FAQs
Q1: Can the claims of CN107376071 be challenged on grounds of novelty?
A: Yes. Prior art reviews focusing on chemical structures and therapeutic claims could potentially challenge the novelty if similar compounds or methods are disclosed elsewhere.
Q2: Are method claims in this patent enforceable without a specific therapeutic indication?
A: Method claims typically require proof of clinical efficacy to be enforceable, especially in therapeutic contexts.
Q3: How does this patent influence competitor R&D efforts?
A3: It limits freedom to operate in the protected chemical class and therapeutic niche, prompting competitors to design around or challenge the patent.
Q4: What strategies can extend the patent’s protection?
A4: Filing divisional applications, patent term extensions, or developing new formulations and combinations can expand protection.
Q5: How does the patent landscape in China compare with US and Europe for similar compounds?
A: China emphasizes structural claims and fast-track examination; US and Europe tend to scrutinize inventive step more closely but also provide broader claim interpretation avenues.
