Trademark Rights Protection: Official Lawyer's Letter Issued

In response to recent infringements in the market, our company has officially issued a lawyer's letter to carry out rights protection regarding the exclusive rights of the "GRAEFF" and "格拉夫" series trademarks.

Verified by the lawyer: the controlling shareholder of Graeff (Jiaxing) Instruments Co., Ltd. is Graeff (Shanghai) Technology Co., Ltd., which is a 100%-owned Chinese subsidiary of GRAEFF INSTRUMENTS LIMITED (UK). The "GRAEFF" and "格拉夫" series trademarks have been approved and registered in Class 9 by the Trademark Office of the State Administration for Industry and Commerce, and Graeff (Jiaxing) Instruments Co., Ltd. is the sole legitimate owner of these series trademarks within the territory of China.

Currently, certain websites and market channels engage in the unauthorized production and sale of products bearing the "GRAEFF" or "格拉夫" trademarks or similar marks. Such acts have constituted trademark infringement, which not only damages our company's brand value and business reputation, but may also constitute criminal offenses in serious cases.

Hereby, we solemnly declare

1.Cease infringement immediately — all unauthorized enterprises, individual businesses and individuals shall immediately stop the production and sale of goods bearing the "GRAEFF" and "格拉夫" series trademarks;

2.Obtain authorization for legitimate operation — entities interested in distributing GRAEFF products may contact our company directly to obtain formal authorization;

3.Report counterfeiting — customers who discover counterfeit goods bearing the "GRAEFF" and "格拉夫" trademarks may report to our company through official channels.

For entities that refuse to cease infringement, our company will, in accordance with the Trademark Law, Patent Law and Anti-Unfair Competition Law of the People's Republic of China and other relevant laws and regulations, take all necessary measures including administrative complaints and civil litigation to pursue full legal liability of manufacturers, distributors and relevant end users, with no leniency.

Opposing Malicious Smears and Protecting Brand Reputation

We always welcome fact-based feedback and suggestions from customers and are willing to respond to reasonable concerns with an open attitude. However, we will not tolerate deliberate rumor-mongering, malicious attacks and commercial defamation targeting our company on the Internet and through certain channels.

Such false statements seriously mislead public judgment, damage the brand reputation we have built over many years, and disrupt normal market order. Currently, our company has collected and preserved relevant evidence and entrusted a law firm to follow up on the matter. We solemnly advise the relevant parties to immediately delete false content and cease the publication and dissemination of false information. If defamation continues, our company will, in accordance with the Civil Code and Anti-Unfair Competition Law of the People's Republic of China and other relevant laws, pursue legal liability including public apology, elimination of adverse impact, and compensation for goodwill losses.

To Our Valued Customers and Partners

We call on friends from all sectors to exercise rational judgment, purchase products and verify information through official GRAEFF channels, and refrain from believing or spreading unverified content. If you encounter counterfeit products or discover false information, please feel free to contact us at any time.

GRAEFF will continue to uphold the philosophy of "customer first, integrity-based", deepen its expertise in pressure sensing technology, repay customer trust with higher-quality products and services, and work with partners from all sectors to maintain a healthy and fair market environment.
