[Chemical structure notation]
with specific groups attached at designated positions, where variations of substituents are included within the scope of the claim.
Method claims
- Methods of administering the compound to achieve desired pharmacological effects.
- Synthesis routes for creating the specific compounds.
- Use of the compounds for treating diseases associated with the biological target.
Use claims
- Application of the compounds in preventing or treating particular diseases.
- Specific dosage forms and dosing regimens specified, although these are secondary to the structural claims.
Claim limitations
- The claims specify the chemical substitutions, stereochemistry, and configurations that fall within the scope.
- Some claims are dependent, narrowing the scope to particular substituents or formulations.
What is the patent landscape?
Patent family members
- Multiple applications and patents extending coverage internationally, with filings in Europe (EP), Japan (JP), and China (CN).
- Foreign counterparts often build upon or refine the chemical scope, emphasizing protection of key derivatives.
Related patents and prior art
- Prior art includes compounds with similar mechanisms targeting the same biological pathway.
- The patent distinguishes itself through specific structural features that confer selectivity and potency.
Competitive landscape
- Other patents in the same therapeutic class target related proteins but differ in chemical scaffolds.
- Patent filings from competitors focusing on alternative chemistries, suggesting a broad then narrow patent strategy among innovators.
Patent expiration
- Expected patent term expiration around 2036, assuming a 20-year term from filing date (filing date: May 8, 2014).
Patentability considerations
- The novelty rests on the specific chemical features not disclosed in prior art.
- Non-obviousness linked to the particular combination of substituents and their pharmacological profile.
Implications for R&D and commercialization
- The patent provides enforceable rights covering a defined chemical space, limiting competitors from commercializing similar compounds.
- The scope encompasses both the chemical entities and their therapeutic applications, extending to formulations.
- Patent landscape indicates saturation in the broad chemical class, with innovations focusing on specific derivatives.
