FAQs
Q1: What makes a patent claim in pharmaceuticals broad or narrow?
A: Broad claims cover extensive chemical classes or uses, providing wide protection, while narrow claims focus on specific compounds or formulations, limiting scope but possibly reducing invalidity risk.
Q2: How does Spanish patent law compare to the rest of Europe regarding pharmaceuticals?
A: Spain applies EU patent standards (similar to EPO), requiring novelty, inventive step, and industrial applicability. It offers mechanisms like SPCs for extended protection, aligned with EU regulations.
Q3: Can a patent like ES3036965 be challenged successfully?
A: Yes, via invalidation procedures for lack of novelty or inventive step, or through opposition within the opposition period after grant, though strategic drafting aims to mitigate this.
Q4: What role do use claims play in pharmaceutical patents?
A: Use claims protect specific therapeutic applications, potentially extending patent life beyond composition patents if the use is novel and inventive.
Q5: How important is the patent landscape in planning drug development in Spain?
A: Vital. It informs about existing protections, potential overlaps, and opportunities for innovation or freedom to operate, influencing R&D and commercial strategies.
