GFCI products are safety equipment enforced by the US government to protect the personal safety of residents. There are five manufacturers in the world, representing the most advanced leakage protection technology in the world today. The GFCI products produced by four American enterprises all adopt the traditional electromechanical integrated leakage protection technology, and the GFCI products developed and produced by our company are the only patented technology independently invented in the world, namely, the automatic leakage protection technology based on the principle of zero-power permanent magnet electromagnetic tripping and electromagnetic resetting, which greatly improves the safety and detection sensitivity of the products and completely meets and exceeds the latest standard of UL943 of the National Security Laboratory of the United States in 2006. Its key technology is to break through the limitations of traditional technology, realize automatic reset, communication control and network system control, and create an important way of remote control automation and intelligent leakage protection, which is a technological revolution in leakage protection industry. Its irreplaceable core patented technological achievements have filled the gap at home and abroad, protected by intellectual property rights, with high added value and high-tech content ahead of similar products in the same industry in the world, which will surely produce huge economic and social benefits.
After the company's GFCI products entered the American market, they quickly occupied the mainstream market in the United States because of their high cost performance, causing panic among the top 500 enterprises in the United States-Leviton Company of the United States. In 2004, the company sued four American distributors of our company in four American States for infringing their patent numbers. 6246558 dollars. Retreat and deal with, Tongling Technology Group gave up its life and chose to deal with it actively. After more than two years of hard litigation, on May 23, 2006, the American court issued a 33-page "Marman Order", clearly indicating that our products did not infringe Lefton's patents. This is the first time that a China enterprise has obtained the "Marci Order" from the US court in a Sino-US intellectual property dispute. At the same time, it sets an example for China enterprises to implement independent intellectual property protection, participate in international competition and stubbornly resist malicious lawsuits. On June 2, 2006, the People's Daily published "China Enterprises Win American Patent Lawsuit", and specially distributed articles by people's commentators, which spoke highly of our company's overseas rights protection.
