Individuals or businesses buy patents to increase their standing in the patent market. It gives them the right to sole ownership to license or manufacture their inventions. Creating and implementing a patent buying program can improve the success of your company. 

Pros of Patent Buying

  • There has been an increase in patent buying in recent years, which means there is a thriving market available to individuals and businesses. 
  • Recognizing the fact that there are billions of dollars in patents available can help you realize the importance of management and the temptation to overbuy. 
  • Setting limits on buying patents while tracking potential patent purchases can help reduce spending, which results in a better chance of succeeding.
  • The patent holder has the option of selling his patent outright to another buyer. 
  • An inventor has the option of offering limited licenses via a contract with other buyers. 
  • Patents are considered a business asset.
  • Licensing allows the buyer to manufacture an owner's invention. The owner will receive either a royalty from sales or be paid in a lump sum. 
  • Inventors may be more motivated to license their patents to sell, use, or manufacture their products because this can be more profitable over time.

Cons of Patent Buying

  • Getting a patent does not mean you have it for an indefinite period to make it succeed. There is a limited timeframe to turn the exclusive rights into a profit before the patent expires. 
  • If multiple inventors file for a patent together, each can do as he pleases when it comes to manufacturing the invention or selling or licensing the patent to someone else. He does not need permission from the other inventors who filed with him. 
  • Before agreeing to a licensing arrangement, do thorough research of the interested party. Also, contact the United Inventors Association for information and resources.
