The invention may not form part of the prior art at the moment the (first) patent application is filed. The prior art is defined as all information which has been made available to the public anywhere in the world. An invention which is known for instance on internet or in another country is therefore no longer new. Very important is that the novelty of your invention can also be nullified by your own actions. A patent application, in which the invention is described, must be filed before you go public with your invention, for instance in order to approach outsiders. It is worth noting here that the product to be protected and/or the method to be protected does not have to be wholly new: the invention to be protected can be an improvement to an existing product.
