Why Can Patents Be Granted for Multiple Similar Inventions?

When a client reviews prior art, documents such as patents, patent applications, journal articles, goods and other documents that disclose an invention, she is typically struck by how numerous of the patents are for particularly similar inventions. How can each of these patents have been granted when they share so lots of common elements? There appears to be so a lot overlap.

Overlap is in reality an vital part of the patent program. To know how the overlap operates in practice, 1 ought to comprehend the most standard principle of patent law - a patent provides the holder the appropriate to cease others from practicing her invention, but it does not give the holder the proper to practice her own invention.

For example, suppose you invented a unicycle with the longitudinal stabilizer. The stabilizer created it considerably simpler to ride a unicycle, and you successfully patented invention. I get 1 of your unicycles, and mainly because I'm less coordinated than you, come across that I also need a latitudinal stabilizer. With both the longitudinal and latitudinal stabilizers, even I can ride a unicycle, and I patent that invention.

Even even though I hold a patent on a unicycle with the longitudinal and latitudinal stabilizer, I can not build my invention with out infringing your patent for the reason that my invention contains a unicycle with a longitudinal stabilizer. Even so, I could prevent you from constructing a unicycle with each longitudinal and latitudinal stabilizers. If the industry of klutzes who want to ride a unicycle is large adequate, you could get a license from me, or I could get a license from you, or we could cross license, so that unicycles with each stabilizers could be built.

This feature of patent law allows inventors to defend incremental improvements to existing items. It advantages society by encouraging innovation even when the innovator may well be precluded from practicing his innovation with no a license from the patent holder of the core invention.

It also means that countless patents are granted for inventions that are fairly similar. Each and every of those comparable patents are incremental improvements to or variations of the core invention. The inventors of the improvements and variations that are adopted should be and are rewarded for their creativity. If one does not want to pay them, he is no cost to produce a product without having their innovations.

By allowing applications for comparable inventions to be granted, innovation is encouraged, but at the cost of extra intellectual property to give some thought to and assessment when making a item. The plethora of similar patents in the United States is top viewed as powerful evidence that innovation is alive and nicely.
