Patent 5533051 [0] is a classic. Some quotes:

  A second aspect of the present invention which further enhances
  its ability to achieve high compression percentages, is its
  ability to be applied to data recursively. Specifically, the
  methods of the present invention are able to make multiple
  passes over a file, each time further compressing the
  file. Thus, a series of recursions are repeated until the
  desired compression level is achieved.

  ...

  Thus, one skilled in the art can see that by keeping the
  appropriate counters, the direct bit encode method of the
  present invention is effective for reducing an input string by
  one bit regardless of the bit pattern of the input string.

What would one say about the examiner now?
