The issue of public disclosure of industrial design raises a number of doubts in doctrine and case law. Due to the dynamic development of the industry, there are new possibilities to make the design public and, as a consequence, a new catalog of evidence which the parties refer to this circumstance. A proof of a number of controversies are the printouts of websites submitted as evidence of public access to the design. In this case, the main difficulty is determining the date on which the design illustration of the design was made available. It is worth considering whether Internet evidence can even be considered as evidence of the public disclosure of an industrial design, and if so in what circumstances.
