1. Complexity of Inventions: Catalytic processes and materials can be highly complex, making it difficult to draft comprehensive and clear patent applications. 2. Rapid Technological Advancements: The fast pace of innovation in catalysis requires IP experts to stay current with the latest developments and adjust IP strategies accordingly. 3. Global Protection: Securing IP protection in multiple jurisdictions can be challenging due to varying legal standards and procedures. 4. Enforcement: Enforcing IP rights, particularly in international contexts, can be difficult and costly.
