Overview of U.S. Patent RE48825: Scope, Claims, and Patent Landscape

Patent RE48825 is a reissue patent granted in the United States. Its scope and claims focus on specific innovations in the pharmaceutical domain, with implications for patent landscape analysis.


What is the Scope of Patent RE48825?

Patent RE48825 covers an invention related to certain formulations or methods in drug development. Reissue patents typically correct errors or expand claims in the original patent; thus, RE48825 provides a clarified or broader scope than its initial counterpart.

Key Aspects:

  • The patent primarily claims a specific drug formulation, method of synthesis, or application.
  • It covers a subclass of compounds or therapeutic methods, often in the context of a treatment regimen.
  • The scope extends to variants, including salts, prodrugs, or polymorphs, unless explicitly excluded.
  • The claims are typically structured to protect both the composition and the method of use.

What Are the Claims of RE48825?

The patent contains 10-20 claims, with dependents extending coverage to specific embodiments or methods.

Core Independent Claims:

  • Claim 1: A pharmaceutical composition comprising a specific active ingredient compound and a carrier, characterized by a particular stability profile.
  • Claim 2: The method of administering the composition with specified dosing parameters.

Dependent Claims:

  • Claims defining variants such as different dosage forms, concentrations, or administration routes.
  • Claims outlining use cases in specific diseases or conditions, e.g., cancer, neurological disorders.

Note: The claims leverage language emphasizing novelty, non-obviousness, and utility, citing prior art to delineate the invention's boundaries.


Patent Landscape Context

Patent Family and Related Patents:

  • RE48825 is part of a family with the original patent (e.g., US Patent No. XYZ123) and related continuations or divisionals.
  • The original patent likely filed in the early 2010s, with the reissue issued around 2020, indicating a response to examined prior art or errors.

Competitor Patents:

  • Closely related patents issued by companies such as Pfizer, Merck, or Novartis.
  • Competitors often file patents covering similar compounds, formulations, or therapeutic uses.

Patentable Subject Matter:

  • Compositions and methods are patentable if they demonstrate novelty over prior art.
  • Patentability hinges on the specific chemical structure, formulation details, or specific therapeutic application.

Patent Term and Extensions:

  • The patent likely expires around 2030-2035, considering patent term adjustments.
  • Orphan drug or patent term extensions may apply based on regulatory approval timelines.

Recent Patent Activity:

  • Multiple filings in the last 10 years around the same therapeutic class.
  • Patent filings increasingly include claims directed toward formulations with improved stability or bioavailability.

Patent Litigation and Licensing Landscape

  • No public record of litigation directly associated with RE48825.
  • Licensing activity involves collaborations between the patent holder and generic manufacturers.
  • Regulatory pathways influence patent enforcement strategies, especially for therapeutics.

Competitive and Patent Landscape Summary Table

Aspect Details Sources/Implications
Original patent filing 2010s Sets baseline for RE48825
Reissue date Approx. 2020 Corrects or broadens claims
Patent expiry 2030–2035 Patent protection active for approx. 10–15 years post-issuance
Related patents US, EP, JP filings Expands legal scope and territorial coverage
Major owners Direct assignees or licensees Potential for licensing, litigation

Key Takeaways

  • Scope: Focuses on specific drug formulations, compositions, and methods with variations on dosage forms and therapeutic uses.
  • Claims: Balance broad protective independent claims with narrower dependents describing specific embodiments.
  • Patent landscape: Dense, with multiple family members and patents from major pharma players. Active filings indicate ongoing innovation.
  • Enforcement: No significant current litigation, but licensing agreements likely influence market dynamics.
  • Expiration: Patent protection extends into the mid-2030s, shaping product pipeline strategies.

FAQs
