No litigation or other expenses are to be deducted from Gross Recoveries. In calculating the amount due Jenkens, no litigation or other expenses are to be deducted before applying the percentage to a Gross Recoveries item. “Gross Recoveries,” as used in this Agreement, means:

(i) all royalties, license fees and other payments made or accruing under all license agreements and similar agreements entered into in connection with the Patents for the right to use or practice any claimed inventions described therein, and (ii) all amounts recovered in enforcement actions, whether by way of judgment or compromise and settlement, relating to the Patents.
