StarOffice , known briefly as Oracle Open Office before being discontinued in 2011, was a proprietary office suite . It originated in 1985 as StarWriter by StarDivision , which was acquired by Sun Microsystems in 1999. Sun Microsystems, in turn, was acquired by Oracle Corporation in 2010.
StarOffice supported the OpenOffice.org XML file format, as well as the OpenDocument standard, and could generate PDF and Flash formats. It included templates , a macro recorder, and a software development kit (SDK).
The source code of the suite was released in July 2000, creating a free , open source office suite called OpenOffice.org , which subsequent versions of StarOffice were based on, with additional proprietary components. 
StarWriter 1.0 was written by Marco Börries in 1985 for the Zilog Z80 . Börries formed StarDivision in Lüneburg the following year.  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. 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. From this time onwards StarDivision marketed its suite under the name "StarOffice."
StarSuite was the version of StarOffice with Asian language localization. It included Japanese , Korean , Simplified Chinese and Traditional Chinese interfaces. It also included additional fonts for the East Asian market, resulting in slightly larger installation footprint. Otherwise the features were identical to StarOffice.
The two brands existed because a StarOffice brand was owned by another company in certain Asian countries.  Currently NEC produces StarOffice collaborative software in Japan.  After Oracle acquired Sun Microsystems (in January 2010) it renamed both StarOffice and StarSuite as "Oracle Open Office".

The resultant free/open source software codebase fork continued development as OpenOffice.org , with contributions from both Sun and the wider OpenOffice.org community. Sun then took "snapshots" of the OpenOffice.org code base, integrated proprietary and third-party code modules, and marketed the package commercially.

Oracle Open Office
On 15 December 2010, Oracle released Oracle Open Office 3.3, based on OpenOffice.org 3.3 beta, and a web-based version called Oracle Cloud Office .   The suite was released in two versions, sold at €39 and €49.95. 
Pricing and licensing
Traditionally, StarOffice licenses sold for around US$70 , but in 2004, Sun planned to offer subscription-based licenses to Japanese customers for about ¥1,980 ( US$17 ) per year (Becker, 2004). P. Ulander, a desktop products manager for Sun, acknowledged that Sun planned to expand subscription-based licenses to other countries as well. As of January 2009 Sun's website offered StarOffice for US$34.95 . 
Sun used a per-person license for StarOffice, compared to the per-device licenses used for most other proprietary software. An individual purchaser gains the right to install the software on up to five computers. For example, a small-business owner can have the software on laptop, office and home computers, or a user with a computer running Microsoft Windows, and another running Linux, can install StarOffice on both computers.
In 2010 StarOffice 9 Software was no longer offered free of charge to education customers, but StarOffice 8 could still be used without charge. The free OpenOffice.org 3.0, with the same functionality as StarOffice 9, could also be used. Sun also offered free web-based training and an online tutorial for students and teachers, free support services for teachers (including educational templates for StarOffice) and significantly discounted technical support for schools.
