With respect to claim 1, Biec discloses a levelling piece (22) for cladding panels that has an inverted T-shaped profile (See Figure 11A) with a flat base (26) from which an inverted U-shaped element (28) emerges perpendicularly, and wherein the inverted U-shaped element (28) is joined to the base (26) by respective arms defining an opening (30), the upper middle region of the inverted U-shaped element having a thickening of variable thickness (See Figures 11A and 11G) that decreases gradually defining a pointed termination (See Figure 11G). PNG media_image1.png 334 504 media_image1.png Greyscale PNG media_image2.png 372 476 media_image2.png Greyscale Referring to claim 2, Biec sets forth a levelling piece (22) wherein the thickening has a gradual increase in thickness extending in a radial direction (See Figure 11G) in the upper middle region of the inverted U-shaped element (28), defining a perimeter of variable thickness in the upper middle region of the inverted U- shaped element. PNG media_image2.png 372 476 media_image2.png Greyscale In regards to claim 3, Biec teaches a levelling piece (22) wherein the thickening is defined by a projection extending from one side to an opposite side of the inverted U-shaped element (See Figure 11G), generating a thickening in a plane parallel to the base and wherein the thickness of the inverted U-shaped element which decreases gradually as it approaches the end opposite approaching away from the base, defining a pointed termination (See Figure 11G). PNG media_image2.png 372 476 media_image2.png Greyscale Regarding claim 4, Biec shows a levelling piece wherein the thickening is defined by a projection extending from one side to an opposite side of the inverted U-shaped element (See Figure 11G), generating a thickening in a plane parallel to the base, and wherein the thickness of which the inverted U-shaped element decreases by way of steps as it approaches the end opposite approaching away from the base, defining a pointed termination (See Figure 11G). With regards to claim 5, Biec discloses a levelling piece wherein the thickening is defined by a projection (See Figure 11G) arranged centered in the upper middle region of the inverted U-shaped element, and wherein a thickness of the projection decreases gradually as it approaches the end opposite approaching away from the base, defining a pointed termination (See Figure 11G). Referring to claim 6, Biec sets forth a levelling piece wherein the arms have notches (See Figure 12A) at respective ends which are joined to the base. PNG media_image3.png 320 362 media_image3.png Greyscale In regards to claim 7, Biec teaches a levelling piece wherein ends of the base farthest away from the inverted U- shaped element have a reduction in thickness (See Figure 11G). Regarding claim 8, Biec shows a levelling piece wherein the base has beveled corners (See Figure 11C). PNG media_image4.png 328 504 media_image4.png Greyscale With respect to claim 9, Biec discloses a levelling piece wherein the arms have notches at respective ends which are joined to the base (See Figure 11C). Referring to claim 10, Biec sets forth a levelling piece wherein the arms have notches at respective ends which are joined to the base (See Figure 11C). In regards to claim 11, Biec teaches a levelling piece wherein the arms have notches at respective ends which are joined to the base (See Figure 11C). Regarding claim 12, Biec shows a levelling piece wherein the arms have notches at respective ends which are joined to the base (See Figure 11C).
