1.Every entry should be made in ink.

2.Each page should include the appropriate project number or other information identifying the work being performed.

3.Pages should not be removed.

4.Entries should be kept current and in chronological order. Blank pages should not be left.

5.Each page should be signed and dated.

6.Entries should be written on pages of the notebook directly. Do not write in any paper them past them in the notebook.

7.Clippings, photographs, or other external data should be included if possible by pasting them in the notebook and signing, witnessing and dating them.

8.Incorrect entries should be crossed out with a single line rather than erased or obliterated.

9.Pages containing items of possible patent interest should be signed by at least two witnesses who are not co-inventors of the described development and who understand the development. Witnesses should write beside their names ”Witnessed and Understood”。
