A PI (Private Investigator) conducts an infringement investigation by following these steps:

Identify the Infringement: The first step is to determine what kind of infringement has occurred. This can be copyright, trademark, or patent infringement.

Collect Evidence: The PI will then collect evidence of the infringement. This may include photographs, videos, and documentation of the alleged infringing product or service.

Conduct Interviews: The PI may also conduct interviews with witnesses or people involved in the alleged infringement to gather additional evidence and information.

Analyze Findings: After collecting evidence and conducting interviews, the PI will analyze the findings to determine the scope and extent of the infringement.

Prepare a Report: The PI will prepare a detailed report that summarizes the findings of the investigation. This report will typically include documentation of the alleged infringement, as well as any witness statements or other evidence gathered during the investigation.

Present the Report: The final step is to present the report to the client, who will then decide whether to pursue legal action against the alleged infringer.

It's important to note that conducting an infringement investigation can be a complex and time-consuming process. PIs often work closely with lawyers to ensure that their investigations are conducted in a legally sound manner and that any evidence gathered can be used in court if necessary.
