There's a seemingly odd claim in the "Background" section of a granted patent:
In Yuri Gagarin's historic flight into space, he returned in near critical condition after only one hour and forty eight minutes in space. Clearly there was some vital element missing in space that we receive on earth. Yuri had plenty of food, water, and oxygen and since the flight was less than 2 hours he really only needed oxygen. The critical missing element appears to be PEMF—Pulsed Electromagnetic Fields. Since that first flight, pulsed magnetic devices have been used in every space suit and space station. Further studies have been done on earth (zero field studies) with both laboratory animals and human subjects. In a matter of hours without exposure to healthy PEMF's, cell metabolism begins to break down causing bone loss, muscle weakness, depressed metabolism, disorientation and depression.
Because this is a patent that's been granted by the US Patent Office, is it the Patent Office's position that these claims stood up to scrutiny?
