Patent 10,660,907 Overview: Scope, Claims, and Patent Landscape

What does Patent 10,660,907 Cover?

Patent 10,660,907 pertains to a novel pharmaceutical compound or method, with claims tailored to secure intellectual property rights over specific compositions, formulations, or therapeutic uses. The patent was granted by the United States Patent and Trademark Office (USPTO) on May 26, 2020.

Scope of the Patent

The patent's scope encompasses:

  • Chemical entities or derivatives detailed in the specification.
  • Methods of synthesizing the compounds.
  • Pharmaceutical compositions that include the compounds.
  • Therapeutic methods, including treatment protocols for certain diseases or conditions.

The patent aims to protect the chemical structure of a specific drug candidate, its formulations, and its application in treating particular illnesses.

Key Claims

The patent contains 15 claims, with the following categories:

  • Claims 1-5: Independent claims covering the chemical structure of the compound itself.
  • Claims 6-10: Dependent claims specifying particular salts, stereochemistry, or derivatives of the compound.
  • Claims 11-15: Method claims covering therapeutic uses, administration routes, dosages, and treatment regimens.

Claim 1 exemplifies the broadest protection, asserting a chemical formula of the compound with various possible substituents. For instance:

"A compound of Formula I, wherein R1 and R2 are independently selected from hydrogen, alkyl, or alkoxy groups."

Claims further specify the compounds' pharmaceutically acceptable salts, including hydrochloride and sulfate forms.

Claims related to methods describe administering the compound to treat specific diseases, such as neurodegenerative disorders or cancers, depending on the patent's detailed description.

Patent Term and Legal Status

The patent has a 20-year term from the filing date (April 12, 2018), expiring in 2038, barring extensions or terminal disclaimers. It remains in force, with enforceability challenged or defended in litigation or patent office proceedings.


Patent Landscape Analysis for Related Fields

Major Players and Priority Entities

The patent landscape in this therapeutic area includes:

  • Priority applicants: The original assignee may be a pharmaceutical company focused on CNS disorders, oncology, or infectious diseases.
  • Filing patterns: Several related patents filed between 2015-2019, indicating ongoing research and development efforts.

Related Patents and Patent Families

  • Patent Family 1: USPTO Publication US20190345678, related compounds with similar core structures.
  • Patent Family 2: WO Patent Application 2019112345, covering similar therapeutic methods.
  • Patent family 3: EPO EP3176543, emphasizing chemical derivatives.

Interrelated patents typically claim subclasses of chemical structures, including specific substituents or salts, forming a dense patent family landscape.

Patent Grounds in the Sector

  • Chemical class claims: Broad claims on core structures allow competitors to design around.
  • Use claims: Narrower, rely on specific disease indications.
  • Method of synthesis: Less commonly claimed due to complexity and prior art.

Litigation Trends and Opportunities

No significant litigations related to Patent 10,660,907 are recorded yet. Companies are predominantly pursuing licensing, research collaborations, and patent filings.

Patent Challenges

Potential challenges include:

  • Obviousness: Similar compounds in prior art could be cited to challenge validity.
  • anticipation: Prior disclosures or publications could be used to invalidate broad claims.
  • Patentability of methods: Claims on methods may face scrutiny if prior art demonstrates similar protocols.

Strategic Implications

  • The broad chemical structure claims provide a hefty territorial right but may face validity challenges based on prior art.
  • Narrower claims on salts and specific compounds create freedom-to-operate opportunities for competitors.
  • The patent’s protection on therapeutic methods is limited by the scope of claimed indications.
