Why didn't Microsoft sue WPS Office for infringement?

No matter how Jinshan changes, even if 100% imitates Office, Microsoft can't sue it for infringement, because the technology they use is different, and the underlying technology is different. If it is a question of format, there is a format agreement between them. In other words, although the functions of office software are similar, if their substantive codes are different, it cannot constitute an infringement of the copyright of Microsoft computer software.

1996, Microsoft took the initiative to find Jinshan, and Microsoft hoped that Jinshan and Microsoft * * * would share the WPS format, and the two were compatible. Then, the two sides signed an agreement-both sides read each other's files through the RTF format in the middle layer of their respective software. The WPS format is open to Microsoft, which means that the original WPS users can use Microsoft Word to open and edit documents in WPS format. At the same time, WPS can also open and edit documents in Office format.

It is this seemingly simple hope and requirement that makes Microsoft seize the China market almost effortlessly. The first thing Microsoft did when it entered China was to find a way to transfer the old users of WPS to the Word platform. Microsoft has done a good job in publicity, adopting the way of bundling sales and conniving at piracy (because it is not illegal for individuals to use piracy), which quickly occupied the market share in China and almost put Jinshan into bankruptcy. Lei Jun was forced to tear down all WPS codes and redesign WPS to be compatible with Microsoft. In August 2002, Lei Jun proposed to Qiu Bojun to rewrite WPS for 35 million yuan in three years, and Qiu Bojun agreed after silence.

On September 12, 2005, the new version of WPS was launched, and it was announced that it would be free for individuals forever. This is the first compromise of WPS. Its relationship with the old WPS may be limited to the continuation of the same name. This version of WPS does not use a line of code from the old version of WPS, but is completely transformed and completely adopts Microsoft Office standards. The goal is to achieve "word-to-word, line-to-line, page-to-page" compatibility. The software interface and function are exactly the same, and the technology has surpassed. Since 20 12, WPS has been developed using Qt framework, becoming the world's first cross-platform office software, supporting Windows,

Linux, Android, IOS, all major platforms.
