# PatentInspector: An Open-Source Tool for Applied Patent Analysis and Information Extraction
## 5 Case Study and Validation  
To effectively showcase its functionalities and usefulness, in this section, PatentInspector is employed to perform a PA focused on the CPC group \"G06Q10/06\". This group spans a wide array of domains, including resource management, workflow optimization and human and project management, as well as enterprise planning and modeling. To validate the findings, a comparison of the results is made with a replication of this case study using the Lens software [102], which is hailed as an established source both for patent data retrieval and for PA insights [113; 114; 115; 116]. The results indicate that the descriptive insights and citation analysis extracted by PatentInspector largely correspond with the results from Lens, indicating that the constructed tool produces valid PA outputs. However, it should be taken into account that all comparisons were made with patents from the USPTO and not from the global patent landscape. The detailed description and comparison of the tool with Lens [102] can be found in the Supplementary Materials, along with three additional case studies conducted to further validate PatentInspector. Our analysis, consisting of 13,424 patents retrieved from the filtering system using the \"CPC = G06Q10/06\" filter using exact matching, commences with a descriptive analysis, provided by the Descriptive Analysis Tab, starting with statistical measures, followed by an exploration of the variables over time, an investigation of entity-specific data and a subsequent topic analysis from the Topic Analysis Tab, concluding with a citation analysis from the Network Analysis Tab. In Table 7, we present basic statistical measures. In this context, it is important to highlight that the distributions of applications and grants tend to fall around 2021-2023 due to the absence of data from PatentInspector. As previously detailed in Section 4.1, PatentInspector exclusively handles granted patents. It is noteworthy that the statistical table indicates an average pre-grant duration of 3.91 years. Figure 12: The user interface of the Patents Tab of PatentInspector. \begin{table}
\begin{tabular}{c c c c c c} \hline \hline
**Variable** & **Avg** & **Med** & **Std** & **Min** & **Max** \\ \hline Claims count & 20.05 & 19 & 14.22 & 1 & 539 \\ Figures count & 16.1 & 10 & 29.01 & 0 & 2045 \\ Sheets count & 14.25 & 9 & 29.61 & 0 & 2037 \\ Years to get granted & 3.91 & 3.48 & 2.19 & 0.23 & 19.23 \\ Title word count without processing & 8.93 & 8 & 4.40 & 1 & 52 \\ Title word count with processing & 6.65 & 6 & 2.9 & 1 & 32 \\ Abstract word count without processing & 116.58 & 119 & 39.33 & 8 & 344 \\ Abstract word count with processing & 70.29 & 71 & 23.96 & 0 & 222 \\ CPC groups count & 7.30 & 5 & 13.95 & 1 & 205 \\ IPC Subgroups count & 3.37 & 2 & 4.97 & 1 & 104 \\ Assignee count & 1.01 & 1 & 0.14 & 1 & 6 \\ Inventor count & 3.17 & 3 & 2.33 & 1 & 63 \\ Incoming citation count & 25.24 & 6 & 66.42 & 1 & 2091 \\ Outgoing citation count & 26.09 & 9 & 69.3 & 1 & 2328 \\ \hline \hline \end{tabular}

Table 7: Statistical measures for G06Q10/06. Consequently, it is reasonable to infer that patents submitted within the last three years are likely not included in the PatentInspector database. Additionally, USPTO is the only patent office that granted patents for G06Q10/06 solely because PatentInspector contains only patents from USPTO currently. Upon an examination of the charts (Figures 13-20), it becomes evident that the domains associated with HRM present an upwards trajectory as the patent grants and applications are consistently on the rise. Regarding PCT status, while it presents an upwards trend based on Figure 17, 12,517 patents (93.2%) have not applied for PCT, while only 907 (6.8%) of the total patents have been granted PCT status. The most prolific inventors (Table 8) typically possess a minimum of 27 patents each within the domain of human and resource management.
