Can I withdraw my Taiwanese application before it is published?

Yes. If the patent application is withdrawn within 15 months from the filing (or priority) date, it will not be published. If withdrawal is requested later than that, the application will be published if the preparations for publication are already under way, but all subsequent procedures will be discontinued.
