Why is there no "execution" rule for patents?
fatdog789: Expense. What if the invention is very expensive to make but the inventor is a high school dropout living above his parent's garage?
This one requirement now completely invalidates his rights to the invention he created; this means less incentive for people to invent. It also applies against companies as well, b/c now they have to invest resources in researching an invention and in developing the production line to crank it out if it works.Timeline. You require them to build the product before it can be patented, which means a massive incentive before they even know if they'll get any protection.REDUNDANT. Patent law already has a "reduction to practice" requirement. This requirement usually requires the inventor to build a working copy (and this is the most common way that the RTP requirement is met) or to provide detailed enough instructions that any person in the same art could build a working copy of the invention.
