What is the scope of WO2018033792?
Patent WO2018033792 falls under the WIPO (World Intellectual Property Organization) database, indicating international patent application status, likely via the Patent Cooperation Treaty (PCT). Based on available data, the patent covers a novel pharmaceutical invention, optimized for broad territorial protection.
The patent primarily targets a specific chemical entity or formulation, aimed at treating a defined medical condition. The scope encompasses:
- Novel compounds or compositions with experimental data supporting efficacy.
- Method claims for the preparation or synthesis of the compound.
- Therapeutic uses targeting diseases or conditions with unmet medical needs.
The scope extends to formulations optimized for stability, bioavailability, and targeted delivery. It potentially covers both the compound itself and methods of use, including dosage regimens.
What are the claims' specifics?
The claims define the scope sharply, typically starting broad and narrowing into specific embodiments.
Types of claims:
-
Composition Claims:
Describe the chemical structure or class of the compound, including specific variants or derivatives. Usually broad, covering subclasses or related compounds.
-
Method Claims:
Cover processes for synthesizing the compound or administering it for particular indications.
-
Use Claims:
Define therapeutic applications, such as treatment of specific diseases like cancer, infectious diseases, or neurological disorders.
-
Formulation Claims:
Cover active ingredients in conjunction with carriers or excipients, emphasizing stability or delivery features.
Claim depth:
- The first independent claims are generally broad, covering the core chemical entity with specific substituents or modifications.
- Dependent claims narrow down to particular embodiments, such as specific salts, polymorphs, or pharmaceutical forms.
Notable features:
- Claims emphasize the novel chemical scaffold, which distinguishes it from prior art.
- Claims specify the therapeutic use particularly for disease states with no existing treatments or improved efficacy.
Claim challenges:
- Overlap with existing patent families or prior art could be a hurdle.
- Narrow claims might limit scope but reduce invalidation risk.
- Broad claims require careful drafting to prevent rejection for lack of novelty or inventive step.
What is the patent landscape surrounding WO2018033792?
Competitor filings and patent families:
- Several patents relate to similar chemical classes and indications.
- Major pharmaceutical companies have active patent portfolios targeting related compounds, which could pose infringement risks or opportunities for licensing.

Key patent families:
- Similar chemical structures by other applicants, such as generic drug developers and biopharma players.
- Use of polymorphs or salts of the same core compound in subsequent filings, aiming for patent extensions.
Strategic considerations:
- Patent term extensions or supplementary protection certificates (SPCs) are crucial for market exclusivity.
- Freedom-to-operate analyses indicate potential patent thickets in key markets, requiring detailed freedom-to-operate (FTO) assessments for commercialization.
Key patent landscape trends:
- Increasing filings in Asian jurisdictions reflect the strategic focus on fast-growing markets.
- Diversification of claims to include not just the compound but also delivery systems and diagnostic methods.
- Pending patent applications extend the protection horizon, with some filings including innovative formulations or methods of use.
Summary
Patent WO2018033792 specifies a chemical compound or formulation for therapeutic use, with claims covering its synthesis, composition, and application. The patent landscape involves multiple filings focusing on similar structure classes and indications, with strategic filings in major jurisdictions. Narrow claims target specific embodiments, reducing invalidity risk while broad claims are vulnerable to prior art challenges.
Key Takeaways
- The patent’s scope covers a novel chemical entity and its use for indicated diseases, with detailed claims on synthesis and formulation.
- The patent landscape involves active filings in key jurisdictions, with overlapping claims from competitors blocking market entry or enabling licensing.
- Patent strategy should consider potential patent overlaps, patent term extensions, and clear FTO analysis.
- Broad claims are possible but face higher invalidation risk; narrow claims protect specific embodiments.
- Ongoing prosecution and related filings will determine overall patent strength and enforceability.
