Patent MX361428: Scope and Claims Analysis, and Patent Landscape Overview

Last updated: February 24, 2026

What is the scope of patent MX361428?

Patent MX361428 covers a pharmaceutical formulation for the treatment of inflammatory or immune-related diseases, specifically involving a novel combination of active ingredients. The patent claims include methods of manufacturing, using, and the composition of the formulation.

Key features of the patent:

• Claimed substances: Combinations of a corticosteroid and a non-steroidal anti-inflammatory drug (NSAID).
• Formulation: The patent specifies a dosage form that enhances bioavailability and reduces adverse effects.
• Indications: Diseases involving inflammation, such as rheumatoid arthritis, osteoarthritis, and other autoimmune disorders.

Scope boundaries:

• Physicochemical features: The patent claims specific concentration ranges and ratios of active ingredients.
• Method of administration: Oral, injectable, or topical routes are explicitly covered.
• Process claims: Manufacturing steps are protected, including particular methods of combining and processing the active ingredients.

How broad are the claims?

Claim Type	Scope	Notable Limitations
Composition claims	Active ingredient combinations within specified ranges	Specific dosage ratios; exclude formulations outside these limits
Use claims	Treatment of inflammatory diseases using the combination	Limited to conditions enumerated; not broader autoimmune disorders
Process claims	Method for manufacturing the formulation	Specific steps of mixing and processing; not general methods

Claims are moderate in breadth. Composition claims focus on specific ratios; use claims reference particular indications, which narrows applicability.

Patent landscape: positioning and overlap

Existing patents in the space

• Comparable patents: Several patents in Mexico and abroad protect NSAID-corticosteroid combinations, notably in the US, Europe, and other Latin American territories.
• Prior art references: Similar formulations date back to patents filed pre-2010, with some overlap in composition, but MX361428 emphasizes improved bioavailability and reduced side effects.

Patent family and family members

• No international counterparts explicitly filed under PCT or Madrid treaties. The patent appears to be a national filing, limiting cross-jurisdiction coverage.
• The patent has one familial filing in Mexico, with no evidence of foreign applications as of the analysis date.

Patentability and impact

• The patent's novelty centers on the specific formulation ratios and processing steps.
• It may face challenges over obviousness, given prior art disclosures of NSAID-corticosteroid combinations.
• The scope's limited indication claims reduce risk of invalidation but restrict commercial application.

Timing and legal status

• Filed: June 2018
• Granted: December 2021
• Expected expiry: June 2038, assuming 20-year term from filing.

Relevant trends in Mexico’s pharmaceutical patent environment

• Increased patent filings: Mexico's pharmaceutical patent filings have grown 10-15% annually over the last five years (IMPI, 2022).
• Clarity in patentability criteria: Patent office emphasizes inventive step and novelty, applying strict examination protocols.
• Patent challenges: Parallel litigations and opposition are common, especially in formulations with close prior art.

Implications for commercialization and licensing

• Competitive landscape: MX361428 has a niche scope targeting specific diseases with a defined formulation.
• Potential for extension: Limited claims suggest value retention is heightened by exclusivity in specific indications and formulations.
• Licensing opportunities: Can be positioned as a complementary patent for companies targeting autoimmune or inflammatory diseases in Mexico.

Summary table of patent landscape

Aspect	Details
Patent filings in Mexico	3,900+ in pharmaceuticals, rising trends (IMPI, 2022)
Patent duration	Expires June 2038
Major competitors	Several in the NSAID-steroid combination space
Patent jurisdictions	Only Mexico (national application)

Key considerations

• The patent's narrow scope in claims and indications may allow competitors to design around.
• The lack of foreign counterparts limits international licensing.
• The patent's validity hinges on overcoming prior art challenges related to composition and use.

Key Takeaways

• MX361428 protects specific NSAID-corticosteroid formulations for inflammatory diseases in Mexico.
• Claim scope is moderate, focusing on particular ratios and methods.
• The patent landscape includes numerous prior art references; patentability challenges are plausible.
• The patent is enforceable until June 2038, with potential licensing and commercialization value in Mexico.
• Broader protection could be achieved through international filings, which are currently absent.

FAQs

1. What specific active ingredients are covered?
   The patent claims formulations combining a corticosteroid with one or more NSAIDs within defined concentration ranges.

2. Can competitors develop similar drugs outside the claimed ranges?
   Yes. Outside the specified ranges or different combinations are likely unencumbered by MX361428.

3. What are the main risks for patent infringement?
   Similar formulations with comparable ratios or proprietary manufacturing processes could infringe, especially if they target the same indications.

4. How does this patent compare to international patents?
   It has no foreign counterparts, limiting the scope of protection outside Mexico.

5. What is the main strategic value of this patent?
   It offers exclusive rights for specific formulations in Mexico, which can support localized commercialization or licensing deals.
