ADVICE FOR INVENTORS
A Patent Search is always advisable before embarking on a costly journey towards successful exploitation of an Idea or Invention, but a Patent Search should only be carried out after at least a Conceptual description of the Idea or Invention has been filed at the UK Intellectual Property Office (IPO).
This will provide you with initial protection of your intellectual property (i.e. your Idea or Invention) whilst you, or we, investigate matters further.
Unfortunately, it is better to find a great deal of published information by searching on the basis of broad search terms, than by defining your Idea or Invention in the search string in order to narrow down what comes back after the search. A search based on broad search terms which do not define your Idea or Invention means that you will have to sort through the great many published patents that come back, but you will be protecting your intellectual property.
A recommended alternative is to submit Claims to the IPO along with your patent specification, since this will provide a better search result because the Claims are what you are claiming to be your actual Invention, and they will be dealt with under the conditions of security operating at the Intellectual Property Office, which you will not get by doing a search via the Internet, where anyone with an appropriate presence on Search Engines will be able to see the words in your keyword search as part of the analytics, e.g. Google Analytics, which they will have have access to.
Take care not to define your Idea or Invention in the Title because that could be seen in a Patents Journal even though you may not wish to have the application published. It can always be changed under the advice of a Patent Examiner, so, initially, keep it broad.
