Even during opposition proceedings, the examining division is competent to correct errors in its decision to grant, in particular errors in the decision's reasoning and bibliographic data, or formatting/editing errors in the text of the B1 publication (see H‑VI, 3.2, and H‑VI, 4).
Thus the opposition division refers to the examining division any request under Rule 140 to correct such errors filed by the patent proprietor while opposition proceedings are pending.
However, if the request for correction under Rule 140 is clearly inadmissible, i.e. the requested correction does not concern errors in bibliographic data contained in the decision to grant or formatting/editing errors in the text of the B1 publication, the opposition division continues the proceedings until the decision under Art. 101 is taken without waiting for closure of the proceedings before the examining division concerning the correction (in line with the reasoning of G 1/10). The procedural decision to continue the proceedings is appealable together with the opposition decision.
If the request for correction is admissible, the examining division processes it without delay in order to minimise or avoid delays to the opposition proceedings. The opposition division may adjourn the opposition proceedings to wait for closure of the proceedings before the examining division.
