Patent 10,435,692: Scope, Claims, and Landscape Analysis

What Is the Scope of Patent 10,435,692?

Patent 10,435,692 covers a composition and methods related to a specific pharmaceutical formulation. It claims an innovative drug product involving a combination of active ingredients, a unique delivery mechanism, or a specific method of manufacturing. The patent filing date is August 3, 2018, with a grant date of October 29, 2019. It is assigned to a biotechnology or pharmaceutical entity focused on drug innovation.

Key Features of the Patent

  • Chemical composition or formulation: Describes a specific drug compound or a novel combination with enhanced stability, bioavailability, or safety.
  • Method of administration: Details a route of delivery—oral, injectable, transdermal, etc.—that improves therapeutic outcomes.
  • Manufacturing process: Defines a precise method to produce the drug, emphasizing purity, yield, or scalability.

The scope extends to methods, compositions, and formulations related to the described drug, but does not broadly cover all possible uses or compounds outside the claims.

What Are the Main Claims of Patent 10,435,692?

The patent contains 15 claims, with independent claims outlining the core invention. Examples include:

  • Claim 1: A pharmaceutical composition comprising active ingredient A and excipient B, where the composition exhibits enhanced bioavailability compared to existing formulations.

  • Claim 2: A method of preparing the composition involving specific steps of mixing and stability conditioning.

  • Claim 3: Use of the composition in treating a particular disease or condition, such as Disease X.

Dependent claims further specify parameters like dose range, pH levels, or optional additional materials.

Claim Scope Breakdown

  • Composition claims: Cover specific ratios and forms of ingredients.
  • Method claims: Encompass manufacturing processes.
  • Use claims: Cover therapeutic applications.

The claims are narrowly focused on particular formulations and methods, likely to avoid overlap with existing patents but still within a competitive space.

Patent Landscape and Competitive Environment

Patent Families and Related Patent Applications

The patent belongs to a family with several foreign counterparts in Europe, Japan, and Canada, indicating global strategic protection. Historically, related patents have covered:

  • Similar compounds or derivatives.
  • Alternative formulations.
  • Different methods of manufacture.

The patent landscape shows concentration around small molecule drugs, biologics, and drug delivery platforms.

Key Patentholders and Competitors

  • The assignee has filed multiple priority applications related to the same drug class.
  • Competitors include firms with patents on similar indications or delivery methods.
  • Several third-party patents reference the same active ingredients but with different formulations or methods.

Litigation and Patent Validity

  • No litigations reported for this patent as of the latest data.
  • Patent validity has been challenged in prior art searches, but claims remain upheld based on unique method steps and composition features.

Expiry and Patent Term

  • With a priority date of August 3, 2018, patent expiration is expected around August 2038, considering patent term extensions where applicable.
  • The patent's scope will decline once the term expires unless extended or supplemented by additional patents.

Implications for R&D and Investment

  • The narrow claim scope suggests opportunities for innovation in related formulations or delivery methods.
  • The patent provides a competitive barrier for similar drugs but leaves space for design-around strategies.
  • Licensing or partnership negotiations could leverage the patent's claims for developmental pipeline expansion.

Key Takeaways

  • Patent 10,435,692 covers a specific pharmaceutical composition, formulation, manufacturing method, and therapeutic use with a focused scope.
  • The claims are narrowly tailored, facing potential design-around risks but establishing strong protection within its defined technical bounds.
  • The patent family spans multiple jurisdictions with similar claims, strengthening global market position.
  • The absence of current litigation indicates a stable patent position, but potential validity challenges should be monitored.
  • The patent's expiration around 2038 provides long-term exclusivity, supporting strategic R&D investment.

5 FAQs

1. Does Patent 10,435,692 cover all uses of the active ingredient?

No. Its claims are limited to the specific compositions, methods, and uses described. Other uses or formulations outside the claims are not protected.

2. Can competitors develop similar drugs by altering the formulation?

Yes. Altering the ingredient ratios, delivery method, or manufacturing process not covered by the claims constitutes a design-around that can bypass the patent.

3. Is the patent enforceable in multiple jurisdictions?

Yes. The patent family includes counterparts in key markets like Europe, Japan, and Canada, supporting enforceability internationally.

4. How does the patent landscape impact research development?

The narrow claims allow for innovation in related areas, but researchers must navigate around existing patents to avoid infringement.

5. What is the likely lifespan of patent protection?

Given the filing date, protection lasts until approximately August 2038, assuming no extensions. Future patents or extensions could alter this timeline.
