Charles, Thanks very much for your input on my problem with a tsNet error that occurred when trying to get patent text information from the USPTO web site. I finally found a way around the issue by using libURLDownloadToFile. That, of course, is a more crude way to get what I want since my ultimate goal is text which I can edit or from which I can extract individual pieces of information like inventor names, patent issue date, etc. Since libURLDownloadToFile creates a file on disk, I then need to open the file and read the data into a a variable, and then delete the file (which is no longer needed) before I can get to my real work. It is extra steps, but at least no tsNet errors like “put URL ____ into tVariableName” suddenly started giving me!
