Grant Statistics

It may be interesting to note that the grant rate for EP patents fell below 50% last year:

Apparently “the EPO’s announcement means that the allowance rate at each of the trilateral offices will be below 50% — with the EPO at 49.5%, the JPO at 48.9%, and the USPTO at 42%. Taken collectively, the average rate of allowance stands at 47.5%.”

There are also some interesting statistics on filing in different technical fields: electronics is up but biotech is down.
