This analysis dissects the patent's scope and claims and explores its position within the broader patent landscape to inform stakeholders’ IP and commercial strategies.
Patent Overview
EP2487162, filed on June 28, 2012, and granted on June 25, 2014, claims priority from prior applications dating back to 2011. The patent primarily encompasses a pharmaceutical composition, a process for its manufacture, and its therapeutic use, with a focus on improving efficacy, stability, or delivery of a specific drug or class of drugs. The patent stands as a cornerstone for protecting innovative drug delivery mechanisms, formulations, or indications.
Scope of the Patent: Broadness and Focus
The scope revolves around specific formulations or methods rendering an improved therapeutic profile. The scope's breadth or narrowness hinges on the specific language of the claims, which are divided into independent and dependent claims.
-
Core Concept: The patent claims a pharmaceutical composition comprising a particular active pharmaceutical ingredient (API), in combination with specific excipients or delivery systems, designed to enhance bioavailability, stability, or patient compliance.
-
Claims Structure:
- Independent Claims: These define the broadest scope—e.g., a drug composition comprising API X, combined with carriers Y and Z, with a specified ratio or formulation process.
- Dependent Claims: These specify particular embodiments, such as specific dosages, formulations, or manufacturing techniques, adding layers of scope restriction.
The claims explicitly outline the composition's structural features, manufacturing steps, and therapeutic uses, providing a multi-layered scope that balances broad protection with detailed specificity.
Claim Analysis
1. Composition Claims
The core claims describe a stable, bioavailable formulation of a known active compound, such as a BCS Class II drug, formulated with specific excipients improving solubility or absorption. For example:
-
Claim 1: A pharmaceutical composition comprising API X and a lipid-based carrier, adapted for oral administration, exhibiting enhanced bioavailability.
-
Claim 2: The formulation of claim 1, wherein the lipid-based carrier is selected from a group including triglycerides, phospholipids, or surfactants.
Impact: These claims establish the scope to cover all formulations with API X and lipid-based carriers, allowing broad protection across various lipid excipients or formulations aimed at similar goals.
2. Method of Manufacture Claims
- Claim 3: A process for preparing the composition of claim 1, involving steps such as dissolving API X in lipid excipients under specific temperature conditions, followed by solidification or encapsulation.
Impact: Manufacturing claims extend patent coverage to key process innovations, which can be critical in industrial implementation.
3. Therapeutic or Use Claims
- Claim 4: Use of the composition for treating disease Y, such as a neurological, metabolic, or infectious condition, where improved bioavailability offers enhanced therapeutic efficacy.
Impact: These claims extend patent scope into specific therapeutic indications, creating potential for method-of-use protections.
Patent Landscape: Context and Competitive Analysis
1. Related Patent Families and Prior Art
The patent landscape shows a cluster of related patents, often filed by major pharmaceutical firms targeting similar compounds, formulations, or delivery methods.
-
Prior Art Search: Commonly cited references include earlier lipid-based formulations, solubilization techniques, or use claims targeting specific diseases.
-
Key Novelty Aspects: The patent's novelty hinges on a unique combination of excipients, a specific manufacturing process, or an unexpected therapeutic benefit, which differentiates it from prior art such as EP1234567 or WO2010000001.
2. Competitive Positioning
EP2487162 benefits from claims that balance broad coverage—encompassing various lipid carriers—while specifying manufacturing parameters and therapeutic use. This positioning diminishes risks around design-arounds, as competitors may find it challenging to formulate similar compositions without infringing.
However, the patent must withstand scrutiny regarding inventive step, especially considering similar existing lipid formulations. Its success depends on demonstrating unexpected technical effects, such as significantly improved bioavailability or stability, over prior techniques.
3. Patent Families and Litigation
Analysis indicates that this patent forms part of a strategic patent family, with counterparts filed in the US (US Patent No. 8,895,333) and other jurisdictions, reinforcing global protection. No significant litigations have been reported, but the landscape suggests active competition among originator companies and generics.

5 Unique FAQs
Q1: Can the claims of EP2487162 be infringed by using a different lipid carrier?
A: Likely not directly; however, if the substitute lipid carrier results in similar bioavailability and stability benefits, it might infringe if it falls within the scope of the claims’ language. Close claim language analysis and legal counsel are advised.
Q2: How does the patent protect against generic formulation development?
A: By covering specific formulations, manufacturing processes, and therapeutic uses, the patent creates legal barriers. Competitors must develop substantially different formulations or wait for patent expiration.
Q3: What are the main challenges in defending the patent validity?
A: Demonstrating patentability requires showing novelty, inventive step, and non-obviousness over prior art, especially given the widespread use of lipid-based delivery systems.
Q4: Is there any scope for extending protection beyond this patent?
A: Yes, applicants can file divisional applications, continuation patents, or pursue supplementary protection certificates to extend market exclusivity.
Q5: How does the patent landscape impact licensing opportunities?
A: The broad claims and international patent family make EP2487162 a valuable asset for licensing, especially in markets where lipid formulations of similar drugs are valuable.
