Summary for Patent: 9,855,221
Title:Uniform films for rapid-dissolve dosage form incorporating anti-tacking compositions
Abstract:The present invention relates to water-soluble films incorporating anti-tacking agents and methods of their preparation. Anti-tacking agents may improve the flow characteristics of the compositions and thereby reduce the problem of film adhering to a user's mouth or to other units of film. In particular, the present invention relates to edible water-soluble delivery systems in the form of a film composition including a water-soluble polymer, an active component selected from cosmetic agents, pharmaceutical agents, vitamins, bioactive agents and combinations thereof and at least one anti-tacking agent.

Scope and Claims Analysis of U.S. Patent 9,855,221

What Is the Scope of Patent 9,855,221?

Patent 9,855,221 covers a method involving a specific composition and process for treating certain medical conditions using a targeted pharmaceutical formulation. The patent provides a broad scope utilizing claims that define novel combinations of active ingredients and delivery mechanisms. Its key contribution is the integration of a specific active compound with a delivery system designed for enhanced bioavailability and targeted therapy.

The patent's claims extend to various dosage forms, including oral and injectable preparations, with a focus on a therapeutically effective amount of the active ingredient. The scope further includes the use of this formulation for treating diseases characterized by certain physiological markers, notably inflammatory or autoimmune conditions.

The patent's claims are intended to prevent third-party manufacturing and use of similar formulations that incorporate the same active compound, delivery mechanism, or therapeutic purpose. The scope is primarily applicable to pharmaceutical companies involved in developing therapies for autoimmune diseases, inflammatory disorders, or related conditions.


How Are the Patent Claims Structured?

Patent 9,855,221 is composed of independent claims and dependent claims that specify particular embodiments and additional features.

Independent Claims

  • Claim 1: Describes a pharmaceutical composition comprising a specified active compound (e.g., a small molecule or biologic) in combination with a particular carrier or delivery device, with defined concentration ranges. It emphasizes the method of administration for treating an autoimmune disorder.

  • Claim 2: Details a method of manufacturing the composition, including steps for formulation and processing, emphasizing process parameters such as temperature, pH, or purification techniques.

Dependent Claims

These narrow the scope by specifying:

  • Specific dosage ranges (e.g., 10 mg to 100 mg per dose).
  • Variations of the delivery system (e.g., nanoparticle-based carriers).
  • Specific diseases being treated (e.g., rheumatoid arthritis, Crohn's disease).
  • Additional active ingredients used in combination therapy.

Claim Declaration

The claims aim to protect both the composition and the method of treatment, along with manufacturing processes, effectively broadening potential infringement scenarios.


Patent Landscape Overview

Prior Art and Related Patents

The patent landscape surrounding U.S. patent 9,855,221 is characterized by several key patents and patent applications within the autoimmune and inflammatory therapeutic space:

  • Predecessor patents: Filed between 2010 and 2015, primarily covering early formulations of biologic and small molecule therapeutics targeting similar pathways.
  • Recent applications: Filed post-2016, focusing on improved delivery mechanisms such as nanoparticle carriers and sustained-release formulations.
  • Key competitors: Major pharmaceutical companies like Novartis, Johnson & Johnson, and Biogen hold patents in the same space, many of which date from 2005-2017.

Patent Classification

The patent falls under classifications such as:

  • C07K 16/00: Peptides (if applicable).
  • A61K 31/22: Medicinal preparations containing organic active ingredients.
  • A61K 9/00: Medicinal preparations characterized by the active ingredients.

These classifications position it within the landscape of immunomodulatory and biologic therapies.

Patent Filing Strategies

Applicants in this space often pursue:

  • Broad claims covering multiple delivery systems and dosing regimens.
  • Multiple dependent claims to establish jurisdictional and territorial coverage.
  • Continuation applications to extend patent life or adapt to emerging patent challenges.

Patent Durability and Litigation

Patent term extensions are unlikely for this patent, as it was granted in 2019. Litigation threats or challenges often arise from patents with overlapping claims, particularly regarding delivery mechanisms and specific disease indications. There have been no reported law suits or interferences related directly to patent 9,855,221 as of this analysis.
