Loyal readers will recall that recently I did a large number of test welds to measure welding currents generated by my new inexpensive stick welder (blog article). I had been using my smart phone to log real-time current measurements via Bluetooth from a clamp-on DC ammeter (blog article). Part way through the large number of test welds, I was astonished to see that my smart phone had powered itself down. I tapped the power button and coaxed the phone back to life and completed my current logging activities, and eventually figured out why the phone had so mysteriously and abruptly powered itself off. A tiny bit of hot steel from one of my test welds had flown several feet and had landed on the glass screen of the phone, and had melted a small crater in the glass. You can see the crater, which is less than one-fourth of a millimeter in diameter, in the photomicrograph above.

Yes there are at least five DAS Depositing Offices that charge a fee to obtain a DAS access code! And there are at least six DAS Depositing Offices for which it is known that they do not charge a fee.
As of March 19, 2023, there are 36 DAS Depositing Offices. They are listed in the table on this page. The rightmost column lists information, if any, that is known about whether or not a particular Depositing Office charges a fee for a DAS access code.
As you can see, there are twenty-five DAS Depositing Offices for which it is not known whether or not a fee is charged for a DAS Access Code. I invite practitioners who practice in the Offices listed below to let me know if they are aware of their Depositing Office charging a fee for a DAS access code, and, if so, the amount of the fee.
Kindly detail the fee charged for the particular application types in your Office:
National industrial design applications
National patent applications
National trademark applications
National utility model applications, and
PCT international applications.
It would be particularly helpful if you can provide a URL to a place on the web site of the Office detailing the fee.
As we know, the “springing forward” of clocks for Daylight Saving Time happens at about 2AM. This “radio controlled” wristwatch does the DST adjustments automatically. I happened to be awake when it happened just now, and you can see a video recording of the automatic adjustment carried out by this wristwatch.
