The official fees incurred for filing, prosecuting, registering and renewing patents, designs and trademarks in Israel are linked to the cost of living index. Twice a year, on 1 January and on 1 June, they are adjusted. It seems that living in Israel is ever more expensive, and each adjustment makes each fee a few Shekels more.
WIPO works differently. From time to time their fees for PCT related services are adjusted, but not necessarily upwards.
As of 1 January 2015 the basic international filing fee for a PCT application will drip from $1471 to $1384. Excess page fees will drop from $17 a page to $16 a page.
If one elects the EPO as the international Search and Examination Office, the search will cost $2366 instead of the current $2545.
Using PCT Easy saves $104 per application, and filing electronically as XML or similar saves $208. It is possible to combine these and file electronically using PCT Easy, saving $312.
