Record Keeping for Inventions


by Becky Mahurin

In the United States, unlike much of the rest of the world, patents are allowed on the basis of first to invent, not first to file. Therefore, accurate and detailed record-keeping is essential to establishing the date the invention is conceived and reduced to practice. The following principles are important elements of good record-keeping:

  • Make timely entries in a bound notebook with consecutively numbered pages.
  • Record laboratory data, drawings, and complete description of problem, solution, and design.
  • Always use ink. Never erase. Draw lines through mistakes and unused space then initial and date.
  • Include both successful and unsuccessful experiments.
  • Make regular entries, explain any lapses in experimentation due to vacation, equipment availability, etc.
  • Sign and date all entries.
  • Have each entry or each block of entries signed and dated by a witness who understands the experiment, but who is not a coinventor.P
  • Permanently attach to your notebook any additional documentation such as graphs, pictures, etc. Again, sign and date each piece.
  • An invention disclosure filed with the technology transfer office is used by university inventors as additional evidence of invention.

Many of the above practices are those you already use routinely in your laboratory notebook. These practices are essential in the patenting process and may determine the validity of a patent when more than one patent is filed on the same or related discoveries.

If you have questions, call me at 994-7868. Next month I'll discuss important elements of nondisclosure or secrecy agreements in the patent process.
