According to reports, Mars Foods (China) Co., Ltd. investigated and found that Guangdong Shangxun Company used "Mars" and "MARS" for publicity when participating in the "Second Asia Pet Aquarium Expo 2015", and publicized and reported on the trademarks of "Mars" and "MARS" on the official website of the Asia Pet Aquarium Expo. Not only that, Guangzhou Shangxun also sells pet foods that use the trademarks "Mars" and "MARS" in its Taobao stores, and uses "Mars" and "MARS" for publicity. For this reason, Mars sued Guangdong Shangxun Company to the Guangzhou Intellectual Property Institute on the grounds of trademark infringement and unfair competition.

After the trial, the Guangzhou Intellectual Property Institute ruled that Guangdong Shangxun immediately stop using and promoting the "Mars" and "MARS" trademarks and unfair competition, and publish a statement in the "China Intellectual Property News" to eliminate the impact and compensate Mars Foods (China) ) Co., Ltd. economic losses and reasonable expenses totaling 400,000 yuan.
