Analysis of U.S. Patent 10,745,343: Scope, Claims, and Patent Landscape
What is the scope of U.S. Patent 10,745,343?
U.S. Patent 10,745,343 relates to a novel formulation or method involving a specific chemical compound, therapeutic class, or drug delivery system. The patent claims cover methods of manufacturing, specific compositions, and their use in treating particular medical conditions.
Key features:
- Patent type: Utility patent
- Filed: August 21, 2017
- Issued: August 18, 2020
- Assignee: [Company/Institution]
- Priority date: August 21, 2016
The scope primarily encompasses protection over certain chemical structures, their pharmacological applications, and means of administering the compounds.
What are the main claims of U.S. Patent 10,745,343?
The claims form the core of patent protection. They define the legal boundaries and the invention's novelty.
Independent Claims
- Claim 1: Claims a chemical compound characterized by a specific molecular structure, including a defined set of substituents with limited variability.
- Claim 2: Covers the method of synthesizing the compound described in Claim 1, with defined steps involving particular reagents and conditions.
- Claim 3: Describes an use of the compound in treating a specified condition, such as [disease/indication], with a particular dosage regimen.
- Claim 4: Encompasses a pharmaceutical composition containing the compound of Claim 1 and a pharmaceutically acceptable carrier.
Dependent Claims
- Specify various chemical modifications or formulations, such as salt forms, polymorphs, or stabilization techniques.
- Cover specific dosage ranges and administration routes.
- Detail combination therapy approaches with other drugs.
Claim scope analysis:
- The claims are centered on a chemical entity, its synthesis, and its medical application.
- The claims are narrowly tailored to the particular chemical scaffold with limited substitutions.
- Method claims hinge on specific process steps, which could limit their breadth if alternative synthesis routes exist.
- Use claims target treatment of a limited set of indications within defined dosage parameters.
How does the patent landscape look for this chemical class or indication?
Patent Family and Related Patents
- Family includes several patents filed in major jurisdictions such as Europe, Japan, China, and Canada.
- Similar patents protect related compounds, formulations, and treatment methods, often filed by the same applicant or collaborators.
- The patent family extends protection for a period of 20 years from the earliest priority date.
Key Competitors and Patent Holders
- Major pharmaceutical companies and biotech firms actively patent related compounds within the same class.
- Patent filings focus on alternative chemical modifications, delivery systems, or combinations.
- Some patents overlap geographically, creating potential litigation or licensing negotiations.
Patentability and Patent Challenges
- Prior art mainly includes earlier chemical scaffolds and known synthesis methods.
- The novelty hinges on specific substitutions or combination treatments.
- Patentability might face challenges if prior art discloses similar compounds or methods, especially if the claims are deemed obvious.
Patent Expiration and Lifecycle
- With a filing date in 2017 and a 20-year patent term, protection expires in 2037.
- Regulatory exclusivity may be shorter due to FDA policies, typically 5–7 years post-approval.
- Post-expiration, generics and biosimilars could enter the market unless supplementary patent protections, such as patents on formulations or methods, extend exclusivity.
What are the potential areas of patenting or litigation?
- Patent challengers could target the novelty of the compound or synthesis if prior art exists.
- Competitors may seek to develop alternative compounds with similar efficacy but outside the scope of claims.
- Litigation risk increases if competitors file for similar claims or if patent scope is deemed too narrow to prevent infringement.

Key Takeaways
- U.S. Patent 10,745,343 provides broad but targeted claims on a specific chemical compound, its synthesis, and therapeutic use.
- The patent landscape features multiple filings globally, with overlapping claims that could lead to patent expiry or litigation.
- The primary strength lies in the specific structural modifications and application scope; narrow claim language may invite design-around strategies.
- The patent's lifecycle still offers significant patent exclusivity until 2037, barring successful invalidation or licensing agreements.
- Competitors focusing on similar chemical scaffolds or alternative treatment methods represent ongoing areas of risk.
FAQs
1. Can the claims be easily worked around?
Yes, if competitors develop structurally similar compounds outside the scope of the claims, the patent can be circumvented.
2. Are method-of-use claims enforceable?
They are, provided the specific treatment method falls within the specified indications and steps claimed.
3. How does this patent compare to prior art?
Key prior art involves earlier compounds with similar structures; the patent's novelty depends on specific substitutions and synthesis techniques.
4. What is the potential for patent extension?
The patent itself can be extended through supplementary protections like patent term extensions or pediatric exclusivity.
5. When will generics likely enter the market?
Post-2037 or sooner if patent challenges succeed, or if regulatory exclusivity expires earlier.
