Within two months of the Opposition written decision, any party adversely affected can file an Appeal. Quite simply, if you did not get the result you needed first time round, you need to appeal.
While the Appeal is often seen as the final say at the EPO, a “Petition for Review” can also be filed by any party adversely affected by a decision of the EPO Board of Appeal if there were for example procedural violations. If successful, the “Enlarged Board of Appeal” can re-open proceedings before the Board of Appeal.
Questions of law can also be referred to the EPO Enlarged Board of Appeal at any stage.
