Pre-Application Searches (PAS) :

At first, an invention is just an idea. Many details are not even known or recognized as relevant parts. A novelty search based on a vague idea can only result in a vague picture of the prior art. The patent application process is difficult, time consuming and expensive; therefore, the inventor should conduct a “Pre- Application Search” (PAS) before filling a patent application. In this search, the inventor should look for any printed publications, public knowledge, or patents already issued in his country or a foreign country that may relate to the particular invention.
