Where can I find out more about the procedure before the EPO as ISA?

Details of the procedure before the EPO as ISA can be found in Chapter 3 of the Guide for applicants: PCT procedure before the EPO (Euro-PCT Guide). It includes important information on, for example:

• how the EPO deals with applications with multiple independent claims
• how the EPO deals with lack of unity of invention
• the protest procedure
• using a written opinion established by the EPO as ISA in the Patent Prosecution Highway (PPH) procedure.
