Patent Overview
Patent Number: TWI639425
Applicant/Assignee: Typically, such patents are filed by innovative pharmaceutical companies or research institutions, though specific ownership details should be confirmed from official patent records.
Filing Date: Exact date pending, but such patents are often filed within 2020-2022, thematic with emerging drug innovations.
Patent Status: Pending, granted, or under examination status should be confirmed via the Taiwan Intellectual Property Office (TIPO).
The patent appears to relate to a novel compound, formulation, or method relevant to drug therapy—likely within a therapeutic area such as oncology, neurology, infectious diseases, or metabolic disorders, based on current patent trends.
Scope and Claims Analysis
Claim Structure
Claims define the legal scope of a patent — the boundary of the inventor’s exclusive rights. They are dissected into independent and dependent types:
- Independent Claims: These specify the core invention, usually covering a novel compound, formulation, or method.
- Dependent Claims: These narrow the scope, adding specific embodiments, such as particular dosage forms, combinations, or manufacturing processes.
Key Aspects of Claims
Without access to the detailed claim language (which is necessary for precise analysis), general assessment assumes the patent covers:
- Novel Chemical Entities or Derivatives: Often, modern patents focus on structurally unique molecules with improved efficacy or safety profiles. Such claims stipulate the chemical structure, stereochemistry, or molecular modifications.
- Pharmaceutical Compositions: Claims might include specific formulations—such as sustained-release forms, combination therapies, or targeted delivery systems.
- Use Claims: These specify the therapeutic application, e.g., treatment of specific diseases or conditions.
- Method Claims: Claims might encompass manufacturing or treatment methods, covering steps or protocols for administering the compound.
Claim Strengths and Limitations
- Novelty & Inventiveness: The patent's strength hinges on the uniqueness of the chemical structure or method, with prior art assessments essential to ascertain overlap.
- Claim Breadth: Broad claims covering a class of compounds or multiple uses afford wider protection but are more vulnerable to invalidation if overly encompassing.
- Specificity: Narrow claims tend to be more defensible but provide limited scope.
Potential Claim Challenges
- Prior Art Compatibility: Existing patents or publications in the chemical or pharmaceutical domain may scrutinize claim novelty.
- Anticipation and Obviousness: Claims claiming compounds similar to known drugs with minor modifications could face validity issues.
Patent Landscape and Competitive Environment
Global Patent Environment
-
Patent Families in Major Jurisdictions: It is typical for innovative drugs to be protected across multiple key markets—U.S., Europe, China, Japan, and Korea—alongside Taiwan. Cross-patent family analysis reveals strategic global protection.

Comparable Patents: Similar patents, perhaps with chemical analogs or related therapeutic methods, chart the competitive space. A patent landscape analysis (via PatentScope, WIPO, or commercial patent analytics tools) shows all relevant patents and their filing timelines.
Major Players and Patent Assignees
- Industry Peers: Global pharmaceutical companies or biotech firms likely operate in this space, directing patent filings for similar compounds.
- Research Institutions: Universities or governmental agencies may also hold patents related to the same chemical class or therapeutic method.
Technology Trends and Innovation Focus
- Innovation Hotspots: Patents in this space tend to focus on improving bioavailability, reducing side effects, or targeting resistant disease strains.
- IP Strategies: Companies often file multiple patents covering chemical modifications, formulations, methods, and uses to build a comprehensive patent thicket around their assets.
Legal Status and Expiry Timeline
- Patents typically last 20 years from the filing date; thus, TWI639425’s remaining patent term influences its market exclusivity.
- Pending or granted status impacts current commercialization strategies and market entry timelines.
Implications for Stakeholders
- Pharmaceutical Companies: The scope indicates potential licensing opportunities, infringement risks, or freedom-to-operate considerations.
- Research Institutions: Understanding claim boundaries aids in designing around existing patents.
- Legal & Patent Professionals: A thorough review involves examining prosecution histories, cited references, and potential oppositions.

FAQs
-
What is the significance of claim scope in patent validity?
The scope determines the legal protection boundaries. Broader claims can secure extensive rights but are more susceptible to invalidation if challenged on the grounds of lack of novelty or obviousness.
-
How does the patent landscape influence a company's R&D decisions?
It guides the development path by highlighting existing protections and gaps, enabling companies to innovate around existing patents or strengthen their own IP portfolio.
-
What strategies do companies use to extend patent life or protection?
They often file secondary or dependent patents for improvements, formulations, or methods, creating patent families for extended market exclusivity.
-
How can patent comparison help prevent infringement?
Analyzing similar patents ensures new compounds or formulations do not infringe existing rights, avoiding costly legal disputes.
-
Why is regional patent protection critical for pharmaceuticals?
Different markets have distinct legal frameworks; securing patent rights in key jurisdictions ensures comprehensive market protection and maximizes commercial value.
