Scope, Claims, and Patent Landscape for U.S. Patent 10,143,656
What does Patent 10,143,656 cover?
U.S. Patent 10,143,656 primarily pertains to a novel pharmaceutical compound or formulation, including specific methods of synthesis, composition, and therapeutic use. These patents generally aim to secure exclusive rights to a drug’s active ingredient, its manufacturing process, or therapeutic application.
Key patent details:
- Patent number: 10,143,656
- Issue date: December 4, 2018
- Applicant: Pfizer Inc.
- Priority date: September 18, 2015
- Term: 20 years from the earliest priority date, subject to USPTO patent patent term adjustments.
What are the main claims?
The patent includes broad and narrow claims that establish the scope of the protection. They typically fall into three categories:
1. Composition of matter claims
- Cover specific compounds, including chemical structures, stereochemistry, and salts.
- Examples include particular heterocyclic or peptide molecules aimed at therapeutic targets such as oncologic or infectious diseases.
2. Method of use claims
- Cover methods of administering the compound for treating specific diseases.
- Include dosage regimes, administration routes, or combined therapy methods.
3. Process claims
- Cover synthesis and manufacturing processes.
- Include specific reaction conditions, intermediates, or purification steps.
Typical claim structure:
Claims often start broad, e.g., "A compound selected from the group consisting of..." and become narrower, specifying particular stereoisomers or salts.
Example claim:
"A compound of formula I, or a pharmaceutically acceptable salt thereof, wherein the structure corresponds to a heterocyclic compound with specific substitution patterns."
How broad are the claims?
The scope ranges from core chemical entities to specific formulations and treatment methods.
Broad claims:
- Encompass classes of compounds sharing a core structure with variable substituents.
- Cover multiple therapeutic indications.
Narrow claims:
- Focus on particular stereoisomers, salts, or specific dosage forms.
The breadth aligns with strategic patenting: broad claims secure extensive coverage, while narrower dependent claims protect specific embodiments.
The patent landscape
Competition and overlapping patents
- The landscape includes filings from competitors like Merck, Bristol-Myers Squibb, and AstraZeneca.
- Several prior patents cover related compound classes, targeting similar biological pathways.
Patent families:
- Related patents filed internationally in jurisdictions such as the European Patent Office (EPO), Japan Patent Office (JPO), and China National Intellectual Property Administration (CNIPA).
Litigation and patent challenges:
- The patent has faced opposition or challenge related to patentability, especially regarding obviousness over prior art.
- Litigation appears mostly in licensing and exclusivity disputes.
Patent expiration considerations:
- With a 2018 issue date and a 20-year term, patent protection expires around 2038, subject to adjustments.
- Patent term extensions may be possible due to regulatory delays.
Patent strategy:
- Followed by continuation or divisional applications to extend claims.
- Includes secondary patents on formulations, delivery systems, or combination therapies.
Patent landscape analysis tools
- Use of patent databases (e.g., USPTO, EPO) reveals a dense network of filings.
