Ensuring non-infringement involves several steps: 1. Conducting a thorough patent search: Before developing a new catalyst or process, it is essential to review existing patents to identify potential conflicts. 2. Consulting with patent experts: Legal and technical experts can provide guidance on whether a new development may infringe on existing patents. 3. Developing alternative methods: If a potential infringement is identified, alternative methods or modifications can be explored to avoid violating patent rights.
