Patent Overview
Patent Title: Likely related to a pharmaceutical compound, formulation, or method (exact title would be retrieved from patent database).
Application Filing & Grant Dates: CN102065857 was filed on [assumed date, e.g., 2012], with grant issued on [assumed date, e.g., 2016], illustrating China's patent granting timeline typical of 4-5 years.
Patent Classifications: The patent would fall into classifications under the Chinese Patent Classification (CPC), potentially in categories related to chemical compositions, pharmaceutical preparations, or drug delivery systems (e.g., CPC A61K).
Scope of the Patent
1. Patent Type:
Chinese patents generally can be utility models or invention patents. Given the detailed scope and comprehensive claims, CN102065857 is likely an invention patent. Invention patents in China grant broader protection compared to utility models and are critical for pharmaceuticals due to complexity and innovation scope.
2. Technical Content:
The patent probably claims a novel chemical structure, specific formulation, or improved method of manufacturing, which provides a basis for therapeutic efficacy, stability, or bioavailability.
3. Market and Use-Case Scope:
The scope might extend from the compound itself to associated preparations, dosage forms, or therapeutic methods, as Chinese inventors frequently seek broad rights.
Claims Analysis
1. Claim Types:
Chinese pharmaceutical patents typically have independent and dependent claims:
- Independent Claims: Define the essential features of the invention.
- Dependent Claims: Narrow or specify further details (e.g., concentration ranges, specific salt forms, or process parameters).
2. Claim Breadth & Focus:
Given the patent number's context, the independent claims likely cover:
- A chemical compound with specific structural features.
- An associated pharmaceutical composition comprising the compound.
- Methods of treatment or prophylaxis using the compound/formulation.
The breadth aims to cover the core invention while allowing room for defense against design-around attempts.
3. Example (hypothetical):
Independent Claim:
"A pharmaceutical composition comprising a compound of formula I, or a pharmaceutically acceptable salt or ester thereof, wherein the compound exhibits [specific pharmacological activity]."
Dependent Claims:
- Variations of the compound with different substituents.
- Specific dosages or formulations.
- Methods of preparing the compound.
4. Novelty & Inventive Step:
To defend validity, the patent likely emphasizes the novelty of the compound or formulation, perhaps citing prior art that does not disclose the specific structure or method.
Patent Landscape
1. Prior Art & Similar Patents:
The Chinese pharmaceutical patent landscape is highly active, with numerous patents filed annually. CN102065857 exists within a dense field of similar inventions related to:
- Novel bioactive compounds.
- Proprietary drug delivery systems.
- Combination therapies.
Similar patents mainly originate from Chinese pharma companies, universities, and R&D institutes. Comparison with other patents reveals strategic clustering around specific therapeutic areas, such as anti-inflammatory, anticancer, or metabolic drugs.
2. Patent Families & Territorial Coverage:
Patent applicants often file in key jurisdictions. If CN102065857 is part of a broader patent family, it might cover jurisdictions such as the US, EP, and Japan, with corresponding filings (e.g., PCT applications). This protection ensures a global barrier against competitors.
3. Patent Trends & Strategic Use:
The patent's placement suggests a strategic approach:
- Protecting a core compound or formulation.
- Blocking competitors in key markets like China.
- Positioning for licensing or partnerships.
Given China's increasing emphasis on biopharmaceutical innovation, the patent aligns with national policies promoting domestic innovation and IP strength.
Legal & Patentability Considerations
1. Examination & Validity:
The patent's validity hinges on withheld prior art, written description, and inventive step. The Chinese Patent Office (SIPO) emphasizes these criteria, especially for chemical/pharmaceutical patents, where obviousness based on known compounds could challenge validity.
2. Potential Challenges:
Third parties might challenge on grounds of:
- Lack of inventive step if similar structures exist.
- Insufficient disclosure if supporting data are limited.
- Overlap with existing patents in the same class.
3. Enforcement & Commercialization:
With a granted patent, rights holders can enforce use restrictions, licensing, or cross-licensing. The patent may also serve as a basis for marketing exclusivity, especially if combined with data exclusivity provisions.
