Would publishing an idea to an invention (on the internet) act as a prior art with a priority date in a later fild patent application? For how long such protection lasts?
For example, if someone has an idea to an invention such as a software application but still need time and money to acually reduce it to practice, so he cant yet file a full patent application. A US provisional patent application is a possible solution but also involve fees and allows only one year to file actual application which inventor thinks not sufficient. would publishing the idea behind such invention act as a first defense allowing more time for inventor at a lower cost than provisional application of patent? What disclosure options count? Recognized Websites?
Help much appreciated
