As a follow-up to yesterday's post:
1. I eventually got the acknowledgement of the filing of the POA.
2. The ILPTO sent out the same notice again today, so the problem still isn't fixed.
3. Thank you Israel Patent Office for sending out a notice. At least now we know there's a problem, it's not just me, and since the ILPTO is aware of the problem, it will be fixed at some point. In contrast, the USPTO's electronic systems often go on the fritz, and the USPTO doesn't bother to tell anyone or update its "systems status page" to reflect the outage or problem. Or, if it's a particularly egregious screw-up (like systematically mis-calculating patent term adjustment, or allowing third parties access to files that are not yet meant to be public, both of which happened in the past year), it sends out a notice after the fact saying, "We messed up, we fixed the issue so that it won't recur, but now the onus is on you to make sure that our mistake didn't injure any of your clients."
