Adobe threatening software creators in US and EU with Palette Patent
In summer 2001 Adobe attacked Macromedia for infringing on its US patent no 5546528 which lays claim to the idea of adding a third dimension to menus by grouping them as tabbed palettes one behind the other. The European Patent Office (EPO) has illegally granted EP0689133 with exactly the same set of claims and priority date of 1994-06-23 on 2001-08-06, after five years of examination period. Many programs, including free software such as The GIMP, infringe on this patent and will therefore be at the mercy of Adobe, if the EPO's practise of granting software patents is made enforcable by a Directive from the European Commission.
