The royalty rate for printing a book (a novel, lyrics or music) globally, or its download, for sale varies from 20-30% of the suggested retail sales value, typically 20–25%, for a new writer that is taken by the publisher/distributor. The payment is made by the publisher/distributor and corresponds to the agreement (license) between the writer and the publisher/distributor as with other music royalties. The cost of such services arises from delineating the skill-mix and 'man'-hours of effort involved (domestic and expatriate personnel) and providing for supervision overhead. The costs of different skills is in the public domain and can be readily estimated. The overhead percentage, however, is a negotiated element. In the event Inventor takes action to enforce any patent on the Licensed Product, Company shall provide full cooperation, at Inventor's expense, to support such action. The party that bears the full cost of an enforcement action shall be entitled to recover all proceeds recovered through such action. Any right granted in this Agreement greater than that permitted under Public Law 96-517, or Public Law 98-620, shall be subject to modification as may be required to conform to the provisions of those statutes. In many contracts involving the use of knowhow (and associated IP), 'technical assistance' may be encountered as a part of the contractual process, particularly in developing country contracts. The assistance comprises services which are not in the nature of IP but are needed by the licensee to accomplish its objectives.
