(Update: it took more than six months from when we reported the bug, but USPTO did finally fix it. See blog article.)
When you are e-filing a new utility patent application in EFS-Web, one of the ways to make the priority claim is by means of a web-based Application Data Sheet. There’s a place in EFS-Web where you can say that you are adding a priority claim, and it gives you a drop-down menu of patent offices where your priority application might have been filed.
USPTO has had users alpha-testing and beta-testing its new system called Patentcenter, which will eventually replace EFS-Web. Patentcenter has a similar web-based ADS function that allows you to make a priority claim when you are filing a new patent application. When you use this function, eventually you reach this drop-down menu of patent offices where your priority application might have been filed. Can you guess which well-known foreign patent office is missing from this drop-down list in Patentcenter? Continue reading “Can’t claim priority in Patentcenter?”
