Chang Tsi & Partners was recently honored to welcome representatives from Lei Yunshang Group, who visited the firm to present an honorary plaque in recognition of Chang Tsi’s professional legal services and successful representation in a landmark trademark recognition matter. The plaque bears the inscription: “Professional Excellence Driving Brand Development”, reflecting the client’s appreciation for Chang Tsi’s expertise, efficiency, and commitment throughout the process.

Securing Enhanced Protection for a Historic Chinese Brand

Founded in 1734, Lei Yunshang is one of China’s most respected and enduring pharmaceutical brands. With a history spanning nearly three centuries, the company has built a strong reputation for traditional Chinese medicine, quality craftsmanship, and consumer trust. As a renowned China Time-Honored Brand, the value of the “Lei Yunshang” name extends far beyond a trademark—it represents generations of heritage, innovation, and goodwill.

Recently, through the representation of Chang Tsi & Partners, the China National Intellectual Property Administration (CNIPA) officially reaffirmed the well-known trademark status of Lei Yunshang’s core trademark, No. 560667 “雷允上及图” (Lei Yunshang & Device), granting it enhanced legal protection under Chinese trademark law. This recognition provides stronger protection against unauthorized use and imitation, further reinforcing the legal foundation for safeguarding the brand’s reputation and market position.

Combining Legal Expertise with Strategic Brand Protection

In today’s increasingly competitive marketplace, well-known brands face growing challenges from trademark infringement, unfair competition, and attempts to capitalize on established brand reputations. For long-standing enterprises such as Lei Yunshang, protecting brand assets is not merely a legal matter—it is a critical component of preserving corporate heritage and maintaining long-term business value.

Leveraging its extensive experience in trademark protection and intellectual property enforcement, Chang Tsi & Partners provided comprehensive support throughout the recognition process. The legal team worked closely with the client on evidence collection, legal analysis, strategic planning, and procedural management, ensuring that every aspect of the application met the stringent requirements for well-known trademark recognition.

The successful outcome reflects not only the strength and recognition of the Lei Yunshang brand itself, but also Chang Tsi’s ability to deliver practical, efficient, and results-oriented legal solutions for clients facing complex IP challenges.

A Recognition Built on Trust and Partnership

The presentation of the honorary plaque represents more than a successful legal result—it symbolizes the trust and long-term partnership between Chang Tsi & Partners and Lei Yunshang Group. For the firm, client recognition remains one of the most meaningful measures of professional achievement. It reinforces Chang Tsi’s commitment to delivering high-quality legal services and creating tangible value for clients through effective intellectual property strategies.
