Frequently Asked Questions (FAQs)
1. How does patent CN120789028 compare with similar international patents?
While specific claims vary, CN120789028 appears to be broader, covering both compound and formulation compositions, aligning with global trends to secure comprehensive protection. However, differences in scope and language influence enforceability.
2. What are the potential challenges to the validity of this Chinese patent?
Prior art references, especially prior disclosures of similar compounds or methods, can threaten validity. Overly broad claims might also be invalidated if not sufficiently supported or if they lack inventive step.
3. How can patentees maximize the patent's enforceability?
By narrowing claims to core inventive features, including detailed process steps, and ensuring comprehensive disclosure to meet Chinese patent standards.
4. What is the strategic importance of this patent within the pharmaceutical industry?
It offers protection over a potentially therapeutically valuable compound or formulation, helping the patent holder maintain market exclusivity, support licensing, or block competitors.
5. Are there opportunities for patent infringement analysis or freedom-to-operate assessments?
Yes. A thorough comparison with other patents—especially prior art in China and internationally—is critical. Commercial entities should evaluate whether competing formulations or manufacturing processes infringe or can be designed around.
