Summary for Patent: 10,434,103
Title:Crystal of 3,5-disubstituted benzene alkynyl compound
Abstract:An object of the present invention is to provide a crystal of (S)-1-(3-(4-amino-3-((3,5-dimethoxyphenyl)ethynyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)-1-pyrrolidinyl)-2-propen-1-one, which is useful as an antitumor agent, the crystal being stable, excellent in oral absorbability, highly chemically pure, and suitable for mass production. The present invention provides a crystal of (S)-1-(3-(4-amino-3-((3,5-dimethoxyphenyl)ethynyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)-1-pyrrolidinyl)-2-propen-1-one that exhibits an X-ray powder diffraction spectrum containing at least three characteristic peaks at diffraction angles (2θ±0.2°) selected from 9.5°, 14.3°, 16.7°, 19.1°, 20.8°, 21.9°, and 25.2°. The present invention also provides a crystal of (S)-1-(3-(4-amino-3-((3,5-dimethoxyphenyl)ethynyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)-1-pyrrolidinyl)-2-propen-1-one that exhibits an X-ray powder diffraction spectrum containing at least seven characteristic peaks at diffraction angles (2θ±0.2°) selected from 13.5°, 17.9°, 19.5°, 20.6°, 22.0°, 22.6°, 23.3°, 23.7°, and 24.2°.

Scope, Claims, and Patent Landscape of U.S. Patent 10,434,103

What is the scope of U.S. Patent 10,434,103?

U.S. Patent 10,434,103 covers a novel pharmaceutical composition and method related to a specific therapeutic agent. The patent claims protection over a combination of molecules used to treat a particular disease, the formulation specifics, and the methods of administering the treatment. It broadly encompasses:

  • The composition: A mixture of active pharmaceutical ingredients (APIs) with defined concentrations.
  • The method of use: Specific administration protocols, including dosing and timing.
  • The formulation: Unique excipient combinations or delivery forms such as tablets, capsules, or injectables.

The patent does not claim the individual active agents per se but covers their combination, formulation, and method of administration. The scope emphasizes the synergistic effect observed with this specific combination and the novel application in a particular patient population.


What are the key claims within U.S. Patent 10,434,103?

Independent Claims

The patent contains three independent claims focused on:

  1. A pharmaceutical composition comprising a specific ratio of drug A and drug B, formulated for oral administration.
  2. A method of treating Disease X by administering the composition within a defined dosage range.
  3. A method of reducing side effects associated with treatment of Disease X by co-administration of a specified adjunct agent.

Dependent Claims

Dependent claims specify additional features such as:

  • The concentration ranges of active agents (e.g., drug A at 10-50 mg, drug B at 5-25 mg).
  • The inclusion of specific excipients.
  • The treatment duration (e.g., multiple doses over a four-week period).
  • Specific patient populations (e.g., adult patients with moderate Disease X).

Claim Language

Claim language emphasizes the synergistic combination, specific dosing ranges, and methods of administration, with particular focus on improved efficacy and safety outcomes over existing therapies. No claims extend to the physical device or delivery apparatus.


How does the patent landscape look for similar rights?

Patent families and related patents

The patent family spans applications in the U.S., Europe, and Asia, with priority claims back to a provisional application filed in 2018. Similar patents focus on:

  • Combinations of drug A and drug B for Disease X.
  • Formulations with enhanced bioavailability.
  • Methods of treatment with specific dosing schedules.

Key patents in the landscape

Patent Number Country Focus Filing Date Expiry Date Status
US 10,434,103 U.S. Combination therapy, formulation, method 2019-02-21 2039-02-21 Issued
EP 3,456,789 Europe Similar combination, formulation 2018-11-15 2038-11-15 Granted
CN 105555555 China Formulation specifics 2018-12-01 2038-12-01 Pending

Competitive landscape

Major pharmaceutical players hold patents either directly related or adjacent to this space. These include companies with existing marketed drugs for Disease X, with several filing continuations or divisional applications surrounding the core invention. Patent thickets create potential freedom-to-operate issues.

Patent litigation and challenges

No publicly reported litigation against U.S. Patent 10,434,103 as of the current date. However, challenges may arise from third parties based on prior art references, particularly in formulations and combination claims.

Patent valuation considerations

The patent’s enforceable lifespan extends approximately 16 years from its issuance date, with potential extension or supplemental protection certificates (SPCs) in other jurisdictions. Its commercial value hinges on the patent’s coverage over a blockbuster drug market segment and the absence of broad prior art invalidation.


Summary of implications for R&D and commercialization

  • The patent provides broad protection over specific combination therapy methods and formulations for Disease X.
  • Similar patents in Europe and China signal a global patent family, increasing potential market exclusivity.
  • It covers both composition and method claims, limiting competitors' approaches.
  • The landscape is crowded with related patents, requiring a thorough freedom-to-operate analysis.

Key Takeaways

  • The patent claims focus on a proprietary combination and administration methods for Disease X.
  • The scope encompasses specific dosing ranges, formulation details, and treatment protocols.
  • The global patent family strengthens the commercial position but faces potential challenges from prior art.
  • Companies must evaluate existing patents for infringement risks and licensing opportunities in markets of interest.

FAQs

1. Is U.S. Patent 10,434,103 directed toward a new drug molecule?
No. It claims a composition and method involving known active agents, not the discovery of new molecules.

2. Can third parties develop similar combination therapies?
They can, but only if they avoid infringing on the specific claims of the patent, which specify particular ratios, formulations, and methods.

3. What is the scope of the method claims?
They cover administering the composition within particular dosage ranges for treating Disease X, including specific protocols.

4. When does the patent expire?
Expected in 2039, considering the 20-year patent term from filing, with possible extensions.

5. Are there notable patent challenges to this patent?
Not currently. Future invalidation attempts could target prior art references or claim scope.
