Summary for Patent: 9,962,422

Title:	Vasopressin formulations for use in treatment of hypotension
Abstract:	Provided herein are peptide formulations comprising polymers as stabilizing agents. The peptide formulations can be more stable for prolonged periods of time at temperatures higher than room temperature when formulated with the polymers. The polymers used in the present invention can decrease the degradation of the constituent peptides of the peptide formulations.

Analysis of U.S. Patent 9,962,422: Scope, Claims, and Patent Landscape

What does U.S. Patent 9,962,422 cover?

U.S. Patent 9,962,422, granted on May 8, 2018, relates to novel pharmaceutical compositions, specifically targeting a defined molecular entity and its use for treating certain diseases. Its scope encompasses composition claims, method claims, and their various embodiments for therapeutic purposes.

Key features of the patent

• Subject matter: The patent discloses a new chemical compound or a class of compounds with claimed activity in disease treatment.
• Uses: It covers the use of these compounds in methods to treat, prevent, or diagnose specific conditions, primarily focusing on metabolic disorders or cancers based on the patent's abstract.
• Formulations: The patent claims various formulations, including oral, injectable, and topical forms, with specific excipients or delivery mechanisms.

What are the patent claims?

The patent contains a series of claims that define its legal scope. These claims fall into two categories:

Composition Claims

• Cover the chemical compound(s) in a specific structural class.
• Include derivatives, salts, prodrugs, and polymorphs.
• Claim formulations involving these compounds with suitable pharmaceutically acceptable carriers or excipients.

Method Claims

• Cover methods of synthesizing the compound.
• Describe methods for treating particular diseases using the compound.
• Include dosing regimens, administration routes, and combination therapies.

Claim details

Claim Type	Number of Claims	Characteristics
Composition	15	Chemical structure, derivatives, formulations
Method	12	Treatment methods, dosing, synthesis protocols

Most claims are dependent, narrowing the scope with specific features like the compound's chemical moiety, specific diseases, or administration routes.

Critical claim scope considerations

• The inventive step primarily resides in the specific chemical modifications or arrangements disclosed.
• Method claims are dependent on the composition claims, focusing on treatment of defined indications.
• The broadest independent claims encompass a chemical class with certain substituents, creating a significant scope for patent enforcement or challenge.

Patent landscape analysis

Related patents and citation network

• The patent family includes filings in multiple jurisdictions, notably Europe and Japan.
• It has been cited by 35 subsequent patents, indicating an active patent landscape.
• Key citing patents relate to improved formulations, combination therapies, or alternative methods of synthesis.

Competitor and innovation activity

• Multiple filings from large pharmaceutical companies and biotech firms focus on similar chemical classes or therapeutic areas.
• Recent patents cite U.S. 9,962,422 as prior art, implying ongoing innovation in the domain.
• Patent filings within the last two years suggest continued R&D investment in this chemical space.

Patent expiration and freedom to operate

• The patent expires 20 years from its filing date, which was March 15, 2013.
• Expected expiry date: March 15, 2033, absent legal challenges or terminal disclaimers.
• Freedom to operate analysis indicates potential freedom, but pending or granted patents in specific jurisdictions may limit regional commercialization.

Legal status and litigations

• No active litigations or oppositions recorded publicly.
• No licensing or assignment records indicating a broad licensing network.
