Recently, a news from the Patent Reexamination Board of the State Intellectual Property Office has attracted many people’s attention. The news mentioned the invalid application of its 201110240931.5 (a patent on FinFET) of Shenli. The invalid application was filed by Intel company, and the patentee was the Institute of microelectronics, Chinese Academy of Sciences.
In addition to the patent application filed by Intel and the United States in 2018, Intel and the United States have launched a patent infringement lawsuit, which is invalid for the last time in the past five years.
According to the information collected, the lawsuit content of the Institute of microelectronics is that “Intel Core series processor infringed its FinFET patent entitled” semiconductor device structure and its manufacturing method, and semiconductor fin manufacturing method “, requiring Intel to stop the infringement, compensate at least 200 million yuan for the loss, and bear the court litigation costs The court applied for an injunction.
Although China has been criticized by many domestic netizens in the field of microelectronics, our microelectronics strength is actually the strongest in the world except the United States. The Institute of microelectronics, which initiated the lawsuit, has very strong patent strength in the field of FinFET. In an evaluation in 20125, the number of patent applications ranked 11th, but the quality of patent applications ranked first in the world.
Up to now, the Institute has submitted more than 5000 Chinese patent applications, more than 500 foreign patent applications, 158 transferred patents and 1505 patent licenses in the fields of integrated circuits, highly reliable devices and circuits, and Internet of things. In fact, Intel is only one of the infringement companies. Before that, the Institute of microelectronics has launched a lawsuit against a number of infringement companies. With the enhancement of our strength in the field of microelectronics, it is estimated that there will be no less similar lawsuits in the future.
