Article 58.
§ 1. If the deadline is infringed it may be rescheduled at the request of an interested party if it appears probable that the infringement was not caused by that party.
§ 2. A request to reschedule the deadline should be made within 7 days of the reason for the deadline’s infringement coming to an end. However, the actions for which the deadline was set must be carried out simultaneously with the request being made.
§ 3. It is not possible to reschedule the deadline for making the request referred to in § 2.

However, provisions of article 243(1) deals with the time limits set by the Polish Patent Office, while the deadline for The request for restitution of a term to file a request on rehearing is a term defined in the APC.

Article 243
1. Unless otherwise stipulated in this Law, where in the course of proceedings a time limit to perform an act requisite, under this Law, for continuance of the proceeding has not been observed, the Patent Office may, at the party’s request, restore the time limit, provided that the party provides a plausible explanation that non-observance was without fault on its part.

2. Subject to paragraph (4), the request referred to in paragraph (1) shall be submitted to the Patent Office within two months from the date on which the reason for non-observance has ceased to exist, however not later than within six months from the date of the expiry of that time limit. At the same time, the requesting party shall be required to perform the act in respect of which the time limit was fixed.

3. A time limit to submit the request referred to in paragraph (2) shall not be restorable.

4. Where a decision has been taken on discontinuance of the proceeding for the reason of failure to observe a time limit for performance of a specified act, that decision, at the party’s request for re-examination of the matter, may be reversed, provided that the party provides in the request a plausible explanation that the non-observance was without fault on its part, while performing, at the same time, the act in respect of which the time limit was fixed.
5. Where the time limit for filing an application for the purpose of preserving the right of earlier priority or the time limit for furnishing a document expires on a day on which the Patent Office is closed to the public, the application or the document received on the first subsequent day on which the Patent Office is open to the public shall be deemed to have been received within the time limit concerned.

6. In respect of time limits, to which paragraph (1) is not applicable, and the non-observance of which has been caused by exceptional circumstances, the provisions on suspension of the course of negative prescription caused by acts of God shall apply accordingly. In such cases, the Patent Office shall give orders after having been furnished with relevant evidence by the interested party.

7. Notwithstanding the provisions of paragraphs (5) and (6), the Patent Office shall secure the reception at any time of day of letters delivered by interested persons.

The fact that this applies only to time limits set by the PPO is showed in wording of article 243(2) of the IPL. This whole provisions of article 243 of the IPL apply only to certain categories of terms. This limitation results from the wording of this provision.
