FAQ

Can I visit without a reservation?

Do not assume walk-in access. Confirm the date, group size and purpose directly with the operator.

Can visitors see patented technology?

Not necessarily. A visible process is not proof of a patent; specific rights require a separate public-record check.

Is English-language support available?

Permanent English support could not be confirmed. Contact the venue early and arrange interpretation if needed.
