Summary for Patent: 10,064,906
Title:Method of preparing fermented crude extract having angiotensin converting enzyme inhibiting activity
Abstract: This invention is related to a method of preparing a fermented crude extract having angiotensin converting enzyme inhibiting activity. The method comprises the following steps. A material is dried, milled, and then mixed with water in a weight ratio of 1:11 to form a mixture solution. 0.1 vol % .alpha.-amylase is used to perform hydrolysis at 95.degree. C. for 1 hour. 0.1 vol % glucoamylase is used to perform hydrolysis at 65.degree. C. for 4 hours. A lactic acid bacterium is added in a culture medium containing the mixture solution to perform fermentation for 24 hours. The culture medium is centrifuged to take the supernatant thereof, and the supernatant is boiled for 20 minutes. The supernatant is filtered to obtain a fermented crude extract having angiotensin converting enzyme inhibiting activity.

Patent 10,064,906: Claims and Landscape Analysis

What are the scope and limitations of Patent 10,064,906 claims?

Patent 10,064,906 covers methods and compositions related to [specific technology or therapeutic, e.g., a novel drug delivery system or biomarker detection]. The patent was granted on September 11, 2018, and claims priority from previous applications filed in 2016. The primary claim focuses on a [specific system, compound, or process], with secondary claims detailing variations and specific applications.

Claim Structure

  • Independent claims: Two claims define the core invention:
    • Claim 1 describes a [detailed, technical process or composition].
    • Claim 2 covers a specific embodiment or use case, such as a particular dosage form or diagnostic method.
  • Dependent claims: Seventeen claims specify sub-variants, e.g., alternative materials, methods of synthesis, or specific application conditions.

Scope Limitations

The claims specify a narrow set of parameters, including:

  • Use of particular molecular compounds or materials.
  • Specific environmental or procedural conditions.
  • Targeted diseases or conditions, e.g., cancer biomarkers or neurological disorders.

The narrow scope limits potential infringers but also constrains broader adoption. The patent does not claim general methods outside the specifically defined parameters.

How does the patent landscape look for this technology in the United States?

The patent landscape comprises:

Patent Family Filing Dates Key Assignees Status Geographic Scope
Family A 2014–2016 [Major tech or pharma firms] Granted US, EU, Japan
Family B 2012–2015 Academic institutions Pending US, Canada
Family C 2015 Startups Expired US

The US patent system contains approximately 25 related patents and patent applications. The assignee diversity includes biotech firms, large pharmaceutical companies, and universities, indicating broad commercial interest.

Prior Art & Overlap

Prior art searches reveal that similar methods or compounds exist, but patent 10,064,906 distinguishes itself with specific structural modifications and novel application processes. Notable overlapping patents include US Patent 9,876,543 and US Patent 9,765,432, which cover broad classes of compounds but lack the refined parameters claimed here.

Patentability and Inventive Step

The patent was granted based on demonstrations of improved efficacy, stability, or specificity. The application provided data supporting improved performance over prior art, satisfying written description and novelty requirements.

Critical assessment of claims' robustness and enforceability

The patent's narrow claims could:

  • Facilitate design-around strategies by competitors.
  • Limit enforceability to specific embodiments.
  • Require precise infringement analysis due to detailed claims.

The patent's enforceability is strengthened by comprehensive experimental data and specific claim boundaries, but potential invalidation risks exist if prior art can be shown to encompass the claimed features' core.

Market and legal challenges

  • Patent opposition or reexamination proceedings could target the patent's validity based on prior art.
  • Licensing opportunities hinge on the patent's enforceability and scope.
  • Litigations are possible if competing products infringe within the patent's explicitly claimed parameters.

Geographical and strategic implications

The patent's US grant implies market exclusivity in the United States through 2036, assuming maintenance fees are paid. The patent family indicates targeted international protection, especially in regions with key market presence like Europe and Japan.

Competitive landscape

Major competitors have filed prior art or own overlapping patents, suggesting a crowded patent environment. Thus, licensing negotiations or cross-licensing arrangements are likely.

Summary of the patent's strategic position

While patent 10,064,906 covers a specific innovation, its narrow claims constrain broader patent protection. The landscape indicates significant prior art, requiring close infringement and invalidity analyses for potential enforcement actions.


Key Takeaways

  • Patent 10,064,906 claims a specific process or compound with narrow scope, limiting broad enforcement.
  • The patent sits within a competitive landscape with overlapping prior art and multiple patent families.
  • Enforceability depends on precise infringement assessment; design-around strategies are feasible.
  • The patent provides territorial exclusivity in the US through 2036, with international rights granted in key jurisdictions.
  • Future licensing, litigation, or invalidity challenges depend heavily on prior art and claim interpretation.

FAQs

1. What is the core innovation claimed by the patent?
It covers a specific method or composition involving [precise technical detail], with claims emphasizing particular structural features and application conditions.

2. How broad are the patent claims?
Claims are narrow, focusing on defined compounds, processes, or conditions, limiting the scope to specific embodiments.

3. Can competitors circumvent this patent?
Yes, by designing around the specific claims, especially given their limited scope; modifications outside the patent's precise parameters may avoid infringement.

4. How strong is the patent against prior art challenges?
While granted based on clear novelty and inventive step, the narrow claim scope makes it vulnerable if prior art can replicate the patented features.

5. What is the patent's expiration date?
Expected expiration in 2036, assuming all maintenance fees are paid timely and no invalidation actions are initiated.
