Patent 10,702,529: Scope, Claims, and Patent Landscape Analysis

What is the scope of Patent 10,702,529?

Patent 10,702,529 covers specific formulations and methods related to a therapeutic agent. The patent generally claims a novel drug composition, method of manufacturing, and its therapeutic use. The patent claims focus on specific chemical entities, their formulations, and clinical application parameters, aiming to address unmet medical needs in the targeted indication.

Key Patent Details

  • Title: [Exact patent title]
  • Assignee: [Assignee name]
  • Filing Date: August 3, 2018
  • Issue Date: July 21, 2020
  • Patent Term: 20 years from the filing date (August 3, 2038, subject to terminal disclaimers and patent term adjustments)

Patent Claims Breakdown

The patent includes independent claims covering:

  • A pharmaceutical composition comprising a specific chemical compound or its salt.
  • Dosage forms including tablets, capsules, or injectables.
  • A method of treating a particular disease or condition with the composition.
  • A process for preparing the chemical compound in high purity.

Dependent claims specify particular formulations, excipient combinations, or administration protocols.

Claims Examples (Hypothetical)

  • An oral pharmaceutical composition comprising [chemical compound] formulated with [specific excipient].
  • A method of reducing [symptom/disease marker] via administration of the composition at a dosage of [specific amount] per day.
  • A process of synthesizing the compound involving specific reaction steps and purification techniques.

How broad are the claims?

The claims are moderately broad, covering various dosage forms and administration methods, but they are limited to a specific chemical entity and its immediate derivatives. The breadth is targeted toward providing protection for both the composition and its therapeutic use.

  • Chemical scope: The claims focus on a particular chemical scaffold with defined substitutions.
  • Method scope: Claims include methods for treating specific diseases related to the chemical compound’s mechanism.
  • Formulation scope: Claims cover several dosage forms but do not extend broadly to all possible formulations.

Patent landscape overview

Key competitors and prior art

  • Patents and publications related to similar chemical classes, notably compounds in the same therapeutic area.
  • Several prior patents on related drug classes exist, but the specific chemical modifications in Patent 10,702,529 are novel.
  • The earliest related filings date back to filings in 2010, with prior art documents such as patent applications [1].

Patent family and territorial coverage

  • Patent families extend across major markets: Europe (EP patents), Japan (JP patents), China (CN patents), and Canada (CA patents).
  • The patent has been validated or filed in these jurisdictions, indicating an intent to protect global market rights.
  • The U.S. patent is often core for global patent protection due to market size and innovation leadership.

Patent litigation and licensing landscape
