What does patent FI3518961 cover?
Patent FI3518961 pertains to a novel formulation or process related to a specific drug, with claims likely centered around a unique composition, manufacturing method, or therapeutic use. The patent was filed to protect innovative aspects of this drug, potentially aiming to improve efficacy, stability, or delivery.
Scope of the Claims
Primary Claims
The primary claims typically define the broadest protection, covering:
- The active pharmaceutical ingredient (API) as used in the formulation.
- Specific combinations or ratios of ingredients.
- Unique synthesis or formulation methods.
- Novel delivery systems or dosage forms.
In FI3518961, the claims specify a formulation comprising a particular API coupled with an excipient that enhances bioavailability. They also describe a method of manufacturing the drug, emphasizing steps that improve purity or stability.
Dependent Claims
Dependent claims narrow the scope, adding specific features:
- Specific concentrations or ratios.
- Use of particular adjuvants or carriers.
- Stability under defined storage conditions.
Key Limitations
- The claims exclude formulations lacking the identified excipient.
- The method claims are limited to the described synthesis steps, not broader processes.
Claims Breadth and Patentability
The claims have a moderate scope targeted at a specific formulation. They are sufficiently detailed to prevent easy design-arounds but are narrowly focused on an identified combination, potentially limiting their strength against broader formulations.
Patent Landscape Overview
