OK, so I am installing, one month from now, a publicly viewable structure. My question is, if I file a PPA first before it is publicly viewed, will that alone, null and void any later patent, because it was viewed by others within my provisional year, and not covered from the World with a black lead curtain. If one files a provisional patent, are they under liability to conceal it from public eyes, and if I am going to show it publicly, would I be better off just filing the patent myself within the next two weeks? If something which is new and novel will be seen by thousands a month from now, what is the best mode fo obtaining the intellectual property necessary to still have it 20 years from now? Any help would be great. Thank You Very Much!
