Hello Mr. Streifer,
To answer your questions:
1. Where can I find a complete list of 45,000+ vested patents, listed by patent number or inventor?
While we do not have a complete listing of the vested patents, the records are available to view in Record Group 131 Office of Alien Property. We do not know how many of the vested patents we have.
Patent case files can be found in multiple series (see below). The records would include those patents for which claims were filed after vesting. If some were vested but no claim was filed, then we would not have that claim.
- RG 131 Entry P 67 Patent Claims Case Files, 1942 – 1963 ("A" Patent Claim Case Files) (NAID 7489302)
- RG 131 P 127 Vested Property Case Files, 1946- ca. 1966 (NAID 12006510)
- RG 131 P 33 Vesting Order Case Files, 1942-1966 (NAID 7329938)
The latter two series include patent files but are not limited to the vesting of patents. For each above series there are several indexes which may contain information about the underlying case that researchers can consult. Information about the indexes can be found in the above series’ Catalog descriptions (under the field “Finding Aid Type”).
A summary description of property vested from select case files found within RG 131 P 33 Vesting Order Case Files, 1942-1966 (NAID 7329938) can be found here: http://www.archives.gov/iwg/declassified-records/rg-131-alien-property/case-files.html
You may also be interested in the following series:
- RG 131 A1 1036 Correspondence and Other Records Relating to Patents and the Office of Alien Property Custodian, 1942 – 1951.
2. Where can I find a list of those 300-odd patent classes?
A list of patent classes can be found here: CLASSES WITHIN THE U.S. CLASSIFICATION SYSTEM
You may also want to look in the Administrative and Operations records of the U.S. Patent and Trademark Office (RG 241 - please see below).
3. Which four patent classes weren't vested, and why?
A good place to look for the answer this question would be in the annual reports of the Office of Alien Property, found here:
You may also want to contact the records officer of the U.S. Patent and Trademark Office (scroll to bottom of page):
4. Could those four classes have been related to the atomic bomb, such as fission, uranium, etc.?
Again, a good place to look would be in the annual reports of the Office of Alien Property:
