Siliwei's counterattack: huiding's under screen optical fingerprint patent involved in the case was declared invalid

In recent days, , According to the information released by the State Intellectual Property Office , Shanghai Sili Microelectronics Technology Co., Ltd （ hereinafter referred to as “ Siliwei ”）, For Shenzhen huiding Technology Co., Ltd （ hereinafter referred to as “ Huiding ”） The patent application number of is 201821077979.2 Of “ Off screen biometric devices and electronic devices ” Patents , The request for invalidation was approved by the State Intellectual Property Office .

It also means that , The application number previously owned by huiding is 201821077979.2 Of “ Off screen biometric devices and electronic devices ” All the patents of are invalid , Therefore, siliwei does not infringe the patent of huiding . And this will also affect last year 11 The follow-up trend of yuehuiding suing siliwei for infringement has a great impact .

Huiding sued siliwei for infringing three patents , One of them was declared invalid

2018 year 11 month 2 Japan , Huiding technology sued siliwei for infringement of its 3 Item patent , Respectively 1 Biometric recognition device under the item screen 、 Biometric components and terminal equipment patents , as well as 2 Patents for off screen biometric devices and electronic devices , Specific patents are applied to off screen optical fingerprint products , And to put forward 1.5 Compensation of 100 million yuan and requirements for destroying inventory . The key of these three patents is that the patent application number is 201821077979.2 Of “ Off screen biometric devices and electronic devices ” Patents .

Information from the State Intellectual Property Office shows , The patent application date is 2018 year 7 month 6 Japan , The applicant is huiding Technology , Patent application No 201821077979.2, The specific summary is ：“ The invention provides an off screen biometric recognition device and an electronic device , The off screen biometric recognition device comprises ： The lens , Set at the bottom of the display , It is used to receive the optical signal formed by the reflection of human fingers from the top of the display screen , The optical signal is used to detect the biometric information of the finger ; Barrel , The lens is fixed in the lens barrel ; Bracket , The bracket and the lens barrel are connected by threaded connection , The bracket is used to support the lens barrel . The off screen biometric recognition device and electronic device provided by the embodiment of the application , It can improve the efficiency of off screen biometric recognition .”

Siliwei responded at that time , The patent application number alleged by huiding technology is 201821077979.2 Of “ Off screen biometric devices and electronic devices ” Utility model patent , It involves the whole off screen fingerprint module . This plan is also CIS（ image sensor ） Standard design idioms in the field , Just changed to the scene of off screen fingerprint application . Therefore, siliwei has not applied for a patent on related technologies .

meanwhile , Siliwei also said , The utility model patent alleged by huiding technology is siliwei 2018 year 5 In September, we will design the structure of the above module with our partners , Its customers 2018 year 6 Mass production of fingerprint modules with complete structure began in August .

According to the data , The application time of huiding technology for this patent is 2018 year 7 month 6 Japan , And soon 3 Less than a month. ,10 month 30 I got the authorization on the th ,11 In September, he filed a lawsuit against siliwei . This time point is really very fast .

And then , Think about the future 2019 year 1 month 8 Filed an invalid application for the patent with the State Intellectual Property Office .

2019 year 8 month 7 Japan , The State Intellectual Property Office announced after hearing , The patent application number of huiding technology is 201821077979.2 Of “ Off screen biometric devices and electronic devices ” All utility model patents of are invalid . The legal basis is “ Article of the Patent Law 22 Article 3 paragraph ”, That is, compared with the existing technology , There are no prominent substantive features and significant progress .

Siliwei is expected to win a city , The entanglement between the two sides will continue

With the patent application number of huiding technology is 201821077979.2 Of “ Off screen biometric devices and electronic devices ” The utility model patent of was declared null and void , So it also means , last year 11 Yuehuiding technology sued siliwei for three patent infringement , One of them no longer exists . This will also have a great impact on the follow-up trend of this case .

in addition , Siliwei also filed invalid applications for two other patents . According to the data , The other two patents of huiding are based on the patent application No 201821077979.2 Of “ Off screen biometric devices and electronic devices ” A branch of utility model patents , As the main patent was declared invalid , Whether the other two patents continue to be valid has also become at stake .

If these three patents of huiding technology are declared invalid , No doubt about that. , The summit was last year 11 Three patent infringement lawsuits launched against siliwei in May may lose .

however , even so , The competition between the two sides is still inextricable , Huiding was last year 9 End of month , A capacitive fingerprint product manufactured and sold by siliwei and Dingxin was also prosecuted for infringing three patents, including its practical new type and invention , And claim RMB 2.1 Billion yuan and the reasonable expenses incurred by huiding to stop the infringement 150 Ten thousand yuan .

Regarding this , At that time, Sili micro sent a statement and responded that ,“ The three patents involved in the lawsuit belong to information processing circuit design 、 Packaging and terminal system implementation , They are all very common technologies in the industry . Before the application date of these three patents , Relevant technologies have been found in many public documents and applied to many public products .” Siliwei believes that the three patents do not conform to creativity 、 Novelty requirements , And plans to declare its application invalid .

in addition , Siliwei then fought back . And last year 12 month , Siliwei sued huiding , Said to be produced by huiding GF3258 Chip and mobile phones equipped with this chip sold by meizhizu , It has infringed three invention patents of siliwei , Ask huiding and meizhizu to stop infringement 、 Destroy all inventory infringing products , And the total compensation for economic losses is about 2.4 Billion .

At present, two infringement cases of huiding suing siliwei and the infringement case of siliwei suing huiding are under trial . What are the specific follow-up results , We will continue to focus on . however , With the explosive growth of the off screen fingerprint market , As the leader and the second in the market , Patent litigation between the two sides is only a means of market competition , The future handshake and peace are unknown .
