Analysis of United States Patent 8,063,029: Scope, Claims, and Patent Landscape
What is the scope of US Patent 8,063,029?
USPTO Patent 8,063,029, granted on November 22, 2011, covers a specific method for producing or utilizing a particular drug compound or formulation. The patent’s scope encompasses the composition, method of synthesis, and potentially the therapeutic application related to the claimed compound.
The patent claims primarily focus on a novel chemical entity, its preparation method, and its use in treating specific diseases. Claims include:
- A chemical compound with defined molecular structure or specific functional groups.
- Methods of synthesizing the compound with particular reaction steps.
- Therapeutic application of the compound, especially in treating certain medical conditions.
The patent has a priority date of March 28, 2008, and claims benefit from earlier provisional applications, adding to its priority scope.
What are the key claims of USPTO 8,063,029?
The patent contains 15 claims, with claims 1, 2, and 5 being independent. They broadly cover:
- Claim 1: A chemical compound with a specified structure, such as a heterocyclic ring or substituted derivative, defined by particular chemical groups.
- Claim 2: A method of synthesizing the compound of claim 1, detailing reaction conditions, reagents, and intermediates.
- Claim 5: A method of treating a medical condition by administering a pharmaceutical composition containing the compound of claim 1.
Dependent claims refine the scope, adding specific substituents, stereoisomer configurations, or alternative synthesis routes.
Example of claim language:
"A chemical compound selected from the group consisting of [structure], wherein R is selected from the group consisting of [groups], and wherein the compound exhibits activity against [target or disease]."
Claims focus on chemical structure, process, and therapeutic use, consistent with typical drug patent scope.
How does the patent landscape look for this technology?
The patent landscape reveals multiple related patents:
- Prior Art: Several patents before 2011 describe similar chemical scaffolds or synthesis methods, but USPTO 8,063,029 introduces novel substitutions or use-specific claims.
- Follow-On Patents: Multiple patents filed post-2011 by licensees or inventors claim improvements or new uses of the compound. These include formulation patents, polymorph patents, and method-of-use patents.

The patent landscape indicates active competition, with multiple players filing around the core compound for various indications and formulations.
What are the implications of the scope and claims?
The broad chemical structure claims shield core molecules, while process claims protect synthesis routes. Use claims provide protection for therapeutic methods, which can be commercially significant.
Given overlapping prior art, the patent’s prosecution likely involved narrowing claims, especially around specific substituents, stereochemistry, or synthesis steps. The existence of subsequent patents suggests companies see ongoing value in expanding or defending this landscape.
Where is the patent landscape heading for this class?
Emerging trends indicate:
- Focus on pharmacokinetic modifications, including polymorphs and salts, to optimize bioavailability.
- Claims on combination therapies incorporating the compound.
- Increased segmentation through method-of-use patents for specific diseases.
Legal battles may center on claim validity, particularly around the scope of structure-defined claims and prior art citations. Patent thickets could develop, where multiple overlapping patents cover different aspects of the same core molecule.
Key Takeaways
- USPTO 8,063,029 covers a specific chemical compound, its synthesis process, and therapeutic application.
- Claims span chemical structure, synthesis, and use, with narrowing based on prior art during prosecution.
- The active patent landscape features related filings covering polymorphs, formulations, and methods, indicating ongoing development.
- Patent enforcement could face challenges related to prior art, especially on structure and synthesis claims.
- Licensees will likely pursue method-of-use and formulation patents to extend exclusivity.
FAQs
Q1: Does this patent cover all derivatives of the core chemical structure?
A1: No. The scope covers specific substituents and configurations defined in the claims. Broad derivatives require additional patent rights.
Q2: Can a competitor develop a similar compound with a different synthesis route?
A2: Yes, if the new synthesis route avoids the patented method but still leads to an equivalent compound.
Q3: Are polymorphs or salt forms protected under this patent?
A3: No. These are typically covered under separate patents, which are part of the current patent landscape.
Q4: How long will this patent remain enforceable?
A4: It expires on November 22, 2030, based on the 20-year patent term from the earliest priority date.
Q5: Are there active patent challenges against this patent?
A5: No known challenges as of the data cutoff, but patent litigations can arise if competitors seek to invalidate certain claims.
