WordPerfect became part of an office suite when the company entered into a co-licensing agreement with Borland Software Corporation in 1993. The offerings were marketed as Borland Office, containing Windows versions of WordPerfect, Quattro Pro, Borland Paradox, and a LAN-based groupware package called WordPerfect Office (not to be confused with the complete applications suite of the same name later marketed by Corel) based on the WordPerfect Library for DOS. The WordPerfect product line was sold twice, first to Novell in June 1994, who then sold it to Corel in January 1996. However, Novell kept the WordPerfect Office technology, incorporating it into its GroupWise messaging and collaboration product.
