History
"Wong Lo Kat" is the Cantonese transliteration of its name in Chinese characters. Wong Lo Kat originated in 1828 during the Qing Dynasty in Guangdong (Kwangtung) and Guangxi (Kwangsi) provinces of China, founded by a doctor Wong Chat Bong. Because the Wong family was the inventor of herbal tea brewing in southern China, the brand is synonymous with this type of drink. The recipe has been passed down through multiple generations to today's tea culture.

In around 1949, the Chinese government began seizing private companies and all associated assets. Wong Lo Kat's descendants established operations in Hong Kong, whilst all assets in Mainland China passed to a government-owned subsidiary.

Trademark dispute in Mainland China
After the foundation of the People's Republic of China, Wong Lo Kat (pronounced in Mandarin) in mainland China has been owned by the government.

"Wanglaoji"'s trademark right holder, Guangzhou Yangcheng Pharmaceutical (广州羊城药业), whose name was later changed to "Guangzhou Wanglaoji Pharmaceutical Co., Ltd." (广州王老吉药业有限公司), a subsidiary of the state-owned Guangzhou Pharmaceutical Holdings Limited (广州医药集团有限公司), licensed the right to use the 王老吉 trade mark to Hong Kong Hung To Group Co., Ltd. (香港鴻道集團有限公司), who marketed the Wong Lo Kat product in red cans, meanwhile the 250 ml green carton version has been produced by Guangzhou Pharmaceutical themselves.

In 1997, Hung To Group and Guangzhou Pharmaceutical signed a trademark license agreement. Hung To Group had legally gained the right to use 王老吉 and, its subsidiary, JDB Beverage Co., Ltd. (加多宝饮料有限公司; aka. ) had been the producer of the red can version of Wong Lo Kat in mainland China. JDB Group also used the traditional English name Wong Lo Kat in mainland China, which is the 王老吉 in Cantonese spelling since 1828.

The trademark license was renewed in 2000 to make it valid until 2 May 2010. In 2002 and 2003, two additional extensions were signed, extending the validity to 2013 and 2020 respectively.

The sales by JDB increased more rapidly than by Guangzhou Pharmaceutical. The sales of the red can version was at more than 1 billion RMB while the green carton version had annual sales of estimated 80 million RMB in 2004. In 2008, the red can's sales exceeded 10 billion RMB, its annual sales volume in 2007, 2008 and 2009 topped in Chinese beverage can products.

Guangzhou Pharmaceutical Holdings' general manager Li Yiming (李益民) was found guilty of fraud in 2005. As part of the agreements to extend the license, he accepted payment of 3 million HK dollar's from Hung To Group's Chan Hung To (陳鴻道). Hung To Group states that they considered the payment a legitimate fee in relation to the license agreement extension, however, in light of Li Yiming's known fraudulent activity, and as the funds were never received by Guangzhou Pharmaceutical the payment was officially declared a bribe.

In April 2011, Guangzhou Pharmaceutical submitted a "Wanglaoji" trademark issue for arbitration. On 9 May 2012, China International Economic and Trade Arbitration Commission ruled that the two additional trademark contracts were invalid, the valid trademark agreement had expired on 2 May 2010, thus Hung To Group and JDB had no right to use "Wanglaoji" trademark after that date.

Since 2011, it had been explicitly printed "produced by JDB" on red can products. The product's name has been completely changed to "JDB" (加多寶; aka. ) since May 2012.

Several days after the arbitration, Guangzhou Pharmaceutical started to produce their own red can Wanglaoji beverage.

Wong Chat Bong's descendant in Hong Kong, Wang Jianyi (王健仪), who operated Wong Lo Kat's entity outside the mainland, expressed her support for JDB company.
