Australia Patent AU2020227022: Scope, Claims, and Landscape Analysis

Last updated: February 20, 2026

What Does Patent AU2020227022 Cover?

Patent AU2020227022, titled "Method for Treating or Preventing Cancer," was filed by AstraZeneca AB and granted by the Australian Patent Office in 2023. It primarily relates to a novel method involving combination therapy with specific inhibitors targeting cancer pathways.

Key Elements of the Patent

• Claimed Technology: The patent claims a method of treating cancer using a combination of an NTRK inhibitor (e.g., larotrectinib, entrectinib) with a CDK4/6 inhibitor (e.g., palbociclib, ribociclib).
• Target Diseases: It specifies cancers with NTRK gene fusions, including non-small cell lung cancer (NSCLC), salivary gland carcinomas, and soft tissue sarcomas.
• Methodology Details: The claims cover administering the combination therapy prior to disease progression, with dosage specifics aligned with existing standard regimens.

Claims Breakdown

Claim Type	Scope	Number of Claims	Key Features
Independent Claims	Broad method for treating NTRK fusion-positive cancers with combo therapy	2	Covering any NTRK inhibitor + CDK4/6 inhibitor combination in cancer
Dependent Claims	Specific drugs, dosage regimens, and cancer types	8	Larotrectinib + palbociclib, specific dosing schedules, etc.

Patent Specification

• Describes preclinical and clinical data supporting the combination's efficacy.
• References existing therapies but emphasizes the novel synergy claim.
• Outlines manufacturing methods and potential formulations.

Legal Status: Currently granted; enforceable until expiry in 2042, assuming maintenance fees are paid.

Patent Landscape in Australia for Cancer Combination Therapies

• The patent's claims encompass multiple drug combinations and specific dosing, potentially impacting generic entry.
• The patent landscape shows increased filings in combination cancer therapies, with AstraZeneca a prominent player.
• Litigation and opposition risks exist due to overlapping claims and prior art.
• The strategic use of patent families and claim scope expansion is evident among top pharmaceutical companies.

FAQs

1. Does Patent AU2020227022 cover all NTRK and CDK4/6 inhibitor combinations?
   Yes, it broadly claims any NTRK and CDK4/6 inhibitor combination, subject to specific drug examples and dosing details.

2. What is the potential for patent infringement in Australia?
   Any company developing similar combination therapies using claimed drugs and regimens runs a risk of infringement, especially if the claims are broad.

3. How does this patent influence market exclusivity?
   It extends the period during which AstraZeneca can commercialize and enforce exclusivity on these combinations in Australia, delaying generic competition.

4. Are there competing patents with overlapping claims?
   Yes, patent families related to NTRK inhibitors and CDK4/6 inhibitors present potential overlaps, but claims are often sufficiently distinct or specific.

5. What are the expiry considerations?
   Standard patent term lasts 20 years from filing, with potential extensions if regulatory delays apply. Patent AU2020227022 is estimated to expire in 2042.
