US patent act requirements are all relatively straightforward. An invention needs to be new, inventive and serve an actual purpose that can be put to good use in order to qualify as a patentable invention. However, there are many terms and conditions which relate to the requirements which might disqualify an invention from being considered patentable according to the US patent act such as:
If an invention is public knowledge, been used commercially before or there is another invention on the market already which is similar the invention, as the invention will then not be regarded as novel as explained on https://inspirationfeed.com/inventhelp/.
If a skilled person in the same field of trade considers the invention to be obvious, as the invention will not be regarded as inventive.
If public disclosure of the invention occurred before applying to file the patent – searches should be conducted through patent databases as well as literature databases to confirm that an invention is novel.
If the exact or similar invention exists in another country then the invention will no longer be seen as novel and the invention will be denied a patent application.
However, if someone would like to copy an invention or manufacture something similar, of another inventor in another country, even though he or she will be prohibited to apply for a patent due to the fact that he/she is not the inventor themselves, the person can perform an infringement search through the US Patent Office. And, if no American patent exists for that invention, that person may manufacture and trade with that invention as written in https://southfloridareporter.com/how-inventhelp-can-assist-with-new-invention-ideas/ article.
