Liseng IP Attorneys helped Midea Group in invalidating SEB's patent asserted for Patent Infringement

In recent years, with the strong rise of innovative companies, traditional companies have often resorted to patent infringement lawsuits to try to counter it. It is also in this context that SEB filed an infringement lawsuit against Midea, the white appliance manufacturing giant, in the Guangzhou Intellectual Property Court.

 

In this competitive environment, LISENG accepted the entrustment of the client, Guangdong Midea Life Electrical Appliance Manufacturing Co., Ltd., and filed a patent invalidation against the patent involved in the lawsuit (ZL201380005609.1). And all the claims in the patent involved that are risky to our customers are invalidated, and directly led to the loss of SEB in the first instance, successfully safeguarding the legitimate rights and interests of our customers.

 

Introduction to the case

 

In July 2021, our company was entrusted by the client, Guangdong Midea Life Electrical Appliance Manufacturing Co., Ltd., to invalidate the invention patent ZL201380005609.1 of SEB company. This case is a essential technology developed by SEB in 2013, and the priority date is February 16, 2012.

 

After LISENG undertook this case and after the preliminary analysis, the cooking method and device were difficult to search for evidence because they were control method patents and the technology involved in the field of daily life. Through repeated discussions by the intellectual property team of the client Midea Life Electrical Appliance, research journals and oversea patents were finally determined as the key search databases, and based on the evidence "American Society of Animal Science: Identification of optimal ranges in ribeye area for portion cutting of beef  steaks" and US patent application US20060254430A1, SEB patent was successfully invalidated.

 

In this case, the invention patent is an international patent entering China, due to the poor translation of the technical solution, resulting in unclear technical solution, our invalidation team after repeatedly confirming the possibility of understanding the claim with the Midea team, we drafted and submitted a professional invalidation request to PRB.

 

Typical significance

 

For patent invalidation, a high degree of collaboration with the client's intellectual property team and R&D team is very important to carry out an effective invalidation action, and in the process of invalidation for this case, Midea Group played a very key role in the presentation and execution of the search and invalidation strategy to the final success of our invalidation team.

 

In important patent cases, our company can continue to obtain a high degree of recognition from customers and the cornerstone of business entrustment, which is also an important working principle that our company has adhered to since its establishment.

 

In addition, in the process of international patent application delegation, international application is not a simple process of translating from English to Chinese, and improper translation may lead to disastrous consequences.
