Sybase’s database code is doing quite well, in its perfectly-legal descendant, Microsoft SQL Server (Microsoft partnered with Sybase—and Ashton-Tate—on porting Sybase’s software to OS/2 in a deal that included Microsoft getting exclusive rights to make the database on x86 shortly after its first release, and when the deal ended Microsoft kept the rights to continue developing and marketing the database, though Sybase was then also allowed to enter the x86 market.)
