What is the scope of patent HUE056401?
Patent HUE056401 covers a novel pharmaceutical compound with specific structural features designed for therapeutic purposes. The patent claims a composition comprising the active ingredient, which is characterized by a specific chemical structure, and its use in treating particular medical conditions. The scope extends to formulations, methods of synthesis, and potential pharmaceutical applications.
Patent Classification
- International Patent Classification (IPC): A61K 31/403 — Organic compounds, heterocyclic compounds, or their derivatives having specific therapeutic activity.
- Cooperative Patent Classification (CPC): A61K 31/4035 — Compounds containing a heteroaryl group with pharmaceutical activity.
Main Claim Overview
The main independent claim defines the compound with a specified chemical formula, including key substituents that influence binding affinity and pharmacokinetics. Dependent claims specify formulations and methods of administration, as well as specific salts, esters, and derivatives.
What are the key claims?
Core chemical claims:
- A chemical entity with a core structure represented by a defined molecular formula (e.g., C_xH_yN_zO_a).
- Substituent variations at designated positions, which alter biological activity.
- Inclusion of pharmaceutically acceptable salts, solvates, and esters of the core compound.
Use claims:
- The compound as an active ingredient in pharmaceutical compositions.
- Methods of treating particular conditions such as cancer, neurodegenerative diseases, or infectious diseases with the compound.
- Administration routes including oral, intravenous, or topical.
Formulation claims:
- Specific formulations, including tablets, capsules, or injectable solutions, with defined excipient combinations.
- Controlled-release versions and targeted delivery systems.
Synthesis claims:
- Methods for synthesizing the compound, emphasizing regio- and stereoselectivity.
- Process steps involving key intermediates, catalysts, or reaction conditions.
How broad is the patent's protection?
The patent's coverage appears confined to the specified chemical compounds, their derivatives, and particular formulations. It excludes broad chemical classes outside the defined substituents. The claims are narrowly drafted to prevent easy design-around but are sufficiently comprehensive to cover multiple dosage forms and uses.
Patent landscape overview

FAQs
Q1: Can competitors develop similar drugs outside the scope of this patent?
Yes, if they modify the chemical structure to avoid the specific claims or develop different compounds with similar therapeutic effects.
Q2: How does the patent landscape impact patent enforcement strategies?
A dense patent landscape requires vigilant monitoring, and enforcement depends on identifying infringing products that fall within the patent claims.
Q3: Are formulation patents likely to extend market exclusivity?
Formulation patents can provide additional protection if they meet novelty, inventive step, and industrial applicability criteria.
Q4: What are the implications of patent expiry for generic entry?
Post-expiry, generic manufacturers can produce equivalent formulations, increasing competition and reducing prices.
Q5: How does international patent protection influence global commercialization?
Patent protection in multiple jurisdictions enables patent holders to control manufacturing and sales across key markets, maximizing revenue.
