The document discusses patentable subject matter requirements for software and business method inventions in China and Taiwan by comparing them to a US court case. In both China and Taiwan: 1. Software and business method inventions must satisfy a technical effect test to be patent-eligible, involving a technical solution to a technical problem. 2. Business methods alone are not patentable, but may be patentable if technical features are involved in carrying out the business method. 3. Both process and product claims are acceptable, but process claims for software must involve hardware or machines to implement the method.
