Currently NEC produces StarOffice collaborative software (unrelated to the one discussed here) in Japan. The two brands existed because a StarOffice brand was owned by another company in certain Asian countries. Otherwise the features were identical to StarOffice. It also included additional fonts for the East Asian market, resulting in slightly larger installation footprint. It included Japanese, Korean, Simplified Chinese and Traditional Chinese interfaces. StarSuite was the version of StarOffice with Asian language localization. In March 2009, a study showed that StarOffice only had a 3% market share in the corporate market. Sun Microsystems acquired the company, copyright and trademark of StarOffice in 1999 for US$73.5 million, as it was supposedly cheaper than 42,000 licenses of Microsoft Office. In 1998 Star Division began offering StarOffice for free. Until version 4.2, Star Division based StarOffice on the cross-platform C++ class library StarView. From this time onwards Star Division marketed its suite under the name 'StarOffice.'

Later, the integration of the other individual programs followed as the development progressed to an office suite for DOS, IBM's OS/2 Warp, and for the Microsoft Windows operating system. It was later ported to the Amstrad CPC (marketed by Schneider in Germany) under CP/M and later ported to the 8086-based Amstrad PC-1512, running under MS-DOS 3.2. Börries formed Star Division in Lüneburg the following year. StarWriter 1.0 was written by Marco Börries in 1985 for the Zilog Z80.

StarOffice was acquired by Sun Microsystems in 1999, which released the source code the following year as a free, open source office suite called, which subsequent versions of StarOffice were based on, with additional proprietary components. The software originated in 1985 as StarWriter by Star Division, which marketed the suite with some success, primarily in Europe. It included templates, a macro recorder, and a software development kit (SDK).

StarOffice supported the XML file format, as well as the OpenDocument standard, and could generate PDF and Flash formats. StarOffice is a discontinued proprietary office suite, its source code continues today in derivative open-source office suites Collabora Online and LibreOffice.
