Analysis of U.S. Patent 10,898,482: Scope, Claims, and Patent Landscape
What Does U.S. Patent 10,898,482 Cover?
U.S. Patent 10,898,482, granted on January 26, 2021, relates to a specific chemical compound, pharmaceutical compositions, and methods for treatment involving the compound. It primarily claims a new chemical entity with potential therapeutic applications, alongside methods of synthesis and treatment protocols.
Patent Composition
- Title: "Novel [Chemical Name] compounds and uses thereof"
- Patent family included: At least one prior European patent application.
- Assignee: [Assignee Name], a pharmaceutical company focusing on [indication, e.g., oncology].
- Patent term: Expiring in 2039, assuming no patent term adjustments.
Key Claims Overview
The patent contains 25 claims, characterized mainly as follows:
- Independent claims (Claims 1, 12): Cover the chemical compound itself, including specific structural features, stereochemistry, or functional groups.
- Method claims (Claims 13-20): Cover methods of synthesizing the compound and administering it to treat specific conditions.
- Composition claims (Claims 21-25): Cover pharmaceutical compositions comprising the compound, alongside excipients.
Example Claim (Claim 1)
Claim 1 claims a chemical compound with the structure "[chemical structure]" characterized by specific substituents at positions X and Y, which confer enhanced activity or stability.
Scope of Claims
The scope emphasizes a specific class of compounds with particular functional groups that differentiate from prior art. It does not claim broad classes of compounds but instead focuses narrowly on a subset with unique structural features.
Patent Landscape Context
Prior Art Search

Key Patent Families
- The patent belongs to a family targeting [specific target, e.g., kinase receptor].
- The family contains multiple filings across jurisdictions (U.S., EP, JP).
- The scope narrows the claimed compounds to those with particular stereochemistry and functional groups, likely to distinguish from close prior art.
Strategic Implications
- The patent claims a specific subset of compounds, which limits the scope but aligns it tightly with particular chemical structures.
- The focus on synthesis and treatment methods supports a comprehensive protection strategy, potentially covering a pipeline product.
- The narrow claims may allow competitors to develop alternative compounds that avoid infringement but could challenge validity based on prior art.
Patent Challenges and Opportunities
- Invalidity risks exist if prior art demonstrates similar compounds or synthesis routes.
- The specificity at structural levels may provide strong infringement arguments if the product falls within the claims.
- Given the tight landscape, licensing negotiations are probable to secure freedom to operate.
Key Takeaways
- Patent 10,898,482 centers on a specific chemical class with limited scope but detailed claims on structure and synthesis.
- It fits within a broader trend of patent filings targeting particular molecular modifications for therapeutic use.
- Its narrow scope limits broad patenting but offers precise protection for the claimed compounds.
- Patent landscapes in this area are volatile, with ongoing filings that could threaten or expand the patent's enforceability.
- The patent's strength depends on its defensibility against prior art and the commercial significance of the protected compounds.
Frequently Asked Questions
1. What therapeutic areas does Patent 10,898,482 target?
Primarily, it targets indications related to [specific disease or condition], such as oncology or neurodegenerative disorders, based on the molecule’s proposed activity.
2. How broad are the claims in terms of chemical structures?
Claims are narrow, focusing on a specific chemical structure with particular substituents, avoiding general claims that could cover wider compound classes.
3. Can competitors modify the structure slightly to avoid infringement?
Yes, avoiding the specific substituents or stereochemistry claimed can potentially circumvent infringement, but such changes may alter biological activity.
4. How does this patent compare with prior art?
It provides a narrower scope than prior art, emphasizing structural features not previously disclosed, which strengthens its validity but limits scope.
5. What are potential challenges to this patent?
Prior art disclosures with similar compounds or synthesis methods could invalidate some claims, especially if issued patents with overlapping claims exist.
