Description
Regarding the European 3 403 942 (DE 50 2012 015 616)
[0001] The 7th Senate (Voidance Senate) of the Federal Patent Court, based on the oral hearing of March 27, 2025, has decided recognized as rightful: 1. European patent 3 403 942 is partially declared invalid with effect for the territory of the Federal Republic of Germany by amending its patent claims to read as follows:
Claims
[1] Palette (1) 1.1 with an essentially rectangular basic structure (2) and 1.2 four side surfaces (3) enclosing the basic structure (2), 1.2.1 of which two side surfaces (3) are arranged on opposite sides of the basic structure (2) and are aligned parallel to each other, 1.3 wherein the basic structure (2) has a flat top and bottom surface (4, 5) apart from stiffening structures and 1.4 wherein feet (6) are arranged on the underside (5) to support the base structure (2), 1.5 wherein at least two of the four side faces (3) have at least one recess (7) for receiving a display extension (8) of a display base, characterized by , 1.6 that the palette has inwardly offset corners which are designed such that extensions at the corners of the display base can be folded over the inwardly offset corners, 1.9 wherein the feet are each formed by a funnel-shaped depression extending from the top, from the bottom of which a central truncated pyramid extends to the top. [2] Pallet (1) according to claim 1, characterized by , that the recess (7) extends over the vertical extent of the side surface (3). [3] Pallet (1) according to claim 1 or 2, characterized by , that the recess (7) has vertically extending undercuts (9) at its vertically extending boundaries, wherein the undercuts (9) preferably extend over the entire vertical extent of the recess (7). [4] Pallet (1) according to any one of claims 1 to 3, characterized by , that the horizontal cross-sectional area (10) of the recess decreases in the direction from the underside (5) of the base structure (2) to the top side (4) of the base structure (2). [5] Pallet (1) according to claim 4, characterized by, that the horizontal cross-sectional area (10) is rectangular or semicircular. [6] Pallet (1) according to claim 3 or according to one of claims 4 to 5, insofar as these are related back to claim 3, characterized by , that the vertically extending undercuts (9) of the recess (7) have a horizontally extending recess (11), which is preferably designed in a slot-like form. [7] Palette (1) according to any one of claims 1 to 6, characterized by , that the basic structure (2) has at least one slot-shaped receptacle (13) for a fastening means along an imaginary line running parallel to one of the side surfaces (3). [8] Palette (1) according to any one of claims 1 to 7, characterized by, that the two pairs of opposite side surfaces (3) have different lengths, wherein the direction of the longer side surfaces (3) is referred to as the longitudinal direction, wherein along a longitudinally extending center line (14) two longitudinally spaced receptacles (13) for fastening means are provided, which are preferably rectangular in shape. [9] Palette (1) according to claim 8, characterized by , that the recordings (13) arranged on the center line (14) have a locking mechanism. [10] Pallet (1) according to any one of claims 1 to 9, characterized by , that at least one side surface of a foot (6) has a recess (15) for attaching packaging material. [11] Pallet (1) according to any one of claims 1 to 10, characterized by , that fixing sections (19) for the attachment of fixing straps are provided on the underside (5) of the basic structure (2). [12] Pallet (1) according to any one of claims 1 to 11, characterized by , that the basic structure (2) has alternating upwardly open and downwardly open depressions / ribs (18) which are stiffened by cross braces. [13] Palette (1) according to any one of claims 1 to 12, characterized by , that the pallets (1) can be stacked on top of each other.
