Spanish to English Law/Patents Law (general)

This comes from the preamble to a Royal Decree on the corporate enterprise act (ley de sociedades de capital), which consolidates all previous corporate legislation: "De este modo se supera la tradicional regulación separada de las formas o tipos sociales designadas con esa genérica expresión, que ahora, al ascender a título de la ley, alcanza rango definidor". I understand the first part, and take "ascender a título de la ley" to mean " on becoming law", but not sure what to put for the last three words.
