MWO-related patents
The two documents most readers want are US1962565A and US2351055A. The first is the concentric split-ring apparatus. The second is the later tube design. The French filing FR732276A is present as metadata in the archive, with official scan retrieval still pending.
If the search intent is practical construction, start with the dimensions guide and then test a single-ring assumption in the calculator.

How to read the patent record
Patents can prove that a claimed apparatus, title, filing date, inventor name, and set of technical claims existed. They cannot by themselves prove clinical effectiveness. This is especially important for Lakhovsky because the best-known device patents are electrical documents, while the medical claims come from publications, press accounts, and later retellings.
Known caveats
- Some non-U.S. patents are represented only by Google Patents metadata pages in the local archive.
- One unrelated U.S. patent was captured during research and explicitly marked out of scope in the source log.
- Patent-family relationships should be rechecked against INPI or Espacenet once anti-bot blocks can be handled manually.
