Here, we will delve into the scope, claims, and the broader patent landscape surrounding this invention.
Background of the Patent
The patent was granted on September 11, 2013, to inventors such as Streetly et al., and it pertains to methods for treating multiple myeloma, a type of blood cancer, using CC-4047, a thalidomide analogue[2].
Scope of the Patent
The scope of the patent is defined by its claims, which outline the specific methods and uses of CC-4047 in treating multiple myeloma. Here are some key aspects:
Treatment Methods
The patent describes methods for treating multiple myeloma by administering CC-4047, either alone or in combination with other therapeutic agents. This includes dosing regimens and specific patient populations that can benefit from this treatment[2].
Efficacy and Safety
The patent highlights the efficacy and safety profile of CC-4047, based on clinical trials and studies that demonstrate its effectiveness in treating relapsed and refractory multiple myeloma[2].
Claims of the Patent
The claims of the patent are crucial as they define the legal boundaries of the invention. Here are some key claims:
Independent Claims
The patent includes several independent claims that describe the core methods of treatment. For example, Claim 1 might describe the method of treating multiple myeloma by administering a specific dose of CC-4047 to a patient[2].
Dependent Claims
Dependent claims further specify the methods described in the independent claims. These could include specific dosing schedules, combinations with other drugs, or particular patient groups[2].
Metrics for Measuring Patent Scope
To understand the breadth and depth of the patent, metrics such as independent claim length and independent claim count can be used. These metrics help in assessing the complexity and scope of the patent claims. For instance, narrower claims at publication are associated with a higher probability of grant and a shorter examination process, as shown in research on patent scope[3].
Patent Examination Process
The examination process for this patent would have involved a thorough review of the claims to ensure they are novel, non-obvious, and meet the requirements for patentability. The process tends to narrow the scope of patent claims, making them more specific and less broad, which is a common trend observed in patent examinations[3].
Patent Landscape
The patent landscape surrounding US Patent 8,530,498 includes several related patents and applications in the field of multiple myeloma treatment.
Related Patents
Other patents owned by Celgene or other companies may cover different aspects of thalidomide analogues or methods of treating multiple myeloma. For example, patents like those mentioned in the litigation documents involving Celgene and Hetero Pharmaceuticals, which deal with various patents related to thalidomide and its analogues, are part of this landscape[1].
