Contract Patent

Contract Patent is not a legally recognized type of patent, but a contractual clause in foreign trade contracts. It refers to an agreement between parties that one party (usually the buyer or principal) has exclusive rights to use or own specific technology, designs, formulas, or processes developed, provided, or disclosed by the other party (seller or contractor) during performance, and such rights arise solely from the contract without patent registration. It is commonly used in OEM/ODM manufacturing, technology licensing, joint R&D, or custom processing contracts. Precautions: specify the scope, territory, duration, confidentiality obligations, infringement liability, and ownership after contract termination; if third-party patents are involved, require proof of ownership or non-infringement warranty. Difference from ordinary patents: contract patents rely on contractual agreements, have no state authorization, and have weak enforceability against third parties. Difference from trade secrets: contract patents may include public or non-public technology but restrict use through contract, while trade secrets require non-public information and confidentiality measures.
