How RheinPro GmbH Won Back Its Chinese Trademark: A Mid-Size Foreign Firm’s Case Study
When German industrial sensor maker RheinPro GmbH entered China in 2019, it discovered that a local trading company had already registered its logo and company name as a 商标 (trademark, shāngbiāo). The battle to reclaim its own brand cost the mid-size firm ¥2.3 million in legal fees and lost 14 months of market traction—yet the outcome transformed its China strategy. This case study examines how a foreign firm with 120 employees and €18 million in annual revenue navigated China’s trademark enforcement system, from emergency cancellation petitions to CNIPA hearings, and what other mid-size exporters can learn from the process.
Background: The China Entry That Nearly Failed
RheinPro GmbH, headquartered in Stuttgart, manufactures precision industrial sensors for automation lines. By 2018, the company had distributors in Southeast Asia and the Middle East, but China—its fastest-growing export market—remained untapped. The firm hired a Shanghai-based consultant and filed a 商标注册 (trademark registration, shāngbiāo zhùcè) application in March 2019 under Class 9 (scientific instruments).
To its shock, CNIPA (国家知识产权局, guójiā zhīshì chǎnquán jú) rejected the application in June 2019, citing an identical mark filed in January 2018 by a Shenzhen trading company, Huafeng Commerce. Huafeng had no manufacturing operations and no relationship to RheinPro. The mark was a near-exact copy of RheinPro’s German logo—a stylized “RP” inside a gear—and the company name “RheinPro” was similarly registered under Class 35 (advertising and business services).
RheinPro faced an impossible choice: abandon the Chinese market, pay Huafeng an undetermined license fee, or fight. By September 2019, the firm had lost an estimated RMB 500,000 in pending orders from Chinese OEM buyers who refused to sign without a clear trademark position. The clock was running, and the annual China Sensor Expo was only six months away.
The Legal Battle: Cancellation and Opposition
RheinPro’s legal team, led by a Beijing IP firm, pursued a three-pronged strategy. First, they filed a 恶意抢注 (bad-faith registration, èyì qiǎngzhù) cancellation petition with CNIPA’s Trademark Review and Adjudication Board (TRAB) in October 2019. The evidence package included Huafeng’s public business registry showing zero manufacturing assets, RheinPro’s prior international trademark filings dating to 2015, and proof of pre-existing commercial relationships between Huafeng’s director and a former RheinPro distributor in Guangzhou.
Second, they filed an opposition against Huafeng’s pending Class 35 application for “RheinPro.” Third, they registered defensive marks for RheinPro’s product series—e.g., “RheinSens” and “RheinFlow”—to block further squatting. The total cost for legal retainer, translation, notarization, and CNIPA filing fees reached ¥1.8 million by the end of 2019, with additional expenses for a private investigator who documented Huafeng’s empty office.
In March 2020, TRAB ruled in RheinPro’s favor, canceling Huafeng’s Class 9 mark on grounds of bad faith. Huafeng appealed to the Beijing Intellectual Property Court, dragging the case into 2021. The court upheld the cancellation in April 2021, and RheinPro’s own trademark was approved by August 2021—32 months after the first application. By then, the firm had spent a total of ¥2.3 million on the dispute, including the cost of a Chinese-language brand investigation and expedited publication fees.
Numbers That Shaped the Strategy
Throughout the process, four numbers guided every decision. 47% of foreign firms entering China encounter trademark squatting, according to a 2023 European Chamber of Commerce survey—meaning RheinPro’s situation was not exceptional but predictable. 14 months elapsed between the cancellation filing and the final court ruling, during which RheinPro could not legally sell under its own name. ¥2.3 million represented 8% of the firm’s annual China revenue target, but the legal team calculated that license fees would have exceeded ¥5 million over three years if Huafeng had demanded royalties. Finally, 3,200 is the number of trademark squatting cases CNIPA handles annually—a figure that has grown 18% year-over-year since 2020, making proactive registration the only sustainable defense.
RheinPro’s CEO later remarked that the company should have filed its Chinese trademark in 2016, when it first began exporting to Asia. The delay cost the firm not only money but also trust with early Chinese distributors who had to wait two years for a clear brand position.
Decision Framework for Mid-Size Foreign Firms
Based on RheinPro’s experience, the trademark entry decision breaks into two paths:
- If your company has a distinctive logo and a market-ready product but no China trademark history: choose the “File Before You Ship” strategy. Register your mark in China at least 12 months before your first distributor agreement, covering Classes 9, 35, 42, and any product-specific classes. This minimizes squatting risk and avoids the cancellation battle RheinPro endured.
- If your trademark is already squatted by an unrelated third party: choose the “Prove Bad Faith” path. Assemble evidence of prior use, international registrations, and the squatter’s lack of legitimate business activity; file a TRAB cancellation petition within 24 months of discovering the squatting. This route costs ¥1–3 million and takes 12–24 months, but it is the only way to regain ownership without paying a license.
RheinPro fell into the second category. The decision was not optional—without the trademark, the Chinese market was closed.

Pitfalls RheinPro Encountered
Lessons Learned and Post-Case Positioning
After the trademark was secured in August 2021, RheinPro opened a WFOE (外商独资企业, wàishāng dúzī qǐyè) in Shanghai to directly manage brand licensing and distributor contracts. The company now holds 8 registered trademarks in China, including its logo, company name, and three product series. At the 2022 China Sensor Expo, RheinPro displayed its brand with confidence and signed RMB 12 million in new orders—its first profitable China year. The legal battle, while painful, gave the firm a clear understanding of CNIPA timelines and the importance of a Chinese-language brand architecture.
One specific tactic that proved valuable was the use of a 商标共存协议 (trademark coexistence agreement, shāngbiāo gòngcún xiéyì) with a small Chinese firm that owned a similar mark for “RheinPro” under Class 7 (machinery). Instead of fighting, RheinPro negotiated a limited coexistence agreement that allowed both parties to operate in non-overlapping classes. This saved an estimated ¥800,000 in potential additional litigation costs and avoided further delays.
For mid-size foreign firms, the takeaway is straightforward: China’s trademark system is first-to-file, not first-to-use. Registering early is not optional—it is the single most important pre-market investment you can make. RheinPro’s 32-month ordeal could have been avoided with a ¥7,800 filing five years earlier.
NEXT STEPS
- Run a CNIPA trademark search now. Before you engage any Chinese distributor, search your brand name and logo on CNIPA’s public database. If a conflict appears, file a preemptive opposition or negotiation. Read our guide: China Trademark Search Checklist for Foreign Firms.
- File a defensive class basket. Register your mark in Classes 9, 35, 42, and one supply-chain-related class. Use an international application under the Madrid Protocol to leverage priority from your home filing. See the step-by-step process: How to File a China Trademark via the Madrid System.
- If your trademark is already squatted, start a bad-faith evidence package. Collect your international registration certificate, proof of prior commercial relationships in China, and the squatter’s business registry. File a TRAB cancellation petition within 24 months of discovery. Learn the evidence requirements: Building a Bad-Faith Case for Trademark Cancellation in China.
