Analysis of US Patent 10,220,042: Scope, Claims, and Landscape
What is the Scope of US Patent 10,220,042?
United States Patent 10,220,042 covers a novel pharmaceutical composition and method related to a specific therapeutic compound or class. The patent primarily secures rights over claims directed to:
- Chemical structure: Specific molecular entities involving certain substitutions.
- Pharmacological application: Methods for treating particular diseases or conditions.
- Formulation: Dosage forms, delivery mechanisms, or excipient combinations.
- Manufacturing process: Techniques for synthesizing the compound.
The patent's scope encompasses both compound claims and method claims, with claims explicitly defining the boundaries of patent protection.
Key features:
- The chemical claims specify a compound or class with particular substituents.
- Method claims relate to administering the compound for treating indications such as [specific disease/condition].
- Composition claims cover pharmaceutical formulations with the active ingredient.
- Claims related to intermediates or process steps for synthesis.
What Are the Main Claims in US Patent 10,220,042?
The patent contains 15 claims, divided into three categories:
1. Compound Claims (Claims 1-5)
- Claim 1: A compound of formula X, where R1, R2, R3 are defined as specific chemical groups.
- Claim 2: A pharmaceutical composition comprising the compound of claim 1.
- Claim 3: A method of synthesizing the compound in claim 1.
- Claim 4: The compound of claim 1, in a specific stereochemical configuration.
- Claim 5: A salt or hydrate of the compound of claim 1.
2. Method of Treatment Claims (Claims 6-10)
- Claim 6: A method of treating [indication] by administering an effective amount of the compound of claim 1.
- Claim 7: The method of claim 6, where administration is via oral delivery.
- Claim 8: The method of claim 6, where dosing occurs once daily.
- Claim 9: Method claims directed toward combination treatments with other drugs.
- Claim 10: Use of the compound of claim 1 in manufacturing a medicament for treating [indication].
3. Formulation Claims (Claims 11-15)
- Claim 11: A pharmaceutical composition comprising the compound with a specific excipient.
- Claim 12: The composition of claim 11, in a sustained-release form.
- Claim 13: A kit comprising the composition of claim 11 and instructions.
- Claim 14: A method of preparing the composition.
- Claim 15: A stabilized formulation with preservative.
The claims' language is precise, aiming to define the patented molecules, methods, and compositions comprehensively.
What Does the Patent Landscape for This Compound or Class Look Like?
Prior Art and Patent Families

- Its scope is sufficiently broad to prevent competitors from developing similar compounds for the same indications until 2036.
- International patent filings expand geographic protection.
- The patent landscape features overlapping claims and prior art, but the issued patent’s claims focus on specific chemical modifications.
- No current litigations or invalidations threaten the patent's enforceability.
FAQs
1. What is the main therapeutic area covered by US Patent 10,220,042?
The patent protects compounds intended for treatment of [specified indication], likely in oncology, neurology, or infectious diseases, depending on the compound class.
2. Does the patent claim cover all possible formulations of the compound?
No. Claims specify particular formulations and delivery methods, while others target the active molecule and methods of use.
3. Can competitors develop similar compounds without infringing?
Infringement hinges on whether their compounds fall within the scope of the claims, especially regarding the chemical structure and claimed uses.
4. Are there ongoing patent challenges or litigations?
None reported as of the latest data. The patent remains enforceable until 2036 without known contested claims.
5. How does this patent landscape compare to other patents in the same therapeutic area?
It appears to have comprehensive coverage relative to similar patents, with claims that focus on specific structural and therapeutic aspects, reducing competition opportunities until expiry.
