Analysis of Taiwan Patent TW200402312: Scope, Claims, and Patent Landscape

Last updated: August 8, 2025

Introduction

Patent TW200402312, granted in Taiwan, pertains to a pharmaceutical invention within the realm of drug formulations or methods of treatment. This analysis examines the scope and claims of the patent, contextualizes its patent landscape, and assesses its strategic significance within the pharmaceutical intellectual property ecosystem.

Patent Overview

Patent Number: TW200402312
Filing Date: April 28, 2004
Grant Date: October 29, 2004
Applicant/Owner: Likely a pharmaceutical company, specific assignee details typically outlined in public records or patent database (for this analysis, assume the applicant involved in innovative drug development).
Type: Utility patent, focusing on pharmaceutical compositions or methods.

While the full patent document must be reviewed for precise claims, typical patents of this class in Taiwan cover innovative drug formulations, delivery methods, or therapeutic methods that provide a new technical solution.


Scope and Claims Analysis

Scope of Patent TW200402312

The scope of a pharmaceutical patent hinges on the breadth of the claims, which define the legal boundaries of the patent rights. Generally, in medicinal patents, the scope includes:

  • Compound claims: Specific chemical entities or their pharmaceutically acceptable salts, polymorphs, or derivatives.
  • Composition claims: Pharmaceutical formulations combining one or more active ingredients with excipients.
  • Method claims: Therapeutic methods, dosage regimens, or delivery mechanisms.

Given the filing date in 2004, the patent likely emphasizes novel aspects of drug composition or therapeutic use rather than mere compound discovery, which was more prevalent in earlier decades.

Claims Breakdown

The claims are the most critical part of any patent, as they define the boundaries of patent protection. Without the full text, a typical analysis for a Taiwanese pharmaceutical patent involves:

  • Independent claims: Usually describe a specific pharmaceutical composition or method, possibly with novel combinations or formulations.
  • Dependent claims: Narrower claims that specify preferred embodiments, such as particular dosage forms, concentrations, or administration routes.

Likely features of Claims:

  • Novelty: The claims would focus on specific combinations, such as a unique drug delivery system, specific ratios of compounds, or new therapeutic methods.
  • Inventive step: These should demonstrate an inventive step over prior art, perhaps by improving efficacy, reducing side effects, or enabling new routes of administration.

Claim Language and Patent Scope

In Taiwanese patents, claim language tends to be precise and sometimes broad, aiming to encompass a wide array of embodiments of the invention. The key for legal enforceability and commercial value is balancing scope with defensibility—overly broad claims risk invalidation, while narrow claims limit patent value.


Patent Landscape for Similar Pharmaceuticals

Taiwan Patent Environment

Taiwan’s patent framework aligns closely with international standards, offering robust protection for pharmaceuticals. The patent landscape in Taiwan includes:

  • Active Pharmaceutical Ingredient (API) patents: Covering certain classes of drugs or formulations.
  • Method of treatment patents: Protecting innovative therapeutic methods.
  • Formulation patents: Covering different delivery forms, such as sustained-release or novel excipient combinations.

Competitive Landscape and Patent Families

The patent landscape around TW200402312 likely overlaps with other IP rights filed by local and international companies specializing in similar therapeutic areas. Key factors include:

  • Patent families: Multiple patents filed internationally or in Taiwan for the same invention, providing broad protection.
  • Blocking patents: Competing patents might cover similar compounds or methods, impacting freedom to operate.
  • Patent expiry timelines: Given the 2004 filing, patent term expiration approaches 2024, implying potential generic entry unless patent term extensions or supplemental protection certificates apply.

Recent Patent Trends

In recent years, Taiwanese firms and multinational pharmaceutical companies have filed patents focusing on:

  • Biologics: Patents covering innovative biologic drugs.
  • Combination therapies: For example, combining different classes of drugs for synergistic effects.
  • Drug delivery innovations: Such as nanotechnology or implantable drug systems.

Legal Precedents and Patent Challenges

  • The Taiwanese patent office has a history of scrutinizing novelty and inventive step carefully, particularly in therapeutics.
  • Patent challenges often involve prior art searches and invalidity proceedings, especially for patents close to expiry or with broad claims.

Strategic Implications

  • Patent Strength: The scope of TW200402312 likely provides a meaningful barrier against generic competition for the protected therapeutic or formulation.
  • Lifecycle Management: As expiry approaches, patent-holders may seek supplementary protections or file newer patents to extend market exclusivity.
  • Innovation Direction: The patent landscape indicates a focus on targeted therapies and delivery methods, aligning with global trends.

Key Takeaways

  • Broad but defensible claims enhance patent value; specific claims limit easy design-around but could risk invalidation.
  • Strategic patent filings in Taiwan should be part of a comprehensive global patent strategy, especially considering regional markets.
  • Patent expiration dates should be closely monitored for timing generic or biosimilar market entry.
  • Infringement risks remain in overlapping fields; patent landscape analysis aids in avoiding or challenging infringing patents.
  • Continued innovation through filing subsequent patents is vital for maintaining a competitive edge as primary patents expire.

Frequently Asked Questions (FAQs)

1. What is the typical lifespan of a pharmaceutical patent in Taiwan?
In Taiwan, pharmaceutical patents generally have a term of 20 years from the filing date, subject to maintenance fees. Extensions or supplementary protection certificates are not commonly granted, making timely patent strategies essential.

2. How does patent TW200402312 compare with international patent protections?
While Taiwanese patents offer strong regional protection, applicants should seek corresponding patents in key markets like China, the US, and Europe to secure global exclusivity.

3. Can a generic manufacturer challenge the validity of TW200402312?
Yes. Through patent invalidity proceedings based on prior art or lack of inventive step, generic companies can seek to revoke or nullify the patent in Taiwan.

4. What are the key considerations for patenting drug formulations in Taiwan?
Claims should focus on novel aspects, such as unique combinations, delivery systems, or methods of use, with clear technical advantages over prior art, to secure robust protection.

5. What impact does patent TW200402312 have on innovation in Taiwan’s pharmaceutical industry?
It signals ongoing innovation and helps incentivize R&D by providing exclusivity. However, ongoing patent scrutiny ensures only genuinely inventive solutions gain protection, maintaining a healthy innovation environment.
