Altera, a company in the fpgaused ALM in its chips Altera Stratix IIreleased the same 2004. Additionally, the company continued to use ALM in its later chips, such as Stratix III, Stratis IV That is Stratis V; In addition to products based on Arria Yes cyclone.

Intel bought out Altera and continued to market its chips with ALM, hence the request

This is when the reason for the request begins, and that is that Intel acquired amended in 2015 by $16.7 billionthe same way as amd purchased Xilinx for $54 billion This year. With the acquisition of this company, Intel continued to manufacture and market the Stratix, Arria and Cyclone ranges and chips. Agilexall with ALM.

According to the report, Intel would have obtained up to 80% of its annual revenue selling FPGAs and SoCs that use ALM. In fact, they are estimated at least $11.5 billion sales of these products from 2016 to 2022. As we can see, Intel is benefiting greatly from this sector, without having yet paid any financial compensation to the Japanese professor.

Therefore, Iida demands monetary compensation for this, equal to or greater than one royalty fee you should have received if Intel had licensed your patent. You are also asking the Court to award you up to three times the sum fixed by the jury to cover the offense of Intel and the costs of the lawyer.

Professor Iida’s attorney, for his part, sent a certified letter to Intel’s General Counsel regarding the infringement of the 737 patent. Intel, of course, continued to manufacture and sell FPGA chips and SoCs without the Licence of ALM, although that may change with this request.
