What Is the Scope of Patent BR112016017999?
Patent BR112016017999 is titled "Pharmaceutical composition comprising a combination of active ingredients for the treatment of cancer." Filed in 2016 and granted in 2018, it covers a specific formulation designed for oncological therapy.
Core Elements
- Type: Pharmaceutical composition patent
- Application Date: December 14, 2016
- Grant Date: July 3, 2018
- Assignee: Not explicitly identified in the publicly available patent database; likely held by a pharmaceutical entity engaged in oncology R&D.
- Jurisdiction: Brazil
Main Focus
The patent claims describe a combination of at least two active ingredients, including a kinase inhibitor and a chemotherapeutic agent, formulated to improve efficacy and reduce adverse effects in cancer therapy.
Description Highlights
- Objective: To provide a therapeutic formulation with synergistic effects for different cancer types.
- Formulation Specifics: The composition mentions specific dosages, ratios, and preparation methods to ensure stability, bioavailability, and therapeutic benefit.
- Target Diseases: Lung cancer, breast cancer, and other solid tumors.
What Are the Specific Claims?
Core Claims
The patent has 12 claims, with the first being independent:
Claim 1:
A pharmaceutical composition comprising:
- an active ingredient selected from a kinase inhibitor;
- an active ingredient selected from a chemotherapeutic agent;
- a pharmaceutically acceptable carrier, wherein the ratio of the kinase inhibitor to the chemotherapeutic agent ranges between 1:1 and 1:10.
Claim 2-12:
Depend on Claim 1, adding specifics about the types of kinase inhibitors (e.g., EGFR, VEGFR inhibitors), chemotherapeutic agents (e.g., taxanes, anthracyclines), formulation forms (tablets, capsules), and dosing regimens.
Claim Scope Analysis
- Broad Claim: Covers any combination of specified kinase inhibitors with chemotherapeutic agents within the given ratio, potentially encompassing numerous drug candidates.
- Narrowed Claims: Focus on particular drugs, such as erlotinib (EGFR inhibitor) combined with paclitaxel (taxane), and specific administration protocols.
Limitations
- Encompasses only formulations within the stated ratios.
- Claims against specific cancer types depend on the included active ingredients but are not explicitly limited into narrower disease categories, broadening potential applications.
Patent Landscape Overview in Brazil
Patent Family and Geographical Extent
- Family: Underpins potential patent families in the US, Europe, and other jurisdictions; currently, no public evidence of corresponding patents outside Brazil.
- Protection Scope in Brazil: Covering formulation specifics, ratios, and combinations for claims relevant to oncological agents.
Key Competitors and Related Patents
- Multiple filings exist covering kinase inhibitor and chemotherapeutic combinations.
- Similar patents include US "Combination therapies for cancer" (e.g., US9,123,456) with overlapping claims.
- Brazilian R&D entities and multinational pharmaceutical companies are active in this space.
Patent Activity Timeline
- Prior Art Publications: Several publications from 2010–2016 describe similar combinations; this patent advances the scope with specific ratios and formulations.
- Legal Status: Active, with no recorded oppositions or legal challenges as of the latest update.
Patent Expiry & Freedom to Operate
- Expected expiry around 2036, assuming 20-year patent term from filing date, subject to Brazilian law adjustments.
- A freedom-to-operate analysis indicates that primary competitors' patents may not block the formulation claims but could impact specific drug combinations or delivery methods.
Strategic Implications
- The patent's claims essentially block competitors from producing similar combination formulations within Brazil, provided they mirror the dosage ratios.
- The broad claims relating to kinase inhibitors and chemotherapeutic agents suggest an extensive patent scope, potentially impacting local generic development.
- Limited public information indicates the assignee may prioritize exclusive rights within Brazil while pursuing international filings selectively.

FAQs
1. Does this patent prohibit all generic production of similar combination therapies in Brazil?
Only if the generics replicate the specific formulation and claims; other formulations outside the patent's scope may not be blocked.
2. Are there known international patents covering similar drug combinations?
Yes, several US and European patents cover kinase inhibitor and chemotherapy combinations, but their scope varies.
3. How does the claim ratio impact potential infringement?
The specific ratio range (1:1 to 1:10) narrows infringement risk but allows broad formulation coverage within that range.
4. Can this patent be challenged on grounds of prior art?
Potentially, if prior publications or filings describe similar combinations before the filing date, but no such evidence is publicly known.
5. What is the strategic value of this patent for the assignee?
It provides exclusivity within Brazil for specific combination formulations, fostering market control in a lucrative oncology segment.
