United States Patent 11,197,847: A Detailed Analysis of Scope, Claims, and Patent Landscape

Introduction

United States Patent 11,197,847, titled "Isoxazoline parasiticide formulations and methods for treating parasites," is a significant patent in the field of veterinary medicine and parasitology. This patent, granted on December 14, 2021, protects formulations and methods related to isoxazoline parasiticides. Here, we will delve into the scope, claims, and the broader patent landscape surrounding this invention.

Patent Overview

Title and Abstract

The patent titled "Isoxazoline parasiticide formulations and methods for treating parasites" focuses on novel formulations and treatment methods using isoxazoline compounds. These compounds are known for their efficacy against various parasites in animals, particularly ticks, fleas, and other ectoparasites.

Background

Isoxazoline compounds have gained prominence in recent years due to their potent parasiticidal activity and safety profile. This patent builds upon existing research and development in the field, offering improved formulations and treatment regimens.

Scope of the Patent

Claims

The patent includes multiple claims that define the scope of the invention. Here are some key aspects:

  • Claim 1: This claim describes the composition of the isoxazoline parasiticide formulation, including the active ingredients, excipients, and the method of administration.
  • Claim 2-5: These claims specify different embodiments of the formulation, such as varying concentrations of the active ingredients and different forms of administration (e.g., topical, oral).
  • Claim 6-10: These claims cover the methods of treating parasites using the isoxazoline formulations, including the dosage regimens and the types of parasites targeted[5].

Dependencies and Continuations

The patent is a continuation application of U.S. patent application Ser. No. 17/099,531, filed on October 28, 2020. This indicates that the current patent builds upon previous work and may incorporate new developments or improvements over the earlier application[5].

Patent Family and International Coverage

Patent Family

The patent has sixteen patent family members in thirteen countries, indicating a broad international protection strategy. This is crucial for ensuring global market exclusivity and preventing unauthorized use of the invention in various jurisdictions[2].

International Patent Offices

The protection of this patent is not limited to the United States. It is part of a larger global patent strategy, with filings in multiple countries. This is facilitated by international patent databases and services such as the European Patent Office's esp@cenet, the Japan Patent Office, and the World Intellectual Property Organization's PATENTSCOPE[1].

Patent Landscape

Related Patents and Prior Art

To understand the patent landscape, it is essential to identify related patents and prior art. Tools like the Common Citation Document (CCD) and the Patent Public Search tool provided by the USPTO can help in this regard. The CCD consolidates prior art cited by all participating IP5 Offices, providing a comprehensive view of the prior art landscape for the same invention[1].

Competitors and Market Impact

The isoxazoline market is competitive, with several other companies and researchers working on similar compounds. The grant of this patent provides the holder with a competitive edge, allowing them to market and sell their formulations exclusively. This can significantly impact the market, particularly in the veterinary pharmaceutical sector.

Economic and Legal Implications

Allowance Rates and Examination Process

The probability of receiving a patent, especially in the chemical and pharmaceutical fields, can be complex due to the rigorous examination process. The USPTO's internal databases and the Patent Application Information Retrieval (PAIR) system provide insights into the examination outcomes and continuation procedures, which are crucial for understanding the patent's validity and scope[4].

Small vs. Large Entities

Research indicates that patent applications filed by small entities are less likely to be granted compared to those filed by large entities. This patent, being part of a larger family with international coverage, suggests that it is likely filed by a larger entity with significant resources[4].

Key Takeaways

  • Patent Scope: The patent covers specific isoxazoline parasiticide formulations and treatment methods.
  • Claims: Multiple claims define the composition, method of administration, and treatment regimens.
  • International Coverage: The patent has a broad international protection strategy with filings in thirteen countries.
  • Market Impact: The patent provides a competitive edge in the veterinary pharmaceutical market.
