The article you posted is about the lawsuit between Tsuburaya and the 'Tobacco and Tang' company. It is a lawsuit between the copyright owner and the non-piracy copyright owner of the seller.

lisense by ruishi is a pirated version. As for the lawsuit between Ruishi and Tsuburaya you mentioned, I will try my best to explain it to you clearly.

In the past, there was a Thai man named Simbote Santenchai. He had collaborated with Tsuburaya on special photography films before, but in 1976, he used unconventional means to acquire the film from the former Tsuburaya. Acquired Ultra Q from the Showa era, Ultra Seven, Ultra Jack, also known as the returning Ultraman Ace, Ultraman Taro, and Hanuman and Hanuman from his own film company chaiyo productions. The exclusive overseas copyright of Ultraman Seven Ultraman. This refers to the copyright of Ultraman outside of Japan. The details can be seen in the infamous 1976 contract, which first authorized these fake copyrights to Sharp Vision, and then there were Ultraman peripherals with such inscriptions, and then Tsuburaya saw them, and it started for six years and three games. Of the three lawsuits, Tsuburaya only won once. In the end, Tsuburaya lost the lawsuit, which also proved that after this fake copyright contract was valid in my country and the United States for a few years, Thailand's fake copyright was invalid, because Tsuburaya After winning the lawsuit against Simbert, Ruishi's copyright became invalid in 2018, but they are still producing toys related to Ultraman. To this day, there is still a lot of controversy in China whether this contract is valid.

The above are my questions and answers after researching your question. Since this is my first answer, if I make any mistakes, subsequent questioners are welcome to correct my mistakes.
