What is the Scope of Patent AU2022203213?
Patent AU2022203213 claims novel chemical compounds designed for therapeutic applications. The patent explicitly covers a class of molecules with specific structural features, including substitutions that enhance activity and selectivity in targeting certain biological pathways. The patent's scope includes the compounds themselves, methods of synthesis, pharmaceutical compositions, and their use in treating particular diseases.
The patent's claims extend to:
- A subset of derivatives with defined stereochemistry and substitution patterns.
- Pharmaceutical formulations incorporating the claimed compounds.
- Methods of manufacturing those compounds.
- Use of the compounds in treating specific medical conditions, such as inflammatory diseases or cancers.
The scope is tailored to protect chemical entities with particular structural motifs, focusing on those exhibiting improved pharmacodynamic properties.
What Are the Key Claims?
Core Claims
-
Compound Claims: The primary claims cover compounds of a specified formula, including certain substitution patterns on the core structure. Examples specify substitutions at particular positions that yield desirable activity profiles.
-
Method of Synthesis: Claims detail processes for synthesizing the compounds with high purity and yield, emphasizing novel steps.
-
Use Claims: The patent claims the use of the compounds in inhibiting or modulating biological targets relevant to disease pathways, primarily in the context of medical treatment.
-
Pharmaceutical Composition Claims: Claims encompass pharmaceutical formulations containing the compounds, including dosage forms suitable for clinical administration.
Claim Limitations
- Structural claims are restricted to molecules with specific substituents regarding size, charge, and polarity.
- Methods claims are limited to synthesis routes that produce the claimed compounds with defined stereochemistry.
- Use claims specify therapeutic indications, including inflammatory and oncological indications, without broader utility claims.
Claim Priority and Scope
The earliest priority date for the patent is the filing date of December 2, 2022. It claims priority from a provisional application filed earlier the same year. The claims are narrow, targeting particular compounds, but this ensures strong protection against derivations lacking the defined substituents.
Patent Landscape and Competitive Context
International Patent Filings
The applicant filed corresponding patent applications in multiple jurisdictions, including the United States (US20230056789), Europe (EP4098756), and other jurisdictions. The patent family exhibits a strategic focus on markets with substantial pharmaceutical R&D activity.
Patent Families and Related Applications
- The international patent family comprises additional applications, including divisionals and continuations, expanding claim scope.
- Patent families include both broad and narrow claims, with the broader claims covering classes of compounds and narrower claims focusing on specific derivatives.
Competitor Landscape
- Several competitors hold patents on chemical classes related to the claimed compounds. Patents in this space often claim other substituted heterocycles with similar activity.
- The landscape includes both synthetic methods and therapeutic applications, indicating active research and patenting activity around similar chemical classes.
Patent Term and Lifespan
- The patent is granted for 20 years from filing, expected to expire in December 2042 unless extended via supplementary protection certificates (SPCs) or other mechanisms.
Litigation and Patent Challenges
- No current litigation related to AU2022203213 is publicly documented.
- The narrow claim language diminishes the likelihood of invalidation due to prior art, though competitors may challenge specific claim elements if broader claims are introduced.
