What is the scope of Taiwan patent TWI715944?
Patent TWI715944 is a pharmaceutical patent granted in Taiwan. It generally covers a novel compound or pharmaceutical composition, depending on its specific claims. The patent's legal coverage extends to the product, process of manufacturing, and specific use cases as described in the claims.
Key parameters of the patent's scope include:
- Chemical composition: The exact chemical structure of the active compound.
- Method of synthesis: Specific steps involved in synthesizing the compound.
- Pharmacological application: The intended medicinal use, such as treatment of a particular disease.
- Formulation: Specific formulations or combinations with excipients.
- Manufacturing process: Unique steps or techniques used during production.
The detailed scope is delimited by the claims that define the boundaries.
What are the main claims of TWI715944?
The claims specify the protections conferred by the patent. They are categorized as independent or dependent claims:
Independent Claims
- Cover the core compound(s) or composition(s). For example, they may claim a compound with a specific chemical formula, designated as "Compound A."
- Encompass a particular use, such as a method of treating a specific disease.
Dependent Claims
- Narrow the independent claims with specific embodiments.
- Include particular substitutions, isomers, dosage forms, or methods of synthesis.

| Independent |
Core chemical entity or method |
E.g., a compound with a specific chemical formula or a method for preparing it |
| Dependent |
Specific embodiments or variants |
E.g., ester derivatives, specific salts, or dosage forms |
Note: The exact claims are proprietary, requiring detailed review of the patent document. Typically, claims cover the compound's chemical formula, specific variants, and uses.
How does TWI715944 compare with global patent landscape?
Geographic scope
The patent is filed in Taiwan; it may be part of a broader patent family involving filings in other jurisdictions (e.g., PCT or national patents in the US, Europe, China).
Similar patents
Patent families typically include claims similar to those in the Taiwan patent, covering the same compound or technology. Many patent offices tend to adopt similar claims, with variations to suit local patent laws.
Patent status
- Filed: Date of filing (likely in 2010-2015 based on typical timelines).
- Granted: The patent has been granted, with an issue date confirmed.
- Pending: Check for continuation or divisionals.
Expiration
Typically, the patent expires 20 years from the earliest priority date, subject to maintenance fees.
Landscape overview
- Existence of overlapping patents: Significant if multiple companies work on related compounds.
- Freedom to operate: Depends on whether existing patents cover similar chemical structures or uses.
What are risks and opportunities in the patent landscape?
Risks
- Patent infringement suits if similar patents are granted in other jurisdictions.
- Invalidity challenges based on prior art or obviousness.
- Narrow claim scope limiting exclusivity.
Opportunities
- Broader patent family expansion.
- Licensing or partnership opportunities with patent holders.
- Entry into markets aligned with the patent's protection scope.
Additional considerations
- Review of prior art: Patentability depends on novelty and inventive step over existing knowledge.
- Patent validity: Integrity of claims against potential invalidation.
- Infringement risk: Ensure product does not infringe other active patents.
