When an inventor comes up with an idea, s/he usually searches in Google patent or some other 3rd party patent archive sites with specific keywords related to the invention. Now, those keywords are of course logically accessible to the hosting company (i.e. Google for patents.google.com). If Google wants it can easily look into the keywords and have good insight about what may be the invention is and thus there seems to be a serious confidentiality issue for the inventors.
I wonder if there is any legal agreement with USPTO or any patent authority with the hosting sites so that the searching keywords will be inaccessible to the company or any other confidentiality-preserving action? Or its the unfortunate situation that we all need to deal with.
