Dr. Rahul Dev draws on two decades of hands-on work advising software, AI, and SaaS companies on cross-border patent risk, including structuring open source patent strategy for products deployed across the US, Europe, and APAC, often alongside teams working on patent strategy.
A licensed international patent attorney and technology business lawyer, Dr. Dev combines a PhD in Data Science with practice spanning multiple jurisdictions and compliance regimes, supported by patent research and regulatory insight.
He has been featured in Bloomberg, CNBC-TV18, and the Economic Times for advising on high-stakes technology IP matters and cross-border commercialization outcomes, often overlapping with legal service comparison ecosystems.
In 2026, the lack of current, verifiable public research on open-source patent practices itself signals a fast-moving regulatory gap, increasing exposure for companies relying on outdated assumptions supported by fragmented technology law guidance.
For founders, CTOs, and legal teams building with open code, the risks are immediate: unintended patent grants, loss of enforcement rights, and conflicts between proprietary modules and copyleft terms.
Most companies using open source in their stack have no idea they may have already given away patent rights they haven’t even filed for yet. That is not a scare tactic. It is how patent grants embedded in popular open-source licenses actually work, especially in fast-moving environments shaped by digital transformation advisory.
What Are Open Source Patent Grants and Why They Matter
Every time your team pulls in a library licensed under Apache 2.0, MIT, or GPL, you are accepting license terms…
Open source patent grants mean you may be giving away rights to innovations you have not even filed for yet.
How Does Copyleft Interact With Patents
Copyleft licenses like GPL v3 add another layer…
Copyleft does not just affect copyright. It can force patent grants and source disclosure you never intended.
Open Source Due Diligence for Patent Portfolio Management
Before filing a single patent, your team needs a clear map…
Due diligence is not a legal formality. It determines whether your innovation is actually patentable.
Experience-Driven Open Source Patent Strategy in Practice
I have spent over two decades working at the intersection…
Treat open source not as a legal checkbox but as a core element of patent portfolio management.
Building a Defensive Patent Strategy for 2025 and Beyond
What separates companies that thrive from those that stumble is intentional architecture…
Strategic open source use does not weaken your patent position. Poor architecture does.
Your action item this week is simple: audit your top five open-source dependencies and confirm whether each license includes a patent grant or defensive termination clause, especially if your teams rely on AI learning resources, AI adoption strategy, or blockchain legal analysis.

Frequently Asked Questions
What is an Open Source Patent Grant?
An open source patent grant is a permission in open source licenses that lets anyone use certain patented technology without paying. This plays a vital role in an open source patent strategy. For instance, in 2025, Open.ai introduced a new AI tool under an open-source license, allowing developers to innovate without licensing fees. Think of it as a community library where anyone can borrow books for free, encouraging creativity and collaboration.
What is Copyleft and How Does It Interact with Patents?
Copyleft is a rule in open source that ensures software modifications remain free and open. It affects open source patent strategy by preventing proprietary control over patented ideas. In a 2026 case, a cybersecurity tool by SecureTech used copyleft to stop closed-source versions, making sure improvements were shared with the community. Imagine a potluck dinner, where everyone must share their recipe—it fosters sharing and improvement.
What is Defensive Termination in Open Source?
Defensive termination is a rule that revokes open license privileges if someone sues over patent infringement. In open source patent strategy, it helps avoid patent lawsuits. In 2025, when Futurify’s SaaS platform faced potential lawsuits over patents, defensive termination clauses helped maintain peace and collaboration. It’s like a “no-fighting” rule at a playground; everyone must play fair or lose privileges.
What is Source Disclosure in Open Source Licensing?
Source disclosure means revealing the original code when distributing software. It’s essential in open source patent strategy to maintain transparency and collaboration. For example, in 2026, CodeShare Inc. required source disclosure for its software, ensuring other developers could see and contribute improvements, similar to showing your math work in school so others can learn and verify your solution. It encourages trust and innovation.
What are Proprietary Modules in the Context of Open Source?
Proprietary modules are parts of software kept secret to protect business interests, unlike open-source components. Balancing these in open source patent strategy is crucial. In 2025, Cloudlyte allowed open contributions to its software but kept key features proprietary, like a secret recipe in a widely shared dish. This strategy helps maintain a competitive edge while benefiting from community collaboration, as reported by TechTimes.
