How to Know When You’re Ready to File a Nonprovisional Patent Application

If you have a provisional patent application pending on your invention, you have one year to assess the production / distribution / marketing costs versus the potential profitability of your idea, before filing a nonprovisional patent application. If that sounds like a pretty big to-do list to complete in a year, it definitely is.

Holding a provisional patent application pending, but failing to file a nonprovisional patent application by the one year deadline, means you lose the right to that filing date, and could potentially lose ownership rights to the invention. This outcome is fine if you have done your research and determined that the invention cannot support a viable business. It’s not fine if you haven’t completed all of your research prior to the deadline. Unfortunately extensions are not possible.

As you conduct research to determine the commercial viability of your invention, you will want to spend a lot of time qualifying the professionals you will be hiring to complete their role during this information-gathering phase. You want to utilize trusted resources, but don’t assume that everyone you meet is the right fit to assess your invention.

Keep in mind that every step of this process is meant to compile data to determine if you have a profitable business idea. That is the unanswered question you need to resolve before the one year deadline. Are there enough potential customers in the market, who are capable of paying the cost per piece to produce the product, as well as generate a profit for you, to make it worth your while to pursue this further?


To produce a prototype, you will need to hire a design engineer who is capable of bringing your invention to life. I strongly recommend that you put a written agreement in place stating that they will sign over any rights to their contributions to your invention, to avoid additional complications down the road. Additionally, you will investigate potential manufacturing facilities and evaluate the costs associated with each.

The next question at this phase is funding to commercialize your invention. Many inventors have chosen to go the crowdfunding route, but not many know that different sites have different policies about the types of inventions those sites will allow. Also this is definitely a place where the adage “it takes money to make money,” kicks in. If you’re asking potential donors to support your cause, you’ll need high quality, compelling video or photos, good copywriting to describe your invention, in addition to various donor incentives based on the level of their pledge. Crowdfunding can be highly effective and give you insight into what you hope to be the anticipated demand for the product.

Which raises the next point, what is the market demand for what you’re looking to produce, and how much are people willing to pay for it? A crowdfunding campaign can give you a much better sense of consumer interest and a potential price point, but keep in mind that it represents only a sliver of the population that has become interested in crowdfunding campaigns. If you end up manufacturing your product, where and how are you expecting it to be distributed? Is there a large enough demand to support long term production? Working with a market research company can give you additional insight into the long term potential.

If you’re looking to eventually make millions with your product, you should plan to spend hundreds of thousands on determining the product’s safety, marketing and product development over the same time period. As your product moves through each level of production—scaling up from 100 units to 10,000 units to 100,000 units, and so on, you’ll do additional product development to accommodate the scale of production. And out of that additional product development will come additional opportunities for patents.

Once you have done this research and are satisfied that this product is in demand in the market, and the price minus production costs will yield a healthy profit for you, you are ready to file a nonprovisional patent application. But the work doesn’t stop there. In eighteen short months you need to decide what foreign countries you want to file in, and preparing for that will be the subject of our next article.

    Inventor0875: You’ve anticipated our next article brilliantly. We will be discussing PCTs there. But to your point, yes, if you want more time to decide on which countries to file in, you need to file a PCT before your US provisional expires.

    “In sixteen short months you need to decide what foreign countries you want to file in”.

    Including that phase, may confuse many people.

    As you did not mentioned filing PCT within 1 year from PPA.

    That’s right. Several of my clients file updated provisionals on a regular basis for just the reason you mention. If they are not ready at the anniversary of the first provisional, at least they can get the date of the second (or third, etc.)

    Good point. IBM used to regularly publish ideas they didn’t want to patent in “The IBM Technical Disclosure Bulletin”. It was effective. I actually had one of those publications cited against an invention of my own when I was in corporate R&D.

    It is in situations like this, where you continue to develop, refine, and better understand what the invention is and can be, that I find it can benefit to continually update, revise, and refile the provisional application. The filing fees for a provisional application are small (currently $260 for a large entity). When filing a non-provisional, you can then claim priority back to every provisional application within the 1 year window. For instance, if you update and refile every 2 months and then file a non-provisional at 14 months, you have only lost 2 months of priority as opposed to losing all priority if you had only filed a single provisional application. The additional cost for this benefit — 6 provisional filing fees — currently $1,560 for a large entity or $780 for a small entity.

    One more point – if you file a provisional application and later decide not to file a non-provisional, your provisional application will not be published and cannot serve as prior art against anyone else attempting to patent the same invention. So if you have given up on the dream of gaining exclusive rights to your idea, at least you can publish it openly elsewhere (trade journals, etc…) rather than hiding it or watching someone else pick the fruit. Unless, that is, you prefer to develop the product and maintain trade secret.
