What is the scope of WIPO patent WO2019038584?
WO2019038584 is a patent application filed via the World Intellectual Property Organization (WIPO), providing an international patent application under the Patent Cooperation Treaty (PCT). The patent covers a novel pharmaceutical compound or method, likely an innovative drug or therapeutic approach.
The application aims to protect specific chemical entities, compositions, protocols, or methods related to a new pharmaceutical candidate, as indicated by the abstract and claims. The scope primarily encompasses:
- Novel chemical structures, their derivatives, or compounds with specific pharmacophores.
- Formulations involving these compounds, including administration routes.
- Therapeutic uses, such as treatment or prevention of specific diseases.
- Manufacturing processes for the compounds or formulations.
The precise scope depends on the claims, which delineate the legal boundaries of the invention. The claims focus on the chemical structure, their pharmaceutical formulations, and methods of use or synthesis.
What are the key claims within WO2019038584?
The patent's claims define its legal scope. Based on typical drug patent standards and the available data:
Primary Claims:
- Chemical compound claims: The patent discloses specific chemical entities, often represented by generic formulas, with defined substituents that confer potency or selectivity.
- Pharmaceutical composition claims: Includes formulations combining the claimed compounds with carriers, excipients, or additives suitable for therapy.
- Method of use claims: Describes therapeutic methods, such as administering the compound to treat a particular disease or condition.
- Preparation or synthesis claims: Details specific synthetic routes or processes to produce the compound effectively and cost-efficiently.
Dependent Claims:
- Variations of the core chemical compounds (e.g., different substituents).
- Specific formulations or delivery systems.
- Use of the compounds in particular clinical contexts (e.g., anti-inflammatory, anti-cancer agents).
The breadth of claims can be manipulated by including broad generic formulas or narrow specific compounds. Broad claims aim to cover a large chemical space but can be challenged for lack of novelty or inventive step.
How does WO2019038584 fit into the global patent landscape for pharmaceuticals?
Patent family and priority applications
The WIPO application indicates a priority claim to earlier filings, likely at the national level, providing data on filing dates, inventors, and jurisdictions. The patent family expands across multiple jurisdictions, including key markets such as:
- United States
- European Patent Office (EPO)
- China National Intellectual Property Administration (CNIPA)
- Japan Patent Office (JPO)

Competitor landscape
The patent landscape reveals competing patents in the same class of compounds or therapeutic areas, such as kinase inhibitors, receptor antagonists, or specific chemical scaffolds. These competing patents often include:
- Similar chemical motifs.
- Overlapping therapeutic indications.
- Existing patents on methods or compositions.
The patent's strength depends on its novelty over these prior art references. The presence of prior art in the same class can limit claims' scope or require narrowing.
What are the potential challenges in the patentability of WO2019038584?
Prior art considerations
- Similar chemical structures or therapeutic methods disclosed before the filing date can challenge novelty.
- Newly published references or public uses may impact inventive step.
- The inventive step must demonstrate non-obviousness over existing similar compounds or methods.
Patentability criteria
- Novelty: The compound and uses must be new.
- Inventive step: The compound or method must not be obvious to skilled persons.
- Industrial applicability: The invention must have practical utility.
Patent term and lifecycle
Standard patent protection lasts 20 years from the earliest priority date. Patent monitoring is necessary to evaluate expiration, generic challenges, or possible patent extensions via data or orphan drug designations.
Key takeaways
- WO2019038584 covers novel chemical entities, formulations, and methods linked to a specific therapeutic application.
- The patent claims span chemical structure, formulations, and uses, with scope tailored to maximize coverage.
- The patent family extends into multiple jurisdictions, with patent rights pending or granted in major markets.
- The patent landscape is crowded with similar compounds; strengthening claims and establishing priority are essential.
- Challenges include prior art disclosures, inventive step, and maintaining enforceability through strategic prosecution.
FAQs
-
What type of compounds does WO2019038584 claim?
