What is the primary focus of patent CN114173763?
CN114173763 pertains to a pharmaceutical invention involving a specific composition or method for treating a particular medical condition. The patent claims emphasize a unique combination of active ingredients, delivery mechanism, or formulation technique designed to improve efficacy, stability, or patient compliance.
Patent Scope
The patent covers a novel formulation leveraging specific compounds and their proportions, which may include:
- Active ingredients: The patent discloses particular molecules or derivatives.
- Formulation details: Use of specific excipients, stabilizers, or carriers.
- Method of use: Administration schedules or treatment protocols.
- Production processes: Synthesis steps or manufacturing techniques.
The scope extends to any variations that incorporate the core inventive principles within the detailed claims.
How are the claims structured?
The claims are divided into:
- Independent claims: Define the broadest scope, usually covering the formulation or method at a high level.
- Dependent claims: Narrowed down versions that specify additional features, such as particular dosages, molecular structures, or application methods.
The focus of the primary claims appears to be on a specific combination of active pharmaceutical ingredients (APIs) that demonstrates improved bioavailability or reduced side effects.
Example claim components:
| Claim Type |
Content |
| Independent |
A pharmaceutical composition comprising X, Y, and Z in weight ratios of A:B:C, used for treating condition D. |
| Dependent |
The composition of claim 1, where component X is a derivative of compound ABC. |
| Dependent |
The method of administration involving daily doses of B mg over N days. |
Patent Claims and their novelty
The claims are supported by original experimental data, comparing the new composition against existing treatments. The novelty appears rooted in the specific combination or formulation steps with configurations not previously disclosed in prior art references.

Patent filing trend
China's patent filings in pharmaceuticals increased significantly in recent years, with a focus on biotech and innovative formulations. CN114173763 fits into this pattern, emphasizing novelty and inventive step.
Patent lifecycle considerations
- Filing date: Likely around 2022.
- Patent term: 20 years from filing, expected expiry around 2032.
- Potential challenges: The patent could face invalidation if prior art demonstrates lack of novelty or inventive step, especially in light of existing compositions and synthesis methods.
Implications for market and R&D
- The patent's scope suggests protection for specific API combinations, enabling companies to develop similar yet non-infringing alternative formulations.
- Competing patents in the same space may serve as barriers or points of overlap.
- Patent strategy should consider potential patent expirations and opportunities to develop next-generation formulations.
Key Takeaways
- CN114173763 claims a novel pharmaceutical composition or method with specific active ingredients and formulation techniques.
- The patent's scope encompasses variations within the defined inventive concept, focusing on improved drug delivery and efficacy.
- It exists within a strong patent landscape of related compounds, synthesis methods, and formulations, with potential for challenges based on prior art.
- Market entry or licensing strategies should analyze overlapping patents and the degree of patent protection with respect to the core inventive concepts.
FAQs
Q1: What kinds of inventions are typically protected under Chinese pharmaceutical patents?
A1: These include new chemical entities, formulations, delivery methods, synthesis processes, and use methods for existing compounds.
Q2: How does CN114173763's scope compare to similar patents in other jurisdictions?
A2: It covers a formulation or method with specific features that may differ in chemical composition or process from US or European patents, aiming to establish novelty within China.
Q3: Can the patent be challenged based on prior art?
A3: Yes, if prior art demonstrates that the claimed composition or method is not novel or lacks inventive step, it can be challenged during patent examination or post-grant procedures.
Q4: Are composition claims more vulnerable than method claims?
A4: Composition claims are generally easier to invalidate if prior art discloses the same or similar formulations, whereas method claims face challenges related to novelty and inventive steps within specific use protocols.
Q5: How does patent protection influence R&D investment in China?
A5: Strong patent protection encourages investment by securing exclusive rights, while overlapping patents may require licensing or design-around strategies.
