The first step of subject matter based patent analysis for any patent research project is removing irrelevant references which we refer to as “patent filtering”. In this exercise, we have selected a sample from the results displayed by the automated tool after querying it for internet connected vehicles. Our subject matter experts then reviewed those results to filter out irrelevant references. This analysis is used to show the difference between analysis conducted by the subject matter experts Vs the results displayed by the automated tools.
Tool displayed around “184898”hits when searched for internet connected vehicle in Title, Abstract & Claim between 1997 to 2020.
The table shows the comparison of subject matter expert based analysis Vs the results displayed by the automated tools for top 30 assignees (current owner)

• Toyota holding the top position with 2597 references according to automated tool comes down to the second position with 958 references after the same data set is analyzed by M-Son IP's subject matter experts. Hence, we can also see 63% reduction in references when compared to the results displayed by automated tools.
• Samsung holding the second position with 2117 references according to automated tool comes climbs up to the first position with 1191 records as per M-Son IP's analysis. Hence, we can also see there is a 44% reduction in the data set produced by automated tools.
• LG Patents has a 76% reduction and also its rank based on count is dropped from 4th to 9th.
• Huawei slipped down to 27th from 12th with a reduction of 80% after filtering.
The above table shows how unfiltered/raw data produced by automated tools can have a bad impact if a company is making any decisions on the data directly generated from patent databases or other sources without removing the traffic of patents.
