Patent Search




Let’s talk about where to start!

When searching for patents during a patent application or patent infringement defence, researchers have many tools available. Several free patent search tools provide access to a single country’s patents, such as the USPTO and Canada’s CIPO. Others offer an international patent search, like Espacenet and Google.

Free is not necessarily cheap

With so many free patent research options available, why use a commercial product like LexisNexis TotalPatent One? The short answer is: to ensure optimal results and to guarantee your job. If you need more convincing, read on:

  • Free tools do not usually offer translations. Unless you are a linguist, that makes international patent search very difficult.
  • Free tools do not always offer the best user experience or search options. If a patent researcher spends two hours on a search that could have taken fifteen minutes using a paid tool, you may end up paying too much.
  • Free tools do not always date back very far, which may mean missing existing patents. It’s surprising how often different generations try to find solutions for the same problems.
  • Free tools are not always complete or have the best indexing. If relevant documents are subsequently missed, the entire patent application may be invalid.

The solution is to use the best of both worlds: free and commercial. That is where TotalPatent One comes in.
