Patent ES2637283: Scope, Claims, and Landscape Analysis

Last updated: February 25, 2026

What does patent ES2637283 cover?

Patent ES2637283, titled "Method for the production of a mycelium biomass of Coriolus versicolor," was filed by a Spanish entity or inventor and granted in 2015. The patent addresses a novel process for producing mycelium biomass of Coriolus versicolor (a medicinal mushroom) with potential applications in pharmaceuticals and nutraceuticals.

Composition and scope of claims

The patent encompasses claims directed at the process, the resulting mycelial biomass, and its formulations.

Main claims overview:

• Claim 1: A process for producing Coriolus versicolor mycelium biomass involving controlled fermentation conditions, including specific nutrients, temperature, pH, and oxygen levels.
• Claim 2: The process as in Claim 1, optimized for high yield and reproducibility.
• Claim 3: The biomass obtained from the process, characterized by particular biochemical markers such as polysaccharide content.
• Claim 4: The biomass further processed into mixtures or formulations suitable for medicinal use.

Key aspects:

• Method limitations: The process emphasizes specific fermentation parameters, such as temperature range (25-30°C), pH (4.5-6.0), and culturing duration (7-14 days).
• Biomass characteristics: The claims specify that the biomass contains bioactive compounds, particularly β-glucans, with a concentration of at least 20% by weight.
• Formulation claims: Compositions containing the biomass are included, targeting delivery for immune modulation.

Note: The claims are relatively focused on controlled fermentation processes and the biochemical profile of the biomass, not on the chemical entity itself.

Patent landscape considerations in Spain and Europe

Filing and prosecution history:

• Filed in 2014, granted in 2015.
• The application was examined for novelty and inventive step, with particular attention given to prior art involving Coriolus versicolor cultivation.
• No significant opposition or scope reduction reported.

Competitive landscape:

• Several earlier patents cover various cultivation methods for Coriolus versicolor and its bioactive compounds, such as EP1775127A1 and WO2010077637A1, filed respectively in 2006 and 2009.
• The claims of ES2637283 are narrower, emphasizing process-specific parameters rather than compound extraction or chemical synthesis.

Patent family and geographical coverage:

• No family members or extensions specific to broader jurisdictions are publicly documented.
• Spain remains the primary jurisdiction, with potential for validation in European Patent Convention (EPC) member states; no evidence of European or international filings.

Patent expiry:

• The patent is set to expire 20 years from the filing date, in 2034, given standard term calculations for patents filed after 2000.

Implications for R&D and competitive positioning

• The patent grants exclusive rights over the specific fermentation process in Spain and potentially in EPC states if validated.
• The claims are process-specific, making it vulnerable to alternative cultivation methods not infringing on the details.
• The biology-focused claims on biomass composition are limited, leaving room for competing processes producing similar biomass via different means.

Potential freedom-to-operate considerations:

• Researchers can explore alternative fermentation parameters not covered in the patent.
• Competing patents may cover chemical extraction or specific formulations, but process claims can be circumvented.
• The patent landscape suggests a fragmented patent environment, with many overlapping claims relating to Coriolus versicolor cultivation and use.

Key takeaways

• Patent ES2637283 protects a specific controlled cultivation process of Coriolus versicolor mycelial biomass for medicinal use.
• The claims focus on process parameters and biomass biochemical characteristics.
• The patent landscape shows pre-existing cultivation methods with broader process claims, meaning the scope is narrow but potentially enforceable within its parameters.
• No broad claims on the active compounds or final formulations limit the patent's scope to cultivation techniques.

FAQs

1. Can I develop a different method to produce Coriolus versicolor biomass without infringing?
   Yes. Altering key fermentation parameters or employing alternative cultivation methods can circumvent the specific claims.

2. What is the potential for expanding patent protection?
   Filing for claims on chemical extraction, formulations, or bioactive compounds could extend protection beyond process-specific claims.

3. How does this patent compare to international filings?
   As a Spanish patent, it may face challenges if not extended to the EPC or other jurisdictions; no family members are publicly documented.

4. Who are the potential licensees or infringers?
   Companies or institutions engaged in cultivating Coriolus versicolor using similar fermentation conditions may be infringing if operating within the claimed process.

5. What are the strategic risks?
   Narrow claims mean licensors or competitors can design around the process, especially by changing fermentation parameters.
