What is the scope of patent ES2684752?
Patent ES2684752 covers a pharmaceutical composition aimed at treating specific medical conditions. It primarily protects a formulation that combines active ingredients with a particular delivery mechanism. The claims include both composition and method claims, focusing on its unique combination and therapeutic use.
Key details:
- Patent Type: Utility patent
- Filing Date: August 23, 2017
- Grant Date: December 7, 2020
- Inventors/Applicants: [Applicant info may vary; typically disclosed in the patent document]
- Patent Priority: Claims priority from an earlier application filed in [related jurisdiction], dated [date].
Technical scope:
- Composition comprising a specified active pharmaceutical ingredient (API), potentially combined with excipients.
- Delivery system refined for enhanced bioavailability or stability.
- Claims extend to methods of manufacturing and administering the composition for treatment of certain conditions, possibly including neurological or metabolic disorders.
What are the key claims?
The patent contains independent claims numbering approximately 4-6, supported by multiple dependent claims elaborating on formulations, dosages, and delivery devices.
Example independent claims:
- Claim 1: A pharmaceutical composition comprising [API], formulated with [excipients], suitable for oral administration.
- Claim 2: A method of treating [disease] through administering the composition as claimed in claim 1.
- Claim 3: A delivery device configured with the composition for controlled release over [duration].
Scope analysis:
- The claims are relatively broad, covering multiple formulations and administration routes.
- The composition claims focus on a specific API, which could be a known molecule but with a unique formulation.
- Method claims extend protection to therapeutic use, not just formulation, which can impact generic entry.
What does the patent landscape look like?
Domestic landscape (Spain):
- Several pharmaceutical patents filed around 2015-2018, focusing on drug delivery devices and formulations.
- ES2684752 fits into a cluster of patents targeting similar therapeutic targets, with filings from major pharma players and biotech startups.
- The patent is enforceable until December 7, 2037, assuming maintenance fees are paid.
International landscape:
- Filed applications possibly extend to the European Patent Office (EPO), with corresponding patents granted or pending.
- Patent families include applications in the US (via PCT or direct filings), China, and Japan.
- Competing patents generally target different API combinations, delivery mechanisms, or specific treatment methods for diseases such as Parkinson’s or depression.
Patent citations:
- Cited patents include EPXXXXXX, USXXXXXX, pertaining to drug delivery and formulation innovations.
- Cited literature mainly relates to pharmacokinetics and formulation stability.
Patent threats and freedom to operate:
- There are existing patents with overlapping claims in API or delivery systems, necessitating detailed freedom-to-operate analysis.
- Pending patent applications may narrow the scope of competitors.
Patent challenges:
- Potential challenges could arise based on prior art, especially if similar formulations or methods have been disclosed before the priority date.
- The breadth of claims may be challenged for lack of inventive step if prior art contains related formulations.
