The Strangest Patents Ever Granted

The strangest patents ever granted show that an invention does not need to sound sensible to qualify. In Nepal, the Department of Industry (DoI) assesses patent applications under the Patent, Design and Trademark Act 1965 (PDTA), followed by publication, a 35-day opposition period, registration and a seven-year term.

Key Takeaways

Weird patents can be real legal rights, not just internet jokes. The DoI registers patents in Nepal under the PDTA, tests whether an invention is new and useful, publishes accepted applications, allows 35 days for opposition, and grants protection for seven years, renewable twice.

• A strange idea is not automatically unpatentable; the technical solution and disclosure matter.
• Many viral “funny patents” are applications, expired rights, or foreign grants rather than current Nepali patents.
• A patent protects how a product or process works, not simply its amusing name, packaging, or appearance.
• Nepal uses direct national patent filing at the Department of Industry because it is not part of the PCT.
• Patent publication in Nepal gives interested people a 35-day period to object before registration.
• A Nepal patent lasts seven years and can be renewed twice, subject to the applicable requirements.
• Before disclosing an unusual invention, get practical advice on novelty, documentation, and filing strategy.

What makes a patent one of the strangest patents ever?

Strange patents granted usually protect an idea that sounds comic, awkward, or unnecessary at first hearing. Yet a patent office does not judge taste. The DoI and other patent authorities ask whether the claimed invention meets the legal test and is properly described, while Nepal’s PDTA gives registered patents a seven-year term.

The joke often comes from a short title rather than the underlying engineering. A rotating ice-cream cone may sound ridiculous, for example, but it involves a mechanism intended to turn the food. A laser-based cat exercise method sounds playful, but a patent document can still set out a defined method and claimed use.

That distinction matters. A patent is not a prize for having an odd thought. It is a limited legal right over a stated technical invention. The document must explain enough for the invention to be understood and must define the legal boundary through claims.

Which bizarre inventions were actually granted patents?

Several famous weird patents were granted in the United States, including a cat-exercise method and an anti-eating mask. Those grants are foreign records, not Nepal rights. The Department of Industry would separately assess any direct Nepal application under the PDTA and publish an accepted application before registration.

These examples should be read carefully. A patent number shows that a patent was granted in a named jurisdiction at some point. It does not automatically show that the patent remains in force, that every feature was protected, or that the product became commercially successful.

Does a strange patent grant prove that an invention is useful?

A patent grant shows that an authority accepted the application under its own law and procedure; it does not prove market success. In Nepal, the DoI examines whether an invention is new and useful, then allows a 35-day opposition period after publication before issuing a registration certificate.

“Useful” should not be confused with popular. A novelty gift, pet accessory, festival gadget, or unusual kitchen tool may solve a narrow problem for a small group of buyers. Commercial value depends on manufacturing, safety, pricing, distribution, and whether people actually want it.

In practice, patent protection can still matter for an odd product. A founder may need it to show that a mechanism has been documented, to deter direct copying, or to support a discussion with a manufacturer. None of that replaces product testing.

Can you patent a weird invention in Nepal?

You can apply for patent registration in Nepal even if your invention sounds strange, provided it is a genuine technical invention. The Department of Industry examines the application under the PDTA, and a successful patent is registered for seven years, with renewal available twice for further seven-year terms.

Start with the technical problem. “A funny umbrella for dogs” is not a patent claim. A new folding joint that keeps a pet umbrella stable in wind may be an invention if it is genuinely new and adequately described. The focus is on the working feature, not the marketing line.

Do not disclose the mechanism casually before considering a filing. Nepal follows a national, first-to-file system for industrial property registration in practice. Early records, drawings, and careful filing preparation can be vital where two people develop similar solutions.

For a deeper explanation of the threshold, read our guide to what can be patented in Nepal. It is sensible to have a patent professional assess the technical material before you present the idea publicly.

How do you register an unusual patent in Nepal?

You register an unusual patent by filing a complete application with the DoI, responding to examination, and passing publication without a valid objection within 35 days. The Patent, Design and Trademark Act 1965 governs this national process, which ends with registration and a patent certificate.

1. Describe the invention clearly. Record the problem, the working mechanism, the materials or steps, and the result. Keep dated development notes and drawings.
2. Check what already exists. Search similar products, technical publications, and earlier patent documents. A novelty review should cover the mechanism, not merely the product name.
3. Prepare the patent specification and claims. The specification explains the invention. Claims define the precise protection sought. Drawings can be essential where words cannot fully explain the construction.
4. File with the Department of Industry. Submit the prescribed application and supporting documents. The filing establishes the formal Nepal application.
5. Address DoI examination. The DoI reviews whether the invention is new and useful. Clear claims and a practical disclosure reduce avoidable questions.
6. Wait through publication and opposition. An accepted patent is published for public information. An interested person may object within 35 days.
7. Complete registration. If no valid objection prevents registration, the DoI registers the patent and issues the certificate.

Which documents does the DoI need for a strange patent application?

The DoI generally requires a patent application form, a notarised power of attorney, and the invention’s specification and claims. Priority or foreign-patent documents may also be needed for an overseas applicant. These documents support DoI examination and the later 35-day publication stage under the PDTA.

• Patent application form: the formal request for registration.
• Notarised power of attorney: authority for the representative handling the application.
• Specification: the written technical explanation of what the invention is and how it works.
• Claims: the statements that define the protected scope if the patent is granted.
• Drawings or diagrams where needed: visual material that helps explain parts, movement, or technical relationships.
• Priority documents where relevant: certified or notarised foreign filing records where a priority claim is being made.
• Foreign registration evidence where relevant: certified or notarised documents for a foreign patent.

A common mistake is submitting a product pitch instead of a technical disclosure. A colourful sketch and a slogan may help sell a novelty product, but they do not replace a full explanation of the invention’s working features.

How long does a Nepal patent last after registration?

A Nepal patent lasts seven years from registration and may be renewed twice for further seven-year terms, creating a maximum potential term of 21 years. Before registration, an accepted application is published and remains open to opposition for 35 days through the Department of Industry process.

Patent renewal is not automatic. Keep the registration certificate, ownership details, and renewal calendar in order. If you are unsure whether a technical feature, product appearance, or brand name needs protection, the answer may involve more than one IP right.

Should a bizarre invention use a patent, design, or trademark?

A bizarre product may need a patent for its technical function, industrial design registration for its appearance, and trademark registration for the name used in trade. The DoI administers all three under Nepal’s industrial-property framework, although their terms and legal tests differ.

Imagine a hand-cranked momo warmer shaped like a tiny Kathmandu bus. The heat-retaining mechanism may be a patent issue. Its distinctive outer shape may be an industrial design issue. “Momo Motion” and its logo are brand assets that may need trade mark registration.

Do not assume one filing covers everything. A patent does not reserve a catchy product name, and a trademark does not stop a competitor from copying an unprotected mechanism. Our guide on industrial design versus patent protection explains the practical split.

What mistakes do people make with funny patents?

People often mistake a published application for a granted patent, or a foreign grant for enforceable rights in Nepal. The DoI registers Nepal patents under the PDTA, while publication here gives interested parties 35 days to oppose before a certificate is issued.

• Believing every viral image: check the patent number, jurisdiction, grant status, and current legal status before repeating the claim.
• Confusing an idea with an invention: an amusing concept needs a defined, working technical solution.
• Publishing before filing: product videos, crowdfunding pages, and trade-show demonstrations can create serious novelty risks.
• Writing vague claims: claims that are too broad or unclear can weaken the application and create examination problems.
• Ignoring foreign limits: a United States or European patent does not automatically protect an invention in Nepal.
• Forgetting the brand: protect the product’s name and logo separately where appropriate.

Can a foreign owner protect a strange patent in Nepal?

A foreign owner can seek direct patent registration in Nepal through a Nepal-based representative because Nepal is not part of the Patent Cooperation Treaty system. The Department of Industry examines the national application, publishes accepted patents, and permits opposition for 35 days before registration.

A foreign patent is useful background, but it does not automatically create a Nepal patent. Where available, a Paris Convention priority claim can be relevant, so do not leave Nepal planning until after a launch date. The World Intellectual Property Organization explains the wider international IP framework, but national rights still depend on the Nepal filing route.

For the local legal framework, consult the Nepal Law Commission’s legal resources and obtain advice on your specific facts. If your invention will be sold abroad as well, review our guidance on international patent filing from Nepal.

In short

The strangest patents ever granted are a useful reminder that patent law protects technical solutions, not good taste. In Nepal, the Department of Industry applies the PDTA process to ordinary and unusual inventions alike: application, examination, publication, 35-day opposition, registration certificate, and a renewable seven-year patent term.

If your unusual product has a real working feature, treat it seriously. Document it, avoid premature disclosure, assess prior art, and decide whether patent, industrial design, trademark, or a combination gives the right protection.
