English to Italian Law/Patents Law: Patents, Trademarks, Copyright

Si tratta del seguito della frase per cui avevo chiesto aiuto venerdì... "The purchase of this product includes a limited, non-transferable immunity from suit under the foregoing patent claims for using only this amount of product solely in environmental testing, quality control/quality assurance testing and food testing applications including *reporting results of purchaser’s activities for a fee* or other commercial consideration, and also for the purchaser’s own internal research". Non riesco a trovare un modo decente per rendere la parte di frase tra gli asterischi. Qualche idea? Grazie!
