how to call EPO(European patent Office) web service to get weekly updates using c#.net

I am developing an application which calls EPO webservice to fetch data and it inserts to the database. Plese can anyone let me know how can i get weekly updates from EPO calling their webservice using c#

Ref wsdl url : http://ops.espacenet.com/开发者_运维技巧OpenPatentServices/end-of-life/webService/getPatentData?wsdl .

Don't bother trying. That service is being discontinued next month (was supposed to have been quite a while ago). Consider using an up-to- date version instead.

We have a brand new, more powerful OPS RESTFUL service http://www.epo.org/searching/free/ops.html

Additionally, on the page I mentioned above, you can find 100 pages full of examples documentation on how to use OPS.

Study the manual and see if it is possible to send set the period for updates. if not then you will have to write a service or a job to fetch the data on a weekly basis.
