EP2754463 pertains to a method for producing a recombinant protein—specifically, a process that enhances output efficiency and ensures product quality. The patent’s claims target biotechnological processes, emphasizing recombinant DNA technology, cell culture, and purification steps, rather than a specific molecule or therapeutic indication.
2. Geographic Coverage and Jurisdiction
The patent is validated across multiple European countries via the European Patent Convention (EPC), affording broad territorial protection. The scope extends jurisdictionally across key pharmaceutical markets such as Germany, France, UK, and other EPC member states.
3. Patent Term and Expiry

Detailed Analysis of Claims
1. Claim Structure Overview
EP2754463 comprises independent and dependent claims, outlining comprehensive steps in the protein production process. The independent claims primarily describe methods involving specific genetic constructs, host cells, cultivation conditions, and purification techniques.
2. Key Elements of the Claims
-
Genetic Constructs: The claims specify recombinant DNA sequences encoding the target protein, with particular promoter, enhancer, and signal sequence elements to optimize expression.
-
Host Cell Lines: The claims cover host cells (e.g., CHO, HEK293) engineered for high-yield protein expression, with features like stable integration or inducible expression systems.
-
Cultivation Conditions: Parameters such as nutrient composition, temperature shifts, and bioreactor parameters are integral to claim scope, aiming to optimize yield and stability.
-
Purification Process: The claims detail sequential chromatography steps, filtration, and formulation protocols designed for high purity and bioactivity of the protein product.
-
Innovative Aspects: The claims emphasize the combination of genetic and cultivation innovations to improve protein yield and activity, safeguarding incremental advancements over prior art.
3. Claim Limitations and Scope
The claims are sufficiently broad to cover various recombinant proteins produced via the specified method but are restricted to the specific process steps and sequences disclosed. This precise delineation limits infringement but offers room for alternative methods or constructs outside the claims' scope.
Patent Landscape and Prior Art
1. Landscape Overview
The patent landscape for biopharmaceutical production methods is highly active, with multiple patents focusing on cell line engineering, bioprocessing metrics, and purification techniques. EP2754463 fits within this milieu—specifically among patents targeting improved bioprocesses for recombinant protein manufacture.
2. Related Patents and Prior Art
Numerous patents predate EP2754463, such as US patents on similar host cell modifications (e.g., US patent 7,814,602), and process improvements (e.g., US patent 8,123,006). The inventive step in EP2754463 hinges on specific combinations of genetic, culture, and purification steps that distinguish it from prior art.
3. Patent Examination and Challenges
During prosecution, the applicant likely navigated prior art rejections by emphasizing unique process steps and their synergistic effects. Competitors might challenge the validity by citing earlier cell line modifications or purification techniques but would need to demonstrate that EP2754463's claimed methods are novel and inventive.
4. Competitor and License Landscape
In the biotechnology sector, competing patents typically cluster around:
- Host cell line engineering
- Optimized bioreactor processes
- Product purification innovations
EP2754463’s claims intersect with these areas. Licensing agreements and patent thickets are common, requiring thorough due diligence before process commercialization.
Implications for Industry Stakeholders
1. For Innovators
The patent provides protection for biotech firms seeking to develop similar production processes, particularly those emphasizing process combinations for yield and quality improvements. Careful design around—altering specific process steps or genetic elements—can circumvent infringement.
2. For Generic Manufacturers and Biosimilar Developers
The scope delineates critical process steps that, if modified, could avoid infringement. Understanding the patent’s breadth aids in designing non-infringing manufacturing workflows, especially given the patent's focus on specific sequence combinations and process parameters.
3. For Patent Holders and Licensing Entities
The patent’s strategic position grants a competitive advantage in biopharmaceutical manufacturing. FMCG, biotechs, and pharmas should monitor licensing opportunities and patent expiry dates to plan process development timelines accordingly.
Regulatory and Commercial Aspects
While patents focus on process innovations, their commercial value is tied to regulatory approvals and the ability to produce high-quality biopharmaceuticals at scale. Process patents like EP2754463 underpin the manufacturing basis for biosimilars and novel biologics.
