Who founded Ashton-Tate?
Ashton-Tate
In June 1982 Cole hired Rod Turner as the director of OEM sales for Ashton-Tate. In a few weeks Turner solved a sales commission plan issue, that had been bothering George Tate for some time, with the top performing salesperson (Barbara Weingarten, now Guerra), and Tate and Cole promoted Turner to be Vice President of world-wide sales three weeks after his initial hire. Turner was approximately the 12th employee of Ashton Tate. Since the company was truly boot-strapped, using no external venture capital, the founders did not make a practice of hiring experienced veterans, and most of the team at Ashton-Tate were young and enthusiastic, but inexperienced. Jim Taylor was responsible for product management in the early days, and worked closely with Wayne Ratliff and the other key developers on dBASE II. In 1982 Perry Lawrence and Nelson Tso were the two developers who were employed at Ashton-Tate, while Wayne Ratliff employed Jeb Long from his royalty stream.

When a number of "clones" of dBase appeared in the 1990s, Ashton-Tate sued one of them, FoxPro, over copyrights. On December 11, 1990, Judge Hatter issued an order invalidating Ashton-Tate's copyrights in its own dBASE products. That ruling was based on a legal doctrine known as "unclean hands". Judge Hatter explained that Ashton-Tate knew that the dBase program development was based on JPLDIS, and that fact was kept hidden from the Copyright Office.
