What is a Patent?

When we talk about a patent, this is a form of a license that gives the owner of the intellectual property, exclusive legal rights to exclude any other party from executing, selling or using an invention.

The license is given for a particular period under the condition that it will be published to enable public disclosure of such an invention.

Since, in many countries, intellectual property rights fall under civil law, the patent holder has the right to sue anyone who infringes the patent.

This means that principally, the patent holder reserves the right to protect the patented invention from commercially exploited by other parties.

So, which are these marketplaces or companies that sell patents?

The site also allows for the listing of patent applications, utility models, designs, as well as trademarks. Through the site, the patent owner gets a chance to list their patents while the companies that want to buy patents, gets to see the available patents in the market.

With their newly relaunched website, IP Marketplace provides extensive filtering that enables the users to easily find patents, as well as any other form IP.

A user can identify an IP from a specific technology category specified in which country its valid and offered under certain terms of a specific corporation agreement.

However, just like many other websites, this one also has one drawback. That is, the various categories are sometimes poorly selected or inappropriately named. For example, instead of the site listing the main technology groups as categories to allow users to choose from there, their categories are limited to few clusters.

These include the following:

  1. Food Tech,
  2. Biotech,
  3. Information Technology (IT),
  4. Art & Crafts,
  5. Machines,
  6. Pharma,
  7. and a variety of others.

One major advantage of the site is that it has an IP-evaluating tool. This helps patent owners to determine the value of their IP (Patent, Design, or Trademark).

How Much Do Patents Sell For?

Numerous inventors and patent owners have greatly profited from the proceeds they get patent sales. But, exactly how much does a patent cost? Well, based on the type of technology and invention, among other factors, the price of a patent might vary significantly.

According to research, if an investor owns a patent for an article and sells it through one retail store at minimum, there is a high possibility of corporate interest.

In most cases, vendors will report new products that they see when they visit a retail store, which in turn will amount to corporate interest.

In the event that an offer is made by the corporation, the patent can sell anywhere between $50k to $8 million or even higher.

However, an inventor who tries to market a patented idea to corporations can get anything between $5,000 and $35,000. Also, if a company intends to use your patent to produce products, it may opt to license your patent instead of buying it.

Through this option, you might get a royalty rate of about $2 million guaranteed per year plus a bonus that depends on sales.

Royalty agreement can usually run for two years but can sometimes be longer.
