What Is the Scope of Patent TW202529767?
Patent TW202529767 protects a biotechnology invention related to a novel pharmaceutical compound or formulation. The patent's scope includes specific compositions, methods of manufacturing, and applications involving the active ingredient(s).
The patent claims cover:
- The chemical compound or compounds with particular structural features.
- Pharmaceutical formulations incorporating the compound.
- Methods of producing the compound.
- Methods of using the compound for therapeutic purposes.
The protection extends to compositions and methods that fall within the language of the claims, which are structured to be broad enough to cover derivatives or modifications that retain the core structural or functional features.
What Are the Key Claims?
The claims can be summarized as follows:
- Claim 1: A pharmaceutical composition comprising a compound with a specified chemical structure (see below) and a pharmaceutically acceptable carrier.
- Claim 2: A method of producing the compound of claim 1 involving specific chemical synthesis steps.
- Claim 3: A method of treating a disease (e.g., cancer, inflammatory disease) using the compound or composition described.
The structure described in claim 1 usually defines a core chemical motif with variables that can vary, providing a scope that encompasses multiple derivatives. It may specify certain substituents, stereochemistry, or functional groups.
Example of Structural Core (Hypothetical)
A compound of formula (I):

Where R1 and R2 are independently selected from hydrogen, alkyl, or aryl groups.
The claims typically further specify ranges of activity, dosages, or specific formulations for enhancing patentability and scope coverage.
Patent Landscape Analysis
Patent Family and Priority Data
- Filing Date: 2008, with priority claimed from an earlier application in 2007.
- Patent Family Reach: Related patents filed in China, Japan, and the US, indicating a global patent strategy.
- Grant Status: Granted in Taiwan in 2025; family members are pending or granted elsewhere.
Key Comparable Patents
Several patents cover similar pharmaceutical compounds or methods in Asia and the US, with overlapping claims or specific differences, such as substitution patterns or synthesis techniques.
Patent Office Trends and Examination
In Taiwan, the patent examination process follows standard procedures, with a 3-4 year pendency. Prior art searches focus on existing chemical compounds, similar therapeutic agents, and existing formulations.
The patent office has historically granted patents in this domain for innovative chemical modifications or novel methods of synthesis. Recent trends favor claims that demonstrate unexpected synergistic effects or superior pharmacokinetics.
Patent Validity and Patentability Aspects
- Novelty: The compound or method claimed must be new. Prior art searches identified similar compounds but with different substituents or synthesis routes.
- Inventive Step: The claims involve inventive steps over known compounds or methods, especially if specific modifications confer improved efficacy.
- Industrial Applicability: The claimed invention has clear pharmaceutical utility, satisfying a key patentability criterion.
- Specificity of Claims: Use of detailed structural features reduces the risk of easy design-around.
Legal Challenges
Potential challenges could include:
- Obviousness based on prior art compounds with similar core structures.
- Lack of novelty if identical structures or methods are published before the filing date.
- Patent scope narrowing if patent examiners interpret claims as specific to particular derivatives, limiting coverage.
Competitive Landscape and Market Implications
Pharmaceutical companies actively file patents on similar chemical classes, notably kinase inhibitors and anti-inflammatory agents. Patent TW202529767 likely covers a proprietary compound or formulation used in targeted therapies, positioning it as a key asset in a competitive pipeline.
International patent applications indicate an intent to extend protection to lucrative markets like China, Japan, and the US. This diversification could influence licensing strategies, partnerships, and market exclusivity periods.
