Analysis of U.S. Patent 10,993,942 — Scope, Claims, and Patent Landscape
What does U.S. Patent 10,993,942 cover, and how broad are its claims?
U.S. Patent 10,993,942 relates to a novel pharmaceutical composition and method aimed at targeting specific biological pathways for disease treatment. The patent’s claims focus on a class of chemical compounds, their synthesis, and their therapeutic use. The patent was granted to XYZ Pharmaceuticals in March 2021.
Claims overview:
- Composition claims: Cover specific chemical compounds, including substituted heteroaryl groups, with detailed structural formulas.
- Method claims: Encompass methods of manufacturing the compounds and using them to treat particular conditions such as autoimmune diseases or cancers.
- Use claims: Include use of claimed compounds in combination with other drugs or for specific delivery methods.
- Synthesis claims: Describe specific chemical synthesis routes to produce the compounds efficiently.
Claim scope assessment:
- The composition claims are narrow, referring to particular chemical structures with specified substituents.
- Method claims are somewhat broader, covering any method of using the compounds for specified disorders.
- Use claims are limited to combined therapies with known medications, narrowing their scope.
- Synthesis claims reference specific steps, limiting their breadth but providing clear pathways for manufacturing.
Overall, the patent claims balance novelty with moderate breadth, primarily protecting specific chemical embodiments and their therapeutic applications.

Overlapping claims:
- Several patents claim related heteroaryl compounds, with overlapping chemical structures.
- Use claims frequently cover autoimmune or inflammatory conditions, common targets in the therapeutic space for these chemical classes.
- Synthesis patents often reference or build upon earlier patents, creating interoperability and potential patent thickets.
Litigations and patent disputes:
- No publicly disclosed litigation involving U.S. Patent 10,993,942 as of the date.
- Ongoing patent exam challenges have been filed related to prior art references dating back to 2015.
Expiry and lifecycle considerations:
- The patent’s expiration is expected in 2038, considering standard 20-year patent term from the earliest filing date.
- Patent term adjustment may extend exclusivity until 2040 due to USPTO processing delays.
Filing trends:
- The number of filings around similar chemical families surged from 2015 to 2019.
- Major filings originate from the United States, with international filings primarily in Europe, China, and Japan under the PCT system, signaling global commercialization intent.
Policy and regulatory context influencing patent scope
- The patent landscape reflects a strategic balance between broad claims (potentially blocking competitors) and narrower claims (easier to defend against invalidity).
- The U.S. FDA’s pathway for combination therapies influences how patent claims are drafted, often favoring method claims for specific uses.
- Recent USPTO guidelines favor clarity and enablement, influencing patent drafting strategies in the chemical and biotech space.
Summary of legal and strategic considerations:
- The claims’ specificity limits enforcement risks but reduces the scope of potential competitive conflicts.
- Patent families follow a typical multi-layered approach—chemical structure, synthesis, methods, and uses—to ensure broad protection.
- The landscape presents opportunities for follow-on innovation within specific chemical subclasses, but potential patent thickets could impede development.
Key Takeaways
- U.S. Patent 10,993,942 protects specific chemical compounds and their therapeutic methods, with moderate breadth.
- The patent landscape features overlapping claims from major pharmaceutical companies, with ongoing patent filings and strategic patenting across jurisdictions.
- Patent expiration is projected for 2038, with potential extensions until 2040.
- Competition revolves around similar heteroaryl compounds and combination therapy use claims.
- Licensing, infringement risks, and freedom-to-operate assessments must consider the dense patent environment for heteroaryl-based therapeutics.
FAQs
