I have been using the PatentScope web service to get information for various international application numbers for several months. However, as of Wednesday (June 28), the service is not consistently working. On some computers, the request will always fail, while on others it will work some times, but not others.
If it's helpful, I'm using C# with the wsdl definition provided, specifically the method getIASR(String iaNumber), and am getting the following exception:
System.Net.WebException: The request failed with an empty response.
