# PatentInspector: An Open-Source Tool for Applied Patent Analysis and Information Extraction
## 5 Case Study and Validation
The majority of these inventors are situated in the United States, Japan, the United Kingdom, Ireland, Germany and Israel, as presented in Figure 21. It is important to note that there may be a notable bias in these statistics due to the database of PatentInspector being limited to patents granted by the US patent office, thus skewing the results towards the US. However, the presence of diverse inventors from different countries indicates that HRM is indeed a globally studied field, with multiple individuals interested in patenting their inventions. Figure 14: Granted patents per year for G06Q10/06. Figure 13: Applications per year for G06Q10/06. Figure 16: Granted patents per office for G06Q10/06. Figure 17: PCT granted patents for G06Q10/06. Figure 15: Granted patents per type for G06Q10/06. Figure 19: Citations made per year for G06Q10/06. Figure 20: Citations received per year for G06Q10/06. The G06Q10/06 class is predominantly populated by Cooperation/Organization entities, making up 99.4% of the total. Among them, the leading assignees, presented in Table 9, tend to hold at least 124 patents each in the G06Q10/06 category. In total, the top 10 assignees collectively possess 3363 patents, accounting for approximately 25% of all patents within the G06Q10/06 category[PERSON] The locations of the assignees, shown in Figure 22, closely mirror those of the inventors, but with a greater concentration in the prominent tech hubs across the United States, which is once again a result of USPTO being the only source of data. Among them, several reputable companies and organizations are visible, which employ a large pool of personnel and manage projects and resources on a complex scale, as well as companies that are involved in the Software and Informatics sectors such as IBM (USA), Microsoft (USA), Oracle (USA) and Accenture (IRL). \begin{table}
\begin{tabular}{c c} \hline \hline
**Inventor** & **Invention Count** \\ \hline [PERSON], II & 52 \\ [PERSON] & 46 \\ [PERSON] & 46 \\ [PERSON] & 38 \\ [PERSON] & 33 \\ [PERSON] & 31 \\ [PERSON] & 29 \\ [PERSON] & 27 \\ [PERSON] & 27 \\ [PERSON] & 27 \\ \hline \hline \end{tabular}

(JP) & 182 \\ THE BOEING COMPANY (US) & 160 \\ Damian Wasserbauer General Electric Company (US) & 156 \\ Hewlett-Packard Development Company, L.P.

Table 9: Most prominent assignees for G06Q10/06. PatenInspector was also employed to perform the LDA method for topic modeling, deleting the 20 most frequently appearing words in the document, using the default parameter of 10 topics. The execution of LDA yielded a coherence score of 0.523, meaning that the resulting topics were well-rounded and broad [25]. Subsequently, PatentInspector categorized these topics according to their patent share and the CAGR of their patent share during the period between 30 March 2015 and 28 March 2020, which covered 5 years before the last grant date to the last grant date itself, using the default settings of PatentInspector. Of course, the user has the capability of modifying any of these parameters according to his/her preference. It should be noted that this is an indicative, demonstrative execution of LDA, for the purposes of the case study, and not necessarily the optimal model. However, based on the outputs of the tool, we can provide some interpretations for the HRM field.
