Borland argued that most cars operate the same, but they are not necessarily made the same. So, Lotus could not rationally "own" the way its program behaved. The district court ruled in favor of Lotus, but the appellate court ruled that the 1-2-3 menus were functional and not copyrightable. The case went all the way to the U.S. Supreme Court which split 4 to 4 (Justice Stevens recused himself). This left the lower court ruling intact, which was a victory for Borland. However, the broader issue of whether a company can own and protect the way its program behaves remained unresolved. By the time the case was resolved, Borland no longer owned Quattro Pro. Borland sold the spreadsheet to Novell six months before the final decision was handed down. Quattro Pro began as a DOS program (like Lotus 1-2-3) but with the growing popularity of Windows from Microsoft, a Windows version of Quattro needed to be written. There was almost nothing from the DOS code that could be moved to the Windows project, so the Quattro Pro for Windows (QPW) was written from scratch. Both the QPW and Paradox for Windows codebases (the latter being another Borland database application) were based on Borland's internal pilot project with object oriented UI code for Windows. This project ran simultaneously with the Borland language group investigating the desirability of a C++ compiler, and the company decided to make a bet on C++. However, the C++ compiler was not ready at first, and OO code for both projects was started in C with OO emulation through macros. As the Borland Turbo C++ compiler became available internally the projects converted to using C++. Charlie Anderson was put in charge of the project and he soon had Istvan Cseri, Weikuo Liaw, Murray Low, Steven Boye, Barry Spencer, Alan Bush, Dave Orton, Bernie Vachon, Anson Lee, Tod Landis, Gordon Ko and Chuck Batterman working on the project. Other engineers joined later. Eventually the team numbered nearly 20. The object model was inspired by the NeXT object model, modified by Mr. Cseri. Liaw and Mr. Spencer were in charge of the spreadsheet engine (written in assembly language) while Mr. Low wrote a large chunk of the UI. The product was internally codenamed "Thor" for the Norse god of Thunder.
