Do you need a prototype in order to register a patent? A patent gives the patent owner exclusive rights to make, sell, or license the invention defined in it. Do You Need a Prototype to Patent a New Invention? Many inventors wonder if they need a working prototype before patenting an invention. The simple answer is “no.” A prototype is not a part of the legal requirements prior to filing a patent application with the U.S. Patent and Trademark Office (USPTO). While prototypes can be valuable in developing your invention, they can also be costly. Developing a costly prototype is not required and in some situations may actually not be feasible. If a prototype of a new product can be constructed without spending a lot of money, then prototyping your invention can be a very good first step in the invention process.

Balancing the Benefits and Costs of Prototyping To determine if creating a prototype of your invention is a good idea, you need to consider both the costs and benefits. If the costs are too great, then you should consider an alternative path. Below are the benefits and costs of prototyping: Benefits of Prototyping Work out any potential design problems: Prototyping allows you to identify and solve design issues early in the product development process. Identify alternative solutions: Creating a prototype can reveal alternative ways to achieve your invention’s goals. Marketing tool: A prototype can be useful in marketing the invention to third parties, such as investors or potential licensees. Costs of Prototyping Unnecessary expense: If you are only licensing your patent rights, the expense of prototyping may not be justified. Delays the invention process: Prototyping can add significant time to the development process. Time and energy: Developing a prototype requires time and energy that might not be necessary for the patent process. When You Should Prototype Your Invention There are situations when you should consider prototyping your invention before filing a patent application: Affordable and quick development: If a prototype will cost less than $1,000 and can be developed quickly, it might be worth the investment. Illustrating basic functions: If a prototype is needed to demonstrate the basic functions of your invention, it can be helpful. Uncertainty about design: If you are unsure if your product design will work, a prototype can provide valuable insights. When You Should Not Prototype Your Invention There are also situations when you should consider not prototyping your invention before filing a patent application: Simple design and no manufacturing intent: If you do not intend to manufacture and the product design is simple, a prototype may not be necessary. High prototype development costs: If developing a prototype would be expensive and you do not intend to manufacture, it may not be worth the cost. Licensing only: If you intend to only license your patent rights and the technology does not require a prototype to be understood, skipping the prototype is advisable. Prior public disclosure: If you have a prior public disclosure of your invention, you need to file a patent application before the one-year anniversary of your first public disclosure in the United States. Prohibitive costs: If the expense of creating a prototype would prevent you from pursuing your invention further, it is better to focus on the patent application first. Prototyping vs. Not Prototyping Ultimately, deciding whether to prototype your invention comes down to weighing the time and money required. Some inventors believe that prototyping is a crucial first step, while others view it as an unnecessary expense if you intend to license your patent rights. Balancing the benefits and costs of prototyping your idea is essential before hiring a prototype developer. A prototype is not required to obtain a U.S. patent. However, assuming the prototype is kept confidential and there is no offer for sale, sale, public use, or other problematic activity before filing a complete and timely patent application, it may be helpful for various reasons to prepare a prototype. Generally, an inventor has a one-year grace period from their first disclosure to file a U.S. patent application, but many foreign countries do not provide any grace period, so keeping an invention and prototype confidential prior to filing is important to preserve any possible patent rights. A prototype can help a registered patent attorney or patent agent better understand your invention and prepare a more robust patent application. It can also aid in preparing both a design patent application (for appearance) and a utility patent application (for function). For design patents, in particular, having an actual prototype can help ensure accurate and compliant drawings. A prototype can help with a patent search in giving as much detail as possible to your patent professionals.. If you can describe your invention in sufficient detail for someone skilled in the field to practice it without a prototype, you should consider filing a patent application as soon as possible. This can secure your priority date and protect your invention against prior filings by others. Further Considerations Patent Specification Requirements: Every patent application must include a specification that explains the invention in sufficient detail for someone skilled in the field to practice it. Controller’s Requests: In some cases, the patent office may request a model or sample illustrating the invention. This would only be required before the patent is granted, giving you time to create such a model or sample after filing the application. First to File: Most patent systems, including the United States and India, operate on a ‘first to file’ basis rather than ‘first to invent,’ emphasizing the importance of filing as soon as possible. This means choosing between a provisional application and non-provisional patent applications. In conclusion, while prototyping can be beneficial, it is not mandatory for filing a patent application. Inventors should carefully consider their specific circumstances and the costs and benefits involved before deciding whether to develop a prototype.

Now, let’s get to the meat of this. Do I need a model or prototype before I can file a patent? No. It’s one of the most misunderstood aspects of patent law: you do not need a model or a prototype to file for a patent application. Instead, you only need to have enough information in order to be able to explain your invention to someone, such as a manufacturer, that is capable of making it. As a rule of thumb, if you’re able to explain how to make your invention or how your invention works, then you should be able to file for a patent application. But – that’s one of the tricky parts here let’s get to from something to say theoretical to, well, what happens in real life. If somebody comes to our practice and says, “I have a great invention! It’s a transporter beam!” and you’re not really able to describe how you’re going to take molecules of people, turn them into, you know, some other matter. And then, you know, deposit the person safely on the other side. Well, it’s not really going to work all that well, but again, that goes back to the practical part of this. You have to be able to describe the invention, make sure your invention is new, novel, make sure it’s not obvious, absolutely. Make sure that you’re able to describe it so that those who have the capability to make it can make it. You don’t need a model. You don’t need a prototype, but you have to have the ability to describe it fully. Without that description, your patent application will just never be able to go to fruition.

(Plaintiff-Appellant) vs. Hologic, Inc. and Cytyc Surgical Products, LLC (Defendants-Appellees) Court: United States Court of Appeals for the Federal Circuit Decision Date: August 11, 2020 Here is a case all about showing a prototype in public and the drawbacks of doing so if the product is not ready to go through the patenting process. The case of Minerva Surgical, Inc. v. Hologic, Inc. et al. involved Minerva’s patent for a gynecologic device used in “endometrial ablation.” The United States Court of Appeals for the Federal Circuit affirmed a lower court’s ruling that invalidated Minerva’s patent based on the public use bar. Minerva had displayed a prototype of its device at an industry expo more than one year before filing the patent. The court found that this display constituted a public use of the invention, which can invalidate a patent under the pre-America Invents Act (AIA) version of the patent statute if the invention is in public use more than one year before the patent application date. Minerva argued that the display at the expo did not qualify as a public use for several reasons, including that it merely displayed the device, there was no disclosure of the invention because the device lacked a key claim limitation, and the invention was not ready for patenting as Minerva was still improving the technology at the time. The Federal Circuit rejected these arguments, noting that the expo was a si
