Readers will recall (perhaps from my blog post of July 15) that the search fee for ISA/EP will increase (for US filers) on September 1, 2017. This offers an opportunity to save a little money.If your client is planning to file a PCT application in the next week or two, and is planning to pick ISA/EP, consider filing it on August 31 rather than September 1. This will save $107 in search fees.
