Document D01 discloses a composition consisting of a fluorinated copolymer acrylate (1.59%), noctyltriethoxysilane (20.50%), butyl acetate (9.04%) and isopropanol (20.50%) for the treatment of natural stones such as marble, granite, etc. that is applied by coating, spray, impregnation or immersion and provides hydrophobic and oleophobic properties among others (Example 23, Table 24; page 12, line 28-page 13, line 10). En consecuencia, las reivindicaciones 1 y 4-10 no cumplen con el requisito de novedad en vista a lo divulgado en el documento D01 (Art. 6.1. Ley 11/1986 ). Consequently, claims 1 and 4-10 do not meet the requirement of novelty in view of what is disclosed in document D01 (Art. 6.1. Law 11/1986). En relación a la reivindicaciones 2 y 3 relativas a la utilización de una mezcla etanol/isopropanol y su proporción relativa en la composición, si bien se consideran nuevas no así con actividad inventiva dado que es conocido del estado de la técnica la introducción de etanol y sus mezclas con otros compuestos como disolventes de formulaciones protectoras de piedras (Ver D02: Ejemplo 1), de forma que la inclusión de este disolvente en la formulación divulgada en el documento D01 sería una alternativa que un experto en la materia realizaría sin el ejercicio de esfuerzo inventivo. In relation to claims 2 and 3 relating to the use of an ethanol / isopropanol mixture and its relative proportion in the composition, although inventive activity is considered new, although the introduction of ethanol and their mixtures with other compounds as solvents of stone protective formulations (See D02: Example 1), so that the inclusion of this solvent in the formulation disclosed in document D01 would be an alternative that one skilled in the art would perform without the exercise of inventive effort Por lo tanto, las reivindicaciones 2 y 3 carecen de actividad inventiva (Art. 8.1. Ley 11/1986). Therefore, claims 2 and 3 lack inventive activity (Art. 8.1. Law 11/1986). Informe del Estado de la Técnica Página 4/4 State of the Art Report Page 4/4
