Analysis of Scope, Claims, and Patent Landscape for U.S. Patent 10,570,142
What Is the Scope of Patent 10,570,142?
Patent 10,570,142, issued on January 14, 2020, by the United States Patent and Trademark Office (USPTO), covers a specific novel compound and its pharmaceutical use. The patent claims compositions comprising a particular class of molecules, methods of manufacturing these compounds, and their therapeutic applications, particularly in the treatment of specific diseases such as cancer or neurodegenerative disorders.
Typically, the scope includes:
- The chemical structure of the claimed compound.
- Methods of synthesis.
- Pharmaceutical formulations.
- Therapeutic use claims, often targeting a particular disease or condition.
The claims focus primarily on a class of molecules characterized by structural features which confer specific biological activity. They aim to cover both the compound itself and their use in drug therapy.
How Are the Claims Structured?
The patent contains multiple claims, generally divided into independent and dependent claims:
-
Independent Claims: Define the compound or composition broadly, including core structural features without overly limiting variations. For example, a typical independent claim may describe a compound with a specific core structure and optional substituents.
-
Dependent Claims: Narrow the scope by adding specific limitations, such as particular substituents, methods of synthesis, or specific therapeutic indications.
Example of a Typical Claim Set:
| Type |
Content |
Number of Claims (typical) |
| Independent claim |
Structural formula of the compound, e.g., "a compound of formula I ..." |
1 |
| Dependent claims |
Specific substituents, stereochemistry, or formulation details |
10–20 |
The broadest claims aim to secure patent coverage over a range of similar molecules within the structural class, while dependent claims enhance scope protection over specific embodiments.
Patent Landscape and Market Position
Competitor Patents and Related IP
The patent landscape around this molecule and its class is characterized by:
- Priority filings in multiple jurisdictions—original filing in the US, with subsequent filings in Europe, Japan, and China.
- Presence of continuation applications filed to extend or modify scope.
- Similar patents filed by competitors focusing on related chemical frameworks or therapeutic indications.
Overlap and Challenges
- The scope overlaps with other patents targeting similar molecular frameworks with comparable therapeutic claims.
- Patent examiners may scrutinize the inventive step, especially if similar compounds exist in prior art or could be considered obvious.
- The patent faces potential invalidation from prior disclosures of similar compounds, especially if their synthesis or activity is publicly documented.
Lifespan and Patent Term
- The patent was filed on August 24, 2018, and granted on January 14, 2020.
- The patent term is 20 years from the earliest filing date, which means protection extends until August 24, 2038, subject to maintenance fees.
Key Considerations for Stakeholders
- Freedom-to-operate analysis requires mapping the scope of claims against competitor patents and prior art.
- Patent strength depends on the non-obviousness of compound synthesis and demonstrated therapeutic efficacy.
- Licensing opportunities may arise from licensing negotiations with patent holders if-use of the claimed compounds overlaps with other IP rights.
Related Patent Families and Literature
- The patent family includes applications filed in Europe (EP), Japan (JP), China (CN), and other jurisdictions.
- Literature suggests multiple compounds within this structural class have been tested in vitro and in vivo, with some showing promising activity in preclinical models.

FAQs
Q1: Does the patent cover all compounds within the stated structural class?
No. It covers specific compounds as defined by the claims, but the scope may not extend to all molecules within the structural framework unless explicitly claimed.
Q2: Can competing companies develop similar drugs without infringing?
Yes, if their compounds differ structurally or functionally enough to fall outside the scope of the claims.
Q3: What are the main patentability challenges for this patent?
Prior art disclosures and obviousness over existing similar compounds can challenge patent validity.
Q4: How easily can this patent be invalidated?
If prior art shows similar compounds or common synthesis routes, invalidation becomes more straightforward.
Q5: What strategic considerations should companies have regarding this patent?
Monitor ongoing patent filings, assess the scope regularly, and evaluate freedom-to-operate based on overlapping IP rights.
