There are many resources available to help you search for "prior art" documents, to help you assess the novelty of your invention. Be aware that it's sometimes better to file your application without doing a search. Each case should be judged according to its own circumstances and we can advise on this, but for those who do wish to carry out a search the links below should prove useful.
These links are useful for finding out more about the application process in the local jurisdictions, and for searching and for finding details of particular patents of interest.
