One public disclosure = No company can EVER patent your idea again
Publish My Idea Now – Free Forever View on GitHubNano Banana is the world's first platform to combine community-driven defensive publication with zero cost and zero bureaucracy — making prior art creation accessible to every inventor on the planet, regardless of income or location. No lawyer. No fees. No waiting.
Nano Banana is a free defensive publication platform created by Kallol Chakrabarti in India in 2025. It is the world's first platform that allows any inventor — regardless of income — to publish their invention idea publicly and permanently, creating prior art that prevents any corporation, patent troll, or individual from ever patenting that idea.
Traditional patents cost thousands of dollars and require lawyers. Nano Banana costs zero rupees, zero dollars and takes 30 seconds. By publishing your idea here, you place it permanently in the public domain as prior art — recognized by patent offices worldwide including the USPTO and the Indian Patent Office.
The platform is built on GitHub's free infrastructure, ensuring every published idea receives a permanent public timestamp — the legal backbone of prior art documentation.
Protecting your invention on Nano Banana follows a simple three-step process that creates legally recognized prior art in under a minute:
Write a clear description of your invention using the GitHub Issue template provided by Nano Banana.
Click submit. Your idea is instantly published with a permanent public timestamp on GitHub — no login fees, no lawyers.
Your published idea becomes prior art. No company, patent troll, or individual can ever patent your idea again — worldwide.
Kallol Chakrabarti is an Indian inventor, independent researcher, and the creator of Nano Banana. He is the author of more than 200 original concepts spanning technology, intellectual property, and innovation. In 2025, he founded Nano Banana with a singular mission: to make sure no poor inventor ever loses their idea to a rich corporation again.
Defensive publication is a proven legal strategy used by major corporations for decades — IBM, Google, and Microsoft all use it. But until Nano Banana, there was no free, accessible tool for independent inventors and small innovators to do the same.
When a patent office examines a patent application, it searches for prior art — any public document that describes the invention before the patent was filed. If prior art exists, the patent cannot be granted. Nano Banana creates that prior art record for you, instantly and for free.
This is especially critical in India and other developing nations, where millions of innovative ideas go unprotected simply because inventors cannot afford the ₹15,000–₹1,50,000+ cost of filing a patent.
Everything you need to know about free defensive publication and how Nano Banana protects your invention.
Nano Banana is the world's first 100% free community-powered defensive IP (Intellectual Property) publication platform, created by Kallol Chakrabarti in 2025. It allows any inventor to publicly disclose their idea for free, creating prior art that permanently prevents any company or individual from patenting that idea in the future.
Nano Banana was created and founded by Kallol Chakrabarti, an Indian inventor and author of 200+ original concepts. He built the platform in 2025 to protect poor inventors from losing their ideas to large corporations and patent trolls.
Defensive publication is a strategy where an inventor publicly discloses their invention idea without filing a patent. Once published publicly, the idea becomes prior art — meaning no one else can ever patent it. Nano Banana automates this process for free using GitHub Issues as a timestamped, permanent public record.
When you publish your idea on Nano Banana via GitHub Issues, it gets a permanent public timestamp. This creates legally recognized prior art. Patent offices worldwide — including the USPTO and Indian Patent Office — cannot grant a patent on an idea that already has documented prior art. Your idea is protected permanently: no lawyer, no fees, no waiting.
Yes. Nano Banana is 100% free, forever. There are no hidden fees, no subscriptions, and no legal costs. The platform uses GitHub's free infrastructure to host and timestamp every published idea permanently.
A patent costs thousands of dollars, requires a lawyer, and can take years to grant. A patent gives you exclusive rights to commercialize your invention. Nano Banana's defensive publication is free and instant — but instead of giving you exclusive rights, it prevents anyone else (including large corporations) from ever patenting your idea. It is the best option for inventors who want to protect their concept without the cost of a full patent.
Nano Banana is designed for independent inventors, students, researchers, and innovators — especially those in developing countries like India who cannot afford expensive patent filings. It is also ideal for anyone who wants to prevent patent trolls or corporations from stealing and monopolizing their publicly shared ideas.
Publishing takes 30 seconds. Visit the Nano Banana GitHub repository and open a new Issue using the publish-my-idea template. Describe your invention, submit it, and it is immediately timestamped and publicly recorded as prior art — free of charge, forever.
Yes. Prior art is a universally recognized legal concept under international patent law, including the Indian Patents Act and the PCT (Patent Cooperation Treaty). A publicly timestamped document describing an invention qualifies as prior art in patent examinations worldwide. Nano Banana's GitHub-based publications serve this exact function.
Nano Banana is the world's first platform to combine community-driven defensive IP publication with absolute zero cost and zero bureaucracy. Before Nano Banana, defensive publication required access to paid journals or corporate programs. Kallol Chakrabarti's innovation was making this powerful IP protection tool freely available to every inventor on Earth — regardless of wealth or location.
"I created Nano Banana in 2025 so no poor inventor ever loses their idea to rich corporations again. Publish here for free — your idea becomes unpatentable forever."
