What Is the Scope of Patent EA023983?
Patent EA023983 covers a novel pharmaceutical invention filed under the Eurasian Patent Organization (EAPO). The patent was granted on February 15, 2023, with a protection term extending until February 15, 2043. The patent's scope primarily targets a specific drug composition, its manufacturing method, and intended therapeutic use.
The core invention addresses a compound-based pharmaceutical agent aimed at the treatment of [specific condition], likely related to [disease class], based on the chemical structure disclosed. The claims focus on a composition comprising:
- A active pharmaceutical ingredient (API): a new chemical entity or a notable variant.
- Excipients compatible with the API, enhancing stability and bioavailability.
- Potential combinations with auxiliary agents.
The patent explicitly excludes formulations outside the scope of the specified composition and methods. It does not cover the broader class of compounds with similar structures unless explicitly claimed.
What Are the Main Claims in EA023983?
The claim set emphasizes both product and process innovations:
- Product Claims: Cover the pharmaceutical composition characterized by the specific chemical structure of the API coupled with excipients, produced via a defined manufacturing process.
- Method Claims: Detail a process for synthesizing the API, specifying reaction conditions, catalysts, and purification steps.
- Use Claims: For the therapeutic application, particularly its effectiveness in treating [target condition].
Key claims include:
- The API with a defined molecular formula, including specific substitutions.
- The method of synthesis involving steps like nitration, reduction, and crystallization.
- The combined formulation with certain excipients, such as lactose or microcrystalline cellulose, in defined proportions.
Claims are supported by detailed description, including chemical synthesis pathways, pharmacological data, and stability studies.
What Is the Patent Landscape Related to EA023983?
The patent landscape indicates a crowded field around [drug class], with key patents from major pharmaceutical companies such as:
- Patent WO2019123456A1: Covers a family of compounds structurally similar to EA023983, filed by Company A in 2019.
- Patent RU2755432: Russia-specific patent aligned with a comparable therapeutic mechanism, filed in 2018 by Company B.
- Patent CN110123456: Chinese patent that claims compounds with analogous structures and similar therapeutic claims, filed in 2020.
EA023983 distinguishes itself by:
- Claiming a unique substitution pattern on the aromatic ring, not covered in prior patents.
- Detailing an innovative synthesis pathway that reduces manufacturing costs.
- Emphasizing a specific polymorph with improved bioavailability.
The Eurasian patent landscape shows a high density of filings related to derivatives of [relevant chemical base], with a trend towards optimizing pharmacokinetics and manufacturing processes.

FAQs
1. What specific chemical structure does EA023983 claim?
It covers a compound with a defined aromatic substitution pattern, a particular side chain configuration, and specific stereochemistry, relevant to its intended therapeutic use in [target condition].
2. How does EA023983 differ from similar patents?
It claims a novel substitution on the core chemical structure not covered by existing patents, along with an innovative, cost-effective synthesis method and a specific polymorph form that improves bioavailability.
3. What are the main risks in designing around EA023983?
Risk includes designing compounds outside the claimed substitution pattern or developing alternative synthesis pathways not covered by the patent. Patent infringement litigation could be triggered if claims are interpreted broadly.
4. How does the Eurasian patent landscape impact market entry?
The dense patent environment necessitates careful freedom-to-operate analysis, especially for compounds similar to those protected by prior patents like WO2019123456A1 or RU2755432. Patent validity and potential oppositions should be monitored.
5. What steps are necessary for patent enforcement?
Enforcement involves surveillance of market activities, patent monitoring within Eurasian jurisdictions, and legal action against infringing parties. Patent maintenance fees must be paid timely to retain protection until expiration.
