Understanding the Scope and Claims of United States Patent 10,039,745
Introduction
United States Patent 10,039,745 is a significant patent in the pharmaceutical sector, particularly related to drug formulations. To analyze its scope and claims, it is essential to delve into the patent's details, the legal context, and the broader patent landscape.
Patent Overview
Patent Number and Title
The patent in question is U.S. Patent No. 10,039,745. While the specific title is not provided in the sources, it is associated with enalapril maleate formulations, as seen in related litigation documents[2][5].
Claims and Scope
Claim Structure
Patent claims are the heart of any patent, defining the scope of protection. For U.S. Patent 10,039,745, the claims would typically include independent and dependent claims. Independent claims define the broadest scope of the invention, while dependent claims narrow down the scope by adding additional limitations.
Metrics for Measuring Scope
Research suggests that the scope of a patent can be measured using metrics such as independent claim length and independent claim count. Patents with narrower claims, as indicated by shorter independent claim lengths and fewer independent claims, tend to have a higher probability of grant and a shorter examination process[3].
Legal Context and Litigation
Azurity Pharms., Inc. v. Bionpharma Inc.
This patent was involved in a significant litigation case, Azurity Pharms., Inc. v. Bionpharma Inc.. Azurity alleged that Bionpharma's proposed generic enalapril product would infringe on Azurity's patents, including U.S. Patent No. 10,039,745. The court's decision hinged on whether the generic product contained a buffer required by the patent claims. The court found that the generic product did not contain the buffer, thus not infringing on the patents[2].
Claim Preclusion
The litigation also highlighted the issue of claim preclusion. Azurity argued that the claims in the second lawsuit were not the same as those in the first, as they did not require a buffer. The court agreed, distinguishing the test for claim preclusion from the test for obviousness-type double patenting[2].
Patent Landscape

U.S. Patent No. 10,039,745 is part of a family of patents related to enalapril maleate formulations. Other patents in this family include U.S. Patents Nos. 9,669,008, 9,808,442, 10,154,987, 10,772,868, and 10,786,482. These patents collectively protect various aspects of the drug formulation and its manufacturing process[2][5].
Global Patent System
The patent landscape is not limited to the U.S. but is part of a global system. Tools like the Global Dossier and the Common Citation Document (CCD) facilitate the search and analysis of related patents across different jurisdictions. This is crucial for understanding the broader scope of protection and potential infringement risks[1].
Patent Licensing and Monetization
Examiner Rejection Analysis
Patent licensing opportunities can be identified using tools like PatentAdvisor's Examiner Rejection Analysis. This feature leverages citation data to spot potential licensing partners, competitors, and infringers. By analyzing examiner citations, patent professionals can uncover new technology spaces and mitigate infringement risks[4].
Monetization Strategies
The value of a patent like U.S. Patent No. 10,039,745 lies not only in its legal protection but also in its potential for monetization. Patent prosecution analytics can help in identifying licensing opportunities and enhancing the overall monetization strategy of the patent portfolio[4].
