In general, the contents of United States patents published before March 1, 1989 are in the public domain.[1]
In specific cases, patent applicants and holders may claim copyright in portions of those documents. In those specific cases, applicants are required to identify the portions that are protected under copyright, and are additionally required to state the following within the body of the application and patent:[2] [3]
The original patent should be checked for the presence of such language before an assumption is made that the contents are in the public domain. (This template can be replaced by {{PD-US-patent-no notice}} in such cases.) Note: This only applies to images published before March 1, 1989. Patents published after that date are most likely copyrighted, unless in the public domain for another reason, such as {{PD-ineligible}}.

Hmotnostní spektrometrie doby letuHmotnostní spektrometrie doby letu (TOFMS) je druh hmotnostní spektrometrie, při kterém se poměr hmotnosti a náboje iontů určuje měřením doby jejich letu. Ionty se urychlují elektrickým polem o známé intenzitě. .. pokračovat ve čtení
