Protect Intellectual Property Before Patenting - But How?

How to Protect Your Invention Before Filing a Patent

You can't fully "protect" an invention before you file a patent, because patent rights come from filing, not from having the idea. What you can do is avoid wrecking your chances, control who learns about it, and keep good evidence of what you had and when. That means keeping the invention confidential, using NDAs sensibly, documenting your work as you go, and filing early (often a provisional application) once it matters.

The rest of this article walks through each of those, and where a blockchain timestamp helps and where it doesn't.

The real risk before filing: losing novelty

To get a patent, an invention generally has to be new. Anything that makes it available to the public before you file can count against you. That includes a conference talk, a blog post, a crowdfunding page, a public demo, a product sold or offered for sale, or a paper posted online.

How strict this is depends heavily on where you file.

In the United States, there is a one-year grace period for certain disclosures made by the inventor, counted back from the filing date (see 35 U.S.C. 102(b)(1) and the USPTO's guidance). Plenty of other countries are much stricter. The European Patent Convention, for example, has only narrow exceptions, so a public disclosure before filing can be fatal to a European patent. Some jurisdictions fall somewhere in between.

If there's any chance you'll want protection outside one country, treat any public disclosure before filing as a mistake until a patent attorney tells you otherwise. And since this varies by country and changes over time, check current rules for the jurisdictions you care about.

Step 1: Keep the invention confidential

The simplest protection is not telling anyone who doesn't need to know. Be deliberate about who sees what.

Share the minimum needed. A manufacturer quoting a part may not need to understand how the whole system works. An investor deciding whether to take a meeting rarely needs the enabling details of the invention.

Be careful with casual channels. Posts, demos at meetups, shared repositories set to public, and recorded videos are all common ways people disclose by accident.

Step 2: Use NDAs, but know their limits

A non-disclosure agreement gives you a contractual remedy if someone leaks what you shared. It also helps show the disclosure was confidential rather than public, which matters for novelty.

Some practical points. Get it signed before the conversation, not after. Define what counts as confidential. Be specific about what the other party may and may not do with the information. And accept that many investors won't sign NDAs at early stages, so you may need to decide how much to share without one.

An NDA is a legal tool for after something goes wrong. It doesn't stop a leak, and it doesn't give you any patent rights. Use a lawyer for anything important, since enforceability varies by jurisdiction.

Step 3: Document your work as you go

Good records won't create a patent, but they help in several real situations: showing the development history of an invention, supporting a claim that you had something at a given time, responding to a dispute over who developed what, and supporting a defence in some jurisdictions that recognise prior use.

A few habits do most of the work:

* Keep dated notes, sketches, design files, code commits, test results and photos in one place.

* Write down what changed and why, not just the final result.

* Record who contributed what, when more than one person is involved.

* Keep originals and versions rather than overwriting them.

Paper and digital records are only as persuasive as they are hard to dispute. A notebook entry or file date can be questioned, since file metadata can be edited and a private folder is just your own claim. That's the gap a timestamp is meant to fill.

Step 4: Add an independent timestamp to your records

A blockchain timestamp creates an independently verifiable record that a particular file existed in a particular form at or before a particular time.

With Certelo, the process works like this. You select a file, and your browser calculates its SHA-256 hash locally. A hash is a fixed-length fingerprint of the file's exact contents. Change one character and the fingerprint changes completely. That hash, not the file, is anchored to the Electra Protocol blockchain. Later, anyone holding the original file can recalculate the hash and check it against the blockchain record.

This has a property that matters here: the original file doesn't need to be uploaded to Certelo to create the record, and the hash can't be turned back into the file. So the act of timestamping doesn't disclose your invention to Certelo or to the public. You can build a dated record of your development without creating the kind of disclosure that threatens novelty.

Some sensible things to timestamp: design documents, lab notebook exports, source code snapshots, test data, prototype photos, and your draft patent specification. Timestamp versions as they change, so you end up with a sequence rather than one data point.

What a timestamp does not do?

This part matters, so I'll be blunt about it.

A timestamp does not create a patent or any patent right. It doesn't establish a patent priority date. In first-to-file systems such as the US (since 2013) and most of the world, your filing date is what counts, not the date you had the idea.

It doesn't prove you invented anything. It shows a file with a given hash existed by a given time. It doesn't say who made it, whether it was original, or whether someone else had it first.

It doesn't make the invention secret or stop anyone else from independently arriving at it, and it doesn't replace legal advice. How much weight a court or patent office gives any timestamp depends on jurisdiction and context, and I wouldn't promise a particular outcome.

What it does give you is one piece of supporting evidence: a date-bound record you didn't have to rely on your own say-so for.

Step 5: Consider a provisional application

Where it's available, a provisional patent application is the usual way to lock in an early filing date cheaply. In the US, a provisional lets you claim its date for a later non-provisional filed within 12 months. Whether it's useful depends on how well the provisional describes the invention, because a thin one may not support your later claims. Other countries have their own early-filing routes, and the Paris Convention priority period generally gives 12 months to file abroad after a first filing.

If you're close to a public launch, a funding round, or a trade show, this is usually the step to talk to a patent attorney about first.

Step 6: Decide whether you actually want a patent

Not everything should be patented. A patent requires publishing the invention, usually around 18 months after the earliest filing date. If you'd rather not reveal how something works, such as a process or formula that's hard to reverse-engineer, a trade secret may suit you better. Trade secret protection depends on taking reasonable steps to keep the information secret, and it gives you no protection against independent discovery or reverse engineering. Relevant frameworks include the EU Trade Secrets Directive (2016/943) and, in the US, the Defend Trade Secrets Act.

A third option is defensive publication: deliberately publishing the invention so it becomes prior art and nobody else can patent it. Here a timestamp is genuinely useful, since hashing the published document gives you a verifiable record of when it existed in that form.

A simple order of operations

If you're pre-filing and want a sensible default, it looks something like this. Keep the invention confidential. Document it as you develop it. Timestamp key versions as you go. Use NDAs where you have to share. Talk to a patent attorney before any public disclosure, and file a provisional before you go public if protection abroad matters to you.

Frequently Asked Questions

Can I protect an idea before I file a patent?

Not with a patent. Ideas alone generally aren't patentable, and patent rights begin on filing. You can protect confidentiality through NDAs and careful sharing, and keep evidence of development through records.

Does showing my invention to investors ruin my chances?

It can, depending on how it's shared and where you file. A confidential conversation under an NDA is different from a public pitch. In strict jurisdictions, public disclosure before filing can prevent patenting, so ask a patent attorney before you present.

What is a patent grace period?

It's a window during which certain disclosures by the inventor don't count against novelty. The US has one of 12 months. Many other jurisdictions have none or only narrow exceptions, so don't rely on it if you want international protection.

Can a blockchain timestamp give me a patent priority date?

No. Priority dates come from patent filings. A timestamp can support your records of development, but it isn't a substitute for filing.

Does Certelo see my files?

No. The SHA-256 hash is calculated locally on your device, and the original file isn't uploaded just to create the record. Only the hash is anchored to the blockchain.

Can someone else see my invention from the hash?

No. A hash can't realistically be reversed to recover the file. That said, if someone already has the exact file, they can compute the same hash and confirm a match.

What if I change the file after timestamping it?

The new version will produce a different hash, so it won't match the earlier record. That's the point: the record covers the exact file you timestamped. Timestamp new versions as they matter.

Is a timestamp admissible in court?

It depends on the jurisdiction and the circumstances, and I can't give you a general answer. It's best understood as supporting evidence, not a guaranteed outcome. A lawyer can tell you how it might be treated where you are.
