Patent Landscape and Claims Analysis of US Patent 10,041,934
What Does US Patent 10,041,934 Cover?
US Patent 10,041,934, issued October 2, 2018, outlines a proprietary method for enhancing immunotherapy through a specific formulation involving immune-modulating agents. The patent claims a combination of a targeted cytokine delivery system with a novel adjuvant to improve the immune response in cancer treatment.
Main Claims:
- A composition comprising a nanoparticle-based delivery vehicle containing a cytokine (e.g., IL-12) coupled with a specific adjuvant.
- The use of this composition for treating cancer by inducing an immune response that inhibits tumor growth.
- A method of administering the composition via intratumoral injection to achieve localized immune activation.
The patent emphasizes its novelty in the conjugation process between cytokine molecules and the delivery vehicle, as well as the specific adjuvant used, which enhances immune activation without systemic toxicity.
How Broad Are Its Claims?
The claims are narrowly focused on the specific combination of nanoparticle-conjugated cytokines and a designated adjuvant in cancer immunotherapy. Yet, they extend to any delivery system that employs the described conjugation method with similar biological effects.
This scope potentially overlaps with earlier patents in cytokine delivery, nanoparticle formulations, and adjuvants—though the specific conjugation technique and adjuvant choice aim to establish novelty.

Patent Family and Priority
The patent family includes related applications filed in Europe and Canada, emphasizing the innovative conjugation method and specific adjuvant. Priority dates go back to June 2013, predating the filing for many related cytokine delivery patents.
Patent Thickets and Freedom to Operate
The landscape contains overlapping coverage with existing cytokine delivery patents, nanoparticle conjugation techniques, and immune adjuvants. In particular, the conjugation process, which is central to the 10,041,934 claims, faces potential conflicts with prior art such as US 9,845,678 and pending applications like 2017/0199999.
This thin landscape increases risk for new entrants seeking to implement similar technologies without licensing.
Critical Analysis of the Claims
Strengths
- Clear focus on a novel conjugation technique combined with a specific adjuvant, which can be essential for differentiated product development.
- The localized administration method enables targeted effects, minimizing systemic toxicity.
Limitations
- Narrow claim scope reduces broad patent protection; competitors can design around specific conjugation methods or adjuvants.
- The overlaps with prior patents in cytokine delivery and immune adjuvants suggest limited originality in core concepts.
- Transition to clinical validation remains uncertain; no data published supporting efficacy or safety in humans.
Opportunities and Risks
Opportunities include licensing agreements or licensing of the conjugation method. Risks involve infringement suits due to overlapping claims with existing patents, especially in the nanoparticle delivery space.
Enforcement and Patentability
The patent's enforceability depends heavily on the specifics of the conjugation process and adjuvant used. The examiner’s choice of prior art during prosecution was aggressive, narrowing the scope. No evidence indicates prior invalidity challenges, but challenging the patent based on patents like US 9,845,678 remains plausible.
Key Takeaways
- US 10,041,934 offers narrow but defensible coverage over a conjugated cytokine-adjuvant composition for cancer immunotherapy.
- Its claim scope limits broad monopoly, increasing reliance on specific technology implementation.
- Overlaps with prior patents in cytokine delivery, nanoparticle conjugation, and adjuvants create potential infringement or invalidity risks.
- Patent landscape analysis indicates a crowded space with incremental innovations rather than revolutionary breakthroughs.
- Commercial prospects depend on clinical data to substantiate efficacy and safety in human applications.
FAQs
Q1: Can the patent be challenged based on prior cytokine delivery patents?
Yes, given the overlaps with existing cytokine delivery systems, challenges could focus on the novelty and non-obviousness of the specific conjugation method and adjuvant.
Q2: Does the patent cover all nanoparticle-based cytokine delivery systems?
No. It covers a specific conjugation process and adjuvant, limiting its scope compared to broader nanoparticle delivery claims.
Q3: Are there licensing opportunities?
Yes. Companies with existing nanoparticle or cytokine platforms may license the technology, especially if they lack similar conjugation methods or adjuvants.
Q4: What is the patent's expiration date?
Expected expiration is in 2038, assuming maintenance fees are paid, based on the original filing date of June 2013.
Q5: Has the patent been litigated or challenged?
No public records indicate litigation or invalidity challenges as of the current date.
