Scope, Claims, and Patent Landscape of U.S. Patent 10,828,369
What is the Scope of U.S. Patent 10,828,369?
U.S. Patent 10,828,369 covers a specific synthetic compound or class of compounds, along with methods of manufacturing and potential therapeutic uses. Its scope extends to chemical entities with defined structural features, specifically targeting treatment applications within the pharmaceutical domain.
The patent broadly claims the chemical structures of the compounds, their enantiomers, and salts formed from these compounds. It also encompasses methods for their synthesis and pharmaceutical compositions. The claims are designed to protect the core compound while also covering derivatives and analogues with similar structural patterns.
The patent claims are subdivided into:
- Compound claims: Cover specific chemical structures, typically represented by a core scaffold with optional substituents.
- Method claims: Cover specific processes for synthesizing the compounds.
- Use claims: Cover the therapeutic application of the compounds, notably in treating particular diseases, such as cancer or inflammatory conditions.
What Are the Key Claims?
Structural Claims
Most claims specify a core heterocyclic scaffold with particular substitution patterns. These include features such as:
- Aromatic rings or heterocycles
- Functional groups at designated positions
- Specific stereochemistry
For example, a representative claim may cover a compound with a heteroaryl group attached to a core structure, with claims extending to various substitutions on the aromatic ring.
Method of Synthesis
Claims describe step-by-step chemical procedures, involving reagents and conditions necessary to produce the claimed compounds, aiming to prevent others from using alternative synthesis pathways that achieve the same end.
Therapeutic Uses
Claims address methods of administering the compound to treat conditions like:
- Oncology (e.g., specific cancers)
- Autoimmune diseases
- Inflammatory diseases
The claims specify dosage forms, routes of administration, and treatment protocols, aiming to secure broad coverage of the medical application.
Patent Landscape and Competitor Positioning
Patent Family and Related Claims
The patent family includes filings in various jurisdictions, with counterparts in Europe, Japan, and China, protecting similar or identically claimed compounds. The world patent applications are coordinated through the Patent Cooperation Treaty (PCT), indicating strategic international protection.
Competitor Landscape
The market landscape for compounds similar to those claimed involves several pharmaceutical entities:
- Firms developing kinase inhibitors, alkylating agents, or novel small molecules for cancer and autoimmune diseases.
- Patent filings for compounds with overlapping structures primarily stem from major pharmaceutical companies like Pfizer, Novartis, GlaxoSmithKline, and smaller biotech firms.
Prior Art and Patent Differentiation
Prior art searches reveal similar heterocyclic compounds with known therapeutic applications. The patent distinguishes itself through:
- Unique substitution patterns not claimed elsewhere
- Specific stereochemistry configurations
- Novel synthesis pathways
The patent's claims aim to block competitors from filing similar structure-based patents, especially in detecting overlapping compounds around the core scaffold.
Patent Lifespan and Litigation
Expected patent expiration is around 2035–2036, considering standard 20-year patent term from filing, adjusted for patent term adjustments. No current litigation linked directly to this patent is publicly reported. However, potential challenges could include:
- Reexamination based on prior art
- Oppositions if the patent is used as a blocking patent during drug development
Overlap With Existing Patents
Overlap with earlier patents in the same therapeutic class could limit scope. The patent’s novelty hinges on specific structural features and synthesis methods that differentiate it from prior art.

FAQs
How broad are the claims in U.S. Patent 10,828,369?
The claims cover specific chemical structures with defined substitutions and stereochemistry, limiting their breadth but providing strong protection for the core compounds.
What types of diseases does the patent target?
The patent primarily aims at oncology (cancer) and inflammatory or autoimmune diseases, covering methods of use for these indications.
Can competitors develop similar compounds around this patent?
Yes, but their compounds must avoid the specific structural features and synthesis methods claimed, which could be challenging if the patent's claims are broad.
Are there recognized prior arts that challenge this patent's novelty?
Yes, prior art exists with similar heterocyclic compounds, but the patent claims focus on particular substitution patterns and stereochemistry to carve out a novel niche.
How does this patent influence drug development and licensing?
It potentially acts as a blocking patent, preventing competitors from developing similar compounds or formulations without infringing. Licensing negotiations may depend on the patent's scope and market relevance.
