<div><p style="margin-bottom: 12pt;"><b><span style="font-size: 10pt; color: rgb(31, 73, 125);">U.S. patent laws differ from
European laws in several respects, including a "first to invent"
rather than "first to file" rule. Therefore, in the U.S. you may publish
or put your invention to commercial use for up to one year and still patent it
afterwards. <br></span></b></p></div></div></blockquote></div><br>Yes, you are right. On the other hand, after one year, the divulged invention falls into public domain. And of course you risk to have to challenge any patent that a third party may have filed in the meantime alleging prior invention.<br>
