Although it is highly unlikely that Ya'qub (as)'s eyes were fixed from a sweaty shirt that would have had to have been soaked and dripping, it would still be quite an inspiration for the man to imagine such a scenario and work off it.
note. a patent doesn't necessarily prove success, it is just to safe-guard one's research efforts and/or business model from being plagiarized by other businesses.
many patents are left dormant and expire, some people even make patents just to sell in the near future "in case it might work" and someone might want it. A bit like those who buy phone numbers and license plates.
Some production, lab tests and testimony would go a long way.
