- Any specific formulations or dosages of voxelotor.
A thorough analysis of these claims helps in understanding what is protected under the patent and what would constitute infringement[3].
Claim Analysis
Specificity and Scope
The claims must be specific enough to define the invention clearly but broad enough to cover variations that could be developed by others. For example, the claims might include specific molecular structures or methods of use that are unique to voxelotor. This specificity is crucial for determining the patent's validity and its position within the industry.
Novelty and Non-Obviousness
The claims must also meet the criteria of novelty and non-obviousness. This means that the invention must be new and not obvious to someone skilled in the field. The patent office would have evaluated these aspects during the patent application process to ensure that the claims are valid and enforceable[3].
Patent Landscape Analysis
Importance of Patent Landscape
Patent landscape analysis is a comprehensive approach that goes beyond individual patent claims to provide a broader view of the intellectual property landscape. This analysis is vital for businesses seeking to innovate and expand within a crowded and evolving IP environment.
Geographical Spread and Patent Saturation
- Geographical Spread: Understanding the geographical spread of patents in a technology area is vital. For OXBRYTA, Global Blood Therapeutics Inc. would likely have filed patents in key jurisdictions to extend enforcement potential globally. This spread indicates a strategic approach aimed at global enforcement[3].
- Patent Saturation: Determining the saturation level of the specific technology patent space is critical. High saturation in the field of sickle cell disease treatments could indicate that entering this space may be challenging and costly. A comprehensive assessment of existing and pending patents, along with competitor data, guides company leadership in deciding whether to invest in this area.
Regulatory Context and Patent Term Extension
Regulatory Review Period
The regulatory review period for OXBRYTA, which includes both the testing phase and the approval phase, is a critical factor in determining the patent term extension. The FDA's determination of the length of the regulatory review period forms the basis for calculating the potential patent term extension. For U.S. Patent 10,017,491, the regulatory review period began on November 6, 2014, and the patent was issued on April 28, 2015. The extension period is calculated based on the time spent in regulatory review after the patent issuance[5].
Patent Term Extension Application
Global Blood Therapeutics Inc. has applied for patent term extension for U.S. Patent 10,017,491 based on the regulatory review period of the New Drug Application (NDA) for OXBRYTA. The application seeks an extension of up to 913 days, which is calculated based on the regulatory review period and other statutory limitations[5].
Strategic Implications
Market Dominance
The patent term extension for U.S. Patent 10,017,491 provides Global Blood Therapeutics Inc. with extended market exclusivity, allowing the company to maintain its market dominance in the treatment of sickle cell disease. This exclusivity period is crucial for recouping investment in research and development and for generating revenue.
Competitive Landscape
The patent landscape analysis helps in understanding the competitive environment. With multiple patents filed and pending, Global Blood Therapeutics Inc. has a strong intellectual property position that deters competitors from entering the market with similar products. This strategic positioning is essential for maintaining a competitive edge.
