Even if your notebook is believed, you have to file in a reasonable
time, or your invention is considered abandoned.  I invented a
step recovery diode circuit, wrote it up in my lab notebook and
filed an invention disclosure.  My company never filed a patent
application and 5 years later another company reinvented it and
patented it.  My prior art not only did not invalidate this patent
(because I never published it) but it didn't even allow us to
practice the invention.  IOW, it was like my invention never existed.
Even the existence of a prototype didn't matter.
