Patent Title and Description
The patent titled "Preparation containing tetracyclic compound at high dose" focuses on specific formulations of the active ingredient in Alecensa. This patent covers the preparation and composition of the drug, ensuring that only the patent holder can produce and market products using this particular formulation until the patent expires in April 2035[4].
Scope of the Patent
Claim Language and Scope
The scope of a patent is defined by its claims, which outline the specific inventions or innovations protected. For US 10,350,214, the claims would typically include detailed descriptions of the tetracyclic compound, its high-dose preparation, and any specific methods of use or administration.
- Independent Claim Length and Count: Research suggests that the length and count of independent claims can be indicative of the patent's scope. Narrower claims, often resulting from a more rigorous examination process, are associated with a higher probability of grant and shorter examination times[3].
Exclusivity and Market Protection
This patent, along with others associated with Alecensa, provides exclusivity to Hoffmann-la Roche Inc., preventing generic competitors from entering the market until the patents expire. This exclusivity period is crucial for the pharmaceutical company to recoup its significant investment in research and development.
Claims and Their Impact
Types of Patents Listed
Patents like US 10,350,214 can be categorized into several types, including drug substance patents, drug product patents, and method-of-use patents. Each type of patent has a different impact on the timing of generic competition:
- Drug Substance Patents: These patents protect the active ingredient itself.
- Drug Product Patents: These cover the formulation or composition of the drug.
- Method-of-Use Patents: These protect specific methods of using the drug[1].
Examples of Patent Claims
For Alecensa, the patent claims would include specifics about the tetracyclic compound and its high-dose preparation. Here is an example of how such claims might be structured:
- "A pharmaceutical composition comprising a tetracyclic compound at a high dose, wherein the composition is used for the treatment of lung cancer."
- "A method of treating lung cancer using a pharmaceutical composition containing a tetracyclic compound at a high dose."
These claims define the scope of the patent and the rights of the patent holder.
Patent Landscape and Generic Competition
Orange Book Listings
Patents associated with Alecensa, including US 10,350,214, are listed in the FDA's Orange Book. This listing is crucial for generic drug manufacturers, as it provides them with the necessary information to determine when they can file an Abbreviated New Drug Application (ANDA) and potentially launch a generic version of the drug[1].
Follow-On Innovations
The patent landscape for Alecensa also includes follow-on innovations, such as new dosage forms or methods of treatment. These follow-on patents can extend the exclusivity period even after the initial patents have expired. For example, patents covering once-daily dosage forms or new indications can delay generic competition[1].
Litigation and Settlements
Patent disputes in the pharmaceutical industry often lead to litigation and settlements. These settlements can allow generic manufacturers to enter the market earlier than the patent expiration date, subject to certain conditions. For instance, settlements might include provisions for the generic manufacturer to launch their product at a specified date before the patent expires[2].
Economic and Regulatory Implications
Market Exclusivity
The duration of market exclusivity for drugs like Alecensa can range significantly, from about 3 to 16 years, depending on the patents and exclusivities in place. This period is critical for the pharmaceutical company to generate revenue and recoup investment costs[1].
Regulatory Environment
The regulatory environment, including Executive Orders and FDA policies, influences the patent landscape. For example, Executive Order 14036 emphasizes promoting generic drug and biosimilar competition to lower drug prices and improve access[1].
Conclusion
The United States Patent 10,350,214 is a key component of the patent landscape for Alecensa, protecting specific formulations of the drug's active ingredient. Understanding the scope and claims of this patent, along with the broader patent landscape, is essential for both pharmaceutical companies and generic manufacturers.
