Scope of Patent EP2859886
The scope of a patent defines the breadth of legal protection conferred through its claims. EP2859886 primarily centers on the chemical composition, therapeutic application, and use of certain substituted piperidine derivatives as inhibitors of specific biological targets, presumably impacting neurological or metabolic diseases.
Core Elements of Scope:
- Chemical Composition: The patent claims a class of 2-aryl- or 2-alkyl-substituted 4-substituted piperidines with specific substituents, stereochemistry, and structural features. These derivatives are described with a sufficient degree of structural variety to cover numerous analogs within this chemical space.
- Therapeutic Use: The invention claims the application of these compounds as inhibitors of NYX-0195, NYX-0196, and NYX-0197, which are likely code names for specific biological targets or pathways. The claims encompass both the compounds themselves and their use in medical treatment.
- Synthetic Methods: The patent may include claims on methods of synthesis, broadening protection to chemical processes involved in producing these compounds.
- Pharmacological Activities: The patent encompasses the pharmacological activity profiles, particularly the inhibition or modulation of the NYX-019x targets, which could imply claims covering methods of administering the compounds for therapeutic effects.
Limitations & Exclusions:
- The scope explicitly excludes compounds with known prior art structures that do not fall within the defining features.
- Specific embodiments or narrower claims are tailored to particular substituents and stereochemistry, providing fallback positions for patent enforcement or defense.
