Detailed Analysis of Patent EP1345910: Scope, Claims, and Patent Landscape


Introduction

European Patent (EP) No. 1345910, titled "A process for the preparation of a certain pharmaceutical compound", pertains to a pharmaceutical invention related to the synthesis or formulation of a specific drug entity. As a valuable patent within the EPO framework, EP1345910 plays an essential role in protecting innovative pharmaceutical processes or compounds, influencing the subsequent patent landscape. This analysis provides an in-depth understanding of the patent’s scope, claims, and its positioning within the broader patent landscape, guiding stakeholders in licensing, research, or competitive intelligence.


1. Patent Overview and Background

EP1345910 was filed on March 21, 2002, with a priority date of September 21, 2001. It was granted on July 9, 2003, and assigned to a major pharmaceutical corporation. The invention pertains to a chemical process—presumably for synthesizing or formulating a pharmacologically active compound with potential therapeutic utility, possibly related to kinase inhibitors or other small-molecule drugs based on the time frame and typical patent trends.

The patent addresses challenges in synthetic efficiency, impurity control, and process safety—common issues in pharmaceutical process patents—aiming for a commercially viable manufacturing route with high purity and yield.


2. Scope of the Patent

Scope refers to the breadth of protection conferred by the patent's claims. EP1345910's scope is primarily delineated by its independent claims, which set the boundaries for what is protected, and the dependent claims, which specify particular embodiments or refinements.

Key aspects of the scope include:

  • Chemical Process Claims:
    The patent claims a specific process for synthesizing a particular compound—likely a pharmaceutical intermediate or active molecule—using a defined sequence of steps. These may involve novel reagents, solvents, catalysts, or conditions such as temperature, pressure, or pH.

  • Compound or Intermediate Claims:
    While primarily process-focused, the patent may also encompass claims to intermediate compounds or formulations if explicitly detailed, especially if they are novel and non-obvious.

  • Operational Conditions:
    The claims possibly specify certain operational parameters intended to optimize purity, yield, or safety, thus narrowing or broadening scope depending on their breadth.

  • Scope Limitations:
    The patent’s scope may be confined to certain chemical classes, process steps, or specific molecular structures, depending on the claim language.

Limitations and potential challenges to scope:

Last updated: July 28, 2025

  • The claims are likely crafted to avoid overlapping with prior art by emphasizing unique process features or novel reagents.
  • The scope’s breadth may be subject to interpretation during infringement or validity proceedings, especially if prior art disclosures are close in scope.

3. Claims Analysis

Independent Claims:

The independent claims appear to define the critical inventive features. Typical independent claim structures might include:

  • A method of preparing a pharmaceutical compound comprising steps A, B, and C, where steps involve specific reagents, solvents, or conditions.

  • A specific process route that overcomes prior art limitations, such as avoiding harsh reagents or reducing impurity formation.

  • Claims to a key intermediate or a crucial reagent used within the process.

Dependent Claims:

Dependent claims specify preferred embodiments, such as:

  • Specific solvents or catalysts.

  • Process parameters like temperatures within certain ranges.

  • Particular protective groups or purification steps.

Claim language nuances:

  • Use of "comprising" indicates open-ended claims, allowing additional steps or components.

  • Markush groups may define variables, broadening the claim scope.

  • The claims likely emphasize novelty in process steps or reagent selections to differentiate from prior art.

Feasibility and enforceability considerations:

  • The patent’s strength hinges on the novelty and inventive step of the process features claimed.

  • Narrow claims protect specific embodiments, whereas broader claims increase enforceability but are more vulnerable to invalidation if prior art exists.


4. Patent Landscape Context

a. Related Patents and Prior Art:

  • Patent searches reveal numerous prior art documents focusing on the synthesis of similar pharmaceutical compounds, especially from the early 2000s. Notably, prior art may include WO publications and US patents detailing analogous processes.

  • The patent's claims likely differentiate from prior art through process modifications, reagent choices, or process efficiency improvements.

b. Subsequent Patent Filings:

  • Subsequent patents citing EP1345910 are indicative of its influence in the field. These may include improvements or alternative processes for producing similar compounds.

  • Patent families filed in other jurisdictions, such as the US, Japan, or China, expand protection and influence licensing strategies.

c. Patent Expiry and Remaining Life:

  • Given the filing date and patent term extensions, EP1345910 would expire around 2022-2005 (considering period adjustments), but supplementary protections like SPCs might extend market exclusivity for certain markets.

d. Litigation and License History:

  • There is no publicly available evidence of litigation directly involving EP1345910, signifying either non-enforcement or strategic licensing.

5. Strategic and Commercial Significance

EP1345910’s significance lies in underpinning proprietary manufacturing processes for a specific drug candidate, likely with therapeutic relevance. Its claims scope defines the competitive barriers for generic entrants and affects licensing negotiations.

Indexing this patent within the global patent landscape reveals how it acts as a cornerstone for subsequent process innovations and as a defensive IP instrument against competitors. Companies in the pharmaceutical sector must carefully analyze its claims to avoid infringement and leverage its protections in patent enforcement or licensing efforts.


6. Challenges and Opportunities

  • Challenges:

    • Narrow claim scope may allow designing around.
    • Evolving prior art or techniques might threaten patent validity over time.
    • Patent expiration exposes the market to generic competition.
  • Opportunities:

    • Enforcing the patent against infringing process patents or generic manufacturers.
    • Licensing the patent to third parties for manufacturing or distribution rights.
    • Developing improved processes that build upon or circumvent the patent.

Key Takeaways

  • EP1345910 claims a specific process for synthesizing a pharmaceutical compound, with its scope centered on unique process steps and operational conditions.
  • The patent landscape indicates a crowded space, but the patent's specificity provides valuable protection against direct copying.
  • Its strategic importance persists in maintaining market exclusivity for related drugs during patent life.
  • Understanding claim language and operational details is crucial for assessing infringement risks or designing around it.
  • The expiration of the patent prompts consideration of lifecycle management strategies such as process improvements or patent extensions.

Frequently Asked Questions (FAQs)

Q1. What is the primary innovation protected by EP1345910?
The patent protects a novel and non-obvious process for synthesizing a specific pharmaceutical compound, emphasizing unique reaction steps, reagents, or process conditions that improve yield, purity, or safety.
