Objections of the Office: a patent application may be examined at most three times. If the third examination report is not favorable, the application will be rejected. 

Application kept secret: if applied for a secret patent. 

Opposition to application filed: not provided for. 

Corrections: possible. 

Publication: entire patent specification as filed is available on expiration of eighteen months from the filing date or, where priority is claimed, from the earliest priority date.

Working of patent: compulsory. According to the established case law, importation, sales or local manufacture and sales under a license are considered as meeting working conditions. An application for recordal of use or non-use may be filed within three years following the publication of a notice of grant of the patent. Declaring use or non-use may not prevent compulsory license requests that may be sought by introducing a lawsuit, i.e. compulsory license requests may not be filed at the Patent Office. Applying for recordal of use/non-use may dissuade third parties, who notice that an application for the recordal has been filed with the Patent Office, from requesting a compulsory license.

Opposition to granted patents: possible. 

Expropriation: not provided for. 

Nullification: a patent may be nullified upon the decision of the Patent and Trademark Office or a competent court if (a) the patent comprises unpatentable subject matter, the subject matter of the patent is found to be not novel, not to include inventive step or not industrially applicable; (b) the patent does not disclose the invention in a manner sufficiently clear and complete for it to be carried out by a person skilled in the art; (c) it is proved that the subject matter of the patent exceeds the scope of the application filed or, the subject matter of the patent exceeds the scope of the application filed initially, in the case where the certificate is based on a divisional application filed or on another application filed subsequent to the usurpation of the right to a patent; (d) it is proved that the applicant is not entitled to the right to request the patentor; or (e) it is proved that the scope of protection of the patent as granted is exceeded. A nullification request in accordance with (d) may be filed only by the inventor or his successors in title. Partial nullification of a patent is possible.

Validation of invalidated patents: the proprietor of a patent who was unable to observe a time limit that resulted in the rejection of a patent would have the possibility to have his rights re-established upon request if it is shown that due care had been taken to prevent an adverse outcome.
