How to Patent an Idea and Sell It: A Simple Guide for Investors

So, you have discovered a great idea. It's the next Uber, the next Ring, or the next Post-it Note. But then what? Do you start a company? Do you fundraise? Or perhaps, just perhaps, you patent the idea and sell it? It's easy, isn't it? It is, provided you know what you are doing.

In this blog, we are going to answer your questions like “how to patent an idea and sell it?” or “how to sell an idea to a company?”, and the potential risks and benefits. So, if you’re wondering “how do I sell an idea to a company?”, you’re going to get your answer today.

Furthermore, we’ll talk about how investors like you can be an intelligent part of the process. Let's get into the details. 

10 Steps to Patent an Idea and Sell It

Step 1: Know What You Are Selling

Don't run off to the patent office yet, ask yourself this first: is this really an idea you can patent? The thing is, you can’t patent a broad concept. You need a specific invention. Something that does something. What that means is: 

• A machine or product
• A process or methodology
• A new chemical compound (a composition of matter)
• A design (for an appearance or quality of something)

That is, "I want a flying car" won't cut it, but "I have a wing-fold mechanism for city flying cars" could. Investors should ensure that the concept is well developed in order to be patentable. Otherwise, all your time and money will go in vain.

Step 2: Keep It Secret, Keep It Safe

Ideas are elusive. Discuss them too soon, and you stand in danger of losing your advantage.

Here's what you (or the business you are investing in) should do:

• Don't publish it online.
• Don't pitch without cover. 
• Use NDAs (Non-Disclosure Agreements) when you are speaking with partners or businesses. 

When inquiring how to sell an idea to a company, recall this: Nobody wishes to purchase an idea that they have the ability to steal. 

Step 3: Conduct a Patent Search

Before you file, make sure that the concept is not taken. This is a prior art search — a high-sounding phrase meaning, "Did someone else come along and invent this first?"

You may conduct a simple search on:

• The United States Patent and Trademark Office (USPTO) website
• Google Patents
• Or have a professional patent attorney do it

Why go through the motions? Because you can't patent your own version of something that is already patented by someone else. 

Step 4: File a Provisional Patent Application (PPA)

A Provisional Patent Application provides you with an immediate means of claiming your invention without going through all the formal hoops yet. Here are the benefits: 

• It is less expensive (approximately $75-$300).
• It's 12 months long.
• It entitles you to use the phrase “Patent Pending”.

It is ideal for inventors in their early stage or for investors. You are able to experiment in the market, fundraise, or locate buyers — all whilst your concept is being kept protected.

Be as specific as you can with your PPA. The more detailed your answer is, the stronger your eventual patent will be.

Step 5: File a Non-Provisional Patent Application

The temporary patent provides you with time, but ultimately, you'll have to obtain the genuine article — a Utility Patent or Design Patent.

This is the full application that:

• Undergoes examination by the USPTO.
• Can take 1–3 years to be approved.
• Can cost anywhere from $5,000 to $15,000 (and up). 

Yes, it is a serious investment. But if the concept has legs, it is well worth the money.

Here's how you can say it:

As an investor, this is where you need to do your due diligence. Are the market conditions ready? Are there any interested companies? Are there competitors hovering? Knowledge of this can determine if it is the time to go all-in.

Step 6: Prepare Your Pitch

Patent in pocket (or in process), here's the exciting part: selling the concept. Let's tackle the elephant in the room: how do I pitch an idea to a company?

Here's what you'll need:

• A clear, concise pitch that summarizes the problem, solution, and advantage.
• A basic FAQ page, or even a demo/proto. 
• A pitch deck or a one-pager.
• A solid grasp of the target company's business. 

Make it extremely easy for them to say yes. Don’t give them any chance to reject it. 

Step 7: Reach Out to the Right Companies

This is the point where you get strategic. You don't want to send out junk mail to random businesses. You want to identify those that:

• Function in the same domain.
• Have a proven record of acquiring IP.
• Need innovation quickly.
  
  

You can start with:

• Businesses with high R&D budgets.
• Named in startup acquisition reports.
• Companies that are expanding or growing product lines.

LinkedIn is your friend. Conferences, network meetings, and investor gatherings are too. Remember that when you are planning on how to pitch an idea to a company, relationships are everything. Having a warm introduction is invaluable.

Step 8: Licensing versus Selling

So, do you license the patent or do you sell it outright? Let’s talk about Licensing first.

A license allows you to grant a company the authority to use your patent in return for payments of royalties.

Benefits: 

• You still have the ownership.  
• You receive regular income.
• You can license it with numerous businesses.
  
  

Drawbacks: 

• Takes longer to scale.
• Requires contract management and payments.

Now, let’s talk about Selling. Selling involves you giving up the patent completely for a one-time payment.

Benefits: 

• Quick payment.
• No follow-up duties and responsibilities. 

Drawbacks: 

• You forfeit all future rights

As an investor, this choice hinges on your exit objectives. Desire speedy return on investment? Sell it. Desire long-tail revenue stream? License it.

Step 9: Negotiate Like a Pro

Congratulations if the company is interested. Now is the crucial part — the deal. 

Here are the areas of negotiation:

• Purchase price or rate of royalty
• Territory (wherein they can sell)
• Duration (how long it is usable)
• Exclusivity (can others license it as well?)

Call in a patent attorney or licensing specialist here. Don't attempt this yourself unless you've completed dozens of deals.

Step 10: Make It Official

Once both parties have agreed, get everything in writing. This includes:

• Assignment agreement (sales)
• License agreement (agreement for licensing)
• Any payment terms and milestones

And don't forget to update the USPTO in case you sell the patent. That keeps everything clean and legal.

Build a Business Around the Patent

Let’s say you’re not ready to sell the idea just yet. Or maybe the market isn’t ready. That’s okay — there’s another path: build a business around the patent.

This is a smart move, especially for investors who want to increase valuation before an exit. A patent isn’t just a legal document — it’s an asset. One that can support:

• Product development
• Fundraising
• Market exclusivity
• Competitive moat

In fact, startups with strong IP often attract serious investors. Why? Because they’re harder to copy, easier to defend, and more likely to negotiate better acquisition terms.

Here’s how you can leverage a patent:

1. Start a company around the IP
   Form an LLC or C-Corp and assign the patent to the company. This structure makes it easier to raise capital and negotiate deals.
   
   
2. Build a minimal viable product (MVP)
   Investors love traction. Even a basic prototype that proves demand can increase the value of your patent tenfold.
   
   
3. Use the patent to block competitors
   If the patent is strong, you can keep others from entering the space. That creates pricing power and leverage in partnerships.
   
   
4. License the tech while you build
   Want cash flow without losing control? Offer non-exclusive licenses to select companies while keeping long-term rights.
   
   

Bottom line: Owning a patent doesn’t mean you need to sell it right away. Sometimes, the best move is to use it as a launchpad. If you’re serious about angel investing, it pays to think beyond the obvious. Because the patent game isn’t just about protection, it’s about power.

‍Real-Life Examples to Encourage You 

Need evidence that this works? Check these out: 

Spanx: Sara Blakely patented her undergarment concept, then created a billion-dollar company. 

James Dyson: He submitted 5,127 designs before securing a patent for his vacuum, now valued in billions. 

Idea buyers such as Quirky and Edison Nation: They are in business solely for licensing and selling ideas.

And yes, businesses actually purchase ideas that are solutions for actual problems, particularly in consumer products, clean energy, health tech, and software.

Why Investors Should Care

So you might be asking yourself, all this is terrific for inventors, but what about investors?

Here’s why it matters:

• Low-risk, high-reward investments: Patents can be purchased during an early stage and resold for profit.
• Investments backed by IP: Patents create tangible, defendable value for start-ups.
• Strategic moves: Certain VCs create portfolios of patents for use in M&A transactions.

And,  there's an increasing trend of angel investors funding ideas rather than companies. If you have the appropriate legal structure, you can fund an idea, get it patented, and participate in the profits when it is sold.
