Lab notebooks


Patents are not necessarily awarded to the first to file, but sometimes awarded to the person who was first to invent. A good laboratory notebook can help protect against claims of prior invention, or to prove prior invention.

Some of the qualities of a good notebook are:

  • Bound and numbered pages
  • Dates when an idea was formed and work begun and completed recorded
  • Initial statements of objectives prior to experiments
  • Full citations of standard protocols
  • Test results attached to notebook, signed and dated across added page and underlying notebook page.
  • Conclusions and evaluation of results
  • Every page signed and dated by inventor and a witness
