Analyzing the Scope and Claims of United States Patent 10,213,386
Introduction
United States Patent 10,213,386, like many patents, is a complex document that outlines the intellectual property rights for a specific invention. This patent, in particular, protects the drug IMBRUVICA, a crucial medication in the pharmaceutical industry. Here, we will delve into the details of this patent, including its scope, claims, and the broader patent landscape it operates within.
Overview of IMBRUVICA and Patent 10,213,386
IMBRUVICA is a medication used to treat certain types of cancer, including mantle cell lymphoma, chronic lymphocytic leukemia, and Waldenström's macroglobulinemia. The patent in question, 10,213,386, is one of several patents that protect this drug, ensuring the exclusivity of its manufacture and distribution for a specified period.
Patent Claims
The claims section of a patent is critical as it defines the scope of the invention and what is protected by the patent. For Patent 10,213,386, the claims are detailed and specific, outlining the chemical composition, method of use, and any other aspects that distinguish IMBRUVICA from other drugs.
- Independent Claims: These are the broadest claims that define the invention. For IMBRUVICA, these might include the specific molecular structure of the active ingredient and the method of its administration.
- Dependent Claims: These claims are narrower and depend on the independent claims. They might include specific dosages, formulations, or methods of treatment that are variations of the broader independent claims[4].
Patent Scope
The scope of a patent is determined by its claims and the description provided in the patent specification. For Patent 10,213,386, the scope includes:
- Chemical Composition: The patent specifies the exact chemical structure of IMBRUVICA, which is a Bruton's tyrosine kinase (BTK) inhibitor.
- Method of Use: The patent details how IMBRUVICA is used to treat specific types of cancer, including the dosages and administration methods.
- Formulations: The patent may also cover various formulations of IMBRUVICA, such as capsules or tablets, and any specific manufacturing processes[4].
Patent Landscape and Terminal Disclaimers
The patent landscape for pharmaceuticals, particularly for drugs like IMBRUVICA, is complex due to the practice of obtaining multiple patents to extend exclusivity periods. This practice is known as "patent thickets."
- Patent Thickets: These are clusters of patents that protect a single product or technology. For IMBRUVICA, there are 41 patents listed in the Orange Book, with 31 of these being terminally disclaimed. This means that 75% of the remaining patents are duplicative, aimed at delaying generic and biosimilar entry into the market[1].
- Terminal Disclaimers: These are disclaimers made by the patent holder to ensure that the term of a later-filed patent does not extend beyond the term of an earlier-filed patent. The USPTO's proposed rule aims to link the enforceability of terminally disclaimed patents, reducing the incentive for brands to amass large numbers of questionable patents[1].
Impact on Generic and Biosimilar Drugs
The practice of obtaining multiple patents, including terminally disclaimed ones, significantly impacts the entry of generic and biosimilar drugs into the market.
- Delayed Market Entry: The sheer number of duplicative patents drives up costs and reduces the efficiency of patent litigation and path clearing for generic and biosimilar firms. This leads to delayed market entry of these drugs in the US compared to other countries[1].
- Exclusivity Periods: For new biological drug products, brands are entitled to a 12-year period of marketing exclusivity. For new small molecule drugs, the FDA may not approve a generic version for at least five years. The use of patent thickets extends these exclusivity periods, limiting competition[1].
Economic and Regulatory Implications
The economic and regulatory implications of these practices are significant.
- Costs and Efficiency: The accumulation of duplicative patents increases costs for generic and biosimilar firms, reducing the efficiency of the patent system. This can lead to higher drug prices and reduced access to affordable medications[1].
- Regulatory Proposals: The USPTO's proposed rule aims to rebalance the system by linking the enforceability of terminally disclaimed patents. This proposal encourages brands to obtain high-quality, innovative patents rather than amassing questionable secondary patents[1].
Case Studies and Examples
To illustrate the impact of these practices, let's consider the example of IMBRUVICA.
- IMBRUVICA Patents: As mentioned, there are 41 patents listed for IMBRUVICA, with 75% of these being terminally disclaimed. This creates a complex landscape that delays the entry of generic and biosimilar versions of the drug[1].

Conclusion
The analysis of United States Patent 10,213,386 reveals a complex interplay between patent claims, scope, and the broader patent landscape. The practice of obtaining multiple patents, including terminally disclaimed ones, has significant economic and regulatory implications, particularly in delaying the entry of generic and biosimilar drugs.
