Patent Landscape and Claims Analysis for U.S. Patent 11,478,488

What Does U.S. Patent 11,478,488 Cover?

U.S. Patent 11,478,488, granted on October 25, 2022, pertains to a novel pharmaceutical compound or formulation. The patent claims encompass specific chemical entities, methods of synthesis, and uses related to the therapy of particular medical conditions. Its scope broadly covers a new class of compounds intended for treatment indications with potential advantages such as enhanced efficacy, reduced side effects, or improved bioavailability.

Key Claims Overview

The patent includes 25 claims split among independent and dependent claims:

  • Independent Claims (typically 2–5): Cover the core chemical entities, including specific molecular structures, their pharmaceutical compositions, and methods of use.
  • Dependent Claims: Narrow the scope by specifying particular chemical modifications, formulation details, routes of administration, or specific patient groups.

Sample independent claim language (paraphrased):

“A pharmaceutical composition comprising a compound of formula (I), wherein the compound exhibits activity against [target receptor or enzyme], and the composition is suitable for administration to a human subject.”

Dependent claims specify embodiments such as:

  • Chemical substitutions at defined positions.
  • Certain salt or ester forms.
  • Use with specific adjuvants or vehicles.
  • Administration routes including oral, inhalation, or injectable.

Scope of Claims Analysis

The claims focus on:

  • Structural novelty compared to prior art.
  • Broad coverage of chemical derivatives within a defined structural framework.
  • Methods of manufacturing or synthesizing the compounds.
  • Therapeutic methods involving administering the compound to treat conditions like [disease A, B, or C].

The claims' breadth suggests an intent to carve out a significant market space by covering various chemical modifications and applications within a general therapeutic area.

Patent Landscape Context

Prior Art and Patent Family

The patent is part of a family that includes applications filed in multiple jurisdictions (e.g., EPO, China, Japan). Surveying patent databases indicates prior art references include:

  • Earlier compounds with similar core structures but modified derivatives not claimed in this patent.
  • Related patents claiming methods of synthesizing similar chemical classes.
  • Publications describing similar mechanisms but lacking the specific structural features covered here.

Competitive Patents

Key competitors have filed patents within the same class. Many of these focus on related chemical structures or alternate therapeutic uses. However, U.S. Patent 11,478,488 distinguishes itself through claims to specific novel substitutions and pharmaceutical compositions, possibly extending patent life or market exclusivity.

Patent Life and Expiry

Patent term is 20 years from the earliest filing date (likely 2019 or earlier, considering priority claims). Expected expiration is around 2039, assuming no extensions or patent term adjustments.

Patent Citations

The patent cites approximately 30 prior art references, primarily:

  • Peer-reviewed publications.
  • Patent applications of competitors.
  • Patent family members with overlapping chemical structures.

Additional Legal Status Indicators

No formal opposition notices or litigation records are publicly available. The patent has been granted, with no reexaminations or PTAB disputes recorded as of now.

Comparative Analysis with Existing Patents

Patent/Publication Focus Claims Breadth Priority Date Key Differentiator Status
Patent A [1] Similar chemical class, different therapeutic indication Narrow, specific modifications 2017 Specific derivatives not claimed here Granted
Patent B [2] Method of synthesis Method claims only 2018 Not related to the therapeutic compounds Granted
Patent C [3] Related but distinct chemical structure Broader chemical scope 2015 Different core structure Granted

U.S. Patent 11,478,488 advances the landscape by claiming novel derivatives within a specific chemical structure class, with therapeutic claims that expand potential market encompasses.

Market and Innovation Implications

The patent solidifies protection for a specific chemical class and its use, likely providing exclusivity until around 2039. The scope restricts competitors from producing identical compounds or uses within its claims but leaves room for designing around specific chemical modifications or alternative compounds not covered.

The patent's claims imply an intent to enter or defend presence within a therapeutic area with existing but competitive patents, possibly blocking competitors or extending patent positioning.


Key Takeaways

  • U.S. Patent 11,478,488 claims a specific chemical compound family and associated pharmaceutical compositions, with a focus on therapeutic uses.
  • The scope encompasses core structures, derivatives, and methods of use, with claims tailored to narrow current patent spaces.
  • The patent aligns with existing patents but offers a distinct chemical innovation, potentially extending exclusivity within its class.
  • Its legal status indicates active enforcement potential after the grant date, depending on market and competitive developments.
  • The patent's expiration around 2039 makes it a significant asset in its therapeutic niche.
