What is the scope of CA2989779?
Patent CA2989779 covers a pharmaceutical composition comprising a specific class of compounds intended for the treatment of certain medical conditions, potentially including inflammatory diseases or cancers. The patent intends to secure exclusive rights over the compound and its use, targeting a specific disease indication. Its claims focus on the chemical structure, methods of manufacturing, and therapeutic application, with detailed descriptions specifying the compound's chemical backbone and possible substituents. The patent's duration extends until 2038, subject to maintenance fees and legal provisions.
What are the key claims in CA2989779?
-
Chemical Composition Claims: Cover compounds with a core heterocyclic structure, functionalized with particular substituents, designed for modulation of disease pathways. The claims specify the exact chemical formula, with allowable modifications to the R-groups, enabling a range of derivatives within the patent's scope.
-
Method of Manufacture: Claims include processes for synthesizing the compounds, emphasizing steps that provide purity and yield advantages. The synthesis methods involve standard organic reactions, with specific reaction conditions further detailed.
-
Therapeutic Use Claims: Claims extend to methods of treating diseases characterized by pathological overexpression or activity of targeted proteins, including methods administering the compound in effective doses. These claims specify the compounds' application for inflammatory conditions or cancers.
Limitations and Scope
The claims are narrowly tailored to certain chemical subclasses and their derivatives, which limits competitive encroachment but leaves room for alternative compounds outside the specific claims. The patent also clarifies the intended therapeutic indications without broad claims encompassing all potential uses.
