For enterprises, it is a simple, effective and very low-cost way to prevent competitors from obtaining granted by monitoring the status of competitors' patent applications and submitting third-party public opinions to the patent authority.
There are only a few countries in the world that have set up very little official fees for third-party public opinions, and the public does not need to prepare detailed reasons for invalidation, and most countries can submit public opinions anonymously without providing any personal information. By sending it to the Intellectual Property Office, the submission of the third-party public opinion has been completed, which can effectively avoid direct conflicts with competitors.
