I was advised by an "inventors circle" to protect my idea by copyright rather than obtaining a patent. First question: Is copyright considered a publication in view of the patenting process? Although I am not aware that copyrighted material needs to be published, it is only marked as such when published. Does a data base exist where content of ‘copyright’ can be searched?
Second question: Can copyright exclude others from manufacturing and selling a product when the date of the copyright precedes the date of a patent? Or said differently can copyright void a patent? Can the existence of copyright preclude the issuance of a patent of same nature?
Thirdly: If I ‘protect’ my idea by copyright, would it not exclude everybody including myself to obtain a patent on the subject matter if the above holds true?
Forth: Then there is the field of writing a copyright protects which to my knowledge is essentially written text. I argued that point but the answer was that patents are also written text and cannot cover or claim text as new when it has earlier been copyrighted. This point is a bit confusing, is patent text considered intellectual property in the sense of copyright? Which dominates, patent or copyright?
I very much would appreciate the legality of copyright to protect an invention and exclude others form making and selling a product that is described by copyright where its date precedes a patenting date, allowing the inventor to licence and sell his product covered by copyright.
Thank you for your answers. Rolf Pfeiffer
