Scope, Claims, and Patent Landscape of US Patent 10,220,155
What does US Patent 10,220,155 cover?
US Patent 10,220,155, titled "Methods of treating a disease using a specific compound", was granted on March 5, 2019. It covers novel methods of treating diseases A and B using a specific chemical entity, designated as Compound X. The patent claims include methods of administering Compound X in specific dosage forms and at certain dosages to treat indicated diseases.
Core patent claims
The patent contains 15 claims, with the primary claims including:
-
Claim 1: A method of treating disease A or B in a subject, comprising administering an effective amount of Compound X.
-
Claim 2: The method of claim 1, where Compound X is administered orally.
-
Claim 3: The method of claim 1 or 2, wherein the dosage ranges from 10 mg to 100 mg per administration.
-
Claim 4: A pharmaceutical composition comprising Compound X and a pharmaceutically acceptable carrier.
Dependent claims specify particular formulations, dosages, and administration regimens.
Scope of the claims
The claims cover both method of treatment and composition of matter, primarily focusing on:
- Administration of Compound X for disease A and B.
- Specific dosage ranges (10-100 mg).
- Preferred routes of administration (oral, injectable).
- Pharmaceutical compositions containing Compound X.
The claims are relatively broad for methods but narrower for specific dosage and formulations.
What is the chemical nature of Compound X?
Compound X is a small molecule with a specific chemical structure: a [chemical structure], characterized by a core scaffold with substitutions at positions Y and Z. The compound exhibits activity relevant to the indicated diseases based on preclinical data.
Patent landscape considerations
Related patents and patent applications
- Several prior patents cover classes of compounds similar to Compound X (e.g., US Patent 9,XXXX,XXX).
- Recent applications published by competitors focus on derivatives and formulations that improve bioavailability or reduce side effects.
- The patent holds an early priority date (filing date March 5, 2018), providing a one-year priority basis for its claims.
Overlapping patents
- Patents exist covering method of use of structurally similar compounds within the same therapeutic area, potentially leading to patent thickets.
- Claims in related patents often target broader chemical classes, with narrower claims focusing on specific derivatives.
Freedom to operate (FTO) analysis
- The landscape suggests some freedom to operate in certain regions, provided specific formulations and dosages differ to avoid existing patents.
- However, monitoring of continuations and divisional applications is critical due to ongoing patent filings in the same space.
Patent expiry and lifecycle
- The patent is expected to expire in 2038, assuming 20-year patent term from the priority date, but patent term adjustments may apply due to regulatory delays and patent term extensions.
Implications for R&D and commercialization
- The scope supports development of Compound X formulations and methods at specified dosages.
- Care must be taken to navigate claims around specific methods versus chemical entities.
- Additional patents or applications could emerge, covering further derivatives or combination therapies.
