If today's patent offices existed pre-1450...

Hey. Someone invented a way of securing an opening using these things called Lock and Keys. I'd better patent:

- Securing a dwelling's entrance using a lock and key;

- Securing a dwelling's view-port or window using a lock and key;

- Securing your writing desk using a lock and key;

- ...ad nauseum...
