Before the patent is published or announced, novelty will not be lost if the applicant withdraws the application (it should be corrected here that the inventor has no right to request withdrawal, only the applicant has the right to withdraw).
Paragraph 2 of Article 22 of the Patent Law stipulates: Novelty means that the invention or utility model does not belong to the existing technology; and no unit or individual has filed a patent for the same invention or utility model before the filing date. An application has been filed with the Patent Administration Department of the State Council and recorded in the patent application documents or announced patent documents published after the application date.
Although your company applied for a patent, it voluntarily withdrew it before it was announced. Therefore, it is neither an existing technology nor a conflicting application. Therefore, it will not affect the novelty of subsequent applications.
The patent application has not been published and cannot be regarded as prior art in the patent review database. Therefore, your company can continue to apply for follow-up applications.
