Patent Searching

Why search?

Searching can help you see whether there is anything similar in the market place which may affect the likelihood of your invention getting patent protection. A search can avoid wasting time and money by applying for protection for something that has already been invented. It can also be useful to obtain competitive product information and to make sure your product does not infringe someone else’s patent.

  • Search published patents, the internet and trade publications to find out if your invention is new and to check for similar inventions.
  • Check to see if your IP is being infringed
  • Check patent documents for possible solutions to technical and production problems. 
  • Obtain product information on your competitors for research purposes and to establish what is already known.
  • Before beginning to manufacture, check whether you could be hindered by an existing patent.
  • Use a search to find potential licensors and business partners.
  • Check if a similar patent to your invention already exists.
  • See if there are patents available to license in your area of technology.
