Biggest Marketplaces to Buy and Sell Patents

A patent is a vital document that establishes ownership of an innovation. However, simply possessing a patent will not bring the inventor any money. You must sell the patent, license usage rights, or market the product yourself to earn from your invention. If your idea has become a viable product after months of fiddling and experimenting, and you have a patent for your innovation after a successful patent search and application process. So, what's next?

Option 1: Take the money and run!

When you sell a patent, you can expect a speedy return on your investment. Thousands of inventions are patented each year, yet only a small percentage of those earn significant revenues if any at all. Some languages have been around for so long that their patent has expired. You can at least get some money for your invention if you sell your patent outright. Although a quick, painless payment may sound appealing, selling the patent throws up the inventor's claim to future benefits from his or her invention. Furthermore, until the product has been on the market for a long period, the money obtained from selling a patent may be insignificant. A patent buyer is unlikely to invest a lot of money on an unproven invention that is unlikely to make a lot of money.

Option 2: License the usage rights

For most inventors, licensing the right to create, use, or sell their product is the most profitable option. You keep ownership of the invention as a patent holder, and you get paid royalties on future sales of the product. An exclusive license can be granted to a single company or a group of enterprises. If you license your idea through a well-known corporation that already has the trust of the public, you'll have a better chance of making a lot of money. In addition, the licensee is responsible for any product malfunctions. Licensing usage rights, like selling a patent, does not ensure financial success. Your royalty cheques will be cancelled if the product fails to sell in the marketplace. Royalty payments range from 5% to 20%, so the patent holder would have to sell a lot of merchandise to get a lot of money. Relationships with licensees might sour, resulting in additional legal expenditures and headaches. Research the possible licensee and contact inventors' organizations like the United Inventors Association before giving away licensing rights.

Option 3: Be an entrepreneur!

All proceeds will go to your bank account if you create and market your idea yourself. However, legal and accountancy fees, business startup charges, and headache treatment could eat into those profits. The majority of inventors are terrible businesspeople. It is probably advisable to sell your patent or lease usage rights unless your idea requires little start-up cash and you are well-versed in corporate bureaucracy. Maintain a professional demeanor in your marketing activities. To promote your invention, write official letters and attractive brochures. A prototype, or at the very least a good drawing of the product, is also beneficial.

From the year 2009, almost $25 Billion worth of deals and 195000 patent assets were involved in 8100 deals. This humongous amount of money involved in 8100 deals shows the role of marketplaces where one can buy/sell/license their inventions. Unlike older times, today’s marketplace is powered by technology. Orthodox methods such as the inclusion of Brokers and one-on-one meetings to buy/sell/license patents are converted into online web-based platforms.

With the increase in competition for providing a marketplace, hundreds of patent owners face a dilemma every time they want to sell their patents. They're undecided about whether or not being listed on the first marketplace they came across is the best option. Furthermore, it is aggravating to browse through the websites of each marketplace, weigh the benefits and drawbacks, and choose one where they may put their patents in the hopes of a quick sale.

The problem of monetizing a patent portfolio isn't the only one in the IP landscape. Whether it's expanding a domain's patent portfolio or acquiring patents for defensive purposes to operate freely, it's common knowledge that patents listed on marketplaces can be purchased for a lower price than reaching out to individual patent owners, who will inflate prices if they believe the buyer, is a large entity.
