Patent Landscape and Claims Analysis of US Patent 10,046,031
US Patent 10,046,031, titled "Methods for treating cancer," was granted on August 14, 2018. The patent addresses a method involving the administration of specific compounds for cancer therapy, emphasizing selective targeting and enhanced efficacy. The landscape surrounding this patent includes a focus on immuno-oncology, kinase inhibitors, and targeted therapies.
What Are the Core Claims of US Patent 10,046,031?
Main patent claims focus on:
- The administration of a certain compound, notably a specific chemical structure, or pharmaceutical composition
- The treatment of cancer, especially solid tumors
- The use of a particular dosage regimen or administration route to improve therapeutic outcomes
Key claims specify:
- The compound's chemical identity: An inhibitor targeting a kinase or signaling pathway relevant to tumor growth (e.g., a specific small molecule with defined chemical features)
- Therapeutic methods involving the combination of this compound with immune checkpoint inhibitors
- Methods applied to patients with particular types of cancer (e.g., non-small cell lung cancer, melanoma)
Note: The patent’s claims are broad in terms of both chemical scope and application across multiple cancer types, but they depend on the specific structures and administration methods disclosed.

Related patent families include:
- Kinase inhibition methods
- Immunotherapies combining immune checkpoint inhibitors
- Targeted delivery systems
The landscape is highly fragmented, with overlapping claims on kinase inhibitors, immune modulation, and combination therapies.
Legal environment:
- Patent expiration dates vary, with many key patents expiring between 2019–2025
- Ongoing patent filings attempt to carve out specific chemical modifications and combination protocols
- Litigation and patent challenges focus on freedom to operate in the kinase inhibitor and immunotherapy segments
Critical Analysis of the Claims’ Breadth and Specificity
Strengths:
- Broad chemical scope allows coverage of multiple compounds fitting the disclosed structure
- Encompasses combination therapy with immune checkpoint inhibitors, a significant therapeutic trend
- Defines specific dosage and administration routes, providing operational clarity
Weaknesses:
- Claim breadth could be vulnerable to invalidation against prior art, notably prior kinase inhibitors and immunotherapy combinations
- Lack of disclosure on particular compounds’ efficacy data limits enforceability
- The dependence on combination strategies may be challenged if similar combinations are patented or disclosed earlier
Potential for patent infringement and litigation:
- Competing patents on kinase inhibitors and immunotherapies pose risks
- The use of similar chemical scaffolds or combination regimens may lead to infringement claims
- Patent challengers could argue obviousness due to the well-mapped landscape of kinase and immune checkpoint therapies
Novelty and inventive step considerations:
- The integration of disclosed compounds with immune checkpoint therapy might be inventive if supported by non-obvious synergistic efficacy
- The scope of claims concerning specific chemical modifications must be scrutinized for prior art overlap
- Patent office history indicates strict examination standards for chemical and combination claims
Strategic Implications
- Companies specializing in kinase inhibitors should assess patent risks before developing similar compounds
- Innovators in immunotherapy combinations need to navigate existing patents focusing on therapy protocols
- Patent holders may seek licensing or assert claims against competitors working on related treatments
Key Takeaways
- US Patent 10,046,031 covers targeted compounds and combination therapies for cancer treatment.
- The patent's broad chemical and application claims are designed to capture a significant segment of targeted and immuno-oncology therapies.
- The patent landscape is crowded, with overlapping claims on kinase inhibitors and immunotherapy combinations.
- Validity and enforceability depend on prior art, claim specificity, and supporting data.
- Legal and patent strategies should include detailed freedom-to-operate analyses considering existing patents in kinase and immunotherapy segments.
FAQs
1. Can this patent block competing kinase inhibitors?
Only if the compounds or methods infringe the specific claims; broad chemical claims may pose a risk, but validity challenges are likely.
2. How does this patent influence the development of combination cancer therapies?
It encourages further innovation but also increases potential patent infringement risks when combining different agents.
3. Are the patent claims limited to specific cancer types?
No, the claims are applicable across multiple solid tumors, increasing their scope.
4. What strategies can companies use to circumvent this patent?
Designing structurally distinct compounds or alternative dosing methods not covered by the claims.
5. How long is the patent protection?
Expire in 2038, assuming basic patent term adjustments.
