Bristol Technology Inc. was a software development company founded in January 1991 by Keith, Ken, and Jean Blackwell.
The company's original product idea, Wind/U, was an implementation of the Windows API (application programming interface) on non-Windows operating systems (such as UNIX).
Windows Interface Source Environment (WISE) was a licensing program from Microsoft which allowed developers to recompile and run Windows-based applications on UNIX and Macintosh platforms.
In the lawsuit, Bristol sought unspecified damages for and injunctive relief from Microsoft's alleged anti competitive behavior.
Subsequently, the jury ruled that operating systems were not a definable market, thus Bristol did not have standing to sue under antitrust law.
The company was purchased by Hewlett-Packard in 2007 for the purpose of adding TransactionVision to HP's Business Technology Optimization (BTO) line of products.
