I Have an Invention — What Do I Do First?

You have an idea. Maybe it came in the shower, or while fixing something that should not have been broken, or while watching someone struggle with a tool that was obviously designed wrong. The idea feels real. It feels valuable. And now you are standing at a crossroads with no map.

This is the article you need right now — before you Google "how to patent," before you call a lawyer, before you tell your colleague, before you post anything online. The first 48 hours after conceiving an invention are the most consequential of the entire journey, because the mistakes made in those hours — usually from excitement and ignorance, not from carelessness — can permanently destroy your ability to protect what you have created.

Here is exactly what to do, in order, starting now.

Hour 1: Stop Talking

The single most important thing you can do in the first hour is nothing visible. Do not:

• Tell your coworker
• Call your friend who "knows about patents"
• Post about it on social media — not even vaguely
• Email a manufacturer asking "can you make this?"
• Describe it in a WhatsApp group
• Upload a sketch to any public platform

Every one of these actions is a public disclosure. In most of the world — including Europe and China — any public disclosure of your invention before you file a patent application destroys your right to patent it. There is no undo button. The GCC, Japan, South Korea, and some other jurisdictions offer grace periods of varying scope, but they are narrower than the US equivalent and should never be relied upon as a strategy. One Instagram post, one email to the wrong person, one excited conversation at a dinner party, and your patent rights in key markets are gone permanently.

The United States offers a 12-month grace period for the inventor's own disclosures. Australia, Canada, and South Korea have similar grace periods. But relying on a grace period as a strategy is like relying on your car's airbag instead of your brakes. It exists for accidents, not for planning.

The rule: tell no one until you have filed something. If you absolutely must discuss the idea with someone before filing — a trusted advisor, a potential co-inventor — get a signed Non-Disclosure Agreement first. See: NDAs for Inventors

Hours 1–24: Write Everything Down

While the idea is fresh and vivid in your mind, document it in writing. This is not a patent application — it is your inventor's record. It serves three purposes: it forces you to clarify your thinking, it creates a dated record of conception, and it becomes the foundation for everything that follows (prior art search, patent drafting, prototype specification).

What to Write

Open a document — digital or physical — and answer these questions:

What problem does this solve? Describe the problem in practical terms. Not "it improves fluid dynamics" — rather, "current garden hose nozzles leak at the connection point because the seal degrades after 6 months of UV exposure, requiring replacement. My invention solves this by..."

How does it solve it? Describe the mechanism, process, or structure that makes your invention work. Be specific about what is new — not just what your invention does, but how it does it differently from existing solutions.

What are the key components or steps? List every element. Number them. Sketch them. If it is a device, describe each part and how they connect. If it is a process, describe each step in sequence. If it is a material or composition, describe the ingredients and their proportions.

What alternatives could work? This is the step most inventors skip — and it is one of the most important. If the seal in your invention is made of silicone, could it also be made of EPDM rubber? Fluoroelastomer? PTFE? If the mechanism uses a spring, could it also use a magnet? A pneumatic actuator? Every alternative you document now expands the scope of protection you can claim later. See: How to Write a Patent Specification

What makes this different from what already exists? Describe every existing solution you are aware of, and explain specifically how yours differs. This is your initial prior art awareness — it will be expanded through formal searching, but your own knowledge of the field is the starting point.

How to Date and Preserve the Record

Digital: Create the document in a platform that timestamps automatically (Google Docs, Notion, email to yourself). Save a PDF copy with the date visible.

Physical notebook: Write in ink, date every page, and have a trusted witness (not a co-inventor) sign and date at least the first and last pages with the notation "Read and understood by me on [date]."

Why this matters: While most countries now use a first-to-file system (the filing date matters, not the conception date), a dated record of conception remains useful for derivation proceedings (proving someone stole your idea), for trade secret documentation, and for establishing your timeline if inventorship is ever disputed.

Days 1–7: Search Before You Spend

Before investing any money — on a patent attorney, on a prototype, on a provisional application — spend 4–8 hours searching for prior art. The goal is not to conduct a professional-quality search (that comes later). The goal is to answer one question: has someone already done this?

The Quick Search

Google Patents (patents.google.com): Enter a natural-language description of your invention. Read the top 20 results — not just the titles, but the abstracts and independent claims. Are any of them your invention?

Regular Google: Search for your invention as a product. "Self-sealing garden hose connector" — does it already exist as a product, even if not patented?

Amazon / Alibaba: Search for your invention as something you can buy. Many inventions that feel novel have already been manufactured and sold — particularly in China — without patent protection.

YouTube: Search for demonstrations of your invention concept. YouTube videos count as prior art.

What You Find Changes What You Do

Your exact invention already exists (patented or as a product): Stop. You cannot patent what is already known. Assess whether your specific implementation differs in a meaningful, patentable way — or redirect your effort.

Similar inventions exist but yours is clearly different: Good. Document the differences specifically. These differences become the focus of your patent claims.

Nothing similar exists: Either your invention is genuinely novel (proceed) or your search was not thorough enough (search more, using classification codes — see Patent Classifications Explained).

Days 7–14: Decide Whether to Proceed

Not every invention should be patented. Before committing money, answer five questions honestly:

1. Is it new? Based on your initial search, does your invention appear to be novel? If the prior art is very close, a patent may be obtainable but narrow — and narrow patents are expensive to prosecute and difficult to enforce.

2. Is there a market? Who would buy this, licence it, or pay to avoid it? A patent on an invention nobody wants is an expensive piece of paper. Identify at least three potential customers or licensees before investing in patent prosecution.

3. Can you afford the full journey? A provisional application costs $2,000–$5,000. A full US patent through grant costs $15,000–$25,000. Adding Europe and China adds $30,000–$60,000. Maintenance fees over 20 years add more. Can you fund this — or attract funding? If not, a trade secret strategy may be more appropriate. See: Do I Even Need a Patent?

4. Can infringement be detected? If your invention is a hidden internal mechanism that cannot be detected by examining the finished product, enforcement is practically impossible regardless of how strong your patent is. A patent you cannot enforce has limited value.

5. Is patent protection the right tool? For some inventions, trade secret protection (keeping the invention confidential forever) is more effective than patent protection (disclosing the invention in exchange for 20 years of exclusivity). See: Patent vs. Trade Secret

If the answer to questions 1, 2, and 3 is yes, proceed. If any answer is no, reassess before spending money.

Days 14–30: File Something

If you have decided to proceed, your priority in the first month is to file a patent application — even a provisional one — to secure your priority date. In a first-to-file world, the date you file determines your rights. Every day you delay is a day a competitor could file first or a day you might accidentally disclose.

The Provisional Patent Application (US, Australia, India)

The fastest and cheapest way to secure a filing date. A provisional application:

• Establishes your priority date
• Gives you "patent pending" status for 12 months
• Is never examined and never becomes a patent on its own
• Costs $160–$320 in US government fees (micro/small entity)
• Must be converted to a non-provisional within 12 months or it expires

What a good provisional contains: A complete written description of the invention — every embodiment, every variation, every alternative you documented in your inventor's record. Drawings. Draft claims (optional but recommended). The provisional should be as thorough as possible, because only what is adequately described in the provisional gets the benefit of its priority date.

What a bad provisional contains: A few paragraphs and a napkin sketch. This creates a false sense of security — you have a filing date, but if the provisional does not adequately describe the invention, your non-provisional claims will not get the benefit of that date.

Direct Filing (Jurisdictions Without Provisionals)

Japan, China, South Korea, Germany, and most GCC countries do not have formal provisional applications. In these jurisdictions, you file a full application directly, or you file a US/Australian provisional and use it as a Paris Convention priority document when filing in these countries within 12 months.

The 12-Month Clock

The moment you file your provisional (or first national application), a 12-month clock starts. Within those 12 months, you must:

• File a non-provisional application in your home country (claiming priority from the provisional)
• File a PCT application (if you want international protection)
• File directly in any country that matters to you (under the Paris Convention)

If you miss the 12-month window, you lose priority — and any public disclosure that happened after your provisional but before your non-provisional may destroy your rights. See: The Deadlines That Can Kill Your Patent

The First-Month Checklist

Everything before the attorney consultation costs nothing. The first real expenditure is the provisional filing — approximately $2,000–$5,000 with attorney assistance. From that point, you have 12 months to build your prototype, test the market, and decide how much further to invest.

What Happens Next

After the first month, the journey unfolds across months and years. The iInvent Encyclopedia covers every stage:

• Months 1–12: Build prototype → refine design → conduct professional prior art search → prepare non-provisional or PCT application. See: [How to Prototype Your Invention →] and [How to File a Patent Internationally →]
• Months 12–36: Prosecution — Office Actions, examiner interviews, claim amendments. See: [How to Respond to a Patent Office Action →]
• Months 24–48: Grant → licensing → enforcement → commercialisation. See: [You Got a Patent — Now What? →]

The full journey is covered in 60+ articles and 8 downloadable templates across this encyclopedia. But it all starts with what you do in the first 48 hours — and now you know what that is.
