Patent Scope and Breadth
Patent Scope Measurements
The USPTO's Patent Claims Research Dataset provides insights into patent scope measurements. This dataset, which includes data from patents granted between 1976 and 2014, helps in understanding the breadth and depth of patent claims. For US10,426,787B2, the scope is defined by the combination of a corticosteroid and a retinoid, which is a specific yet valuable niche in psoriasis treatment[3].
Prior Art and Novelty
The patent's validity depends on its novelty and non-obviousness over prior art. The prior art keywords listed include "psoriasis," "composition," and "tazarotene," indicating that the patent office considered existing treatments and compositions in the field. The combination of a corticosteroid and a retinoid in a single topical composition is what sets this patent apart from prior art[4].
Patent Landscape
Global Patent Family
Using the Global Dossier service provided by the USPTO, one can access the file histories of related applications from participating IP Offices. This helps in understanding the global patent family and any corresponding patents or applications in other jurisdictions[1].
Citation Data
The Common Citation Document (CCD) application consolidates prior art citations from multiple patent offices, providing a comprehensive view of the prior art landscape for this patent. This tool is essential for assessing the patent's validity and identifying potential challenges[1].
Legal and Regulatory Considerations
Presumption of Validity
United States patents are accompanied by a presumption of validity, which means that the patent is assumed to be valid unless proven otherwise. This presumption is significant in legal proceedings, such as inter partes review (IPR) or district court challenges[2].
Potential Challenges
The patent could face challenges through IPR petitions or district court litigation. For instance, if a competitor argues that the claims are anticipated by prior art or lack written description, the patent's validity could be questioned. The Federal Circuit's decisions on claim construction and indefiniteness would be crucial in such cases[2].
Economic and Practical Implications
Market Impact
The approval and enforcement of this patent can significantly impact the market for psoriasis treatments. It could lead to new therapeutic options for patients and influence the competitive landscape among pharmaceutical companies.
Licensing and Collaboration
The patent holder may choose to license the technology to other companies, which could lead to further innovation and broader availability of the treatment. Collaborations between pharmaceutical companies and research institutions could also be facilitated by the patent[4].
