interest being compounded on the last day of each calendar quarter, provided, however, that in no event shall said annual interest rate exceed the maximum legal interest rate. Each such royalty payment when made shall be accompanied by all interest
so accrued. Said interest and the payment and acceptance thereof shall not negate or waive the right of Rochester to seek any other remedy, legal or equitable, to which it may be entitled because of the delinquency of any payment.

patent application or under any patent or patent claim that is held invalid in a decision by any court of competent jurisdiction, all such payments shall be paid to an interest-bearing escrow account established by the parties until a final decision
