Case Description:

In this case, you will study and investigate copied image from a machine that was under the use of Mr. Charlie. The case belongs to two competitors’ companies; (i) M57.biz and (ii) Project2400 and the communication among their employees.

Both companies are famous for providing innovative and creative ideas to attract companies, inventors, as well as investors. Research and development were the main domain areas for both companies. These companies are always trying to launch new ideas to improve their revenues, and number of customers by generating quality work.

Mr. Charlie was an employee of M57.biz. The company was recently established and is working hard to give strong competition to other companies in the market. The company has a number of employees working under the supervision of the CEO. During the period of November 16, 2009, and December 9, 2009, the company was discussing new research ideas and was planning to publish two research patents. Mainly, Email was the communication channel in order to discuss the formal project ideas and assigned tasks to the team members. In addition, there were some other informal discussion topics that were part of their communication.

On the other side, the company Project2400 was a big competitor of Mr. Charlie’s company. With hard work and dedication, this company also established a reliable name in the market as a research and development industry.

The investigation was initiated after finding out that Mr. Charlie was allegedly involved in selling the ideas to one of the employees belonging to the competitor company. Surely, behind all of these illegal activities, Mr. Charlie’s main concern was to earn unlawful financial benefits (that is still not confirmed). According to the ch

arges applied on Mr. Charlie and during the preliminary investigation conducted internally, the company found him “guilty”. On the other side, Mr. Charlie was continuously denying the charges and recorded the following statements during initial investigations:
