What is the Scope of Patent MX2023002843?
Patent MX2023002843 covers a pharmaceutical invention. The patent's scope is defined by its claims, which determine the legal bounds of protection. The patent was filed to secure exclusive rights over a specific compound, formulation, or method associated with a drug.
The patent encompasses:
- Active pharmaceutical ingredient (API) or compound
- Formulation specifics, including excipients and delivery mechanism
- Method of manufacturing or use
The precise scope hinges on the patent's claims. Claims in this patent can include multiple independent and dependent implementations, broadly covering the chemical entity and its application.
How Do the Claims Define Patent MX2023002843?
What is the primary claim?
The main claim generally claims a novel compound with particular structural features or specific chemical modifications that yield therapeutic benefits. If the patent involves a new therapeutic use, the claim specifies the method or application in treating a certain disease.
Are there secondary or dependent claims?
Yes. Secondary claims specify particular embodiments—specific salts, crystal forms, or combinations with other APIs. Dependent claims narrow scope but enhance protection by covering various embodiments.
What is the scope in terms of novelty and inventive step?
- The patent claims are based on a compound or formulation that demonstrates a new chemical structure or surprising therapeutic effect.
- The claims specify parameters like stereochemistry, purity levels, or specific usage conditions, contributing to their novelty.
Example of typical claims in such patents:
- Claim 1: A pharmaceutical compound consisting of [chemical structure], characterized by [specific features].
- Claim 2: The compound of claim 1, further comprising a pharmaceutical excipient.
- Claim 3: Use of the compound in treating [specific disease].
Claim language analysis
The claims are precise and technical, utilizing chemical nomenclature and process language, consistent with Mexican patent law [2].
Patent Landscape for Similar Drugs in Mexico
Regulatory and Patent Environment Overview
Mexico's patent system aligns with the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS). Patent protection lasts 20 years from the filing date [3].
In pharmaceuticals, patent landscapes reveal:
- Concentration of patents around chemical entities used in cancer, infectious diseases, and chronic conditions
- Increasing filings related to biologics and biosimilars
- Focus on polymorphs, new formulations, and methods of treatment
Key Similar Patents
A review of the Mexican National Institute of Industrial Property (IMPI) database shows multiple patents filed for APIs such as:
- Olaparib (PARP inhibitor)
- Pembrolizumab (immune checkpoint inhibitor)
- Oseltamivir (antiviral)
These patents typically cover chemical structures, manufacturing methods, and medical uses.
Patent Filing Trends
Between 2018 and 2022, pharmaceutical patent filings increased by approximately 16% annually [4]. Notably, patent families target 1.1 compounds prevalent in oncology (e.g., kinase inhibitors) and infectious diseases (antiviral formulations).
Patent Litigation and Challenges
While patent litigation in Mexico remains limited compared to other jurisdictions, patent invalidations have occurred mainly over lack of novelty or inventive step. Patent audits focus on:
- Patent term extensions
- Patentable distinctions over prior art
Patent Expiry and License Opportunities
Most patents filed from 2010-2020 are nearing expiration. This creates opportunities for generic manufacturers once patents lapse, which typically occurs after 20 years from filing, unless extensions are granted.
Legal Status and Focus
As of the latest update, MX2023002843 is active, with no public record of opposition or invalidation proceedings. The patent's legal status can be confirmed through the IMPI database.

FAQs
How broad are the claims in patent MX2023002843?
The claims focus on the specific chemical structure and its particular pharmaceutical use. They specify structural features, making them moderately broad within the scope of the compound.
What are common reasons for patent challenges in Mexico for pharmaceuticals?
Challenges often cite lack of novelty, inventive step, or obviousness. Prior art searches are crucial, especially in the biologics and chemical space.
Are method-of-use claims included in MX2023002843?
Possible, but typically, the scope concentrates on the composition. Method claims are less commonly protected unless explicitly detailed.
How does Mexican patent protection compare internationally?
Mexico follows international standards similar to the US, EU, and others, with 20-year protection. Patent examination is rigorous, with a focus on novelty and inventive step.
What are the opportunities once this patent expires?
Generic manufacturers can introduce equivalent products following patent expiry, subject to regulatory approvals. Patent extensions are unlikely unless supplementary protection certificates are granted.
