No Legal Requirement, One Very Real Deadline
Kickstarter and Indiegogo do not ask for patent numbers. Nothing stops you from launching with zero filings. But the day your campaign page goes live, you have made a public disclosure of your invention, and that event starts clocks you cannot stop.
In the United States you get a one-year grace period from your own disclosure to file. In Europe, China, Japan, and most of the rest of the world there is no grace period at all. Launch first and foreign patent rights are gone that day, permanently. If you ever intend to sell outside the US, or to license to a company that does, that is the whole decision right there. The mechanics and the exceptions are covered in public disclosure before filing a patent.
What Launching Actually Discloses
A campaign page is close to an ideal prior art reference. It has a dated publication, a detailed description written by the inventor, photographs and video of the working product from multiple angles, an explanation of how the mechanism works, specifications, and often an engineering update series that walks through internal design decisions. Campaign creators publish more technical detail than most patent specifications contain, because detail is what converts backers.
Everything on that page becomes prior art against your own later filing outside the grace period, and against you in Europe immediately. It is also a complete manufacturing brief for anyone who wants to copy you.
What Filing First Actually Buys
Four concrete things, and it is worth being precise because expectations here are usually inflated.
- Preserved foreign rights. The big one. A filing before launch keeps every international door open for the next 12 months.
- A priority date that beats fast followers. Under first-inventor-to-file, someone who sees your campaign, files their own application, and beats you to the office wins. A filing on record before launch removes that scenario.
- Patent pending status. It appears on the page, deters casual copying, and matters to some retail buyers and licensees. What it does and does not permit is set out in what patent pending means.
- Platform takedown leverage. Both major platforms and the marketplaces where clones surface have IP complaint procedures. A pending application is weaker than an issued patent here, but a registered design patent or trademark is often enough to pull a listing.
It does not buy you the ability to sue anyone. You cannot enforce a pending application. Damages for the pre-grant period are limited and require the published application to have claims substantially identical to the granted ones, plus actual notice to the infringer.
The Provisional Is the Right Instrument Here
A properly written provisional costs $2,000 to $5,000 with an attorney, or $130 to $320 in USPTO fees if you file it yourself, against $10,000 to $18,000 for a full non-provisional. On a campaign budget where the video alone runs $5,000 to $15,000 and total pre-launch spend commonly reaches $30,000 to $60,000, as broken down in how much a Kickstarter campaign costs, the provisional is not the line item that breaks you.
The trap is treating it as a placeholder. A provisional only gives priority to what it actually discloses. Three pages of marketing prose protects three pages of marketing prose. Write it as a complete specification: drawings, dimensions, materials, tolerances where they matter, alternate embodiments, and the variants you might ship later. Then, critically, do not let the campaign page disclose anything the provisional did not, because anything new in the campaign is unprotected and self-published. The standard is described in how to file a provisional patent application.
Timing: file at least two weeks before launch. The receipt takes days, and you want the confirmation in hand before the page goes live, not the morning of.
The Uncomfortable Truth About Copycats
Successful campaigns get cloned. Listings appear on marketplaces within 30 to 90 days of a viral campaign, often before backers receive their rewards, at a third of the price. This happens whether or not you have a patent, because the copies come from factories with tooling already running and no interest in whether a US application exists.
A patent does not prevent copying. It gives you a legal claim you then have to fund. What actually limits the damage in the first year is a combination of things:
Speed to fulfillment. Every week between funding and shipping is a week a cloner uses. Campaigns that ship in four months lose far less than campaigns that ship in eighteen.
Design registration. A design patent covering the product's appearance issues in roughly 12 to 18 months, costs $2,000 to $4,000, and is the single most effective tool for marketplace takedowns because infringement is visually obvious. For consumer products with distinctive form, file one alongside the utility application; the route is in how to file a design patent.
Brand. A registered trademark is cheap, enforceable, and stops sellers from using your name and your campaign photography, which is how most clone listings get traffic.
Manufacturing hygiene. If your own factory is the leak, no filing helps. The controls that matter are covered in will a Chinese factory copy my product.
A Pre-Launch Checklist
- Decide whether foreign markets are real. If yes, file before launch. Not negotiable.
- Run at least a serious self-search so you are not funding a product that infringes someone else, and so the campaign does not attract a cease and desist in week two.
- File a substantive provisional covering the shipping design and its plausible variants.
- File a design patent application if the appearance is distinctive.
- File a trademark application on the product name.
- Confirm every inventor and contractor has assigned rights to the company in writing.
- Check that the campaign page discloses nothing beyond what the provisional covers.
- Calendar the 12-month non-provisional deadline the day the provisional is filed.
The Decision Is About Your Market, Not About Fear
A US-only kitchen gadget with a six-month product life and no licensing ambition may genuinely not need a patent, and the money is better spent on tooling and fulfillment. A product with international distribution potential, a licensing endgame, or a defensible technical core should not launch unfiled. Either way it should be a decision you made deliberately rather than one the launch date made for you, and it fits inside the broader planning in crowdfunding a product launch.
