The ePCT system has a very helpful feature which permits you to see a preview of what will eventually be the first page of your published PCT application. This feature was mentioned in an article in the Practical Advice section of a recent issue of the PCT Newsletter. I am delighted to be able to tell you that the article mentions a mistake made by yours truly and the way I fixed the mistake.
The WIPO web site has a searchable index for the Practical Advice column, and through it you can reach individual articles. The individual article mentioned above may be seen here. As I say, in this article you can learn about something I screwed up and the way I was able to fix it, namely a 92bis change.
