key combination to do what they want, such as typing phrases they often use or executing macros. The user interface has stayed almost identical from WPWin 6 through WP X5 (2010) and file formats have not changed, as incompatible new formats would require keeping both obsolete software versions and obsolete hardware around just to access old documents. Corel has catered to these markets, with, for example, a major sale to the United States Department of Justice in 2005. A related factor is that WordPerfect Corporation was particularly responsive to feature requests from the legal profession, incorporating many features particularly useful to that niche market; those features have been continued in subsequent versions, usually directly accessible with key combinations. Novell v. Microsoft antitrust lawsuit In November 2004, Novell filed an antitrust lawsuit against Microsoft for alleged anti-competitive behavior (such as tying Word to sales of Windows) that Novell claims led to loss of WordPerfect market share. That lawsuit, after several delays, was dismissed in July 2012. Novell filed an appeal against the judgment in November 2012 but this too was dismissed by the Supreme Court in 2014 without comment, ending the legal action almost a decade after it was begun. Corel buys WordPerfect from Novell Novell stated in November 1995 that it was putting its personal productivity product line up for sale. Then in January 1996 it announced that the sale of these products, primarily WordPerfect and Quattro Pro, would be made to Corel for $186 million, a large loss from the $855 million that it had originally paid to acquire WordPerfect. Novell did hold onto a few pieces that it had acquired from WordPerfect, most importantly the GroupWise collaboration product. By some estimates Novell had lost $750 million on the WordPerfect experience. The sale to Corel, which was headquartered in Ottawa, Ontario, was completed in March 1996. The head of Corel, Michael Cowpland, initially expressed optimism that Corel WordPerfect could compete effectively against Microsoft Word among business users, somewhat akin to a Coke versus Pepsi battle. However this was unsuccessful as Microsoft got many new computers loaded with Word along with Windows. The financial realities of the situation became difficult and Corel lost over $230 million for 1997. During 1998, the WordPerfect development offices in Orem were closed, affecting over 500 employees. The software engineering for WordPerfect became centred in Corel's home city of Ottawa.
