When I contacted the state department they told me that ideas can not be registered, ideas have to be expressed in something physical, software, etc.
There are some things that can not be registered for example:
“It is not possible to inscribe mere ideas, concepts, proposals or systems that are not incorporated into a means of expression contemplated by the law or incorporated in a way that does not comply with the legislative intent of protecting the creativity of the author. In this sense, it must satisfy a minimum but sufficient level of originality.
Nor is it possible to inscribe those works created to advertise or promote goods or services, those of the officials of the Commonwealth created in the performance of their duties, nor compilations, anthologies or abstracts of fragments of works by other authors.
Finally, it is not possible to inscribe in the Registry any inventions of novel mechanisms or processes of purely utilitarian or functional nature nor the names of products, groups or companies, nor mere titles”
