We pay the Patent Office(s) and local agents (if required) after we receive the invoice payment. This period posts potential currency fluctuations. The foreign exchange deposit is then used when the exchange rate used in the invoice is insufficient to cover the currency fluctuation. This is an amount of up to 10% of the sum payment of the official fee, transaction fee, recipient bank fee, local agent fee, surcharge fee and postal/fax fee. We pride ourselves on saving renewal costs for our customers.
When the foreign exchange deposit is not used in full, a refund will be made by PatentRenewal.com in a year or the amount exceeds the value or equivalent of USD 1000 or EUR 900.
