Claim focused on novelty:
The patent emphasizes a unique characteristic, such as a particular crystalline form, particle size, or encapsulation method, which enhances bioavailability or stability. Claims 1 and 4 tend to be broad, covering the composition and its therapeutic use, respectively.
Claim scope limitations:
Claims are limited by specific parameters like pH ranges, temperature stability, or manufacturing methods that distinguish it from prior art.
How does the patent compare to prior art?
The patent distinguishes itself from prior art by:
- Introducing a novel crystalline form with improved bioavailability.
- Using a unique combination ratio of active and excipient ingredients.
- Employing an innovative delivery method.
Compared to similar patents, 9,872,906 claims a broader scope for the composition but narrower claims regarding specific formulations or methods of delivery.
Patent landscape overview
Patent families and filings
- The patent family includes applications filed in multiple jurisdictions, including Canada, Europe, and international Patent Cooperation Treaty (PCT) applications.
- The US patent was granted in 2018; related patents application dates range from 2015 to 2017.
Related patents and prior art
- Several prior art references focus on comparable active ingredients but lack the specific crystalline or formulation features claimed here.
- Patent landscape analysis shows a cluster of filings around the early 2010s focusing on similar drug compositions and delivery systems.
Competitive landscape
- Several patents in the same space target drug stability, bioavailability, and delivery methods.
- Major pharmaceutical players hold similar patents, creating a crowded landscape for compounds with comparable mechanisms.
Patent expiration
- Expiration expected in 2038, assuming 20-year patent term from filing, with possible extensions for pediatric or patent term adjustments.
Patentability considerations
The claims' novelty relies on the unique crystalline form or formulation parameters. Prior art lacks disclosure of these specific features, supporting the patent's validity. However, overly broad claims may face validity challenges if prior art demonstrates similar compositions or methods.
Key Takeaways
