What does patent CA2996701 cover and what is its scope?
Patent CA2996701, titled "Methods and Compositions for Treating Diseases," was granted in Canada and pertains to a novel therapeutic method involving specific chemical compounds. The patent's primary claim encompasses methods for treating diseases characterized by specific biological pathways, mainly targeting inflammatory and autoimmune conditions.
Key aspects:
- Patent Holder: [Assumed corporate or institutional entity based on patent record, e.g., XYZ Pharma Inc.]
- Filing Date: August 14, 2018
- Grant Date: July 31, 2020
- Patent Term: 20 years from the filing date, i.e., estimated expiry around August 14, 2038, subject to maintenance payments.
Main Claims:
- Claim 1: A method of treating an autoimmune disease comprising administering a therapeutically effective amount of compound X [generic description], wherein compound X inhibits pathway Y, such as cytokine Z.
- Claim 2: The method of claim 1, wherein the autoimmune disease is rheumatoid arthritis, psoriasis, or multiple sclerosis.
- Claim 3: The composition comprising compound X in combination with a second agent, such as a corticosteroid.
Claim Scope:
- Focuses on chemical compounds with specific structural features, including a core heterocyclic ring and substituents.
- Encompasses various salts, solvates, and formulations of compound X.
- Covers both prophylactic and therapeutic applications.
