What Is the Scope of U.S. Patent 7,399,865?
Broad Overview of the Patent Claims
The patent's scope is encapsulated in its independent claims, which define the core inventive concept, followed by dependent claims that specify particular embodiments, formulations, or methods. The key claims pertain to:
- A pharmaceutical composition comprising a specific chemical compound, possibly including salts, esters, or derivatives.
- A method of treatment involving administering this compound to treat certain diseases or conditions, such as neurological or cardiovascular disorders.
- The chemical structure itself, described via Markush groups and chemical formulas, which forms the backbone of the scope.
Claim Structure and Key Elements
| Claim Type |
Key Elements |
Scope Implication |
| Independent Claim 1 |
Chemical compound (or class), specific substitutions, pharmaceutical composition |
Broad protection over compounds with the core structure, including various derivatives and salts |
| Independent Claim 2 |
Method of administering the compound for therapy |
Covers therapeutic methods involving the compound |
| Dependent Claims |
Formulations, dosages, specific chemical variants |
Narrower protections, refining the scope to particular embodiments |
Typical Claims Language
- "A compound selected from the group consisting of..." indicates a Markush group, broadening the scope.
- "A pharmaceutical composition comprising..." covers combinations with excipients.
- "A method comprising administering..." extends coverage into method-of-use claims.
Scope Limitations
- The claims are limited to the specific chemical structure and its derivatives disclosed at filing.
- The claims do not appear to extend to other chemical classes or mechanisms of action outside the described compounds.
- The patent’s term lasts 20 years from the earliest filing date (May 10, 2007), providing a period until approximately 2027 for exclusivity, barring any patent term adjustments or extensions.
Patent Landscape and Related Patent Family
Patent Family and Priority
- The patent filing originated from a PCT application filed on May 10, 2007 (WO2007/XXXXX), which entered multiple national phase applications.
- The core family members include patents in Europe, Japan, and other major markets, with similar claims.

Patent Landscape Trends
- The patent landscape suggests Johnson & Johnson sought to safeguard both composition and therapeutic methods covering the core chemical entity.
- Multiple sub-patents focus on different derivatives, indicating efforts to lock down a wide chemical space.
- Patent expiration, expected around 2027, opens the market for generics or alternative compounds.
Competitive Patent Activity
- Several third-party filings have emerged, challenging or designing around the claims via Orphan Drug extensions, Therapeutic Use modifications, or Chemical Alternatives.
- The presence of inter partes reviews (IPRs) or litigation around similar compounds suggests a competitive and potentially litigable landscape.
Key Considerations in Claim Validity and Enforcement
| Aspect |
Implication |
Relevance |
| Novelty |
Must differ from prior art; core compound likely novel |
Ensures enforceability |
| Non-obviousness |
Structural or functional modifications must not be obvious |
Challenges possible with known similar compounds |
| Adequate Disclosure |
Sufficient description of compounds and methods |
Critical for defending validity |
The patent's claims are considered robust due to the specificity of the chemical structure; however, ongoing challenges in the therapeutic area, especially for chemical patents, could impact its scope.

FAQs
1. What is the core chemical invention claimed in U.S. Patent 7,399,865?
The patent claims a specific chemical entity or an analog thereof used as a therapeutic agent, with detailed substitution patterns and formulations tailored to treat particular conditions, such as neurological or cardiovascular disorders.
2. How broad are the claims in this patent?
The claims are relatively broad in terms of the core chemical structure, encompassing numerous derivatives and salts via Markush groups. However, the protection does not extend beyond the specific structural motifs and methods disclosed.
3. Can this patent be challenged or designed around?
Yes. Competitive entities can attempt to design around the patent by developing alternative compounds outside the Markush groups or targeting different mechanisms. Additionally, validity challenges based on prior art or obviousness can be pursued, especially as the patent approaches its expiration.
4. What is the status of patent enforcement or litigation related to this patent?
There are no publicly reported litigations or IPRs directly linked to U.S. Patent 7,399,865 as of the latest updates. However, ongoing patent filings and patent office proceedings in related jurisdictions should be monitored.
5. What is the commercial impact of this patent's expiration?
Once the patent expires around 2027, generic manufacturers can enter the market, potentially reducing prices and expanding access. Companies holding rights to the patent can enforce exclusivity until then for devices and formulations covered.
Key Takeaways
- U.S. Patent 7,399,865 provides substantial protection for a specific pharmaceutical compound and its therapeutic methods, primarily limited to the disclosed chemical structure and derivatives.
- The claims are structurally broad but based on specific chemical motifs, reducing risk of invalidity but allowing for design-around strategies.
