i want to do a patentscope search for patents that HAVE ALL 4 of these keyterms: centrifugal force, pendulum, torque, reciprocation.
how do i type it in simple search and advanced search? is it: CENTRIFUGAL FORCE AND PENDULUM AND TORQUE AND RECIPROCATION? this method doesn't seem to work though.
You can type "CENTRIFUGAL FORCE" PENDULUM TORQUE RECIPROCATION in the Simple search "English text" field. It will search applications containing all these keywords either in the title, abstract, description or claims using stemming.
Please note that "centrifugal force" are between quotes to force the two keywords as a single term so that applications containing centrifugal and force apart are not matched.
