Pinming Technology Co., Ltd, a Chinese construction software provider, has filed a lawsuit against a former employee and his company, alleging copyright infringement over its engineering pricing software and seeking 12.2 million yuan in damages, the company said in a regulatory filing on May 16.
The lawsuit, filed at the Hangzhou Intermediate People’s Court in Zhejiang province, names Yunyi Fengcheng Technology (Hangzhou) Co., Ltd and its legal representative, Huang Xi’an, as defendants. The court has accepted the case under docket number (2026) Zhe 01 Min Chu No. 1324.
Pinming alleges that Huang, whose responsibilities at the company included direct oversight and development of the Pinming Engineering Pricing Software, left Pinming and later became legal representative and the largest shareholder of Yunyi Fengcheng. The defendant then launched "Fengcheng Digital Pricing Software V1.0" — a product directly competing with Pinming's own "Pinming Shengxuan V7.0."
According to Pinming's filing, the company began developing its engineering pricing software on January 1, 2010, and completed the initial version in 2012. The latest iteration, version 7.0 (branded as "Pinming Shengxuan V7.0"), received a computer software copyright registration certificate on January 27, 2022.
Pinming claims that the competing software shows "high consistency" in unique identifiers, constituting clear copyright infringement. The company is asking the court to order an immediate halt to the alleged infringement, a public apology on national media and the defendant's official website, plus 12.2 million yuan to cover economic losses and legal costs.
Pinming Technology, which listed on Shanghai’s STAR Market in 2021, focuses on digital construction applications for the construction phase. Its main businesses include construction information software and smart construction site products. The company holds more than 330 software copyrights, according to its website.
Yunyi Fengcheng, founded in January 2025, provides digital solutions for the construction sector, including housing, municipal works, water conservancy, and transportation. Its core product is the "Fengcheng Digital Pricing Software."
