As I reported on May 5, 2017, the Israel Patent Office made plans to increase the search fee for US filers from $911 to $963. The fee change takes effect today.
At the present time, very few US PCT filers pick ISA/IL. So this fee increase will not affect very many US PCT filers.
Most US filers file their PCT applications in EFS-Web because most US filers use RO/US for their PCT filings. EFS-Web was updated today to reflect this new fee amount. So there is not much risk of a US filer accidentally paying the old (smaller) fee.
