PREVIOUS SEARCH

It is recommended to perform a prior search before filing a patent application. This search is to evaluate the state of the technology related to the material being presented, in order to determine whether the invention is in fact new and innovative. If the invention is not new, but presents, for example, a functional improvement to the already existing object, a utility model application may be filed. Some search engines are listed below:
