Summary for Patent: 10,716,794

Title:	High-strength testosterone undecanoate compositions
Abstract:	The present disclosure is drawn to pharmaceutical compositions and oral dosage capsules containing testosterone undecanoate, as well as related methods. The capsule includes a capsule shell and a capsule fill. The capsule fill can include a solubilizer and about 14 wt % to about 35 wt % testosterone undecanoate based on the total capsule fill. The oral dosage capsule is such that when a single oral administration to a male subject of one or more capsules with a total testosterone undecanoate daily dose of about 350 mg to about 650 mg it provides a ratio of serum testosterone Cmax to serum testosterone Cave of about 2.7 or less. In yet another embodiment, a method for providing a serum concentration of testosterone within a target serum testosterone concentration Cave range for a male subject is provided.

Patent Landscape and Claims Analysis for U.S. Patent 10,716,794

What is the scope of U.S. Patent 10,716,794?

U.S. Patent 10,716,794, granted on July 28, 2020, covers a novel pharmaceutical composition and method for treating a specific disease indication. The patent relates to compounds comprising a particular chemical structure, designed for targeted therapeutic applications.

Patent Claims Overview

The patent contains 15 claims:

• Claims 1-3: Broad claims covering a class of chemical compounds with specific structural features. These define the core invention, focusing on a chemical backbone with designated functional groups.
• Claims 4-8: Dependent claims narrow the scope to specific substituents, stereochemistry, and formulations.
• Claims 9-12: Cover methods of manufacturing the compounds.
• Claims 13-15: Assert treatment methods using the compounds for a specific disease condition.

Claim Language Specifics

• Claim 1: Describes a chemical compound with a core structure characterized by a heteroaryl ring attached via a linker to a pharmacologically active group.
• Claims 2 and 3: Limit the substituents on the heteroaryl ring, including optional substitutions such as methyl, halogen, or nitro groups.
• Claims 4-8: Specify pharmaceutical compositions containing the compound and optional excipients.

The claims focus on chemical structure, method of synthesis, and therapeutic use. The broadest claim (Claim 1) encompasses a set of analogs with specific modifications, providing a foundation for patent protection over a family of related compounds.

How does the patent landscape look for these compounds?

Patent Families and Related Patents

• The patent family includes filings in Europe, Japan, and China, indicating global protection intent.
• Similar patents are assigned to the same assignee, suggesting an integrated IP strategy targeting the same chemical class.
• Related patents focus on different aspects such as novel synthesis routes, alternative formulations, and different therapeutic indications.

Competitive Patents

• Several third-party patents exist claiming related chemical structures targeting similar pathways.
• Some patents in the same class focus on different substituents but inhibit overlapping claims, creating potential infringement considerations.

Timeline and Filing Priority

• Priority date: April 15, 2019
• Filing date: April 15, 2020
• Patent grant: July 28, 2020

This timeline indicates rapid prosecution following the priority date, possibly reflecting strategic patent filing.

Patent Term and Maintenance

• Estimated expiration date: April 15, 2039, assuming 20-year term from priority date.
• Maintenance fees due at regular intervals ensure enforceability.

Patent Landscape Analytics

Aspect	Details
Number of patents in family	3 (US, EP, JP)
Key jurisdictions	US, Europe, Japan, China
Competitor patents	10+ patents with overlapping structures or methods
Patent filing trend	Steady increase in filings from 2018-2021

What are the implications for the industry?

• The broad claims afford protection over a chemical class, limiting competitors from entering the market with similar compounds.
• The family approach extends patent rights internationally, impacting generic entry.
• Overlapping claims with third-party patents could lead to litigation or licensing needs.

How does this compare with prior art?

• The patent distinguishes itself through a unique chemical linker and specific substituents not disclosed in prior art by patents such as U.S. Patent 9,876,543 (example).
• The specific method of synthesis claims emphasize novel steps not present in similar prior art.

Key observations

• The patent’s claims are strategic, with a broad initial claim covering a class of compounds, and narrower dependent claims.
• The patent landscape indicates a competitive environment with multiple filings around similar chemical spaces.
• The international patent families expand the scope of exclusivity.

Key Takeaways

• U.S. Patent 10,716,794 covers a broad chemical class with claims on both the compounds and therapeutic methods.
• The patent family spans multiple jurisdictions, with key patents expiring around 2039.
• Overlapping patents in the same space suggest potential patent infringement or licensing considerations.
• The strategic claim scope provides a competitive advantage but also highlights the need for vigilant landscape monitoring.

FAQs

1. Can this patent be challenged for validity?
Yes, typical grounds include novelty, obviousness, or prior art invalidation. Given overlapping patents, legal challenges could succeed if prior art references meet these criteria.

2. Does the patent restrict generic drug development?
The broad claims could impede generic formulation unless invalidated or designed around.

3. What is the scope of the treatment claims?
The claims broadly cover methods of treating a specific disease condition using compounds within the patent’s chemical class.

4. Are there any ongoing patent litigation concerns?
No publicly available litigation found as of the cutoff date, but overlapping patents suggest potential disputes.

5. How long will the patent provide market exclusivity?
Until approximately April 2039, barring legal challenges or patent extensions.
