Scope of the Patent
Technological Field
The patent concentrates on methods for administering therapeutic agents capable of treating particular medical conditions—most notably, targeting [specific disease or condition] through optimized delivery techniques. It encompasses methods that improve upon existing protocols by enhancing bioavailability, reducing side effects, or enabling targeted delivery.
Innovative Focus
The innovation pivots on the administration regimen, involving specific dosages, routes, or formulations. The patent may cover novel dosing schedules, combination therapies, or delivery vectors—such as nanoparticles, liposomal formulations, or biodegradable implants.
Claims Scope
The claims of the patent are the legal core, delineating the boundaries of protection.
Claims Analysis
Independent Claims
The patent likely comprises multiple independent claims, which define the broadest scope of the patent:
-
Claim 1: Usually, a method claim covering a particular administration technique, for example, injecting a specified dose of a therapeutic agent via a chosen route within a defined time frame.
-
Claim 2: Might encompass specific formulations or delivery systems used in conjunction with the method.
The language often employs terms like "comprising," which is open-ended, allowing for additional elements, and specifically "administering," "treating," or "delivering."
Dependent Claims
Dependent claims narrow the scope, typically adding limitations or specific embodiments, such as:
- Use of particular dosages.
- Administration under certain physiological conditions.
- Using specific pharmaceutical carriers.
These claims create a fallback position in case broader claims are invalidated.
Interpretation of Claims
The claims' wording explicitly sets the scope:
-
Broad Claim Coverage: If broad claims exist, they may cover general methods for administering the therapeutic agent.
-
Narrower Claims: Focused on particular applications, formulations, or delivery vectors.
-
Prior Art Considerations: The scope must be balanced with existing art; overbroad claims could be challenged for encompassing known methods, whereas narrowly drafted claims might be easier to invalidate but offer limited protection.
Patent Landscape Positioning
Patent Family and Related Patents
Patent 9,522,155 likely belongs to a family of patents, including family members abroad or in subsequent filings, such as continuations, divisionals, or provisional applications. These related patents can extend protections geographically or creatively.
