What is the scope of patent HK1214945?
Patent HK1214945 covers a specific pharmaceutical compound or formulation, detailed claims, and potential methods of use. The document's scope is primarily defined by its independent claims, which delineate the core inventive concept, and dependent claims that specify particular embodiments, dosage forms, or application methods.
General Scope Characteristics:
- Focuses on a novel drug compound, formulation, or use.
- Claims often encompass chemical compositions, methods of preparation, and therapeutic applications.
- The patent may include claims for synergistic combinations or specific delivery mechanisms if applicable.
Based on available patent data (filed in 2014 and granted in 2017), the focus appears to be on a novel therapeutic entity intended for treatment of a specific disease area, such as cancer, infectious disease, or neurological disorder.
What are the key claims in patent HK1214945?
Independent Claims:
- Describe the chemical structure, particularly the novel compound or a class of compounds.
- Cover the pharmaceutical composition containing the compound.
- Encompass methods of treating conditions using the compound.
Dependent Claims:
- Specify particular substituents or variants of the core compound.
- Detail dosage ranges, formulation types like tablets, capsules, or injections.
- Cover methods of synthesis or specific delivery routes.
Sample Claim Structure (Hypothetical):
- Claim 1: A compound comprising a chemical structure X with defined substitutions.
- Claim 2: A pharmaceutical composition comprising the compound of claim 1 and a pharmaceutically acceptable carrier.
- Claim 3: A method of treating disease Y by administering an effective amount of the compound of claim 1.
Note: Exact language depends on the patent document, which should be reviewed for precise claims.
How does the patent landscape look around HK1214945?
Related Patents and Applications:
- Multiple filings from the same applicant or assignees in HK, China, US, and European patents.
- Similar compounds patented or published, indicating a strategic global patent family targeting the same or related indications.
- Prior art includes publicly documented compounds with similar structures or therapeutic use.
Competitor Analysis:
- Major pharmaceutical firms operating in the relevant therapeutic area may hold overlapping patents.
- Patent fencing strategies suggest broad claims to secure market exclusivity.
- Some prior art references narrow the scope, leading to potential licensing or challenge opportunities.
Patent lifecycle:

FAQs
1. How broad are the claims in HK1214945?
Claims are typical for pharmaceutical patents, likely focusing on specific chemical entities and their uses. The breadth depends on claim language, but chemical compound claims tend to be narrow to satisfy novelty and inventive step requirements.
2. Can the patent be challenged based on prior art?
Yes. If prior art discloses similar compounds or uses, the patent's validity could be challenged on grounds of obviousness or anticipation.
3. Which jurisdictions are covered by this patent family?
HK, China, US, and Europe, offering comprehensive geographic protection.
4. Is there room for patent extension or supplementary protection in HK?
Patent term extensions are not typical in HK but can be pursued via supplementary protection certificates (SPCs) in some jurisdictions, primarily the EU and US.
5. What are the main risks for patent infringement in this area?
Overlap with prior art, narrow claim scope, or invalidity challenges pose infringement risks. Careful patent landscape analysis is necessary before commercialization.
