This case involves an appeal by WEPA Nederland B.V. concerning overpaid court fees related to a proceeding with Essity Hygiene and Health Aktiebolag over the preservation of evidence for the patent EP 3 289 139. The Local Division of The Hague originally allowed the preservation of evidence, leading WEPA to appeal. WEPA argued that they paid incorrect appeal fees, believing the fee should only be 5,000 EUR rather than the 14,600 EUR they paid. The Court of Appeal decided in favor of WEPA, determining that the correct fee was indeed 5,000 EUR since the value of the action was up to 500,000 EUR without additional value-based fees. Consequently, the court ordered a reimbursement of 9,600 EUR to WEPA.
