If you get protection through a patent, you have exclusive
rights to commercial exploitation of your invention. The invention
must not have beenbe new, i.e. never have been manufactured
or described before. This means that your own invention must not
have been described anywhere before you submit your patent
application. If you, for example, have been interviewed in local
press about your invention or participated in an exhibition, you
have destroyed the opportunity for applying for a patent on your
invention. File first - talk later.
The invention must be reproducible and have a technical character.
The invention must be inventive. This means that it will stand out from other inventions in the same area.
