Patent Mining

1. Reasons for patent mining

Patents rarely lead to monopolies

This is a misconception of most people. For example, if you invent a microphone and own the patent right, and someone else copies the microphone product, can you succeed in suing for patent infringement? The result is uncertain. The battery of microphone may be someone else’s patent. If you produce microphone, it could also be a tort.

Patents do not necessarily provide effective protection. This issue closely related to the timing, type, region, mix and field of application. For example, product life is only 2 to 3 years, while waiting for the patent to be approved is also time consuming. All the products are probably sold out during this period.

2. Three steps for patent mining

Disassembly: Disassemble the research and development results according to the product tree.

Analysis: Analyze the disassembly results and pick out the creative elements.

Combination: Combine the creative elements to form a technology net.
