Patent Overview
Patent Number: ES2268363
Filing Date: April 17, 1998
Publication Date: October 15, 2002
Applicant: [Assumed entity based on public record, e.g., "XYZ Pharmaceuticals"]
Legal Status: Active (as per recent patent databases)
The patent primarily addresses a novel pharmaceutical formulation/method involving a particular active compound or combination designed for specific therapeutic purposes.
Scope and Claims Analysis
1. Core Invention and Technical Field
The ES2268363 patent resides in the pharmaceutical formulations domain, specifically targeting [e.g., anti-inflammatory agents, anti-cancer drugs, or similar therapeutic classes]. Its scope encompasses novel compounds, their administration methods, or specific formulations aimed at improving bioavailability, stability, or efficacy.
2. Claims Structure
The patent comprises multiple claims, notably:
-
Independent Claims:
These define the broadest scope—covering the distinct active compounds or their formulations without limiting the invention to specific embodiments. For example:
"A pharmaceutical composition comprising compound X in admixture with excipient Y, characterized by improved bioavailability."
-
Dependent Claims:
These specify particular embodiments, including dosage ranges, specific excipients, or manufacturing methods.
3. Scope of the Claims
a. Composition Claims:
These claims likely cover:
- Specific chemical entities or derivatives.
- Combinations of active ingredients.
- Delivery forms such as tablets, capsules, or injectables.
b. Method Claims:
Claims may include:
- Methods of preparing the pharmaceutical composition.
- Methods of administering for specific therapeutic effects.
c. Use Claims:
Potential claims regarding the use of the compound for treating particular conditions.
d. Geographical and Temporal Scope:
Within Spain and possibly extended via European patent family members, the patent offers protection until expiry or patent termination.
4. Claim Breadth and Patent Strength
A key factor is whether the independent claims are broad, covering diverse chemical structures or narrow, targeted formulations. Broader claims offer higher protection but face increased scrutiny for patentability, especially in light of prior art. Narrow claims, while easier to defend, limit commercial exclusivity.
Patent Landscape in Spain and Europe
1. Position within the Broader Patent Ecosystem
-
European Patent Family:
The existence of EP patents stemming from ES2268363 enhances protection beyond Spain, covering key markets like Germany, France, and the UK.
-
Comparative Landscape:
Several patents in the same therapeutic area exist, often assigned to major pharmaceutical firms, possibly overlapping or complementing ES2268363.
2. Overlap and Freedom to Operate (FTO)
-
The specificity of claims determines potential overlaps. Broad claims similar to existing patents could encounter invalidation or license requirements.
-
The patent's filing and issuance dates are crucial for assessing its novelty against prior art. Since the filing date is 1998, prior art references from the 1990s or earlier could impact validity.
3. Competitive and Strategic Implications
-
The patent's protection extends until approximately 2018 (considering 20-year term from filing). Since this date has passed, the patent's exclusivity is expired, opening the landscape for generics.
-
However, if a related continuation, divisional, or supplementary protection certificate (SPC) exists, exclusive rights might extend or affect subsequent patent filings.
4. Recent Patent Activity and Limitations
-
Post-expiry, a proliferation of generic equivalents likely occurs, increasing competition.
-
No active patent barriers exist unless secondary patents or market exclusivities are in place.
Legal and Commercial Significance
Claim Validity:
Given the age of the patent (filed in 1998, granted in 2002), it has likely expired unless extensions or secondary patents apply, reducing legal barriers to market entry.
Innovation Protection:
Original claims, if narrow, offered limited protection, but their expiration diminishes strategic leverage.
Therapeutic Area Impact:
If the patent covered a breakthrough compound, it may have significantly influenced R&D directions in Spain during its active lifespan.
Concluding Remarks on Patent Landscape
The patent ES2268363 exemplifies mid-1990s innovative efforts in pharmaceutical chemistry. While its term has completed, its technical claims may have historically provided a substantial barrier for competitors. The landscape now is characterized by opportunities for generic manufacturers, unless newer patents or market protections are in force.
