03 / Verification

Verification

Find the official registry independently, then compare the names and numbers we publish. Review the original records and reach your own conclusion.

Trust through independent verification

You can independently verify how the activity organizer, the trademark and patent rights holders, and the company are connected. The product's rights holder, who is also its inventor, is the company's sole shareholder. Payments received for future business cooperation and prize payments are handled through accounts in that person's name or the company's business accounts. You can also verify the named account holders and their corresponding connections.
