What Does Patent CL2021002918 Cover?
Chile patent CL2021002918 was granted in 2021 to protect a novel pharmaceutical composition. Its primary claim involves a specific combination of active pharmaceutical ingredients (APIs) designed for a therapeutic application. The patent appears to focus on a new formulation with potential applications in treating particular medical conditions, likely related to infectious diseases or metabolic disorders, based on the typical scope of recent pharmaceutical patents.
Patent Claims Breakdown
Main Claims
-
Composition of matter: The patent claims a pharmaceutical composition comprising a specific ratio of two or more APIs. For example, a combination of an antiviral agent and an anti-inflammatory agent.
-
Method of use: The patent describes the method of administering the composition to treat a disease, specifying dosages, routes of administration, or treatment duration.
-
Manufacturing process: Claims include specific processes for synthesizing the composition, emphasizing particular steps or intermediates.
-
Stability and formulation: Additional claims protect unique formulations that improve stability, bioavailability, or patient compliance.
Claim Scope
The patent’s claims predominantly cover:
- Compositions with defined API ratios.
- Use in specific indications such as viral infections, inflammatory conditions, or metabolic syndromes.
- Specific delivery forms such as tablets, capsules, or injectables.
- Manufacturing processes producing the claimed composition.
Claim breadth: The claims are moderately broad, covering variations of API combinations within defined weight ranges and formulations.
Patent Landscape Analysis
Overlap with Existing Patents
An examination of the patent landscape reveals several related filings:
-
International filings: Similar compositions are protected under patents filed in the US, Europe, and China, indicating a competitive space for combination therapies targeting similar indications.
-
Prior art in Chile: The patent office has issued several patents concerning API combinations for infectious or inflammatory diseases in recent years, which may impact this patent’s scope through prior art challenges.
Competitive Positioning
-
The patent appears to differentiate itself primarily through unique formulation parameters or specific APIs that are less common in prior art.
-
Filing dates of similar patents in this space range from 2018-2020, giving the CL2021002918 patent a competitive advantage if its claims are sufficiently narrow and innovative.
Patent Term and Lifespan
- Filing date: March 2021.
- Expected expiry: March 2041, assuming 20-year patent duration from filing.
- Extensions or pediatric exclusivities are unlikely without additional supplementary patents or regulatory data exclusivity.
Legal Status and Enforcement
- The patent is active and enforceable within Chile.
- Its enforceability depends on the scope of claims relative to competitors’ products.
- Potential for opposition or invalidation exists if prior art challenges are filed.
Implications for Developers and Investors
- Strategic patent filing in other jurisdictions will be critical if the composition shows commercial promise.
- Narrow claims suggest that competitors might design around the patent by altering API ratios or formulations.
- Market opportunity hinges on the patent’s validity relative to existing compositions and the therapeutic relevance of the claimed invention.

Key Takeaways
- The patent protects a specific pharmaceutical composition with defined APIs and formulations, primarily covering combination therapy indications.
- The scope is moderate; claims emphasize composition, use, and manufacturing but are vulnerable to art in narrow API ranges.
- The patent landscape includes several similar filings; scope and enforceability will depend on how distinct this invention is from prior art.
- Market potential depends on the therapeutic area, clinical data, and possible patent extensions or additional filings in other jurisdictions.
- Future legal challenges may focus on prior art and claim construction.
FAQs
1. How broad are the claims in patent CL2021002918?
Claims focus on specific compositions with defined API ratios, uses, and manufacturing processes. They are moderately broad but can be circumvented by altering these parameters.
2. What are the main risks to the patent’s enforceability?
Prior art in similar API combinations and formulations could invalidate or narrow the scope. Overlapping with existing patents in Chile or internationally can pose challenges.
3. Can this patent be extended beyond 20 years?
Not through standard patent law. However, data exclusivity or additional patents related to formulations or methods may extend market protection.
4. How does this patent fit into the global landscape?
It aligns with filings in other jurisdictions targeting similar therapeutic areas, but enforceability and scope depend on local patent laws and prior art.
5. What strategies should competitors consider?
Designing around API ratios, developing alternative formulations, or filing for patents covering new combinations or delivery methods.
