The patent primarily relates to [the specific drug compound, formulation, or therapeutic method], offering novel insights that potentially protect [specific aspects such as composition, synthesis, delivery method, or therapeutic application].

Scope of Patent CN111825717

Technological Field

The patent pertains to [specify the drug class or therapeutic area, e.g., oncology, neurology, anti-inflammatory, etc.]. Its novelty resides in [describe innovation, such as a new compound, a unique synthesis process, a distinctive formulation, or a novel therapeutic method].

Coverage and Applicability

The scope encompasses:

  • Chemical Composition: Specific molecular structures with chemical formulaes, which could include [e.g., new derivatives, conjugates, or stereoisomers].
  • Preparation Method: Processes for synthesizing the active pharmaceutical ingredient (API), emphasizing [e.g., more efficient, environmentally friendly, or higher yield methods].
  • Pharmaceutical Formulation: Innovative delivery mechanisms or formulations that improve bioavailability, stability, or patient compliance.
  • Therapeutic Uses: Indications for the treatment of [disease or condition], possibly including method claims for administering the compound or composition.

Scope of Claims

The patent’s claims define the scope of legal protection as follows:

  • Independent Claims: These are broad and usually cover:

    • The chemical compound or compounds with specified structural features.
    • Specific synthesis processes.
    • Novel formulations or delivery systems.
    • Therapeutic methods involving the compound.
  • Dependent Claims: These narrow the protection, detailing specific embodiments:

    • Variations of the compound with different substituents.
    • Specific salt or ester forms.
    • Particular combinations with excipients or carriers.
    • Treatment protocols with dosage and frequency.

The broadest independent claim likely claims [general chemical structure or broad formulation], providing substantial coverage over similar compounds or compositions.

Claim Language and Scope Analysis

The claims are crafted to balance broad protection with enforceability:

  • Broad claims: Encompass a wide class of compounds or methods, shielding variations.
  • Specific claims: Cover particular embodiments for detailed enforcement.

This layered claim strategy enhances defensive robustness and future-proofing against design-arounds.

Patent Landscape

Prior Art Search and Patent Similarities

A search through existing patent databases (CNIPA, WIPO, EPO) reveals [number] patents related to [the same compound/therapeutic class]. Notable prior patents include:

  • CN[patent number]: Focused on [similar compound or method], with claims generally narrower, emphasizing specific structural features.
  • EP[patent number]: Covering [related chemical class or formulation] with broader claims but limited in scope regarding [specific process or use].
  • WO[patent number]: Disclosing [alternative synthesis method or compound] with overlapping structural characteristics.

CN111825717 distinguishes itself by [highlight novel aspects, such as a new synthetic route, improved stability, or expanded therapeutic claims].

Novelty and Inventive Step

Analysis indicates that:

  • The chemical structure claims are sufficiently innovative, differing from known compounds by [specific structural modifications].
  • The processing method demonstrates inventiveness through [e.g., a more efficient or safer synthesis route].
  • The therapeutic application claims are novel if [they target a new disease indication or method].

These elements contribute to its patentability and enforceability.
