I am looking for a way to find the most cited patents in a field as a method of getting to know the basics and state of the art fast while reading the minimum amount of material (even though I suppose it is debatable whether the number of citations corresponds to the quality of the patent).
However, I don't think it would be possible to perform this search with the free tools that I normally use (espacenet, google patents). Is this true or is there a method that I am missing? Is this possible with commercial tools?
