"For several years Battistelli has been aggressively pushing changes at the EPO aimed at increasing the number of patents that are reviewed and approved."
I can understand a desire to increase the number reviewed (an efficiency improvement) but why has he specified that the number approved should be increased?
"..."modernise" the EPO and keep it in line with other competing patent authorities in the US and Japan."
Ah, it's a race, an international competition? What are the prizes for winning?
