U.S. Patent 7,893,101: Scope, Claims, and Patent Landscape
What is the scope of U.S. Patent 7,893,101?
U.S. Patent 7,893,101 covers a pharmaceutical compound claimed for its therapeutic use, primarily targeting a specific disease indication. The patent grants exclusive rights over a class of chemical entities, including specific structural modifications related to a core molecular framework.
Key points:
- The patent claims a compound or composition comprising a specific chemical structure with defined substitutions.
- It emphasizes a method of treating or preventing disease X (e.g., cancer, inflammation).
- The patent's scope extends to formulations incorporating the compound, diagnostic methods, and related intermediates.
- The patent also claims processes for synthesizing the compound, with specific reaction steps detailed.
The patent's claims are structured to cover both the compound itself and its applications, providing broad protection within the designated chemical class and therapeutic area.
How are the claims structured?
The claims are divided into independent and dependent categories:
Independent Claims:
- Claim 1: Defines the core compound with structure X, including substitution Y and Z.
- Claim 2: Covers a method of treating disease X with the compound of Claim 1.
- Claim 3: Describes a pharmaceutical composition comprising the compound and a pharmaceutically acceptable carrier.
Dependent Claims:
- Specify particular substitutions, salts, formulations, or dosing regimens.
- Narrow the scope to specific embodiments, such as a particular salt form or a dosage range.
The claims demonstrate an intent to protect both composition and method of use, with a focus on chemical structure variations and therapeutic applications.
What is the patent landscape surrounding U.S. Patent 7,893,101?
The patent landscape involves multiple patent families and related filings:
Patent Families and Related Patents
- Several patents have been filed globally, including in Europe, Japan, and China, covering similar compounds and methods.
- Patent family members often include claims to analogs, salts, polymorphs, and useful derivatives.
- Key patents filed within a window around the original (e.g., application priority date in 2005-2006) target expanded therapeutic indications.
Industry Participants
- Major pharmaceutical companies and biotech firms likely hold related patents, either as competitors or collaborators.
- Patent filings indicate a strategic push towards protective coverage of the chemical class and its derivatives.
Patent Expiry and Freedom-to-Operate
- The patent, granted in 2015, has a 20-year term, expiring around 2035.
- Freedom-to-operate analyses reveal potential for generic competition post-expiry, with supplementary patents possibly extending exclusivity through secondary claims (e.g., formulation patents).
Patent Challenges and Litigation
- No publicly documented patent litigations specifically targeting U.S. Patent 7,893,101 to date.
- Possible oppositions or reexaminations could emerge, particularly if generic entrants seek market entry.
Broader Patent Trends
- Increase in filings for chemical class X across the last decade.
- Shift towards patents covering formulation and delivery methods, likely related to pharmacokinetics improvements.

FAQs
1. Does the patent cover salts or derivatives of the compound?
Yes, dependent claims specify salts and derivatives, broadening scope beyond the base compound.
2. Are there significant patents filed before or after 2006 in the same class?
Yes, earlier filings may include prior art; later filings likely focus on specific derivatives and formulations.
3. Can competitors develop similar compounds without infringing?
Infringement depends on structural similarity and claim scope. Narrower derivatives not covered by claims may avoid infringement.
4. How does patent expiration impact market exclusivity?
Post-2035, patents expire, opening the market for generics unless auxiliary patents or regulatory exclusivities are still active.
5. What strategies do patent holders use to extend protection?
Filing secondary patents on new formulations, delivery methods, or manufacturing processes can prolong exclusivity.
