Dear Mr. Streifer,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located 15 series in the Records of the Patent and Trademark Office (Record Group 241) that are indexes to the Patent Case Files, 1/1/1836 - 12/31/1978 (also in Record Group 241) which may assist in locating the patents you seek. We also located the Index to Administrative Office Records , 1942 - 1945 in the Records of the Office of Scientific Research and Development (Record Group 227) that includes patent information. These indexes have not been digitized. For more information, please contact the National Archives at College Park - Textual Reference (RDT2) at email@example.com.
The patent case files are located at the National Archives at Kansas City (RM-KC).
Next, we located 22 series of the Manhattan Engineering District (MED) in the Records of the Office of the Chief of Engineers (Record Group 77) that may include references to the patents filed. For more information, please contact RDT2.
Plus, we located 6 series of MED in the Records of the Atomic Energy Commission (Record Group 326) that may include records relating to patents. These series have not been digitized. For more information, please contact the National Archives at Atlanta (RE-AT) via email at firstname.lastname@example.org.
Lastly, we located 6 series & 1 file unit in various record groups that pertain to the Manhattan Project. Only the file unit is digitized and available online using the Catalog. For more information about the non-digitized record series, please contact RDT2.
Due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from RDT2, RM-KC & RE-AT. We apologize for this inconvenience and appreciate your understanding and patience.
We hope this is helpful. Best of luck with your research!
