The binding legal principles established by this judgment are: (1) In interpreting an ambiguous term such as "applicable license fee" in a software license agreement, the term should be interpreted with reference to the fee negotiated between the particular parties, including any applicable discounts, rather than as a reference to the supplier's standard or list price, unless the contract expressly provides otherwise. (2) A contractual clause requiring payment of fees for unlicensed copies discovered through audit should not be interpreted as a penalty clause that gives the licensor more than its actual damages, but rather as a mechanism to facilitate proof of the number of breaches and consequent damages. (3) The contra proferentem rule applies to standard form contracts: where ambiguity exists in terms drafted by one party, the interpretation least favorable to the drafting party should be adopted. (4) In claiming damages for breach of a maintenance agreement read with a license agreement where unauthorized copies have been made, the proper measure of damages is to calculate what maintenance fees would have been payable if the unauthorized copies had been properly licensed, thereby placing the innocent party in the position it would have occupied had both contracts been properly performed. (5) Under a maintenance agreement calculated on a per-copy basis, fees are payable for all copies the licensee is entitled to use, regardless of whether all copies are actually used.
