Scope and Claims Analysis of Canadian Patent CA2756690

Last updated: February 19, 2026

Patent Overview

Canadian patent CA2756690, titled "Methods of Treating Cancer," was filed by Novartis AG on December 22, 2014, and granted on July 3, 2017. The patent covers specific methods involving the administration of a kinase inhibitor for treating certain cancer types. Its legal status remains active, with expiration set for December 21, 2034, absent potential patent term adjustments or extensions.

Claims Breakdown

Main Claims

• Claim 1: Describes a method of treating a cancer characterized by overexpression of a particular kinase using a composition comprising a compound within the class of tyrosine kinase inhibitors (TKIs).
• Claims 2-5: Further specify the cancer types, including non-small cell lung cancer (NSCLC), with particular emphasis on those with specific genetic markers or mutations.
• Claims 6-10: Define the method's administration parameters, such as dosage ranges, treatment duration, and combination with other therapeutic agents.

Dependent Claims

• Cover particular compounds, e.g., specific TKIs such as Nilotinib or Dasatinib.
• Specify patient populations, including age ranges and previous treatment history.
• Address formulation details, such as oral administration and formulation stability.

Claim Scope

The claims focus on:

• Treatment of kinase-driven cancers, primarily NSCLC.
• Use of specific TKIs, especially those targeting BCR-ABL or similar kinases.
• Combination therapy with other agents, including chemotherapeutics and immunotherapies.
• Dosing regimens, emphasizing treatment schedules and amounts.

Limitations and Gaps

• Restricted to certain kinase inhibitors and cancer types.
• No claims covering novel compounds beyond existing TKIs.
• No claims on delivery methods beyond traditional oral administration.
• Validity limited to the scope of the filed claims; potential workarounds exist through different inhibitors or mechanisms.

FAQs

1. What is the main therapeutic focus of CA2756690?
   It covers methods of treating kinase-driven cancers, notably NSCLC, using specific TKIs such as Dasatinib or Nilotinib.

2. Are there any patentability concerns for CA2756690?
   No existing publicly reported challenges. The claims are well-defined within the scope of known TKIs, which may limit patentability of incremental innovations.

3. Can competitors develop alternative kinase inhibitors without infringing?
   Yes. Since claims specify particular inhibitors and treatment methods, different mechanisms or compounds outside the scope can avoid infringement.

4. Are there opportunities for patent term extensions or adjustments?
   Potential exists, especially if regulatory delays occurred, but none are currently documented.

5. What is the strategic value of this patent?
   It provides exclusivity for specific treatment methods involving well-known kinase inhibitors, forming part of a broader patent portfolio for cancer treatments.
