Using Espacenet for catalysis research involves several key steps: 1. Search: Use keywords related to catalysis, such as "heterogeneous catalysis," "enzymatic catalysis," or specific catalysts like "zeolites" or "metal-organic frameworks." 2. Filter: Narrow down results using filters such as publication date, jurisdiction, and applicant name. 3. Analyze: Review the abstracts, claims, and drawings to understand the scope and novelty of the inventions.
